Anyway, their kind of masks can effectively isolate some harmful gases and substances.

After hearing Jiang Xiao's order, Jiang's bodyguards put on masks and gloves.

The more you go in, the darker the light is, but the smell is really good for them. But when Jiang Xiao saw Cui zhenchu, she knew that she should be more and more able to distinguish the bad smell from this kind of smell. Those two kinds of smell should be really not good things, so her eyebrows are more and more wrinkled.

Fortunately, they all wear masks.

"Mom, put on the mask, too." Jiang Xiao and they have already put on masks. Cui zhenchu has a mask specially made by Jiang Liushao for her, which is much better than ordinary masks in isolating odor.

But Cui zhenchu didn't wear it at this time.

"No, I'll wait. I'll have to smell it again, or it'll be hard to tell the difference."

Cui zhenchu this time in order to help Jiang Xiao and Cheng Cheng, is really completely out.

Now if she wore that special mask, how could she know if there were any different changes?

"But -"

JIANG Xiao is still a little worried.

Cui zhenchu comforted her and said, "it's OK. Don't forget that my sense of smell is absolutely sensitive. If I smell that kind of smell is poisonous and has an impact on me, I will put it on immediately."

Cui zhenchu took out the mask first and put it on, but pulled it to his chin.

When she finds something wrong, she can pull up the mask immediately, so there is no danger.

"Well, mom, be careful. If you really find something wrong, put on the mask." Jiang Xiao didn't force her to put on the mask. That's because she felt that the Lingquan water and medicinal materials in her space might be more effective than before. Even if Cui Zhen didn't react at the beginning, she could cure her immediately after she was poisoned.

So she's not particularly worried.

They keep going in.

Tick tick.

There are some drops of water dropping down bit by bit, shooting down in the stone nest on the ground, making a very pleasant and ethereal dripping sound. After a little echo in the cave, it sounds like endless silence and ethereal feeling.

At this time, Cui zhenchu felt the change of the smell.

The flavor of the fragrance is a little lighter than before, that is to say, the two bad smells have already covered the sweet smell.

Even Jiang Xiao can smell it.

"Why do you think the sweet taste is lighter now?"

The closer it is, the lighter it tastes?

Cheng Cheng sucked, nodded and said, "I also feel that the sweet taste is not as strong as before."

"It's not that it's not that it's not sweet, but that the other two smells have covered the sweet smell, but there is still a sweet smell."

Cui zhenchu looked around. When he got here, several directions diverged in front of him, and a fork appeared.

But with Cui zhenchu leading the way, they can't go wrong at all.

"This way."

Cui zhenchu distinguishes and takes them to one of the entrances.

If you go further, the terrain seems to be going down, and it becomes very difficult to walk. Later, there is no road.

In front of him appeared a cave full of twists and turns and all kinds of strange stones.
