In the Bog forest, dangers were in every corner. During the nighttime, the thick white mist blinded the eyes and the chilling air froze you to the bones. Once morning arrived, thousands of ferocious mutated animals as big as the hills roamed for prey.

Among them lived the weakest species on the Meer Continent, the Monster Species. They only survived with their tough bodies in the midst of a world ruled by magic power.

To the mage, they were simply pests that were easy to be exterminated.

To avoid the eyes of the mana rulers, they had to hide in secluded places; in the caves shrouded by shadows or in the dark underground where filth was brimming. But, continuing to hide was not a solution.

When warbeasts sharpened their claws, elves polished their weapons, humans feasted on their greed, and demons searched for prey with their thirst, an orc named Moku was born.

Moku was a world MMA champion who transmigrated into the body of an orc in the magical world. He had always dreamed of possessing superpowers; being able to jump beyond the clouds, shattering the mountains in one hit and running faster than sound.

Moku dreamed of having these powers. He used rituals, magical lore, and all the things that were considered myths and fairy tales in his home world to make him and his tribe stronger.

A promise was deeply engraved by him. One day, he would bring the war to those who underestimated them.

Youyou is a mother’s precious daughter. The word she often talks about is: “My mother said…” Therefore, many people laughed at her for not being weaned, but Xu Youyou didn’t care, she still went her own way, determined to be the best mother’s baby girl.
In high school, Xu Youyou was pressed by the domineering school grass against the wall to confess. Xu Youyou frowned and refused: “No, my mother said that the most important thing for students is to study! Otherwise, they will become the scum of society in the future!” Someone who has a single-digit score and hates studying: “….”
In college, a rich and handsome president He wanted to use favorable conditions to help Xu Youyou, but got a contemptuous look from Xu Youyou: “My mother said, there is no such thing as getting something for nothing, if there is, there must be a conspiracy!” The president who wanted to find white moonlight substitute: “….”
*5874 is a system whose mission is to change the miserable fate of the abused heroine Xu Youyou and make her happy. But, look at the little beany who is only three years old in front of her, and look at the terrible environment of the orphanage. The system decides to tell a lie “Youyou don’t be afraid, I’m your mother.”
After fifteen years of conscientious teaching, the system fell into a deep sleep due to a lack of energy. When it woke up again and found Xu Youyou living in a beautiful villa with countless jewels and beautiful clothes. The system was heartbroken: “Baby, why are you still …” Xu Youyou is excited: “Mom! You finally woke up! You were right! The best money in the world is money earned from loving a brainy man! System: “… Did I say that?”
