Lin Yu, an urban social worker, did not arrive at the hospital after a fatal car accident. Instead, he fell into a strange and twisted alien world - the shadow of a giant creature crawled under the lead-gray sky, the bones and plants rustled on the barren plain, the low-frequency hum of ancient giant beasts came from the ground, and the air was filled with the sweet taste of rust and rotting algae.
The yellow mark that suddenly appeared on his chest was like an open bloody eye, tightly binding him to the terrifying legend of the "Old Dominator". The eerie murmurs of the mysterious cloaked figure, the tentacled monster emerging from the ground, the twisted symbols on the stone surface like living creatures, and the eternal whispers lingering in the mind all indicate a madness and crisis far beyond imagination.
Should he become a sacrifice for Cthulhu's awakening, or should he use the power of the Yellow Seal to escape his fate? Lin Yu was forced to struggle forward in the fog of terror, and step by step uncovered the prophecy of the star's return, the truth about the alien world, and the eternal dark secret behind the yellow seal. When the sleeping evil god is about to awaken, can he maintain his sanity on the edge of madness?
