Back in the valley, Chen Yu began to think about his current situation. What happened to Qingyunmen had little to do with him. It's just that Han Yu is nowhere to be found, which makes him a little worried. Maybe he can go to Han Qing to discuss a thing or two, or maybe this big brother knows something.

Thinking that his eldest brother was able to enter the Elite Hall in such a short period of time, Chen Yu was also very happy about it. It seems that it is necessary to find this big brother in the spare time.

There are also things that Han Yuanxing instructed the three of them, and they can only be decided after discussing with Han Qing. After all, Han Yuanxing did not hesitate to offend Li Yuancheng, but also wanted to protect him, Chen Yu is not a person who does not repay his kindness.

But today, Chen Yu has other plans.

When he was flipping through Hai Lao's medical book before, he saw the formulas of several medicines mentioned in the letter that Hai Lao left before leaving. It also happened to be the several medicines he needed at this time, including some antidote and healing for internal and external injuries.

These are all things that Chen Yu has always wanted to match but have not matched, first, he has no medicinal materials, and secondly, he has no time.

But now, with the mysterious liquid of the gourd that can give birth to medicinal herbs, there will be no sectarian trivia to disturb him if he stays in the Holy Hand Valley all the time.

Chen Yu calculated the time, at this time, there was still at least half a year before Hai Lao came back, so he had enough time to prepare the medicine he needed. Therefore, Chen Yu secretly decided that before Hai Lao came back, he would try his best to give birth to and configure some of the medicines he needed the most, and give full play to the gourd green liquid he had.

First of all, Chen Yu wanted to configure medicines that would help him cultivate mantras, increase his strength, and break through bottlenecks. Most of them are the best holy medicines that Hai Lao wanted to configure before, but he has been short of medicinal materials. If each of them is placed outside, no one who sees it will be blushing. and has become the object that everyone will fight for at any cost.

It is said that Hai Lao is such a clever medical book, and he has only seen a few of them. And the rest, however, have a formula but no medicinal materials, and Hai Lao can only look up to the sky and sigh helplessly.

Chen Yu and Wang Mu had studied medicine with Hai Lao before, and they were extremely interested in these formulas. However, Wang Mu didn't dare to compliment, and he couldn't arouse the slightest interest. Hai Lao did not force the two of them from beginning to end, nor did he have the slightest intention of hiding his selfishness from Chen Yu, and he also solved his doubts one by one. Sometimes, Hai Lao was even very happy that Chen Yu liked medical skills.

Maybe Hai Lao also thinks that these formulas are tasteless and it's a pity, or maybe he really wants to pass on his medical books. Or often urge Chen Yu to practice mantras and let him relax for a moment or two.

But now for Chen Yu, this is simply his baby bump. He began to give birth to the required medicinal materials one by one according to the recipe, and did not dare to be sloppy in the slightest. After all, he is dispensing medicine for himself, and if there is a fork, he is the only one in the valley, and he is obviously forcing himself to think of himself. Maybe after death, there is no one to collect the body, only to wait for Hai Lao to come back. Presumably he was already stinky at that time, Chen Yu didn't dare to think about it anymore.

Chen Yu understood that there was not a lot of time left for him. He had to prepare the medicine he needed before Hai Lao returned. Then wrap the gourd thoroughly and carry it with you and no longer use it.

He really couldn't guarantee that if there was still one person in the small valley, he would still be able to use the gourd without being discovered. What's more, that person is an experienced sea elder in the rivers and lakes.

Chen Yu felt that Hai Lao was very strange, from the beginning of seeing Hai Lao, until the beginning of the nameless formula. Before Hai Lao left, he felt that Hai Lao seemed to be like two people. Especially when teaching medical books to him, he looks amiable, but when he usually meets, he always feels very cold. There is another strange thing for Chen Yu, that is, unless necessary, Hai Lao is never on the floor at night.

