"That's the nature of Uncle Zhang's work. He studies science and has made great achievements. It was he who proposed the plan of space migration. He also found those materials from the extraterrestrial meteorite and refined them. As for what he had come into contact with... He deals with some extraterrestrial things every day," Myles explained after thinking for a while.
"That's right." Jacob said, "The meteorite comes from the depths of the universe, and no one knows where it is really from. With the current defensive means of the earth, no good protective equipment can block these. Moreover, humans in the universe are weak beings. A little carelessness will kill them."
"Do you have any other way to deal with Uncle Zhang's situation?" Myles asked.
"It's not a big deal. I told you before I came that those medicines could be used on him, but it's definitely not enough to cure him. At least 2 or 3 medicines will be needed," Jacob said.
