Parasite from Outer Space

"Black technology" originally referred to scientific and technological achievements that were not developed by humans, surpassing current human technology and understanding, and even violating natural principles without a scientific basis. Such technology that transcends time, when used well, can advance human civilization, but when misused, it can destroy civilization.
Chen Yang, who is infested by an extraterrestrial creature, was once an ordinary human on Earth. Now he faces a problem: how should he use a technology that surpasses the current level?
However, before that, he has to face another issue. The extraterrestrial creature parasitizing him is not an easy companion to live with. In fact, even the worst criminal could not describe its evil.
The attitude it holds towards humans is related to the future of mankind. No matter for his own sake or all of humanity, the first thing Chen Yang has to learn is how to live with an "alien".
