Walking by the Abyss on Thin Ice - Chapter 23: Lack of knowledge

The Soaring Dragon Continent is a world of summons, you can only become strong if you become a summoner! Yue Yang, an average high school boy, was suddenly transported into this world. When he woke up, he was greeted with a lot of worried faces and found out that he had assumed another person’s identity. Turns out he’s the good-for-nothing third son of the Yue Family, who had just recently drowned himself because of a failed engagement. Unlike the third son of the Yue Family who was useless in summoning, Yue Yang succeeded in making a contract with a summoning grimoire on his first try, even when the other guy failed for the past fifteen years. Others would have a headache making contracts with beasts afterwards, but countless beasts tried to gain favour with Yue Yang instead, acting like a good kid before him.

Nan Xun encountered a mythical beast that could take her to different worlds. She helped the mythical beast collect merit points. After collecting enough, she can go back and change the outcome of her death.

But now, now she regrets, regrets till her insides are turning green. Your mother, those merit points are collected from the scum villain with a blackening value of 100 and an evil value of 100 ah! She only wanted to purify the souls of those scummy bosses. Fu** she didn’t want them to fall in love with her ah ah ah!

Pervert number 1 eats people! Pervert number 2 is an evil ghost! Pervert number 3….

After Nan Xun realized they were all the same person, she closed her eyes and pretended to be dead.

The evil, charming, crazy Boss-sama gave her an evil smile: “Baby, weren’t you going to purify my soul? Come here.”

Nan Xun: “The evil we bring on ourselves are the hardest to bear, I really want to die, ah, what to do!”
