I vaguely feel that although Guo Jia’s plan is perfect, we have less important factors to consider.

But it was too late to further improve this plan because the unmanned vehicle had already parked in front of a door. The unmanned vehicle emitted a melodious synthetic voice of artificial intelligence: "Two sirs, I have sent something important."

"Come in." The door opened.

Before the unmanned car entered, Guo Jia and Taishici, and I jumped out of the car and hid outside the door.

This is Guo Jia’s idea. After all, we don’t know how powerful the “body guard” inside the door is, so it’s better to observe it outside the door first.

Li Ru's voice sounded: "Beautiful work, I finally got this thing."

Li Su's voice sounded: "What is this?"

Li Ru replied: "This is an important item left behind after the explosion of Xingmei Mine many years ago. It can be said that it is a priceless treasure."

"It's really so amazing? Why don't you open the box and let me see it?"

"I'm just thinking. Zhang Liao, take off this safe first."

"yes!"

There was a sound of unpacking the box inside, and then Li Su's amazement came out: "It's such a thing. How did you get it back?"

"This is not my credit, it is Lord Dong Zhongying's credit." Li Ru said lightly: "And, for it, it has paid a huge price. Do you still remember the accident of the mine explosion many years ago?"

"I remember, it is said that a unique star marrow was found in that mine. Although it is highly toxic, it contains huge energy. At that time, the star marrow researcher of Chang'an Research Institute was sent to study this star marrow, but unfortunately a landslide occurred. Everyone except a little girl died..."

I looked at Guo Jia's face and her face turned pale. Obviously, what Li Su mentioned was about her and her family.

Li Ru said: "Brother Su, do you know the true face of that mine?"

Li Su said: "I don't know. If Brother Ru knows, you might as well tell me."

"Okay, this mine is actually a legend. It takes a long time to go back to a long time ago, when the Chang'an Parliament had not been established, and the King of Chu and King of Han were still competing for the battle..."

"The era when the King of Chu and King of Han competed?! That's quite old!" Li Ru said in surprise: "I'm afraid it will take hundreds of years to go back?"

"That's right. Listen to me. By the way, when the mine was just beginning to explore, I didn't find anything special. I happened to work in the mine exploration team and served as the deputy captain of the investigation team. That year we discovered Xingzhi in the mine, and everyone was very happy. However, after receiving the Xingzhi ore samples from us, the Chang'an Council and Chang'an Research Institute ordered us to block the news and sent special forces to ambush around the mine."

"England? Do you mean to prevent foreign enemies from invading that mine?"

Li Ru smiled bitterly: "I thought it was like this at first, but later I found out that I was not afraid of foreign enemies invading the mine, but that things in the mine ran out and invaded the world..."

"I can't understand what you said."

"It doesn't matter if you don't understand, I'll explain it to you slowly." Next, Li Ru began a long story.

That year, the climate was abnormal, and the entire mine was located at the intersection of two cold currents, so it became extremely cold. Chang'an stepped up urging people to speed up exploration, and it would be best to explore the entire mountain veins as soon as possible. This order made everyone suffer, but there was no other way, so they could only work in the cold wind.

The surface part at the foot of the mountain has been explored, but the cold current has arrived at this time. The strong cold wind has broken the branches on the mountain. The exploration team and the leaders of the special forces discussed it and decided to organize people first to strengthen the research institute on the mountain. Otherwise, the fragile walls of the research institute would be very likely to be washed away by the strong cold wind.

That night, everyone was strengthening the wall. Suddenly, a scream from a person came from the corner of the wall. Not long after, another scream from another person came. The patrolman responsible for the guarding work went over and asked what was going on. But when he went over, he saw that there was obviously no one in the corner of the wall.

The patrolman thought it was strange and reported the matter to his superiors. The captain of the garrison troops thought it was the whistling sound caused by the cold wind, and it was no big deal, so he didn't take it seriously.

That night, under the invasion of the cold current, the snowstorm began to fall. The newly reinforced wall seemed to be unable to stop the cold wind, and the fragile doors and windows were blown out several times. At this time, someone suggested to sleep in the mine next to the research institute. After all, the entrance of the mine was facing the air outlet.

Under the protection of the construction vehicles, everyone moved into the mine torch. It was said that it was a mine, but in fact, it had not yet started mining at that time. It was just a shallow hole, which was only a few dozen meters deep at best. It was able to contact the mine veins just now. But this depth was enough to accommodate everyone. Everyone put the mine cart and other facilities at the entrance, and then moved the camp bed and other facilities in.

But shortly after moving in, everyone discovered that there was one person missing.

The missing person was the patrolman who had reported someone screaming before. Since it was not his turn to be on duty that night, everyone thought it was very strange. But the wind and snow outside were too heavy, and no one was willing to go out to search, so they could only wait until the wind and snow stopped before talking.

At that time, the people from the exploration team and the people from the garrison were sleeping in chaos. Everyone was cold and sleepy, and no one cared about anything. They just slept until dawn. When they woke up, they found that there was one more missing.

There were two people missing, and the wind and snow outside were getting less and it was too unreasonable to not go out to look for it, so everyone organized a search team to go out to find it.

But as soon as I was about to exit the cave, someone felt something was wrong because there was no footprint from the cave entrance to the outside.

Although the snow outside is strong, at least a little trace should be left. In order to keep the cold at night, everyone stuffed stones at the entrance of the cave. Now the stones have not been moved away and there are no footprints outside. How did the two missing people leave?

Uneasy began to spread among the crowd, and some of them said, "Will it still be in the hole?"

So everyone searched in the cave again, but in the deepest part of the mine, two new lines of footprints were found, and the footprints were walking in.

The footprints stopped in front of a small hole and disappeared. Some geologists went over and looked at it and believed that the small hole seemed to be formed by erosion. The water containing erosion is flowing here, and over time, a hole is eroded.

But such a small hole can't even fit into the arms, so it's obvious that someone could get in.

At that time, there was a man named Han in the exploration team who was specifically responsible for the rescue work after the mine accident. Everyone called him Lao Han. Lao Han found a device that could detect life reactions and measured them in front of the small hole, and actually detected a life reaction in the hole!
