I'm One Million and Seven Years Old This Year

What!? A million years have passed while I was asleep? So am I seven years old or one million and seven now!?

What!? How did little sister Xiao Zheng grow taller than me while I was asleep? And why does she want me to call her big sister!?

What!? I became the strongest person in the universe while I was asleep!?

But my body is clearly that of a seven-year-old child!

Shen Tingzhong: an ancient monster who looks like a child but has an extraordinary level of strength!
