The cave had been detoured by us to the side of the fire-assisted room. It can be clearly seen that the top of the fire-assisted room was spliced ​​with long strips of stones. Because the place was too small and there were not many people, the job of prying stones was handed over to the four robots. The rest of us were guarding outside, while Gu Wenmin and others were preparing lunch.

After finding the opportunity, Tofu and I pulled Professor Lin aside. As soon as we talked about the situation, Professor Lin's expression changed and said, "I saw that note from the beginning and end. There was no record of any treatment for viruses. How could this happen? It's not good." He walked around in a hurry, and the person was dizzy. I said, "Uncle Lin, don't walk around. We came to you to think of an idea, not to let you hurry with me."

Professor Lin glared at me and said, "Can you not be anxious?" Four of the twelve people in the team may have been infected with the virus remaining in the 731st Unit. Isn't this serious enough?"

After thinking for a while, Professor Lin could only shake his head and sighed, "I really have no choice but to do it now. But today's medical research is not as good as before. Perhaps there is a solution to it. It seems that our actions must be accelerated, try to return to the inland as early as possible, and find a hospital to check it out."

Tofu looked at me and said, "I hope I was still a human at that time and didn't turn into a snake. Lao Chen, I want to turn into a snake. Will you throw me alone on the island?"

I said lightly: "For the happiness of the female snake on the island, I will definitely take you away." Tofu didn't hear it at first, but later after it came back, it immediately jumped three feet high. When I planned to settle the score with me, I had already put all my thoughts in the fire room under my feet. Now, what Professor Lin said is our only way out. It seems that we must seize the time and can't delay it anymore.

In a moment, I heard the sound of robot No. 1 coming from below the entrance of the cave: "It's clear, damn it, it's really smelly." After a moment, the four of them climbed up along the horse's hooves. They said that a stone had been pried open below, revealing a rectangular entrance that could allow us to enter. However, from below, there was a strong tar smell, and I felt dizzy when I smelled it. Although we had gas masks, the filtering effect of gas masks was limited, so we still had to wait for it to vent.

Not long after the two of them came up, the tar smell they described spread out along the hole. The outside space was relatively large, so they didn't feel dizzy, but the smell was really bad. Gu Wenmin said: "If there is really a fire that has not been extinguished for thousands of years, then there must be ventilation holes. Otherwise, there will be no air in the fire room, so how can the fire burn?"

I smelled the dull tar smell and said, "It was supposed to have stomata, but those stomata were probably blocked or destroyed for more than two thousand years. Therefore, the gas burning in the fire chamber has been stagnant. Now, only when the stones are pried open will it have such a big smell."

Duan Fei turned his eyes and asked with a smile: "Brother Chen, you said yesterday that you would use firepower to help the mountain. Now there is no fire. Wouldn't Xu Fu's back mountain collapse? Will it have any impact?"

I shook my head. I had never encountered such a thing before, and I didn't want to make random inferences. Everyone immediately packed up their equipment, ate and drank, and waited until the strong tar air below had almost dissipated, and then they prepared to go to the fire room. Since there were outsiders on the island, in order to prevent any accidents, we left carp, Aying and the others let go, and the rest of them put in holes one by one, and went into the pried rectangular entrance.

Our equipment was indeed sufficient this time. Everyone was wearing gas masks and gloves on their hands. There was no exposed skin on their bodies. The four robots were wearing bulletproof vests. Even if there were any hidden crossbows in the tomb chamber, they would not be injured. Ordinary people who dug mushrooms could not get the bulletproof vests. However, my grandfather told me before that the older generation of tomb robbers had many special tools used to dig mushrooms. As time went by, many of these tools had been lost, leaving only some sporadic clues.

For example, the bulletproof vest was used to have this thing, but it was not worn on the body, or rather it was called the "life-receiving umbrella".

What is a life-receiving umbrella? It is a big umbrella. After it is opened, no matter what mechanism secret crossbow is around it, it will be collected by the umbrella. It is amazing. It is said that because a large magnet is installed in the center of the umbrella, it can suck the secret crossbow with an iron head after it is opened. Of course, this is just a speculation by later generations that it is unknown how that thing was made.

I turned on the flashlight and shone down the rectangular hole, but I saw a dark area below, which was not deep. The place where I could see was a huge stone stairs downward, like an Egyptian pyramid that was not high, only about two meters away. Everyone jumped down one by one and finally entered the interior of this stone building more than two thousand years ago.

