Three Kingdoms: I'm Zhao Yun's Brother-in-Law, and My Master Is Zuo Ci

Also known as “My Master Is Zuo Ci: From the Start, I Take on Lu Bu Head-On” and “Zhao Yun's Brother-in-Law: From the Start, I Defeat Lu Bu” Yang Ze transmigrates into the Three Kingdoms era and is betrothed to Zhao Yun's older sister as a child. At five, he becomes Zuo Ci's disciple. At eighteen, after coming down from the mountain and completing his training, he encounters Huang Zhong, who is desperately seeking a doctor for his son, and steps in to treat him. They return to the village together, then Yang Ze and Zhao Yun head to Luoyang to campaign against Dong Zhuo. They arrive just as Lu Bu taunts the defenders from beneath the city walls, and no one dares answer his challenge. Zhao Yun, Huang Zhong, and Yang Feiyu join forces against Lu Bu, drive him back, and become famous overnight. Later, Yang Ze saves Cao Cao as he retreats after his campaign against Dong Zhuo fails, and Cao Cao sincerely invites him to join his cause. Cao Cao: “Feiyu, since your master is Zuo Ci, could you show us some immortal arts?” Yang Ze: “My lord, I don't know any immortal arts, but I'm good at making alchemy furnaces explode. Blowing a hole in the city wall would be no problem.” He thought to himself: Even if I knew immortal arts, I couldn't show them to you. What if you started chasing immortality?
