Mechanic of All Realms

Come on, I'm really just a human being. What do I do? Um? Let me think about it, scholar, engineer, scientist... Don't, don't kill me, what I said is true! Parallel universe, different dimensions, or am I dreaming? I don't know, anyway, I traveled through time. When you were in your twenties, you participated in a national key engineering project and held an important position. You thought you were on top of others, but due to an accident, you came to a strange world where gods and demons coexisted, and immortals lived in the world. When survival becomes the first factor, you will unleash 120% of your potential. Cultivation? Sorry, I don't know how. You can cultivate your immortality while I develop my technology.
