Western Fantasy: the Evolution of the Blood Demon from Another World

[Western Fantasy + Sword and Magic + Imaginary World View + Weak Group Image + Hegemony] The protagonist Teddy, whose soul traveled to another world and whose identity was the son of a blacksmith, acquired a weak body and earned the title of a good-for-nothing son. I originally thought it was anemia, but who knew it turned out to be a mutation in my bloodline, causing me to become invisible after sucking blood. In this different world, I was definitely a heretic. In such a barren countryside, he could only grow insignificantly. Fortunately, this body has an excellent shooting talent. With this skill, he finally became a mercenary. From cannon fodder newcomers to skilled veterans, they are accustomed to fighting, cruelty on the battlefield, rules of plunder, and all kinds of betrayal. As the blood-sucking nature awakens, one gains strength, status and power through endless killing. What greeted him were plundering tribes, separatist lords, and broken royal power. There is no absolute justice, only survival, loyalty, betrayal, plunder, land and war games. "In troubled times, there is no right or wrong, only the living and the dead." This is what Teddy said in admiration for all living beings.
