Pei Xian, who looks like the green tea and white moonlight of Big Boss in the book, was forced by Zhou the First Gongzi to kill his child and send to the villain Big Boss as a substitute lover. Pei Xian would rather die than submit that he jumped from the building to his death.

When Shanghai’s Great White Shark Si Yang was only 28 years old, he died of illness and transmigrated as the cowardly and timid cannon fodder Pei Xian, airboned in confusion on the scene of the jump off.
