On Gu Qingniao’s twenty-sixth birthday, he received an invitation to the Gate of Otherworld. Written on it were his name and a location he had never heard of.He casually tossed it away. That night, one second he was still at home, and the next he had arrived in another world.The invitation appeared in his hand once again.…Yinwu Village, which lived by sacrificial folk customs; the sanctuary church cursed by the blood plague; the ancient merfolk tribe that had vanished for a thousand years; the bottom of the abyss where monsters ran rampant… Every world had its own bizarre and ever-changing rules.If you violated the rules and lost your life inside the Gate of Otherworld, you would also die in the real world.After going through life and death again and again, inside the Gate of Otherworld he casually saved a young man who was being sacrificed.From then on… he could never shake him off.
