Strongest Survival by Otome Game’s Heroine (LN) - Chapter Volume 1 6: Forest Survival

A legendary powerhouse of his generation, tired of the bustle of the peak, returned to the ordinary city and started a new life as an ordinary teacher. He wrote the legend in the city.

Magnificent mountains and rivers, the rising powerful ones. Some ancient martial art masters stood at the peak, becoming legendary. Some financial crocodiles rose up in the minuscule places, laughing arrogantly.

However, watching the school beauties was better than fighting and killing; educating was better than fighting for fame.

Cassian Ven Dyke, the bastard son of a powerful ducal family, grew up in the slums of Veldora under the care of his father figure, sword master Russel. When Russel passed away, Cassian was left with only a silver necklace as his inheritance. After putting it on, Cassian was attacked by three psychotic thugs who tortured him in an attempt to steal the necklace. Refusing to give in, Cassian was ultimately stabbed through the heart with the very same necklace. Instead of dying, he mysteriously vanished as the necklace lodged itself in his heart. Just before disappearing, he heard an eerie message echo in his mind:[True mana detected. Origin: Human...][Human detected. Compatibility with system: Confirmed.]

By the way, I have a cheat!

Star Platinum, The World, Crazy Diamond, Killer Queen, Gold Experience, King Crimson… All for me!

Ding, hello new player, your first Stand has been drawn.

Looking at the ‘Little Tomato’ who was smiling at him, as the only Stand User in the Marvel Universe, Dio was speechless, then lit a cigarette silently, looked up at the ceiling, exhales smoke, it’s just a mystery how life is so harsh!
