After they all agreed to go to the Sixth-Level Cold Pool, the five of them abandoned their original route and headed to the Cold Pool that was about half a day's journey away.

Generally, when Soul Pet Masters walk in some dangerous areas, they must summon a soul pet with a strong sense of perception to ensure that they won't be attacked by some well-disguised soul pets.
The second requirement is for a soul pet to scout ahead. This soul pet must be fast and smart, as the scouting pet is usually the first to enter other creatures' territories. It should be able to escape safely and avoid accidentally entering the territories of powerful soul pets.
Of course, the most important thing when walking in the wild is to ensure a strong battle-ready soul pet is always by their side, ready to engage in battle at a moment's notice if anything unexpected happens.
