With the power of the spirit book of evolution, Ray could easily access the evolution of Rin's kirin.
Still, he opted not to do that right now.
Evolving others' spirit beast was no small feat, and he didn't really want to attract so much attention.
Just tuning it to win the practical class was enough, and there's no need for Ray to do anything extra.
' Spirit book of evolution, I hope you won't disappoint me.'
Arrays of Data appeared on Ray's mind, and he started to tune the spirit beast.
Actually, the job of tuning other spirit beasts was not that hard.
Ray just needs to make sure Rin's kirin's condition was at its optimal, and if he could, provide some buff to the Kirin.
For a normal high school level research Daoist, tuning was just a formality as they couldn't really give a buff to their partner. They could only make sure that their partner spirit beast was okay, and that's all.
