After Han Fei was trapped on the Path of No Return, the first thing Shen Le did was to tell the disciples of the Void Temple about the path above the dominator realm, and then to the Death God and the Master of Time.
Now, Shen Le and the undead had disappeared, Han Fei had returned from the Path of Return, and then such a law abnormality erupted in the Sea of Stars. The Death God naturally guessed that Han Fei had made a breakthrough.
Although it was very fast, the Death God wasn't surprised. To be able to find the path above the dominator realm was already something that no one in history could do. Besides, Han Fei had the high hopes of many people.
