Reincarnated in Another World, I Sleep for Hundreds of Years

[Western Fantasy] [Alternate World] [Immortality] [Pseudo-Invincible Growth] [The Goddess Lives in the Brain] While others meditate and practice, Allen just needs to sleep. The longer you sleep, the stronger you wake up. After sleeping for three days for the first time, he awakened his magic power. The second time he slept for three years, the enemies who once pursued him had grown old. A hundred years later, the kingdom was destroyed, the sword master turned into withered bones, and the young dragon of the past had become the dragon king who ruled the sky. Everyone thought that Allen, who woke up from the old era, was some immortal and powerful man who was hiding in the world. Only Allen knew that he was just cursed with eternal sleep and wanted to get home before falling asleep next time. But when the gods revived, the demons invaded, and countless powerful men begged him to take action—— Allen looked at the fireball technique he had just learned and fell into silence.
