After putting a suggestion to add a mercenary in a bad Murim novel he read, Leo would finish a mission with his NPCs before sleeping. Or so he planned. For some reason, he was transported into the said novel as the extra mercenary added by the author. His loyal NPCs, a yandere secretary, a happy-go-lucky assassin, a sexy puppeteer, and two weapon maniac guys start to become sentient. He lead his mercenary band ’Hallowed Insects’ toward an an unprecedented future in a Murim most turbulent era while enjoying his time. Fortunately, they still have their futuristic equipment with them. Tang Clan have a Poison Dagger, they have a Photon Sword. Shaolin Sect has a Qi Blast, they have a Railgun. And of course... “How much are you willing to pay to employ us? By the way, Demon Sect pay us 50,000 Golds to join their side in the upcoming war.” ... he always sided with the highest bidder.

In a world where warriors and mages wield incredible power to battle monsters and conquer dungeons, Leon was just another hopeful teenager awaiting his awakening. At eighteen, he stepped forward to touch the Awakening Orb, dreaming of a legendary class—perhaps a powerful Mage or a fearsome Warrior.But fate had other plans.[You have awakened the F-Rank Class: Necromancer][Your subclass is: Zombie Lord]The world sneered.

With the right combination of magic, strategy, and firepower, his undead army could be unstoppable.Armed with a mana-powered magic gun, Leon fights alongside his growing legion of enhanced zombies, proving that an F-Rank class can become the most terrifying existence in the world.The dungeons will fall.The strong will kneel.And soon… the world will know the name Leon, The Zombie Lord

Natsuki, a third-year at Sakuragaoka High School, who holds unrequited feelings for her childhood friend, Yuu, who’s in the Film Club. However, instead of being honest about her feelings, she makes him be her confession “rehearsal” partner. Unable to say her true feelings, things start to get complicated when Miou and Akari, who are also in the Art Club, get involved! Will she ever be able to confess for real!?

[This is your typical story where there is a System of unknown origin given to mankind, and the existence of Towers, Dungeons, and Constellations, the known or unknown ‘Gods and Demons’ of humanity’s collection of myths.]

— Ding!

[Astronomical Event!]

An event called 'Emergence of Races' struck the human world where the planet Earth was stretched out like dough causing it to become seven times its original diameter.

Various Towers and Dungeons sprouted out of nowhere that caused an earthquake that broke the seismic scale.

Billions of humans died in the process that crumbled human society in an instant.

And just like that, Russell Moon reincarnated in the world of his-considered-failure unpublished novel [The Forgotten Swordsman of Ruined Star], sixteen (16) years before the beginning of the ‘Main Story’ which was set forty (40) years after the Emergence of Races.

And due to that very reason, the existence of 'Untouched and Unknown elements' came back to bite him!

'Why did I write that way?'

Russell Moon lamented.
