"Wood Release: Thorn Kill Technique!"
Nawaki formed hand seals at great speed, then slammed a single hand onto the ground. Moments later, Tsunade, who was standing ten meters away, noticed numerous tree roots sprouting leaves and vines bursting from beneath her feet to entangle and bind her tightly.
Seeing this scene, Karn, who was watching the battle from the sidelines, brightened his eyes. Such alternative bondage really did have miraculous effects on Tsunade.
Tsunade happened to notice Karn's gaze. She had originally wanted Nawaki to showcase the power of Wood Release Ninjutsu in order to pique Karn's interest, but this foolish younger brother had actually achieved the exact opposite result.
"Idiot Nawaki!"
Furious in her heart, Tsunade broke free from Nawaki's only Wood Release Ninjutsu with sheer brute strength, then used the Body Flicker Technique to appear behind Nawaki and slammed her fist onto his head, immediately causing him to cradle his head in pain.
"Big sister, your strength is too great! Weren't you the one who said you wanted to test the ninjutsu?"
Nawaki clutched the large bump on his head and spoke to Tsunade with great grievance. Could it be that she had simply wanted to beat him up under the guise of testing ninjutsu?
"Ahem, this is a warning to you not to be so careless in the future. You were lucky last time, and you won't have such a miraculous serum to save you every time, idiot Nawaki!"
Tsunade gave a light cough and found an excuse to ruthlessly lecture Nawaki.
Nawaki had slowly gained mastery over the Wood Release Kekkei Genkai. Under Tsunade's rigorous training, he had learned a Wood Release Ninjutsu in just four days, and its power was not weak. Without Tsunade's monstrous strength, ordinary ninjas would probably find it hard to escape.
