The National Goddess Reborn - Chapter 263 - Treat her Himself (2)  

Following a brutal and tortured death, a former assassin, known only by his codename Kuro, is given the opportunity to reincarnate in another world, a world with magic and monsters. Armed with an unrivaled healing factor and an inhumane pain threshold, Kuro opts to go for a reckless direct approach in this world instead of a stealthy and cautious one, and as a result, slowly gains attention bit by bit.

Having previously been a loner in his old life, he interacts and befriends people for the first time in his existence, however, his blunt nature also sees him making just as many enemies, both big and small. By combining his old assassin skills with the magic powers of this world, along with his high resistance to pain and rapid regeneration, he doesn't take long to establish himself as a formidable force in this world.

Initially, Kuro only faces minor threats, like weaker monsters and bandits. But before too long, the threats slowly but surely become more and more severe…from Zombies to a bloodthirsty empire to Vampires and Demons, and even divine beings…however, as the enemies he faces grow stronger, so does Kuro, gaining rare powers that have never or rarely ever been seen in this world…

My past life: Ordinary. Mediocre.

I was proposed to by the Final Boss.

She was a medical genius from the Noah Medical Academy as well as a drug producing specialist. After sleeping for three days, she had returned to the ancient era and become the loyal marquis palace’s ignorant and silly young miss.

He was the supreme king of the Jia Luo Kingdom, with prestige around the whole world. With an ice cold face and a ice cold manner, he was entangled by her strong and overbearing manner, vowing to never let go.

Accidentally falling on him, he said, “This king will never suffer a loss.” Never suffering a loss, so he kissed her back.

Accidentally hitting his face, he said, “This king will never fight with a woman, I only nip women.”

Five fingerprints. Not only has he nipped her five times, he still collects interest.
