With Du Lin's guidance, several people quickly packed the items they needed into their pockets, tied the safety rope around their waists, Du Lin took the lead, Luo Fu'an was second, He Wenwen was third, and Ge Wei was last, and they went into the thief hole in turn in a posture of head and foot.

Ge Wei also held a plastic pipe in his hand, and on the other end of the plastic pipe was a diesel-powered blower, which was used to ventilate the underground tomb.

The entrance of the thief cave is about one meter, and it is not difficult to go down at first, and even for a thin girl like He Wenwen, it is very easy to turn around inside.

But the cave gets narrower and narrower as it goes down, and when it comes to the bend at the bottom of the hole, it is already difficult for Doolin to continue to push inside.

It can be seen that the tomb robber who dug this hole must be very thin.

After turning a right-angled bend from the vertical robbery hole to the horizontal robbery hole, Durin crawled forward with difficulty for about five meters, and could no longer move forward.

Illuminated by the light of the searchlights overhead, a brick wall appeared in front of him. Durin felt that if he was not mistaken, there should be a tomb tunnel behind this brick wall.

Durin pushed hard with his hand, and found that with his strength, the wall did not move.

Du Lin knew that the walls of the tombs of the Ming and Qing dynasties were often made of arched bricks. That is, the cross-section of each tomb wall brick is slightly trapezoidal, and a special adhesive is mixed with rice washing water, glutinous rice flour and pigskin glue to build the tomb wall bricks together in an arched arrangement, so as to resist the pressure of the outside world on the tomb road or tomb to the greatest extent.

As for why the arch arrangement can resist external pressure, in the Chinese textbook, everyone should have heard the story of Zhaozhou Bridge, and if you don't understand, you can flip it, and I won't use the name of "popular science" here to count the words.

The sturdiness of this kind of wall is very strong, and it is very difficult to destroy the tomb wall with external force, and it is estimated that the tomb robbers who dug this hole are also because they can't take this wall, so they retreat back and think about another idea.

But this little difficulty naturally can't be hard to live our male protagonist, Du Lin looked back, and found that the people behind him couldn't see their movements, so he took out a bottle of old vinegar that was more than five years old from his shoulder bag, unscrewed the lid and poured it on the wall, waited for a few seconds, and used a knife to pick a few times in the brick joint, and found that the adhesive had softened a little, so he poured some old vinegar on it, and after repeating it several times, the brick joints on the four sides of one of the wall tiles were completely exposed.

The brick wall of this arch structure is mainly resistant to the pressure of the outside of the wall inward, and the resistance to pressure from the inside to the outside is extremely poor, so During picks at the wall tiles with his fingers and pulls them outward.

This is Durin, under his super strength, he soon felt the loosening of his fingers on the wall tiles, and he hurriedly asked the person behind him to put on the breathing mask he was carrying.

Because some family members of the deceased in order to prevent tomb robbers, after the body is buried, will sprinkle mercury into the tomb, that is, mercury, after the mercury evaporates, a large number of mercury molecules will be mixed in the air, if you accidentally inhale, you will immediately appear dizziness, headache, nausea, vomiting, diarrhea and other poisoning symptoms, if the concentration of mercury molecules is very large, you may faint on the spot, and even die.

Even if there is no mercury, the air that has not been circulated for more than 100 years will definitely not smell very good, and you still need to wear a breathing mask.

With the force of Durin's hands, a wall tile weighing nearly a kilogram was pulled out of the wall by him, and a stream of air rushed out of the tomb, and then the air outside poured into the inside of the tomb.

In this kind of wall, as long as one brick is cut off, the other bricks can be easily removed.

I saw that Du Lin took down the wall bricks one after another and passed them to the people behind him, so that they could carry these bricks out of the cave hand by hand, and these bricks would still be used when the tomb was repaired in the future.

In a few moments Durin dug a large hole through which he could pass through, and he looked into the graveyard and, seeing that there was no danger, jumped straight down from the hole.

"I haven't asked you to jump yet, why did you jump down?" Luo Fu'an, who was behind him, leaned out half of his body from the entrance of the cave and "seriously criticized" Du Lin.

