• Battle Armor research: With the Crown Prince’s approval and imperial resources, Gu Yuejin’s team develops a prototype that links a Soul Tool directly to its wearer. Its first public combat test takes place during the tournament quarterfinals 68 101.

Imperial Politics

Xu Tianran seeks to recruit Gu Yuejin after recognizing his strength. Gu Yuejin accepts a senior academy position but declines the Crown Prince’s later offer of a royal advisory title, leaving open the possibility of future cooperation 28 32 53.

The empire’s backing of Gu Yuejin’s work also has political consequences: Jing Hongchen’s decision to accompany the tournament delegation places Mingde Hall visibly behind Xu Tianran 73 77.
