If it was a human was to make such a cry, Kant could have thought that the other party was expressing his desire to become stronger, a determination to strive to become stronger.
However, for this goshawk, it could not be interpreted from a human's perspective.
Kant had only transformed the goshawk's thoughts into human words, so that he could understand them. In fact, the goshawk's meaning through its will was very clear and straightforward.
It wanted to become stronger. It was not a form of determination, nor was it expressing its desire to Kant. Instead, it was clearly reminding Kant to make it stronger, just like when it had extraordinary powers.
Kant suddenly had a thought. When he had not activated the special effect of Nature's Favor, he seemed to have a faint connection with the goshawk's will. However, because he had not integrated into nature, he was unable to truly communicate as he was now, without any obstacles.
