“Waking up from sleep, Ye Feng realized that he had transmigrated to a world where the cities had awakened and the whole world lived in symbiotic relations.

Every young person of age would choose a symbiote that was compatible with them.

Some people built a symbiotic relationship with the Ancient Great Dragon of the Origins. After they matured, they could shatter the earth with their dragon breaths.

Some people built a symbiotic relationship with the Twelve Winged Flaming Angel. After they matured, their sacred light shone upon the world.

Some people built a root-level symbiotic relationship with Succubuses. After they matured, they became insanely attractive and charmed the world.

However, Ye Feng’s symbiote was the most unremarkable creature, a Slime?!

Fortunately, he activated the system and awakened the six great sequences at the beginning!

[Perception]: Your ability to sense danger and opportunities is amplified significantly.

[Devour]: You can devour any living being that is smaller than yourself to increase the size of your own body.

[Split]: You can split your body into smaller parts. Each part will retain part of the initial body’s abilities.

[Regenerate]: The recovery capabilities of your various stats are amplified significantly, at the same time your adaptability is increased rapidly as well.

[Mimic]: Your symbiote will evolve at an accelerated pace. Every time it evolves, there is a chance that it can awaken a new ability.

Watch how Ye Feng’s Slime grows to rule the world in the end…

In this world, human are in peril. 72 Obelisks suddenly appeared out of nowhere, infecting the world with Monsters. Amongst this chaos, people look for hope.

A man named Basil Pacifer is the humanity's hope. He is the strongest Mage alive at that point. Sadly, he believes in no man, and he always moves alone.

...

Basil observes the unfolding scene bitterly. He is aware of his impending doom, however he has no grudge. He has lived long enough to achieve things people can only dream about.

Looking back to his past, he realized his life is nothing more than a sad story.

Closing his eyes, he accepted his end — or so he thought.

...

”Look at me! What do you see?“

”Regrets.“

”Don't you want to undo it?“

”Tell me what the offer is.“

Thus, Basil Pacifer returned to the past, being his younger self once again. Of course, he returned back with something.