Tofu shines the flashlight down and says, "I don't know how deep it is, and I don't see the fire."

I said, "The fire should be at the bottom, but it has probably been extinguished now. This place was originally used to create momentum and form a pattern of guarding the three mountains, so at the bottom, there must be a passage that extends to the three peaks, one of which will directly lead to Xu Fu's underground palace. What we are looking for is not fire, but the tunnel."

In order to save time, I didn't say much, and went down while talking. The stone platform here is half a meter high, and people have to lean their bodies when they step down the stone steps. This underground building, which has been silent for more than two thousand years, has the unique simplicity and atmosphere of the Qin Dynasty. The rough stone steps cannot see any patterns, but they are layered and spread downward, giving people a sense of endlessness. In it, we are like a few little ants.

While I was going down, I estimated the depth, about twenty meters before we went down to the bottom. The inverted pyramid is square at the bottom, with nothing else. In the center, there is a huge tripod, three meters high, black all over, three feet and two ears, and a cloud dragon. The dragon is different from the current five-clawed golden dragon. It has no horns, no beards, no claws and no scales, and is an early dragon shape.

We cannot see clearly what the cauldron cover looks like above the cauldron, but this cauldron is obviously used to raise fire, and the cap must be hollowed out so that the internal medium fire can be burned.

Professor Lin only glanced at it and said, "It's indeed the style of Qin Shi, but there's something wrong..." Wu Sidong is professional after all. In addition to being jealous, he also has two brushes and said, "It's not easy to build such a large cauldron. You must know that this is the Japanese territory, which was still an uncivilized place more than two thousand years ago."

Gu Wenmin speculated: "If Xu Fu really brought his people to settle in Japan, he would definitely start a mine, and it would be impossible to cast such a large cauldron."

Professor Lin nodded and said, "What Officer Gu said makes sense." While he said, he told Wu Sidong and Duan Fei to take out their cameras to take pictures of the part of the tripod. This is the style of the archaeological team. Even if you cannot take things out, you have to keep photos or rubbings to study. While these people were taking photos, the rest of us scattered to find the "fireway" leading to the Sanshan Mausoleum.

This fire channel was not covered, but stood on the south side. A stone door was closed and it was not moved when pushed. It was obvious that there was a stone stone on it. However, this stone door was different from what we saw elsewhere. The stone door was not really sealed. There were many holes on both sides. Through the holes, you could see the situation behind the stone door. There was a straight forward passage behind it.

Tofu felt strange and inserted his finger into the holes of all sizes of the stone gate to grop, saying, "Why do you want to open so many holes?" Suddenly, he stared at one of the holes, his eyes not blinking, as if he had discovered something.

I couldn't help but move my eyes to it, but I saw the hole, which was about three fingers wide in diameter. Except for the difference in size and around, there was nothing special. So I asked what Tofu had discovered. He looked at the hole, then at his crotch, revealing a 'cease-solving' expression and said, "So that's it."

I didn't react for a while, and I was stunned for a while before I understood what the kid was thinking. I almost got angry. I kicked him away from the door and said, "Let you usually watch more serious things, and you don't listen. I just hold Japanese discs all day long, and now my mind is full of dirty thoughts. These holes are the crystallization of the wisdom of the ancient people. They have far-reaching significance and all-encompassing things. What the hell are you thinking about?"

Tofu covered his butt with a grievance and said, "A few holes are of far-reaching significance and all-encompassing. Just pull it. Don't you just want to kick me? You have to find such a high-sounding excuse. I'll tell you that rabbits will bite people if they are anxious, and brothers will turn their backs on their goals. If you can't say a word or two today, I will definitely avenge this kick."

I said, "Okay, since you want to listen, I will tell you. Look at the holes in this door, what is their arrangement?"

Tofu looked suspicious, but he turned his head and observed carefully. After a moment, his eyes lit up and said, "The upper and lower, left and right, are equal to ten. The smaller the number, the larger the hole, the five in the middle, and one and nine at the top... Hey, I seem to have seen it somewhere." Tofu buried his head and thought for a moment, then slapped his forehead and said, "I remember, it's your grandfather's work laptop. What's the name? Hetu or Luoshu?"

When I was working on research with my grandfather’s notebook on weekdays, I would occasionally follow him tofu, but he was impatient and would not see anyone after a few glances.
