I'm just an internet cafe owner

Liu Yuan sighed and patted Takashima Yuna on the shoulder: "Familiarize yourself with the menu and keep an eye on Tanjiro's internet activity. If you need anything, come find me in the lounge later."

"Ok."

Kisara curiously leaned closer and asked, "Hey? Is there anything fun to do?"

"Of course, there are. Yo-yos, real-life versions, you've seen them, right?"

"hiss!"

At that moment, Kisara suddenly had a bad feeling. Before she could run away, a rope was put around her neck.

"Insubordination? Then I'll show you what it means to have an inviolable boss's integrity."

"Huh? Boss, you still have some integrity."

“My lovely Miss Geng, I’ve made my decision. Today, it’s either you or me who lives.”

"Wait! So I'm going to die anyway?"

You guessed right, but there's no prize.

Kisara struggled, but her struggles were futile. Today was her first day speaking to the newcomers with great authority, and Kisara actually tried to undermine her? If she didn't show some authority, the branch would be in an uproar.

Amidst the whirring sounds of the break room, resembling a giant windmill, and Kisara's energetic pleas for mercy, a joyful day began.

Meanwhile, Tanjiro, having just started playing the game, finds himself in a strange place. He's in a building shrouded in yellow smoke, wearing a full-body hazmat suit, and standing before him is a man with a deep, resonant voice.

"Little ones! This gas attack requires your cooperation with the Rainbow Squad operators. Those who perform exceptionally well..."

Doraemon will be joining the Rainbow Team. Understand?

Tanjiro didn't understand what was going on, but instinctively answered "I understand" along with everyone else.

But soon, he received game data from the system. Tanjiro, a prospective operator for Rainbow Squad, codenamed Doraemon. Rainbow Squad came to the rescue after terrorists attacked the university with poison gas.

According to the information, this yellow gas can transform people into monsters who are afraid of sunlight and can only survive by relying on red blood cells. However, according to experiments conducted by the Rainbow Squad's doctors, if the toxin can be dispersed within twelve hours and all students are exposed to ultraviolet light for three hours, the virus can be destroyed.

The Rainbow Team's current mission is to destroy the poison gas bombs planted by terrorists within the school and eliminate all terrorists to prevent them from causing further damage.

Chapter 103 Tanjiro - Rainbow Six Version

Tanjiro's anger is now at its peak, especially given the backstory, which is practically reopening old wounds. His family was killed by Muzan Kibutsuji, and his sister was turned into a demon.

He also met his current master and, with his help, stabilized his sister's condition, at least temporarily stopping her from eating people.

But now, someone is actually trying to attack students who are in school?

Although he didn't understand the plot or the setting, the system clearly told him that the things these people used were the same as what Muzan Kibutsuji used to turn his sister into a demon, or even more cruel.

Tanjiro's imposing aura made the leader of the team, Big Shield, glance at him again: "Kid, not bad, but remember, your anger is worthless against firearms. Calm yourself down and come behind me!"

"Yes!"

Unlike regular operators, Tanjiro is equipped with an assault rifle and a pistol, and his special skill is to use a katana for a charging attack.

Tanjiro found it hard to believe that this was a game, especially the feel of the guns, the sensation of killing, and the attitudes of the NPCs around him. It could easily be mistaken for another world, yet he could also sense his physical condition in the real world.

His body clearly told him that this was a game, not the real world, and that even death was not death in the true sense, but simply returning to the starting point of the mission.

However, Tanjiro did indeed experience the power of modern special operations. The Water Breathing Technique he had learned was useless except for improving his physical strength or making it easier to draw his sword and fire his gun in sudden encounters.

Should you drive straight in and hack and slash? One shot from the enemy sniper and your body's still moving, your head's gone. Trying to ambush from behind a wall? The enemy's heavy machine guns are firing incessantly, grenades and RPGs are just like they're free.

Meanwhile, a single sentence from the leader of the Rainbow Team also enlightened Tanjiro.

"Remember, every carbon-based life form has its limits. Any carbon-based life form can be killed by high temperatures. If it can't be killed, it means the temperature isn't high enough?"

"What? You're saying there are creatures that aren't afraid of poison? How is that possible? Come on! If you ever encounter a creature that can resurrect, bring me some samples."

"What if you encounter a vampire? Hang yourself from a street lamp. Worried about sunlight? Here! This sunlight simulator is for you. It perfectly simulates sunlight, but it'll make you get a tan."

Within the Rainbow Team, Tanjiro's mindset gradually changed. Within a week, he successfully arrived at the Trial Mountain, which was enveloped by countless wisteria flowers.

