Uchiha Ryun saw Nawaki walking over. He smiled slightly, patted Nawaki's head, then turned to look at Tsunade.
Tsunade was puzzled, but at that moment, Uchiha Ryun explained the reason to her.
"Experimentation is the only standard for testing the truth. Since Tsuna doesn't believe it, then try it yourself." Uchiha Ryun's confident smile, paired with his looks, seemed very convincing!
Tsunade thought for a moment and nodded. "Indeed, we should test it." If it really worked, then Nawaki would have some protection when going to the battlefield!
"Test? How? Have Sis hit this outfit?" Nawaki scratched his head. At that moment, Uchiha Ryun's lips curled up, then turned serious.
"Nawaki, let me ask you, do you want to go to the frontlines to train and fight?" Seeing Uchiha Ryun's expression, Nawaki also became serious.
"Yes, Ryun-nii, I want to go!" Looking at Nawaki's determined face, Uchiha Ryun felt a little guilty in his heart. Tricking this naive kid made his conscience sting a bit.
But it only lasted for a moment. Uchiha Ryun said, "Then, Nawaki, put on this outfit. Later, your sis will test its defensive power! Only if the defense is strong enough will your sis agree to let you go to the battlefield!"
After saying this, Uchiha Ryun patted Nawaki's shoulder.
"Okay!" Nawaki was about to put it on when he suddenly froze. Wait, test the defensive power? Have Sis hit him? Recalling all the times his sis had beaten him up since childhood, his face instantly turned pale.
Uchiha Ryun naturally noticed this. His eyes flickered—looks like he needed to push further!
"Nawaki, you know your sis's personality. If she can't guarantee your safety, she definitely won't sit back and let you go to the frontlines!" Uchiha Ryun smiled and glanced at Tsunade.
"Right, Tsuna?" He even asked, since his conversation with Nawaki wasn't hidden from Tsunade, who could hear everything.
Tsunade nodded. "That's right, Nawaki. Nothing is more important than your safety! If we can't ensure your safety, I will never agree to you going to the frontlines, no matter what!"
Hearing Uchiha Ryun and Tsunade's words, Nawaki took a deep breath and looked at Tsunade. "I understand, Sis!"
With that, he took the bulletproof vest from Uchiha Ryun and put it on directly. Uchiha Ryun nodded at Tsunade, then jumped back, putting distance between himself and Nawaki.
Tsunade had inherited Hashirama's monstrous strength. Even though she was only at the jonin level, her punches could reach near-Kage-level power.
If he got hit by one of those punches while standing nearby—yikes!
Uchiha Ryun shook his head and stopped thinking about it. Otherwise, he might not be able to sleep at night.
Nawaki watched as Uchiha Ryun moved away and his sis stood there seriously. He couldn't help but gulp.
"I'm coming! Brat, get ready!" With that, Tsunade stepped forward with her right foot, cracking the ground of the Senju clan's estate. Then, she shot toward Nawaki like a streak of light.
Nawaki also had talent in monstrous strength, but since he was six years younger than his sis, his strength was nothing compared to hers!
"Monstrous Strength, Mountain-Crushing Strike!" Tsunade appeared in front of Nawaki. Her right arm pulled back, her waist twisted, and then she threw a punch.
Boom! The punch landed on Nawaki's bulletproof vest with a loud noise. Nawaki was sent flying, only stopping after smashing into a wall.
His body was embedded three inches into the wall. And this was with Tsunade holding back, using only chunin-level strength.
"Nawaki!" Tsunade called out. Nawaki quickly responded, "Sis, I'm fine! I'm not hurt at all!"
Hearing Nawaki's energetic reply, Tsunade sighed in relief. Nawaki struggled free and jumped out of the wall.
Tsunade had felt something strange earlier—before her fist even touched Nawaki, a faint yellow light barrier appeared. Her punch had landed on the barrier, sending Nawaki flying.
Nawaki had the clearest experience of this. Indeed, a pale yellow light barrier had appeared. If you didn't look closely, you wouldn't notice it. His sis's punch hadn't actually hit him—it had struck the barrier.
Inside the barrier, he hadn't been hurt at all. He grinned, realizing that all of this was thanks to the bulletproof vest!
"Sis!" Before he could share his realization, Tsunade instantly flashed in front of him, her expression icy. "Heavenly Kick of Pain!" This was the most brutal move in her taijutsu arsenal.
Even though she was a jonin, combining monstrous strength with this kick could reach elite jonin level!
Boom! With a loud noise, Tsunade's kick sent Nawaki crashing into the ground. She carefully assessed the situation—what she had kicked wasn't flesh, but a soft membrane. The membrane had completely dissipated her force before disappearing, letting her foot land on Nawaki's chest.
This strike was already close to Kage-level, yet the membrane had still blocked it without showing any signs of breaking.
Tsunade was now excited. With this piece of equipment, as long as Nawaki didn't run into a Kage on the battlefield, he would basically be safe!
Tsunade turned and looked at Ryun on the other side, then pounced toward him!
Uchiha Ryun wasn't paying attention and was immediately tackled to the ground by Tsunade.
"Thank you, thank you, Ryun. With this equipment, Nawaki can stay safe!" Tsunade's heart was filled with gratitude.
Uchiha Ryun froze for a moment, feeling the soft sensation against his chest. He took a sharp breath—if Tsunade didn't get up soon, his little brother would rise to the occasion!
So, Uchiha Ryun gently patted Tsunade's head and said softly, "Get up, Nawaki's still watching."
Hearing this, Tsunade quickly stood up and looked at Nawaki. Nawaki trembled under her gaze and immediately looked up at the sky. "The sky is so... sky-like today!"
He didn't even know what he was saying, but he was now certain—Uchiha Ryun would be his future brother-in-law!
Tsunade snorted, then turned back, blushing shyly at Uchiha Ryun. "Ryun, it's all my fault. I didn't control my strength earlier and accidentally pushed you down..."
Feeling like this wasn't very ladylike, she quickly shut her mouth, her face turning red.
But Uchiha Ryun was intrigued. He smirked and leaned closer to Tsunade's face. "It's fine. It was soft—I mean, comfortable."
After saying that, he turned and ran without looking back.
Tsunade was stunned for a moment, then chuckled helplessly. She turned to Nawaki. "Brat, now I can rest easy letting you go to the frontlines. But remember to listen to your sensei, Orochimaru!"
"That guy isn't just the strongest among the three of us—his escape skills are also something Jiraiya and I can't match. Learn as much as you can from him." After saying this, Tsunade headed inside. She needed to tell her grandmother this news!
