On the cliff above the wreckage of the Ilstar space research ship, a lunar work vehicle specially designed and manufactured for the lunar environment stopped, and the only thing that could be seen in the sky without atmosphere was a black sky full of starlight, which was a black canopy.

Xia Yu jumped from the passenger seat, came to the edge of the cliff in a strange jumping posture and looked down, it was more pure black than the sky, there was no light coming up from below at all, Xia Yu couldn't see anything. According to the data, from the top of this cliff to the location of the wreckage of the spacecraft below, the vertical height is 372 meters, and the steepest place reaches an angle of 118 degrees, and even the trail that the work car can go down is also winding, and the maximum slope reaches an amazing inclination of 62 degrees.

Xia Yu stretched out his head and glanced down, the deep dark valley was like a huge mouth of a devouring devil, and he couldn't see the bottom at all, Luo Xiang next to him also walked over to look down, and then immediately retracted back, this is completely different from looking down from the plane, just one glance, there is a feeling that can suck people into the bottomless abyss, and can only keep falling down, but can never fall to the bottom, even if he knows that the ground is more than three hundred meters deep.

"All ready?" Xia Yu turned his head and looked at the team members who were already standing behind him.

"Yes, Captain, we're all set." Ivy said, holding up the rifle in his hand. This is a rifle specially designed and manufactured for the extreme environment of the moon, although it is also gunpowder fire, but at least it can shoot in this extreme environment of more than 120 degrees during the day and more than 180 degrees at night.

"Good, set up the station as planned." Xia Yu took the sniper rifle handed over by Jin Ming and said: "Let me emphasize again, the gravitational force here is only one-sixth of that of the earth, which means that the flat throwing distance of the bullet will be extended by six times, and the shooting distance will also be extended by six times, and the shooting reaction will be completely inconsistent with the earth, so we had better try it now, so as not to mess up later." ”

"Hehe, I've wanted to do this for a long time." Ivy aimed his rifle at the empty wilderness, and was about to shoot when Xia Yu suddenly said, "Wait." ”

"What's wrong?" Ivy is unknown.

"Don't shoot at an open place." Xia Yu shook his head: "We have to confirm the landing point of the warhead and try to avoid accidents." ”

"Okay, I see, Captain." Ivy nodded, then lowered the head of the gun, and put the butt on his shoulder, the elongated design of the butt and sight were not affected by the fact that Ivy was wearing a large helmet, closed his left eye, Ivy aimed at a rock, and then "bang"......

In fact, I was exaggerating, there was no "bang" at all, because there was not even a medium on the moon that needed sound transmission. The primer of the firing pin fired the bullet, the ammunition with its own oxidizer deflagrated, and the expanding hot air dissipated without a trace as soon as it pushed the bullet out of the barrel, Xia Yu and the others could see the sparks spewed out of the barrel, and they could also see the smoke that rose and dissipated immediately, but Xia Yu and the others couldn't hear any sound, except for the "I" that Ivy shouted on the radio.

Ivy's shout of "I rely on" is purely a meaningless cry in the event of an accident, and although the specially enhanced bullet has been specially designed to reduce the recoil of a large distance, it still looks impressive in an environment where gravity is only one-sixth of the earth's. Ivy kept his stance and fired the gun, misestimating the effect of the recoil on himself, so that when he fired, he was shocked to the ground by the butt.

"Haha, Lao Chang, didn't you eat today?" Chen Yongbiao picked up the ivy who fell to the ground and laughed: "I remember that you said that there is no gun that you can't play, why was it overturned by a gun today?" ”

Ivy was a little annoyed and angry, grabbed Chen Yongbiao's outstretched hand, stood up with force, and after checking that there was no problem with the spacesuit on his body, he said angrily: "Don't laugh at me, it's the same for you, I don't believe you try." ”

Chen Yongbiao smiled: "Ha, just try it, anyway, I won't be shocked by a gun like you." ”

"That's hard to say." Ivy pressed the butt of Chen Yongbiao's gun with his hand, deliberately pushed Chen Yongbiao hard, and said: "The force I received when I fired the gun was much heavier than the two times I pushed you." ”

Chen Yongbiao smiled and didn't answer, but he was secretly prepared in his heart, he didn't want to be as ugly as Ivy, so although he aimed the same with a standing position, he probably moved more of his center of gravity to the front foot, but he didn't notice that when Ivy held the butt of his gun with his hand just now, he quietly adjusted the shooting mode to a combo state.

Xia Yu noticed this small detail on the side, but he secretly smiled and didn't make any reminders. There is still too little run-in time between him and the team members, although at this time you can use your superiors and subordinates to order the team members to be more serious, but the disadvantages outweigh the advantages, because even if the team members can strictly complete the tasks they require, they are definitely not as good as the team that can joke at will in terms of tacit understanding. In order to be able to complete the task better, Xia Yu didn't mind the team members making some jokes without affecting the task.

Chen Yongbiao, who didn't know that he was placed together, was ready to shoot, aimed at the rock in the distance, pulled the trigger, and originally thought that the center of gravity was so forward, even if the recoil was relatively large, he should be able to withstand it, but only one-sixth of his weight, coupled with an unexpected triple hit, Chen Yongbiao was shocked and lost his balance, and sat down with his ass, causing a burst of laughter from everyone around.

"Damn, you always yin me." After Chen Yongbiao pulled the trigger, he immediately understood that it must be Ivy's hands and feet, and he angrily and funny held Ivy's outstretched hand and stood up.

Xia Yu saw that the trouble was almost over, and then said: "Okay, everyone has noticed what happened to Ivy and Chen Yongbiao just now, the gravitational environment of the moon is completely different from that of the earth, and we need to confirm that we can grasp the gun in our hands before we can start the mission, so from now on, everyone will at least use up one magazine to get used to the feeling of shooting on the moon." ”

After saying that, Xia Yu himself picked up the sniper rifle, aimed at the rock and pulled the trigger. As the bullets were fired, Xia Yu finally knew why even Ivy and Chen Yongbiao, two people who had nothing to do all day long, had that kind of trouble when they shot for the first time. Including the human body itself, all the qiē has lost six times the weight, which is equivalent to a six-fold increase in the impact force of the bullet when it explodes compared to the earth, and this effect is not only a scientific calculation, but also the perception and experience of the person itself, wrong judgment and discomfort are the key to the Ivy two's troubles.

Shooting out of magazines in a row, these people are the elite of the elite, although they are not as good as the ground combat troops, but as far as the pilots and astronauts themselves are concerned, their ground combat capabilities are already outstanding, so they quickly adapted to the feeling of shooting on the moon.

After confirming this, at least after confirming that there would be no problems with everyone's first shot, Xia Yu turned his head and said to Jin Ming: "Is the lunar exploration vehicle ready?" ”

"Ready." Jin Ming nodded, put three small expedition vehicles specially designed for lunar exploration on the ground from the work vehicle, looked at Xia Yu and said, "You can use it at any time." ”

"Very well, then let's get ready to start." Xia Yu nodded and moved his gaze to the dark deep valley.
