Although these herbs placed in the groove of the stone platform are tasteless, they are so toxic that they are so stunning that Yang Kai is shocked.

But if you want to leave this ghost place, you can only fulfill the requirements described in small words on the stone platform. Yang Kai gritted his teeth and tasted those herbs he didn't know again.

It took him half a day to taste all the medicinal materials that he didn't recognize and could not be sure of whether it was toxic or not.

All kinds of pain and torture are simply indescribable to outsiders. If Yang Kai had not been strong in physique and strong recovery ability, he would have lost most of his life even if he was not poisoned to death.

This is true for him, and he couldn't get the fifteenth.

"Why are there thirteen kinds?" Yang Kai stood in front of the stone platform, his eyebrows condensed into a ball, and his face was incomprehensible.

Since the owner of this cave has left such a problem for the person entering, he will definitely not deliberately play tricks on others. In other words, there are indeed fifteen of these twenty-five medicinal herbs that are poisonous.

But Yang Kaiwang, Wenyin and Spicy have used all three methods, and he can only determine that thirteen are toxic and the remaining two cannot be found anyway.

How could this happen? His eyes swept through the grooves of the stone platform one by one, and no matter what, he could no longer find the remaining two.

Just when Yang Kai was at a loss against Shitai, all the warriors entering the cave were facing the same problem.

The warriors in the Fire Hall basically practiced fire-type skills, so the first stone chamber could not defeat them at all. They poured fire-type power into the stone platform like Yang Kai, and were teleported to the second stone chamber.

Even Consran easily passed the test of the first stone chamber.

And now, everyone is stumped by the problem of the second stone chamber.

In a stone room, a disciple of the Fire Hall looked at the twenty-five kinds of medicinal herbs and scratched his ears and heads.

He is not an alchemist, and he doesn't even know what these herbs are, let alone how to distinguish between poisonous or not. After waiting and watching for a long time, he selected several surely toxic medicinal materials from them. But the rest can no longer be distinguished.

As time passed, the disciple of the Fire Palace gritted his teeth and took out a medicinal material from the groove.

And the moment he took out the medicinal herb, the entire stone chamber suddenly buzzed. The stone platform in front of him sank at an extremely fast speed and disappeared in the blink of an eye.

The warrior was shocked and hurriedly floated backwards, moving his strength in case of accidents.

A buzzing sound came out. A little light suddenly flashed in the stone chamber. The light was densely packed and covered all over the world. When you count it roughly, there were hundreds of them. At first glance, it looked like the eyes of beasts, making people shudder.

The next moment, these flashing lights trembled slightly and bombarded the warrior together. The terrifying and terrifying energy fluctuations came out leisurely.

Seeing this, the warrior from the Fire Hall immediately showed a look of despair on his face. He had no time to roar and was flooded by the countless lights.

After a while, when the light dissipated, the disciple of the Fire Palace had disappeared from the spot. There was only a pool of red blood and broken cloth on the ground that proved that this person had existed before.

Not only this disciple of the Fire Hall encountered bad luck, but those warriors who chose the wrong medicinal materials all touched the ban in the stone chamber and were killed on the spot in one breath. The corpse was left untold.

In another stone chamber, Consran took out a herb from the groove of the stone platform in front of him with a serious expression. After waiting for a while, he found that he was safe and sound. He couldn't help but breathe a long sigh.

Although he is not an alchemist, he is the shopkeeper of Lingdanfang and a native star warrior. In terms of his knowledge and experience of herbs, Yang Kai is much more than today. After all, he is a person who deals with medicinal materials all day long.

So although the test in the second stone room was a bit difficult for him, it was not without hope.

There is also a stone chamber. Lian Yuming, the deputy director of the Fire Hall, looked at the twenty-five medicinal materials on the stone platform in front of him. He quickly selected more than ten of them in one go. Then he pondered and selected several of them, and collected thirteen. Moreover, the medicinal materials he chose were exactly the same as the types of medicinal materials that Yang Kai had worked hard to determine.

There are only two types left.

Lian Yuming's eyes were like lightning, and he was traveling through the remaining medicinal materials, searching for the knowledge he had mastered in herbs in his mind. After a stick of incense, he suddenly smiled slightly and took out the remaining two medicinal materials from the groove calmly.

And when he took out the last two medicinal materials, a light suddenly lit up on the ground where he stood beneath his feet, and a teleportation array appeared leisurely, teleporting him elsewhere. The stone platform in the stone chamber slowly sank at the same time.

...

