In the game, an express delivery was sent to the mailbox in front of the ranch house.
Qin Lin knew that the results of professor Gao's research had come out, so he had sent the cosmic particle ray technology to the ranch.
To put it simply, this technology was the particle ray technology.
More importantly, many of the weapons on earth should fail in space. Let's not talk about whether they could be launched or not. Even if they could be launched, there would be a huge problem.
In space, a weapon was like a vacuum flask. After firing a few shots, it would have to wait for a long time before it could be used again.
Another big problem was the recoil. After firing in space, if the bullet did not hit the target immediately and the speed of the bullet was reduced, then everyone, including the shooter himself, could become the target of the bullet. Therefore, firing in space was likely to be the beginning of suicide.
