Let You Expose the Obsolete Weapons, This Will Scare Yingjiang to Tears

——"I, Zang Dian, was smashed by the emperor's figure in my previous life and traveled through time. In this life, I am forced by the system to become the savior of the universe. Selling the company, dismantling the microwave oven, and welding the laser gun, just to get a piece of "Stardust Alloy". As a result, my nephew stole a gun to go to school and knocked out eight Type 99 tanks with one shot. The whole school was put on lockdown and the whole country was under martial law. It was a hot search around the world! Eagle Country: Hand over technology! Me: Damn it, I even have the nuclear battery in my pocket. Now, the state has given me a building, an unlimited budget, and the right to die at will. Goal? Kick humanity into the interstellar age! ——Friendly reminder: This book is also known as "I started with a laser cannon, and the country told me not to go out" and "Everyone watched me build a Gundam, and they didn't even let me eat."
