During the conversation, the robot had already arrived at the last airtight door.

"Open this door and you can see the secret hidden by aliens." Cheng Yingnan murmured to herself. In fact, she was still a little nervous in her heart.

The robot began to cut the airtight doors according to the previous plan. These airtight doors did not use locks such as electronic locks, but made some purely mechanical door opening devices, and after closing, they could only be opened from the inside, so Mark asked the robot to choose the cutting plan.

The high-temperature laser continues to vaporize the metal gate composed of unknown alloys. As time goes by, charred marks appear on the air-tight door.

The robot accurately controls these cuts in a perfect straight line. As the straight line extends, a door frame appears, and a robot kicks forward and hard, and a hole can be inserted into and out of the airtight door that can accommodate the robot.

The robot threw away the cutting equipment in his hand, replaced it with a weapon, fired a reconnaissance ball, and then the fish entered the warehouse behind the door. As the robot entered, the situation in the warehouse also appeared in front of Li Yu and the others.

This warehouse is not big, with an area of ​​about 1,000 square meters. According to the live images sent back, Li Yu and the others found that the entire warehouse can be divided into several areas.

"This area should be a specimen area. Look, do these specimens look familiar?" Fang Qianmo said, pointing to an area in the shadow.

Fang Qianmo was right. Anyone with a discerning eye could see that it was a specimen area. There were cylindrical transparent containers, all of which were unknown liquids. All the liquids were soaked in the liquids, and some plant specimens were placed in the middle of the cylinder.

Li Yu pointed to another area and said, "This area must be the main body of this signal event and the signal receiving device."

The place Li Yu pointed to was placed in rows of unknown devices. These devices had been activated and were emitting a faint light blue light.

One of the devices is showing the coordinates of the earth, and an orbital line connects the meteorite to the earth.

"This is also considered a control center. There should be equipment similar to computers to let the robot look for it to see if the data interface can be found." Fang Qianmo said to Cheng Yingnan.

Before Cheng Yingnan could give instructions, Mark obviously realized this. One of the robots walked straight to an area similar to the control center and began to search or tentatively find the data interface.

"Create a signal isolation area for meteorites and use alien signals to test it!" Li Yu suggested.

Li Yu's suggestion made Cheng Yingnan's eyes lit up. She quickly passed Li Yu's idea to Mark. Mark did not hesitate and established a signal isolation circle around the meteorite, but it would take some time to simulate the signals of aliens.

"I'll do it. Although the aliens use super-light speed particles to transmit signals and the mode is unknown, this is not a problem for me. Give me a while!" Lin Wanbai confidently took over the problem of cracking the alien signal mode.

To be honest, the difficulty of super-light particle communication is simpler than that of Li Yu's space field communicator, one is the sky and the other is the earth.

Some time ago, Lin Wanbai happened to study the technology of detecting objects in superluminal flight, and he still has some experience in the research on superluminal particles.

In addition to areas similar to control centers, the main area of ​​this warehouse should be the storage area. The most conspicuous thing in the storage area is dozens of things like barrels. The material of the barrel is an unknown alloy material, and the water vapor emitted around it indicates that their temperature is very low.

There are also alien characters and code-like numerical codes written on the barrel.

In addition to the above things, there are other things in the warehouse, but it is not very important to not look at them. They are a bit messy when placed, and it seems that the owner of the warehouse doesn't value them much.

"These barrels should be aliens' tools for the earth, right?" Fang Qianmo pointed to the barrels in the shadow and said to Li Yu.

"I want to take two round barrels and send them back to Earth with an unmanned spacecraft. I want to study them." Li Yu said to Cheng Yingnan.

This is not a problem, but only an hour. So Mark asked to send a robot from the spaceship, load two barrels with an extremely sealed container, and express it back to Earth by unmanned spaceship.

"There is no external monitoring equipment, and the energy of the base is a small reactor. According to preliminary detection, the construction time of the base in this meteorite will not exceed three thousand years."

"This meteorite base should be in a dormant state after it is completed until it was activated by an alien signal not long ago, so the alien signal has a great possibility that it only contains activation instructions without unnecessary content."

