"Senior Brother Xu, how should the essence blood of different Spiritual Beasts be blended with Spiritual Medicines to prevent an excessive reaction?" Sikong Yuanyao spoke earnestly.
"With attributes of the same kind, pay attention to using neutralizing Spiritual Medicines to adjust the medicinal properties."
"For different attributes, blending should be done when the other Spiritual Medicines are in their most stable state, and that depends on your precise control."
As Xu Feng explained to Sikong Yuanyao, he also sent a message to Sikong Yunhai.
"Is your little sister a bit...?"
It didn't take long for the reply to arrive.
"Actually, this isn't a secret at all, I'll just tell you straight. My fourth sister was born with dual souls and needs to harmonize with Yin and Yang."
"She is a little sister during the day but turns into my little brother at night. To separate them, we have to wait until after stepping through the Immortal Sect."
