From MC's perspective:
Time went by,
At the time of dusk, I saw some light ahead. In curiosity, I followed the light. When I got closer. I saw a camp ahead.
The bright light is nothing but a campfire. Seeing that I realized. I have reached another big camp. There must be more than one group here.
The camp was set up in open land space. My appearance will be sensed by others. Suddenly, I thought of something.
The system's new function. No existence can sense my presence without my permission. It's the right time to test the system's new function.
Then I told the system to hide my presence. After doing that, I started approaching the entrance. I hoped no one would come out of their tent all of a sudden.
When I reached the entrance. I got a clearer view of the camp. There are more than 50 tents here. Which means at least 50 wizards in this camp.
