In the anime, Ai Li's father really doesn't want to be a yellow-haired man

Jumping power: 20m

Running speed: 100m/8.9s (normal time)

What level of power is this?

Xiaosan uses a typical family car as an example. At 120 km/h, the impact force is estimated to be over 10 tons. Impact forces vary significantly depending on the car model, speed, and collision conditions. A car weighing 1.2 tons will generate a force equivalent to 10 tons; a car weighing 1.6 tons will generate a force equivalent to 13 tons. A fully loaded truck traveling at high speed can generate a force of several hundred tons.

"In short, it's not as powerful as a heavy truck. But in terms of defense, the impact of a heavy truck shouldn't be able to break the mask armor's defense... right?" Xiaosan was a little unsure.

2. Knight Mode: Increased speed, reaction time to 0.05s (normal), but reduced strength. Specializes in melee combat. Its kicks can atomically disintegrate and destroy enemies. Its defenses can withstand 50-caliber machine gun fire and withstand temperatures ranging from absolute zero to 5000°C. A drop from 500 meters will not harm the wearer.

It seems that being able to defend against a “500-meter fall” is a very strong defense, but is it actually the case?

But to know the force it generates when it hits the ground, you need to consider factors such as air resistance (although when falling from a high altitude, this factor becomes relatively small when it hits the ground), the speed at impact, the mass of the object it hits, and the duration of the impact.

However, Xiaosan, who was "doing two things at once", did not want to complicate the problem, so he omitted the air resistance, the hardness of the ground, and the shape of the object, and only used simple physical formulas to calculate the speed when hitting the ground.

$v^2 = 2gh$

h=500 meters

$v^2 = 2 × 9.8 × 500$

$v^2 = 9800$

v ≈ 99

Kabuto in his Knight Form weighs 95 kg. The mass of an object does not change its speed or acceleration during free fall, but it does affect the force of impact when Kabuto hits the ground.

Next we can use the momentum theorem.

$F = frac{Delta p}{Delta t}$

Since the velocity changes from $v$ to 0, $Delta v = v - 0 = v$.

The previously calculated velocity $v approx 99$ m/s gives: $Delta p = m times v = 95 kg times 99 m/s = 9405 kg·m/s}$

To complete this calculation, you always need a reasonable estimate of the time of impact. This value is difficult to determine precisely...it depends on many factors, such as the hardness of the ground, the flexibility of the body, and the posture at the time of impact.

It was still in motion, so Takashi San couldn't concentrate. He just made a rough estimate, assuming that the impact time was between 0.1 and 0.2 seconds, and ignored other factors.

Use these two time values to perform calculations:

$F_{text{max}} = frac{9405 text{ kg·m/s}}{0.1 text{ s}} = 94050 text{ N}$

$F_{text{min}} = frac{9405 text{ kg·m/s}}{0.2 text{ s}} = 47025 text{ N}$

Maximum impact force $F_{text{max}}$ converted to tons: $frac{94050 text{ N}}{10000 text{ N/t}} = 9.405 text{ t}$

Minimum impact force $F_{text{min}}$ converted to tons: $frac{47025 text{ N}}{10000 text{ N/t}} = 4.7025 text{ t}$

Therefore, a 95kg Kabuto falling from 500 meters would generate a force between 4.7 and 9.4 tons. From this perspective, the Kabuto's defenses aren't that exaggerated... maybe a dump truck could actually penetrate its defenses?

Takashi San had also experienced a 100m/5.8s speed. It was fast, really fast... compared to an average human. A cheetah's top speed is 100m/3.4s.

The good news is that theoretically Kabuto can run at a speed of 60 kilometers per hour, which is faster than the cars on the street; the bad news is that it looks very uncool to run like this; the good news is that when he runs during the time-up period, others cannot see him; the bad news is that running for a long time like this is very tiring and consumes a lot of energy (especially after being drained by Altria).

The last time Takashi San fought a monster, he first transformed into Kabuto, used "Clock up" to enter the time-up state, then rode a small electric scooter to the scene, and then canceled the time-up and transformation... The reason for not driving is that the roads in the three central districts of Tokyo are also very congested at night. The surrounding time is relatively stopped, and vehicles cannot pass at all. Moreover, Kabuto is too big to squeeze into the driver's seat of a car, and the horns on his head can break the roof of the car.

These are all very real questions. Can you imagine Kabuto, after entering a "time-stopped environment," pretentiously finding a small electric scooter (Jackie Chan: Borrow it, I'll return it to you next time) and slowly rushing to the scene of the incident? Fortunately, no one saw it; to others, it was a fleeting moment. (Simplicity is the truth.jpg)

Besides these, Xiao San is also concerned about...

"Are there no other weapons?"

He remembered that knights all had all sorts of gadgets. Even the poorest knights had a motorcycle, right? Otherwise, what kind of knight would they be?

This situation is equivalent to: buying a car, but it is a bare car, or the lowest-equipped one, without any supporting equipment.

