Born to Wealth and Nobility

[Weibo: @Chang An Muxi Niang. See my serial and completed works in my profile.] I Luobai, the star of agricultural science, transmigrates into a cannon-fodder supporting male character in a modern urban male-oriented novel. The System orders him to follow the plot and get himself killed. The story doesn't begin for another seven years. With nothing better to do, Luobai gets to work developing agriculture and accidentally builds an agricultural kingdom. II Seven years later, Luobai, father of agricultural science, is ready to follow the plot. Luobai: Where's the male lead? System: You raised him like a piglet. III Li Yan wasn't a good person before he was reborn. Afterward, every one of his internal organs was black. Luobai alone was the only goodness in his life. Warnings: 1. Modern alternate setting. Transmigration into a book. 2. A wealthy constitution: the bone structure of someone destined to be rich. 3. The gong is dark-hearted and not a good person. He refrains from doing bad things because of the shou. 4. This is basically a farming story, with a huge golden finger. I'll do my best to avoid any major plot holes. Theme:
