For instance, in the original story, Lei Wanhe, who excelled at Lightning Release, had further dealings with Han Li because he was collecting spirit herbs.
He even produced a list of ancient pill recipes and let Han Li choose two pill formulas in exchange for two of Han Li's spirit herbs.
Clearly, Lei Wanhe was not only skilled in Lightning Release but also in alchemy, frequently refining pills for his own use.
Now that Hinata and Karin had masters, they had backing and resources, as well as proper cultivation techniques, allowing them to study immortal cultivation systematically.
In particular, they could study alchemy more effectively.
Naruto had never expected Hinata to become Li Huayuan's disciple.
This was a good thing.
And for Naruto, Hinata becoming Li Huayuan's disciple brought tremendous benefits as well.
After learning the news, Naruto instructed Hinata to quietly obtain the Azure Essence Sword Art from Li Huayuan.
The Azure Essence Sword Art was a cultivation technique Yellow Maple Valley had acquired after destroying another sect several hundred years ago. It contained only the first nine levels, allowing cultivation up to the Core Formation Stage.
But its effects were truly unremarkable. Any Foundation Establishment Stage cultivator in Yellow Maple Valley could easily obtain it, and they would practice its first three levels.
That was only because the first three levels included a spell art: Sword Aura.
Sword Aura was reasonably powerful and practical, making it worth learning.
But no one practiced the later levels, because the spell arts and divine powers included after the third level of the Azure Essence Sword Art were utterly ordinary.
Moreover, there was nothing particularly outstanding about this cultivation technique.
It was not the fastest to cultivate, nor were all its accompanying spell arts and divine powers particularly powerful.
Naruto merely smiled
