I Am the Nanny of the Villain - Chapter 49:

After transcending to a new world, Ye Xuan miraculously obtained the Swallowing System.

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.

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