In the year 1587 of Feishili (Monster World), the Wolf Clan and the Snake Clan invaded the Yu Clan's territory in order to compete for the Yu Clan's treasure, the Thousand Demons Reversal Talisman. The Yu Clan was caught off guard and was about to be defeated. They used the power of the He Clan to sacrifice Xin Yunzhan to open the door to time and space. The Yu Clan's great elder He Changfeng and the Wood Clan's elder Xie Wuhuang carried 1,000 Yu Clan eggs and 1,000 Flower Clan seeds respectively to the Changchuan area in the parallel plane. In 1518 of the ancient calendar (human world), He Changfeng, the great elder of the Yu clan, and Xie Wuyou, the elder of the Mu clan, brought the descendants of the Yu clan and the Mu clan to the Changchuan area of the human world, and used Qianchen Lu to spread the barrier and thrive here. In 2103 in ancient times, the Institute of Special Events of Country W discovered the place where the Yu and Mu tribes had lived in seclusion for a long time by tracking special events. Due to the language barrier between the two parties, a small-scale conflict broke out. Later, because of the arrogant strength of the elders of the Yu Tribe, the top leaders of Country W reached an agreement with them. A nuclear leak occurred in the Kuchunagawa area and the residents of the area were evacuated, and the Yu and Mu tribes were allowed to live here. The price was that the Yu and Mu tribes had to send stronger young people to cooperate with the Institute of Special Events to quell the chaos caused by the occurrence of special events. But at the same time, in the demon world, the wolf tribe used the remaining Yu tribe to study the use of Xin Yunzhan, and sent several advance members to the human world to create trouble in the human world in the hope of finding the remaining members of the Yu tribe and the Wood tribe and seizing the Xin Yunzhan. A dispute was about to break out.
In the year 2105 of the ancient calendar, the Thousand Demons Reversal Talisman was stolen. The Yu tribe and the Wood tribe, headed by the male protagonist He Linshui, left Changchuan and cooperated with the human government while searching for Xie Wushu who disappeared with the Thousand Demons Reversal Talisman.
