Constructing such a large prohibition array is no joke, Lin Yifan must expend a lot of mental power and cultivation power to succeed.
He does not plan to do it in one go, so he chooses to take it slowly.
In the days that followed, he built the super formation and concentrated on cultivation to enhance his strength.
There was nothing to worry about outside, and he wanted to stay here for a while until he completed his plan.
A month passed, and Lin Yifan hadn't come out from underground. The Medicine Saint, who was waiting outside, was puzzled. He didn't know if something happened to Lin Yifan or if he secretly slipped away after obtaining the Green Immortal Ring.
To solve the puzzle, he decided to go into the cave to find out.
Descending into the cave, he saw no one and didn't know where Lin Yifan went.
However, a few footprints left on the ground proved Lin Yifan had been here.
"Strange, where did he go? Did he go in?"
