Main plot:
The protagonist Qin Yin travels to a fantasy world and becomes a night watchman (watchman) at the Imperial Tomb of Daxia. This is an unlucky position that is regarded as a fatal situation. He awakened the "Fishing System in the Heavens" and could fish for treasures from the heavens and the world by "fishing" in the imperial mausoleum late at night (essentially a sign-in flow variant).
In the first few chapters, I obtained the "Ancient Holy Body" and "Sword-Slaying Technique" through fishing, and fished out the weapon spirit (the heroine) sealed in the Imperial Sword of the Imperial Tomb. The protagonist adheres to the "righteousness", shows weakness externally, and accumulates wealth internally through fishing.
In the middle period, the imperial power changed, and external disputes continued. Not only did the princes want to break into the imperial mausoleum to seize the treasure, but there were also demons in the world who coveted the yin energy of the imperial mausoleum. They were all killed by Qin Yin secretly, creating the legend that "there is great terror in the imperial mausoleum".
The climax occurred when the enemy invaded with their troops and the royal family of Daxia was almost wiped out. The enemy swordsman wanted to destroy the imperial mausoleum and cut off the dragon's veins. Qin Yin was forced to end his "fishing" career and walked out of the darkness. With one sword, he killed the sword master in nineteen states and shocked the world. He then refused to ascend the throne and continued to return to the imperial mausoleum to fish for immortality.
