Wuhun Age: I Have a Black Technology System

[Low presence system] + [Passionate] + [Double heroines] Chen Feng spent his life and successfully invented a cutting-edge black technology weapon. But for some unknown reason, he did not cross Naihe Bridge and drink Meng Po soup. Instead, he brought all the knowledge and talents from his previous life, as well as his works, to a bizarre fantasy continent. The nano-deformed metal will eventually glow and heat in his hands. Tremble, mortals, technology is the ultimate source of human power! (PS: I changed the skin. If you have read a book with the same theme and the protagonist is also named Chen Feng, don't doubt it, it was also written by me. This book is a reset version of that book.)
