This System's Rewards Are a Little Too Generous

Warring States novels are always about samurai or commoners unifying the realm. But has anyone ever written about a ninja unifying it?

Xiaotou was originally a shut-in from a later age. Then, for no apparent reason, he ended up in the Warring States period as a ninja named Danzang, carrying a System called Fifty Years of Life. Thus began his quest to rise to power and contend for supremacy.

Make deals with samurai and daimyo? Not a chance. If a daimyo sends ninjas to attack me, I strike back. And so Danzang's ninja forces grew ever stronger, until he became the ruler of the realm.

This is a novel about ninjas in Japan's Warring States period. Please feel free to point out any shortcomings.
