Tang Dynasty: Overturning the Coffin Board of Queen Changsun at the Beginning

I rescued Queen Changsun from the coffin, but Li Er thought I was blaspheming his wife. I almost got beheaded at the beginning, and this guy Li Er even threw me into jail! As a result, all the imperial doctors in the court were useless, and I was the only one who could save the queen. Inside the prison, the prince and I fought each other with fists and feet, and finally confessed our feelings; outside the high wall, Li Shimin eavesdropped through the wall, and was heartbroken with regret. No one knew that this young man whom he regarded as useless and abandoned on death row was actually his biological prince living among the people and connected by blood! You think I can only be a doctor to save lives and heal the wounded, but it turns out that this guy is Qilin'er of the Tang Dynasty!
