[The recommended novel: "I've been invincible since the black technology system."] This book was about a young man named Gu Guan. He inherited his family's cell phone factory and accidentally activated the black technology cell phone system. From then on, he opened a future world full of black technology. He descended from the sky on the Sky Stick at the press conference, holding the Thor's Hammer in his hand. Lightning shot out in all directions as he made his world-shaking appearance! If you like sci-fi and black technology, this book is definitely not to be missed! I hope you like this fairy's recommendation. Muah ~😗
