That was right. In the past, Feng Lingzi and the others had worried that Ling Tian might hide inside an Outer Realm Stone, so they had captured many cultivators carrying one. That way, those cultivators would have no chance to trigger their final tribulations ahead of time. But since the Lord of the Universe wouldn't allow Ling Tian and the others to hide inside an Outer Realm Stone, they could simply carry their stones far away from Ling Tian. That would keep him from controlling them and prevent him from taking away their chance to trigger their final tribulations early.
At that point, however, Feng Lingzi and the others thought of another problem: Hua Min'er and the others also needed to hide inside Outer Realm Stones.
It was true that the Lord of the Universe had stopped Ling Tian and Little Devourer from hiding inside Outer Realm Stones, but he hadn't stopped Hua Min'er and the others. They might not live as long as Ling Tian. After all, Hua Min'er and the others had already used Phoenix Soul Fruits to be reborn through nirvana, while Ye Luo and Little Devourer were still in fairly good condition. If Hua Min'er and the others couldn't hide inside Outer Realm Stones, they would likely have to trigger their final tribulations early because their life force was running low. That was the last thing Feng Lingzi and the others wanted to see.
Although Feng Lingzi and the other older-generation cultivators valued Ling Tian greatly, they also cared deeply about younger cultivators like Hua Min'er. Naturally, they hoped the younger generation would have a better chance of escaping the Lord of the Universe's restraints, and they very much didn't want to see them fall in their final tribulations. They knew, then, how important it was
