The Sui Dynasty's God of War: Yang Guang's Illegitimate Son

Lin Luotian, a modern history expert, unexpectedly transmigrates to the final years of the Sui dynasty. Worse, he ends up in a poor family as a ten-year-old child. With no other choice, he has to lie low and grow stronger.

What? I’m actually Yang Guang, Emperor Yang of Sui’s illegitimate son?

What kind of ridiculous joke is this?

The female knight I meet turns out to be Yuwen Chengdu’s younger sister! Good grief, what is going on with this world?

You want me to change history?

You damn System, I’m not even an adult yet. Don’t give me such a grand mission, okay? I just want to lie flat and be rich enough to eat and drink without a care~
