The Legend of Qin: As a Guard, I Am Protected by Yan Fei

Transmigrated into the Qin Dynasty as a nameless guard, I encountered the first extraordinary woman of the Yin-Yang School vomiting blood and collapsing while I was on night watch. I'm just an ordinary person, but the System gave me only one option: save her. When Donghuang Taiyi personally led people to kill me, Yan Fei shielded me behind her. She said, "From now on, I'll protect you."
