Although Ye Mo wanted to meet up with Song Yangzhu and company immediately, he didn't follow his impulses. His wounds weren't healed yet. He had to heal up first.
Pei Hai City was out of North Far State. It was tens of millions of kilometers away from River State City. If he just went there without a plan, he wouldn't be able to get there fast, and he might even get hunted by the Ghost Immortal Sect.
He knew he had to calm down. Although China Pharmaceuticals' destruction had nothing to do with the Ghost Immortal Sect, that was because they weren't there yet. If they had been the ones to come, Li Yuqian and the others wouldn't have been able to get away even if they had the teleportation formation.
