Naruto: I start with one door, and I can open it infinitely.

Naruto and his two friends quietly returned to the school playground, just in time for Iruka's roll call.

After taking attendance, Iruka realized that his class was missing a student. This was a big deal. How was he going to explain to the student's parents that his class was missing a student after school?

When asked, none of the classmates had seen where Lin Chuan had gone. Even the three Naruto kids, who knew where Lin Chuan had gone, pretended not to know under Shikamaru's strict insistence.

After all, selling Lin Chuan now would be an offensive move. When Shikamaru told Naruto and Choji about it, they both shut up.

Iruka couldn't find Lin Chuan, so he could only wait until school was over. After all the children in his class were picked up, but Lin Chuan's parents were nowhere to be seen, he had no choice but to set off for Lin Chuan's house, hoping that Lin Chuan would come home on his own.

Otherwise, my career as a homeroom teacher, which had just begun, would have to end because of the loss of a child.

Lin Chuan's house is located to the left of the Hokage Rock in Konoha, on the edge of the village. There is a river and some rice paddies nearby, and many wooden houses are situated there, one of which is Lin Chuan's house.

"Who are you?" Lin Chuan's mother opened the wooden door and saw Iruka wearing a green ninja vest, and asked in confusion.

"Are you Chiba Rinchuan's parent? I'm Rinchuan's homeroom teacher, Iruka," Iruka introduced herself first, then peeked into the house, still not seeing Rinchuan, and could only explain, "Rinchuan got into a fight with a classmate this morning, and I told him to call his parents after school, but he skipped class again this afternoon, so I came to see if he had gone home..."

"What? Fighting and skipping class?" Lin Chuan's mother gasped in surprise. She knew her son was mischievous, but she hadn't expected him to be this naughty. She immediately said softly, "Teacher Iruka, please wait a moment. Lin Chuan has already returned home and is practicing ninjutsu with his father in the backyard. I'll call him over right away..."

"Phew," Iruka breathed a sigh of relief. Seeing that Lin Chuan's mother had left and Lin Chuan was at home, he felt relieved. He really was a problem student.

Iruka seemed to have forgotten something; his focus was on Lin Chuan being at home, not on Lin Chuan actually learning ninjutsu—that child was only six years old!

When Lin Chuan's mother came to the backyard to tell Iruka what he wanted, Lin Chuan's father didn't care or get angry, because Lin Chuan had already told him, and even said that the ninja school courses were too boring.

He discovered that his son was very opinionated and a little genius. He had only demonstrated it once, and Lin Chuan had already learned the Three Body Technique at the age of three. Now at the age of six, he was going to learn ninjutsu. There was really nothing to learn at the ninja school except for playing with a group of peers. It wasn't like he hadn't been to a ninja school before.

"You can still laugh?" Lin Chuan's mother was surprised to see her husband still laughing. Their child was always fighting and skipping classes at school, but all he could do was laugh.

"Don't worry, I'll handle it," Lin Chuan's father said, looking at his son with great satisfaction. If his son could learn ninjutsu now, it wouldn't be long before he couldn't teach such a smart son anymore, and that would be the real headache.

This is the privilege of a little genius. Let alone something as trivial as skipping class, Lin Chuan thought to himself. After he learns ninjutsu, he will use his reputation as a little genius to get close to Naruto. That way, Sarutobi Old Man will not be disgusted and will not issue an order to prohibit contact.

However, the reputation of being a little genius also has a drawback. He hasn't forgotten that there's an old fox in Konoha who loves little geniuses like him. So before the reputation of being a little genius spreads, he needs to take another precaution.

"Xiao Chuan, did you remember the hand seals for the Water Clone and Water Chaos Waves?" Lin Chuan's father led Lin Chuan towards the door, casually inquiring about the ninjutsu instruction: "Ninjutsu requires using hand seals to mobilize and condense the chakra within the body, temporarily storing it between the mouth and chest, and then, after attribute transformation, exhaling it..."

"I've remembered, Dad," Lin Chuan recalled the hand seals for Water Clone and Water Chaos Wave. There were only a few simple seals, all of which were very basic C-rank ninjutsu among the five types of ninjutsu.

But since he had already transmigrated, how could he not learn the cultivation accelerator and the Shadow Clone Technique? He immediately asked, "Dad, do you know the Shadow Clone Technique? I want to learn it..."

"Shadow Clone Technique is a B-rank ninjutsu. You can't use it with your current chakra level. We'll talk about it when you're older," Lin Chuan's father didn't understand Lin Chuan's intention. He had already seen Iruka outside the door.

"Dad, my chakra attribute hasn't been tested yet." Lin Chuan saw that his cheap father wasn't going to teach him, so he had no choice. He could only barely release B-rank ninjutsu at the moment, so it was unrealistic to use it to accelerate his learning. He could only ask about another matter: his chakra attribute hadn't been tested yet.

"There are still some chakra paper left at home. We'll talk about it after dinner," Lin Chuan's father said, already welcoming Iruka into the house. Lin Chuan could only keep quiet and wait until Iruka left before continuing.

"Teacher Iruka," Lin Chuan greeted Teacher Iruka as she entered the house respectfully. After all, she was a responsible and dedicated teacher who had managed to find her way into his home.

"Lin Chuan's parents," Iruka said, sitting down on the tatami mat in the living room and beginning to tell the story of Lin Chuan, the problem student.

"Yes, Teacher Iruka, I understand what you said. I will discipline Xiaochuan strictly," Lin Chuan's father bowed slightly to Teacher Iruka to express his apology, and continued:

"My son Xiaochuan caused trouble for Iruka-sensei at school. If it happens again, Iruka-sensei, please don't worry, Xiaochuan will go home by himself. There's no need for you to come in person. I will discipline Xiaochuan strictly..."

"Hurry up and apologize to the teacher," Lin Chuan's father nudged Lin Chuan, urging him to say a few good words to Teacher Iruka.

"I'm sorry, Iruka-sensei, I won't do it again next time," Lin Chuan said, suppressing a laugh as he bowed his head and apologized to Iruka. He said he wouldn't do it again, but he would still skip class next time. He could just say "I won't do it again" next time.

Seeing that the father and son were very sincere, Iruka didn't say anything more. He didn't know that if Lin Chuan skipped class every day until he became numb to it, he would never visit the home again. As long as he could see Lin Chuan in class the next day, he wouldn't care about anything else.

Another reason Lin Chuan wanted to learn Shadow Clone Technique was that he wanted to create a shadow clone to go to school. Otherwise, he would be too lazy to go to school every day, and it would also affect his ninjutsu practice.

"Teacher Iruka, I will be more careful in disciplining my child next time. Please stay for dinner," Lin Chuan's father said, inviting Iruka to dinner as soon as the matter was resolved and Lin Chuan's mother had prepared the meal.

"No, I have something to take care of at school. Maybe next time," Iruka said. It was his first time visiting Lin Chuan's house, and he felt embarrassed to stay for a meal. He quickly said goodbye to Lin Chuan's father and left the house.
