Ninja bugeicho momochi sandayu (1980)

In an attempt to seize the world, Yuchai Xiuji, in order to clear the way, dispatched confidants who do not know the fire warden (Mayichi Chiba) to encircle and suppress the IGA ninjas. When a hundred people perish, Eagle Maru (Hiroshi Makada), the son of Santai, fled to China. More than a decade later, he learned martial arts and returned to Japan to get together with his childhood friends and vow to take revenge on the Fengchen family. Toyoshi Hideyoshi is in urgent need of financial support for his foreign expansion plan, and the dagger worn by Eagle Maru has a secret map of the family gold mine, so Fengchen once again sent troops to encircle and suppress the crippled party. After several wars, when the Baidi clan was defeated and Eagaru was desperate, the mysterious old man Huze Bai Yunqi (Dan Bo Zelang) helped, trained everyone, and handed the dagger with another half of the map into the hands of Eagaru.
