I recommend the two novels " Magic Industrial Empire " and " Invincible Technology System ". The protagonist of " Magic Industrial Empire ", Xu Yi, was a modern high-level mechanical engineer. He traveled to a world dominated by magic and combined modern technology with magic to realize his career and promote the world's transformation. The protagonist of the Invincible Technology System was also a transmigrator. Through his own technology system, he had powerful technological abilities and launched a series of adventures, battles, and explorations in the foreign world. These two novels both told the story of how modern technology was brought to the other world, affecting the world and changing fate. I hope you like my recommendation.
