Hero without Blood or Tear

In a world where humanity is overwhelmed by demon lords, a solitary figure emerges as the invincible hero. This man, driven by his own greed, relentlessly hunts down demon lords. He is known as the hero without blood or tears, a testament to his unyielding nature. The narrative unfolds within a fantasy world, potentially a futuristic setting blended with elements of MMORPGs and virtual games. This world features a game ranking system, a level system, and skill assimilation, suggesting a gameplay-like progression. The story incorporates a male protagonist who is both clever and famous, possessing the ability to assimilate skills and employ summoning magic, sword and magic, and strategic planning. He navigates through a world populated by demon lords, dragons, empires, evil religions, and fantasy creatures, including vampires. While curses and necromancy are present, the protagonist's actions are pragmatic, as he eliminates threats to satisfy his personal motives. The pacing is rapid, with little focus on mundane travel or bandit encounters, and the character descriptions are notably vague. A romantic subplot is hinted at.
