I'll Protect the Chancellor and Raise the Female General

I brought a gene sphere to the Three Kingdoms era. When Zhao Yun was close to death, I turned him into Jiang Wei. Before Zhuge Liang died of illness at Wuzhang Plains, I changed his fate too.

A man who did not belong to this era protected them from the fates that should have claimed them, hidden in the shadows beyond the reach of the history books. Later, a girl became his blade. After that, Guan Yu's daughter, Zhang Fei's daughter, Lü Bu's daughter... became his swords as well.

Then he discovered that someone had already used the same future technology to take the throne of Wei before him.
