Getting to this Ice Pole region, the coldest place in the human realm, was not an easy feat. Chu Mu wanted to give his Ice-Feathered Spirit the most sufficient training.
Since the Ice-Feathered Spirit had advanced to the High-level Emperor rank, it could be considered the most powerful in the soul pets currently owned by Chu Mu. Even though it still bore some injuries, Ning didn't get complacent and instead continued to polish its abilities and adjust to new powers in this frozen world.
Teng Lang, however, was complaining all the way. He himself intended to graduate to the High-level Emperor rank, but Chu Mu unexpectedly achieved this breakthrough instead, leaving Teng Lang in all sorts of jealousy and envy.
Suppose Teng Lang did not manage to timely attain this High-level Emperor realm; his power would definitely lag further and further behind Chu Mu's in a matter of a few years.
