On their journey, Ding Fan taught He Qianyao some fist techniques, and they also encountered some Yuan beasts. After all, this was deep in the forest, so running into Yuan beasts was not surprising. Some of the Yuan beasts Ding Fan encountered were used for He Qianyao's fist technique training. Obviously, those used for training were low-rank Yuan beasts, perfect for He Qianyao to practice.
As for those Yuan beasts above the Fourth Grade, Ding Fan handled them. Clearly, such beasts were not something He Qianyao could deal with, but for Ding Fan, they were very simple. Ding Fan gave some of the beast crystal cores to He Qianyao, as they had little value to him, but for He Qianyao, it was different. Even though they were useless to Ding Fan, they were valuable to He Qianyao.
