MTL - Turns Out I’m Crazy - Chapter 2 who am I?

Vainqueur Knightsbane is your average dragon: a giant, fire-breathing lizard who loves to take naps on his golden hoard, kidnap princesses for fun, and make the life of adventurers miserable. Vainqueur's only pleasure in life is to watch his treasure get bigger, one coin at a time.

So when a would-be thief turned unwilling minion tells him about "classes," "levels," and "quests," Vainqueur wonders if maybe, just maybe, he should consider a career change.

After all, why bother hunting monsters for free when you can get paid for it?

Murphy has transmigrated to a wizard world where the original body owner is taking the test to become a Knight Servant. Fortunately, he awakens the cultivation system but he doesn't know the first reward from the system is horse-training skills.

Lu Jiangxian died after staying up late one night. Yet, he finds his soul trapped in a fractured, bluish-gray bronze mirror. He falls into a boundless world of immortal cultivation and finds himself in the perilous landscape of Mount Dali. There, a small family from a small village by Meiche River picked the mirror up and is bestowed with the ancient teachings of the immortal ways, heralding the dawn of a splendid new era.

What the hell is this? What the hell happened here?
