MTL - My Sword Intent Can Be Infinitely Improved - Chapter 4 Protest is invalid

James, a brilliant mechanical engineer and passionate history enthusiast, loses his life in a tragic house fire—only to find himself in a mysterious world as the ruler of an island nation. Armed with his modern knowledge and unwavering ambition, James embarks on a bold mission to industrialize his kingdom and build an empire on which the sun never sets.

When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.

- Description from Novelupdates

In another world called Blue Star, the famous son of wealth, Dorian D. Tian, is thrown into a whirl of unfortunate circumstances, resulting in his death.

His parents had a brutal car accident that left them in a coma, and his uncle had quickly taken over the company, seized the company, making sure that he was financially crippled for good.

With that, the famous young master struggled desperately.

And in the end, he gave in to his despair and depression, leaving the sad, lonely world.

The end?

Heh... Think again!

Because in that brief moment, the lifeless corpse suddenly opened its eyes, revealing a deep calm look.

That's right. Another mysterious soul had entered the body.

But if one thought that this story was just about revenge, then sorry... that wasn't even the half of it!

....

The mysterious entity suddenly triggered an exorcist system.

And from then on, both humans and even those from the underworld shuddered in fear and despair at the mysterious soul's cruelty.

[Humans]: “Demon! Demon! You're definitely a demon!”

[Demons]: “Help! Help! The famous demon wants to eat me!”

[Evil Spirits]: “You!... Are you the one who is an evil spirit or us? Why the hell did it seem like you're the demonic one instead?”

[Ghouls]: “You stay away from me! Stay away from me now, you evil entity!”

[Hellhounds]: “Are you sure that you're not the son of hades?”

The system couldn't help looking at its host in doubt.

Its indicators said that its host was indeed mortal. But why did it feel like something was wrong with its host?

Dorian lightly chuckled in amusement.

He would also like to ask the same question.

What exactly was his identity?

Well, this would be the biggest mystery of all.

But Dorian wasn't in a hurry.

Who were his enemies, and who were his allies?

Soon, he would find the truth.

In the meantime, why not play a little?

“Demon! stay back!”

“Oooo~~~... I... I want to go back to the underworld where it's safe.”

“Run for your lives! The demon is here!”
