By Guarding the Tomb, I Became the Best Immortal in the World

What I am guarding is not the tomb, but the eternal heavens! After traveling through time and becoming the most humble tomb-guarding disciple of the Qingyun Sect, Chen Xuan was stepped on by his fellow disciples, even worse than a dog. Just when he thought his life was completely over, the [Tomb Guardian God System] suddenly activated—— The desolate mass grave in the back mountain is actually the burial place of ancient gods and demons! Scan the tomb once to unlock the inheritance of gods and demons; Watching the grave for one night will increase your cultivation by one million; Protect the land and awaken the supernatural power. The genius of the sect who once bullied and humiliated him was casually crushed into dust by him; The once aloof elder sect leader was frightened to death by his sight; The holy places all over the world rush to worship, and the powerful men in the world bow their heads! The world laughs at me for being a humble tombkeeper, but they don't know— What I guard is the Eternal Emperor, and what I cultivate is the number one immortal in the world!
