Ch 197: Selection Trial
Rein found himself alone in the middle of a stone room after entering this secret realm. He understood that everyone taking the trials would be separated and had to give the trial all on their own. This was not surprising as Rein had already expected it. So he did not get worried and started to look around the room. Rein saw that there was a stone tablet in the middle of the room with something written in it. He read what was written and found that it was instructions about what he needed to do to pass the first selection stage.
There was a cultivation manual in this stone tablet. Rein needed to study that manual and had to master it to a proficient degree in order to clear this stage. So basically, it was a test to check the comprehension talents of the disciples.
