Mu Kaifeng found someone to prepare some torches and brought them for everyone to use for lighting along the way.

In the past few years, Han'er has also read a lot of books about ancient tombs, and generally knows some necessary skills for going to ancient tombs. He asked Sui Han to throw down a few torches first, and tested the gas composition inside with an open flame to make sure that there would be no open flame explosion, and then he himself also held the torch and took the lead to walk inside.

"Han'er, wait a minute. Su Kexin called out behind him worriedly, and hurriedly followed closely behind, holding his wheelchair and helping him move forward.

Sui Han, the ghost woman, the rakshasa and the Hades king also followed into the cave, and a group of mermaids entered.

The cave is a little downward, and there are some inscriptions carved on the stone walls on both sides, but the characters are strange, with lines and circles, like paw prints, and I don't know what they mean.

Everyone turned their attention to Rakshasa and Hades, both of whom were demon beasts, but they were also confused in the face of these strange words.

Han'er didn't speak the whole time, just stared at the words on the wall, and sometimes frowned, thinking about something.

Su Kexin didn't bother him, Han'er was used to the silence of being alone, and only when it was quiet, would his brain spin rapidly.

Sui Han was also worried about the mother and son, and he walked in front, and the more he walked inside, the narrower the cave became, allowing only one person to barely walk through, and winding in, the light of the torch could not shine much in the place, and over time, people had an indescribable sense of oppression.

"There should still be living creatures here. Han'er suddenly stared at the wall and said.

Su Kexin was stunned, "How do you know?"

Han'er pointed to some marks on the wall and said, "The traces left by this demon beast still have some debris between its fingernails, you see. ”

Han'er gently picked at it with his hand, and the crumbs fell and landed on his palm.

"If it was something more than a hundred years ago, I am afraid it would have been petrified a long time ago. ”

Everyone was moved, everyone thought that Mu Kaifeng had exterminated all the remnant demon beasts at that time, but they didn't expect that at the bottom of his barracks, there were still demon beasts surviving.

It seems that they didn't do enough to cut the grass and eradicate the roots back then.

"Since there are still living demon beasts here, everyone be careful. ”

Sui Han instructed everyone and took the lead again.

Suddenly, everyone's eyes lit up.

There seemed to be something bright in front of him, which instantly relieved the darkness and pressure in the space, and everyone was overjoyed, could it be that there was an exit ahead?

But the truth is clearly not that simple.

When everyone finally turned around in the narrow path, what they faced was a man-made lake, and the sparkling water in the lake was actually mercury.

Su Kexin hurriedly said: "Everyone cover their mouths and noses, be careful of poisoning." ”

She took a few pills from the space, distributed them to everyone, and said, "Everyone take it under the tongue, don't inhale too much." ”

Everyone nodded one after another, and it was really a good thing to have an accompanying alchemist.

Sui Han walked over slowly, and gently touched the surface of the mercury with the end of the whip, and the point where the mercury touched the whip formed a small bulge.

"Strange, this mercury is very toxic, if there are demon beasts living here for a long time, won't they be infected by this poison?"

Hades said: "In the Demon Beast Realm, many demon beasts can adapt to all kinds of harsh environments, including places filled with poisonous gas. ”

On both sides of the mercury lake, there are two stone sculptures, one of which is more than one person tall, one is an eagle and the other is a tiger. It's just that the faces of the two demon beasts are skeletons, and they look very scary.

Rakshasa's hand gently brushed the eagle's head, as if he had realized, "Hey, why does this statue look so much like you?"

You, of course, are referring to Hades.

The Hades King has always been showing himself in human form with Mu Kaifeng, and his true appearance was only really seen by Su Kexin when he was in the registration office.

Hades also took a few steps forward and looked at the tiger-shaped sculpture, "This tiger is more like Arnold, could it be that we all know the person who carved this stone statue?"

Rakshasa's heart moved.

The two of them didn't know many people in the Biluo Continent, and they couldn't think of anyone who could have stone carving skills in their memory for a while.

If it is a carved hand, it will definitely leave its name or mark on the statue. Rakshasa wanted to explore, so he held the statue in his hand and searched around.

And just as her hand gently moved the eagle to the side, the stone seat of the statue was actually moved away by her.

"Ahh

An instinctive reaction made her exclaim, knowing that she might have triggered something by accident.

"Don't move. ”

The Hades King hurriedly supported him, the terrain they are in now is very dangerous, once something happens, all the people here will not be able to escape.

However, it seems to be too late.

At first, there was a dead silence all around, and it seemed that nothing had changed, but suddenly, a little ripple began to appear on the calm water.

Yes, it's small ripples. The waves are sparkling, like the surface of the water in the sun.

Unfortunately, it wasn't water, it was mercury.

To be able to ripple mercury is not an ordinary power, and besides, there is no wind blowing in this cold cave.

The rest of the story was a little bit unpleasant.

The ripples grew bigger and stronger, like a turbulent sea going back and forth, and a big wave would hit at any moment.

The edge of the mercury lake is not high, and once the waves are bigger than the border, the mercury will swallow up everyone here.

"Hurry back!"

The mercury suddenly set off a wave, and the huge waves slapped towards this side, everyone secretly screamed that it was not good, and the body jumped straight up, Sui Han was by Han'er's side at that time, and in a hurry, he instinctively held Han'er in his arms, and his body also rose into the air.

But this cave is only more than two meters high, even if you jump up, how much can you dodge, the mercury wave slapped over, the wave height still hit below everyone's knees, and a bone-deep pain immediately spread throughout the body.

Su Kexin said anxiously: "Han'er, are you okay?"

When she saw the cold and danger, she was still thinking about her son for the first time, and Su Kexin was quite moved.

"Mother, I'm fine. Han'er also let out a long breath and said that it was impossible not to be afraid.

But in an instant, the mercury retreated again, and the force of the retreat was greater, which meant that when the wave hit the second time, it would be higher and more violent than before.

And the entrance when everyone entered the cave just now has been tightly blocked by mercury at this time, and the back road has been cut off.

If mercury continues to rage like this, everyone can only wait for death.

Su Kexin was helpless, and she also fought, her eyes were ruthless! She let go of her hand holding the top wall of the stone wall, and her body fell straight down.

"Xin'er, danger!"
