Alchemist of the Last Light
Rosen, a physics whiz, is unexpectedly transported to a dark, otherworldly realm strikingly similar to the game *The Hunter*, becoming the noble young man Rosen. This world is teeming with monsters and fraught with danger, and upon waking, he finds himself in a manor ravaged by the high-ranking vampire Viken, his parents dead, and himself facing imminent death.
Using his knowledge of vampires from the game and his innate "alchemy talent tree," Rosen calmly uses his alchemical knowledge to devise a poisonous scheme, causing Viken to be poisoned by drinking his blood. At the critical moment, a young female hunter, Annie, arrives to his rescue. Though no match for Viken, she creates a chance for Rosen to survive. The two escape together, and Rosen, combining scientific thinking with alchemy, uses nitroglycerin to create a trap, ultimately killing Viken in a cave.
After escaping the vampire's pursuit, Rosen abandons his inheritance and decides to travel with Annie to Holdenburg in the north to remove the blood seal magic binding him. Along the way, they witness the suffering of ordinary people and encounter Mary, a peasant woman afflicted with a strange festering sore, and her daughter Alice. Rosen recognizes the symptoms as resembling syphilis and resolves to cure it. Meanwhile, he senses the village's outbreak might be linked to Dias, a resident mage conducting research, and encounters his magical attack in the wild. Leveraging his profound understanding of chemistry and skillful alchemical manipulation, Rosen defeats his opponent in an invisible battle.
The two secretly bring Mary and her daughter to the town of Sunderland, planning to develop penicillin for treatment. Rosen realizes that in this dark and ignorant world, the combination of alchemy and science can unleash immense power. He vows not only to save lives before him but also to be the first to ignite the flame of civilization, changing the world with the light of science. However, the lurking mage, the mysterious "Blood Rose" organization, and the enigma of the "Apocalyptic Prophecy" still await him ahead.
