'I should cross check again for futher confirmation.'
Kai used his [Cosmic Awareness] ability to find clues about the disappearance of the fragment.
He spread his Will Power to the surroundings and resonated with the mountain itself to obtain information about the past six months.
Currently, obtaining information from six month was the limit of Kai, which should be enough for him to solve the mystery.
Soon, Kai got all the necessary information.
'So, the fragment would only appear once a month.'
The fourth fragment didn't disappear or taken away by some beasts, it is still in the peak; but hidden deep inside the core of mountain.
It would only appear at the surface once a month to absorb energy, and it would hide inside the mountain at other times.
With confirmation about the existence of fragment, Kai decided to wait with a peace of mind. He created a concealment formation at the corner and sat inside it to cultivate.
