I Just Sell Steel Pipes, How Can I Become an Arms Dealer?

Traveling through the parallel world, Lin Fan inherited a company on the verge of bankruptcy and started to revive it from the steel pipe business. Unexpectedly, he was reported by his competitors and surrounded by the army. "You are the one who provides arms to the Middle East?" Lin Fan: "That's unfair, we are all serious steel pipes, used for laying pipelines, for civilian use..." "Then what are all these large drones used for?" Lin Fan: "You said this, this is an order from Huifeng Express, a delivery courier." "And how come the paint you produce can protect against radar and bullets?" Lin Fan: "I don't know either. Coincidences are all coincidences." "Coincidence? Then how to explain this unmanned ship and laser weapon?" As the investigation deepens, various unheard-of high technologies surface. Controllable nuclear fusion, space-based weapons, super mechas, and even starships... The military was completely dumbfounded: "What kind of private enterprise is this? It's obviously a future military factory, right?" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
