Go Back to 2000 and Create the Only Great Power!

You said you wanted to build fishing boats, but your fishing boats chased warships. You said you want to build an airplane, but what the hell is a space carrier? Also, you clearly said you were researching body armor, but why did the entire Army equip themselves with mechas and carry tanks on the battlefield? Li Xingchen: "Leader, you asked me what field I am good at?" "Emm, I can handle warships, aircraft carriers, nuclear submarines, combat transport bombers, tanks and mecha infantry fighting vehicles." America: I can't play anymore, I surrender. From now on, Daxia will be the eldest brother, my biological brother. I will do whatever he says. Little Japanese: Is it too late to recognize my father now? Western powers: Who says we are great powers? Daxia is the only great power!
