After finishing speaking, Shen Yan carefully looked at the stout willow tree.

She found that the further she went to the root of the tree, the more salt crystallized.

Finally, a small hole caught Shen Yan's attention between the two exposed roots.

Although he didn't know what was in there, Shen Yan still put his hand inside.

After all, she is invincible, even if there is some kind of poison in the cave, it will not affect her.

Night Shura and Mu Jinchen on the side knew that they might not be able to help in this regard, so they could only look around vigilantly to protect Shen Yan's safety.

Carefully groping in the cave, after touching for a long time, Shen Yan felt a small metal ring in the deepest part of the cave, presumably this is the key to entering the place of Gu cultivation.

"Be careful, I'm going to turn on the mechanism."

After whispering a reminder to Mu Jinchen and Ye Shura, Shen Yan's fingers hooked the small ring, and without much effort, he pulled it away.

However, after waiting for a long time, nothing has changed around.

"Strange."

Muttering in a low voice, Shen Yan let go of his hand.

Just as the brass ring bounced back to its original position, the sound of click, click, click, click, sounded in the quiet environment.

I saw that on the road next to the weeping willow, three bluestone slabs slowly sank down and turned into a downward step.

At this moment, the blue jade bird suddenly flew from the branch, and in the blink of an eye, it flew into the deep darkness under the steps.

Gusts of wind also blew up from the unknown depths of darkness.

Shen Yan stood beside him, and suddenly, there was an idea that this place might be the entrance to hell.

Beneath the ground, there was danger she couldn't foresee.

But the closer you talk about danger, the closer you get to the truth.

This truth is really too hard-won.

After taking a few deep breaths, Shen Yan's clear eyes looked at the two men next to her, she knew that in this case, if she proposed to go down by herself, they would definitely not agree.

All she could do now was try to make sure that the two of them wouldn't get poisoned.

Thinking about it, he took out a small bottle from his pocket, poured out two pills from the small bottle, and gave one to the two of them, one for each of them.

After that, he took out two more small flowers and handed them to them.

"This pill is for Gu repellent, you have to eat it now, this little flower is so that you won't be confused by the toxin of the nightmare moth, remember, once you see something that can't appear in this world, put the little flower in your mouth and chew it......"

After explaining the things that should be paid attention to, and waiting for the two men to take all the medicine, the three of them entered the dark corridor in turn.

I thought that there was no light in this corridor.

The night Shura who walked in front took the fire fold out of his clothes.

But as soon as the three of them walked in, the walls on both sides of the corridor began to light up with green phosphorus fires one after another.

Under this strange light, everything in the corridor can be seen clearly.

It's white, whether it's the surrounding walls or the floor, it's all white.

After Shen Yan lightly touched the wall, he felt that this was simply incredible.

In the middle of the capital, there is such a salt cave.

The place where I first came down was an artificial entrance, but no matter how you look at it, it is a naturally formed salt mine cave.

In the land of the capital, in the Prime Minister's Mansion, there is such a huge salt cave, and it is impossible for the Prime Minister not to know about it.

Then, all this that happened in the capital is probably inseparable from the prime minister.

Slowly, the three of them walked very cautiously into the depths.

The air here is very dry, and the more you walk, the wider the road becomes, like a trumpet, and when you get to the end, it is a huge salt cave.

Chirp, tweet......

At this moment, the sound of the bird sounded, and following the sound, the blue jade bird landed on a huge piece of salt, and on top of the salt block, there was a white cloak.

"He should be nearby, let's be careful."

Mu Jinchen said in a deep voice, and the long sword in his hand had already been pulled out by him.

However, before a few of them could continue to explore in this salt cave, the sound of flowing water suddenly sounded.

In the middle of the salt cave, a spring suddenly appeared on the otherwise dry ground.

Immediately afterward, around the spring, columns of water emerged one after another.

In the blink of an eye, the huge ground has become a salt lake.

It was at this time that something began to tumble and swell in the salt lake.

Shen Yan looked at it, and a layer of cold sweat appeared on his body.

Gu snakes, densely packed, hundreds of Gu snakes, gushed out from the spring.

The appearance of these Gu snakes was exactly the same as the red snakes that appeared in the palace, the only difference was the color.

The inside of the palace is red, and at the moment, the inside of this salt lake is white.

It is written in the book about Gu making that Gu snakes are black when they are first cultivated, and as their toxicity increases, they will become dark red, dark red, and light red.

By the end it turns white until it is transparent and has no color.

And now the snake that appears is pure white, which shows that the poison of this Gu snake is already very strong.

"Don't be careful, you must not be ......"

Before Shen Yan finished speaking, a group of white Gu snakes had already attacked them.

However, the situation is not particularly bad.

After all, the two people with the best martial arts in the world today are standing by Shen Yan's side.

The sword light flashed, and those Gu snakes that arched their bodies and jumped in the direction of the three people were cut off by a volley before they could get close.

"It's too much, it's not the way to go on like this."

Night Shura was busy and shouted at Mu Jinchen.

Mu Jinchen naturally understands that dragging it like this is not a long-term solution, the space of this salt cave is too large, and the area of the salt lake is also very large.

They were already standing near the edge of the salt cave, and if the water rose again, they would have to retreat to their original path.

Therefore, for a while, Mu Jinchen couldn't think of any countermeasures.

Just when the situation was getting worse and worse, Shen Yan, who had been looking for other cave entrances next to him, shouted excitedly at the two of them.

"Here, come on."

Hearing this, Mu Jinchen and Ye Shura retreated to Shen Yan's side while repelling the attacking Gu snake.

Next to the large block of salt, which was almost submerged in water, and where the white cloak was placed, lay a chain wrapped in salt crystals.

After the two of them reached his side, Shen Yan pulled the chain up with all his might.

Boom.

The ground beneath their feet began to shake, and a round tray-like thing slowly rose upwards to support the three of them.
