On the deserted island, in Liu Cheng's shelter.

After spending more than three hours, Liu Cheng successfully brought back a certain number of herbs that were effective in treating wind and cold, and of course he also brought back a bunch of mud.

After all, after the heavy rain, even if Liu Cheng is barely a novice in the jungle, he will inevitably bump into and fall a few times when going out in this weather. Fortunately, the herbs were collected successfully.

However, although it is not easy to collect herbs, this is actually just the simplest part of Liu Cheng's mission.

The next step is the most difficult step and the biggest test for Liu Cheng. If Liu Cheng cannot refine these herbs into effective medicines, then no matter how many herbs Liu Cheng brings back, it will be useless.

Liu Cheng, who deeply understood this, didn't even remember to clean up the mud.

After returning to the shelter, checking the man's condition and confirming that the guy was fine, Liu Cheng simply ate something and focused on refining medicine.

Regarding the refining of medicine, Liu Cheng first had to do not deal with herbs or burn firewood, but to think about a recipe first.

After all, refining medicine is a meticulous job. Liu Cheng could not throw away everything and just make a fire and get it done. In that case, the possibility of failure is almost 100%.

In terms of formula, Liu Cheng was thinking about it when collecting herbs and had already had some initial ideas.

After returning to the shelter, Liu Cheng repeatedly pondered it and made sure that his thoughts were fine, the guy started to refine it.

While filling a basin of water with a porcelain basin, he put on a fire and boiled it, he simply treated the herbs that needed to be used. He tried to mash as much as possible and removed all the parts that should be removed. After everything was prepared, Liu Chengcai officially started his refining medicine.

Since Liu Cheng refined it, it was just a common medicine for wind and cold, and this medicine was at most an entry-level medicine, and the time it took for this medicine was not very long.

Light the fire and put the herbs in according to a certain order. In about half an hour, Liu Cheng's first basin came out. After finishing it, Liu Chengke threw it over with a [elixir identification].

[Ding, you succeeded in using the skill [Pill Identification]!]

While this system prompt appeared, Liu Cheng saw several rows of information when he looked at the pot of medicine soup.

Name of the elixir:???

Pharmaceutical grade: semi-finished product

Pill description: This is a semi-finished potion refined by a half-barrel of water. It has certain effects on treating wind and cold, but please take it with caution, because this is very likely to aggravate the condition of the taker and make the taker go directly to the west.

When he saw this information, Liu Cheng's face turned dark. It was obvious that his refining ended in failure.

Fortunately, Liu Cheng was mentally prepared early in the morning, and his failure failed to hit Liu Cheng.

After summarizing the reasons for the failure, re-deducing the elixir recipe he designed, and after repeatedly confirming that there was no problem, Liu Cheng took out the medicine soup from the porcelain basin and poured it out. After washing the porcelain basin, he came back to start a new round of refining.

After about half an hour, Liu Cheng's refining was completed again. However, this time, Liu Cheng's brows had already frowned before he could use [Pill Identification]. It was obvious that he no longer had any hope for whether his refining this time would be successful.

Then, Liu Cheng's [Pill Identification] was dumped, and the attributes of the semi-finished product came out, and the result proved his conjecture.

This time, Liu Cheng didn't hesitate much. After Liu Cheng, who knew he was wrong, cleaned up and then started his third attempt.

This time, Liu Cheng's face became more confident.

From the previous two refining medicines, Liu Cheng believed that he had found the best pill recipe, and this time he would definitely be able to refine this potion.

With this kind of confidence, Liu Cheng was highly focused and focused all his attention on this pot of medicine soup in front of him.

Under Liu Cheng's careful care, he quickly helped him pass again for half an hour. After confirming that his medicine soup was completed, the guy couldn't wait to throw the [elixir identification] on it.

However, when the elixir was identified, Liu Cheng was stunned because this time he ended in failure again!

Liu Cheng never expected that it was just a potion to treat wind and cold, and it was so difficult.

He had obviously used the optimal method based on the properties of the medicine, and it should have been successful, but he didn't expect it to end in failure, which made him unable to understand.

"What exactly is the problem? The one-sided formula I designed should be without problems! Judging from the properties of those herbs, why did this optimized elixir recipe fail?"

Liu Cheng was puzzled at this time, but because he was short of time, he could only think while starting his fourth attempt, intending to think and observe in practice.

However, because of the first three times, especially the third time, he was full of confidence and finally failed, Liu Cheng was a little distracted at this time and accidentally took an extra herb when placing the herbs.

When Liu Cheng realized it, it was too late that the medicine had already melted in. It was obvious that this situation was not necessary to see. This pot of medicine soup was probably ruined again.

For ordinary people, they might be pouring out the medicine soup at this time, but Liu Cheng is different.

Liu Cheng is very stubborn. He is not the kind of person who gives up easily. Even if he accidentally puts in more medicinal herbs, he has no idea of ​​giving up this pot of medicine.

He began to think constantly about how to remedy it!

Originally, Liu Cheng wanted to remedy this pot of medicinal materials as much as possible, but when he began to think about how to remedy it with one more medicine, Liu Cheng found that he seemed to have unintentionally opened up new ideas.

Originally, his unilateral prescription was designed with the optimal drug properties, but he did not take into account the issue of primary and secondary. In his original pill prescription, almost all the medicines were the main ones, and the problem arises here.

Although Liu Cheng was an otaku before traveling through time, he watched various TV novels and animations. Although he did not have an in-depth understanding of the potion, he had also heard of some fragmented information.

Among them, Liu Chengju knew that there was a difference between the primary and secondary monarch and minister in a pair of Chinese medicine, but Liu Cheng's pair did not. Perhaps it was because of this reason that he could not even configure a simple medicine to treat wind and cold.

After understanding this, Liu Cheng's eyes suddenly lit up.

He began to modify his original design pill recipe and began to constantly add other things to the pot of medicine soup. At the same time, he was constantly thinking about the medicinal properties of various herbs that he had calculated.

At this time, he felt a sudden enlightenment, as if he had realized the truth of some medicine.

However, under his trouble, half an hour later, Liu Cheng's [Pill Identification] still gave Liu Cheng a judgment on the failure of refining medicine.

But this time, Liu Cheng had no idea about the failure judgment because he was confident that he would successfully train the finished product on the fifth time.
Chapter completed!
