Are there any novels that describe modern technology entering the Otherworld?

I recommend the Magic Industrial Empire and Invincible Technology System to you. The main character of the former was a high-level mechanical engineer who had transmigrated to a world dominated by magic. How was he going to realize his value in a world where there was almost no industry? The main character of the latter had a modern technological system and super weapons such as iron turtles and atomic bombs. He could compete with any enemy. They are all novels that are suitable for the fusion of modern technology and the other world. I hope you will like my recommendation. Muah ~
