Voltaire said that the differences between human souls are far greater than those between their appearances. A disability of the soul cannot be seen.

Chu Jianglai is completely unashamed of this: "That's right, I am indeed spiritually disabled. Chu Qiubai, why don't you be my prosthetic limb?"

He lies without blinking and "kills" without shedding a drop of blood.
He says: "Chu Qiubai, it’s not Buddha you’re worshipping—it’s your own desire. And your desire lies in me. Better to beg me than to beg Buddha."

Car accidents, the death of a father, kidnappings...
Chu Jianglai is a genius, a "bad seed," and a monster sent by the heavens to subvert everything in Chu Qiubai’s life. He seizes all of Chu Qiubai’s love and hate, and possesses the entirety of his forgiveness.

The love is rebellious and unorthodox; the hatred is a bloody, mangled mess.
There has long been a cure for this sickness, but he simply refused to get well, forcing it to fester into a secret, incurable chronic disease.
