However, everyone knew that once a soul was seriously injured and didn't heal for a long time, the consequences would be extremely serious.
The injury wouldn't heal itself. Instead, it would get worse until it started to affect the martial warrior's cultivation. Their realm would stagnate and they would finally die.

Normal martial warriors wouldn't be able to cultivate this secret skill.
Only powerful presences like Ruler Xing Yun, Devil Titan Shi Xue, and Devil Titan Gula had the ability to cultivate the corresponding secret soul skills because they had a strong foundation.
Yet, Wang Teng was able to reach the well-versed stage without putting in any effort.
This difference was enough to make an eternal-stage ruler unhappy.
What's more, they took much effort to get these secret scriptures. They were all secrets that couldn't be passed down to others.
