"What was that?" Yu Nianzhen suddenly exclaimed and looked back.
As soon as he crossed from land to the abyss, he felt like he had passed through a thin film.
The film was a little cold and left his body feeling cooler than normal.
However, when he looked back, he saw nothing.
There was no film and his divine sense didn't detect any abnormalities.
At a loss, Yu Nianzhen took a step back, planning to experience the sensation again.
Unfortunately, things didn't go as planned.
When he tried to get back to land, his foot landed at the edge of the abyss and couldn't step on the land.
"Did I step into a formation?" He muttered and refocused his divine sense.
The divine sense examined the area around him but he still didn't find anything.
At this time, a soul beast flew out from the soul raising tree and cantered towards him.
The soul beast was at the fourth level and Yu Nianzhen tensed when he saw it approach.
