On the night when the city of Guangning was destroyed, science and engineering man Luo Tianlong opened his eyes to see the sky filled with blood and fire and the defeated army. He has no system, no golden fingers, only geometry, gunpowder proportions and bastion drawings in his head. But when he finally erected the first five-pointed star-shaped low brick building in western Liaoning, the world quietly showed its fangs to him: those Houjin Beile who used soldiers like a god, those Japanese swordsmen who were well-established in their advance and retreat, and those eunuch Donglin who turned the court upside down - among them, there were visitors like him hidden. However, what they want is Daming's bones.
A top-notch book, it should be by an old author!
