Start with a Ruined Temple and Start the Era of Industrial Empire.

He traveled through time and became a beggar, starting with a ruined temple. Others relied on the system and their grandfather, while Zhang An relied on his brain - making coke, brewing spirits, making generators, and making electromagnetic guns. The bandits invaded and were blasted through with one cannon; the aristocratic families were exploited and crushed by technology; the 30,000 Northern Huns army besieged the city. Zhang An stood on the city wall and said only two words - "Fire the cannon." A beggar's start, an industrial empire, starts from a ruined temple.
