Within a few days, Chen Heng left the area he was in charge of and headed to another area. To him, this wasn't too difficult of a task. The Guardian's duty was to guard the safety of an area, but this didn't mean that a guardian couldn't leave the area he was in charge of.
Strictly speaking, normal behavior was fine as long as there were no violations of the rules and bad consequences. Generally, there would not be any problems for Chen Heng to leave the area that he was guarding.
Of course, if something happened to the area he was guarding during Chen Heng was away and caused bad consequences, that was a different matter.
However, the probability of such a thing happening was not high. Unless one was too unlucky, it was unlikely to happen. Chen Heng was the same.
