I Handed Over a Demon Core from the Start, and the Nation Bombarded the Demon King

[Cangyuan World firepower coverage + national fortunes backing the nation + the state machine on cheat mode + an irrational fear of insufficient firepower]

When others transmigrate to the Cangyuan Realm, their first thought is to find a master and cultivate as a god or demon. Lu Chen is different. When he sees a demon king attacking a city, his first thoughts are to find cover, calculate workplace injury compensation, and call for help from his country. If you can gang up on someone, why fight one-on-one? If you can build defenses, why throw your life away in a blaze of passion?

After an old necklace connects him to the Dragon Nation, Lu Chen becomes the only link between the two worlds. He collects samples, takes photos, and sends coordinates; the nation handles modeling, simulations, and process improvements. Whenever danger strikes, his first question is always: “Are our survival odds at least eighty percent this time?”

When powerful clans demand that he hand over his secret method for harnessing baleful energy, he turns around and publishes a simplified qi-guiding method. The demon race thinks a human city will fall at the first charge, so he turns a blacksmith’s shop into an arms factory and has the people of the border city line up to collect rune-engraved firearms. The moment the demon king appears, a drone marks its weak point.

While everyone else waits for him to attain enlightenment and break through, Lu Chen pulls out his second firepower coverage plan. “Sorry, I never fight battles unless I know I can win.”
