Back from Guanjiangkou, I Go on a Rampage in the Gaokao Instance

[Infinite-Flow Horror Instances + Immortal Cultivator from the Start + Campus Setting]

Lu Chen studied under the Manifest Sage Lord Erlang at Guanjiangkou for ten years. When he returned, the world's original timeline had changed.

Horror instances descended, and every eighteen-year-old had to face their trials upon graduating high school.

Only those who passed would become Calamity Challengers and qualify to enter university for further study.

Those who failed could only become cattle and horses, serving the Calamity Challengers.

After Lu Chen returned, his strength, far beyond that of ordinary people, caused the difficulty of the instances to skyrocket.

People could die even in the trial-stage instances!

When Lu Chen came back to take his graduation exam, he turned the whole thing into a fight to the death for his classmates!
