Under the gray bricks and gray tiles, a secret map that had been sealed for centuries was revealed as the ancestral house was renovated, and an adventure spanning ancient and modern times began. Feng Yichen, a 28-year-old Feng Shui master, wears a black robe that hides the secrets of the compass. He is not only the last lantern keeper of the Kanyu family, but also a wilderness ranger who is keen to explore mysteries. When the astrological totem on the fragment coincided with the modern longitude and latitude, he resolutely stepped into the unknown realm shrouded in fog.
Genius mechanic Yun Ting accompanied him with a self-made precision detector, and gears and steel turned into weapons to break the situation in his hands; the mysterious woman Luo Xuanji was looming in mysterious clothes, and she could penetrate the mechanism by tracing ancient hexagrams with her fingertips. The trio is like a wonderful symphony of heavenly craftsmanship and magic, but they don't know that the seeds of suspicion have already been planted between them.
Deep in the wilderness, the giant bronze door is engraved with the lost secrets of Feng Shui, and the quicksand trap hides a thousand-year murderous intention. Feng Yichen initially relied on the ancestral compass to deduce the direction, but he repeatedly encountered obstacles due to strange geomagnetic anomalies. When the shadow of death approaches, he boldly integrates quantum mechanics with Yin Yang and the Five Elements, uses magnetic field deflection to break the Feng Shui maze, and lets the compass pointer and laser locator jointly guide the direction in the fog.
As the legendary Feng Shui wonders were solved one by one, the price also followed: Yun Ting was seriously injured trying to protect everyone, and Luo Xuanji's true identity gradually emerged. When the fire of civilization encountered an ancient curse, the collision between the compass and the circuit board finally revealed the shocking truth hidden behind the fog - this adventure was actually a trial set by the ancestors a hundred years ago to protect the fire of civilization.
