บท 3879: Thousand-edge Demon Monarch Arrived

Although Thousand-edge Demon Monarch and Demon Master Blood Rain had been searching for Jian Wushuang in this area, they did not use their soul power to sweep the area.

After all, they were worried that they would alert the enemy and let Jian Wushuang escape.

Therefore, they had been asking and investigating step by step for the past few years. Until now, they did not use their soul power until they knew Jian Wushuang's approximate location.

The Eternal Dark Prison also had a lot of restrictions on the soul power of cultivators. For example, in the Eternal Dark Prison, Jian Wushuang's soul power could only cover an area of 100,000 miles. However, this was because Jian Wushuang was only a Principles Master, he was not a Ruler yet, so his soul power was not as strong as before.
