Transmigrating and Becoming a God Through Dual Cultivation in the City

Multiple female leads, no exclusive pairing, scheming, not a goody-two-shoes, urban cultivation, invincible protagonist, a cultivation-world wage slave named Lin Fan gets caught in the crossfire of a fight between powerful cultivators and dies from the shockwaves. He transmigrates to a modern city, a world without spiritual energy where normal cultivation is impossible. By a stroke of luck, he discovers he can cultivate through a dual cultivation technique. Sigh... This technique has brought me nothing but trouble (smirks)!
