The East Japan is a nation skilled in learning by stealth, and they boldly claim what they have learned as their own invention, like the Ninjutsu used by Ninjas, which is actually some of the Five Elements Escape Technique from Huaxia's Cultivation Realm, but was stolen by the people of East Japan and claimed to be their own invention.
Although such behavior of East Japan is disgraceful, they have done a much better job in inheriting these Five Elements Escape Techniques. After all, nowadays on the land of Kyushu, there are few sects using the Five Elements Escape Techniques, but East Japan has well inherited them.
Even though East Japan has no territory in the Cultivation Realm, and their population is very small, the ninja culture has never been interrupted from ancient times to the present, and it continues to be passed down, increasingly becoming a tool of East Japan's ambition for dominance, turning into a powerful weapon of East Japan.
