The next time Renji returns, he finds that there is another secret base. The number of genetically-altered humans is much lower, and the research projects are much less. Renji asks a few people about this new secret base, and they tell him that the cyborgs are being sent there to protect "the big shots" . The place is full of loopholes and burning star can easily get in. The bullet that killed Hu also had a special tracking device, but the bullet stayed in the corpse for only a few hours, and it still helped them find the general location of the base. They are all being watched, so Renji is going to let them die again. There is a secret passage there, left by the former scientist who stole the medicines, now only Renji knows it. He thanks jack for arranging a bomb and corpse, and he tells Renji that he will pretend to die in Renji's place. He explains that the corpse is complicated and the medicines complicated, so it is difficult to figure out who died in the first place. The plan is to hold Renji and shoot at his flak jacket, so he can shoot Renji twice if necessary, and Renji explains that he understands. He asks if he is still part of Lin's plan, and whether he is being tricked by Lin as a pawn. He says that from the beginning, they were strangers, and that he could also be using Lin to save his sister,
