MTL - I Can See Through All Information - Chapter 83 Letter, Shining Armor

While on a school field trip in the Czech Republic, Kang Hyuk happens to stumble into a shop called “Archmage.” To his disbelief, the shop is actually owned by an archmage… from another world! Forced to become the Archmage’s disciple, Kang Hyuk is punted into the Kallian Continent, where might and magic overwhelm and wyverns fly high in the sky…

In this world, people are either sword-wielding knights, magic-wielding mages, or spirit-wielding summoners. There hasn’t been anyone yet who can do all three… until now.

Eira thought there could be nothing worse than being abducted by she-wolf traffickers, abused, tormented, and ultimately sold off to five powerful Alphas as nothing more than a breeder.She was wrong. The worst was yet to come.She was sold to the same five alphas who had ruined her life and were the reason for every torment she had gone through over the past six years.The Alphas were just as stunned to see her, yet they had no choice but to accept her for the sake of their pack’s future. Because pureblood she-wolves were rare, nearly extinct. Only they could bear the offspring of powerful Alphas, and ensure the survival and strength of the next generation.She hated them with every broken piece of her soul. And they hated her in return.The hatred was mutual. So what now?Eira made a silent vow. She will make them feel every brutal torment she had suffered. Every scar, every tear, every cry in the dark, they will taste it all.But the Alphas had plans of their own. They will use her. Breed her. And when she was no longer of use… they will kill her.But what will they do when the mysteries from the past start to uncover and lines of hatred start to fade into something else?Was it too late to regret?

The end of the world is coming, the world has undergone great changes, and everything has changed. Plants, animals, and even insects, as long as there are living things, have mutated.
Become more powerful, and even evolved supernatural abilities, such as chickens and ducks that can fly to the sky, such as cats and dogs that can breathe fire.
But only humans, without any obvious changes, seem to have fallen from the top of the food chain to the bottom of the food chain overnight.
Any creature that can open its mouth to eat can treat humans as food.
But fortunately, this world has not completely killed humans. Gradually, humans discovered that they had the ability to cultivate compatibility with other creatures.
As long as it has a high degree of compatibility with some powerful mutant creatures, it can be used for its own use to achieve the purpose of protecting itself.
Fang He is a person who is very compatible with mutant animals, but it is also because of his ability that he has changed from the strongest to the stupidest.
Fang He, who was reborn, said, “Hmph, this time…”
