From MC's perspective:
Abandoned building,
As the time passed, I realized everyone must be searching for me. A few hours later,
Swish!
I appeared back in the passage and started following the route. Soon, I reached the other end where I arrived in front of a similar door.
Then I probed the gate by using the system. Seeing that there was no restriction on it. I walked forward to open the door.
Creak!
After opening it, I walked inside. The next second, a thick blood of smell attacked my nostrils. I see organs stored in the glass jar and kept on the wooden shelves.
I guess this is the 1st time for me to visit an actual evil lair. Then I started to investigate the place. There might be another secret passage in this room.
Meanwhile,
The level-6 wizard came to the starting point of Abbey Street. Then he found the broken body parts of the evil wizards.
