To become a criminal soldier of the Ming Dynasty, Feng Qingya will be filled into the foundation of the Great Wall at the beginning. The Tatars held the pass, and the supervisors sharpened their knives. Even the cornstarch in their hands was mixed with stones. But he discovered that he could actually understand the Great Wall - not the cold bricks and stones, but a giant war beast that had been sleeping for thousands of years. Build a wall and you'll upgrade, build a city and you'll explode your troops! When others were fighting for power in the court, he had poured concrete into an industrial bastion; when the barbarians invaded, he silently rolled out a row of divine machine cannons. Seeing the Great Wall's defenses fissuring crazily, the emperor asked in a trembling voice where he wanted to build it. Feng Qingya spread out the map of all nations: "Your Majesty, everything illuminated by the sun and moon is bright earth. How far do you think we should build it?"
