I have a few good recommendations for novels about science and technology or alchemy geniuses who are reborn to develop science and technology in another world. The first was "Universal Repair Shop". The main character, Chen Tianze, was reborn and obtained a repair system. Not only could he repair items, but he could also develop black technology and lead a new technological revolution on Earth. Secondly,"Technology Dominance" and "Creation Trading System" were both good science fiction novels. The main characters used their own wisdom and technology to change the structure of the entire world. If you like fantasy elements, you can watch "Black Technology Journey to the Other World". The main character uses black technology to dominate all planes in the other world. I hope you like my recommendation, Mwah ~😗
