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.

Jiang Yun died in his original world, and his spirit traveled to a cultivation world as the Holy Son of the Sacred Land of Mist. However, his new body was severely injured from being attacked by demonic cultivators and having his Sacred Bones stolen.As he was in despair, a voice from a System, known as the Villain System, sounded. Initially, he was shocked because of his experiences, which seemed like the destiny of a protagonist. However, when he discovered that his junior disciple was the true Son of Destiny and had stolen his Sacred Bones, hiding them, and was a spy for the Demonic Sect, Jiang Yun realized he was being framed. The junior disciple created false accusations against him, causing other disciples to dislike and reject him, including senior and junior disciples who shared the same master.Without hesitation, Jiang Yun decided to become the Villain. He planned for survival, gathered resources, amassed forces, and acquired subordinates. Eventually, his master decided to remove him from his position as Holy Son. He then chose to leave the Sacred Land. When he encountered an Emperor Spirit, he learned that the world was about to undergo a dramatic change in the near future. Thus, he established a Sacred Land for those who were despised and abandoned by heaven, or for those who shared his ideals.

Lin Mu was pushed down the cliff, but he did not die and arrived to a magical world instead.

A huge python with wings and can fly, alright, just think it as the legendary Mayan Snake God;

A gigantic centipede that can fly in the sky, alright, he kinda seen it before in ‘Journey to the West’;

A mighty big wolf with a body as humongous as an elephant, en, just think it as a mutant;

….

Although the animals in front of him were a little strange, they are still animals but why did all of you suddenly turned into humans? Coming across wild beasts, Lin Mu still can accept it, but coming across ‘*yaojins’, Lin Mu became . . . . . . excited instead. What? You guys are the infamous drifter beastmen? I don’t know anything about that. You guys did a lot of heinous crimes? I don’t see that either.

And so, Lin Mu began a hard but satisfying life of building a home in a another world.

*Yaojin/妖精 doesn’t have a proper English equivalent word. The nearest meaning would be supernatural being or Yokai (Japanese).
