Although successfully combining the "8 and 9 Supreme Skills" with the "Heaven and Earth Spiritual Qi Refining Spiritual Skills" is theoretically feasible, Chen Yun knows that this is only a preliminary plan. She needs to try several more times in the future, find out what errors exist, and then figure out how to correct them.

    "I wish to integrate all that I have learned into 'Mr. Chen's Inner Alchemy Mantra'."

    Chen Yun would like to include these things, but the "refining essence into Qi" part is already very perfect and she has also cultivated to the level of nearly a medium-grade mage according to her own created "Mr. Chen's Inner Alchemy Mantra." If she modifies the exercise in the middle, who knows what kind of trouble might arise?

    So he thought that these things could only be added to subsequent techniques, that is, after refining out the Golden Dan.

    "Right, during the previous outbreak of Tao Qi, my True Qi was consumed, and now I need to first restore my True Qi before saying goodbye to Xie Zhenren."

    Thinking of it, Chen Yun poured a basin of water and quickly heated it with firepower, taking a hot shower.

    As he bathed, Chen Yun pondered silently, "Long before these past few days, my True Qi quantity had already reached the late stage of a six-star mage, just a step away from becoming a medium-grade mage. It seems that I could break through to the level of a medium-grade mage in just a few days, but that is not the case at all."

    Chen Yun had observed her True Qi before.

    During these few days, the effect of "refining essence into Qi" has made her True Qi full and reached the critical point of breakthrough. However, because she had eaten Lingqi to accelerate growth before, it was difficult for her True Qi to condense into tangible form and display a "poor quality".

    This is the drawback of relying on external objects.

    Although Lingqi can quickly improve one's cultivation, it is ultimately not something one gains through self-training.

    "The essence refining and Qi generating soup is indeed an external substance. It does automatically run along the path of practicing 'Mr. Chen's Inner Alchemy Mantra', and it doesn't seem to be one's own cultivation, but in reality, it's no different from normal cultivation. The True Qi produced has no quality issues."

    Comparing Lingqi with the essence refining and Qi generating soup, Chen Yun immediately realized how miraculous the latter was.

    However, he sighed immediately, "Based on the current progress, I think it will take me about a month to cultivate to the level of a medium-grade mage. If I calculate the days, I might not be able to do so until after the New Year."

    If it were under normal circumstances, Chen Yun wouldn't have sighed so much even if her cultivation speed was slower.

    It's just that before, after being ambushed and assassinated by Yin Wuji, he had been holding a grudge in his heart, eager to take revenge.

    Yin Wuji was indeed too strong, with the initial strength of an upper-tier mage.

    Chen Yun now has some hope of winning with the help of her treasure and magical weapons, but it's still not very reliable.

    He believes that in order to achieve a decisive victory against Yin Wuji with absolute certainty, at the very least he needs to cultivate his True Qi to the level of a medium-grade mage and make a detailed plan, which would give him hope of defeating the other party.

    "Let him live a little longer first. When my True Qi is cultivated to the level of a medium-grade mage, I will settle the score properly!"

    After finishing his bath and dressing, Chen Yun checked to make sure all the doors and windows were properly closed.

    Confirming everything was in order, he lit three sticks of incense to help himself concentrate and calm his mind.

    After completing all these steps, Chen Yun returned to the bed, sat cross-legged, and practiced to restore her True Qi.

    According to the path of exercises in 'Mr. Chen's Inner Alchemy Mantra', Chen Yun practiced and her True Qi was slowly restored.

    At first, Chen Yun didn't notice anything wrong, but as his True Qi restored more and more, he gradually discovered a subtle anomaly.

    The True Qi seemed to have become more condensed!

    "Hmm?" Chen Yun was startled and paused his exercise to restore True Qi. He had some doubts and muttered to himself, "I didn't practice yesterday, but the essence refining and Qi generating soup automatically generates True Qi at midnight. I didn't notice that the True Qi became more solid back then. Why is it that restoring True Qi today feels so heavy?"

    He thought it was an illusion.

    Uncertain and hesitating, Chen Yun pushed aside all distractions and used "sight of the mind" to observe the True Qi within his own body.

