The smiling faces of the army and Kuroko immediately became nervous again.

"Take the golden palace lamp and the jade statue, and hurry up!" Kuroko advised.

At this time, the army, which is particularly sensitive to smells, suddenly shrugged his nose, "What smell?"

When he said this, the four of them couldn't help but sniff it carefully.

"There seems to be a faint fragrance, which is emitted by this white plaster!" Sun Zhongyuan frowned.

"It's not good! it could be poisonous!" Dajun immediately opened his bag and took out a few simple gas masks, "This Cao Cao is too calculating!"

The four of them hurriedly put on their masks, and their faces were cold.

This white plaster was originally piled up in the place where there is a hole to block the hole, and where there is no hole, it is smeared on the mountain wall, and the outside is covered with green bricks, and there is no smell at first, but after digging up the green bricks and pulling out these two large piles from the mountain cracks, now, these two large piles of scattered white plaster have begun to exude this faint fragrance!

This should also be calculated by Cao Cao, in case someone discovers the natural passage, and the gas emitted by this plaster, you can't get out!

Probably toxic!

Fortunately, the speed of this thing should be relatively slow, and it only starts to work with a fragrance, and it needs a certain amount of accumulation. Fortunately, they found out early and immediately put on gas masks.

Moreover, after all, this time is too long, nearly two thousand years have passed, and I am afraid that the effect of this poisonous gas will also subside somewhat.

Another point is that no matter how meticulous this Cao Cao's calculations are, he should never have imagined that future generations would invent things like gas masks and gas masks.

Therefore, they are in danger.

Kuroko shouted, "No, this coffin can't be opened, in case there is any mechanism, we may not be able to prevent it!"

Chen Danyang thought for a while, "We hid in the stone crevice and used the rope to pull open the lid of the outer coffin, there should be no problem, right?"

The army and the sunspot agreed on the same opinion, and waved their hands again and again, "The human heart is not enough to swallow the elephant, stop it!"

Sun Zhongyuan groaned for a while and said to Chen Danyang, "In this way, let's go out first and see if we can go out, if we can go out, rest and recuperate, and then it's not too late to come back! This place really can't stay for a long time now!"

Chen Danyang hesitated, but agreed.

The four of them packed the package, took the "spoils", and went down to the stone crevices in turn.

At first, this stone crack could only allow one person to bow and pass through on his side, and a taller person like Sun Zhongyuan was a little more difficult than the three of them. And the few packages that were made were tied up with ropes and slowly dragged behind them.

The stone crack is more tortuous, twisting and turning, however, after five minutes of walking, a relatively large stone cave appeared, and the stone cave is connected to a passage more than one person high and nearly one meter wide.

In the cave, the four of them re-tied their backpacks, and one of them carried one on their backs. At the same time, the four of them still didn't feel any discomfort, so they took off their gas masks, which was really uncomfortable to wear.

Then they all ate something and drank some water.

Sun Zhongyuan took out a cigarette and sent one by one.

Chen Danyang took a sip hard, "It is said that Cao Cao is the ancestor of tomb robbers, and I am now convinced, the calculation is too powerful!"

"Then you still want to move his son's coffin?" the army spat out a puff of smoke rings, "If you move, the flying needles and arrows shoot indiscriminately, no matter how special they are, they will be quenched and poisoned, then the ball will be over!"

"That's why I said to hide in the cracks of the stones and pull them with ropes!" Chen Danyang replied.

"Let's see if we can get out first! This passage, if it leads to a long-distance closed underground river, it will be troublesome enough!" Sun Zhongyuan extinguished the cigarette, "Let's go!"

The four of them walked into this passage one after another. Fortunately, the flashlight emergency lights are all available, and the road is bright. Also, there are no strange animals or anything like that in this passage.

The passage turns a few corners, but the overall direction is all downward. They roughly estimated that after walking for a while, they should have reached the location of the underground.

Walking and resting, until eight o'clock in the morning, they came to a stone cave again, the top of this stone cave is uneven, the highest point is more than three meters high, the lowest point is only more than one meter, the mountain stone above is uneven, the foot is also quite uneven, the end of the stone cave, revealing a faint light, as if it is a very large angle downward inclined channel.

Chen Danyang was a little excited, and rushed to the end of the stone cave in three steps and two steps, wanting to take a look.

However, the stone at the end of the stone cave looked a little rough, but it was slippery, and as soon as Chen Danyang stood up, he stumbled and slid straight into the passage!

The three of them were several meters away from him, and they couldn't help but exclaim, it was too late!

Chen Danyang thought that his body would slide against the stone wall, but he couldn't touch anything, and fell directly in the air!

Thump!

He actually fell into the water!

Sun Zhongyuan came to the mouth of the passage and carefully supported the stone wall probes on both sides, only to find that below the mouth of the passage, there was no longer any stone wall, just like a wellhead, and below, there was an underground river with a width of more than five meters!

The surface of the river is about six or seven meters from the "wellhead", the water looks deep, flows slowly, and is not fast, and the surface of the river looks relatively calm.

Sun Zhongyuan breathed a sigh of relief and shouted at the location where Chen Danyang fell into the water:

"Are you alright?"

At the same time, Dajun and Heizi immediately took out the rope and prepared to hang Chen Danyang up first.

"It's okay!" Chen Danyang was okay with his water, and he raised his head in the water and controlled his body.

At this moment, there was a "sudden" motor sound on the water in front of him, Chen Danyang immediately turned his head to look, and actually found a small pleasure boat heading towards where he was!

There are two rows of seats on this cruise, and more than a dozen people are seated. There was a man in the boat, and a little girl with a horn, who happened to open her mouth at this time:

"Ladies and gentlemen, we are now in the middle of the underground Grand Canyon Lazy River, which is the deepest part of the underground. There are no caves and stalactites in this section, but there are upright stone walls on both sides, and there are a large number of natural holes at the top, and the scenery is unique······"

"There are people in the water!" A curly-haired aunt with sharp eyes found Chen Danyang.

The cruise ship immediately approached and stopped beside Chen Danyang.

"Gotcha!" Sun Zhongyuan retracted his head from above and looked at Dajun and Kuroko, "He was saved by the cruise ship below." ”

"We'll jump too!" Kuroko said.

"Pull it down, let's jump like this, won't scare these people stupidly? Since there is a pleasure boat that can come in, wait for him to go out, and find a way to meet us!"

Kuroko laughed, "Fortunately, he is the thinnest, so he didn't let him take the golden lamp and the jade elephant." ”

"But he also has a lot of tools on his back, can he get past the people on the ship?" the army couldn't help frowning.

Sun Zhongyuan had already found a stone to sit down at this time, and lit a cigarette, "He can." He has the certificate of the land and geology department on him, and he is bald and slugging at the police in Funiu Town, and when he comes back, it will definitely be fine. ”
