Ouyang Ping turned over the photo, and there were several data behind it:

Thief Cave Deep, 7. 3 meters;

The entrance to the cave is about 70 centimeters long and 50 centimeters wide.

The thief hole is 7 deep. 3 meters, the rope ladder is about eight meters long, which is exactly the same. The first point of convergence between the two cases finally emerged. This means that the two cases are becoming more and more related.

Common sense tells us that the robbery hole should be round, and the rectangular robbery hole is the first time that the comrades have seen it.

Ouyang Ping took a photo and said, "Professor Gu, how can the entrance of the thief cave be rectangular?" ”

"This is the first time we have encountered this kind of robbery hole. Judging by the bronze tripod we found in Tomb No. 1, look at this photo-" Professor Gu picked out one of the stacks of photos and handed it to Ouyang Ping.

The photo shows a rectangular bronze tripod.

"There is data on the reverse side of the photo." Professor Koo said.

Ouyang Ping turned the photo over: the copper tripod is 66 cm long, 46 cm wide, and 68 cm high.

It is a four-legged bronze tripod.

Ouyang Ping finally understood what Professor Gu meant: "At the beginning, the hole dug by the tomb robbers was round, and after entering the tomb, they saw the bronze tripod, and in order to get the bronze tripod out of the tomb, they dug the robbery hole into a rectangle. ”

"Yes, it should be, and this is the most reasonable explanation. In all the burial chambers we excavated before the Han Dynasty, most of them have such large sacrificial vessels. Come, and I'll take you into the tomb. ”

"Is this convenient?"

"It's convenient, I'll take you to see the thief hole on the boxwood question, and you will completely understand."

Ouyang Ping and his entourage followed Professor Gu, walked out of the tent, walked through the narrow passage, and then slowly walked down more than 20 steps of earth steps—earthen steps are reserved for archaeologists to enter the pit.

Walking down the last staircase, there is a one-meter-wide door in front of you, which is the door of the entire burial chamber, and the east and west sides of the door are flat piles of strips of wood. The length of the strip is 0.9 meters, and the height and width of the cross-section of each strip are 10 centimeters, which means that the thickness of the wooden wall of the burial chamber is 0.9 meters, and there is a very long piece of wood pressed on the top of the wooden wall.

In the words of Professor Gu, the author's so-called strip wood is "boxwood", which is the cypress with a yellow heart, and Professor Gu's so-called "problem" is the end of the cypress near the root, "Minato: that is, the roots of the cypress are aggregated inward and stacked together."

After Professor Gu said this, everyone finally understood what the "boxwood question" was all about.

The arrival of the comrades did not attract the attention of other archaeologists, who still continued to do their own thing at their own pace.

An archaeologist about 50 years old walked out of a circular corridor and came to Professor Gu, holding a milky white ring-shaped jade pendant in his hand, the outer diameter of the ring-shaped jade pendant was about 10 centimeters, the inner diameter was about 6 centimeters, and the thickness of the jade pendant was about 1 centimeter. The body is carved with some very delicate but not very clear patterns.

"Professor Zhang, where did you find this?"

"In the northwest corner of the last coffin, there is a thin layer of charcoal on top of this jade pendant, and when we remove the charcoal, we find this jade pendant." Professor Zhang said.

"Let's go inside." Professor Koo said.
