After three rounds of wine, five flavors, there is no banquet that will not be dispersed. The group swayed, insisted and went down the mountain again, leaving a few members of the archaeological team, Feng Weiguo and a few local personnel in the tunnel.

Professor Chen and Zhang Gong smiled at each other and fell asleep.

When the sound of birds woke everyone up from their sleep, Professor Chen saw that Feng Weiguo had already gotten up, squatted on the ground and carefully looked at the arrows that had been removed. Professor Chen walked over and greeted, "Curator Feng, it's good morning, I've been studying these arrows so early. ”

Feng Weiguo was too focused just now, he didn't pay attention to Professor Chen's movements, he was startled by the sudden voice, looked back at Professor Chen behind him, quickly stood up, and said to Professor Chen with an arrow: "Professor Chen, this arrow is 87 mm long, made of bamboo, boiled and repeatedly soaked and dried. ”

"In ancient times, including modern times, there is a process of boiling bamboo, the purpose is to change the structure, so that the bamboo will be stronger, in order to prevent insects, it will also be smeared with vinegar or camphor."

"Can you tell the age from this alone?"

"You can't jump to conclusions about this, you can only roughly define it after the crossbow is excavated."

"What is the history of the arrow carrying the toxin?"

"This was earlier, even before it was recorded. Most of the folk sources are extracted from plants or animals, and at that time, the official was basically an extension of the folk, and it was also divided into two categories, one is generally said to use dirty arrows to traumatize the human body, forming tetanus at the wound mouth, and the other is special-purpose, such as assassination and organs, and will not use ordinary gold juice and other ancient biological weapons, and will use extreme poison to smear the arrows, such as arsenic, blood to seal the throat, etc. ”

"Well, in terms of medical care at that time, infection was the biggest threat, and those dirty arrows became the earliest biological weapons."

"This arrow has been smoked with fire, and it has remained dark and shiny for so many years, and it must have been smeared with some kind of toxin."

"Broken intestine grass, crane top red, etc., should have been high-grade poisons at that time, right?"

"The statement that Hedinghong is poison has always been wrong, the so-called Hedinghong should be arsenic, the head of the red-crowned crane is non-toxic, and the whole body is a tonic.

"Oh, the first time I heard about it, it was an eye-opener again! I really followed you for a long time, in just a few dozen hours, my mind has broadened a lot, and it is not an exaggeration to borrow the idiom to describe it as a thousand miles a day, haha. ”

While waiting for breakfast, Professor Chen said to Director Feng: "It's not convenient to eat like this, it's better to let them get the pot stove to the tunnel opposite, and it's only a few dozen meters away from the bridge." ”

"It's good, but I'm afraid it's inconvenient, right? Hydropower or something. ”

"They must have water and electricity for construction, so with the assistance of Zhijun, let's fire on it, so it will cost a lot less work."

"Okay, I'll do it later."

After a while, the buns and soy milk were delivered, and after eating a steaming breakfast, the personnel were basically all in place, and Zhang Gong, with the help of Lao Ma, the ground-penetrating radar was also moved to the tomb.

The next day's work began in the sun.

Qin Gong, Ma Kai and local comrades surrounded the ancient tomb and began to explore the hidden caves, while Zhang Gong and a few others took Feng Weiguo to the front of the Hades Temple.

Except for the people from the TV station, the others were led by Professor Chen, and several people cautiously tried to move forward with their feet, and when they reached the small bridge leading to the middle, Professor Chen stopped and looked at the bridge made of white marble in front of him. The length of the bridge is almost 1.8 meters, the guardrail is nearly 90 centimeters high, and the bridge body is a monolithic, and there are no other patterns or carvings on the entire bridge body except for the chiseled steps. There are exquisite carvings on the guardrails on both sides of the bridge, the content of the reliefs is the scene of the life of ancient men, there are 6 reliefs on each side of the guardrail, each relief is a man of different shapes, or looking up, or walking, or practicing martial arts. Professor Chen looked at it and said to Zhu Gong, "Old Zhu, what do you think about this?" ”

Zhu Gong carefully looked at a few reliefs and replied: "I don't have the idea, through these 12 reliefs, I think it may be the life of the tomb owner, I don't know the content of the guardrail carving of several other bridges, if you look at it, you will not leave ten, but look at the characteristics of the bridge body and the characters in the relief, a bit of the Han Dynasty feeling." ”

"If it's the life of the tomb owner, then this tomb owner should be a warrior?"

"I guess so."

"This will be examined later, first go to the case of the central government, and see what this platform is for."

After speaking, Professor Chen looked at the dry river and continued to move forward cautiously.

Walking to the central case, Professor Chen realized that the case was made of stone, and the shape was relatively simple, with the endgame of chess placed on the case. The chessboard is made of white marble, the passage on it is finely carved and not colored, the chess pieces are made of black stone, and the chessboard is engraved with the four words "Chu River Han Boundary" in Lishu, and the chess pieces are also Lishu. Professor Chen looked at it and said to everyone: "The origin of chess is the pre-Qin period, and the characters on this chessboard are Han Li, which can also confirm our previous judgment, this is a tomb in the Eastern Han Dynasty." ”

Zhu Gong looked at it and nodded: "I agree with this point of view, this is the font of the heyday of the Eastern Han Dynasty, which has gradually got rid of the form of the Qin seal, and in the Three Kingdoms period, the calligraphy font has evolved." ”

"Then since it has been preliminarily determined that this is from the Han Dynasty, let's continue to verify it! Now the question is, is this chess endgame intentional? ”

Zhu Gong looked at the chess game seriously and said: "Now looking at the chess game is black chess, that is, the opposite chess is trapped, it should be that he pays too much attention to attack in front of him, and ignores his own defense, now the chess surface is black chess three pawns have been one pawn has been to the end, the other two are outflanking, the single horse in the middle to do the response, the single elephant single soldier and Shuai do the defense, and the white chess seems to be in the passive defense, but full of killing opportunities, Shuai sits in the middle, the cannon is at the bottom, the two soldiers are also on both sides of the soldier, obviously the black soldier is not guaranteed, the soldier is four or six flat five eat the soldier, the cannon five flat 5 eat the elephant, It's too late for the black chess horse to defend itself, and the victory or defeat is decided. ”

Professor Chen seemed to understand something, and hurriedly stopped Zhu Gong's words: "Wait a minute, Zhu Gong, do you mean that the black chess is lost?" ”

"That's how I see it, black will lose."

"I understand, if this chess is really lost, then there is no meaning to continue to put this, directly draw it or engrave it here can also express the heart, and now you can move around here, which means that this is not dead; This chess game may be the tomb owner's heart disease, and the endgame should also be a hint, not even a hint, to tell us that he was once troubled by this, but if the black chess moves first, can he have time to return to defense or come back to life? ”

"White moves first, and black loses!" But black should have the possibility of playing or winning the game first! ”

"In this case, don't care about anything else, you guys who play chess well study together, how can black win, and remember every move."

"Okay, let's shoot it first and then try it, this should be a big discovery."

Later, after taking pictures, they were ready to start cracking the endgame, but when they picked up a chess piece, they realized that the chess piece was made of magnets, and they felt obvious attraction when they took it.

Zhu Gong picked up the chess pieces and looked at them, then handed them to Professor Chen and said, "Old Chen, this chess game is not simple, it may be some kind of mechanism." ”

Professor Chen looked at the chess pieces, then squatted down to take a closer look at the chessboard and the case, and then gently knocked the stone case from the bottom with his hand, and finally understood the mystery: the chessboard was empty, and it was connected to the ground through one side of the case.
