Cave inside.

    When Chen Yun took a deep breath, a strong suction force came from his nostrils.

    The spiritual essence of the White Slaver from his palm was immediately drawn into it.

    Chen Yun immediately activated the secret method, sending the essence of the spiritual essence of this original force along his nasal cavity into the Mudan Palace.

    He was not the first time to refine the essence of the spiritual source, he had done it once before, so this time it was incredibly skillful and natural.

    Refining the essence of the spiritual source, certainly cannot use the fourth turn of "Mr. Chen's Inner Dan Zen" practice method.

    Chen Yun was using the "Yin Spirit Method," which is what he did last time.

    Of course, it is not necessary to use the fourth turn of "Mr. Chen's Inner Dan Zen" practice method.

    It is to first refine it once, and then use one's own inner dan art to refine.

    Generally speaking, it takes ten months of cultivation to perfect the spiritual essence.

    The scripture records: After ten months of cultivation at the Central Pass, it becomes perfect and can be transformed into a god.

    That is to say, when all the preliminary conditions for your spirit essence to leave the body are met, it will take another ten months of time to refine completely.

    With the power of the spiritual source from White Slaver's essence helping him, Chen Yun naturally doesn't need to go through all that trouble.

    He continues to refine this essence of the spiritual source.

    Perhaps it was because his own strength had greatly increased, this time the refining speed was incredibly fast.

    In just a short while, he was able to "detach" a small group from the essence of the spiritual source of White Slaver.

    Chen Yun controlled his own spiritual essence, absorbing and refining the ancestral qi that had been produced, making his spiritual essence much stronger.

    This ethereal sensation is something that ordinary people cannot sense.

    He is different, his cultivation has already reached the brink of the Earthly Realm, naturally he can easily feel the strength of the spiritual essence.

    The third group.

    The eighth group.

    After one day, Chen Yun had refined twelve groups of the essence of the spiritual source.

    So far, the essence of the spiritual source from White Slaver is not as unnoticeable as the last time, but it is already evident that a small piece is missing.

    "It seems I am indeed much stronger than before, and the speed at which I refine the essence of the spiritual source is several to hundreds of times faster than it was before."

    Chen Yun secretly pondered, "Not in a hurry, let's first use the fourth turn of 'Mr. Chen's Inner Dan Zen' practice method to refine these newly refined ancestral qi, and see how much it has actually strengthened."

    Just absorbing and refining the ancestral qi produced is not enough to directly make the spiritual essence leave the body, it also needs further "refinement".

    This further "refinement" is actually about purifying the essence of the spiritual essence.

    When the "quality" of the spiritual essence reaches a certain level, it will naturally be able to leave the body.

    After an hour.

    Chen Yun ceased his cultivation.

    He sensed the condition of his spiritual essence.

    Unfortunately, his spiritual essence has not become strong enough to leave the body.

    "As I guessed, since only a small part of White Slaver's spiritual source essence has been refined now, it's indeed impossible to reach the level of spiritual essence leaving the body."

    After "purifying" his spiritual essence, Chen Yun again began refining it.

    A new round of refining began.

    Three groups of the essence of the spiritual source were refined.

    Five groups of the essence of the spiritual source were refined.

    Time passed second by second.

    In a flash, another two days had passed.

    Perhaps it is because the spiritual essence has been upgraded once.

    This time the speed of refining the essence of the spiritual source was clearly faster than before.

    In theory, with the previous speed, two days could only refine a maximum of twenty-four groups of the essence of the spiritual source.

    In fact, Chen Yun has refined thirty groups of the essence of the spiritual source during these two days.

    Now, the essence of the spiritual source from White Slaver is left with only half of its original appearance.

    "Phew, absorbing so much essence of the spiritual source without refining makes my spiritual essence feel like it's 'full,' it's time to refine it now."

    Chen Yun once again runs the fourth turn of "Mr. Chen's Inner Dan Zen" practice method.

    He clenches his teeth thirty-six times, calms his mind, closes his breath, and makes sure there is no inhalation or exhalation in the nasal cavity. He waits until the qi in his body is full and runs through his tongue, and then swallows slowly while focusing on the return to the heart.

    The fluid returning to the heart stirs the fire of the heart and spirit.

    Chen Yun feels the warmth spreading throughout his body, the five organs are hot, the body is slightly sweaty, and the limbs are comfortable.

