Zhe Tian: I Signed into the Emperor's Scripture at the Beginning and I Am Invincible!

Traveling through the world of "Shading the Sky", I became Ye Fan's classmate, but on the eve of setting off to pull the coffin in Kowloon, I awakened the [God-level Sign-in System]! Sign in at the beginning of Taishan and be rewarded with "The Sutra of No Beginning"! Come to Beidou, sign in and be rewarded with the Ancient Holy Body! Know the plot well and seize the opportunity! Ye Fan is still practicing hard? I'm ready to preach! The inheritance of ruthless people? Mine! The elixir of immortality? Mine! In this life, I will defeat all enemies, make up for all regrets, and reach the top with an invincible attitude!
