All things have emotions.
Even the gray wolf, often seen as heartless and cold-blooded, is no exception.
It's just that often times, people do not understand the way they express their feelings.
Take Wang Chen's situation at the moment, for instance.
If he hadn't heard the stories from Grandpa, he probably wouldn't have known that when a male wolf offers a tooth, it is a sign of acceptance of friendship.
Such things, unless experienced firsthand, are unlikely to be believed, that a person could actually become friends with a wolf.
However, Wang Chen didn't plan to make others believe it because he never intended to talk about it.
After putting the wolf's tooth in his pocket, he ripped a cloth strip from his worn-out clothes and wrapped it around the wound on his arm.
In the summer, wounds can easily become inflamed, and although it was not deep, if left untreated, it could cause Wang Chen a lot of trouble.
