Dual Transmigration: Apocalypse Overlord, Urban Tycoon

After finishing his food deliveries, Lin Li grabbed a milk tea and transmigrated.

He woke up in the body of a third-year college student. From the start, his younger sister was gravely ill and his girlfriend had broken up with him.

Luckily, after transmigrating, he gained a System. In the apocalypse, he could obtain gold, mutated herbs, and enhancement potions.

In the city, he trades for resources, becomes a miracle-working doctor, and begins a life of luxury.
