Bab 251: Laboratory: Krieg's Chamber of Secrets (2)

This looks like some kind of hidden compartment that can be activated by pressing it.

Ji Chen didn't let his guard down in the slightest. He left a Murloc Ranger behind and led the rest of his troops back to the stone door, preparing for any unexpected situations.

After the Murloc Ranger pressed the brick, accompanied by a scraping sound, a section of the wall on the side slowly opened to both sides, revealing an entrance.

Ji Chen didn't immediately approach. Instead, he let the Murloc Ranger go in to investigate.

A few minutes later, the Murloc Ranger emerged, unharmed, and signaled that there was no danger.

Seeing this, Ji Chen walked over with a relieved expression.

In this Lich's laboratory, being cautious was of utmost importance to him.
