Lin Yu and Shen Yuan originally lived in the real world, but were accidentally bound to the "Doomsday Survival System" and were forced to enter terrifying dungeons full of dangers, such as zombie sieges, weird campuses, etc. Each copy has a time limit. Once the task expires and the task is not completed, it may face elimination and suffer unknown consequences. After entering the dungeon, there is a live broadcast ball following them all the time to record their actions in the dungeon. It will only be turned off when taking a break. There is a live broadcast room in the live broadcast ball, and there are unknown viewers inside who are observing their movements. The barrage keeps jumping, sometimes reminding them, and there will also be rewards from the audience, allowing them to gain points in the system.
They lacked the ability to face the powerful monsters in the dungeon in the early stage, and the terrifying environment also brought great psychological pressure to them, restricting their actions. They face a dilemma between obtaining the benefits of the copy and adhering to each other's feelings and moral bottom line.
However, Lin Yu relied on calm wisdom to make suggestions, and Shen Yuan relied on force to charge into the battle. The two cooperated tacitly and overcame obstacles along the way. The audience in the live broadcast room was enthusiastic about their interaction and rewarded them wildly.
In the life and death tests, their relationship quickly heated up, and they changed from teammates fighting side by side to close lovers. At the same time, they met reliable friends such as the witty Su Ming, the honest Zhao Gang, and the ghostly Yunmeng, and together they wrote legends in the infinite world. In the end, not only did they successfully cope with all the dungeon challenges, but they also continued their sweet love after returning to the real world.
