In Konoha, they wiped out the Sarutobi clan at the start.

"Lord Chiya, what exactly is that chain? How can it suppress chakra?" Yekura asked with a grave expression. He sensed a threat emanating from the chain.

Chiya smiled faintly and explained, "That's the unique ability of the Uzumaki clan, the Adamantine Sealing Chains. When used, multiple chakra chains extend from the back. They can be used not only as powerful offensive weapons but also to create barriers. The power depends on the amount of chakra. With Karin's chakra, let alone Sasuke's mere Heavenly Curse Seal, she could easily suppress even Naruto in his half-tailed beast form."

"That's really an amazing technique," Yekura exclaimed.

"Alright, the show's over, and we've achieved our goal. It's time to go back." Qianye nodded, placed his right hand on Yecang's shoulder, and used the Flying Thunder God Technique to disappear.

Ten days later, Konoha Village.

The Hokage's office.

Those present included Yamato, Naruto, Sakura Haruno, and Karin.

"Lady Tsunade, that's roughly what happened." Yamato nodded and stood at attention, reporting the whole story to Tsunade.

Karin lowered her head slightly, feeling annoyed that she hadn't been able to speak to Chiya.

Naruto and Sakura were equally frustrated, but their frustration stemmed from not being able to bring Sasuke back.

"I never expected things to turn out this way."

After listening to Yamato's report, Tsunade slumped onto her desk, feeling utterly exhausted. How could that guy have gotten involved with Orochimaru again out of nowhere?

Yamato nodded. "Yes, Lady Tsunade. Given the situation at the time, if Fujiwara Chiya had made a move, I'm afraid the irrational Naruto might have been captured by Chiya."

"But judging from the situation at the time, Fujiwara Chiya did not seem to be keen on capturing tailed beasts. Moreover, the Akatsuki specifically sent him to kill Orochimaru."

"Not only did he disobey orders, but he also used this to threaten Orochimaru. Judging from the information that his Wood Release clones gathered at the time, it seems that Fujiwara Chiya threatened Orochimaru in this way more than once, and Orochimaru was helpless in the face of this."

"That one of the legendary Sannin seems to be quite afraid of Chiya. But overall, the Akatsuki organization isn't as united as one might imagine, which is a silver lining in a bad situation."

"Threatening Orochimaru is really in line with that guy's style." Tsunade sighed helplessly, then turned to Sakura, her expression suddenly turning serious. "Sakura, aren't you going to say anything?"

"Lady Tsunade, I'm sorry." Sakura's eyes grew even dimmer. She knew that the main reason for the failure of this mission was herself.

"I'm not blaming you." Tsunade sighed softly and said seriously, "I just hope that we can understand one thing: no matter what, we must put our comrades' lives first."

"Blame her?" Naruto looked at Sakura with a blank expression and asked, puzzled, "What exactly happened?"

Yamato explained from the side, "Sakura has the ability to dispel genjutsu. Even if Sasuke's Sharingan could trap her in a genjutsu, he would never be able to control it freely. So you understand now."

Naruto exclaimed, "Does that mean that Sakura deliberately let Sasuke go?"

Tsunade said, "Alright, that's enough about this. Sakura, go back and rest for a while. Starting tomorrow, report to the medical unit."

"Yes, Lady Tsunade." Sakura replied dejectedly, then turned and walked out of the Hokage's office.

"Why...why do this, Granny Tsunade?" Naruto looked at Tsunade. "Are you going to kick Sakura out of Team 7 just because of this? Sasuke's already gone...if that's the case..."

In that case, the original Class 7 will cease to exist completely.

"No, it's not because of that." Tsunade shook her head.

Standing behind Tsunade, Shizune, worried that Naruto might misunderstand, quickly explained, "Actually, this was already decided when you went to carry out the mission to retrieve the Kazekage."

"Then why do we have to do this?" Naruto asked, puzzled.

"Because if you include me, Team 7 will have two medical ninjas. You must know how important medical ninjas are to a team. Medical ninjas are always a scarce resource. There are many teams that don't even have a medical ninja." Karin was the one who spoke.

"Then why don't you go?" Naruto said without thinking.

However, before Naruto could finish speaking, Karin's fist left a large bump on his head. "Idiot, do you think I want to be with an idiot like you?"

Yamato, still shaken, explained, "Naruto, after this battle with Orochimaru at Tenchi Bridge, you must understand Karin's importance now."

Naruto's pupils suddenly contracted as steam rose from his headband. He recalled the scene of his rampage, and a chill ran down his spine as cold sweat broke out on his forehead.

He then instinctively asked, "So, who's the new member of our Class 7?"

"It's me." A clear voice suddenly rang out, and before everyone could react, there was a bang, the smoke dissipated, and Chika appeared on the Hokage's office desk with her arms crossed.

"Chinatsu?" Everyone's eyes widened in disbelief, especially Naruto. Because he was under a genjutsu and hadn't witnessed Chinatsu fighting Itachi Uchiha, he was speechless, pointing at Chinatsu, "Grandma Tsunade, are you kidding me? It's such a brat!"

"Chinatsu is no ordinary brat, she's very strong," Tsunade said with a smile.

Upon hearing this, Yamato, the acting captain of Team 7, felt a pang of sorrow and hesitated before saying, "Hokage-sama, I've heard Kakashi-senpai mention Chinatsu's outstanding performance during the Kazekage recapture mission. But we'll be facing powerful Akatsuki members in the future, and Chinatsu is still so young. Will she be able to..."

"It's precisely because we'll be facing Akatsuki in the future that I'm bringing Chinatsu into Team 7. Naruto." Tsunade said sternly to Naruto.

"Here." Naruto stood at attention.

Tsunade said solemnly, "After this battle with Sasuke, you should know the gap between us now."

"Yes." Naruto swallowed hard, his heart filled with resentment.

Tsunade continued, "So from today onwards, you will train with Chinatsu and try to improve the Rasengan, turning it into your own ninjutsu."

"Have Chinatsu instruct me?" Naruto was taken aback. "Um... Granny Tsunade, are you sure you don't mean Kakashi-sensei?"

"Of course. Chika is very strong. She's truly proficient in all five elemental ninjutsu." Tsunade nodded, a mysterious smile on her face. "However, considering the possibility of the Nine-Tails' chakra within you going out of control, I'll have Yamato and Karin keep an eye on things. Kakashi will also be there to help you. It's up to you now."

While they were talking, Chika actually conjured a small spiral shuriken in front of everyone.