In the stone chamber, Yang Kai still looked worried. During this period of time, he carefully identified the remaining medicinal materials again, but he could not determine which two types were poisonous.

Just as he was at a loss, he suddenly seemed to remember something and his eyes lit up.

Immediately, he quickly took out part of the remaining herbs, then combined them in pairs, rubbed them carefully and grinded them.

After a while, when he combined two of the medicinal herbs together and rubbed them, a pungent and spicy smell suddenly spread out from his fingertips. This breath made people dizzy and felt a burning sensation at his fingertips.

Yang Kai's mysterious skills dispelled the discomfort in his heart, and he looked happy and laughed, "You are right."

In this world, some medicinal materials are non-toxic themselves, but if they are mixed with some special medicinal materials, they may become highly toxic. This common sense is not only applicable to the alchemy world, but also common in the lives of some ordinary people who have not practiced.

Yang Kai did not think of this at first, but now this situation proves that his idea is correct.

He took the two reactive medicinal materials out of the groove with a confident look on his face and placed them aside.

The next moment, a teleportation array appeared under his feet. After the light flashed, Yang Kai's eyes turned black and the feeling of teleportation came again.

After he stabilized himself again, he turned his head and looked around, and suddenly he looked like he was not surprised, nodding and said, "It's true!"

The place where he was still a stone chamber, which was no different from the stone chambers he had visited before. There was also a stone platform in the middle.

At this point, Yang Kai had a vague guess at the role of this place. And judging from various clues before, it was probably the cave of the alchemy master Gongsun Mu.

He suppressed the joy in his heart, stepped forward and came to the stone platform.

Looking at me, I found that there were three identical medicinal materials on the stone platform. Judging from the aura emitted by the medicinal materials, the quality should not be high, and it is about the level of returning to the virtual level.

With his hand stretched out his hand to brush away the dust on the stone platform, Yang Kai looked at the boy on the stone platform and immediately understood the test content of this stone room.

It is actually necessary to condense the medicine liquid.

As long as the purity reaches a certain level, the teleportation array in the stone chamber can be activated.

Condensing the medicinal liquid is nothing to Yang Kai. He has done the work of condensing the medicinal liquid thousands of times so far since he refining the elixir. Moreover, he also has a special power such as the fire of spiritual consciousness, which can more easily condense the medicinal liquid and remove various impurities in the medicinal liquid.

And it is not very difficult to condense a medicinal material that returns to the level of deficiency.

As soon as he thought of this, he no longer hesitated and activated his own spiritual fire to wrap one of the medicinal materials.

After a moment, the medicinal material turned into a drop of green liquid, and impurities kept flying out of it, making the green liquid more clear and attractive.

Because she had already guessed about the various tests here, Yang Kai spared no effort when condensing the medicine liquid and performed perfectly.

When he condensed all the three medicinal materials into medicinal liquid and put them in the groove of the stone platform, the familiar teleportation array appeared again.

...

In the next few days, Yang Kai spent the next few days in a stone chamber. The tests given in each stone chamber were different. Some tests were used to draw spiritual arrays when refining alchemy, some needed to refine spiritual pills, and some tests were sure of the test... There were many different tests.

But all the content cannot be separated from the word alchemy.

By this time, Yang Kai could have completely confirmed his previous guess.

This is definitely a test of the later generations' mastery of alchemy. He is a master of alchemy, so it is not surprising that he can test the content in this regard.

As a generation of alchemy masters, he naturally hopes that his relics can be obtained by those who are also alchemists, rather than being taken away by some irrelevant people. After many previous tests, it is entirely possible to determine whether a person is a qualified alchemist.

Perhaps, Gongsun Mu might even want to find a successor for himself.

...

In the stone chamber, Yang Kai put a newly refined spiritual pill into the groove of the stone platform. After a while, a familiar teleportation feeling came, and the light flashed, and he disappeared again.

After Yang Kai regained his vision and looked around for a while, he couldn't help but look happy.

Because the place I am now is finally not the kind of unchanging stone chamber, but in a corridor.

The corridor was extremely dry, and there was a faint light of fire and strange grunts in front of it. The scorching aura filled the surroundings, making people feel like they fell into the magma in vain.

Yang Kai activated his power to protect himself and walked step by step towards the place where the fire light came from.

After a moment, he entered a cave.

I don’t know how many feet underground this cave exists, and there are no traces of artificiality, and it seems to be formed naturally.

In front of that, a red flame shone. Yang Kai narrowed his eyes and found that the flame was actually a flowing magma! The magma gathered into a pool, and from time to time, one or two bubbles emerged from below, bursting and sputtering.
