When he was weak, he would do everything possible to please his superiors, like Liu Futong and once Han Shantong. Whether it was performing dangerous tasks or anything else, as long as he could gain his superior's approval, he would do it even at the risk of dying, because he wanted to climb up.
And that is why he was willing to risk his life, infiltrating the court to act as an undercover agent in those years.
Everyone knows that the end for undercover agents is never good, but he, Du Zundao, was willing to fight.
Because only by fighting can one have a future. It also relates to his upbringing; his parents passed away when he was young, and he was fostered in his brother and sister-in-law's home, where they treated him with great hardship, always beating and scolding him. This made young Du Zundao suffer great disdain in the Mortal World and taught him to observe expressions and climb up.
