I Transmigrated Between Two Worlds and Became the Vampire Queen

[Travel between two worlds + one soul, two bodies + crazy heroine (male lead) + white-haired, red-eyed mature beauty + fantasy setting + high martial arts + supernatural + lighthearted + ruthless killing + not a saint] Elite programmer Qin Beiqing had just finished a day's work and was heading home with his family's treasured yellow martial arts manual when he heard the screech of brakes and saw a truck hurtling toward him. When he opened his eyes again, he had been reborn back to the college entrance exam, before he turned eighteen. Just as Qin Beiqing thought he could make up for the regrets of his previous life and enjoy a wealthy life, he discovered that every night when he fell asleep, he transmigrated to another strange world and became a white-haired, red-eyed girl. The martial arts manual that he had never managed to master could actually be practiced successfully in that world. From then on, a vampire queen who could wield miraculous martial arts and tear giants apart with her bare hands appeared in a supernatural world of monsters, humans, elves, giants, eight major races, alchemy, potion sequences, and countless terrifying monsters. Ten days in the supernatural world amounted to just one night in reality. Not only could the martial arts he practiced carry over to the real world, but knowledge from the supernatural world could also be brought back. Legendary alchemy + modern technology = alchemical technology. Miraculous potions could bring the dead back to life and grant supernatural powers, while modern technology made mass production possible. From then on, I alone wielded supernatural arts in the human world, revealing my divine power before all!
