I suddenly became a yakuza boss.

At first, Komachi nodded vigorously, but gradually her face grew paler and paler, and she became increasingly silent. In the end, when all the answers were calculated, her eyes narrowed into slits, and her body trembled. At her current level, she couldn't even do the second step.

Li Xuan reviewed for another half hour. When he subconsciously looked at Komachi and Kohina again, he saw that Komachi was engrossed in reading an extracurricular magazine, while Kohina had disappeared.

"Sorry, I got sleepier and sleepier watching it, so I'm going to relax a bit..."

With an embarrassed expression, like a kitten, Komachi explained to Li Xuan.

"Little Chu is going to the toilet."

Nitta Hina, holding a comic book from the library, spoke to Li Xuan.

"No, you're too relaxed. If you were a little more tense, you wouldn't dare not continue studying even if you were sleepy when being supervised."

Li Xuan began to lecture Komachi.

Secondly, he used his fist as if he wanted to nail Hina into a wooden board: "When you lie, you have to know when to give up on the comics you haven't finished reading!"

"Why did Gen beat me up when Komachi-senpai slacked off too?"

The little chick hugged her big head, tears welling up in her eyes, and asked, feeling it was very unfair.

"There's no reason why, it's just that you deserve a beating."

Li Xuan clenched his fists and said through gritted teeth.

Sure enough, the relationship between this brother and sister was different from that between her and her brother.

At least her brother never hit her, not even once.

But probably, the relationship between ordinary siblings is like that between Li Xuan and Xiao Chu.

"If you fail the test again next time, you won't get any snacks next month either."

Li Xuan checked on Xiao Chu's review progress and gave her a firm commitment.

"..."

Komachi observes the relationship between the siblings with curiosity, finding it quite intriguing.

However, Komachi also sensed that the first time the sunglasses-wearing senior was very polite to her, the second time his attitude became more formal, and the third time... she might "enjoy" the same treatment as Hina.

How terrifying...

Komachi's fantasies about her sunglasses-wearing senior have somewhat changed, and she's now more motivated to study hard.

The study session will be held again.

I've been reviewing for two and a half hours straight, which is far beyond Komachi's limit.

"Uh...uh..."

Komachi was exhausted, her eyes were blurry, and she took a ten-minute break in the middle. However, this kind of grueling learning session was not enjoyable at all, and there were no surprises.

She felt like she was walking in the desert, constantly craving water (sleep), craving lots of water (sleep)...

Before she knew it, Komachi couldn't keep her eyes open anymore and simply lay down on the table, taking a nap.

But for some reason, she sensed a terrifying aura.

She opened her eyes and saw a college student with shady connections staring intently at her...

"Did you sleep well? What did you dream about?"

Li Xuan asked without a smile on his face.

"...I didn't sleep, I almost did. I just had a dream and then I woke up."

Komachi was genuinely intimidated by this senior colleague. After hesitating for a moment, she managed to give a weak reply.

This older brother is terrifying!

"Komachi, you have absolutely no sense of vigilance. At this rate, you'll never finish reviewing this book, let alone read it a second or third time. You absolutely cannot sleep during the designated time. You need to at least practice this skill properly, preferably with the help of a green tea..."

Li Xuan was nervous and dissatisfied with Komachi's attitude towards studying, and he urged her in a harsh tone.

However, Li Xuan soon realized that his attitude was problematic.

Komachi sat beside him, head bowed, not daring to utter a sound.

"......"

Li Xuan then realized that he and Komachi were not very close.

"Sorry, I might be a little anxious... You should take a break, I'm going to get some fresh air somewhere else."

Li Xuan apologized, stood up, and awkwardly left for a while.

"No, it's okay, big brother..."

Komachi saw through Li Xuan's thoughts and said to him.

However, Li Xuan had already left. He had patiently sat there reviewing for more than two hours without leaving and finally began to rest.

Hina Nitta, sitting to the side, was also observing this scene. Even though she had been scolded and beaten, Gen didn't show the slightest bit of remorse.

After leaving his seat, Li Xuan went to get some fresh air elsewhere.

He then realized where his problem lay. In terms of learning, it seemed that apart from teaching chicks, he had never taught anyone else and had no experience in teaching others.

It's a shame he was a teacher before he transmigrated; now that he's in the underworld, his professional ethics seem to be declining.

"No, no, my ambitions are completely ruined, this absolutely cannot happen..."

Thinking of this, Li Xuan remained calm and reassured himself.

In his mind, he should be a gentle, elegant, and understanding teacher.

The library has such a strong academic atmosphere; it's a great place to study.

Therefore, Li Xuan also believes that he is no longer the war demon of Ashikawa, but a senior learner and a potential teacher. He should be more patient and thoughtful with Komachi, who has asked him for help.

Teaching must be done with love.

We must learn to be considerate of students.

We need to be understanding.

There must be love...

However, as Li Xuan pondered the principles advocated by these teacher psychology principles, he took a few steps and saw, across a bookshelf in the library, the Undying Dragon in sportswear tutoring a boy with thick eyebrows; further away, Mad Dog Majima and Dojima no Ryu were reading a book with a little girl with a single ponytail...

