After a more in-depth analysis, the System had determined that the entire forest was no doubt the body of the Transforming Spider. Jin could not bear himself to spread the news out to the rest of the group here.
"Should the Demon Exorcist Trainees wandered too long in the forest, it would eventually be eaten by the Spider." The System commented.
"You mean the spider will appear to consume them?"
"No. If the predictive analysis is true, the appearance of the forest will consume them when they are caught off guard." The System stated and warned Jin not to mess around with this particular Transforming Spider.
