A young forensic scientist from the 21st century transmigrates into the Tang dynasty and awakens the Imperial Tutor System. At first, he keeps his head down, but after a powerful clan ambushes him on the road and he nearly hurts Little Xi, he finally shows his true mettle: taming floods, crushing bandits, forging firearms, and training a navy.
Xue Rengui becomes my personal guard, and the sons of the great families all submit to my discipline.
With one hand, I forge iron to shape the fate of the nation; with the other, I protect the woman I love.
I will not kneel to the throne, nor bow to the aristocratic clans.
In this age of prosperity, I call the shots!