    Looking wouldn't have been so bad.

    Upon seeing it, he was stunned in disbelief.

    If the original True Qi was like "gas," then now it was advancing towards becoming "liquid."

    Of course, True Qi is intangible and has no substance, but it is still very real. The "mind" can see its form.

    Chen Yun was quite certain that he saw a tiny bit of transformation in the True Qi when he used "sight of the mind" to observe it.

    Although the True Qi had only undergone a tiny transformation, it seemed like a small progress, but in reality, due to the poor quality of True Qi caused by taking Lingqi, it was necessary to rely on the essence refining and Qi generating soup and diligently practice for over a month to achieve this.

    Without the essence refining and Qi generating soup, it might take two or three years to achieve.

    Now?

    After going out to fight, has the True Qi become condensed?

    Chen Yun really couldn't figure out what was going on.

    But he knew there had to be a reason, otherwise the True Qi wouldn't have become condensed and thick without any reason.

    Suddenly, he remembered that before the outbreak of Tao Qi, his body was constantly compressed by Gong Juchi's "energy wall." At that time, he kept calling on True Qi to break through the other party's encirclement, but he couldn't mobilize it, and was continuously compressed by Gong Juchi's powerful force without realizing it.

    "Could it be that Gong Juchi compressed and solidified my True Qi?"

    Chen Yun felt that there was a possibility, but it should not be just one reason.

    As he carefully recalled the Tao Qi outbreak, the powerful force inside him swept through, trying to shatter his invincible body into fine powder, unable to withstand it. In order to suppress it, he called on True Qi to do so, but it couldn't do so and was instead washed away countless times by Tao Qi.

    Could that be the reason too?

    Chen Yun thought it was highly possible. Because in terms of energy attributes, Tao Qi must be far more advanced than True Qi. As Tao Qi pushed the True Qi back into the lower dantian, and even if it wanted to shatter his entire body, including his dantian, it naturally exerted a huge compression on the True Qi, thus causing a trace of qualitative change in the True Qi.

    It was both external pressure and internal Tao Qi erosion that caused the True Qi to become solid and heavy all at once.

    It should be these two reasons.

    Otherwise, why would his body have been damaged by Gong Juchi and Tao Qi to the extent that his True Qi was depleted?

    "It should not just be the quality of True Qi that has changed. If Tao Qi has swept through every part of my body, the yin god should also have undergone some changes."

    Chen Yun can simply check the status of his yin god to know whether his guess is correct.

    He didn't hesitate to send his yin god out of the body.

    In an instant, he saw that his yin god had shrunk quite a bit, but its strength was more concentrated.

    "Indeed!" Chen Yun finally confirmed it completely, "Indeed, it was the outbreak of Tao Qi that swept through my body, causing the qualitative change in my True Qi!"

    He couldn't help feeling a sense of joy.

    In this way, he could at least save himself the trouble of hard work for over a month!

    Chen Yun brought his yin god back into his body, sat there and pondered silently, "Since the True Qi has become condensed, then I can now attempt to break through to the level of a medium-grade mage!"

    Without hesitation, he quickly practiced to restore his True Qi to its peak.

    Then, without caring whether Xie Ziran had chased him away, Chen Yun lay down on the bed and slept.

    He needed to ensure that he could successfully break through to the level of a medium-grade mage when the essence refining and Qi generating soup's medicinal power emerged at night.

    ...

    He slept until just before midnight.

    After waking up, Chen Yun drank some clear water and then used the method of the "Flying Spirit Jade Token" to absorb some spiritual Qi from the heavens and earth to maintain his physical vitality.

    Then, he adjusted his state to the best.

    Chen Yun sat cross-legged and waited for the medicinal power to emerge.

    As expected, the moment midnight struck, the medicinal power of the essence refining and Qi generating soup that he had taken earlier began to slowly rise.

    "I will attempt to breakthrough to the level of a medium-grade mage tonight!"

    Chen Yun had the determination to either succeed or perish trying.

    A surge of heat began to rise, moving towards the spleen.

    In an instant, clusters of spiritual energy began to emit from the spleen.

