After the black rain fell, the "black particles" of alien life began to parasitize humans.
Most of the hosts will lose their minds and become monsters; a few people can achieve symbiosis with the black particles and gain superpowers, and are called "symbionts".
The protagonist Chen Mo was supposed to die from the infection, but he reawakened because of a special "matrix core". A second heart grew in his body, and he also had the ability to read, analyze and copy life.
As the investigation deepened, he gradually discovered:
The so-called alien invasion is actually an escape from civilization spanning thousands of years.
The black particles are not complete alien creatures, but the life information left behind after a certain advanced civilization was destroyed. They come to the earth to find new species that can carry their civilization consciousness.
Humans are both the invaders and their chosen successors.
The ultimate question in the story is not "how to destroy alien creatures", but:
When humans must change themselves to survive, at what point does it change before humans cease to be human?
Interesting, saved it
