Oh, rude! And uncouth! Well, at the very least, the tickling solves his other problem, because now there's no way his body feels like doing any of that.

It's during one of these spirals that he lets go, and kicks Wei Ying away from him; they'll both have to fall back to the ground, but he is hoping to have enough momentum in his push that he might actually wind Wei Ying or something. He's not actually trying to hurt him.

In fact, this fight might go on a long time precisely because both of them want to fight but neither of them wants to inflict any serious damage.
