However, the Yang Nin are different. They are similar to samurai, openly using their strength to defeat others.
Ling Zhenfei had encountered several attacks from Japanese ninjas before in Huaxia, and they were mostly sent by Watanabe Nagayumi, mostly Yin Nin.
After arriving here, Ling Zhenfei was quite puzzled. How come the Watanabe Family, known for Yang Nin, sent Yin Nin to Huaxia to assassinate him? At this moment, Ling Zhenfei had an understanding.
Kai is also a ninja school, originally active in the Kai region, so now there are Kai branches in Bin Qi Wu, and Watanabe Kazushi from the Iga-ryu always wanted to ally with the Kai Family through marriage.
This would strengthen their power; the Kai Family is a legitimate Yin Nin, extremely powerful.
Ling Zhenfei estimated that the previous assassination attempt by Yin Nin in Huaxia was a result of the negotiations between Watanabe Kazushi and the Kai Family.
