Ling Han found Chi Menghan and told her about the situation.
Only after learning the Spirit Diagram could one truly grasp this kind of high-level energy and turn it into an instinct, and would not be unable to use it just because one's memories had been erased.
This made things difficult. This was because Chi Menghan and her sister had already cultivated nine types of nine-star high-level energy, so they couldn't cultivate any more top-grade Spirit Diagrams. This was the restriction of heaven and earth, and even the Ancestral King was no exception.
It could not be helped. They could only enter into the treasure mountain and return empty-handed.
Ling Han began to study the Ice Spirit Diagram. This was also a nine-star Spirit Diagram, and it was what he needed the most at this moment.
As expected, even if it was just for these two Spirit Diagrams, this trip was worth it.
