I Rub Nuclear Bombs with My Hands in the Fairy World

[Technology Cultivation + Time Travel + Cool Writing + Domination Style + Farming + Breeding] I am a man in science and engineering who has been tortured by work. An accident at work actually made me travel to a fantasy world. However, in this life, I still have a hard life. I was taken to the fairy world to become a training partner for the disciples of the fairy world. Now that my life is at this point, I can only give it a try here.
