Douluo: Why Can't My Hidden Weapon Kill Gods?

This book is also known as "Holding High the Flag of Science from the Frontier", "The Rise of the Good-for-Nothing Prince", "My Farming Life in the Douluo World", "As long as my name is long enough, I will definitely attract readers' interest", "This world aimed at me is hopeless". Dai Yunqing traveled to Douluo Continent and became the eldest prince of the Star Luo Empire. Didn't inherit the White Tiger's martial spirit and soul power? It doesn't matter, anyway, Douluo has hydrogen per capita, so if you want to bulldoze the entire continent, you are not just throwing water. Since Tang San's hidden weapon can kill gods, I will also make a hidden weapon. As a man of science and engineering in the new century, can he be inferior to an ancient craftsman? But when he saw the Dragon Beard Needle he had made one-to-one according to the original work hit the crispy Soul Saint, and the other person scratched his head and looked at him with innocent eyes, Dai Yunqing knew that the world was definitely targeting him. PS: There is only one female protagonist, and the female protagonist appears later.
