Signing In for a Hundred Years to Become the Eternal Supreme Emperor

Night Beichen transmigrates to the Ancient Mainland and becomes the decadent third prince of the Sacred Empire.

Night Beichen originally thought he would just idle away his life, but at this moment an invincible sign-in system arrives.

[Sign in at the main hall of the Sacred Empire, reward: hundredfold cultivation speed.]

[Sign in at the library of the Sacred Empire, reward: heaven-defying divine art.]

[Sign in at the forbidden land of the Sacred Empire, reward: Reincarnation Saber Manual.]

With the attitude of keeping a low profile and developing quietly, Night Beichen silently signs in for a hundred years, and then becomes the number one person on the Ancient Mainland.

PS: This is an invincible novel, invincible from start to finish.
