Lin Fan didn't waste any time and didn't take things slow like he did with the first cultivation realm.
Since he knew that there would be another player that would be acting against him, the only thing he could do now was build as quickly as possible, especially since he was up against the zergs. The Bug Race were quick to generate new units, so he had to prepare for the possible zerg rush.
Lin Fan made sure to mark the area that he found the zerg in as dangerous while also making sure to create a line with turrets and troops. He had three marines placed with each turret, that way they could stall long enough for the other troops to come, unless it was a full zerg rush.
Once he was done with that, Lin Fan also created another command center which he sent off in the complete opposite direction. For now, he needed to collect resources as quickly as possible, so he also sent half of his SCVs to help build the new base while creating new SCVs at the old base.