The puzzle that could still be found by the window on Saturday has been solved...

Chapter 113 The Library's Tutor

This sacred place has been defiled, as if a group of demons were witnessing something here in the church!

Li Xuan was speechless, looking at this group of gangsters.

The group of people in front of me are all at the level of team leader or above, and are well-known yakuza in Japan. I don't know what evil wind blew them here today.

But it's clear they're teaching children, which is like a group of five-star, highest-danger prisoners in Florence, USA, doing charity work at an orphanage—it's utterly unbelievable and unheard of.

Indeed, this place is close to Qiancang Street. Li Xuan often studies here while working, which is why he chose this place as the destination for the study session.

"What's gotten into these guys today? What are they doing here?"

Li Xuan stood by the bookshelf, his mind filled with unease.

As a result, during the process of eavesdropping on the teachings of the immortal dragon, he realized that the chubby little boy with thick lips was the neighbor's child, who had been asked by the child's mother to tutor the child's homework.

Thinking back, when he was studying at teachers' college, he had never done any internships or heard anyone give a lecture.

Although Li Xuan also felt that the guidance from the Undying Dragons wasn't very valuable, they were all retired yakuza bosses, and their seasoned leadership skills, having once dominated their respective areas, were undeniable. Their backgrounds were similar to his, and being native Japanese, they should understand better than him how Japanese tutors operate. After realizing his own significant problems while tutoring Komachi, Li Xuan patiently hid to the side and observed how they taught the child.

【The Undying Dragon】holding a math textbook, he habitually looked up at people with an expression that hardly resembled that of someone teaching elementary school math; it was more like he was meeting a new underling.

“Learning mathematics well is a very important subject.”

The immortal dragon was telling the child beside him about the wonders of mathematics.

It turned out to be the case.

Upon hearing this, Li Xuan realized that the immortal dragon was not to be underestimated.

By explaining the necessity of learning from the very beginning, students must understand for themselves why they are learning, which can immediately motivate them.

"Kid, listen to me. If you're in the underworld and you can't do math, you're not even qualified to carry someone's shoes."

The Undying Dragon spoke with a ferocious expression.

"A loan shark needs to understand debt collection methods, discounting methods, and interest rate calculation methods. If you miscalculate the interest, you'll have to make up for any missed amounts yourself. Also, when acquiring land, you need to understand how to calculate land area and approximate building area. Don't expect to always have someone who can measure with you; if you overcalculate by even one square meter, you'll lose your shirt. And even in a fight, you need to be able to do math: how many people are on our side, how many are on their side, what's the relative strength of both sides when a fight breaks out... Now you understand, right? Mathematics is a crucial skill in every industry." The Undying Dragon explained with a somber expression that even in the underworld, education matters.

I always felt that these cases were all based on personal experience.

But is this really suitable for use as a teaching case?

Li Xuan peered through the gap in the bookshelf and was already speechless, stunned by Long Lei's words.

Strangely, the neighbor's child acted as if nothing had happened, nodding and saying, "I understand, Uncle Long."

The Undying Dragon said, "Alright, let's begin the lesson. What don't you understand?"

The child opened his textbook and said, "During class, I didn't understand addition, or anything about carrying over. I didn't understand at all."

The immortal dragon remained silent for a moment, then used a piece of paper to demonstrate and gave an example.

"It's like your class suddenly has to merge with the class next door. How many students are in your class and how many students are in the class next door?"

“There are 35 people in my class, and 36 people in the neighboring C class.”

"...The concept is very simple. Imagine that your two classes have conspired to merge. Your class has 35 students, and the neighboring class has 36. So, the total number of students in both classes seems quite large, right? But in the world of mathematics, it's about choosing a leader from ten people. So, with more students, your class originally had 35 students and only three leaders. But after the neighboring class joins, a new round of power struggles begins."

"The five unaffiliated students in your class and the six students from the next class were all fiercely competitive, so they arranged a brawl behind the school to form new groups of ten. You ended up at the back, and the weakest guy was your deskmate, so you didn't include him in your group. Therefore, of the six leaders from the two classes, you're now the new leader, and the rest are still there—the remainder. There's nothing we can do; the school only allows ten people per group..."

The immortal dragon revealed a strange expression of lust for power and told a vivid story about the right to survival.

The neighbor's child's expression seemed to indicate that he not only understood the meaning of mathematics, but also the cruel nature of society.

Li Xuan closed the books on the bookshelf, feeling that he could no longer watch the Undying Dragon's lectures.

He had heard that the Undying Dragon came from an extreme family, and that this learning method might be related to his upbringing.

However, Dojima no Ryu and Mad Dog Majima were both from commoner backgrounds and were people who actually attended public schools in Japan.

In fact, Li Xuan was starting to doubt these guys, but since he had nothing better to do, he couldn't say their teaching was completely useless. Even counterexamples are valuable experiences, and Li Xuan needed to learn from them. Soon, he abandoned the Undying Dragon and went to the teaching site of Kiryu Kazuma and Majima Goro to observe their teaching methods.
