Reborn in 1990: First, I'll Ruin My Wife's Reputation

This isn't an effortless wish-fulfillment story. The protagonist won't get rich without breaking a sweat right from the start, so please don't read if that bothers you. But I don't mind people cursing me out, haha! Zhuang Guoliang: Are you sure the child is mine? Fine, I'll let you have the baby first! Then I'll settle the score with you! Zhang Yuqin: I deliberately got pregnant by my lover! What are you going to do about it?! School beauty: Guoliang, I'm single! Good buddy: Stick with you and I'll get to eat well! Government official: Mr. Zhuang, please come invest! Top-level organization: The responsibility for the country's scientific breakthroughs is in your hands! Making money is the goal. I did enough teaching in my previous life. In this life, I'll do whatever makes money.
