At two o'clock in the morning, Lin Feng stood downstairs in the old apartment and counted the floors - the twelfth floor.
Common sense says that this building only has twelve floors, but there is a small red light on the elevator display, which is the "node" mark. When the elevator stopped at the non-existent 13th floor, a hole was torn open in Lin Feng's world.
The door was locked from the inside, a strange message appeared on the pop-up window of the phone, and a soft wall suddenly appeared in the room.
Behind the wall are his parents who have been missing for three years.
Outside the wall, there are dark forces that want to tear apart the city's nodes.
The martial arts editor is activated, and the novice task is released - find the first node within 24 hours, or clear the memory if it fails.
This is Lin Feng's first night as the "Node Night Watchman", and it is also the city's first battle against dimensional invasion.
