MTL - Evolved From Polluting the World - Chapter 7 boundary point

Once upon a time, a hero had been summoned to a different world in order to defeat the demon king. After the war stretching 3 years ended the commendable hero slew the demon king. And he was forcibly deported back to earth after being dismissed.

Such bullshit!

Elves in addition to beast race, dwarfs and demon race. Even though I wanted to make a harem in the different world I saved! My dream will not come true on earth, where there is no magic at all. Thus, the hero returns on his own. Without the blunder of being extradited to earth this time, he will build a harem of his own in a different world.

My name is Qin Jue. At only 16 years of age, I'm already the youngest person to ever become an uncle-grandmaster in the Xuanyi Mountain Sect.Also, I'm the strongest being in this entire world!But unlike other transmigrators, I want nothing to do with the outside world and wish to live a leisurely life on a cliff behind the sect, sipping wine and singing songs.That is until one day, a mysterious girl appears in front of my yard…Join Qin Jue as he deals with sneaky sects and greedy, hostile clans, all while raising a "weed" to sentience and creating heaven-defying spirit-energy "guns".

A heroine character transmigrates and gets busy expanding her golden halo of MC-ness.

A villainess character transmigrates and gets busy changing her cannon-fodder fate.

A side character transmigrates and gets busy stuffing her bottomless stomach. She holds a divine sword in one hand and a little bun in the other. She’s obedient, adorable, incredibly clueless, and frustratingly tightfisted with her words. So what does she do when she spies a cute blonde?

Feng Wu: “Please marry me!”

Ming Xi: …

A hilarious story about an overpowered airhead in a world reminiscent of Coiling Dragon. This particular tale has an interesting mash of tropes.

“You shouldn’t have crossed this line, Elisha, if you didn’t want it to be like this.”

A sturdy arm wrapped around her swaying body. Her head became hazy and an intentional hot sweet sigh was pulled out of her.

‘How the hell did I get myself in this situation—’

Elisha recalled. This never happened before.

‘Yeah, I remember.’

Her future in which she would become the fake concubine to a demonic man from the same family, and would be eaten to death—even down to her bone marrow. A future in which the Cartier ducal family is embroiled in a power struggle and fragmented.

To avoid that future, Elisha threw herself at Lucerne, the archrival of her former life.

Yeah. There was no problem. She knew this man, before and after her regression. She already knew he was the most notorious maniac in the Empire.

20-year-old Elisha owes 30,000 gold coins (about 15 billion won in Korean currency or around 15 million in USD).

After going back in time, in order to avoid a hellish life because of debt, she becomes the most capable illegitimate child in the world and visits Lucerne, the archenemy of her master.

“What do you want from me?”

“Please lend me some money. And… make me your subordinate. I’ll give you all the information I have.”

“Why should I trust you?”

“I’ll give myself up as collateral.”

Lucerne listened to Elisha and watched her quietly.

“Okay. But I decide how to deal with the collateral.”

“…….”

“First of all, marry me.”

“…… huh?”

Elisha didn’t expect it either. That her information transaction would become a marriage contract.
