I’m Invincible After Signing In For 30 Years

The forbidden area of the Great Blue Kingdom is known as the “land of the dead”, and those who enter are dead and dead.
As the prince, Ye Chuan was exiled to the forbidden area for a crime of collaborating with the enemy and treason, and bound to the sign-in system when he was desperate.
Sign in at the entrance of the forbidden area and get the Spiritual Transformation Art!
Sign in in the yard and get the Great Sword Art!
Sign in at the bottom of the bed and get a pure heart pill!
…
Ye Chuan wanted to sign in silently, but he didn’t expect the conspiracy to spread, and he had to walk out of the forbidden area.
“I just wanted to be invincible silently. You forced me to do it!”