All of this made Chen Yu feel alienated from Hai Lao. Maybe in Qingyunmen, their master-apprentice relationship is also unique.

It is said that Hai Lao is also good to him, not only teaching him medical skills without reservation. On the other hand, he was willing to use the precious medicine he had treasured for many years to assist his cultivation, and he even saved his life at a critical moment.

What's more, in his usual cultivation, in addition to urging him to be diligent, Hai Lao has not punched or kicked, and he has almost no insults. And Hai Lao seems to have been giving, but perhaps it is this excessive giving, as well as what Hai Lao usually shows, that has created a layer of separation between Chen Yu and Hai Lao. Every time they met, Chen Yu felt very embarrassed.

However, while Chen Yu's mantra continued to improve, the estrangement between him and Hai Lao also became stronger. He vaguely felt that Hai Lao had a very strong intention towards him, and he had been hiding it very deeply. Every time I look at my eyes, in addition to scrutiny and appreciation, there seems to be a little more coveting. Under such circumstances, Chen Yu did not dare to take the risk of letting Hai Lao discover the secret of his gourd.

Chen Yu felt that he didn't mind being filial to Teacher Hai, and if he didn't hurt himself, he could help the other party do something. But if Hai Lao is not good for him, maybe he can only protect himself, Chen Yu even feels that he is too suspicious.

But Chen Yu knows that the heart of harming people is indispensable, and the heart of preventing people is indispensable. There is only one life, he can't help but be vigilant, the only thing he can do is to hope that he has more heart. Thinking of this, Chen Yu's heart was full of discomfort.

In short, Chen Yu made up his mind, and in order to keep the secret, he vowed never to use his gourd lightly again. His heart was a little wider, and Chen Yu suddenly felt a little tired, so he fell asleep.

For the next few months, Chen Yu spent a small amount of time every day practicing mantras. The rest of the time is spent giving birth to all kinds of precious medicinal herbs that he needs, and then preparing the elixir according to the recipe.

In the configuration process, the frequent failures made him really painful for a long time. After all, there are so many precious medicinal materials, which one is placed outside, and it is not a priceless existence. But now there are not many destroyed in his hands, and Chen Yu estimates that he can support an army of his own until he is a hundred years old.

However, Chen Yu himself can't be blamed, the pharmacies configured with these precious medicinal materials are also extremely difficult to configure, and it is always normal to fail at first. Fortunately, Chen Yu can give birth to medicinal materials, and it is forgivable to miss a few times. In Hai Lao, maybe the situation is similar, Chen Yu can only give himself some relief.

......

"Bailingsan", "Yuyuan Dan", "Chalcedony Pill" and the "Yangjing Dan" configured by Chen Yu before. These are all rare medicines from the outside world, and they are all placed in dozens of small medicine bottles in front of Chen Yu. Chen Yu looked at these small medicine bottles, and his heart was excited. With these pills, he would no longer have to worry about the cultivation of mantras. At least the sixth, seventh, and even eighth layers he can try.

Among these medicines, "Bailingsan" is a kind of antidote holy medicine, except for talking about several kinds of poisons in the world, the rest are not a problem. And "Yuyuan Dan" is a kind of medicine for internal and external injuries. No matter how many internal and external injuries are inflicted, as long as you take one pill, the injury can be greatly reduced and your life can be saved.

And the "Chalcedony Pill" and the "Nourishing Essence Pill" are both used by Chen Yu to cultivate the mantra at this time. It has a miraculous effect on increasing its power and breaking through bottlenecks. Chen Yu had already tried the effect of the "Nourishing Essence Pill", and the medicinal effect of the "Chalcedony Pill" could only be used after the sixth layer of his formula.

In addition, Chen Yu also equipped some additional "Yu Ling San", this kind of traumatic fast-acting medicine can also be used by himself, and it should be good to use it to give Han Qing and Hai Hanyu some more. As for "Yuyuan Dan", the cost is too high, and Chen Yu is reluctant to use it until the critical moment.
