Perhaps it was because of the limit of its power, despite possessing the Demesne of Space, the Three-Eyed Sacred Demon's power over it was not very powerful.
Otherwise, it would not only have one-third of its health left after fighting with Jiang Feng.
If he were to solo it, even if the Three-Eyed Sacred Demon only had a bit of health left, Jiang Feng would not be able to beat it.
The Demesne of Space was named the strongest in terms of defense, and the second strongest in terms of offense after the Demesne of Destruction.
If Time Stop was not still in cooldown, he would still have the opportunity to kill the Three-Eyed Sacred Demon. Unfortunately, without Time Stop, he was not even able to get close to it.
As he was out of options, he had no choice but to summon Red Boy and Ling Luo over.
"Ling Luo, Red Boy! To me!"
