Raikage's Early Years
Ai had outstanding abilities since childhood, and grew up under the strict education and care of the Sandaime Raikage, and the rule that every Raikage must have a partner in the Cloud Hidden Village, after Ai became the Raikage's alternate, the Sandaime Raikage recruited a large number of new-generation ninja, and there was only one of them that could inherit the name of "Bee," who could assist Raikage to maximize his performance, and who would be a great help to Raikage. The only one of them who can inherit the name of "Bi" is the one who can assist Raikage to maximize his performance, and at the same time, he also has to act as Raikage's guard, which is the heavy responsibility of "Bi".
During this time, Toudai, as the examiner of the "Jedi Ox Thunder Plow Hot Knife" ability test, was responsible for testing their coordination with Ai, requiring them to use the Jedi Ox Thunder Plow Hot Knife with Ai to break the neck of the rubber doll, and they had to apply the same amount of force from the left and right side at the same time in order to be successful, but there were very few successes, and the Sandaime Raikage and Toudai were expecting it, but were greatly disappointed. Tsuchidai were looking forward to it but were disappointed.
