Go Crazy! You Call This a Border Blacksmith?

Coinciding with the troubled times, the foreign cavalry went south, and the border was in danger. The imperial court also sent a bunch of guilty officials and their female relatives over, and they were about to starve to death everywhere. In a desperate situation, [God-level military industry system] awakens! Others forge iron to make farm tools, but Fang Tian makes all things with his hands. From fine steel armor to repeating crossbows, there is nothing he can't imagine! From then on, the style of border painting was completely distorted. The eldest princess in trouble who used to be cold and arrogant, and would rather die than give in, now puts down all her body, wanders around the blacksmith's furnace, puts on a maid's uniform with a red face, blows the bellows for Fang Yan, and lets him rest coquettishly, she looks like a docile little maid. Fangtian pretended to be fishing and farming while he was busy working in the military industry. He took care of the border areas and prospered. The warehouses were filled with grain, the iron tools were piled up, and he was surrounded by beauties. He lived a happy life with many children and many blessings. Three years passed in a blink of an eye, and there was civil strife in the Great Xia Palace. Rebels were everywhere. The emperor was hunted down in a panic and fled all the way to the border, just for pleasure. But when he looked up, he was dumbfounded on the spot! The once dilapidated border city wall was actually made of reinforced concrete and was impregnable; a row of red cannons on the top of the city were neatly arranged with a terrifying momentum. They were sacred objects that he had never seen before! What made him collapse even more was that the eldest princess, who he thought had died tragically at the border, was delicately holding a plate of crystal grapes and carefully feeding them to the blind blacksmith who was lying leisurely on the rocking chair. The emperor broke through the defense on the spot, holding his head and wailing: "Is my Daxia dead long ago?! What the hell is this place!" Invincible military industry + sand sculpture daily life + ambiguous Shura field + many children and many blessings
