Lin Yuan, a 28-year-old engineer, transmigrates into the weakest, skinniest runt in a goblin tribe. The tribe is on the brink of extinction, its members are emaciated, and its enemies are circling. Luckily, he has the complete set of 100,000 Whys in his head.
While others are starting fires with sticks, he's already building a blast furnace to smelt steel. While they hack at each other with stone axes, he's drawing up the trigonometric curves for a horse trap.
When the Church's crusading army arrives at the gates, intent on trampling these "creations of demons" beneath its iron hooves, Lin Yuan stands atop a newly assembled hot-air balloon and waves at the packed ranks below.
"Brothers, let's show them..."
"What a dimensionality-reduction strike looks like."
