After Peter killed Samuel Carter, he went into the room and realized the Feng Shui pattern used by Samuel was incredibly powerful. The abundant evil energy from the surrounding area had all been channeled into the room, leaving Peter with a chilling sensation as if his whole body was about to freeze.
It had been a long time since Peter had used Body Refining Technique, but now he felt waves of evil energy infusing into him, each pore of his body undergoing a kind of refining process.
Although Peter knew that Samuel had used the evil energy of the dead to refine his body, which was wicked, he found that he could not leave even if he wanted to. The Feng Shui Formation here was originally centered around Samuel himself. The Qi Mechanism was all his own, but with his death, the Qi Mechanism changed, and mysterious energy targeted Peter in an onslaught.
