Bloodline System: I Created New Path for Humanity

Cole Saint had everything on Earth. Wealth, genius, and the world's most advanced AI. Then he died. When he opens his eyes again, he's trapped inside the body of a disgraced noble in a world ruled by magic, monsters, and bloodlines. Worse, the original owner had just gambled his life on a forbidden experiment, fusing his human blood with that of an abyssal creature. Now golden veins are spreading through his body, an alien bloodline is trying to devour his mind, assassins lurk within his own family, and death is only moments away. Fortunately, one thing crossed worlds with him. Saint AI. With an artificial intelligence capable of analyzing magic, optimizing cultivation techniques, and uncovering hidden secrets, Cole must race against time to complete a path that no one has ever succeeded in walking before. The Path of Bloodline Fusion. In a world where humanity struggles against monsters, gods, and the endless Abyss, a new legend is about to rise. If the bloodline doesn't kill him first. — Description from novelcodex.org
