The Mathematician from a Poor Family

A madman on the left, a genius on the right.

Chen Ze transmigrates into the body of a down-and-out scholar in the Great Xia Dynasty...

All he wants is to farm and build a stable life, but bandits run rampant and foreign nations keep invading...

If Qin crossbows can’t solve the problem, bring out the rifles!

If siege engines can’t do the job, then it’s time for cannons.
