Great Tang: After I Became Crown Prince

Another son who traveled through time and became Li Er. Ha ha! If you ask me, just travel through time and become Li Er. Then when he was caught in a trap, his son became stronger in the system. As long as you cheat your son, you will be rewarded. Whether it's the prince, Li Tai, Li Ke, Li Zhi, etc. Even if it's the illegitimate sons of another time traveler, or the consort. After all, the prince-in-law is half a son. Damn it, my son didn't discuss it. Hahaha! It's a pity that I'm not good at writing. Otherwise, I would have written it. There was an author who wrote a novel with this idea before. In the end, I only wrote 40,000 words, and it took me more than half a year. Well!
