Hao Xuan stayed around for a few more days to make sure Altron wasn't actually messing anything up, and he wasn't.
Despite his "unique" character once Hao Xuan told the Orcs to follow Altron's directions to the letter, they started taking him more seriously. And how could they not when their savior had given the orders?
Altron was more than a little quirky and a tiny bit annoying but he didn't laze around. In fact he even improved on Baracus's blueprints by readjusting them to the Orcs' specific needs and capabilities.
The timeline for the first facility to be fully up and running was set to approximately 6 months away. And Hao Xuan having observed all he could finally took his leave, leaving the Orcs to strip the city and nearby forests and mountains for resources with Altron guiding them and expanding on Baracus's efforts.
