Chu Yun took the two girls back to Qingyue Mountain Residence, and the first thing he did was to lock himself in the alchemy room, and at the same time instructed Yu'er and Xishuang not to let anyone disturb him.

With his identity in the Dan Medical Hall, as long as he said so, even if he came over, it was estimated that he would only wait outside, and he didn't have to worry about making any trouble.

Chu Yun was ready to immediately start refining the Pulse Washing and Changing Pill.

In the past, he had already gathered all the medicinal materials for the Pulse Washing and Changing Pills in batches, and now the last auxiliary medicine has also arrived, and the refining medicine is already ready.

This Pulse Washing Pill is a level 8 pill, and it is the most difficult of the level 8 pills to refine, and its refining difficulty is close to that of a level 9 pill.

This is definitely the most difficult pill that Chu Yun has refined since he came to this world, although the level of the Heaven Snatching Pill he refined before has reached level 9, but the Heaven Snatching Pill is a pill created by Chu Yun, Chu Yun has a unique advantage when refining this pill, and its difficulty is similar to that of four or five pills. Otherwise, it would be absolutely impossible for Chu Yun to refine the Heaven Snatching Pill without any internal force cultivation.

The Pill of Washing the Pulse and Changing the Marrow is different, it is an elixir with inherent refining techniques, and each of its techniques is not tailored for Chu Yun, so the difficulty of refining it will naturally double.

Fortunately, now Chu Yun already has the strength of the late stage of the Acupoint Realm, and the degree of internal strength can be completely compared to the peak of the Acupoint Realm, coupled with his extremely high alchemy skills and the experience of refining the Pulse Changing Pill last time, he believes that there is no problem with his refining this time.

Chu Yun opened the alchemy furnace as if he was in the mood of a pilgrimage, and then put the initial auxiliary medicine into it.

Ignition ......

All the herbs begin to change gradually under the calcination of the furnace fire, the herbs begin to dry out, and impurities are gradually removed.

Immediately after that, some auxiliary drugs were put in, and these herbs quickly melted and mixed with the original powder, gradually forming a layer of black-brown viscous liquid......

The alchemy process continued, and Chu Yun strived to be perfect in every step.

When the last main medicine, the 10,000-year-old chalcedony, was put in, the entire alchemy furnace erupted into a huge vibration.

Chu Yun's expression was serious, it was not that there was a problem with the alchemy, but that these pills contained huge energy, and they were in the final step of the process.

Ning Dan!

Combine the essence of the elixir with the strange energy to form a round elixir.

Chu Yun pressed his palms against the alchemy furnace, almost uncontrollably transmitting internal force into the alchemy furnace.

And with the gradual consumption of Chu Yun's internal force, the vibration of the alchemy furnace was also slowly weakening.

When he gritted his teeth and transported the last wisp of internal force in, the alchemy furnace completely stopped, and Chu Yun let out a long sigh of relief, with a relieved smile on his face.

"Perfect!" Chu Yun couldn't help but admire himself a little.

This alchemy, he has already carried out countless simulations in his heart, and it can be said that he strives for perfection.

Including the total amount of internal force, the weight of the pill, and how much internal force needs to be used at each node......

In fact, with Chu Yun's situation, even if his internal strength is lower, he can still refine the Pulse Washing and Changing Essence Pill, but it will not be perfect, and it is impossible to condense all the medicinal materials and spiritual energy into the pill, that is to say, the final harvest will inevitably be less.

Chu Yun stood up, although his body was endlessly tired, but his mind was extremely excited.

How many pills can be refined? Chu Yun didn't know the bottom in his heart, this was related to the improvement of his qualifications, so he couldn't help but be nervous.

Almost at the same moment, a system prompt sounded in Chu Yun's ears:

"System prompt: Successfully refine six level 8 pills to wash the pulse and change the myelin pills, and reward 4800 points of skill experience.

Chu Yun unveiled the alchemy furnace, and when he saw that there were indeed six Pulse Washing and Changing Pill lying quietly inside, he finally let out a long breath.

"The system really doesn't deceive people." Chu Yun muttered.

With these six Pulse Washing and Changing Pills, Chu Yun's future will be different.

Although there were even heavenly and earthly treasures in this world that directly improved their qualifications, Chu Yun didn't feel that he had such good luck to get such a treasure again. Even if it was the same 10,000-year-old chalcedony, Chu Yun didn't dare to guarantee that he would definitely be able to get such a few more drops.

Three drops of 10,000-year-old chalcedony were exchanged for six pulse-washing pills.

Chu Yun was glad for his wise choice at the beginning, if he had wanted to take credit in front of the Great Gate Sect at that time, or for the so-called punishment of adultery and elimination of evil, I am afraid that these three drops of 10,000-year-old chalcedony would have missed him.

It's just that I don't know what kind of mood the Wanqing girl will have when she learns that she has successfully refined the Pulse Washing and Changing Pill.

The value of the six Pulse Washing and Changing Pill will not be lower than that of the Nine Yin True Scriptures. The Nine Yin True Scripture mentioned here is not the deleted version, but the original version.

