Aryan also became alert about those monsters. Both of them are currently using your observation technique to observe those monsters who have already come close to their base. Some time ago, Aryan was meditating, but suddenly, his senior sister alerted him about the Monsters.
With this, both of them observed those Monsters but did not attack them. Both of them wanted to be sure whether those monsters wanted to attack them or not. There could be a chance those monsters just came to that place to rest or something like that.
20 minutes later, finally, they can sigh in relief. It looks like those monsters did not come there to attack them. Those monsters are just roaming around.

The next day,
Around 4:00 a.m., both of them came out from their hiding place and decided to start hunting. Finally, everything became visible even though the sun still did not appear in the sky.
