As people gathered in Tai Ah Divine City, Yi Yun was in the sword tomb trying to gain some understanding of the sword truths without knowing the time of the day.
Originally, Yi Yun thought that having experienced the saber tomb, which came from the same origins as the sword tomb, it would be extremely easy for him to understand the sword truths with his entry into the sword tomb.
However, it was only when Yi Yun entered the sword tomb did he realize that it was completely different from the saber tomb.
In the saber tomb, there were saber scar marks and the Saber Truth's 32 Words. Each word contained a saber truth.
But, the sword tomb did not have those things. In there, there was a fascinating stone wall. Closing one's eyes and meditating in front the stone wall would envelope someone in illusions.