Kabuto is like that...

Just the Kabuto Insect Meter and the Knight's Belt, nothing else.

At this moment, the system's emotionless mechanical voice sounded, "The host has equipment requirements, and the exclusive item copy is open."

Immediately, the following interface flashed on the retina:

Kabuto Exclusive Item Dungeon 1: Demon Slayer, Dungeon Rewards: Perfect Insect Meter, TheBee Insect Meter, Drake Insect Meter, Sasword Insect Meter, ZECT Cone Drill...

Kabuto Exclusive Item Dungeon 2: Slash the Red Eyes. Dungeon Rewards: Insect Transcendence Instrument, Kabuto Kunai Gun, Kabuto Awl, Kabuto Extender, Faiz Belt...

Chapter 48:047 Want Haipa Kabuto: Sorry, Horikita Suzune, I have to continue bullying you

Takashi San carefully slipped out from under Altria and pulled the massive screwdriver out of the tight vise. Altria's face flushed with exhaustion, her breathing steady. Takashi San covered Altria with the blanket... and as he dressed, he planned what he would do next.

Whether it's "Demon Slayer" or "Akame ga Kill," the system prompts are "a safe world that can be completely controlled by the host's ability." This makes Xiao San feel... 'very suspicious.'

These names sound like they should be from a fighting anime, and they have all kinds of weird abilities.

(Demon Slayer: Kimetsu no Yaiba was serialized on February 2016, 2, after the death of Kozo's previous life. While Kill Akagi began serialization in 15, it has only had a few chapters, and the weekly manga it was published in is not subscribed to by Kozo.)

However, based on the differences in the details of the copies, Xiao San can make a guess...

Kozo remembers that the Insect Transcendence Instrument should be the item that can evolve Kabuto into his ultimate form. The latter (Aka-slashing) has a stronger reward, so it should also be more dangerous, right?

But now Takashi is faced with the problem that Kabuto's base form doesn't have the ability to travel through time and space, and his time-shifting only increases his speed relative to the surrounding speed. If he wants to return to Airi and the others, he can only try to obtain Kabuto's final form.

At night, the school gymnasium was deserted, with only a few street lamps emitting white light. Horikita Suzune stared at Horikita Manabu's back intently... His back was like an insurmountable wall, but it was also the goal she wanted to cross.

"I am no longer the loser that brother knew me as. I came here to catch up with you." Horikita Suzune's voice was particularly clear in the silent night.

"To catch up with me? You still don't know your shortcomings! Choosing this school is your failure." Horikita Manabu said calmly without turning his head, without any emotional fluctuation in his tone.

Horikita Suzune's momentum instantly weakened like a popped balloon. She bit her lip and said, "I'll catch up with Class A right away, so..." Her voice gradually faded as she went on.

"Impossible." Horikita Manabu interrupted her.

"I will definitely do it." Horikita Suzune whispered.

At that moment, time seemed to stop, and everything around them fell into an eerie silence. The resolute expression on Horikita Suzune's face, which had not yet faded, was frozen, and Horikita Manabu's movement, which was about to turn around, seemed to be frozen in time.

Kabuto stood beside them without warning, his red armor gleaming in the dim moonlight. He held Horikita Manabu's student ID card in his hand, his eyes fixed on the photo and information on it, comparing it to the man before him. "Judging from their conversation just now, this must be Suzune's brother." (Kabuto had already searched the entire school in his time-transformed state.)

"Although I feel very sorry for doing this to you, but..." Kabuto slowly reached out his hand, patted Horikita Manabu's shoulder, and said apologetically: "The situation is urgent, so I have to inconvenience you for now. I will make it up to you later."

Next, time resumed, but Kabuto had disappeared without a trace.

Horikita Manabu continued his actions, turned around suddenly, grabbed Horikita Suzune's wrist with lightning speed, lifted her wrist high, and pressed it hard against the wall.

Horikita Suzune's face instantly revealed an expression of pain, and her body trembled slightly.

"It's my sister who was assigned to Class D, and I'm the one who's embarrassed in the end. Leave the school immediately." Horikita Manabu said coldly with a frosty face, without a trace of warmth in his eyes.

Horikita Suzune closed her eyes, tears welling up in her eyes, "Brother, I..."

"You are not qualified to climb up." Horikita Manabu pointed his other hand at Suzune's abdomen, as if to hit her.

Horikita Manabu's palms were tensed, and he was about to deliver a ruthless blow to Horikita Suzune's abdomen. Horikita Suzune closed her eyes and prepared to be beaten.

At this critical moment, a voice suddenly rang out, "Grandma said..."

Horikita Suzune and Horikita Manabu both looked in the direction of the sound.

In the moonlight, the figure of a young man stood on the wall. "Grandma said there are two things men should not do: make girls cry and waste food."

Horikita Suzune tried hard to see the other person's handsome face, "Yukinoshita."

