Fight, survive, adapt, and rely only on yourself.That is Derek’s creed, and what's gotten him through the System Integration on Earth.Everything changed when the System came. Cute bunnies and beautiful butterflies became savage killing machines. Then the Invaders arrived with a single goal: to obtain ownership of this new habitable planet.War has raged ever since.None of this mattered much to Derek, aside from making living a little more perilous. He mostly kept to himself. He was the weird guy who owned a cabin that occasionally came into town for a drink and light conversation. After System Integration, that didn’t change much—he only got stronger.After years of fighting monsters and Invaders alone, he’s become quite adept at surviving. Who needs others to get in the way or worry about?Until one day, Derek goes against his better judgement. He decides to lend some help on a mission that doesn’t seem too hard… He should have stuck to being alone…

In the distant past, a time of magic and swordplay, there lived Harold, the mightiest lich of all, a master of arcane sciences, and a challenger of gods. After reaching the pinnacle of his power and finding it surprisingly bland, Harold waged a cataclysmic war against the gods, aiming to shatter the very system that confined him.

Then, he took a nap.

An incredibly long nap that ends with a jolt, thanks to an unwitting adventurer who trips into Harold's crypt. Blinking into the torchlight, Harold finds a world he barely recognizes. No more swords and sorcery, but a universe buzzing with cultivation, celestial sects, and far too many pretentious dialogues about the path to godhood.

Harold is no naïve cultivator, he's an ancient lich with a single ambition: to slide back into his uninterrupted eternal slumber. But the cacophony of quarreling sects and smug martial artists seems determined to keep him awake.

Undeterred, the sleep-deprived overlord is ready to confront this brave new world. After all, no aspiring deity, no grandiose sect, and certainly no self-righteous martial artist is going to rob him of his beauty sleep.
