I Built Intelligent Armor in the Zombie Apocalypse

The coastal city of Binhai in the Great Xia Kingdom is suddenly hit by a zombie virus outbreak caused by nuclear pollution in the ocean.

Xu Bin, a mild-mannered programmer working in Binhai, had all his savings drained by his girlfriend Zhang Xinyi and her younger brother before the apocalypse. After it began, his girlfriend and her lover took over his home and supplies. Worst of all, once they'd eaten all the food, they set their sights on Xu Bin himself. And so they ate him.

But when Xu Bin wakes up again, he discovers that he has been reborn, back on the day before the zombie virus outbreak.

Determined not to repeat his past mistakes, Xu Bin seeks out Chen Peng, a college classmate who studied mechanical engineering, and together they build a set of smart armor.
