Warrior’s Promise - Chapter 3319 - : The massacre begins

Nameless Traveler, “If you could bring the martial arts, Inner Strength, Daoist skills, Divine Skills, and other abilities you've learned in the game into reality, would you play such a game?”Gamer, “Of course, I would play. Is there really such a great thing?”Nameless Traveler, “Then, if you were to die in the game, and you would also die in reality, would you still play?”Gamer, “Let me think about it—um, I think I would play, as long as I'm careful to avoid provoking higher-level monsters.”Nameless Traveler, “What if the game was so difficult that a Little Monster at the entrance of a village could easily chop you down, would you still play?”Gamer, “……”

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?

“No matter what I would do, my actions would inevitably change the story. I knew this already.... But what do you mean that I changed the plot even before reincarnating in the novel!? ”

...

Should I follow the plot of the novel? Or should I do as I wish? Maybe I should follow the plot while making changes favorable to me?

These would be the first questions of those who reincarnate inside a novel. However, due to a certain event, Sol didn't have that luxury. He had already influenced the plot.

The change he created wasn’t small either. If nothing was done, the novel would head for a 100% certain bad end: Destruction of the multiverse.

Luckily for Sol, the plot of the novel had yet to begin. It would take a few months before everything starts in earnest and all the dimensions combine, bringing along the dying worlds and their catastrophes for the Great Merge.

“Yes! I will enjoy my life to the fullest!”

Calamities? Future Catastrophes? Inevitable Destruction?

Sol doesn't care for those things. He has a single aim, to live a life that would make even the Gods jealous!

Be it the hero who brings hope, the villain who crushes the protagonist, or the enigma who controls everything while staying in the background. Sol will switch to any role that benefits him.

But will everything go as he has planned? The longer Sol lives in this new world, the greater mysteries he comes to face. To start with, his new identity itself is….

The world was hit by an abnormal narcolepsy, and there was a mass coma. Lee-joonhyuk was transferred to a dimensional battle field as he fell into an abnormal narcoleptic sleep. This is the story of him as he starts as a minion.
