Yale went to meditate alone after having accepted Merumi as his disciple. As for Kaigur, even though his personality wasn't bad, Yale didn't feel like taking him as a disciple and Kaigur hadn't asked for it either.
Yale was meditating about the Laws he had comprehended, and he felt that he wasn't doing it well.
"The Sword Law, Space Law, Time Law, Life Law, and Death Law are all Laws that I trained in my past life and with the divine bloodlines and the Condensed Essences it is just a matter of time reaching the level of my previous life..."
Yale started to think about that after seeing Merumi's three forms where the human form had the capability of being more versatile in learning Laws than the others that had a guaranteed success in becoming a Law Master in the Water Law.
