Brother, Why Are You Rebelling?

On his way back to his fiefdom, the Fourth Prince, who was vying for the throne, is ambushed by assassins sent by his newly appointed Crown Prince elder brother.

Struck by an arrow, he falls into the water.

Li Qi, who has transmigrated from another world by chance, takes over his body.

After Li Qi reaches the fiefdom,

he faces suspicion,

so he chooses to bide his time.

He makes cement, smelts steel, and improves firearms.

When he becomes richer than the country itself,

he chooses to march back to Chang'an.

After returning to Chang'an with an army of a hundred thousand,

he stands outside the city wall and points at his elder brother's nose.

"Elder Brother, why have you rebelled?"

"This prince is only clearing the court of corrupt officials."

He demotes the emperor to Retired Emperor,

and from then on embarks on the road to supremacy.
