In a blink of an eye, it has been three days since Liu Cheng's [Primary Herbal Medicine] upgraded.

During these three days, Liu Cheng was still busy with the task of "Conquer the Island".

However, Liu Cheng's luck was very bad in the past three days. Although he had reached 51% in the exploration of the island and was quite fast in the exploration, this was just the only thing that Liu Cheng had in these three days that he could make him feel more happy.

It’s not because of this that Liu Cheng has no other gains. This is really something, but it just makes Liu Cheng not very satisfied.

Early the morning after Liu Cheng's upgrade of [Primary Herbal Medicine], Liu Cheng's "Basic Boxing" also moved from [Introduction] to [Master]. This should have been a very popular thing, but Liu Cheng just couldn't be happy.

The reason is very simple, that is, the proficiency of "Basic Boxing" has improved, but Liu Cheng did not feel that he has become much stronger. Although his strength and spirit have indeed improved, the improvement is not very large.

However, although it is not big, it has been improved in the end. At least after the improvement of "Basic Boxing", Liu Cheng's four-dimensional attributes have finally been improved. The original 3-point force has been increased to 5 points, but Liu Cheng really couldn't see the difference between these 3 and 5.

In addition to the unsatisfactory improvement of "Basic Boxing", there is another thing that makes Liu Cheng very depressed, that is, the harvest of the treasure chest.

Originally, Liu Cheng thought he might have been lucky and dared not expect to have a [dashed treasure chest] in a day, but one in two days or three days should be found. But what he didn't expect was that his luck was much worse than he expected. Liu Cheng's [dashed treasure chest] in a [dashed treasure chest] in a whole three days.

It would be fine if this alone. Liu Cheng's luck seemed not limited to the treasure chest, but also affected the weather.

On the seventh day when Liu Cheng began to explore the island, Liu Cheng was driven back by a rain as soon as he went out.

Originally, this was nothing, it was just a rain, and Liu Cheng just needed to hide when he went home.

What Liu Cheng did not expect was that the rain was as long as he expected. It started on the seventh day of Liu Cheng's exploration of the island, and he had no intention of stopping.

Originally, Liu Cheng planned to complete the task of [Conquer the Island] within a few days. After God did this, Liu Cheng could only stay in that shelter honestly.

Fortunately, although Liu Cheng was exploring the island during the day, this guy was not idle at night. In addition to practicing "Basic Boxing", and collecting materials, Liu Cheng also spent a lot of energy on the shelter.

Not only has the shelter expanded a lot, but it has also been reinforced with wood so that Liu Cheng will not worry about being wet or the shelter will collapse due to heavy rain. In addition, Liu Cheng beats the snake while exploring the island these days, so he doesn't have to worry about food.

However, it was impossible for him to go out after a heavy rain. Although the shelter was much bigger, there was no room for him to stretch out to practice "Basic Boxing". When he was bored, Liu Cheng focused on [Primary Herbal Medicine].

After Liu Cheng's proficiency in [Primary Herbal Medicine] was improved to [Master], the system prompted him to try [Refining Medicine].

Liu Cheng was very interested in refining medicine.

However, the system only gave a tip for refining medicines in this regard. As for how to refine medicines, and what medicines to use to practice the system, there is no explanation at all.

Originally, Liu Cheng had no intention of thinking about these things, but now it was raining. Liu Cheng, who was idle, held a lot of herbs he had collected in the past six days and squatted at the door of the shelter to study.

I have to say that Liu Cheng, who was bored, was still willing to devote himself to this aspect. This guy held a lot of herbs and spent a long time to finally figure out something.

Liu Cheng's research on [Refining Medicine] started from the medicinal properties. He has reached the mastery of [Primary Herbal Medicine] and has a much more thorough understanding of the medicinal properties of herbs than before.

In addition, with the branch skill [herbal analysis], Liu Cheng soon developed something.

In order to verify his research, Liu Cheng went out to make a fist-sized stone and a few pieces of wood he used when he was strengthening the shelter.

After returning to the shelter, Liu Cheng used a fine iron dagger to dig the pieces into a bowl shape.

After spending a half day to get a set of basic tools, this guy got some food for himself and then he began to experiment with his guesses after he had enough energy.

As for how to verify my guess, of course it's a test. This guy plans to try whether he can refine medicine by himself.

I have to say that after just squatting on the ground and studying for a long time, he dared to refine medicine. Liu Cheng is definitely the first one. Fortunately, this guy took a wild path without a master's teaching, otherwise this guy would have to be beaten if he had an idea just now.

But this guy didn't do it casually, and he had some ideas about how he got it so quickly.

This guy used [herb analysis] to find several herbs with conflicting medicinal properties, and then put these herbs into the wooden bowls he made and mashed them with stones!

Because Liu Cheng did not have professional tools in his hands, this step alone took Liu Cheng an hour until his hands were swollen when he knocked, and he smashed the three herbs he chose.

After mashing these herbs, Liu Cheng put the three herbs into the bag that had previously loaded steamed buns, then placed the bag on a stone, and pressed a stone slab on the bag!

Waiting for the green juice to penetrate from the bag, Liu Cheng carefully put it in a wooden bowl, and completed this step. Liu Cheng's first refining medicine was over.

However, the refining of medicine is indeed over, but I don’t know whether it is successful or not.

Liu Cheng looked at the bowl of green juice in front of him and scratched his head slightly, not knowing whether he had succeeded in refining the medicine this time.

At this time, I have to admire the humanity of the system. Just as Liu Cheng scratched his head, a system prompt sounded at the right time.

[Ding, you have successfully practiced semi-finished medicine, you have learned special skills [Refining Medicine]!]

[Ding, you have successfully learned special skills [Refining Medicine] and obtained branch skills [Pill identification]!]

[Ding, you have successfully developed semi-finished medicine, and your skill [Refining Medicine] is improved by 1 point!]

Three system prompts rang out in a row. After carefully reading the system prompts, Liu Cheng had the illusion that he seemed to be awesome...
