Crossing Two Worlds, I Became the Queen of the Blood Race

: [Transportation between two worlds + one soul and two bodies + crazy female protagonist (male protagonist) + white-haired red-eyed sister + magical background + high martial arts + extraordinary + ease + decisive killing + not the Holy Mother] Elite programmer Qin Beiqing had just finished a day's work and was returning home with his ancestral martial arts yellow book. He only heard the sound of brakes and the head of a truck approaching. When he opened his eyes again, he found that he had been reborn and returned to the college entrance examination before he was eighteen years old. Just when Qin Beiqing thought he could make up for the regrets before his rebirth and live a prosperous life, he discovered that he would travel to another strange world every night as long as he slept, and become a girl with white hair and red eyes. The Yellow Book of Martial Arts, which was originally impossible to practice successfully, can even be practiced successfully in that world. From then on, in the extraordinary world of demons, humans, elves, giants, the eight major races, alchemy technology, magic potion sequences, and countless terrifying demons, a blood queen appeared who knew martial arts and magical skills and could tear giants apart with her hands. Ten days in the extraordinary world, but in reality it was just one night. The martial arts practiced can not only synchronize with the real world, but also synchronize reality with the knowledge of the extraordinary world. Legendary alchemy + modern technology = alchemical technology. Miraculous potions bring people back to life and gain extraordinary powers, and modern technology enables wholesale. From then on, I am the only one who has my own way in the world, and I am a saint in front of others!
