Endless Inner Strength

There is a mouth on Zhang Yu's left hand. This mouth can swallow other people's internal energy, and it can also swallow the elixir of heaven and earth. The internal energy is like the sea, and it can naturally defeat all magic with one force. Regardless of your exquisite swordsmanship, I will break it with one force. No matter how erratic your body skills are, I will break it with one force. With your magical power protecting your body, I will break it with one force. In the way of a warrior, internal strength is king.
