Under One Person: Feng Shui Master, I Will Protect the Mountains and Rivers with My Own Body

[Under One Person fanfiction + Feng Shui layout + Single female lead/No female lead + Battle of wits]
Yan Sen transmigrated to the world of Under One Person. He had neither the Eight Extraordinary Skills nor a heaven-defying bloodline, only the "Feng Shui Technique" passed down in his family lineage—the Shaking Dragon Scripture.
From a young age, he was led by his father, a "land surveyor," to travel all over the country and see all the mountains and rivers.
In this world teeming with supernatural beings, while others practice Qi to fight, Yan Sen practices Qi to "change his fate."
Wang Ye: "Old Yan, why can't my Feng Hou Qi Men Dun Jia solve your puzzle?"
Zhuge Qing: "Set up an array in front of Yan Sen? He can let me see my great-grandmother."
The old Celestial Master said, "This little brat actually wants to change the fortune of Longhu Mountain to his own?"
Fighting? There's no need to even lift a finger.
He casually tossed down a rusty copper coin, and the concrete ground beneath his feet instantly turned into a swamp.
When you straighten a tilted antique vase, the surrounding gravity instantly increases tenfold!
Given enough time and the right antiques, he can turn the entire world of supernatural beings into an unsolvable "dead end"!
