Sui and Tang Dynasties: I Am the Illegitimate Son of Tang Emperor Li Yuan

As a time-traveler, Li Fan had neither a system nor a strong body. Just when he was worried about finding a foothold in the Sui and Tang Dynasties when heroes coexisted, he discovered that he was Li Yuan's illegitimate son. The most terrible thing was that Li Yuan seemed to have no ambition at all. In order to prevent history from being rewritten, and for his father to successfully become Tang Gaozu, Li Fan went further and further on the road of rebellion...
