Qiao Erzi and his sons took out the compass and calibrated the red line of the longitude and latitude of heaven and earth, so that the north and south pointers were pointing to the positive position, that is, the north and south directions. After adjusting the compass, Qiao Erzi and his son recited the mantra: "Heaven and earth are positioned, the mountains are ventilated, the thunder and wind fight, and water and fire do not shoot." The gossip is wrong, the number of the past is good, and the one who knows the future is reversed, so it is easy to reverse".

Qiao Erzi and his sons carefully rotated the compass while reciting the mantra. After that, the compass points to the right.

Qiao Er said loudly: The compass points to the right, open the door to the west, follow me!

After some consideration, Qiao Erzi finally found that there seemed to be a doorway at the right turn in front of him.

After Qiao Erzi and his son ran in with others, they found that there was a stone wall at the end of the doorway. It's about a foot high. As soon as the hammer saw the stone wall, he patted his chest and said to Qiao Erzi: I think this tomb of the king is only so capable, poke a wall here, and if I come alone, I can collapse it for him! Qiao Er, do you want to use my hammer to get out of the horse?

Iron Hammer has always been direct and reckless, and he will never use his brain to solve the things that he can solve with his strength. Probably based on the biological evolution principle of "use in and waste out", he is young, and his strength is increasing year by year, and the strength of this body is the capital he shows off, but his brain has not grown much like his body, it is still the same rough and simple.

At this time, Qiao Erzi hurriedly raised his hand to the hammer and interrupted him. Otherwise, he thought that Qiao Erzi and the two sons acquiesced, and they really spread their legs and punched or kicked at the stone wall, and now there are so many people, and they can't figure out the form, in case they accidentally touch any mechanism again, it is not impossible to confess them in this thousand-year-old tomb.

Qiao Erzi took a torch and shone it on the stone wall, and sure enough, he found that there was a groove about two inches deep in the extremely hidden place of the door frame of the stone wall, and there was an iron chain the thickness of his fingers buried in the groove. The chain was hung all the way to the top of the stone gate, and at the top of the stone door there was a groove that made the chain fit inside the groove, and then fell all the way to the back of the stone door. Qiao Erzi guessed: The reason why this stone gate is so designed must be based on the needs of the mechanism. If the maker of the stone gate relies on the weight of the stone gate itself to keep people out, then what is the function of the stone trough and iron chain? Moreover, the stone trough and the iron chain were kept so secret, it was obvious that the maker did it on purpose, and his purpose was not to let people find out, and he didn't want people to avoid the mechanism behind it. In that case, what kind of secrets are hidden behind the cumbersome stone door of this stone door?

Qiao Erzi hurriedly groped under the stone door, and after looking for a long time, Qiao Erzi finally felt a bulge the size of a corn kernel in a very hidden place in a corner under the threshold. Qiao Erzi and his sons rolled and crawled, and finally rolled out of the landing range one second before the heavy object landed. After the heavy object hit the ground, Qiao Erzi and his son found out that it was a big copper lump nearly four feet long that was nearly one person high. It seems that the ancients of the Shang Dynasty knew for a long time that the people who came here to rob the tomb would look for the mechanism, so they deliberately lured the king into the urn, let the tomb robbers activate the mechanism by themselves, and then kill themselves.

Qiao Erzi wondered in his heart: Didn't the ancients think that if they really met a quick master and could dodge the heavy blow of this big copper block, then what should they do?

Qiao Erzi was thinking about it, and suddenly felt a trembling tingling itch in his legs and feet. He felt the ground shaking. Suddenly, where he was standing, another stone gate rose, and Qiao and his sons did not dodge, but rode on the top of the stone gate, and followed the stone gate all the way up.

Iron Hammer and all the people underground were dumbfounded, Iron Hammer put his hands together in his mouth, and said upward: Qiao Er, you want to play "Lift High", what's the matter? Come down!

But Qiao Erzi and his son looked at the stone wall that was rising higher and higher, and couldn't help but be afraid. But he also understood: at this time, he had to jump, if he didn't jump down quickly, then after the top of this stone gate came to an end, he would be squeezed and crushed to death. Suddenly, there was a sharp metal collision sound above his head, Qiao Erzi and the two looked up, only to see dozens of sharp steel knives suddenly sticking out at the interface between the top of his head and the stone gate, all of them with the tips pointing downward, and extremely sharp.

Qiao Erzi and his two sons only found out at this time: it turned out that there were dense grooves on the stone gate he was riding. These grooves are the spaces that the builders have deliberately left for these sharp steel knives.

Now that the stone gate is rising little by little, Qiao Erzi and his sons are getting closer and closer to those steel knives. He originally thought that he would be squeezed and crushed to death, but now it seems that he is still too optimistic, because judging from the current situation, before he is squeezed to death, he will first be pierced into a bloody "hedgehog" by these countless steel knives.

Qiao Erzi and the two sons finally made up their minds to jump, or get out. Because jumping down requires standing up, but now there is definitely not enough space above his head, so he can only roll down.

Qiao Erzi was panting for breath, adjusting his mood, he thought about it! If he rolls down, the worst result will be to break his arm and leg, but after all, he can save his life, and sometimes, he has to abandon Zhu Baoshuai, break the wrist of a strong man, and have the courage and courage to stop the loss in time.

