It was a heaven-sent opportunity: his overpowered space awakened, and he packed up every bit of cutting-edge technology and every weapons blueprint he could get his hands on! On top of that, his comprehension was astonishing: he could understand any technology at a glance and master it in no time! He returned home to serve his country, whose industries were crying out for support. Jiang Chen said, “That's no problem!” From basic materials to advanced weapons, from industrial machine tools to the crown jewels of a great power, one groundbreaking technology after another burst onto the scene, shocking the world! Technical barriers and international sanctions? Against overwhelming strength, they're all paper tigers! He moved into a four-sided courtyard, hoping to quietly focus on his work. But troublemakers kept popping up to make his life difficult. They dared look down on him? They dared try to trip him up behind his back? Then he'd settle old and new scores alike! Whoever needed a beating would get one, and whoever needed dealing with would be dealt with, until the neighbors understood who was truly not to be messed with in the courtyard! He'll empty enemy storerooms with his space and light up the technology tree with his comprehension! He'll marry Lou Xiao'e, punish petty troublemakers in the courtyard, and make the nation proud across the globe! No self-righteous saint, no needless humiliation, just nonstop thrills from beginning to end! The protagonist is both clever and courageous, repaying every grudge and every kindness! With cutting-edge technology in his hands and courtyard troublemakers under his heel, this is my era to rule!
