After the Demon Empress Forced Me into a Political Marriage, I United the Grasslands and Became the Heavenly Khan

Li Zheng, a prince, was sent to the grasslands by the Demon Empress to marry for peace, while his family's empire was usurped. He immediately activated the Weapon Modification System, turning paper into iron and glue into welds, then grabbed an AK and opened fire.

The Lu clan sent men to silence me?

"Come on, bring out this prince's modified army!"

An eighty-year-old granny leaps and bounds, while a seven- or eight-year-old kid kills a bull with one punch.

After several years of building his power on the grasslands, Li Zheng unified the Turks and became the Heavenly Khagan. He returned to the capital in planes and tanks and beat the rebel Lu clan until they knelt and begged for mercy.

"In the end, this realm still belongs to the Li family!"
