Huang Changming, the commander of the lunar base, is a sturdy man in his forties, and he is also the first commander to land on the moon and establish a lunar base.

The landing module is only more than 300 meters away from the lunar base, in other words, Xia Yu and the others have already walked directly, or even ran to the lunar base, but this is the moon, and the gravity is only one-sixth of the earth, before adapting to the gravitational environment of the moon, Xia Yu and the others need to be careful, even if the originally heavy toolbox is light in their hands at the moment, Xia Yu still asks everyone to wait for the pick-up and drop-off of the work car.

The sand on the lunar surface is very fine and sharp, and if it is an old-fashioned spacesuit, as long as you walk on the lunar surface, the expensive spacesuit will be forced to be scrapped, because it is very likely that the spacesuit will leak after many walks, even if it is a newly designed spacesuit, in order to prolong the service life and just in case, you still need to be extremely cautious. Everyone, including Xia Yu, clearly knows that this is the moon, a beautiful and deadly desert planet.

Under the landing module, Xia Yu and the others, who had just finished contact and were waiting for the work vehicle of the lunar base, began to try to walk on the lunar surface, and their suddenly lighter bodies made the feeling of walking completely different. The simulated water tank training in the Beijing Aerospace City Astronaut Training School, no matter how close the astronauts' gait is to the lunar surface, cannot be compared with the real lunar gravity environment after all, and Xia Yu and others still need a certain amount of time to adapt.

Just when Xia Yu and the other six people were jumping around, Huang Changming had already walked out of the command cabin and boarded the lunar work car, and then in the eyes of Xia Yu and others, he drove over here silently, with the sound of his own breathing, he actually had the feeling of watching a 3D silent movie. After a while, the work car had already driven in front of Xia Yu and the others, and the six of Xia Yu stopped adapting to the action, and watched Huang Changming jump out of the work car.

"Hello commander, I'm Xia Yu, the leader of the search and rescue team." Xia Yu raised his right hand and gave Huang Changming a military salute, so that Huang Changming, who had not used a military salute for a long time, was stunned for a moment before reacting, raised his hand and saluted back and said, "Colonel Xia Yu, hello, I am Huang Changming, the commander of the Moon Base." ”

Xia Yu put down his saluted hand, then pointed to the members of the search and rescue team, and began to introduce his team members to Huang Changming: "This is the spacecraft pilot Luo Xiang, the medical officer Liu Xiao, the equipment maintenance officer Jin Ming, the weapon operators Ivy and Chen Yongbiao. ”

The team members introduced by Xia Yu saluted Huang Changming, and Huang Changming replied one by one and said: "Get in the car first, and I'll introduce the details to you after you get to the base." After speaking, Huang Changming helped move all the tools to the work car, and then let Xia Yu sit in the passenger seat, and the other team members sat behind the car and drove towards the lunar base.

Soon, the work vehicle came to the complex of buildings at the lunar base. The complex of buildings at the Lunar Base is not an exaggerated fortress-like structure, but rather a circular metal channel that connects dozens of space chambers of various sizes. Some of these space capsules were sent as a whole, and some were assembled later by the staff of the lunar base, but most of the basic structures are semi-circular and semi-elliptical, and Xia Yu and others did not see a typical square structure building on Earth.

In front of a cabin, it was a metal chamber about seven or eight meters wide and almost three meters high, which looked like a huge bowl that was buckled upside down. After Huang Changming jumped out of the work car, he came to the circular sealed door in front of the cabin, turned the latch to open the hatch, Xia Yu and others saw that there was a light in the cabin, but there was nothing inside, and the surrounding metal bulkheads reflected white lights, which were very bright.

Rushing in, Huang Changming closed the hatch again, confirmed the seal, and explained to Xia Yu and the six people: "This is the No. 1 air pressure chamber, there are two such air pressure chambers, and the other one is at the other end. At the same time, every two compartments have a small baroroom that can accommodate up to two people. After seeing Xia Yu and the others express their understanding, Huang Changming saw that the pressurization indicator light turned green, so he opened the passage door into another cabin and walked to the cabin with Xia Yu and the six people.

"This is the lunar walking preparation module." After Huang Changming signaled that everyone could take off the spacesuit, he took off the helmet and took off the extravehicular walking spacesuit, and said: "Before going out, we will change the extravehicular spacesuit here, and each cabin has an independent feeding and emergency life support system, which is in that closet." Huang Changming pointed to a wall cabinet labeled with emergency supplies and said: "Emergency closing valves, backup energy, food and medicine, and oxygen concentrators are all inside, and they can only be used in case of accidents." ”

Xia Yu and the others said they understood, and at the same time took off their spacesuits and hung them in another closet, and after everyone was ready, Huang Changming continued to walk to the next cabin. And the next cabin is no longer like the previous two straight-through cabins, but the four-way cabin, that is, there are passages to the other cabins on the front and back, Huang Changming explained: "This is the personnel assembly cabin, the one on the left is the equipment storage cabin, the one on the right is the test cabin, and the front is also the test cabin, and the command module of the lunar base has to go through three more cabins to arrive." After speaking, Huang Changming pointed to the schematic diagram on the bulkhead and said: "This is the structural diagram of the lunar base, each compartment is in the same place, you can understand the basic situation of the lunar base according to this structural diagram, and avoid getting lost." ”

Xia Yu nodded, and then said to the members of the search and rescue team: "Ivy, Chen Yongbiao, Jin Ming, the three of you will deal with our equipment first, Luo Xiang, Liu Xiao, you help them take a hand, and gather in the command cabin in twenty minutes, understand?" ”

"Understood." Luo Xiang and the others nodded, and Xia Yu walked towards the command cabin with Huang Changming.

Coming to the command cabin, after Huang Changming and Xia Yu both sat down, Huang Changming said: "Colonel Xia Yu, thank you very much for coming up urgently to support, to be honest, this thing is too weird, until now, I still can't understand what happened to make my team members disappear silently, you must be careful when you go to check." ”

Xia Yu nodded in understanding, and then asked, "Is it possible that the missing team members are still alive?" ”

"No way." Huang Changming's resolute face showed a trace of grief, and said: "The two groups of team members are mission plans to return on the same day, so they didn't carry food, and there has been no news for so many days, so they won't be able to carry it." ”

"Well, I understand, please mourn." Xia Yu was comforted, and then asked, "Has the wreckage of that alien spaceship been in any abnormal condition in the past few years, including power, power supply, signs of activity, etc.?" ”

"No, that's why we're going to be comfortable researching the spacecraft." After Huang Changming finished speaking, he pressed a button on the workbench, and an electronic map suddenly appeared on the screen, and then Huang Changming said: "This is the map of the moon we draw, the location where the alien spacecraft crashed is in a deep valley twenty-three kilometers northeast of the lunar base, with a vertical height of 372 meters, and the work car can go down, but the slope is very steep, and you need to drive carefully." ”

Clicking on the location of the spacecraft on the map with his hand, Huang Changming said: "The alien spacecraft is rectangular as a whole, with a length of 417 meters, a maximum diameter of 182 meters, narrow at both ends and large in the middle, this is a photo." ”

Huang Changming clicked on the touch option on the side of the screen a few times, and then dozens of photos popped up, all of which were spacecraft photos taken by former expedition members of the lunar base. Xia Yu casually clicked on one of them to see that it was the photo of the location of the crack in the previous section, and then said in his mind: "Starry sky, is this the spaceship you carried over?" ”
