After Zhang Yuyan reshaped the "Guardian of Time and Space Agreement", the brief peace was broken. The remnants of the Wang family digitized their consciousness and sneaked into time and space to tamper with history. A mysterious organization called "Time Ruins" surfaced. It mastered the taboo secrets of controlling memory and blood, and attempted to refine time and space to achieve immortality. Zhang Yuyan and the five fathers reunited and embarked on a journey to restore time and space.
During the process of guarding, Zhang Yuyan's Qilin bloodline was repelled by the agreement. Every time she used her power, she would witness the tragedy of the parallel world, and her fathers also faced the difficult choice of guarding her and guarding the order of time and space. As the investigation deepens, the civil strife of the Zhang family thousands of years ago, the rise of the Wang family, and the mystery of Zhang Yuyan's time travel are all closely related to the "Ruins of Time".
The final decisive battle took place at the core of "Time Ruins". Zhang Yuyan used the love and faith of everyone to weave a new protective network and purify the laws of time and space, but she also lost part of her memory. A hundred years later, the remnant party of the time ruins was reborn with the power of "regret", controlling the reverse flow of cause and effect, and the five fathers and one child faced off again. This time, they discovered during the confrontation that the countless warm moments given to Zhang Yuyan by her fathers were the key to solving the crisis. After many tests, everyone integrated their beliefs into the laws of time and space, and completely defeated the time ruins. Zhang Yuyan also transformed into the eternal guardian light, continuing to write the legend of the guardian of time and space.
