Death… And Me - Chapter 2472 Follow Roan’s Plan

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout. Will Thomas Harrier be able to live his second life in peace while running an empire and getting it back to its former glory? Or will he succumb into a conspiracy lurking within the country's borders?

“It was an era taken over by a single online game, the “”Second World.””

The “”Second World”” offered a vast amount of classes and skills...

Micheal, our protagonist, reincarnated back into this era and realized he had a few bugged passive skills that would put him as one of the best.

[Passive skill: Damage Reduction: When you receive damage from an enemy, the damage will be reduced accordingly to the reduction percentage. Skill lasts for 10 seconds and takes 10 seconds to cooldown.]

[Passive skill: Damage Reflect: When you receive damage, the damage will be reflected accordingly to the reflection percentage.]

[Passive skill: Damage Multiplier: When you deal damage to an enemy, the damage you dealt will be multiplied.]

[Passive skill: Sword Attack Nullifier: When you attack an enemy with a sword, the enemy will kneel in front of you and catch your blade with their bare hands.]

[Passive skill: Priest: When you suffer from damage, automatically heals yourself.]

[Passive skill…]

[Passive skill…]

.........

After reading through all his passive skills, he suddenly realized how invincible he as.

Even though he didn’t possessed a single active skill, he could still triumph over everyone else with his passive skills.

One day, when the “”Second World”” mysteriously merged with the real world, monsters and divine beings began to invade Earth…

That was when Micheal realized that his passive skills have also given him the power to kill these divine beings…”

The Red Dragon came from the vast wild wastes, coveting all the strength in the world. It once had countless titles: Mountain's Wrathful Flame, Infernal Calamity, Crimson Emperor, Ashen Dragon......The world trembled under the shadow of the giant dragons. He stirred up the craze of the magic industrial revolution; in the empire he established, Wyverns roared, artillery fired in unison, and steel beasts appeared in the sky and on the land, while disasters from another world rampaged everywhere.“Submit, or die.”Cassius spread his wings, blotting out the sun, and gazed down at the trembling humans, elves, and dwarves below, saying thus.......It is a story about a Red Dragon with a player template conquering, ruling, and transforming an alternate world.(Pseudo of DnD, The Fourth Calamity, Red Dragon)

Book I: Lost ThingsTristan Abrascal is a thief, one of many making their living under the perpetual twilight of the greatest city in all of Vesper. Quick wit and a contract with a capricious goddess have always kept him one step ahead, until one night he crosses a line by accident that burns all the bridges he had left. But not all is lost, as his mentor offers a way out of peril that turns out to be more than a simple escape.It is also an opportunity to get even with the infanzones, the nobles he’s lived under all his life, and it so happens that Tristan has a full ledger’s worth of scores to settle with them.Lady Angharad Tredegar has fled halfway across the world, leaving behind a ruin of a life: her family butchered by a ruthless enemy, their estate torched and their nobility revoked. Yet no matter how far she flees the blades of assassins follow, and she finds herself growing desperate for any protection. She has one relative left to call on, her estranged uncle, but she finds that the safety he offers comes at a cost.Angharad has sworn revenge, however, and her honour will allow for no compromise. She will do what she must to survive so that one day bloody vengeance can be visited upon her enemies.The paths of the two take them to the doorstep of the Watch, but for desperate souls like them enrolment is a lost cause. They will have to do it the hard way instead, by surviving the trials on the isle known as the Dominion of Lost Things.Where every year many go, and few return.Book II: Good TreasonsThe trials of the Dominion are over.The four survivors have become students of Scholomance, enrolling together as a cabal, yet even on those infamous grounds they soon learn none are beyond the reach of their pasts.Angharad Tredegar is returned to a semblance of the world she left behind, but finds her honor sorely tested by bargains offered - every bit as tempting as in the stories and even deadlier.Tristan Abrascal needs answers. Mysterious enemies keep trying to abduct him, his classroom does not exist and he’s now had several conversations with dead people. Worst of all, his carrots keep dying.Maryam Khaimov is going mad, which would worry her less if it were happening on schedule. More frightening yet is the possibility that she is not, and there truly is someone else going around wearing her face.Song Ren must forge the others into a functional unit, all the while fending off enemies on all sides: rival cabals, vengeful countrymen and the deluge of implacable foes her companions simply cannot seem to stop attracting.Failure is not an option, for Song must bring back honor to her family’s name whatever the cost: it is the only way to keep their disgrace from literally eating them all alive.And as the four chase shadows in Scholomance, in the distance looms the greater test awaiting them in the Asphodel Rectorate. Asphodel is a faded power, the rotten carcass of what it once was, but under that rot looms darker things - of which monsters might just be the least dangerous.Besides, is treason really such an evil when you have the best of reasons for it?
