Zhou Kun traveled to a post-apocalyptic wasteland, where mobile cities were humanity's last refuge. As supreme ruler of the Wanderer mobile city, Zhou Kun suddenly unlocked [Flesh Technology], allowing the city to fuse and evolve with monster genes. From then on, the cold steel machinery began to surge with flesh, and the city gradually became a living being. Devouring, evolving, and transforming, while other mobile towns struggled with energy depletion, Zhou Kun began dismembering monsters and extracting their genes... From steel cannons, he evolved into [Godzilla's Atomic Breath Cannon], from prosthetic limbs, he evolved into [Venom Symbiote Suit], from powered sails, he evolved into [Fallen Dragon Skywings]... Ultimately, a super-mobile fortress woven from flesh and machinery became the nightmare of all civilizations.

Chu Sheng traveled to a doomsday world.

The monsters were chasing after humans by smelling their scent, and the survivors, led by the sequence ability users, formed a team and lived a life of escape from the monsters.

Chu Sheng awakens the upgrade system, and the supplies on his body are constantly upgraded.

The butcher knife turned into a scarlet butcher full of murderous intent.

The bicycle became the 100-ton king that rushed around.

.......

"You've met a good person by meeting me!" Chu Sheng pulled out the butcher knife and smiled shyly.

"The Doomsday is so dangerous. If you die now, you won't have to worry about dying in the Doomsday later!"

Kaede Tsukasa crossed into the world of Naruto and mastered the secret art of Corpse Escape.

Soon, unsettling rumors began to spread: fallen comrades were seen wandering beneath the moonlight, and patrols of ninjas were ambushed and devoured by the dead themselves.

Whispers echoed across the shinobi world:

"Someone has created a forbidden technique that overturns life and death. Never let that person touch a corpse!"

Yet, Kaede Tsukasa cared little for the world’s fear and misunderstandings. For him, it was never just about the corpses—the living, too, could not escape his grasp.

"The corpse is my eyes, and the art of the dead is my art."

With the Art of Reincarnation, he siphons vitality from zombies to achieve immortality.

With the Art of Mutual Multiplication, he summons legions of the dead to command time–space ninjutsu surpassing even the Flying Thunder God.

In this new age, ninjas must guard not only their ancestral graves—

but their very lives.

[Ding! Fusion successful! Congratulations, host, you have obtained one "Mortal-grade Low-level [Body Tempering Pill]"!]

What? What others see as trash can all be transformed into treasures in my hands?

Then wouldn't this endless mountain of garbage be my supreme treasure trove!

From this point on, bizarre cases frequently occur in the Demon Suppression Prison, once known as hell on earth and infamous for its gloomy, terrifying atmosphere!

Why do the demons and monsters in the prison wail miserably every night?

Why has the corpse demon, capable of transforming into various beauties, donned black stockings and switched careers to become a foot massage therapist?

Why has the eye demon, expert in soul-snatching and illusions, turned into a VR headset?

Why is the fox spirit performing otaku dances?
