After taking over the snake uncle's foundation, Sasuke came to surrender on his own initiative.

"But Sasuke can use Fire Style in addition to Lightning Style..."

"That's because Sasuke possesses both fire and lightning attribute chakras, and his ability to control chakras is much stronger than yours." Kakashi shook his head helplessly.

Naruto clenched his fists, his eyes full of fighting spirit, "One day I will surpass him!"

Sasuke snorted, "You? You better learn how to use wind jutsu correctly first."

At this time, Teacher Iruka came over and said, "Everyone, stop arguing. The Ninja School has decided to hold a special combat exercise. The rules of this exercise are very special. You must work in pairs and cooperate with each other to win."

Naruto's eyes lit up and he looked at Sasuke, "Hey, Sasuke, how about we work together again? Prove to everyone that we are the strongest team!"

Sasuke hesitated, a trace of disdain on his face, "Humph, since this is a little interesting, I will reluctantly cooperate with you this time. But if you drag your feet, don't blame me for being rude."

Naruto grinned and said, "Don't worry, I won't lose to you!"

"Okay, Naruto, just focus on your training. Sasuke, keep an eye on him and don't let him slack off." After saying that, Kakashi led Sakura to the other side of the woods.

"Sakura, do you know what is the most important thing for a medical ninja?" Kakashi stopped and asked. Sakura thought carefully and answered: "Strong healing ability and judgment of various injuries?" Kakashi shook his head, "It is to accurately judge the situation on the battlefield and protect yourself. Once a medical ninja is captured or killed, it will be a huge blow to the entire team." Sakura nodded in sudden enlightenment.

"So, I'm going to teach you some simple but effective defensive techniques. These are specially designed for medical ninjas in dangerous situations. They can resist attacks in a short period of time and give them a chance to escape." Kakashi said as he demonstrated the moves. Sakura watched intently and imitated them. In the distance, Naruto secretly glanced at this side and muttered in a low voice: "Teacher Kakashi must be teaching Sakura super powerful ninjutsu. It's really unfair." Sasuke looked indifferent and just practiced silently.

Kakashi watched Sakura repeat the movements skillfully, and felt relieved. At this moment, he suddenly looked up at the sky and said thoughtfully: "In fact, whether it is revenge or the pursuit of love, you still lack sufficient strength." Sakura stopped her movements and said firmly: "I know, Kakashi teacher, so I have to keep getting stronger."

At this moment, there was a sudden commotion in the distance. Kakashi's face changed, "Not good, there may be an enemy attack." Sakura became nervous and unconsciously clenched her kunai. Kakashi quickly made arrangements, "Sakura, go meet up with Naruto and Sasuke first, I'll go check the situation. Remember, if you encounter danger, prioritize your own safety." Sakura nodded and ran in the direction of Naruto and the others.

When she found Naruto and Sasuke, she found that they were ready for battle. Naruto said excitedly: "Sakura, you are just in time, let's fight back the enemy together!" Sasuke calmly analyzed the movements around him. As the enemy gradually approached, the four stood together, their eyes full of determination, ready to meet the upcoming challenge.

The enemy finally appeared in front of them. It turned out to be a group of rebel ninjas. They held weapons in their hands, with greed and ferocity in their eyes. The leader of the rebel ninjas laughed loudly and said, "Little devils of Konoha Village, today is the day you die."

Kakashi arrived in time and stood in front of the four people. "You are not qualified yet." After saying that, he rushed towards the group of rebel ninjas. Naruto was not to be outdone, and shouted "Multiple Shadow Clone Technique", and many clones appeared instantly and rushed towards the enemy. Sasuke opened his Sharingan and shuttled between the rebel ninjas at an extremely fast speed, and the sword in his hand drew a series of cold lights.

Sakura took a deep breath and followed the defense techniques Kakashi had taught her to protect her teammates at the critical moment. However, the rebels were numerous and gradually surrounded them. Just when everyone was struggling, a figure flashed and it turned out to be the Fifth Hokage Tsunade. It turned out that Kakashi had sent out a distress signal on his way.

Tsunade's powerful strength quickly turned the tide of the battle, and the rebel ninjas fell one after another. After the battle, Kakashi looked at the children and said, "This experience is also a kind of growth. You understand the power of teamwork." Sakura smiled and responded, "Yes, Kakashi-sensei, we will become stronger." Everyone smiled at each other and returned to the village with a lot of gains.

Sakura clenched her fists and vowed to change this situation. After returning to the village, Sakura began to study hard a method that could quickly enter the battlefield and perform medical ninjutsu. She read a lot of ancient books and even asked Tsunade for advice.

Tsunade looked at Sakura who was serious, and felt relieved. She decided to teach her a modified version of the forbidden technique - the instant medical technique. This is a technique that combines the instant medical technique with medical ninjutsu, which can quickly reach the injured and treat them.

Sakura practiced day and night, and suffered a lot during the period, and failed countless times. But she always gritted her teeth and persisted. Finally, in a simulated combat training, Sasuke and Naruto were in a tough battle again. Just when Sasuke was injured and was about to be hit by the enemy, Sakura performed the instant medical technique. She appeared in front of Sasuke in a flash, healed his wounds instantly, and used her strange power to knock the enemy away.

Naruto cheered in surprise: "Sakura, you are awesome!" Sasuke nodded slightly in approval. Sakura looked at her friends and smiled confidently. At this moment, she knew that she had finally broken through the limitation of medical ninjas who could only provide logistical support.

Kakashi looked at Sakura's determined eyes and a smile of approval appeared on his face. "Very good, Sakura, since you are so determined, come to me every morning starting tomorrow."

The next morning, Sakura arrived at the training ground early, and Kakashi was already waiting there. Kakashi began to test Sakura's current basic abilities, and found that although she had made great progress in medical ninjutsu, she was indeed weak in combat. Therefore, Kakashi developed a special training plan for her situation.

The training was tough, not only with high-intensity physical training, but also with defensive training to deal with various complex attacks. But Sakura gritted her teeth and persevered every time. As time went by, Sakura gradually mastered some unique fighting skills.

One day, the village was invaded by a mysterious enemy. Sasuke, Naruto and other ninjas joined the battle. Sakura also volunteered to join the battle. On the battlefield, Sakura flexibly applied what she had learned. She dodged the enemy's attacks with agility, released medical ninjutsu at the right time to rescue the wounded, and fought back with the newly learned fighting skills when encountering a strong enemy. In the end, with everyone's joint efforts, they successfully repelled the enemy.

Sakura stood on the battlefield, looking at her companions, she knew that she had truly become an excellent ninja who could both save the dying and the wounded and fight side by side.
