The souls of those who had been searched by him were not only reduced to ashes, but even their bodies might not be able to be preserved. That was why Jacob had been very careful about using the Soul Searching Technique, because he felt that this method was a little heaven-defying and went against his conscience.
From the incomplete memory of this cannibal, Jacob finally figured out the pattern of this place. He also figured out that there would be a party that was held once every ten years by the cannibals. They would hunt everywhere and lock up all the captured people. Then, they would wait for an opportunity to use the living people as sacrifices to carry out their once-in-a-decade ceremony.
That method was too cruel. In the memory of that cannibal, Jacob saw the grand ceremony that was held ten years ago. He couldn't bear to look at the bloody scene directly.
