With the help of the Eye of Emptiness, Lin Yi walked through this seemingly dangerous Formation as if he were on a casual outing, stepping leisurely. With each step, he landed in the correct position.
Within the Formation, he saw traces of other Cultivators who had been there. It seemed that quite a few Cultivators had accidentally entered this Formation. However, oddly enough, he found no skeletons.
After a while, he stepped into the Formation where Xu Yu Rou was trapped. This was a Five Elements Formation, which would display five different environments, including corresponding attack methods.
Although the scenes that appeared were of Illusion Land, the attacks were real.
Unless one found the correct Array Core, or was powerful enough to directly cause the Formation to collapse, it would be impossible to exit the Formation, even if one survived the attacks from these five illusory environments.
