In the next passage, there was still poisonous gas. The vision in front of him was instantly blocked a little, and according to previous experience, it was necessary to take a short break before the poisonous gas would disperse somewhat.

"Ahem. Chen Tian coughed slightly. It's not that it's because of the poisonous gas, it's that the dust here doesn't make his nose very comfortable.

This is the underground palace, and the air is much worse than the outside. It's not a requirement, after all, being able to breathe and have enough oxygen to breathe here is already a lucky thing for Chen Tian to breathe.

The poisonous gas began to slowly decrease, and Chen Tian's cough subsided, and she began to look for clues in the poisonous gas.

The first step is to observe. Chen Tian found that the color here was slightly different from the previous one, Chen Tian didn't understand why the Medicine Saint only liked to set up poison gas mechanisms, and estimated that this was the simplest and easiest to kill people invisibly.

After all, any mechanism needs to be made. For the Medicine Saint, making poison gas is the easiest. Those trap masters might be more fond of swords and the like, or the secret passages and the like.

"I'd like to see how much poison gas is next. "Anyway, I've already taken medicine, my eyes won't be uncomfortable, and my body won't either.

Chen Tian swaggered down.

After walking through some stone ladders, I came to the bottom. There was still poisonous gas in this underground palace, but at this time, Chen Tian was no longer afraid of it.

Even, some of them are taken for granted. Chen Tian had a faint feeling in his heart, as if the cheats booklet must also have something to do with these poisonous gases. As long as you follow the poisonous place, it will definitely be safer.

Otherwise, the Medicine Saint would have no reason to waste his poison.

The most important thing must be used where it is most needed.

"Poison gas, why did it disappear?" Chen Tian was thinking about seeing what mechanism was in the poison gas land, but the poison gas was gone. Chen Tian frowned, and he began to worry that the clue was broken.

If the clue is broken, it will take more time to find, which will be more troublesome.

When there are clues, it is a shortcut to follow the vine and touch the melon. But now the shortcut has been cut off. Thinking of this, Chen Tian didn't come anywhere.

"I should have come down earlier!" Chen Tian was thirsty and hungry at the moment, and his mood was really not very good. An unprecedented sense of stress and anxiety came to mind.

Chen Tian was very worried that if he continued, his physical strength would be overdrawn.

Along the way, he didn't dare to eat the things on the road, although he occasionally saw all kinds of good-looking fruit trees, but the fruits on it that exuded a sweet smell, Chen Tian really didn't dare to reach out to take them.

It's not that I'm afraid of poisoning, I'm just afraid of vomiting and diarrhea.

In that case, it will be very troublesome for yourself. Master's explanation of his task is more important than anything else. But now he has little dry food left, and there is no water. If he continued, Chen Tian felt like he was going to fall here.

"You have to figure out how to get things done as soon as possible. Chen Tian said secretly in his heart.

There's no way, you have to speed up yourself at this time, if you continue, you may not have time.

"I knew I would have eaten some roast snake meat. Chen Tian thought of the giant snake from before, and those huge scorpions and the like from before.

Of course, these are just Chen Tian's jokes, those things, the body doesn't know what has been fed by the Medicine Sage, if you eat it yourself, you don't know what will happen.

Those poisons are very poisonous.

If it is neutralized with some cultivation in his body, so that his physique that is invulnerable to all poisons is destroyed, for Chen Tian, it will be too much to lose.

"I still have to find the mechanism!" Chen Tianxia subconsciously began to explore.

Underfoot, everything is normal.

Overhead, it looks like there's something special there.

Chen Tian's eyes came to the surroundings, and his hand began to grope on the stone wall little by little, and suddenly opened a mechanism, and then there was a very beautiful mural inside.

"Here, it's absolutely amazing!"

Chen Tian found that the murals here are really amazing. Absolutely beautiful, absolutely wonderful. The Dunhuang Flying Immortals above were vivid, and when Chen Tian's hand landed on the sleeves of those Flying Immortals, a voice suddenly sounded.

It turns out that the mural is also greasy.

Later, Chen Tian followed the guidance on the mural on the side and discovered the poisonous gas.

"It's poison gas again. "Chen Tian is used to seeing it. However, when he saw the poisonous gas for the first time before, Chen Tian was frightened, and now when he saw the poisonous gas, Chen Tian was surprised.

That's right, it's a surprise.

Because it means that there is nothing wrong with one's own path.

Chen Tian thought in his heart, the thing leading the way in the entire underground palace might be this poisonous gas. He secretly guessed: "Could it be that the previous generation of Medicine Saints knew that their descendants could be invulnerable, and they pardoned this organ, so that their descendants could find the secret book according to the poisonous gas?"

Although this speculation seems a bit nonsensical, it seems to be a bit reasonable.

After all, since he is studying medicine, being able to avoid all poisons may be the basic condition for the medicine saint to be able to learn his own booklet. That's why so much poison gas was set up.

The poisonous gas in each place is a little strange in color, perhaps because of the increasingly strong medicinal properties. Because later, Chen Tian felt a strange sense of oppression in the air he was in.

Generally speaking, it is the change in air pressure that makes the body feel this way.

However, the surrounding ones that can change the air pressure should be those poisonous gases in Chen Tian's opinion. So in fact, when setting up these poison gas mechanisms, the Medicine Saint is not the same.

It's a lot of differences. These are the clues. Chen Tian naturally would not let go of such an opportunity to understand.

It's just that for Chen Tian, all poisons do not invade, so it gives people the illusion that everything is the same poisonous gas.

If you are a layman who just comes to get the booklet and thinks about using it to buy money, it is estimated that you will basically die as soon as you enter, and it is very difficult to come here.

No wonder, apart from the gas trap, there are basically none.

"The Medicine Saint is a strange person!" Chen Tian muttered to himself. I admired the medicine saint very much in my heart.

At this time, Chen Tian suddenly realized, and almost instantly understood the reason for everything. At this time, his heart settled down a little.

He had the illusion that he was a destined person, the chosen one who had come here to find the things of the medicine saint. He followed the poison gas in one direction, and sure enough, after walking for half an hour, he found a trap box.
