"Because we are human," Li Chengyi answered.
He walked step by step towards the other.
"Humans, such creatures, are always unsatisfied, always wanting more.
They have emotions and desires, impulses, they cry, they laugh, they love, they hate. Would you like a stone that never moves, that stays to keep you company?"
"That sister said something similar. I believed her, and I let her go out," Yserine said.
"Then, I never saw her again."
Her expression suddenly twisted.
"She lied to me!! She promised she would come back!!"
"She died," Li Chengyi cut her off.
He knew who she was talking about. When investigating, he had already found out about the few Blind Spot Individuals who entered Tightening Grasp before.
Before integrating other Blind Spots to form a new one, some records had been found about Yserine's individual Blind Spot, and he gradually learned some related information.
"No matter what, I won't let you out," Yserine's expression calmed down.
