What Lin Shumin was holding in his hand was a jade plaque about ten centimeters square in length and width.

Shen Chuan had learned a little fur from Ye Tiancheng before, and even judged that the material of this jade plate was Hetian jade.

Moisturizing body and full of color.

Although the price is not high, it is often used as a large carving because of its soft texture.

Therefore, it is very likely that the jade plaque is engraved with the prescription he wants.

However, in the dirty. If the filthy thing is soaked for too long, it needs to be carefully handled to see the lines and symbols on the jade plaque.

Shen Chuan took out a sealed bag from his bag, and after taking the jade plate handed by Lin Shumin, he carefully put the jade card inside.

Then, he put it in his pocket.

"Next, you salvage everything inside, make sure there is nothing left, and then help someone cover the coffin!"

Although there is no body, no matter how you say it, you should respect each other by covering the coffin.

But at this moment, Lin Shuyao frowned.

"Do you smell anything?"

As soon as Lin Shuyao reminded him, Shen Chuan also vaguely felt that there was a smell like rotten eggs nearby.

Moreover, the smell came out when the coffin was opened.

Could it be said?

"Hurry up and put your helmet on......"

Shen Chuan roared angrily.

Although everyone didn't understand the situation, they hurriedly followed Shen Chuan's order and put on their helmets.

In this atmosphere, everyone is frightened.

A little nervous situation will implicate the hearts of several people.

Shen Chuan looked at everyone carefully, making sure that everyone's protective gear was put on.

Then, slowly walked towards the coffin.

"Because we cut off contact with Zhang Wei and them, we haven't paid attention to the ingredients in the air, and the smell of rotten eggs is probably biogas, or some kind of flammable gas. And the flavor is getting stronger! Bring me a flare! ”

With the previous lesson, Shen Chuan didn't dare to make a big deal about anything now.

The smell of rotten eggs is getting stronger, which means that the concentration of flammable gases is getting stronger and stronger.

Once this gas fills the entire space, or rather, the proportions reach a certain proportion, there is a high probability of an explosion.

Their protective suits can withstand the impact, but not the impact of such an explosion.

Moreover, the impact of the explosion may also be associated with landslides.

When the time comes, they will all have to be buried alive here.

After receiving the flare, Shen Chuan pulled the fuse and threw it towards the coffin.

With a bang, the flames rose more than ten meters high.

At the same time, the underground gas erupted.

It's like a whistling pillar of fire, like a large windproof lighter.

At the same time, the color of the flame also confirmed Shen Chuan's conjecture.

Dark blue.

It is almost certain that it is biogas.

Looking at this flame, Shen Chuan was silent for a moment.

If there is a space under the coffin filled with a lot of gas, does it mean that it is very likely to be able to get out of the space below?

However, we still have to wait until the flames burn out.

Otherwise, it is estimated that it will take less than a minute to go down, and it will be fully cooked.

After about five minutes, the pillar of fire began to slowly decrease.

Feeling that the gas below was about to burn out, Shen Chuan shouted: "Heavy baggage, after the fire is extinguished for a while, you take the hydraulic tongs, lift the coffin, and then see if you can open a tunnel!" ”

With Shen Chuan's order, several baggage soldiers took their equipment and walked to the coffin.

When the flames were extinguished, they worked together.

Soon, the coffin, which had been burned beyond recognition, was opened.

Then, it was a rush of work to face the ground.

Under the coffin, there are indeed several cracks.

However, it is not as easy to start construction on this thick mountain as it is to tear down the cave wall just now.

After more than half an hour, it was only dug down to less than one meter.

Shen Chuan gradually became anxious.

On Zhou Long's side, there was already a fever.

Moreover, Xiaoyun also seems to have suffered internal injuries, and her state is getting more and more depressed.

If you can't find your way out in an hour or two, everyone will probably have to give an account here.

"Mr. Shen, why don't we go back the way we came?"

"No, the monster must still be down there, in the water, we have no room to resist. And with such a large space, in the water, can you still find the way in? ”

The entrance to the tunnel is only three meters wide.

In this space of thousands of square meters, there is still deep water, and there is almost no light, and it is not difficult to find a three-meter-wide hole.

The reason why Shen Chuan was able to see the cracks on the waterfall before was entirely because there were a large number of luminous stones around the waterfall, and some light sources could be faintly seen.

But the hole in which they came down did not have a luminous stone.

Now that I'm going back the way I came, it's estimated that few people will be able to get out.

Shen Chuan only hoped that God would be able to favor him for so much at this time.

Either Lin Changsheng found a way out, or the space opened by the baggage soldiers could allow them to get out successfully.

"Mr. Shen, open ......"

Hearing the voice, Shen Chuan hurriedly ran over.

At the feet of the baggage soldiers, a crack as thick as a sewer had opened.

Look down through the light of a flashlight.

The space below here is much smaller than the hourglass-shaped space.

Moreover, at the bottom of it, there is a layer of sticky like crude oil. Thick liquids.

Biogas should be sticky from below. volatilized in thick liquids.

With a long exhalation, Shen Chuan turned his face to look at Lin Changsheng.

At this time, Lin Changsheng also surrounded him.

It seems that he did not find the passage.

Since this is the case, Shen Chuan is no longer procrastinating.

Tell a few people softly: "Come and two people go down with me first, and the others will wait here for the time being." Our helmet communication is still normal, and when you hear my order, you guys will come down! ”

As he spoke, Shen Chuan took out the baggage soldier and tied it to his waist.

Let him take the lead, and be the first to go down.

The space down there is much smaller.

The bottom of the cave is less than five meters high from the hole pierced above.

Soon, Shen Chuan landed to the point.

However, this bottom is jet black sticky. Thick liquids are very deep.

As soon as he stepped down, his knees were directly submerged in the pitch-black liquid.

Fortunately, it's not like silt that generally attracts people's feet.

It's a bit of a struggle to walk, but it's not too much of a hindrance!

Shen Chuan picked up the flashlight and glanced at it, feeling that this place was more like a passage than a hidden space.

Underneath the coffin, exactly at the end of the passage.

And when he took the flashlight into the distance of the passage, there was only darkness.

Zhou Long's two subordinates also went down to the passage at this time.

Although the atmosphere was depressing and terrifying, the two of them still guarded both sides of Shen Chuan tightly.

Xiao Yun and the others were not there, and the heavy responsibility of protecting Shen Chuan fell on their heads.

After observing the environment, Shen Chuan asked softly, "Can you hear it?" If I can hear it, I'll keep looking for the exit and say a word every five minutes! ”
