Hearing Chunting's words, Chen Gong also smiled, and what we saw from his face was undisguised confidence.

"Don't worry, adults, fighting with people to kill Chen Gong may be a little inferior, but if you face such an organization, Chen Gong will naturally be fine."

As he spoke, he slowly walked towards the stone gate in front of us, ready to crack the mysterious tap stone for us.

Chen Gong has always been a doer, although he didn't talk much along the way, but since he is a descendant of Luban, he naturally takes it as a good person, and he looks at us with curious eyes, so he begins to seriously explain to us what the principle of this tap stone is.

The so-called tap stone, in fact, is just a hand-hewn stone, although the length is less than two meters, but there is a stone as a pass, as the name suggests, this is a stone that does not need external power, its main purpose is to block the door of the tomb.

When making this mechanism, the builder first rubbed the upper and lower ends of the stone door shaft into a ball, carved a groove with a protrusion on the surface of the stone door at the part that was in line with the door gap, and then chiseled out a shallow front and deep groove on the ground near the central axis of the door.

Before the burial chamber is closed, the craftsman puts the tap stone in the stone trough and puts one end of it against the tomb door, when the craftsmen withdraw from the tomb and prepare to close the tomb door, the tap stone will slowly fall by virtue of its own weight and the pressure of the stone balls at both ends of the door shaft, and automatically close the tomb door, hence the name.

As the stone slowly falls, until the top of the stone is connected to the notch left on the door of the tomb, the door of the tomb will be closed tightly, and the stone is magically automatically put on top of the door of the tomb, preventing people with ulterior motives from disturbing the peace of the tomb owner for thousands of years.

Since the mechanism is completed, the tap stone and the tomb door are countered, so the weight that the comer has to face is the sum of the weight of the 100-ton stone gate and the tap stone, under such a huge weight, if anyone wants to push the stone door open from the outside, it is simply wishful thinking.

When we heard Chen Gong explain the principle of this tap stone, we were worried while sighing, feeling the incomparable wisdom of the ancients, and worrying about how Chen Gong could open it under such difficulty?

But there was not a trace of anxiety on Chen Gong's face, and after he had explained the principle of the stone to us, he didn't say anything more, but kept looking around, and finally found what he needed under the city wall.

We looked in the direction of Chen Gong's gaze and found that they were two burial statues, different from the stone sculptures outside, these two statues were not stone sculptures but iron sculptures, a powerful armor, and an iron spear in their hands, as if they had been guarding the Vientiane Shrine for thousands of years under the city walls.

Chen Gong walked to the two statues, and with a force in his hand, he took the two iron spears from the statues' hands, and then tentatively bent them, the spears were actually a little tough, so he did not hesitate to bend the front of the spears into the shape of a cane, and then walked back to us.

Chen Gong asked all of us to push this stone gate together, although we were puzzled but we did not ask questions, but obeyed his command, with our efforts, although the stone door was not completely pushed open, but there was a small gap exposed, Chen Gong saw this gap and smiled slightly, as if this was the result he wanted.

Then, Chen Gong motioned for us not to stop, and he slowly stretched the spear with the curved front end through the gap, and after a few contacts, the curved part of the spear in Chen Gong's hand had touched the tap stone behind the door of the tomb.

Chen Gong relied on his senses, tried a few times, then put the spear back, seriously changed the arc of the spear head, and repeated this several times, until the arc of the spear was folded out just enough to catch the tap stone, he showed a satisfied smile.

After the arc of the spear can completely buckle the stone, Chen Gong motioned for us to let go of our hands, and then let us push the spear together, we were surprised to find that with our strength, the spear in our hands can lift the tap stone against the door little by little after holding the stone!

Chen Gong did not exert force with us, but waited for the opportunity, and after we tried to raise the tap stone to a certain height, Chen Gong quickly put another spear into the gap as well.

The second spear was pressed directly by Chen Gong against the tap stone that we were holding up, and then he ordered us to release the first spear, and then aimed at the second spear and pushed it out vigorously.

Rumble!

With a loud bang, the dust of the palace gate that no one visited for thousands of years was everywhere, and we waved our hands to disperse the dust that had been silent for thousands of years, and when the dust cleared, we were pleasantly surprised to find that the stone gate weighing 100 tons with a mechanism was pushed open by Chen Gong in a subtle way!

Niu Kelian had a guess from the beginning of Chen Gong's work, until we opened the stone door, he looked at Chen Gong and sighed sincerely.

"This Brother Chen must be a member of the current Guanshan Ministry of Industry, and his skills are really perfect, and I really admire him."

Chen Gong smiled honestly at Niu Ke, his face that was not good at words was a pride that could not be concealed, and his speech became smooth.

"Brother Niu praised it falsely, the construction of the organ is the duty of the Ministry of Industry, naturally I can't talk about admiration, but Brother Niu is secretly guarding the Vientiane Divine Palace here for the mission of your lineage, and people like you are truly worthy of admiration."

We didn't say anything when the two of us were sympathetic to each other, but after the stone door was opened, the scene in front of us was so spectacular that we were in a trance for a while, and we couldn't tell when and where it was.

According to records, in the vertical arch for three years, Wu Zetian ordered to demolish the original Qianyuan Palace, began to build the Ming Hall at the old site of the Qianyuan Palace, the hall is 294 feet high, 300 feet wide, a total of three layers are round covers, there are nine dragons around the top of the iron phoenix, one zhang high is decorated with gold, Wu Zetian in order to show the will of heaven, so it is also called the Vientiane Shrine.

This is the record of the Vientiane Shrine in the ancient books, after learning that this is the Vientiane Shrine, I thought this was just a simple palace, until this tap stone was cracked by Chen Gong, and the scene in front of me after the stone door was opened made me have to admit that we are still too naïve.

It is true that we can already see the towering Vientiane Shrine in front of us, but it is not just one palace, and what we see is a complete complex of buildings!

Before our eyes is a real city, a city buried deep underground that never sees the light of day!

Although I have never really seen the architecture of the Tang Dynasty, but I also have a general understanding of the architectural style at that time, in the spring pavilion when I first saw the spring pavilion, although it seems to be remote and quiet and antique, but compared with the book recorded there are some subtle differences, as long as you observe more after all, you can feel that it is a later generation imitation building.

But the city in front of us didn't feel that way at all, and standing by the stone gate and looking at the city, I think everyone would feel the same way as me.
