"What's going on?" Liu Gan asked Jiang Jinyuan.

"There is a little bit of paper confetti here..." Jiang Jinyuan observed the eyeball for a while and found the problem. He carefully used another bunch of rolled toilet paper to gently push the piece of paper confetti away, and took the eyeball over and scanned it again.

This time, after successfully scanning, the electronic door lock sounded a horn! A few light sounds, and several lock tongues seemed to bounce out of the lock box in turn. At the same time, a gap appeared beside the iron door. It was obvious that the iron door was not pushed open inside, but was the kind that slid away to the side.

"You need to use brute force to open it. My handheld computer can only provide power to the electronic door lock, and cannot drive the drive motor roller of the iron door." Jiang Jinyuan took his eyes back and said to Liu Gan after he put the cap on the cultivation bottle cap.

Liu Gan tried to use his fingers to snatch the gap where the iron door opened, but the gap was too narrow to reach his fingers, so he could not use the upper force.

After thinking about it, Liu Gan stuffed the end of the fire axe blade into the gap, and used both hands to pull the end of the axe hammer, and pried the gap between the iron door a little wider. Now his fingers could barely penetrate the gap, so Liu Gan snatched in with both hands and suddenly added up his strength. Jiang Jinyuan also came to help. The two finally opened the thick iron door by about dozens of centimeters, enough for them to get into it.

After entering the iron gate, Liu Gan closed the iron gate back a little, leaving only two centimeters of space so that he could open the iron gate when he came back, and at the same time, he also avoided zombies coming here accidentally and sneak attacks them when they left.

After closing the iron door, Liu Gan took out the flashlight and took a look around. He quickly confirmed that there was a huge underground warehouse here, which was about six meters high. There were some very complex pipes above, and there were many shelves piled up below. In the shelves were all kinds of instruments, debris, and some huge cartons containing information.

The warehouse is not very large and there are many things piled up. Liu Gan thought that since he came in, he would look inside to see if he could find any high-tech products, medicines, canned food, etc.

After a search, Liu Gan confirmed that there was no canned food in the warehouse, and it was full of very professional equipment and documents, so there was almost no material to use. He only found a crowbar next to the wall somewhere and seemed to be useful.

"You said you can find some treasures for me here?" Liu Gan couldn't help but feel a little disappointed when he saw that Jiang Jinhara had also walked back empty-handedly.

"It's all used instruments, and there are no high-tech products." Jiang Jinyuan looked a little embarrassed. He came to this laboratory and was indeed suspected of using Liu Gan. As for whether he could find any good things, he was not sure.

At this moment, I don’t know whether it was underground or somewhere else, a very subtle rumbling sound came from. Ordinary people couldn’t hear it at all, but Liu Gan’s enhanced hearing was noticed.

"Did you hear the rumble?" Liu Gan asked Jiang Jinyuan.

"I didn't hear it." Jiang Jinhara shook her head.

"Maybe it was the thunder outside." Liu Gan speculated.

Just when Liu Gan was a little disappointed and was about to ask Jiang Jinyuan to leave together and return to the previous floor to find a backup motor, he suddenly seemed to have thought of something, so he asked Jiang Jinyuan to turn on the detection device again and conduct some detection below the ground.

After observing the detection results, Liu Gan found an abnormality on the screen of the handheld computer. It was a yellow spot of light, and the lightness was very low. If you don’t observe carefully, you can’t find it at all.

According to E Jinyuan's previous statement, green represents life without infection, red represents life with infection, and blue represents local indigenous people. So what does this yellow dot represent?

There are five minus signs next to the yellow dot, indicating that the yellow dot is at least ten meters deep underground below the warehouse.

"The yellow dot represents an unknown type of creature that cannot be recognized by the main system of the handheld computer. It should not be infected zombies or mutated zombies. If so, it will be displayed directly as red or crimson." Jiang Jinhara explained to Liu Gan a few words.

Liu Gan came to the vicinity of the yellow dots according to the instructions of the handheld computer, but found that the place where the yellow dots were located was blocked by several shelves arranged together. Before, the two of them were looking for things to pass here, but they didn't think too much about anything. Now it seems that this seems to mean that there should be a secret passage inside these shelves that can lead to the bottom of the warehouse, and this secret passage connects a secret space.

The unknown creature represented by the yellow dot should be in that secret space.

Could it be that a little wave SS is protecting some artifact? Liu Gan's mind couldn't help but turn quickly.

Without the guidance of the handheld computer, Liu Gan could not see the abnormalities of these shelves. Moreover, this underground warehouse needs to pass security checks and requires high authority to enter. Then the secrets underground in the warehouse are definitely not ordinary secrets. Since this step has come, it must be investigated clearly.

After Liu Gan moved some of the goods on the shelves, he used brute force to pull the shelves apart. There was a square space behind the shelves, and there was nothing else in the space, only a carved cylinder with a diameter of about one meter in the middle.

"What does this mean?" Liu Gan walked into the square space and turned around the carved cylinder twice.

After chopping a few axes at the carved column, Liu Gan stopped. There was a solid reinforced concrete structure inside, which looked more like a load-bearing column. Maybe there was nothing behind the shelf, just because there was a load-bearing column. It was surrounded by shelves for the sake of beauty, right?

Just as Liu Gan stepped back a few steps in disappointment and was about to leave, he suddenly felt something was wrong under his feet. So he walked around in the space behind the shelves, stomping his feet while walking.

The stomping of his feet made the ground thumping sounds. Liu Gan carefully distinguished the subtle differences in each sound. Finally, he stood near a certain floor tiles and confirmed that the sound of the floor tiles trampling was somewhat different from other places.

Liu Gan touched the gap in the floor tiles, but no abnormality was found. After thinking about it, he simply took a wall hammer and smashed it hard on the floor tiles. The floor tiles and the cement blocks under the floor tiles were smashed into blocks by the wall hammer. After moving the broken floor tiles and cement blocks, a round iron door appeared under the floor tiles and cement blocks.
