The elfins did not really agree with Zhang Zian. The bird was too far away, and the probability of catching up with it was not great. Instead of wasting energy on futile attempts to catch it, it might have been better to wait for the next bird to appear.
Nevertheless, he still decided to chase after the bird. He was not sure if another one was ever going to appear.
Old Time Tea prudently put forward another possibility. "Zhang Zian, how do you know that the bird is returning to its nest? If it is out of the nest to search for food, shouldn't it head for the south instead?"
The other elfins had a revelation. They wanted to track the bird to find an oasis, but if the bird was flying away to look for food, it would bring them further from the oasis.
Zhang Zian did not stop working his brain despite his fever. He had reasons for his actions.
He gestured for them to look outside.
