Lord of the Spring and Autumn Era

One morning, he wakes up in the Spring and Autumn period and finds himself in the state of Jin, having become a minor lord.

The state of Jin had only recently experienced the ruler's call for several noble families to unite and destroy the Zhao clan.

Domestic aftershocks had not yet settled; upheaval abroad continued.

Possessed by the soul of a minor noble, Lü Wu decides that before advancing to become a great lord, he should first use the knowledge of later generations to improve his own life...

And this is an era in which a transmigrator, no matter what he does, can end up becoming an inventor by accident!
