At the beginning, he saved the second generation Hokage

After three hours, everyone was exhausted, but they finally completed Yunfei's task, which also gave the classmates a clear understanding of this devil teacher. They finally made it to the end of the school, which made all the students breathe a sigh of relief.

At this time, Yunfei led Kushina to the front of Shengshu. Shengshu looked at Yunfei in front of him and swallowed his saliva. He didn't know what Yunfei wanted to do. At this time, he suddenly heard Yunfei say:

"Am I that scary? Don’t you think that even though you are exhausted today, your strength has improved to a certain extent?"

After hearing Yun Fei's words, Sheng Shu felt the changes in his body. Although the changes were not big, it was obvious that there were still some changes, which surprised Sheng Shu. Before, they all thought that this was the new teacher who tortured himself deliberately, but they didn't expect that this would really work.

Looking at Sheng Shu's expression, Yun Fei shook his head. Did he really think that he was the kind of person who enjoyed torturing others? Seeing that Sheng Shu already had some strength, he said to Sheng Shu:

"Get up quickly, your sister is waiting for us to go back for dinner."

Hearing this, Shengshu felt a little strange. He didn't know when these two people came to his house. Shengshu asked curiously,"Are you going to my house too?"

Yunfei and Kushina were speechless when they heard Shengshu's words. How many days have they been here? Shengshu didn't even notice that there were a few more people in his house? How careless is he?

Seeing that Shengshu didn't want to get up for a long time, Yunfei didn't care. He picked up Kushina with his left hand, grabbed Shengshu's collar with his right hand and went home directly. Along the way, he heard the sound of Shengshu howling like ghosts. Curious residents of Konoha thought it was haunted and went to the streets to see.

After finally returning home, Tsunade, who came out of the house, looked at Shengshu's sloppy appearance curiously. Thinking that Shengshu went out to make trouble, she said to Shengshu angrily,"Senju Shengshu, where did you go to make trouble today? If anyone comes to complain to me again, I will teach you a lesson."

When Sheng Shu heard what Tsunade said, he said aggrievedly:"Sister, am I your biological brother after all? A devil teacher came to our class today and tortured us terribly. You have to take charge of me!"

Hearing what Sheng Shu said, Tsunade glanced at Yun Fei behind him. Tsunade knew that today was Yun Fei's first day as a teacher, and he was actually complained by his own brother on the first day. She looked at Yun Fei with some amusement and waited for him to explain.

"You know that the situation among the major countries has been a little tense recently, right?"

Yun Fei did not explain, but talked about the situation between the major countries. Hearing this, Tsunade nodded seriously, and Yun Fei continued

"If the usual teaching method of Konoha is used, even if these students can go to the battlefield, only a few will survive, and most of them will become cannon fodder....."

Although the rest of the words were not said, Tsunade completely understood what Yunfei wanted to express. She nodded to show her agreement with Yunfei's idea. However, Shengshu on the side was confused and asked,"Sister, teacher, what are you talking about? I don't understand at all?"

Before Tsunade could speak, Yunfei went over and punched Shengshu on the head and said,"Don't call me teacher at home. Call me brother-in-law, okay?"

Hearing Yunfei say this, Shengshu looked at his sister in fear. You know, if someone dared to say that, his sister would definitely make that person pay. A beating would be the lightest punishment. But after waiting for a while, Shengshu found that his sister didn't say anything at all, which meant she agreed. This discovery surprised Shengshu. Finally, someone could control this violent sister. Shengshu immediately hugged Yunfei's thigh and shouted,

"Brother-in-law, my future happy life depends on you."

Tsunade was furious when she heard this. What Rope Tree meant was that she didn't take good care of him before. Tsunade was so angry that she shouted at Rope Tree:"Senju Rope Tree, I see that you are itchy again because you haven't been spanked recently. It's time for you to experience the fun you had before."

After that, she was about to teach Rope Tree a lesson, but Rope Tree, who was smart, hid behind Yunfei and shouted to Yunfei:"Brother-in-law, save me!"

Looking at the two siblings playing tricks, Yunfei said to them with some amusement:"Aren't you hungry? Eat quickly, otherwise you will be cold. There will probably be a good show tomorrow. Tsunade, if you have time, you can go and see it. It should be very interesting."

Hearing Yunfei say that there will be something interesting tomorrow, he immediately showed a curious look. Shengshu knew what would happen tomorrow. Some classmates in the class went to complain to their parents today. I believe that those parents who protect their children will definitely come to trouble Yunfei tomorrow.

Tsunade couldn't help her curiosity and asked Yunfei about it during dinner. Yunfei also told Tsunade what happened at school today. After listening, Tsunade immediately lost interest. You know, Tsunade knows Yunfei's strength. She doesn't think those parents can beat Yunfei.
