After cultivating the Iceheart Technique to the fifth level, his mental power had increased by a large margin. Zhu Wuwan only needed to adapt to it for a while before she began to upgrade the Iceheart Technique again.
The speed at which the Vast Sea Essence Crystals increased was so fast. If he did not open his Niwan Palace earlier and increase his mental power, Zhu Wuwan would not be able to condense the Vast Sea Essence Crystals to the limit in time. At that time, it would be inevitable that he would waste the breakthrough point.
Wasting was shameful, especially when it was a treasure like the breakthrough point.
"Congratulations to the host for raising the peerless mental cultivation technique, the Iceheart Art, to the sixth level for the first time in his life. You have obtained 80 million breakthrough points…"
An hour later, the Iceheart Technique was upgraded to the sixth level by Zhu Wuwan, and his mental power had more than doubled.
