The 90s Coal Tycoon

Reborn in 1990, Easton Linden spends his entire three years of savings to contract an abandoned, flooded mine, only to be dumped by his fiancée and ridiculed by friends and family. Using memories from his past life, he breaks through a rock layer deemed hopeless by the geological team and unearths a prime anthracite coal seam. He leverages a cold wave to rise against the odds, breaks a monopoly, weathers an economic winter, and finally builds a business empire spanning the energy sector.
