Lin Yi wanted Jin Weifeng to hunt sea beasts outside of the map. That area was mostly the territory of peak-stage and peak-stage golden core realm sea beasts. Nascent soul realm sea beasts were not rare, and with Jin Weifeng's strength, it would be a good training for him to hunt alone. Duanmu Yu, on the other hand, was in the map. Although there might be nascent soul realm sea beasts, most of them were still mid-stage and peak-stage golden core realm sea beasts. The effect was the same as Jin Weifeng 's.
Lin Yi himself was in the middle of the two, ready to support them if anything happened. With the flying spirit beast sent by MA Mingyuan, Lin Yi could guarantee this.
