Starting Arsenal: I Am the Overlord in a Different World

Betrayed by his girlfriend and teased by his enemies, Chen Ping accidentally traveled to another world carrying an entire arsenal of future weapons on his back? Then, for Chen Ping, the happy time is about to begin! What kind of martial arts master, what kind of heroic assassin, can you withstand a shot from me? He quickly accumulated his own power in other worlds through the advantages of science and technology, established underground forces, spread intelligence networks, conquered cities and territories, tamed various exotic beasts, and even created a feared Black Flag Army with modern training standards! There's nothing that can't be solved with one shot. If so, then maybe, just use your brain? But slowly, he discovered that this different world was not as simple as he imagined... Orcs, elves, chaos... More mysterious forces are unveiled one by one. Chen Ping secretly made up his mind that when he returns, he will lead the strongest army in the universe and let those who have betrayed him, insulted him, and tortured him know what it means to be cruel! (I promise everyone, the story of the different world will become more exciting as it goes on!)
