The old vendor was very efficient. After Chu Mu handed over five gold coins, he lifted a Soul Technique Book from a pile of assorted stuff.
Soul Disciple's Soul Technique Books were thin, like special scroll paper. All Soul Technique Books could be said to be consumables. Once a Soul Probe is performed on a Soul Technique Book, the way for applying the documented soul technique would be etched into the memory of the Soul Pet Master, and the Soul Technique Book would naturally lose its effectiveness.
Opening a Soul Technique Book required the expenditure of Soul Power. Chu Mu would have to wait until he'd fed the White Nightmare Demon before he could open this Soul Technique Book.
Then, Chu Mu bought a dual attribute soul nucleus of beast attribute and fire attribute from the old vendor, ensuring food for Mo Ye's training in the next ten days.
The last gold coin was used to buy two bottles of Level 2 Low-Efficiency Healing Elixir from a pharmacist and used for healing Mo Ye.
