Chương 161: Unknown Source

'This is quite a nice place to build a secret lab.' Alex thought as he walked through the dense trees, following the directions given by the system.

After walking for a few minutes, Alex stopped in front of a tree that looked no different from the tens of giant trees in the surrounding.

'This is the entrance.' Alex thought, looking at a small hole in the tree's roots.

Alex entered the narrow entrances and crawled his way through the narrow passage for three minutes, he reached a small opening, and after going through it, he entered an open area.

Alex looked around and saw that he was in a narrow cave passage with no natural light, and at the end of the path was a four-meter-high stone door.

'This is a 40 Men team dungeon which means a lot of monsters and a lot of levels for me.' Alex thought as he stretched his arms and walked toward the door.
