Hearing Lu Xiaoci say this, He Pingsheng suddenly thought of something.
Back in the lower realm, He Pingsheng had encountered two bottlenecks in every major cultivation stage.
The tenth layer and the eleventh layer.
Each time, he had needed two different kinds of Heavenly Materials and Earthly Treasures to break through.
But later, he had learned that using Heavenly Materials and Earthly Treasures to break through bottlenecks was ultimately not the best choice. It had flaws.
If those flaws remained buried in his cultivation, they would accumulate over time and eventually damage his Daoist Law.
So He Pingsheng asked, "Senior Sister Lu, are there flaws in using Heavenly Materials and Earthly Treasures to break through bottlenecks?"
"Also, if we don't use Heavenly Materials and Earthly Treasures, can we break through in other ways?"
Lu Xiaoci said, "Flaws?"
"I've never heard of any!"
He Pingsheng nodded. Lu Xiaoci had never heard of them, but perhaps that was because she did not know, not because there were none.
Just as he himself had never heard of them back in the Cultivation World. Only after reaching the Spirit Realm had he heard the Great Order Wisdom King and the Vermilion Bird Demon Emperor mention them.
"As for breaking through in other ways, theoretically, it's possible!" Lu Xiaoci looked at He Pingsheng and said, "Without Heavenly Materials and Earthly Treasures, going through life-and-death experiences, gaining insight into certain important truths, and so on could all let you break through a bottleneck!"
"Of course, some exceptionally gifted people have no bottlenecks at all!"
He Pingsheng nodded. It seemed the rules here were largely the same as those in the Spirit Realm.
Then he could surmise that using this ten-jiachen ginseng to break through a bottleneck would probably leave hidden problems and Dao injuries as well.
