Even the most basic chemical combination agent can be ranked among the intermediate drugs in Liu Yu's pharmacy database. Naturally, the refining of chemical agents is much more difficult than that of elemental agents.

The elixir that Liu Yu is refining now is called the Light of Purification, and although this Light of Purification is among the ranks of intermediate elixirs in Liu Yu's database, its practicality and actual combat are the highest level of potions that Liu Yu can refine at present.

The Elixir of Purifying Light was originally created by a Holy See apothecary of a certain civilization and was specifically used to deal with heretical forces. The Purifying Light has a pervasive effect, and even a fully enclosed protective suit cannot stop the Purifying Light from exerting its medicinal effects.

And the medicinal effect of the Purifying Light, it is a potion that can purify all powers, including abilities and the internal power of the body cultivator. Moreover, even an S-class powerhouse can't resist the medicinal effect of the Purifying Light!

Liu Yu quietly looked at the five potions of different colors in front of him, and began to regulate his breathing and his current state. The Purifying Light Elixir can be said to be the most difficult potion he has refined when he came to the planet Kalan. Even now, he is not sure that he will be able to refine it at one time.

However, he had long been prepared not to succeed at one time, and the five elixirs in front of him, each of which was enough for him to try refining five times.

Liu Yu took a deep breath, then divided the five potions in the flask into five parts evenly, and then he started his first attempt.

In the process of refining medicine, Liu Yu's expression was extremely focused, and every movement was extremely beautiful. I saw Liu Yu quickly pour three of the five kinds of potions into a larger test tube. The three agents are not compatible in the test tube, but are clearly divided into three layers in the test tube.

Then, Liu Yu carefully added two medicinal materials and a solution to the test tube, and then the liquid medicine in the test tube changed. Although the three potions were still distinct, their respective volumes began to expand.

When the agent swelled to the point that it was about to overflow the mouth of the test tube, Liu Yuchao added a black powdered catalyst to the test tube. The swelling potion instantly converged a little, but after a while, it came back and continued to expand. Liu Yu added the black powder catalyst again, and repeated this six times, and the state of the medicine finally stabilized.

After the state of the medicine stabilized, the original three-layer solution in the test tube had been mixed together with Liu Yu's gentle shaking action, but the liquid medicine was no longer clear, but turned into a blue-black turbid liquid that looked a little seeping.

Liu Yu looked at the turbid liquid in the test tube, and then sighed, the first refining failed. These six times of adding the catalyst is the first difficulty in the whole refining process, if successful, the medicine in the test tube will turn into a clear and slightly transparent blue-black liquid.

And now, what Liu Yu got was blue-black turbidity, which was obviously a failure.

Liu Yu was not angry, he poured the discarded medicinal liquid directly into the drain pipe and discarded it, and then began the second refining of the purifying light.

……

The Purifying Light was extremely difficult to refine, and of the five raw materials, Liu Yu only succeeded once in the fourth refining, and the other times all ended in failure.

And the fourth, and only one that succeeded, he only got 30 milliliters of Purifying Light.

After the successful refining, the Purifying Light Elixir was divided into three test tubes by Liu Yu, and Liu Yu looked at the faint golden elixir in the three test tubes, and the corners of his mouth couldn't help but show a smile.

Don't look at the purification light in the refining process, it is all a blue-black potion, but the magic is that the moment the elixir is successfully refined, the original blue-black elixir will be instantly transformed into gold, and a faint golden light will be released when converted. It is precisely because of this wonder that this potion is named the Light of Purification.

However, the only pity was that with his current success rate in refining this potion, as well as the raw materials for refining the Purification Light existing in this medicine field, none of this was enough to support him refining the Purification Light in large quantities.

The Purifying Light Elixir, he can only put it on his body, as a hole card, and can only use it when he is cornered. The Purifying Light Elixir will also become his biggest killer weapon at this stage.

……

In the following days, in addition to injecting abilities into the essence of the elixir every day, Liu Yu cultivated abilities in his spare time, managed the medicine field, and occasionally instructed Ye Qing to cultivate.

Now Liu Yu understands that medicine is a foreign object after all, and if you want to become stronger, you have to pay attention to your own strength.

……

One morning, Ye Qing suddenly found Liu Yu with excitement on his face, only to see Ye Qing's excited face flushed, and the corners of his mouth were unable to hide a smile, he looked at Liu Yu and stammered a little: "Yu, Yu Shao, I, I, I have awakened the ability!" ”

Hearing this, Liu Yu was stunned for a moment, and then his face also showed joy, and asked, "Which system of abilities have you awakened?" ”

Ye Qing smiled so much that his mouth almost grinned behind his ears, and said, "There are two systems, which are the water system and the wood system. ”

Ye Qing actually awakened the two abilities, which made Liu Yu slightly stunned for a moment, but then he was also happy for Ye Qing. The more factions an ability awakens, the more comprehensive and powerful it becomes.

In addition, Liu Yu also thought that he had always been injecting abilities into the elixir of longevity before, and now, Ye Qing had also awakened the ability, and among the awakened abilities was the water system, which was the most suitable system for injecting abilities into the elixir of longevity.

At that moment, Liu Yu immediately gave Ye Qing a set of methods for training mental power and ability micro-control ability, he asked Ye Qing to hand over some of the affairs of the small building store to the four robot commanders to do, and Ye Qing had to spare at least six hours a day to train mental power and ability micro-control ability, so that he could reach the level where he could inject ability into the elixir of life as soon as possible.

Ye Qing also worked hard in this regard, Liu Yu gave him six hours of training every day, and he actually practiced for an extra two hours. In less than a month, he has already made some achievements in the control of abilities. And Liu Yu saw that Ye Qing was working so hard, and on this day, he also told Ye Qing about the way of injecting the elixir of longevity, and asked Ye Qing to participate in the refining of the elixir that day.

After all, Ye Qing was born with a hand, and he failed in the first few times he injected the ability, but with Liu Yu watching from the sidelines, there was no phenomenon of the potion explosion. It wasn't until the seventh time that Ye Qing succeeded once when he injected the elixir of longevity. After this time, Liu Yu officially handed over the matter of injecting the elixir of longevity into Ye Qing.

On the second day after Ye Qing's ability event ended, Mu Yue also suddenly found Liu Yu, only to see Mu Yue hand the small box she was holding in her hand to Liu Yu and said, "Brother Liu Yu, I have been studying the Lu Clan's Mechanism Technique for a while, and this small box is something I just made." ”

Liu Yu looked at the small box in his hand, his face was confused, but he just made a small Luban wooden box, why did Mu Yue still make a fuss and find him to show off.

But Mu Yue's next sentence directly shocked Liu Yu to the point of being scorched on the outside and tender on the inside.

I only heard Mu Yue say: "The manufacture of this small wooden box, I was also inspired by accident, don't look at this wooden box is not half the size of the palm, but the space inside this wooden box is enough for a cubic meter!" ”
