After traveling through time, I became friends with Tsunade

"Fight! I still have a ninjutsu that needs to be tested." Yusuke said seriously.

"Just go ahead." Tsunade assumed a fighting stance and shouted at Yusuke.

"First door, open the door, open it."

Yusuke felt the air flow around him gradually rising, his brain became unusually clear, and his body was filled with explosive power.

"I'm coming, Tsunade!" Before he finished speaking, Yusuke disappeared from her sight to Tsunade's astonishment. Tsunade turned around cautiously, only to see a gust of fist wind whistling towards her head. If Yusuke hadn't stopped in time, she would have been hit hard by the punch.

"Ha, ha! Interesting!" Tsunade smiled softly, first grasped Yusuke's fist, then changed the fist into a palm, and directly used a strange force to hit Yusuke's fist.

"Are you looking down on me?" Yusuke disappeared again the moment his fists touched. The next second, Tsunade punched in another direction.

boom!

The surrounding vegetation was swaying in the wind, and Tsunade's fist hit Yusuke's fist, and the two fists collided. Yusuke, who was at a disadvantage, instantly increased his strength, but was still knocked away by Tsunade's strange power.

"It hurts." Yusuke stood up, covering his injured arm. Although he was protected by a thin wire, he was still injured by the shock wave from the collision of the two fists.

"In terms of taijutsu, you're still far behind." Tsunade looked at Yusuke with contempt.

"Ha!" Yusuke clenched his fists.

"Second door, close the door and open it."

"The third gate, the gate of life, open."

Yusuke opened two doors in succession, and his body was surrounded by the rising air pressure turbulence, and his skin turned slightly red. He raised his hand and felt it, and the wound on his hand had healed.

"Next..."

Tsunade was surprised to see Yusuke disappear again. With her strong fighting instinct, she punched in the direction where Yusuke might appear in the next second. However, just when her fist was about to touch, Yusuke changed direction instantly.

After doing this twice, Yusuke punched Tsunade in the stomach hard, knocking her out.

"Painful kick." Tsunade rolled a few times and stood up quickly, sending a wave of attacks towards the ground. In an instant, rocks were rolled up in the air, limiting Yusuke's attack.

Yusuke immediately changed direction upon seeing this, jumped into the sky, and then shot several thin lines to the ground, pulling them with great force. Under the reaction of the force, Yusuke increased his speed again and used a flying kick towards Tsunade.

Tsunade dodged sideways, and then immediately counterattacked, hitting Yusuke with several consecutive punches. Yusuke was beaten back step by step, but he did not panic, and continued to use various moves to fight against Tsunade.

The two sides fought back and forth, neither giving in. Tsunade's strange strength was extremely powerful, and each punch contained great power; while Yusuke relied on his flexible body and line escape ability to escape danger time and time again.

The battle became more intense, and the air around them seemed to be torn apart. Yusuke took the opportunity to open the "Shangmen" and "Doumen", and his speed and strength were further improved. He shuttled between Tsunade's attacks like a ghost, making Tsunade exhausted.

Seeing that the situation was not good, Tsunade quickly used her ultimate move - "Hundred Healings Technique". Chakra surged throughout her body, her skin turned red, and her strength and speed were greatly enhanced.

Yusuke felt Tsunade's powerful aura, but he did not back down.

He concentrated his energy and prepared to use Li Lianhua...

However, Yusuke's muscles were already overloaded, and halfway through the attack, he suddenly half-knelt down.

Tsunade took the opportunity to escape from his attack, and after discovering this, she hurried forward to check.

"You kid, your muscles are overloaded. You are over-consuming your physical energy!" Tsunade was treating Yusuke's injuries with a worried look on her face. When she saw Yusuke's smiling expression, she said unhappily.

"I didn't think too much about it. Today is also my first time using this ninjutsu. It's just that I can have such a fierce battle with you, I really don't want to admit defeat."

Yusuke hadn't expected Tsunade to be so worried about him, so he spoke to her a little sheepishly.

"Don't you still have a bloodline limit? Why do you rely solely on physical skills to fight?"

During the battle just now, Tsunade had already discovered that Yusuke had never used line escape on her, and any he used was just armor covering the surface of his body.

"Why, are you afraid that you can't control yourself and hurt me?"

Seeing Yusuke's sure expression, Tsunade was furious, "We are going to start fighting the enemy tomorrow, and you dare to use such a move that is harmful to yourself. Are you going to do this recklessly?"

Tsunade's tone was both concerned and reproachful. She was dissatisfied with Yusuke's adventurous behavior, but at the same time she admired his persistence and his spirit of not giving up.

Yusuke realized that his actions had made Tsunade worried, and a sense of guilt welled up in his heart.

"I understand. I'll pay attention next time." Yusuke's voice was apologetic.

When Tsunade heard this, her eyes widened.

"There will be a next time? I warn you, you can only use this move to escape when you encounter a strong enemy, understand?"

Yusuke nodded, he understood that Tsunade's words were out of concern for him. This battle made him realize his own shortcomings, and he also understood the importance of protecting himself in battle.

"Go back to the medical department and rest. Your body still needs to go through a comprehensive and systematic examination."

Today was probably an extremely memorable day for the ninjas in the camp. The lord Yusuke, whom they admired so much, was carried back to the camp twice in one day by the equally powerful lord Tsunade.

"Tsunade, I feel too embarrassed to face anyone." Yusuke covered his face and said to Tsunade who was running.

"It's all because of you!" Tsunade replied unhappily.

She herself felt a little embarrassed, but in order to allow the boy to receive treatment as soon as possible, she didn't care about these "face" issues. At the same time, she felt her cheeks begin to heat up.

Arriving at the medical department, Tsunade threw Yusuke onto the bed without any courtesy and fiercely ordered her subordinates: "Check this guy carefully from head to toe, and strip him naked if necessary."

"Yamete..."
