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

Ring ring, ring ring—

As the bell rang to signal the end of get out of class, they stood outside the door all morning. When it was lunchtime, everyone took out their lunchboxes.

Lin Chuan returned to his seat, took out his lunchbox, which was lunch prepared by his mother: several rice balls, two fried eggs, a grilled sausage, and some ketchup.

He sat on his desk, opened his lunchbox, and saw Naruto and the others gathered around. He then showed his lunch to everyone.

"Lin Chuan, you have grilled sausages. I'll trade you some meatballs," Choji sniffed, moved closer to Lin Chuan's table, and drooled over the grilled sausages in Lin Chuan's lunchbox.

"Okay, I'll have two meatballs," Lin Chuan said with a smile, picking up a grilled sausage with his chopsticks while waiting for Choji's meatballs. He suddenly noticed Naruto's dejected mood, guessing that he had forgotten to bring instant noodles again.

"Naruto, I asked Mom to prepare an extra bento box. This one is for you..."

Besides fighting, another way to build a friendship with Prince Naruto is to eat together. How could he possibly forget the opportunity to gain his favor? He had to seize it so he could take advantage of him later.

Therefore, he also asked his mother to prepare an extra lunchbox, in case Naruto couldn't eat it and got hungry during training, he could eat it himself.

"Really?" Naruto clutched his rumbling stomach, looking at the fragrant bento boxes in front of everyone, and couldn't help but swallow.

"Here you go," Lin Chuan tossed the lunchbox to Naruto, otherwise his drool would have spilled onto his desk. Both lunchboxes contained the same food, and each had a grilled sausage inside.

"So delicious!" Naruto had never tasted such a delicious bento box and ketchup before. After all, he usually ate instant noodles or went fishing in the wild, picking mushrooms that he couldn't tell if they were poisonous, and then making a big stew.

This lunch was indeed a rare treat for Naruto...

"Lin Chuan, thank you for lunch. I'll bring you money for lunch tomorrow," Naruto said, putting down his lunchbox, wiping his mouth with satisfaction, and checking his pockets to find that he hadn't brought any money with him today.

"Okay," Lin Chuan thought for a moment. He remembered that a bowl of Ichiraku Ramen cost sixty ryo. In the Naruto world, one ryo was equivalent to ten yen, so a bowl of Ichiraku Ramen would cost six hundred yen, which is thirty yuan in RMB.

Since he was going to cook lunch anyway, and he could earn some extra money so his mother wouldn't work for nothing, he suggested to Naruto, "Naruto, how about we take care of all your lunches from now on? We'll cook the same amount as today, eighty taels per serving, thirty servings a month, that's two thousand four hundred taels..."

"Two thousand four hundred taels? The old man didn't give me that much for living expenses," Naruto said, somewhat perplexed upon hearing the number.

Sarutobi Old Deng would give him a small amount of living expenses every time he came over; otherwise, he wouldn't go fishing by the river and picking wild mushrooms to make soup.

"Why don't you ask that old man to give you more money? Just say you're growing and need to eat more," Lin Chuan said helplessly, pouting. Sarutobi was just taking advantage of Naruto's lack of math skills; he knew exactly how much legacy the Fourth Hokage had left behind.

He knew Naruto before he started school and knew who the old man Naruto was talking about was, but he didn't dare to have too much contact with Naruto back then, since he hadn't started school yet. Now that they were classmates, he could openly approach Naruto.

Sarutobi probably gave Naruto a small allowance because he was afraid Naruto would squander the money or that someone would steal it. But with the Anbu watching Naruto every day, who would dare to steal Naruto's allowance? They'd be asking for trouble.

"Okay, it's settled then," Naruto thought for a moment and agreed. He figured he could just ask the old man for more living expenses next time, since only Lin Chuan was willing to bring him lunch.

After lunch, the afternoon physical education class began, where the newly enrolled children exercised their bodies and learned to handle kunai, practice throwing them, and so on.

"Class, today's PE class involves running three laps around the track and practicing kunai throwing. There will be a kunai throwing test next week," Iruka announced as he spoke about the PE class, completely unaware that several little ones had already quietly slipped away.

Lin Chuan wasn't interested in physical education class. He had already been exposed to kunai throwing and even the intensity of running, which was far beyond what these children could compare to.

After climbing over the school wall, he arrived at the deserted training ground outside. Only the spacious outdoor area was convenient for him to practice throwing kunai.

He had just tricked Naruto out of his lunch money. A lunch cost eighty taels, and he could keep forty taels for himself, since cooking at home didn't cost much.

In this way, one could earn 1,200 taels a month, and with two semesters and eight months a year, that would amount to 9,600 taels. Over six years, that would be nearly 60,000 taels.

With 60,000 taels of cash, he could purchase some equipment needed for training, as well as training ointments and other supplies. He could also freely learn ninjutsu and train his body to prepare for his next plan.

Little did he know, his truancy had been discovered by a few underlings...

……

"Lin Chuan? He skipped class on the first day?" Naruto and his two friends hung behind Lin Chuan, watching him arrive at a training ground, put down his schoolbag, take out a kunai, and throw it at the heart-shaped wooden stake.

Shikamaru and Choji were also surprised by Lin Chuan's truancy. They didn't know each other before, but on the first day of school, they got into a fight and the four of them stood outside the classroom and talked for a long time.

After getting to know each other for a morning, they were all eating Choji's snacks and had a good understanding of each other. However, Lin Chuan rarely spoke and was refining his chakra by himself.

Now that they saw Lin Chuan skipping class alone again, they were all very curious about him, so they followed him and discovered that Lin Chuan seemed to be a cultivation fanatic.

Tap tap tap, tap tap tap—

The three of them stared at the kunai in Lin Chuan's hand, which hit the bullseye every time. Choji and Naruto almost cried out in surprise, but Shikamaru quickly covered their mouths.

A foodie and an orphan might not understand the significance of hitting the bullseye every time, but Shikamaru has been very smart since childhood, and with his father being the Hokage's advisor, he knows a lot.

He knew very well how hard someone his age could hit the bullseye with their kunai every time, and how much time they had spent to achieve that, because he was one of them.

If it weren't for his father forcing him to practice shuriken, his kunai throwing wouldn't be so accurate. If it were Lin Chuan, he would either have a strict father or the other person would understand the importance of hard work.

Lin Chuan was still practicing kunai throwing, unaware that the clever Shikamaru had already guessed most of it. Every day, he had to practice throwing kunai at a fixed target two hundred times and throwing kunai at a moving target one hundred times, which was one of his daily training tasks.

Besides kunai throwing training, there were naturally other training methods. After throwing kunai two hundred times, he tied wood to a tree trunk and began practicing throwing kunai at a moving target one hundred times.

After throwing over a hundred kunai, I checked my hit rate for the day and found that I hit the bullseye 288 times, compared to 198 times on the fixed target. I need to keep up the good work!

He had to be able to hit the bullseye 100% of the time before he could be considered a beginner in kunai throwing. After recording his hit rate for the day in his notebook, he rested for half an hour and drank some water.

Next, he would jog five kilometers around the training ground with weights. His daily running requirement was ten kilometers, five kilometers here, and then another five kilometers after dinner at home.

He was unaware that the three little ones who had run away with him had secretly returned to school...
