Arc 15The Ring Research Institute
Qin Yiguan gathered the materials needed to replace the Ring Research Institute, defeated Bo You’s plans through Timeline Convergence, and took control of the new institute. A flashback then revealed that clones of his adoptive parents had drowned his mother, and Qin began investigating what happened to her body.
- Bo You ordered Lu Guang to kill Guan Liujue and Song Miao, while Jiang Yizhou hid the meteorites and Song Miao told Qin Yiguan she would betray the institute and die seven days later.
- Song Miao’s recording explained that the Ring Research Institute was a time-traveling structure dependent on rare materials, and Qin Yiguan learned she had been taken from the river of time.
- Qin Yiguan saved Dr. House from Lu Guang, learned Song Miao had been defiled, and promised House she would return.
- Bo You sent Lu Guang back to his younger self, but the younger Lu Guang revealed that Qin Yiguan had already killed him, and Lu Guang faded from the timeline.
- Qin Yiguan and his allies collected the institute’s materials across time, including the final pieces from a sound-based parallel universe, while Bo You’s institute deteriorated and Bo You’s health failed.
- Bo You revealed that the institute had cloned Qin Yiguan and ordered Shitian to kill him, but Qin used Timeline Convergence to defeat the attack and free Jiang Yizhou from Bo You’s control.
- Qin Yiguan replaced Bo You’s institute with one he had built in 2122, where the researchers joined his side, and Song Miao helped expose and kill Bo You.
- Qin Yiguan fused with the Boundless One, set the Digital Humans and Shitian on their paths, then revisited his mother’s death and saw Bo You’s clones drown her before one buried her body.
