"Hmm," Colin nodded, etching the information deep into his mind.
Though Nasi's memory seemed somewhat fragmented, she had not told a lie yet.
As for the danger… the appearance of this Different Space alone was enough to keep him on high alert, even if Nasi hadn't mentioned it!
He returned to the interior of the Tree Hole, but instead of examining the other trees, Colin immediately entered a state of training.
According to Nasi, the Dark Red Wind would blow once every seven days. During the wind, he had to find a place like the Tree Hole Forest to withstand it.
If the worst-case scenario occurred, and he didn't find a similar place on the mountain highlands, when the Dark Red Wind invaded again on the seventh day, he would need to return to the Tree Hole Forest to resist the winds.
Given his speed, it would generally take two days to reach the Strange Mountain, and four days for a round trip.
Thus, he really only had three days available for exploration.
