After meeting Feng Lingzi and the Young Leader, Ling Tian brought up the idea of giving them the Phoenix Soul Fruit and explained why: they were still young, with an abundance of life force, and could easily live for several million more years. That was plenty of time for the Phoenix Soul Fruit to bear several more ripe fruits.
Besides, Ling Tian and the others had no need for the Phoenix Soul Fruit right now, nor would they for a long time. After all, having them use it now to undergo nirvana and be reborn would be a waste. It would be best for them to use it when their life force was nearly depleted; that would also improve their strength more.
Though they knew Ling Tian and the others had a point, Feng Lingzi and the Young Leader still refused. They wanted to save it for others, such as Wu Ling and Bi Yun. After all, in their hearts, those people had a better chance than they did of breaking free from the Lord of the Universe's constraints and becoming saints.
Ling Tian remained insistent, but he couldn't persuade Feng Lingzi and the Young Leader anytime soon.
In the end, Po Qiong sent Ling Tian and the others away, then personally tried to persuade Feng Lingzi and the Young Leader. His reasoning was even more convincing: if Feng Lingzi and the Young Leader used the Phoenix Soul Fruit to undergo nirvana and be reborn, their strength would increase. When they challenged the final tribulation in the future, they would cause the Lord of the Universe even more trouble.
That was right. Po Qiong's excuse wasn't all that different from the one he had used to persuade Ling Tian. The stronger Feng Lingzi and the others became, the more trouble
