Calamity-Class Files, Codename: Ghost Messenger!

[Supernatural + urban + invincible protagonist + no female lead + dark tone] The protagonist’s abilities: suppress and devour! He is a terrifying entity no ghost hunter wants to face, and the greatest natural enemy of every evil spirit... He can suppress evil spirits without fail and devour them to evolve. Just hearing about these two abilities is enough to make even the usually arrogant ghost hunters break out in goosebumps... One day, a terrifying evil spirit officially classified as S-rank appears in Longguo’s Shancheng. The Centipede with a Ghost Face once destroyed two small nations, and now its vast domain of ghosts instantly engulfs the entire city. The Longguo authorities immediately send a team of elite ghost hunters to capture it, but they lose contact after entering Shancheng. Not one of them survives... When the news breaks, nations everywhere are in an uproar. Everyone is gripped by panic and despair, and the residents trapped inside Shancheng’s ghost domain are on the verge of collapse. Then Li Yuchen enters Shancheng, his face blue and fanged, standing over two meters tall. Wherever he goes, blood rains down and black clouds fill the sky... The protagonist is neither wholly good nor wholly evil, and does whatever he pleases. Readers are advised to proceed with caution!
