On a snowy and windy night, a thrilling life-and-death struggle began in the ruined temple surrounding the "Tianji Tu". A young man in ragged clothes would rather die than give in. He took poison to protect the secret map, and then the mysterious man quietly took it away. Immediately afterwards, the old beggar was accidentally involved, which revealed the deeper secret behind the secret map.
After the county government watchman discovered clues to the Tianji Diagram, the county magistrate conducted an in-depth investigation and found that it was related to the mysterious stone tablet on the barren mountain outside the city. However, the men in black sent by the village owner secretly obstructed the situation. The conflict between the two sides continued to escalate, and a fierce battle broke out on the barren mountain. The county magistrate was seriously injured in the battle, and the secret map and fragments of the stone tablet were taken away.
After the surviving county magistrate recuperated in the inn, he embarked on the road to the capital, hoping to use the power of the court to regain the Tianji Map. On the way, he found new clues from the fragments of the stone tablet, but was pursued by a mysterious man in black. In the process of evading pursuit, can the county magistrate save the day? Can he successfully find the old man, regain the secret map, and avenge his dead brothers? What earth-shattering secrets are hidden behind the Tianji Tu, and what kind of changes will it cause?
