Su Bai was finally able to catch his breath after he had talked to the audience for half a day.
Unlike the front hall of Cao Cao's tomb, the back hall was slightly more cramped.
As the main tomb, the front hall was the place where Cao Cao slept after his death. It was almost completely built according to the Wei Palace in Xuchang before Cao Cao's death. The back hall was used to store funerary objects, soldiers, weapons, and so on. Naturally, the specifications could not be compared to the front hall.
"Master Bai, this is a treasure trove, right?”
"I wonder how many treasures Cao Cao buried inside.”
"Just thinking about the cultural relics from 2,000 years ago inside makes me feel anxious.”
"Master Bai, you must show us later.”
The audience followed the camera and looked at the rear hall. They were all excitedly spamming the bullet screen.
Compared to the danger of opening the coffin, treasure hunting was more interesting.
"Don't worry about that. I'll bring you in later to see how many rare treasures Cao Aman has hidden in the tomb.”
Su Bai nodded.
He also wanted to know which rare treasures Cao Aman, the founder of the Gold-looting Commandant, who had stolen countless ancient tombs from the Pre-Qin and Warring States Period, had brought into his own underground palace.
With his backpack slung over his shoulder, Su Bai held the flashlight in one hand and the Luoyang shovel in the other.
Right now, the only weapon he had with him was this Luoyang shovel.
The Swiss army knife was stained with the poison of the cockscomb snake. Su Bai didn't dare to take it. He threw it on the corridor outside the main tomb and fed it to the white-haired female corpse.
If there was another dumpling in the back hall, Su Bai could only accept his fate.
He carefully walked to the front of the back hall. Just like the main tomb, he entered the back hall through a stone door.
"Another stone door?"
"There won't be another Ghost Blows Out the Light this time, right?”
"I was wondering why the tomb builders didn't have any innovation. They could have made a wooden or bronze door.”
"It's a trap tomb? In my opinion, it's trash."
Su Bai didn't pay attention to the arguments on the bullet screen. He just carefully observed the stone door in front of him.
It was still the Hou pattern.
It was indeed Cao Cao's style!
Su Bai sighed. He pushed the stone door with his palm, but it didn't budge at all. It didn't have any intention of opening.
"The stone door is closed. Brothers, it seems that we will have to wait a while before we can see the treasures inside.”
Su Bai shook his head helplessly and said to the camera.
"Is it not easy to enter?"
"Lord Bai used Ghost Blows Out the Light.”
"It's not about the ghost blowing out the light. This stone door is an airtight door. Unless we open a passage in the wall and let air in to balance the pressure, the stone door will open with a push.”
Su Bai explained.
"What's an airtight door?"
" Before sealing the stone door, the tomb craftsmen burned the air in the underground palace, so the air pressure would naturally decrease. The air outside the underground palace would be maintained at a normal level, so there would be a difference in air pressure between the two. The high air pressure would squeeze the low air pressure, and the stone door would be like an air pressure valve. It would be impossible to push it open with brute force.”
Su Bai squatted on the ground, picked up a stone and gave a simple explanation to the audience.
"F * ck, we just passed calculus, and now it's physics.”
"Master Bai is really f * cking awesome."
"Master Bai, tell me, is there anything you don't understand?”
"Let me count. To become a qualified tomb thief, you must have the Book of Changes, Feng Shui, Xunlong Dianxue, astronomical phenomena, tomb studies, mathematics, physics, and yes, you must also have a good mentality and be strong enough to deal with monsters like dumplings at any time.”
"Oh my god, I'd better not go to the tomb.”
"I'm desperate, I'm completely desperate. It's not easy to be a tomb thief.”
"Master Bai, I really have to hand it to you. Just how many things did you learn before entering the tomb?”
After listening to Su Bai's analysis, everyone in the live stream was so shocked that they couldn't say anything.
Forget about the basic knowledge of the tomb, he had to be proficient in mathematics and physics. Was this still a tomb? Why was it completely different from the tomb thieves in novels?
Wasn't it possible to just pull anyone into the tomb?
"Didn't I say it? The tomb is a technical job. It's definitely not as simple as you think.”
Throwing away the stone, Su Bai dusted off his hands, got up and took out a knife from his backpack.
The starting knife was one of the must-have equipment for tomb thieves. The blade was extremely thin and could be inserted into extremely small gaps.
He chose a spot close to the stone door and gently inserted the blade into the gap between the green bricks.
"In ancient times, in order to prevent tomb thieves from entering the tomb and destroying the tomb chamber and stealing treasures, the construction of the wall was extremely particular.”
"There was no cement or concrete in ancient times. What was used to build the city walls and important facilities?”
Su Bai asked as he carefully removed the substance in the cracks of the brick wall.
"Yellow mud? My hometown used to mix yellow mud when building houses.”
"I think it should be clay."
"Clay? Isn't it? Clay was used to make pottery and paper burning porcelain, alright?”
"Then what did you use?"
"How would I know? Anyway, Master Bai definitely knows.”
Su Bai felt helpless when he saw the bullet comments. He put the black ashes under the camera." Look, this is the ancient cement used to build the ancient city wall. It was made by smashing boiled glutinous rice, mixing it with sand and stones, and making it called rammed earth.”
"Before cement and concrete were invented, the ancient city walls and important military facilities of China were built with rammed earth.”
"Glutinous Rice? Isn't that too extravagant?"
"Didn't they say that the grain production in ancient times was small? How much glutinous rice did they use to build so many cities?”
"Why do you care how much glutinous rice people use? Can you listen to the class properly?"
He kept removing the earth between the two bricks with his knife. Soon, two cracks that were big enough for Su Bai's fingers to penetrate appeared under the camera.
Su Bai put away his saber.
His right middle finger and thumb held the brick tightly.
He took a deep breath and exerted force.
Bang!
With a dull bang, a black brick weighing nearly ten pounds was torn off from the wall by Su Bai. Ignoring everyone's exclamation, Su Bai kept tearing off the bricks one after another until a half-meter-wide passage was formed.
After waiting for a few minutes, Su Bai estimated that the pressure in the underground palace had risen.
Only then did he walk to the stone door.
"Watch carefully. I'll let you see what it means to use four taels to deflect a thousand pounds!”
Su Bai smiled at the camera, pressed his palm on the stone door and pushed it lightly!
Creak ~
Under everyone's astonished eyes, the stone door that hadn't moved before was pushed open by Su Bai!