Suddenly, Qiao Erzi saw the soldiers of the tiger and leopard riding standing below, he had an idea, raised his hand above his head, touched and grabbed the top of the door, and shouted loudly: General Yu! I've got the key! Send a few men and get me down!

When Yu Bingzhong heard this, he immediately shook his head at the two soldiers riding tigers and leopards, and the two soldiers rushed to run, and climbed onto the stone gate with one foot, like walking on a flat road, and kicked to the top of the stone gate.

At this moment, the stone door slammed shut. Iron Hammer looked at the stone gate and said: Qiao Er, you said that this ancient man is true, we have already put a stone door and we haven't opened it yet, why did we put another one, isn't it in vain?

However, before the hammer could finish speaking, he saw black water suddenly spurt upwards from the ground, and the water carried a foul smell. At this time, the hammer suddenly realized that he seemed to scold: his grandmother's! I said, "How did he give this stone wall a door!" It turned out that he was going to spray dirty water on us, for fear of soiling the original place, so he first raised a stone door and blocked it! Qiao Er, you say that this person is so lacking in virtue!

Black water sprayed onto the stone gate, and hot white smoke suddenly rose from the stone gate.

Qiao Erzi and his sons found out when they saw it: It turned out that this stone gate was made of lime!

When lime sees water, it will become hot, and if you throw eggs into it, you can cook it. If the lime gate were soaked in water and suddenly collapsed, then they would all be buried alive with a large amount of lime.

Qiao Erzi shouted: Run back!

When everyone saw this, they hurriedly ran back the same way, but they were still one step slower, and the door of the road had been blocked.

At this moment, the water suddenly stopped firing, and the ground began to slowly flow mud. When the mud comes into contact with the lime, the ground starts to catch fire. It turned out that the liquid in the mud was not water, but oil.

Yu Bingzhong was so angry that he grabbed Qiao Er's neckline and shouted: What kind of heart do you have! Is it deliberately going to kill Ben here?

Seeing this, Iron Hammer hurriedly rushed up to push Yu Bingzhong, and said angrily: You don't know if your brain is not! Is it time for a fight? I'll tell you: if we don't find a way to get out, it's lime and flame, and we'll all end up being roasted people!

Yu Bingzhong threw Qiao Er to the ground and shouted angrily: "Give Ben General a way to find a life!" Fast!

Qiao Erzi fell to the ground, and suddenly saw: It turned out that at the bottom of the door frame where he touched the mechanism, there was an iron chain that kept turning.

Qiao Erzi hurriedly pressed the corn-grain-sized mechanism at the door frame again, but the mechanism had failed. At this time, Qiao Erzi picked up a hammer from the tool basket and smashed the door frame with all his might, revealing the mechanical principle. The principle of the iron chain drives a large stone like a water pump to send the transparent oil upwards. And an iron hook next to him was tightly hooking a ring carved from a boulder, Qiao Er pulled out a tiger and leopard knight's wrong gold and bronze sword, cut the iron chain and iron hook, the oil finally stopped flowing, and the stone gate also rose violently. All that was left in front of them was the original stone door.

Qiao Erzi kept touching at the stone gate, and finally touched a bead the size of an egg. He suddenly thought: Now in the customs of the original Song Kingdom of Puyang, when a man is hired, he must bring a woman a stone to support the door frame of the house, and in their concept, the water is in charge of the stone of the door of a house, and who is the head of the family.

Qiao Er thought to himself: Usually stones are oval-shaped, but why is this stone so round? Because the door stone is ground too round, the contact area will be reduced, and the contact area will be reduced, and the stability will be weakened. This thing is inevitably strange, but Qiao Erzi touched it again and found that this round stone holding the door could actually be rotated, Qiao Erzi and his son began to try to turn the stone, and found that it had no effect. But for some reason, he always had a faint premonition in his heart: this mechanism, this stone must have its use.

Qiao Erzi continued to turn the stone, and suddenly the stone was pulled out by him. Qiao Erzi took the round stone in his hand and looked at it, and couldn't help but be startled. It turned out that when his master Lin Guizang taught him skills, he also interspersed some miscellaneous knowledge. Master once said: "The Classic of Mountains and Seas" records a mineral called "water jade". Although the "water jade" is a stone, its color is extremely transparent, just like the spring water in the mountains, clear and flawless. Good water jade, its texture is extremely hard, no matter how much the knife splits the axe, it will not damage the slightest. And the light shines brightly, and under the illumination of the sun, it will emit a colorful glow. If a person wears this thing, his whole body will shine brightly, like a fairy in the dust. Therefore, it is a good tribute to the royal family by many barbarians. However, water jade has always been less favored than jade in the royal family, because the brilliance of water jade is too exposed, not as bright as jade, and it is subtle and introverted.

Seeing this, Qiao Erzi and his two sons realized: The transparent stone in his hand should be the water jade that the master said! To be able to use such a priceless water jade as a stone to support the door frame, such an extravagant act, I am afraid that only the king of Shang is the king.

After Qiao Erzi and the two sons pulled out the water jade beads, the door frame began to tilt and shake. As soon as Qiao Er and his son saw that the door frame was symmetrical, they hurriedly ran to the door frame on the other side and climbed down, and pulled out a water jade of the same size from the door frame on the other side.

As soon as the two water jades were pulled out, the stone gate collapsed.

What appeared in front of everyone was a stone room, but when Qiao Erzi looked inside, he couldn't help but feel his heartstrings tense, his scalp was numb, and even the hairs on his body stood up!
