Convince.

Shi Lang did not bother with anything around him and kept his focus on settling the zerg territory. He could not blindly just swallow sectors and digest them. He needed the forces to defend the regions as well. Thus he pulled back from the command, let Deputy Skiar manage the front, and made a beeline to Mars. 

The red planet had long been terraformed, it was used as the housing and deployment station for the reserve forces in the fleets. This place was like a military planet, they had its own system. The governance was completely militarized but under the supervision of the civil minister. 

Shi Lang had made his way back because he needed to incorporate troops in his fleet and he was not going to pick just all of them in surplus. His ship landed on the ground and he was received by the Military Governor, a rank specially designated for the administrator of this planet. Shi Lang was now the first general of the federation, his reception was high and mighty.
