Haobai and Ping Yunlan were captured in the tower for human experiments since they were children. The two depended on each other. They made an agreement with each other in the tower on the eve of the experiment for the rest of their lives. The next day, Haobai was first pulled to do a brain connection experiment, but an accident happened in the middle. He suffered a brain injury and could not continue the experiment. He also lost part of the memory in the tower and was abandoned in the wasteland. Later, the scientific researchers took Ping Yunlan to the experiment and successfully replaced Haobai and stayed in the tower forever.
Haobai woke up a year later and found that he had been rescued by Sister Jin. A virtual product called "Tower" was becoming popular in the world, and Haobai also participated in it...
Purpose: Happy every day
