After entering the university, Zhang Yu and Bai Zhenzhen attempted to exchange spirit roots for the first time during the Flying Sword Competition held at Wanfa University. During that exchange, Bai Zhenzhen injected her spirit root into Zhang Yu's body.
The second exchange of spirit roots happened below the earth arena at Sky Sword University, where Zhang Yu infused Bai Zhenzhen with a replicated Green Lotus Sword Embryo, so Bai Zhenzhen's dantian suddenly possessed two spirit roots.
It wasn't until this third attempt that they truly embedded their spirit roots into each other's dantian, signifying a genuine exchange of spirit roots.
Zhang Yu's Yu Linggen began adapting to Bai Zhenzhen's adaptation.
Bai Zhenzhen's True Spirit Root started to adapt to Zhang Yu's adaptation.
The two spirit roots began adapting to each other's roots and bodies, creating new adaptations as the other's spirit root underwent changes.
