Last time, when dealing with Musashi-bo, Tang Yi realized his own insufficiencies. Against ordinary people, no matter how tough they were, Tang Yi was confident he could handle them.
However, with unique existences like Musashi-bo, Tang Yi found himself somewhat lacking and without effective means.
Originally, Tang Yi had thought about thoroughly studying the Yin-Yang Talisman, ideally mastering the most important Yin-Yang Seal, as it could suppress Musashi-bo and even the Dragon Vein's Divine Skills. If he could master it, dealing with Spiritual Bodies and similar beings in the future would be effortless for him.
Unexpectedly, the "Ancestral Master's Notebook" directly recorded the cultivation method of the Yin-Yang Seal, which saved Tang Yi a lot of trouble.
However, at the moment, Tang Yi had exhausted his mana. Even with the cultivation method, he could not cultivate without first restoring his mana.
