Although Divine Emperor hadn't brought it up himself, Shen Wei had thought of it. He wanted to ask Ling Tian not to place soul restrictions on Sacred Heart Sect's cultivators. After all, this concerned the dignity and freedom of the sect's disciples. Ling Tian agreed without hesitation. As he'd said, Sacred Heart Sect had helped them, especially now that the sect had joined them of its own accord and brought them so many benefits. He had even less reason to place soul restrictions on its cultivators. To do so would surely be repaying kindness with enmity.
In truth, Ling Tian didn't want Sacred Heart Sect's cultivators to risk their lives alongside him. That was so even though Divine Emperor and the others were powerful. He knew that even with many powerful cultivators helping them in the future, they wouldn't have much confidence in defeating the Lord of the Universe. And if they failed, there would be only one outcome: death.
Ling Tian was willing to die to save Hua Min'er and the others. But he didn't want these "innocent" people from Sacred Heart Sect to die alongside him.
Ling Tian also made it clear that he trusted Shen Wei completely and wouldn't suspect Sacred Heart Sect of having ulterior motives.
If other cultivators had said this, some people would surely have doubted them. But no one questioned Ling Tian's words. After spending so many years together, everyone knew what kind of person he was. They didn't believe everything he did was an act, so they trusted him deeply.
Since that was settled, the matter was put to rest. All that remained was to wait for the cultivators from Sacred Heart Sect and Thunder Strike Sect to arrive. After Divine Emperor made his decision, Lei Ba soon made his as well.
