Jason could have made use of various plans in order to achieve what he wanted inside the second trial.
However, there were too many unknown factors which Jason was unable to find out right now.
Amongst them was the exact strength of the oceanfolk attack wave that was bound to hit them soon.
Other than that, he was also in the dark regarding the combat prowess of the other villages.
This made Jason uncomfortable, but there was not much for him to do about that.
At least, not for now.
He would have to leave the small village in order to find the answers, and this was exactly what he couldn't do without feeling that he would be making a huge mistake.
Thus, Jason decided to follow the easiest plan, which was to only protect the village he was currently in.
There was something else he planned to do as well, but protecting the small Mewi village was his highest priority right now.
