The Chaos Qi inside Ling Tian could nourish many Heavenly Treasures, whether they were immortal-grade or divine-grade. But the Enlightenment Sacred Tree was sacred-grade, and the Chaos Qi he had now might not be high enough in grade. After all, sacred-grade things needed nourishment of a similar grade.
Having thought it through, Ling Tian nodded. "Mm, maybe it really isn't high enough. I wonder when it will be. Otherwise, even if I obtain the Enlightenment Sacred Tree, it'll be hard to keep it alive."
"The Enlightenment Sacred Tree doesn't need anyone else to nourish it. It can draw on the Heaven and Earth Great Dao Power to sustain itself. That's why it can condense leaves containing fragments of the Heaven and Earth Great Dao and various Law Powers," Po Tian said. Then his tone shifted. "Of course, that's under normal circumstances. If it's injured, that may not be enough. It'll need a special environment and items to heal."
Before Ling Tian could speak, he continued, "By the way, things of the Enlightenment Sacred Tree's caliber have another ability: they can refine all kinds of energy, such as various types of Origin Power and Chaos Qi. That way, they can reach the grade they need."
"It can refine all kinds of energy?" Ling Tian was slightly taken aback, but then he understood. "The Enlightenment Sacred Tree can draw on the Heaven and Earth Great Dao Power to condense leaves containing fragments of Great Dao Power and various Law Powers. It's no surprise that it can refine energy, too."
"Ling Tian, let me remind you: if you ever get the chance to encounter something like the Enlightenment Sacred Tree, don't let it see that you're thinking of taking it. Their spiritual senses are incredibly sharp—even much sharper than the Nine-Colored Ice Lotus.
