Chemistry Lord: I Am Climbing the Technology Tree in Another World

Traveling through another world, chemistry professor Lin En became the thirteen-year-old master of the border city. The rich and powerful at home despised him at a young age, orcs slaughtered the city and cannibalized people outside, and the corrupt principality even regarded him as an abandoned son. Others relied on the system to start the game, but he relied on the periodic table of elements. Starting from a grain of sugar and a bottle of spirits, you will become rich with glass and forge a city with steel. While others were still charging with cavalry, improved artillery had been set up on his city wall. When the imperial nobles laughed at his humble origin, his envoys had used muskets and treaties to open the doors of the elves and dwarves.
