Border Keeper

Chen Yansong, an ordinary social worker, never thought that his ordinary life would completely go astray on his twenty-third birthday. An unexpected car accident not only did not allow him to receive a box lunch, but instead unlocked the special ability to travel freely between the Yin and Yang worlds. During the time when he first awakened his abilities, he was driven crazy - he could always catch a glimpse of shadows floating around his colleagues when he went to work during the day, and when he came home at night and closed his eyes, he might fall into the gloomy streets of the underworld, making even a sound sleep a luxury. After slowly adapting to his abilities, Chen Yansong discovered that the two worlds of Yin and Yang were not unrelated. Instead, there were countless secret passages that maintained a delicate balance. But as his exploration of the two worlds gradually deepened, he found that this balance was being broken: the resentful spirits of the Yin world began to frequently break into the Yang world to cause chaos, and some malicious intentions in the Yang world were constantly eroding the order of the Yin world. There were even mysterious organizations secretly watching this shuttle ability, trying to use it to achieve ulterior purposes. In order to protect the people he cares about and to find out the truth about his ability awakening, Chen Yansong had to take up the responsibility and live a seemingly normal life in the Yang world while exploring the truth and resolving the crisis in the Yin world. He got acquainted with the guardians of the Yin world and the secluded practitioners of the Yang world. During his travels, he uncovered the origins of the Yin and Yang worlds, the secrets of his family, and the huge conspiracy behind the balance between the two worlds. From passively responding to crises to actively guarding the border, Chen Yansong eventually became the ferryman between the Yin and Yang worlds, maintaining the stability of the two worlds in his own way, and also found his own value in life.