"The only strange thing is how the aliens are sure that this meteorite base can still operate?"

Mark was summarizing and reporting to Cheng Yingnan, "This warehouse or base has a very single function and seems to exist only for a purpose, which is to release something on the earth."

"Wait, Mark! Release something, how did you come to this conclusion?" Li Yu interrupted Mark's report.

"This is our speculation, but the most likely one is. We have established a model, which is the level of the earth's technological level without us and the influence of the laboratory when meteorites hit the earth."

"Based on this model and what we found on meteorites, we found that this meteorite actually does not have a great threat to the earth. At best, it is just to let the earthlings enjoy a grand meteor shower."

"So, did the aliens expect this situation? It means they had expected it from the fact that they arranged this meteorite in the solar system in advance."

"Then, this meteorite is not the main means for aliens to take action against the earth. Then we established thirty possible means that aliens may take. Among the ten most likely types, this meteorite exists as a means of transportation."

Li Yu nodded, Mark and others did an interesting thing, establishing a model for the earth, then inputting conditions, and deriving the results.

This is a method that Li Yu and the others had never thought of before. Of course, Li Yu and the others did not need such trouble.

"Very good, keep working hard and try to investigate everything on this meteorite clearly. We must find out what the purpose of the aliens is!"

“We will.”

"It seems that your team members are growing very fast, which is very useful!" Li Yu said to Cheng Yingnan.

Li Yu's praise made Cheng Yingnan very happy: "Of course, my team members are all rare geniuses in human history, and with almost no adventures in human history, it would be strange if they failed to achieve success."

Lin Wanbai walked over staggeringly: "Okay, the aliens' communication mode has been cracked. Now the only problem is their communication content. I can't solve this."

"It's already good. Xiao Wei, let the Earth Manufacturing Center create the corresponding equipment and send it to Mark and the others!"

"Okay, let's arrange this." Xiaowei began to arrange tasks, with detailed manufacturing plans, and the Earth Manufacturing Center could easily create anything.

No new discoveries were found on the meteorite for the time being. After the unmanned spacecraft sent two barrels to Li Yu's hand, Li Yu and the others left the deep-sea base.

Li Yu did not study these two barrels on Earth. He went to Moya Base, which is the best research location. No matter what accidents occur, it will not affect the earth.

Everyone in the Moya base came to Li Yu's laboratory, Xiao Wei, Mo Ya, Fang Qianmo and Lin Wanbai, all of them came.

They were all interested in what was inside the barrel.

To study the things in the barrel, Li Yu must first understand the materials of the barrel. This is not difficult for Li Yu. His old profession is material research.

The equipment for studying materials is very complete, and Li Yu quickly understood the material of the barrel. The main elements of the material or alloy are common elements, including some rare elements, including one elemental variant, which Li Yu has never seen before.

Overall, this alloy has extremely low density, less than 2, but has extremely poor thermal conductivity and is extremely strong.

After knowing the composition of the barrel, Li Yu can detect the internal structure of the barrel in a targeted manner, which does not take much effort.

After ten kinds of things, Li Yu got the internal structure diagram of the round barrel. Looking at the projected internal structure diagram of the round barrel, Li Yu said thoughtfully: "It seems that these round barrels are a storage container, and is there liquid stored in it?"

"It shouldn't be liquids, they just look like liquids." Fang Qianmo also looked at the Shadow.

"Have you found the way to open it? Open it, don't you know what's inside?" Lin Wanbai had no patience to guess.

Li Yu carefully studied the structural diagram of the barrel. After a while, he said: "We should find a way to open it."

After saying that, Li Yu put the barrel into a sealed space, then sent a robot in, and then turned on the remote control mode.

The robot stretched out his finger and gently pressed a pattern in the center of the top of the barrel. The barrel found a sound of gas leaking, and then the top of the barrel rose.

Water mist emerges from the inside of the round barrel. When the water mist disappears, things inside the round barrel appear in front of Li Yu and the others.

The thick bucket walls protect ten unknown liquids with light redness.
