I Signed-In For A Billion Dollar Mansion From The Very Beginning - Chapter 477 - Popular Across The Internet,

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…

In a universe where the great experts can reincarnate, Yale Roanmad reincarnated with almost no memories of his past life and didn't know who he was.

Despite the problem with his memories, Yale had obtained a strange legacy from his own past life the Last Wish System.

Yale, who remembered the pain of dying, decided to turn strong to avoid suffering the same pain again. Moreover, he also decided to investigate his own past life to remember who he was.

However, he didn't know that a Mysterious Expert, who knew a lot about him and his past life, was looking at him from the shadows.
