During the Wanli period of the Ming Dynasty, mountains and rivers were undercurrent, and strange cases occurred one after another.
Chen Guan, a small official in the county, is good at studying ancient books and is proficient in deductions. He originally wanted to live an ordinary life. However, a bizarre murder case involved him in the whirlpool - the deceased was trapped and killed by a trap engraved with hexagrams, and only half of the broken "Book of Mountains and Rivers" was left at the scene.
This book was left behind by the mysterious organization "Tianji Mansion". It records the mysteries that have not been solved for thousands of years, the secrets of the earth's veins, and also hides the "Mountain and River Bureau" map that can shake the fate of the country.
In order to protect himself and uncover the truth, Chen Guan was forced to join forces with the cynical wandering warlock Bai Jian, following the clues in the book, and entering into many puzzles.
The shocking conspiracy at the water transport terminal, the corpse hiding case in the academy that hides the shady secrets of the imperial examination, the folk tragedy that was covered up by the Nuo culture... Mysteries come one after another, and behind them are more involved the multi-party game between the Qintian Prison, the Mohist legacy, the Feng Shui family, and the remnants of the divided Tianji Mansion.
The battle of wits is endless, and murderous intent is everywhere. Chen Guanyi relied on the wisdom and logical deduction of ancient books to deal with various forces and gradually approached the core. But he discovered that the real secret of "The Book of Mountains and Rivers" is far from being as simple as controlling the world...
This is a thousand-year chess game with mountains and rivers as the chessboard and all living beings as the chessboard. And he has quietly entered the game and has no choice.
