Good news: Not dead.
Bad news: The Mongols are attacking the city outside, and the spies inside are digging tunnels, arrows flying over their heads, and people dying at their feet.
Worse news: He inherited the identity of a craftsman's son, who was so poor that he didn't even have a decent hammer.
So he took a stupid blacksmith, a former killer who used poison, a stingy foreman, a chatty businessman, an accountant who went crazy calculating accounts, and an orphan with a slingshot to form the "Brick Moving Alliance".
Main business: repairing city walls, repairing cracks, digging tunnels, preparing gunpowder, improving farm tools, repairing stoves for widows, and bandaging wounded soldiers.
Side jobs: being chased by the Ghost King's Mansion, being shot by the Mongols, being tested by Jia Sidao, and being suspected by Lu Wende.
