My Master's Deadly Mission: Go Down the Mountain and Fetch His Granddaughter

Bound by my master's orders, I, Su Muchen, the only heir of the Heavenly Gate, am forced to descend the mountain and “marry” the granddaughter my master told me about, Lin Wan'er, whom I've never met. She thinks I'm some poor guy trying to marry above his station and gives me a one-year challenge: make it on my own. Little does she know that I can protect an entire nation with one hand, and a single stomp from me can shake the whole Blue Star three times over. Fine. I'll set myself a small goal: build a business empire for fun within a year. From then on, an invincible legend emerges in the city. Underground kings bow to me, business tycoons become my underlings, ancient martial arts sects steer clear of me, and beautiful confidantes surround me. When the long-vanished Heavenly Gate rises to the pinnacle of the world once more, with the cultivation forces of every country under its command, Lin Wan'er finally realizes that her fiancé has long since become the most powerful man in the world. But beyond the stars, “Reapers” from the depths of the universe are quietly drawing near... I thought this would be a carefree urban adventure, but I never expected to become the savior of the Blue Star.
