Former criminal investigation team member Shen Yan was accidentally involved in the infinite trial field by a strange world due to a suspicious falling case. In the first battle, he met Lu Yan, a cultural relic restorer holding a bronze medal. The two of them had the same half-print imprinted on their wrists, thus forming a life-and-death team. They worked together in the E-class teaching building dungeon to dispel their resentment and take the first step to survive.
The end of the dungeon is not the end. The real world during the rest period hides more mysteries: the bronze medal in Shen Yan's hand comes from the deceased who fell from the building, the ancient books left by Grandpa Lu Yan record the secrets of the "Lamp Holder", and the resentful spirits and fragments of the gate in the trial are all vaguely connected to old cases in real life and the mystery of a century-old disappearance.
While they were in dangerous dungeons such as ancient towns, hospitals, and ancient tombs, they relied on Shen Yan's fighting reasoning and Lu Yan's agency interpretation to escape death; while they were working together to investigate cases in reality, piecing together the past of the Lantern Bearer guarding the world gate, and fighting against the opponents in the trial field and the darkened Lantern Bearer forces in the dark.
Every dungeon pass is a game of life and death, and every exploration of reality unlocks the truth. When the crisis of the collapse of the trial field affects reality, the twin lantern bearers can only hold on to each other and the bronze medal, and go through thousands of dangerous situations side by side. In the end, they must keep the gate of the world safe and return to the world together.
Intention: Standing side by side in desperate situations is salvation, and guarding the fireworks of the world with the power of mortals
