"Can that... really work?" After listening to Katsuyu's explanation, Jiraiya frowned, clearly not believing Tsunade's Hemophobia could be cured so easily.

But in reality, no matter how much Jiraiya doubted it, the scene before him proved that this method was indeed effective.

When Tsunade saw the blood Raikage spat out, her hand only trembled instinctively for a moment before she quickly adjusted back into form. Clearly, it worked.

Therefore, while developing a special medicine for Tsunade, Orochimaru and Shiro had considered many countermeasures, and in the end abandoned genjutsu that was easy to dispel—non-dōjutsu types only required interfering with Chakra—as well as hypnosis that could easily get punched to death.
