The Symbiosis Era: The Pact of Tai Sui

[Cthulhu supernatural powers + wish-fulfillment System + no female lead + symbiote + apocalypse + ruthless and decisive]

This is a symbiote novel.

Lin Ye is a high school senior who hates school and spends all day wishing the apocalypse would come so he wouldn't have to go anymore.

But who could have guessed the System would suddenly arrive, not to give him endless wealth or immortality, but to make him face all kinds of terrifying instances in real life?

“School-averse student Lin Ye detected. Your thrilling apocalypse life is about to begin. The first instance will open in five seconds. Prepare yourself now. You are about to face: the Cthulhu evil god's juvenile form, Heart-Eating Tai Sui.”

But that's not all. Lin Ye will next have to face:

Juvenile evil god cancer cells, fungal infections, mutated parasites, an Old Ones' smallpox virus, the Cthulhu Black Death, Cthulhu malaria, Ebola hemorrhagic fever... The System will give these entities rules for killing. Host, survive and save all of humanity.

Their horror is beyond imagining. The world begins to collapse, and humanity is driven back at every turn. In just a few short years, human civilization is reduced to a handful of base cities, barely clinging to survival.

Watch as the protagonist becomes the one and only Symbiote God in the apocalypse, leading humanity in its counterattack and rebuilding human civilization.
