Wasteland Tycoon: Return of the Exiled Heir

Jax, the discarded son of the Sterling chaebol, was assassinated by his family and exiled to the dead-earth wasteland after awakening the completely combat-useless "Planting Ability." Yet he used this "trash" power to grow one-of-a-kind zero-radiation plants on the dead soil. Starting from an abandoned manor, Jax built a "Wasteland Farm," and with divine-tier agricultural products that purify and evolve, he successively tamed catastrophe-tier monsters — a Tier-5 Zerg Queen Bee, a Tier-6 World-Destroying Tyrant, a Mantis Prince, and the Dark Night Spider Empress — as his "executives," establishing an absolute monopoly on force and agriculture. Facing the four major chaebols' biochemical-gas sanctions, the Sanctuary's nuclear cleansing, and even an interstellar strike from the alien Orion Group, Jax — with the swagger of a ruthless capitalist — used his "World Genesis Tree" to reverse short-sell, hostile-takeover, and liquidate them all along the way. In the end, he not only completely destroyed the old world's monopolistic class and reshaped Earth's ecology, but also drove his farm's roots into the deep universe, becoming the biggest business oligarch in the entire cosmos.
