Signing in Emperor Wu's City for a Hundred Years, You Will Be Invincible When You Are Born

Chen Yin traveled to another world, thinking that he would live an ordinary life, enter Wu Emperor City to activate the sign-in system, sign in anywhere, and receive various rewards. Sign in at the back hill of Emperor Wu City and get [Collapse Mountain Fist]. Sign in at the forbidden area in the back mountain and get [Wood Element]. Sign in at the Martial Emperor Hall and obtain [Supreme Fighting Will]. Taking advantage of the fact that he was not invincible, Chen Yingou secretly signed in the back mountain for a hundred years. A hundred years later, when the alien wall was broken, an army of millions of powerful aliens pressed into the realm, and countless people in the world were about to face a massacre, Chen Yin was born!
