This cabin wasn't similar to the other rooms, as Shi Yan couldn't push it open, with its door having a barrier. Also, this dark green door was somehow specially customized with a faint halo glowing and moving on it.
The power of the barrier on this door had prevented Shi Yan's Soul Consciousness from sensing the interiors. In other words, Shi Yan had missed this cabin all this while.
Shi Yan immediately confirmed that the one inside this cabin was a special human cauldron. He couldn't press down his curiosity, studying the barrier on the door. Shi Yan sent his Soul Consciousness to observe the structure of the barrier.
Making barrier was a method of using energy to build formations. Different energy intensity levels would create different functions of a barrier.
