MTL - This Game is Not Easy - Chapter 194 had an impression

This is a story of a man named Kim Sae-Jin, who one day, inexplicably wakes up as a Monster. Follow him and his perilous journey to get his life back as a Human, all the while growing even more versatile as a Monster in the process. This should be… complicated, somewhat.

In each world, there would be the ultimate blackened female lead called Lin Xia, and each of them would’ve drowned in the light of their first love, aka the moonlight. Unsurprisingly, all of these moonlights were beautiful, attracting the love and adoration of Lin Xia, but in each and every world, the moonlight would eventually leave in the end, ultimately causing the blackening of Lin Xia’s fragile heart.

Years later, when the blackened Lin Xia finally fell for another woman, the special memories of the moonlight which was buried deep within her blackened heart began to fade, replaced by the light of the true soulmate.

And when the memories of the moonlight faded to almost nothing, the moonlight returned abruptly, only to be rejected by the moved-on Lin Xia. Filled with a crazed sense of jealousy, the moonlight began to destroy the new couples’ lives, only to be hated entirely and finally, crushed cruelly by the angered female lead.

And this is where the story begins, as a world-hopper, Ye SangSang would complete her missions in these worlds.

In the year 3000, humanity was forced to leave the earth when a sudden mutation caused more than 70% of the planet's population to mutate either into zombies, werewolves or vampires. The humans put up a fight but didn't have a chance against the united front of the monsters and they were forced to leave. At least those who were rich and lucky enough to leave.

A century later, the chaos on earth had calmed down but the humans who were left behind were treated like slaves and were forced to join one of the three factions: The Undead, The Cold Ones or The Lycans when they turned 16.

It was a similar story for Ashton, who was one week away from being turned into one of the monsters as it was his 16th birthday. He decided to run away from his fate and join the secret resistance to battle against the monsters.

However, his plans came to a standstill, when a series of misfortunes leads him to be bitten by a Zombie, a Vampire and a werewolf before either of his powers could manifest.

He ended up receiving all of their powers, but at the cost of his humanity. Yet, he wasn't willing to let his humanity die. No matter the cost.

Will he be able to live his life, or was it already too late? Which faction will he join? Will he be able to find the secret behind the mutation?

There were too many questions, and only one way to find the answers: follow Ashton's journey as he fights back to retain his humanity.
