At the end of the year 2800, the earth was invaded by alien parasites. Human beings were parasitized and turned into puppets. The only remaining survivors hid in the genetic protection zone to survive. {Lu Yan} As a genetic researcher, armed with the only "gene detector", he developed a powerful anti-parasitic agent in the desperate situation of shortage of anti-parasitic agents and doubts from high-level officials. He teamed up with mechanic Su Rui to form a team of survivors, raided the parasite's stronghold to obtain genetic samples, and gradually located the parasite's mother nest. Faced with the pursuit of the leader of the parasitized former protective zone, Lu Yan led the team to break through the defense line of the brood, injected the ultimate potion to destroy the brood, and finally allowed humans to regain control of the earth.
