Chang'an City, Xuandu Temple, there is a young man who cannot live to be twenty-four years old. He has a balance seed and yin and yang in his body. Everyone regards him as a disaster star, a key, and a waste that will not live long. Only Yun Ying, the girl with the gun, was guarding him and guarding the fireworks in Chang'an.
In order to win the three-year contract, he traveled across the five realms, looking for seven Heng Keys, and broke through Tai Chi Dao one realm after another. However, the seven keys are about to come together, and the heaven and earth are about to return to zero - the Hengtian ritual is restarted, and the Wuxiang Sect wants to return all things to chaos.
In this battle, he locks Yin and Yang, and she guards Chang'an. The young man used Tai Chi to ask, and the girl used a spear to cross the world, risking her life and longevity to keep the last line of balance in the world.