    After practicing for a moment, Chen Yun felt a sound like thunder in his right rib, and a stream of hot air flowed in from his left rib.

    Suddenly, a stream of flame burst out of his nose.

    The spiritual essence seems to have been greatly nourished, and his facial features have become a bit more "alive" compared to before.

    Unfortunately, this situation did not last long. Chen Yun felt a wave of exhaustion, and then the thunderous sound and the firelight from his nose disappeared.

    "Hmm?" Chen Yun was somewhat pleased, "I can actually produce thunderous sounds within my body and firelight from my nose? It seems I am not far from mastering the fourth turn."

    Once one can master the fourth turn, they will definitely enter the realm of Earthly Immortals.

    Chen Yun was not in a hurry.

    After the cultivation practice was over, the spiritual essence returned to the Mudan Palace.

    He began the third round of refining the essence of the spiritual source.

    ……

    In the practice of cultivation, time flies by.

    It seems like just a blink, but in reality, several days have passed.

    On this day, Chen Yun had just refined thirty-six groups of the essence of the spiritual source.

    He was preparing to enter the state of practicing the fourth turn of "Mr. Chen's Inner Dan Zen" practice method.

    At this moment, he sensed that his spiritual essence had become tens of times stronger than before, and he was not sure if it could leave the body.

    Chen Yun has not practiced the spiritual essence leaving the body before, so he doesn't know yet if his "strength" is enough.

    However, even at this point, he still doesn't have any excitement or joy.

    As if everything is a natural development, and what is meant to happen will happen.

    This is a sharp contrast to his previous state when he was influenced by the heart demon.

    A true cultivator who doesn't have external influences would not get excited or thrilled about whether they break through their level or not.

    At most, they would feel slightly happy.

    Previously, the reason why he got so excited over small breakthroughs was entirely because of the influence of the heart demon.

    In normal circumstances, it wouldn't be like this.

    "Okay, let's try to see if we can make the spiritual essence leave the body. If it doesn't work, absorb the remaining small group of the essence of the spiritual source."

    Chen Yun suppressed all the thoughts in his heart and entered a state of "voidness."

    When he felt a sense of emptiness, his body automatically ran the fourth turn of "Mr. Chen's Inner Dan Zen" practice method.

    The next moment, the qi was filled throughout his body, and his body was warm and comfortable.

    Unconsciously, Chen Yun adjusted the heat to the optimal state.

    At this moment, the spiritual essence, just like before, sank into the golden Dan and formed a "Dan with Holy Fetus."

    The power of the golden Dan continuously refines the spiritual essence, removing impurities within it, making it more "pure."

    Gradually, the spiritual essence seems to have been endowed with a "soul," and its face becomes very lively, as if it is a living person.

    At this point, Chen Yun feels that his spiritual essence does not have enough power to leave the body yet.

    "It seems like it's just a little bit short, I'll refine the spiritual essence for a while and then see."

    Chen Yun practices his own cultivation method and continues to "refine" the spiritual essence.

    The pure and masculine power of the golden Dan is becoming more powerful.

    With the intense refining of the golden Dan, the spiritual essence, which had been closed-eyed, slowly opened its eyes.

    At this moment, Chen Yun feels that a stream of lightning flashes through his body, illuminating his form.

    Not enough!

    Continue refining!

    One hour!

    Three hours!

    Five hours!

    It's been several days in a flash.

    Finally, Chen Yun felt that his spiritual essence was very close to leaving the body.

    As expected, the spiritual essence, having accumulated enough power, began to rise continuously, as if it wanted to break through the heavens and roam the world.

    One inch!

    Five inches!

    Ten inches!

    Finally, the spiritual essence has arrived at the top of the door, ready to break out!

    Suddenly, "bang" one sound, the explosion bursts out in Chen Yun's soul.

    He felt as if his head had collided with an iron plate, and the whole body felt a surge of stars in his eyes.

    At the same time, the spiritual essence fell back into the Mudan Palace in an instant.

    Chen Yun suddenly opened his eyes, puzzled and murmuring to himself: "What happened just now? I clearly felt that the spiritual essence has reached the level of leaving the body. Why can't I leave the body? It's as if I hit something just now. This thing is blocking my spiritual essence from leaving the body."

    He was truly puzzled to the extreme, not understanding what the situation was.

