Return to 1990 and Become the Richest Man

Time went back a few decades and I was reborn. My mother was not crazy yet, my sisters and brothers were still young, but my father was no longer here. If I stop being a scumbag, I will honor my mother, avenge my father, and become the richest man in the world. If people respect me an inch, I will respect them a foot; if someone bullies me a foot, I will repay them a hundred feet. My father's murderer? Double your life. Master of special skills? Beat them all up. Big and small horses? Acquire them all. Joe Spitz? Direct merger. The ruthless Ding Yihang is here, and the world's richest man is here.
