Chu Zhiyuan appeared in his small courtyard, his expression solemn.
When he saw Hu Yunni again, her cultivation had faintly improved.
Clearly, her cultivation had advanced again.
Such a rate of cultivation was truly terrifying.
To Hu Yunni now, he was the finest prey.
How could he eliminate this threat and kill her?
A figure like her would surely become one who led the Demon Realm in the future. Eliminating her would be equivalent to weakening the Demon Realm.
But Hu Yunni was indeed difficult to kill.
He stood in the center of the courtyard, frowning in thought, then finally shook his head.
He still had to go to the Demon Realm.
As the level of the Heavenly Dragon Incantation rose, the power required for further advancement became increasingly immense.
Killing over two hundred Demon Race experts and absorbing their demon crystals was far from enough to advance the Heavenly Dragon Incantation by one level.
After carefully considering it, he judged that to push the Heavenly Dragon Incantation to the Seventh Transformation, he would need at least another two thousand demon crystals—and top-grade ones at that.
If they were ordinary demon crystals, he might even need ten thousand.
And that was only the Seventh Transformation. He truly could not imagine how many demon crystals it would take to push it to the Ninth Transformation, or even perfection.
Hu Yunni regarded him as prey, while he regarded the Demon Race as prey as well.
As this thought arose, killing intent flashed through his eyes, just as Fu Zheng arrived with light steps.
Seeing him like this, she hurriedly asked, "Your Highness, what happened?"
Chu Zhiyuan shook his head. "How are things over there?"
"We still haven't found a solution." Fu Zheng sighed helplessly. "We can do nothing about the Ice Jade."
