If You Don't Care About My Three-Year Pledge, What Will You Regret If I Turn Against You with My Evil Plan?

Qin Yu traveled through ancient times and found himself in an enemy camp. It turned out that his body was the illegitimate son of the Marquis of Zhenbei, and was sent to Beirong as a hostage. But the Marquis of Zhenbei took the opportunity to make a sneak attack, seriously injuring King Beirong. Princess Beirong wanted to cut him into five pieces. Qin Yu got wise in his desperation and saved himself at the critical moment. After gaining the trust of the other party, he turned his attention to the south, and used poisonous tactics time and time again, and defeated Zhenbei Hou. Seeing Qin Yu's troops approaching the city, his father regretted abandoning him. Qin Yu sneered: If you don't care about the three years of hostage, what will you regret if I turn against you with my evil plan?