Horikita Manabu also saw the other person clearly. "That guy from Class D who always skips classes." (The student council president has access to all the student records in the school. There are only about 300 students in this school, so it's not difficult for the student council president to remember all of them.)

With a light leap, Takashi San landed beside Horikita Suzune. His movements were clean and smooth, without the slightest delay. He quickly extended one hand and precisely grasped Horikita Manabu's wrist, using just the right amount of force to stop Horikita Manabu's movements without injuring him.

As Kozo squeezed hard, Horikita Manabu's hand loosened involuntarily. Then he casually shook it off, and Horikita Manabu couldn't help but take two steps back.

"What a strong force!" Horikita Manabu was surprised.

"Yukinoshita, don't worry about this matter." Horikita Suzune said anxiously.

However, Kozo acted as if he hadn't heard Horikita Suzune's words. He slowly turned around, his movements possessing an innate grace and composure... At that moment, his gaze fixed squarely on Horikita Manabu. Their gazes met, and invisible sparks flew through the air.

A look of vigilance unconsciously emerged on Horikita Manabu's face, and there was a wavering in his originally calm eyes... He couldn't see through the other person, and he felt a sense of oppression from the other person that was far stronger than his own.

You know, in this school, as the president of the student union, he has always been a high-ranking figure. But now, for the first time, he has lost to another student in terms of momentum. This feeling is like a general who has always won and suddenly suffered a Waterloo. He is filled with resentment.

"Are you an elite?" Xiaosan asked sharply.

Just as Horikita Manabu was about to answer, Kouzo interrupted rudely, "I don't want Suzune to be with a leisho, so you'd better stay away from her."

In Horikita Suzune's eyes, he was like a knight protecting a princess, not allowing anything he considered bad to get close to him. But... that was her brother.

Horikita Manabu attacked instantly, his movements as sharp as the wind.

The moment the palm was about to touch Kozo's shoulder, Kozo reacted quickly, took a step forward, and his fist reached Horikita Manabu's abdomen like lightning.

Fifth degree in karate...

Aikido 4th Dan...

This is Horikita Manabu, the perfect brother in Horikita Suzune's eyes.

But compared to the numerical oddity of "Tendo Souji's physical fitness", it is ultimately not worth mentioning. Moreover, he is currently imitating a certain karate master who is unbeatable in Japan.

Horikita Manabu felt an unbearable pain in his abdomen. The powerful impact brought his attack to an abrupt halt. He bent down involuntarily, holding his abdomen tightly with both hands, and beads of sweat the size of beans kept rolling down his forehead.

Everything happened so fast that Horikita Suzune didn't even react. She just stood there in a daze, her eyes full of confusion.

Horikita Manabu endured the pain in his abdomen and raised his head. "Fighting is prohibited in school. Aren't you afraid that I will have you expelled from school?"

"I don't want to be in the same school with Le Se." Kouzo's expression was cold and his tone was full of disdain. His eyes only showed endless contempt for Horikita Manabu.

Xiaosan said to Lingyin expressionlessly, "Lingyin, don't stay with Lese, come with me." After that, he put his hands in his pockets and left, with a casual and unrestrained posture.

Horikita Manabu stared at Kozo's departing back, his eyes filled with anger, frustration... and even indescribable complex emotions. His fists were clenched tightly, his nails almost digging into his flesh.

This was the first time he had ever been so embarrassed in front of his sister...

This was the first time he was humiliated in front of his sister with such "lese"...

Horikita Suzune finally woke up from her dream and quickly stepped forward to support Horikita Manabu, asking with concern, "Brother, are you okay?"

At this moment, Xiao San's pace slowed down. "By the way," he said calmly without turning around. "I've recorded the entire situation. If Le Se doesn't mind being embarrassed, I can spread the video. By then, all the teachers and students in the school will know that you, the student council president, started the fight but couldn't beat him, and even tried to abuse your power for personal gain... Such a shameful thing. By then, my image as a perfect student council president will probably be shattered, right?"

The simplest and most direct way to inflict pain on someone is to...humiliate them face to face, then beat them up. Kouzo deeply disliked this harsh practice, but he simply couldn't bear to wait any longer. Desire begins with "acquisition" and "expectation." Having Kabuto, he wanted Hepa Kabuto. With the opportunity to return within reach, Kouzo's anticipation grew stronger.

"I'm sorry, Suzune's brother." Kouzo apologized in his heart while saying these cruel and humiliating words.

This kind of physical and mental humiliation made the usually arrogant Horikita Manabu furious. He showed no appreciation for his sister's support and rudely pushed Horikita Suzune away.

Horikita Suzune was caught off guard and stumbled back several steps. Her foot seemed to be tripped by something and she fell to the ground. "Hmm..."

The gentle and kind-hearted Kosan was filled with apologies towards the Horikita siblings, and kept feeling sorry in his heart (gentle and kind: I'm sorry, I shouldn't have hit you just now, I'm sorry, I love you, I'm sorry, sorry, sorry, sorry/confusion).

At the same time, he opened the system page:
