Zhou Fang is a seeding ship of the Ecological Engineering Corps (EEC) of the Ancient Earth Empire. It has more than 200 service personnel, including strategists, scientists, ecological engineers, crew members and officers. It can also transport 1000 soldiers, provide food for all, and run at full capacity to destroy other planets. During the war between the two sides, Heron, a slave race of Harangan people, broke the dome of Zhou Fang and entered the spaceship. The crew released viruses and monsters in the gene pool to fight it. Finally, four crew members left, one was fatally injured and two were sick. The last one wrote a weekly attack program, which placed a plague on a Harangan planet every other generation, constantly radiating the gene pool, making it mutate and crashing to haviland.

Haviland Taft was hired by four people who wanted to find treasure from Harlan Gump's planet to study the Cataclysm. After boarding Zhou Fang, the four men went their separate ways to occupy Zhou Fang, and finally died under Zhou Fang's self-defense system (air full of bacteria and viruses, biological weapons from various planets). Therefore, Tufu owned Zhou Fang and changed his occupation to ecological engineer.
