A Doomsday World Through the Dual-Passage Gate: Trading for a Lithography Machine from the Start

Chu Qing of Dragon Nation's Ninth Scientific Research Bureau obtains an apocalyptic plane that allows travel between two worlds. He discovers that he can bring high-tech products back to Earth.

Chu Qing: "We need to make our own Dragon Core."

Gaul Chicken Nation: "Dragon Nation has formed its first space strategic force. Please take us along!"

Sakura Nation: "Chu Qing, could you sell us your mecha technology?"

Chu Qing: "The electromagnetic rifle has been developed and is about to enter mass production. Pakistan is exempt..."
