Mr. Yin Yang of Wangbatun

Hello, I am Mr. Yin Yang from Wangbatun. Because of various bizarre encounters, I actually shoulder the responsibility of saving the earth.

In the process of saving the earth, I will solve for you one eternal mystery after another, and I will take you to experience one alien space after another!
