A hole?
The hole was clearly left by a whistle beast.
In other words, the giant skull wasn't prepared as a "pathway" for the Whistle Beast Clan. They had to forge their own path.
Was it because the original humans hadn't considered that the whistle beasts would come here when they designed the giant skull?
Or was it because the Whistle Beast Clan had its own agendas, maintaining an outward appearance of harmony with its creator?
A few conjectures popped into Yu Liang's mind, and his speculation about the Whistle Beast Clan gave him a sense of opportunity.
The whistle beast queen once told him that if the Whistle Beast Clan thought their clan was more suited to return to the "Tree", they wouldn't hesitate to betray.
No, this probably couldn't be called betrayal, just a choice.
After all, the original humans had completely entered a state of extinction. Being unable to reproduce, they could see their species' endpoint.