    While he was puzzled, there was a slightly confused voice from beside him, "Master Chen, are you cultivating to the level of Earthly Immortals? Just now, I felt a boundless and limitless power emerging from your body, but it disappeared quickly. Is it like after the spiritual essence leaves the body, there is no longer such power?"

    Chen Yun frowned and looked ahead, seeing Niudali sitting at the door of the cave, "I have not cultivated to the level of Earthly Immortals."

    Niudali was taken aback, "Then what about that power just now..."

    Chen Yun truthfully said: "It should be the power of my spiritual essence about to leave the body and dissipate. However, I encountered some difficulties, and my spiritual essence was unable to leave the body."

    Niudali asked, "What kind of difficulties? Although Niudali is not a member of the True Dao School, since his ancestors were the steed of the Old Ancestor, he has had the chance to see many Daoist techniques. Perhaps I can offer you some help."

    Chen Yun did not ignore this statement because his cultivation was higher than that of the other person.

    Chen Yun truthfully said: "I feel that the spiritual essence in my body has grown to the point where it can leave the body, but during the ascent, it seems to have touched something like a barrier, this barrier prevents my spiritual essence from leaving the body, Brother Niu, do you know what kind of situation this is?"

    Niudali did not directly answer but asked instead: "Where were you about to leave the body from?"

    Chen Yun replied casually, "The spiritual essence naturally rises to the top of the head, so naturally, it's from the top of the head..."

    As he said this, he suddenly realized, "Oh, I understand what's going on."

    Niudali burst into laughter and slapped his hands, saying, "I also know why you were not able to leave your spiritual essence just now."

    Chen Yun laughed and sighed, "After all these years of cultivation, I've made such a low-level mistake. The spiritual essence is not the yang spirit; how can it leave the body through the top of the head?"

    Niudali couldn't help but laugh and clap, saying, "According to 'Qinghua Secret Texts', if there are still impurities in the spiritual essence, it can leave the body through the eyes, ears, nose, or mouth. When it's about to leave, if it leaves from the eyes, the eyes will shine brightly; if it leaves from the nose, the breath will be noisy; if it leaves from the ears, clear sounds can be heard; but if it leaves from the mouth, it is harmful and only beneficial when the spiritual essence is pure and its yin is exhausted. Therefore, it can break through the heavens. Your spiritual essence has not yet exhausted its yin and becomes pure yang. Therefore, you cannot leave your body through the top of your head. Instead of that, try leaving through your eyes or ears. Perhaps you can succeed at once."

    Chen Yun nodded, "I also thought so."

    Niudali offered advice, "Master Chen, I assume it's your first time leaving the body. There are actually many methods to leave the body, but they all lead to the same destination. You can imagine there's a fairyland above with immortals, cranes, fire dragons, and pavilions. Imagine them clearly and then concentrate your mind upwards. In this way, you can successfully leave the body."

    Chen Yun said: "My teacher and Brother Lv, both of them, left the body through thinking of three layers of red buildings on the top of their heads. They thought of going up one layer after another, then jumped down and left the body suddenly. At first, the spiritual essence was like a baby, weak and delicate, unable to move. It's like learning to walk - step by step, training until it can move freely. Then it can start to transform into a cloud of blessings and become powerful and limitless."

    Okay, although this is his first time to leave his spiritual essence, he actually has experience with leaving the yin spirit. He is clear in his mind about how to make the spiritual essence leave the body.

    Niudali said, "Since Master Chen knows how to leave the body, old Niudali won't disturb you anymore. Continue trying."

    Chen Yun said, "Just wait for a moment. The time when my spiritual essence left the body just now consumed a lot of my energy. I need to rest for a moment and replenish it before I can try again."

    Niudali said, "Good."

    Chen Yun felt secretly relieved.

    Thank goodness I left a small group of the essence of my spiritual source earlier.

    Otherwise, if I had consumed all of it, I would not know how long it would take to make up for the failure just now.

    He rested quietly for a while until his spiritual essence became "stable," and then he began to refine the remaining small group of the essence of his spiritual source.

    ...

    It took another whole day.

    Chen Yun finally refined all the remaining small group of the essence of his spiritual source.

    At this moment, he feels that his spiritual essence is incredibly powerful, as if he can go anywhere without a problem.

    "It should be possible to leave the body now."