At that moment, Chu Yun put away the six Pulse Washing and Changing Pill with an extremely fast technique and put them into a small jade bottle.

Chu Yun did not leave the alchemy room directly, but instead sat down, poured out a pill from the jade bottle, and gently put it in his mouth.

The pill melted in his mouth, and a refreshing fragrance flooded all of Chu Yun's senses.

Immediately after that, Chu Yun felt something explode in his chest and abdomen, and the violent energy began to wash over his body.

The meridians, acupuncture points, muscles, bones, everything is tempered together under this energy.

Finally, that energy was consumed, and Chu Yun felt that he didn't seem to have changed much, but there seemed to be something more.

Chu Yun was excited, and called up his attribute panel, and suddenly found that the root bone value on it had become 6 points.

Finally getting the root bone to the best level, Chu Yun was extremely excited in his heart.

Now there were five pills left, and Chu Yun decided to continue taking them without any hesitation.

A pill went down to his stomach and continued the process just now, but the reaction was much weaker.

After the effect of the medicine dissipated, Chu Yun did not directly increase the root bone value as expected.

Another elixir......

Another elixir......

When all the medicinal effects of the fourth Pulse Cleansing Pill were absorbed, Chu Yun finally saw that his root bone value had increased to 7 points.

Once in a century! The root bone has finally reached a once-in-a-century level.

In the future, the experience points I gained in cultivation were finally no longer dispensable. Although it is not as good as Yu'er and Xishuang, and even less than Dongfang Zhuo, this is also a lot of progress, isn't it?

Of course, the most important point is that if you treat the disease and refine the pill in the future, the experience points you will gain will be directly increased by 9 times, which is a real benefit. If he had 7 points of bone before refining the Pulse Washing and Changing Pill, the experience points obtained from the alchemy just now would have reached an astonishing 43,200 points, which was equivalent to the effect of most of the Yuan Spirit Pill.

Although the amount of experience gained from alchemy is somewhat limited, it is also an astronomical amount, which is enough to push one's strength to a very high height.

Chu Yun had the urge to immediately refine a furnace of pills to verify the thoughts in his heart, but in the end he held back.

Now he still has a pulse washing pill left in his hand, which is undoubtedly a priceless treasure.

But to himself, this thing is no longer of much use, even if the number reaches twenty or thirty, it is impossible to raise his root bone to 8 points. If you want to continue to improve the root bone in the future, you have to think of other ways.

Regarding how to dispose of this Pulse Washing and Changing Pill, Chu Yun didn't have a better idea for the time being, because it had a limit on its use, and the upper limit of its Root Bone Enhancement was 9 points. In other words, this pill is useless to Yu'er or Xishuang and others.

So who is this Pulse Washing Pill for? Own parents?

Their root bones have only reached the best level, and even if they use this marrow cleansing pill, they will increase to 7 points at most, which is the level of once in a hundred years, which is relatively speaking, and they will not be able to give full play to the maximum value of the elixir. Instead of this, it is better to get them more pills to increase their internal strength cultivation, so that although their actual combat effectiveness will be worse, their cultivation realm will still be improved, and there will be no difference in terms of prolonging life.

After thinking about it, Chu Yun finally decided to let Liu Lao take this Pulse Washing and Changing Pill.

After these days of getting along, Chu Yun also knows Liu Lao's temperament very well, and he has no doubt about his loyalty. Moreover, Liu Lao has been walking the rivers and lakes for many years, and he is extremely experienced and very experienced in handling things, so he will definitely be able to help him deal with many things in the future.

Although Liu Lao's current qualification is only at the level of once in a century, the root bone value is 8 points, which is just suitable for using the pulse washing pill.

For Chu Yun, what he lacked most was not these resources that could improve his strength and qualifications, but people, a loyal person, a person worthy of cultivating with precious resources.

Obviously, Liu Lao meets this criterion very well.

Putting away the jade bottle that only had one left to wash the pulse and change the myelin pill, Chu Yun walked out of the alchemy room.

When they arrived outside the door, Chu Yun saw Yu'er and Xishuang standing there, and in front of them stood an old man, who was suddenly Chu Yuanshan.

It seems that He Zheng has already informed Chu Yuanshan of the news of his return, and since he has spent two or three months in the house alchemy, it is estimated that Chu Yuanshan has come here early to wait.

It's just that because he has his own orders, Chu Yuanshan doesn't dare to break through, otherwise, with the strength of Yu'er and Xishuang, how can he stop Chu Yuanshan?

"Senior brother, you're really fast." Chu Yun was in a good mood because of his improved qualifications, and he couldn't help but tease.

Chu Yuanshan also saw Chu Yun come out, and immediately greeted him, saying, "Senior brother, you can be regarded as back, there was a problem in alchemy that tortured me for a few days a few days ago, and I haven't found a solution." If I had done it before, I would have been able to calm down and study and explore, but now I know that you have a way to solve it, junior brother, and I don't have the heart to test and verify it, tell me quickly, why I can't completely refine the medicinal properties of the medicinal materials when refining the Yuan Ling Pill? ”
