Two days of running had made Green tired, so he went to sleep for awhile. Since he had bought the seeds, there wasn't anything else for him to do right now.
Zhao knew that Green was back, but he didn't hurry to wake up Green. He knew that Green was working very hard these days. Zhao was crystal clear on how long the road is from Stony Mountain to Casa city. It was because of this that he didn't bother Green, and let him have a good rest.
Zhao was also relaxing. Once he had harvested the crops inside his space, he also didn't have anything else to do. Gathering the stones and making the mill stone wasn't his job.
Zhao was too weak. He couldn't lift anything heavy, let alone doing physical work. But he did bring some crops out of the space as food, greatly increasing the motivation of the slaves.
