MTL - In This Hogwarts Without a Savior - Chapter 3 lily potter

Rainer, an amateur arcanist and college student, sought to create a new spell far surpassing the magic of the few he inherited from his grandfather. Yet the interference of an unknown event during the casting of his spell led him to be thrown through space and time.

A world where the [Demon King] was defeated by a [Hero] that came from another world. People carelessly forgot about their fear of the [Demon King] and of monsters, living in peace.

In a forgotten and run-down cave in the mountains, a new monster that should not have been born was given birth.

The monster’s name was the [Black Ooze]. It was nothing exceptional other than its black color, an ordinary slime.

However, this slime had the special characteristic of being able to take the abilities of the living things it swallowed. It preyed on an insect that had paralytic poison, as well as other animals. Following that, it attacked a human, obtaining his knowledge and [Desire].

Before long, the monster established its target as the female mage that came to explore the cave.

This world still wasn’t aware.

The entire Yunzhou knew that the Ye Family had a new step-child in the house: Ning Li, a low-born and barely literate. However, when she looked at her 17 years old self in the mirror after coming back to life, she grinned.At 17, her step-siblings had yet destroyed her looks and stolen her glory—she still had everything with her. Since she was given an opportunity to start over, she ought to take revenge on everyone who had wronged her before. It would be interesting.After Ning Li was chased out of the Ye Family, she was cherished by the most popular solo singer in the entertainment industry, protected by the top international racer, courted by the heir to a multimillion corporation, and loved by her billionaire grandfather who wanted her to inherit the family business.Even Second Master Lu said to her, “Hold up you little brat, I think you should come home with me.”Rumor had it that Second Master Lu was handsome and beyond any girl’s reach until that one fateful day, when someone saw a drawing of a cool and proud young boy with bangs covering his eyes fall out from Second Master Lu’s book.The news spread like wildfire overnight, and on the next day, Second Master Lu was questioned. Ning Li coincidentally passed by, and upon considering her relationship with him in her past life, she stepped in and shut down the busybodies.Lu Huaiyu stared at the girl before him as he subtly put away the love letter in his hands and said with a smile, “I shall repay you with my body for saving my life.”A long while later, Ning Li saw herself in that particular drawing and she was silenced. She knew it was all a huge mistake.
