MTL - Demon Slayer: The Beginning of the Game Opens the Way of Reward for Diligence - Chapter 84

The world that nurtured the civilization which reached the pinnacle of magic was on the verge of destruction.
The last survivor transmigrated to the past, when the magic civilization started growing, as countless mages were still fumbling their ways through the thorny paths of magic knowledge.
He, who came from the end of the magic era, aim to reach the pinnacle of magic.

As soon as Li Ye opened his eyes, he saw two three-meter-tall giants fighting each other.

“What sin did I do, I’m going to die just after transmigrating!!”

“Ding, feel that the host is in danger, activate the system, and reward the novice with a big gift package – 12 spell powers”

Since then, Marvel has added a superman who can fly, whose eyes can emit lasers, and who can…

“Hulk, from now on, I will be the strongest on Earth!”

“Thor, I lifted your hammer!”

“Ultra, it’s time to go back to the furnace and rebuild!”

“Hella, just because I beat you, doesn’t mean I want to marry you!”

“Purple Sweet Potato Essence, don’t run away! Don’t you snap your fingers?”

“Gwen, Wanda…we are all family”
