I'm Invincible After Signing In For 30 Years

The Forbidden Land of Da Cang Kingdom was known as the 'Yin Death Land', and those who entered would die without a doubt. As the crown prince, Ye Chuan was exiled to the forbidden land because of a crime of treason. In despair, he bound himself to the Sign-In System. Sign In at the entrance of the Forbidden Land, received the Spirit Transformation Art! Sign In at the courtyard, received the Collapsing Sword Art! Sign In at the Bed, received the Heart Pill! Ye Chuan originally wanted to sign in quietly, but he did not expect that there would be a conspiracy everywhere. He had no choice but to leave the forbidden area."I only wanted to be invincible in silence, but you forced me to take action!"
