The Misfit of Demon King Academy (WN) - Chapter 11.1

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?

In a world where magic is forbidden and witches are hunted, Ashlynn Blackwell has hidden her mark of the witch since birth. The night of her wedding she's betrayed and her secret is exposed. Attacked by her husband and his knights, Ashlynn was abandoned and left for dead in the wilderness.Rescued by the vampire lady Nyrielle, Ashlynn is offered a choice: die as a human or embrace her power as a witch. Bound by a mystical blood pact, Ashlynn is plunged into a world of ancient magic, immortal vampires, and deadly political intrigue for the chance to find eternal love.

Revenge is merely a method of passing time for someone like Lee who has lived several lifetimes, but the desire to acquire superhuman, godlike powers becomes an obsession that pushes him beyond limits. It’s a struggle to grow up in the world ruled by masters who bend elements to their will, with little hope of learning their cultivation secrets, but they are still there for taking for those with wit, persistence and the ability to take risks.Join Lee on his adventurous journey where every challenge, setback and achievement brings him closer to divinity!

This crossing is so strange, death crossing, game crossing, etc. are probably barely acceptable, but why can you cross even if the fish tank is broken?

and actually passed through the magic tree in “OVERLORD” that is said to be able to destroy the world?

No! It is sad enough to regenerate into a plant. The protagonist, Ainz Ur Gong, the undead king, has also accepted the adventurer’s guild mission and wants to kill me!

I want to change my destiny! Live! I want to-surrender!

Ainz: Since he has accepted the job commission from the Adventurer’s Guild, deliberate failure is detrimental to the prestige of Ainz Ul Christine (the “surrender” button has been deducted)

actually died as soon as he crossed, but there is still a chance to return~ from the beginning of the magic tree to this world.

I must change my destiny this time! Live!
