This is also why Qin Fang said that the key was what Hattori Hisanari wanted because the treasury was on Hattori Hisanari's side. As long as you had the key, you could open the treasure repository...
This made Kawada Musashi feel deeply angry. This treasure repository was the accumulation of the Musashi School for hundreds of years. It had finally fallen into his hands, and before it could even warm up, it could be wiped out by the Iga School. How could he easily accept this?
Moreover, many disciples of the Musashi School were killed, and even his only son, Kawada Masami, did not escape the murder, which made him furious and led to the current situation.
Of course, all of this was directed by Qin Fang. Although the development of things deviated slightly from Qin Fang's initial plan, there was not much change in the overall direction.
