When Jiao Bai summoned a fourth-level zombie slaughterer, he found that this guy was not affected by the harsh environment of the moon at all, and he could still move freely and even release his skills. Jiao Bai summoned level 5, 6, and 7 zombies, which were also alive on the moon.

"It's okay, it's okay, zombies don't need to breathe oxygen, zombies above level 4 can move freely on the moon, and then try summoning beasts."

Next, Jiao Bai summoned several summoned beasts of different levels in a row, but unfortunately, none of them could adapt to the environment of the moon. It turned out that the summoned beast still needed to breathe air to survive, and even the most powerful seventh-level summoned beast he could summon now only lasted more than ten minutes on the moon before he was suffocated and deprived of oxygen.

Now that the test has a result, it's time to work, Jiao Bai beckoned, and hundreds of zombies above level four appeared in front of him, carrying stones outward. These are some ordinary zombies who don't wear human skin, crooked melons and cracked dates, green-faced fangs, everything, a scene of a group of demons dancing wildly. However, although these guys have a tendon in their brains and can't do complex things, they are good at doing some rough work, and many zombies worked together, and it only took less than ten minutes to move all the stones.

After the stone was removed, the gate of the helium three refining factory inside was revealed, which was a metal gate cast from blue-gray alloy, with a height of more than four meters and a width of three meters.

"This door is powered by electricity, and now that the power is out, we can't open it from the outside. However, this is only a cargo channel, and there is a passage for people to enter and exit next to it, which can be opened manually. ”

Cheng Ziming is very familiar with the structure and layout here, after all, he has worked on the moon for a lot of time before his death. Although it is not in this mining base, the design of the base established by Daming on the moon is mostly the same, and if you understand one, you can understand the others.

Cheng Ziming led Jiao Bai and Duan Junfeng, bypassed the freight gate, and walked a short distance to the side, and sure enough, a small gate that only allowed one person to pass through appeared. It's just that there is no handle on this door, a keyhole or something, only a password input keyboard, and now there is no power supply in the whole factory, I don't know how to open it.

As if guessing Jiao Bai's worries, Cheng Ziming patted on the wall next to him, and quickly found a well-hidden hidden compartment, and after opening it, there was a device like a steering wheel inside. Cheng Ziming held the "steering wheel" with both hands and rotated, and explained to Jiao Bai in a loud voice,

"This is an emergency manual door opening method prepared in case of a power outage. Fortunately, the power has been cut off here, otherwise this device will not work in the power-on state, and we don't have a password to open the door, and if you want to open the door, you will have to work a lot harder. ”

As the "steering wheel" turned, and after a creaking sound of mechanical transmission, the small door slowly opened. Jiao Bai and the three of them got into the small door and found that there was a small airlock cabin inside.

"I don't know if the air in the helium three refining plant still exists, let's go through the regular procedures."

After that, Cheng Ziming followed the normal steps of entering and exiting the airlock cabin, first closing the small door for the three people to come in, re-locking it tightly, and then manually opening the air pressure balance valve. In a burst of "snort" deflation, the pressure in the airlock rises rapidly until it reaches an atmospheric pressure, which is not the end.

Jiao Bai took out an air composition detector from his personal space, opened it, checked the readings on it, and said: "At present, the helium three refining plant has not broken the loss of pressure, and the air composition is generally normal, which can be used for people to breathe normally." It's just that there is no power supply, the air circulation system can't work properly, and after a long time, I'm afraid that the oxygen will be insufficient. ”

"What's the matter, we only have a sir, you need to breathe normally, and you can't consume much oxygen. By the time we get to this point, we'll be emptying this place. ”

Saying that, Duan Junfeng had already begun to take off the extravehicular spacesuit, and Cheng Ziming had begun to take off the spacesuit. Just after seeing Jiao Bai's experiment, they knew that zombies above level 4 could fully adapt to the environment of the moon, and they wanted to take off this bulky spacesuit. It's just that the moon has no air and can't transmit sound, so I didn't take it off for fear that we wouldn't be able to communicate with each other after taking off the spacesuit. Now that there is air in the helium-3 extraction plant, there is no need to worry.

Jiao Bai thought about it, he only breathed by himself, and the air in such a large factory was afraid that it would be enough to use for several months. Thinking of this, Jiao Bai no longer hesitated, and also took off his extravehicular spacesuit.

Without the shackles of the spacesuit, Jiao Bai suddenly felt a lot more relaxed, moving his arms and feet, and he was also a lot more flexible. Duan Junfeng, who was the first to take off his spacesuit, had already begun to turn the winch and open the small door leading to the inside of the factory.

After entering the door, there was no lighting system that came with the spacesuit, and the surroundings were plunged into total darkness. Jiao Bai took out three charging miner's lamps from his carry-on space, handed them to Duan Junfeng and Cheng Ziming, and took one for himself.

With the illumination of the miner's lamp, Jiao Bai finally found that the location they were now in was a long corridor, and there was a small door not far from one side of the corridor, on which were marked with signs of different colors such as "lounge", "canteen", "recreation room", "laboratory", "helium three storage room" and so on.

Seeing this, Jiao Bai said with a smile: "This is good, everything is clear and clear, let's go to the helium three storage room to see, how much we can gain from this trip to the moon depends on how much stock there is inside." ”

Jiao Bai led the way, and the two astronaut zombies followed. Originally, the distance was not too far, and the three of them only walked along the promenade for five minutes before arriving at the location of the helium three storage room. The door is still a coded electronic door similar to the entrance of the factory, Cheng Ziming is familiar with the door and finds the secret grid from the wall next to him, and rotates the winch to open the door.

After entering the door, Jiao Bai swept it with the miner's lamp on his head, and he was stunned by the sight. I saw that the huge warehouse of thousands of square meters was full of brown cylinders, row by row, stack, all the way to the roof of six or seven meters high, densely crowded together, and even the middle aisle took up a lot.

Jiao Bai swallowed his saliva and said, "I'm afraid there are hundreds of thousands of cylinders here, are they all filled with helium-three?" Is the output of this small helium triple extraction plant so large? ”：，，，
