Eating Melons in the Police Station - Chapter 76

In 1930s Canada, a 16-year-old landlord unlocks a System unlike anything this world has seen—a power that lets him grant supernatural abilities drawn from warriors of another realm. Barbarians, Archers, Wizards… all under his command.

Jin Runcandel is the youngest son of the greatest Swordmaster. After he gets himself kicked out of their clan, he meets a tragic fate…but before he dies, a God gives him a second chance. Now he must use his new power for good.

Xie Tao had always believed in science until one day, a meteorite smashed into his yard, forcing him to bind to a heroic world saving script. The worst thing was that the script didn’t even follow common sense.

Others become superheros while he became a super-nanny. So in his left hand was a “Cub Encyclopedia” and in the right, a small milk bottle to feed the small cub clinging onto his leg.

Today, Xie Tao is trying his best to save the world.
