My Father in Law is Lu Bu

Liu Mang, who was participating in a cosplay event, accidentally traveled to the late Eastern Han Dynasty while wearing the Aries Gold Cloth (Saint Seiya!).

He appeared on the city wall just as Cao Cao was attacking Lü Bu and Xiapi was about to fall.

"Big bro, don’t kill me, I’m not one of Boss Cao’s men!"

"Hey hey, you’ve got the wrong guy, Lü Boss’s men are over there, I’m not one of them!"

By accident, he rescued Lü Bu, who had been tied up by Song Xian and Wei Xu.

By accident, he became Lü Bu’s son-in-law.

By accident, he changed the course of Three Kingdoms history.

When twelve sets of aluminum-plated Gold Cloth armor sparkled on fierce generals like Zhang Liao and Gao Shun in the late Eastern Han era...

When every soldier in the Camp of the Valiant was armed with a mechanical repeating crossbow...

When hybrid rice was being cultivated across Lü Bu’s territory...

Liu Mang knew that a world belonging to the Lü clan was about to arrive.

Time traveling between the Three Kingdoms and the modern world — a different Three Kingdoms, a different life.
