In fact, Yin Liu and Yin Ba were not the only ones sent out. There were also the two Planetary realm powerhouses, Diwu Hui and Diliu Xiaoshu, who had just surrendered.
Yin Liu and Yin Ba went to the settlement planets and resource planets of the Mechanical Spirit Race in the solar system. Other than the Planet Spiritual Sea and Planet Spiritual Cabin that they gave to the Huaxia Race, there were a total of three other planets. Their main target planets were two.
Other than bringing back a portion of the resources, they also had to reunite the remaining species of the Mechanical Spirit Race.
This was one of the conditions that Xu Tui had agreed to Yin Liu's surrender.
Under suitable circumstances, they would give the Mechanical Spirit Race a chance to develop. The Planetary realm and quasi-planetary realms of the Mechanical Spirit Race under Lei Tian had all died. Their main goal now was to gather the Mechanical Spirit Race.
