Is Musashi Miyamoto invincible?

In the duel on Ada Island, Musashi Miyamoto finally won Sasaki Kojiro. Although most people focus on Musashi's lateness, provocation and the position of the sun, I don't think it is shameful. Kojiro chose the venue for the duel because the beach was good for his long Dao. It is said that Musashi won by deception. History has always been like this. Just like Cao Cao in the Three Kingdoms, Kojiro's tragedy is really deplorable. But Musashi's second knife flow is not covered, and the outcome is still the second. Therefore, if people are concerned, we think that Musashi is somewhat insidious. We can also think that Kojiro's psychological endurance is still lacking. He was late and provoked this trail to disturb his state, which was broken by Musashi Miyamoto. Even his unique stunt "Yan Hui" didn't rush out. Psychological warfare can be used against novices. Do you think Kojiro is a novice? As the founder of Yan Liu School, Kojiro naturally does not need to question, and Musashi is not a villain. One is the blade master, and the other is Hao Jian. After the First World War, it was not Liuyan Island, a household name, but Musashi Miyamoto and Sasaki Kojiro.