Du Lin stood in the tomb and looked up at Luo Fu'an, his expression could not be seen through the breathing mask, but Luo Fu'an clearly heard the sentence "stupid 'B'.

Luo Fuan felt that his leadership authority had been challenged like never before, "What did you say?

"Talk about your sister," He Wenwen, who was behind Luo Fuan, had already adjusted her position and kicked Luo Fuan's buttocks, "Hurry up and give me down, give way to my aunt and grandmother!"

It may be because He Wenwen has drunk immortal blood, and her physique is much stronger than that of ordinary young women, and her strength in this foot is extremely strong, and she directly kicked Luo Fuan out of the hole.

Caught off guard, Luo Fuan only had time to let out an exclamation, and a dog fell on the graveyard below, and before he could get up, He Wenwen jumped down from it again, and "accidentally" stepped on Luo Fuan's hand, which hurt him so much that he "snorted", holding his palm and shouting in pain.

"It hurts me, you broke me!"

He Wenwen just wanted to teach him a lesson, first, to make Du Lin angry, and second, he did not like him, but if he really broke a bone for others, he still felt a little reluctant to go.

"Fifth brother, take a look at him, is he really fractured?"

Du Lin went over to see Luo Fuan's hand.

"Don't move, it hurts! It must be a fracture!" Whether his hand is broken or not, of course Luo Fuan knows best, he just wants to pretend that the fracture makes He Wenwen feel guilty, so that it is convenient to launch an emotional offensive against He Wenwen in the future, so he immediately twisted his body and dodged Du Lin's outstretched hand.

But Du Lin's hand was so easy to dodge, or Du Lin grabbed the "broken" arm, Luo Fuan tried to withdraw his arm, but the huge force from Du Lin's hand made him dare not move.

Luo Fuan felt that Du Lin grabbed his arm, which hurt more than when he was stepped on by He Wenwen, and if he screwed with him again, I am afraid that he would really break his bones.

Du Lin touched Luo Fuan's palm twice, and let go of his hand in disgust, "No fractures, okay, hurry up, now is your 'academic' affairs, Luo 'Captain'." ”

Du Lin said the word "captain" very clearly, and the irony was very obvious, but Luo Fuan didn't hear it.

"Do you still know that I am the captain? From now on, all actions are under my command, and no one is allowed to move the things in the tomb and the tomb, do you understand?" After finishing speaking, Luo Fuan glanced at the other three, Du Lin was observing the structure of the tomb and ignored him, He Wenwen was sorting out the wrinkles that did not exist on his clothes, and ignored him, only Ge Wei nodded.

Luo Fuan, who finally found a little confidence in Ge Wei, walked towards the tomb with his hands behind his back, but did not find that Ge Wei gave him a middle finger after he turned around......

Luo Fu'an walked a few steps and found that none of the three people had followed, so he turned around and beckoned, "What are you still doing in a daze?

The three of them all looked at him with idiot-like eyes, of course, there was a breathing mask in the way, and Luo Fuan couldn't see it.

"If you don't go, I'll go first, you hurry up and follow!" After speaking, Luo Fuan walked forward alone, and soon disappeared into the darkness, only to see his flashlight shining around.

Half a minute later, Luo Fuan walked back dejectedly.

"What's wrong, Captain Luo?" He Wenwen asked evilly.

"Maybe I was confused by the fall just now, I turned a little, that is the beginning of the cemetery, we should go this way. ”

Du Lin sneered, shook his head, and walked in front first, He Wenwen followed closely and walked side by side with Du Lin, Ge Wei forced a smile and asked,

"Brother Luo, let's go?"

"Let's go!" Luo Fu'an hated the roots of his teeth, but he was helpless, who let himself go in the wrong direction in a daze?

Ge Wei pulled the plastic pipe into the tomb and used the walkie-talkie to notify Miao Weijie, who was left behind, to turn on the blower, and soon, a strong air flow erupted from the pipe, and I believe that soon they will no longer have to wear breathing masks.
