Now that he had judged that the potions refined by these mutated medicinal materials were harmless to his body, Liu Yu also began to wonder if he should refine some potions to improve his strength.

Also, when his body was younger, he used some potions that damaged his body, which were the potions that Dongfang Bailu gave to the original owner, harmed the original owner, and made the original owner unable to cultivate.

Now this potion has caused some hidden dangers and secret injuries to this body, and these hidden dangers and hidden injuries are the reasons why the original owner has been unable to cultivate.

Liu Yu manipulated the smart chip in his mind and conducted a comprehensive scan of this body. During the scan, this body was delicate, and he found that the major tendons and veins of this body were blocked by some black impurities, such a degree of blockage of tendons and veins, let alone cultivation, if he didn't deal with this kind of blockage, I am afraid that in another ten years, the tendons and veins of his whole body will begin to wither, and I am afraid that his life span will be greatly shortened at that time.

After the scanning, Liu Yu opened his eyes, and the cold light in his eyes flashed. He has been busy all this time, and he hasn't thought of Dongfang Bailu for a while, but now that he sees the state in his body, the shadow of Dongfang Bailu immediately appeared in his mind.

That woman, he will definitely not let it go!

But now it's not a matter of thinking about how to take revenge on Dongfang Bailu, he has to dredge the blocked tendons and veins in various parts of his body first.

It may be difficult to dredge the muscles and veins on ordinary people, but in Liu Yu's database, there are no less than ten kinds of medicines that can remove the blockages in the muscles and veins from the body.

However, not all of these more than ten potions are suitable for his current body. Liu Yu analyzed the data of this body, combined with those suitable medicines, and after comprehensive analysis, he decided to refine a medicine called 'Pulp Washing Elixir' to remove the hidden danger of congestion in the body.

The marrow cleansing potion can not only remove clogged impurities from the body, but also increase the potential of all aspects of the body, and even have a certain chance that the user will spontaneously awaken the ability.

Spontaneous Awakening is a very different concept from forcibly awakening with potions.

Abilities who spontaneously awaken their abilities will usually go further on the path of ability cultivation.

Those who use the Ability Awakening Potion to forcibly awaken the ability will often be affected by the potion because the gene chain in the body has been affected, so that the ability level cannot be increased.

Of course, this isn't absolute, but the abilities developed with potions are, in general terms, definitely not as pure as the abilities you awaken.

So, in the long time since the Awakening Elixir came out, he hadn't thought about using it himself.

And the marrow washing potion does not have all the hidden dangers of the ability awakening potion.

The marrow washing elixir, in the sixteenth-level civilization before Liu Yu, was an extremely precious elixir. This is because many of the medicinal materials used to refine the marrow cleansing potion are extinct or endangered species. But all of this is not a problem now.

He had already used his authority to check the inventory of medicinal materials in the pharmacist's office. The materials for refining the marrow washing potion happen to be in the inventory of the pharmacist's office.

It's just that the marrow washing potion is already a relatively complex potion, and I'm afraid that one person will be in a hurry to refine it, so he has to find an assistant.

As soon as he thought of his assistant, Liu Yu immediately thought of Ye Qing, he was too busy for a while, and he forgot about Ye Qing.

At that moment, Liu Yu clicked on the brain, turned out Ye Qing's contact information, and then directly sent Ye Qing a call request.

Soon, the call was connected, and Ye Qing's image appeared directly in front of Liu Yu through the three-dimensional projection function of Zhi Brain.

"Yu Shao, you finally contacted me, I thought you forgot about me!" Ye Qing's honest and slightly complaining voice came from Zhi's brain.

Liu Yu smiled and said, "I've been too busy these days, and I really forgot about your affairs." Do you have time in the future, I am short of an alchemy assistant here. ”

Hearing this, Ye Qing's face showed surprise, and he said again and again: "There is time, of course there is time, in the past few months, I am on call at any time, just waiting to be your assistant." ”

"That's a good feeling, I'm about to refine a potion, I need an assistant to help, where are you, I'll pick you up."

After the two agreed on the time and place, Liu Yu went to pick up Ye Qing, and then went to the warehouse of the pharmacist's office, received the medicinal materials needed to refine the marrow washing potion, and then drove Ye Qing back to his small building.

Before entering Xiaolou, Liu Yu told Ye Qing about Xiaolou being wrapped in a large array of potions, and gave Ye Qing a small bottle of poison-avoiding pills.

As long as Ye Qing has the pill in his mouth, he can enter and exit the small building at will without being affected by the large array of medicines.

Now, on the second floor of this small building, Liu Yu has transformed a laboratory, and he took Ye Qing directly into the laboratory, and then explained to Ye Qing the various precautions for refining the marrow washing potion.

Ye Qing has a good talent in refining potions, he didn't have the opportunity to contact potions before, but now that he was brought in by Liu Yu, Liu Yu immediately found that he had picked up a treasure, this Ye Qing, after some training, can definitely become his right-hand man.

The preparations for refining the marrow cleansing potion had been completed, and before starting the refining, Liu Yu looked directly at Ye Qing's gaze and said, "Ye Qing, since you have become my assistant, there are some things that I must also tell you clearly." ”

Seeing that Liu Yu said solemnly, Ye Qing also showed a solemn expression, listening to what Liu Yu was going to say next.

"Every pharmacist has his own secrets, and some of the potions I refine may be unheard of by you.

Even, when you step deeper and deeper into the potion industry, you will find that the potions I refine are becoming more and more mysterious, and you can be curious about it, but you must not reveal any of the potions I refine.

That's the only thing I ask of you. ”

Hearing this, Ye Qing immediately assured: "Yu Shao, don't worry, I can't do anything else, but my mouth is tight enough." ”

Liu Yu nodded, and did not delve into the truth of Ye Qing's words, the so-called Lu Yao knew that the horsepower was popular for a long time. Ye Qing is talented, but not gifted, they are all worth cultivating. Whether Ye Qing is worth his efforts to cultivate depends on Ye Qing's future performance.

The refining of the marrow washing elixir was not very smooth, because Ye Qing was a novice assistant after all, and it was inevitable that some things could not be done properly, and during the first refining, because Ye Qing handed over the wrong container, the time was delayed, resulting in the failure of the first refining.

Fortunately, Liu Yu's medicinal materials were well prepared, and he could also refine them for the second or even third and fourth times.

Because the medicinal materials were not nervous, Liu Yu was not in a hurry, and it was not until the fifth time that the marrow washing potion was successfully refined.

Looking at the about 200 ml of medicine in the Erlenmeyer flask, Ye Qing almost cried out excitedly.

"Elixir, this potion was refined by me!" Ye Qing's voice was a little choked, "Yu Shao, what kind of elixir is this, and what effect does it have?" ”
