Yue Yu had been fighting this kind of spirit pill for a long time. After all, being able to directly improve his cultivation was still very tempting for him, and of course, Yue Yu also knew very well about the harm.

But unfortunately, even the cheapest of these spirit pills cost one hundred and fifty taels of silver. And Yue Yu's monthly monthly silver is only about two and a half now, which sounds a lot more than Ran Li. It's a pity that this big man still has a hundred acres of land left by his parents, and now Yue Zhang's family is taking care of him. In addition to saving some money every year as a bride price for future marriage, some of it fell directly into Ran Li's bag. Therefore, their private money is half a catty and eight taels. If he really used all this money to buy spirit pills, then Yue Yu wouldn't have to do anything else.

So originally, Yue Yu planned to start this matter again after the year. However, because of the previous incident, the pharmacy he expected started operating months ahead of schedule. And for the study of this spirit pill, it was accordingly a little earlier.

-- The so-called loss of the horse is not a blessing. Although this caused Jin Xu's group to be more impatient, it also gave him the opportunity to contact these spirit pills early.

In order to enrich the variety of medicines in the store, Yue Zhang's family invested a lot of money to buy some elixirs that were not within the scope of the clan's monopoly, and this elixir was also among them. And such an opportunity, Yue Yu naturally refused to let go. Soon after he bought it, he secretly made a detailed analysis of its ingredients.

The most important ingredient is naturally the crystallization of demonic power, which is similar to the structure of Peiyuan Pill, which is wrapped in some auxiliary drugs, which can re-induce the crystallized demonic qi after falling into the stomach, make it disperse, and help the human body absorb it. In addition, some of these auxiliary drugs also have the effect of neutralizing those demonic true elements.

And Yue Yu guessed that the reason why this spirit pill had drawbacks was that the spiritual power contained in it was chaotic, and there were not many demon beasts that belonged to the surname alone. In fact, even a beast of the level of the Wind Wing Xuanhu had nothing but wind aura in its body. Among them, the fire aura is in second place, and there are many other caste spirits mixed in the middle.

In addition, the spiritual power content in each person's body is also different, you must know that even if it is an innate powerhouse, it is impossible to completely expel the spiritual energy of other castes, and you can only try your best to strengthen the strength of a certain spiritual power.

This makes those pharmacists who are trying to improve the spirit pill aware of this problem to a certain extent, but they are helpless.

- Because of each piece of demonic power crystal, everyone's true qi composition is different. They may be able to change the composition of the medicine of the spirit pill to a certain extent according to the conditions of the person and the material, but they cannot achieve its popularization.

However, this is no problem for Yue Yu at all. Distinguishing the spiritual energy content in a piece of demonic power crystal, an innate pharmacist can do it. And his current internal breath cultivation is only level five, but he has a tool that far surpasses this era in terms of material composition analysis.

Of course, this does not mean that Yue Yu can absorb these demonic power crystals without any scruples. In fact, the confusion of spiritual power is only one of the troubles. The most headache is also the heterogeneous true element in the demon power crystal, which is essentially similar to the true element of the human body, but it is very different in terms of surname quality and composition. Human beings can absorb it, but the true qi of their own body will inevitably be mixed and impure.

In this regard, even those top pharmacists have no way to think about it. Those congenital-level pharmacists, although they can also sense the existence of various spiritual powers, are far from being able to thoroughly understand the most fundamental things such as demon beasts and human body true elements, and there are no other suitable medicines that can change their surnames.

This was originally an unsolvable problem, and Yue Yu himself had no choice but to start re-researching it without a precedent to follow. But since he learned that all the people who use the spirit pill, as long as they take an appropriate amount, although it is difficult to make any progress in their cultivation after that, there is basically no phenomenon of losing control of their true qi or going mad;

It's a pity that Yue Yu doesn't have any substantial evidence in his hand to prove this. Recently, among the several martial artists hired by his family, there were one or two, who relied on the help of Lingmaru to forcibly raise their strength to the realm of martial artists. However, the problem is that his analytical ability needs to be fed into the other party's body to be able to complete it. If it weren't for the fact that Ran Li and the servants in his family were either deeply connected, or they couldn't resist. I'm afraid that there are rare people, who will rest assured that he will input the internal breath into his body and toss. What's more, his current fifth-level Great Chaos True Qi can't be exposed.

However, this did not prevent Yue Yu from developing the spirit pill, and the unicorn civet brought back this time had a rare five elements in its demonic power crystal. Yue Yu only needed to purify and delete the spiritual power content in his body according to the proportion of the spiritual energy in his body, which was enough to create a demonic power crystallization suitable for him.

At this point, it would have been possible to absorb it directly. However, those pharmacists in the Dongsheng Continent were not vegetarians after all, and they couldn't completely find a perfect solution to the Demon Power True Yuan. However, after thousands of attempts, it has also been found that some drugs can reduce the violent and uncontrollable special surname of the demonic true element to a certain extent.

In addition, considering that there were also some medicinal ingredients in it, which could help the human body completely absorb the demonic power, Yue Yu finally decided to use these demonic power crystals in the form of pills.

As for the process of refining medicine, it was even simpler than Peiyuan Pill. This thing is not very useful, so the prescriptions of various spirit pills are extremely widespread, and Yue Yu only took a few days to completely master it, and even on this basis, he has made some small improvements.

And at this moment, the three pills named by Yue Yu as the Five Elements Spirit Pill were spinning in the bronze tripod in front of him. The colorful colors exude this burst of medicinal fragrance. However, looking at these nine spirit pills, Yue Yu was a little distressed. Although he was excited and looking forward to it, he was also worried that he had misguessed.

Shaking his head, Yue Yu shifted his gaze to the left, and beside the Five Elements Spirit Pill, there were two small red and yellow pills. This is what he prepared for Ran Li, the surname of the Xuanwu Turtle is earth, and in addition to the wind spiritual power, there are also nearly thirty percent of the fire spiritual power in the surname of the Wind Wing Xuanhu. Combine these two, so there are these two dust spirit pills. Of course, they are also untested. But this time, I can't say it, it's to let this big man act as a white mouse for a while.

The corners of his lips lifted up slightly, and Yue Yu turned his head in Ran Li's direction: "Ah Li, please come here!"

Ran Li was facing a pine tree, sweating profusely and wielding an axe, trying to chop down the fallen pine needles. However, the axe wind around him was agitating at the moment, and often before the axe blade arrived, the target had already drifted farther away under the strong wind. In fact, only a few dozen pine needles were cut in half a day, and most of them were unlucky and crashed into them.

- This may seem stupid, but Ran Li did it for a reason.

About a month ago, he had seen Yue Yu practice swordsmanship once, and at that time, his little master, was also standing under a pine tree. The massive number of pine needles that fell were not missed, and they were evenly cut into four pieces from the vertical axis.

And Ran Li, who saw this scene at that time, was shocked, but he didn't really take it to heart. However, in the battle a few days ago, when he saw with his own eyes that Yue Youshun couldn't capture Yue Yu's figure and sword no matter what, and his huge internal breath couldn't play a role at all, he was really shocked.

In Ran Li's mind, if he could practice half of Yue Yu's ability, maybe the more two-order challenges would not be a problem.

However, for seven consecutive days, Ran Li was so restless that he couldn't figure out the way at all. So when he heard Yue Yu's call, Ran Li was inexplicably surprised, thinking that Yue Yu finally couldn't see it, and wanted to point him out. However, when he turned around, he saw that his little master's face was full of warm smiles.

Ran Li couldn't help but shudder, with what he knew about Yue Yu these days, it was absolutely nothing good when he usually showed this kind of smile!
