Sui War God: Yang Guang's Illegitimate Son

Modern history expert Lin Luotian accidentally traveled through the late Sui Dynasty, and also into a poor family. He was still a ten-year-old child. He had no choice but to grow up. What? Am I actually the illegitimate son of Sui Yang Emperor Yang Guang? What kind of ridiculous joke is this? The heroine they met turned out to be Yuwen Chengdu's sister! Darling, what's wrong with this world? Want me to change history? Goubi system, I'm not an adult yet, don't give me such a grand task, I just want to lie down and be a rich man who doesn't have to worry about food and drink~
