Zombie: My Sister Is Ren Tingting

I traveled through time as a child and fell into a world full of monsters. Fortunately, I was adopted as my younger brother by Ren Tingting. Although it was a bit shameless to pretend to be a child, I had no worries in life and my system was awakened. Life was really enjoyable! This novel and its characters are purely fictitious.
