Book: Brilliant detective

Human psychology will continue to establish a balanced relationship with the environment. When the external world is too complex and cannot be changed, the heart adapts to it and accepts it. It looks like a pumpkin crushed with iron. The inside of the pumpkin will continue to harden and become as hard as wood. If a person is imprisoned and loses all his personal freedom, and if he feels that his life is under threat, he gradually gives up his dignity for survival and pleases his captors in exchange for resources for survival.