    Chen Yun sat cross-legged and banished all thoughts from his mind, putting himself in a state of "vacuity."

    This step was as simple as could be for him, and he managed to achieve "vacuity" in an instant.

    To ensure success.

    Instantly, Chen Yun began to try using the experience he had gained from leaving his yin spirit.

    He guides this light with his mind, illuminating the Nidan Palace.

    Chen Yun's current cultivation level made it so that he succeeded immediately.

    He felt a sense of fullness in his brain as soon as he imagined it, and his head seemed like crystal.

    After completing the first step, Chen Yun began the second step of the washing heart method.

    Chen Yun let the "moonlight" shine on the Nidan Palace for a long time, then guided the light down to Chong Lou, all the way to Xian Gong.

    He kept the light in Xian Gong for half an hour, and felt that the palace was pure white and shining brightly.

    At this moment, it seems that the mind has been cleansed.

    "The second step is also completed."

    Chen Yun continued with the third step, the Pure Land method.

    He guides the white light to the center, and stores it there for a long time. In the end, he feels that the center is pure white.

    The third step is successful!

    Chen Yun nurtures his spiritual essence with all his heart and soul.

    Hmm, actually, nurturing the spiritual essence is not very useful. After all, this is a method for leaving the yin spirit, and what it nurtures is also the yin spirit.

    Chen Yun is following this method step by step, so he can find the feeling of having a god.

    The fourth step, the Sealing Sea Method.

    He feels that the light follows the qi down to the lower dantian.

    Instantly, Chen Yun feels that the dantian gradually widens, deep and vast like the sea.

    The fourth step is also successful.

    He starts the fifth step, "Dragon appears from the bottom of the sea."

    Because he has been focusing on the dantian for a long time, the more he focuses, the brighter it becomes, and the wider and broader it expands.

    After a long time, Chen Yun notices the movement of air within the dantian.

    He knows that it's time for the sixth step, "Tiger appears from the bottom of the sea."

    He mentally recites "pure emptiness" and slightly guides his gaze from the bottom of the sea to follow it, feeling that this light has already passed the tail bone.

    At this point, they have reached the seventh step, "The Yellow River flows upstream."

    Chen Yun guides the light from Huayin to the tail bone, from the tail bone upward, following the dorsal meridian.

    The seventh step is complete. Now it's time for the eighth step, 'refining essence to nourish the brain.'

    Chen Yun feels the qi in his body moves with the light, sinking from the dantian to the huayin, passing through the tail bone and following the meridian to reach the head's Nidan Palace.

    The eighth step is completed easily again.

    He continues the ninth step, "The Holy Sun and Moon Shine on Golden Lotus."

    Chen Yun uses the fore-and-aft observation method, imagining that his eyes shine like the sun and moon in the sky. They illuminate the top of his head, penetrate the three gates, and shine deep into the sea bottom, which is Huayin.

    After completing the ninth step, Chen Yun reached the last step before leaving his spiritual essence, which is "Water in the Yangtze River and the Moon in the Sky."

    Chen Yun has all sounds silent, and only uses one will to push upwards and penetrate downwards, in perfect harmony.

    After a long time, he notices that the clear light penetrates nine realms in the sky and breaks through nine realms at the bottom.

    When this step is completed, Chen Yun feels a "refreshment of the spirit."

    At this moment, he seems to have entered an extraordinary realm.

    His body seems to have disappeared.

    Something inside him seems eager to jump out.

    He knows that it's time to leave his spiritual essence!

    Chen Yun imagines the feeling of looking down from the top of the 88-floor Jinmao Tower in his previous life.

    The Jinmao Tower has a total of 88 floors, and as one ascends layer by layer, one can almost overlook the entire city.

    Chen Yun imagines himself riding an elevator up to the top floor of the Jinmao Tower, where the wind blowing from above makes him feel like he's standing on top of the world. Looking down, he sees cars below like ants.

    Suddenly, he feels dizzy and his legs feel weak.

    "That's the feeling!"

    Chen Yun knows this feeling of "chills down the spine" all too well!

    In a flash, he decides to go for it and visualizes himself jumping down from the top of the Jinmao Tower!

    Booming!

    No longer is the world the world!

    With the jump in his mind, Chen Yun feels like he's experiencing "mountains and rivers are shattered, and the earth is flat and quiet"!

    Finally... the spiritual essence has left the body!