    These spiritual energies split into two streams, rising along the left and right sun meridian, flowing from the bottom of the big teeth up to the temple, and then entering the Mudan Palace.

    According to normal cultivation practices, at this point, one should open their eyes and then close them to concentrate on their mind after a while.

    Just that Chen Yun didn't need to actively practice, so it was unnecessary to go through all that trouble.

    When this Qi reached the Mudan Palace, it slowly flowed into the brain and then descended the twelve loops of Chongliu, through the spine, through the Dazhui to the top, entering the heart and penetrating the liver.

    Chen Yun felt a warmth in his heart. First, there was a slight bitterness in his mouth, and then the Jinyin Yujue (gold and jade fluid) was produced.

    Chen Yun slowly swallowed the sweet dew, and the True Qi gradually flowed into the lower dantian.

    The situation of enhanced spirit once again occurred.

    Chen Yun knew that with each of his practices, that "god" within him was growing stronger, and he did not pay too much attention to it.

    Chen Yun found that the True Qi generated by the medicinal power today seemed a bit abnormal.

    "The amount of True Qi generated seems to have decreased."

    Chen Yun knew it was just an illusion, "The amount of True Qi generated has not decreased. My True Qi has undergone a qualitative change. If it used to take one part of the medicinal power to generate a strand of True Qi, now it would take about seven-eight parts to generate a strand of True Qi, so it feels that the amount of True Qi generated has decreased."

    He has a clear mind like a mirror.

    These thoughts flashed through his mind like a mirror, and Chen Yun continued to feel the refined True Qi.

    As the refinement of the medicinal power continued, time passed slowly and steadily.

    A small circuit of the cosmos.

    Three small circuits of the cosmos.

    A sub-time passed quickly, and nine small circuits of the cosmos ended.

    In the lower dantian, there was a subtle sensation of ongoing qualitative change in the True Qi.

    However, the medicinal effect of the essence refining and Qi generating soup has passed today, and it seems unlikely to generate True Qi again.

    Chen Yun, with a determined stance, disregarding whether his body could withstand it, directly activated the "Mr. Chen's Internal Elixir Formula."

    One after another, True Qi emerged.

    He didn't know if it was because of the strengthened physical body, but he felt that the amount of True Qi generated from his active cultivation was almost half that of the essence refining and Qi generating soup.

    "The body has become strong, so the spiritual Qi within it is naturally more abundant, leading to the generation of more True Qi."

    Chen Yun understood roughly what the cause was and didn't dwell on it.

    He put aside all distractions and concentrated entirely on his cultivation.

    ...

    Time passed day by day.

    One day.

    Three days.

    Five days.

    Dedicated to cultivation, Chen Yun didn't count how many days had passed, only knowing that the medicinal power of the essence refining and Qi generating soup from yesterday had ceased to be born, and his body was close to its limit due to continuous practice for several days.

    If he still couldn't break through, he would have to stop and brew another batch of the essence refining and Qi generating soup.

    However, what is pleasing is that after Chen Yun had just generated another strand of True Qi, the True Qi within his lower dantian underwent a complete qualitative change!

    Huffing and puffing!

    Suddenly, a violent gale swept through the tightly closed room.

    Chen Yun felt the True Qi surging and actively released it outside of his body.

    At first, the True Qi wandered around the room like it was easy to command. However, Chen Yun noticed that the True Qi didn't dissipate even after lingering in the air for a while. He controlled the True Qi to penetrate through the gaps in doors and windows and slowly spread outward.

    One mile.

    Three miles.

    Five miles.

    The True Qi spread out for several miles before gradually dissipating.

    This wasn't the most surprising thing to Chen Yun.

    The most surprising thing to Chen Yun was that after the True Qi was dispersed, he could clearly see the shape of objects enveloped by True Qi, as if his mind's eye had manifested.

    "This... is the mystery of cultivating to the level of a medium-grade mage through internal alchemy?"

    Chen Yun was somewhat incredulous, the True Qi not only could spread out for several miles but also could see everything covered as if it was a mind's eye.

    The surging of such boundless power within the body is truly captivating!
