Key to the Three Realms: Doomsday Restart

Thick fog engulfed the city, locking the day into eternal night. Distorted shadows - countless black humanoid spiders - crawl silently on the remains of the steel forest, weaving a cocoon of doom. When the door to heaven that tore through the sky suddenly opened, a young man fell into the bottomless abyss like a meteor. However, the end of the abyss is not destruction, but the deathly paradise. In this sacred ruins, his desperate call penetrated the barriers of law and accidentally awakened the demon that should have been imprisoned in the deepest part of hell. The world was wailing on the edge of collapse, but the young man who fell into heaven became the only key to the survival of all things.
