Neither of them had expected that in their battle here, Zhao Hai would gain the upper hand in the end. Whether it was the cultivators in the cloud Sea realm or the myriad realm battlefield, as long as they died, Zhao Hai would choose some and pull them into the space to become undead creatures. He would also bring their weapons into the space and make them his subordinates.
Of course, Zhao Hai didn't dare to go too far. If the people in the cloud Sea realm and the myriad realm battlefield found out that all their dead cultivators had disappeared, wouldn't they immediately become suspicious? thus, Zhao Hai only pulled a portion of the longevity stage cultivators into the medium, and there weren't many of them.
This great battle lasted for a few months. In the end, the myriad realm battlefield could not hold on any longer. They had lost too many experts, and they had no choice but to retreat.
