In fact, the other gangs of the battle corpse sect would send people to the battle corpse sect every year, and the people they sent were mostly sect members with mediocre strength. However, because the other gangs had a lot of people, no one paid attention to them.
The Japanese gang had too few people, but every member of the gang was an elite. They couldn't bear to send these people to the battle corpse sect to become corpse slaves. So, the Japanese gang thought of an idea. They said that they could let ten people enter the battle corpse sect every year. This way, they could attract a large number of cultivators to join the battle corpse sect. They could then choose some of these cultivators and send them to the battle corpse sect to become corpse slaves. And it wouldn't harm the strength of the gang.
