The story of a workplace rookie and four male colleagues with different personalities.

The story is set in the Song dynasty and at the beginning of the Jurchen-ruled Jin dynasty's invasion of northern China. The first part revolves around the friendship of two men, Yang Tiexin and Guo Xiaotian, who became heroes in their own right as they fought the Jin invaders. The bond between the duo is so strong that they pledge to each other that their unborn children will become either be sworn siblings (if both are of the same sex) or a married couple (if they are of opposite sexes). The story focuses on the trials and tribulations of their sons after Guo Xiaotian's death and Yang Tiexin's disappearance.

The eyes of the flesh are dim and unclear, seeing near but not far, seeing before and behind, seeing light and not seeing darkness, what they see is not infallible. Xia Dongqing, who does not seem to have any sense of existence on the outside, has an unknown secret. He can see sentient beings in another world. He grew up in an orphanage and had just graduated from university and was preparing for the postgraduate entrance examination. At this time, he was looking for a job. During this period, Dongqing was admitted to the 444 convenience store. It is said that this convenience store will be haunted after 12 o'clock in the middle of the night. It turns out that this is the connecting point of two different latitude spaces.