Tanjiro has now successfully completed the entire Rainbow Six Siege and obtained the operator-bound weapons and equipment. Unfortunately, he feels he's too stupid; he hasn't learned the various skills taught by the experienced players and only knows some basic combat techniques.

but…

Before the test, Tanjiro carefully observed his surroundings. There were all sorts of people around him: a blond guy who looked scared, a girl who seemed indifferent, and someone who looked terrified but persevered for his beliefs.

"The ghost...is extremely wicked..."

In seven days, Tanjiro learned a lesson: swords have their limits, and only sufficient firepower and advanced technology are the keys to subduing demons.

He remembered the doctor's words clearly: "I don't know where you read the comics or played the game, but I'm telling you this very clearly: if your knife can hurt the ghost in your book, then this will definitely work."

The 12.7mm caliber heavy machine gun weighs 26 kilograms. The doctor demonstrated the power of this weapon to Tanjiro. A single shot can rip open a large gash in a large animal and shatter a humanoid target.

Even a two-centimeter-thick steel plate would be difficult for a ghost to penetrate, but a heavy machine gun can penetrate it directly.

According to the doctor's description, heavy firepower is not even needed to deal with the demons that Tanjiro imagined. The heavy machine gun was just to explain the concept to Tanjiro and let him understand how terrifying modern weapons are.

He also had someone test his skills, going all out. From seven paces away, the gun was fast. Within seven paces, the gun was both fast and accurate. After mastering all the firearms and grenades in actual combat, he became even more convinced that firearms were the key to killing ghosts.

Tanjiro began his trials. The breathing techniques and swordsmanship he learned were not in vain. Through constant battles, Tanjiro gradually came to understand a principle.

A sword is a weapon, and swordsmanship is the art of slaying demons; no matter how eloquently it is used to mask this fact, it remains true. A gun, too, is a weapon, and marksmanship is the art of killing.

He replaced his sword with a pistol and submachine gun of equal weight, and even practiced the Water Breathing technique extensively in the game to better utilize it.

During counter-terrorism operations, he was always at the forefront, combining breathing techniques with marksmanship, and eventually achieving a fusion of the two.

After entering the forest and finding no one around, Tanjiro changed into his weapons and equipment.

Wearing tactical goggles on their heads, they can detect all creatures within their field of vision.

He had three hand grenades strapped to his waist, three magazines of ammunition, and a Magnum pistol, and a Negev light machine gun on his back, equipped with high-explosive rounds. According to the doctor, any living being hit by a high-explosive round would not survive.

I also brought the knife, but I put it in the system space.

In addition, he carried a flashlight that emitted realistic sunlight, powered by a battery manufactured using Rainbow Squad's special technology. Rainbow Squad equips outstanding operators with exclusive gear, which is for personal use only. Damage can be reported to logistics for replacement, but the technology must never be leaked.

Tanjiro kept this in mind, so he was especially vigilant about his surroundings while equipping himself with these items, and only after everything was completed did he begin his exploration.

Screams echoed through the forest. Although the demons here were all incredibly weak, some were killed instantly due to tension or fear, leaving Tanjiro no time to come and save them.

"Wait a little longer, I'm ready."

Equipped with full gear, Tanjiro began a thorough search of the forest. However, after only a few steps, instead of seeing Ki, he spotted a giant demon covered in hands grabbing and eating people.

"stop!"

Tanjiro's sudden voice made the hand demon stop. When it turned to look in Tanjiro's direction, a bright smile appeared on his face. It saw that Tanjiro was wearing a fox mask on his head. Only the person who captured it would wear a fox mask. It was excited, but before it could speak, Tanjiro pulled out a heavy machine gun and placed it on the ground.

Is there anyone behind us?

The boy who had narrowly escaped death quickly shook his head, and Tanjiro nodded to comfort him, "Cover your ears, the sound might be a bit loud."

And so, the sound of gunfire rang out from the wisteria-covered hilltop. This one-handed ghost became the first ghost to experience the technology of the 21st-century Rainbow Six world.

Chapter 104 Within Seven Steps, the Gun Was Fast and Accurate

Water Breathing is the easiest breathing technique to learn among the five schools in the Demon Slayer world. At the same time, there are many other breathing techniques derived from this one, and the extent to which one can use them depends entirely on the user.

In the world of Rainbow Six, doctors and several people with a deep understanding of human anatomy have studied the secrets of Tanjiro's breathing technique. According to the doctors, this breathing technique can make all organs and cells in the body very active and generate energy for a certain period of time, and this energy can be released by the user.

As for the harm to the body? Almost none. Most cells in the human body are renewed every few months. Even if you use up all the energy in these cells, it will only shorten the time from several months to a few weeks, which has almost no impact on life.

However! The improvement in physical fitness brought about by the breathing method greatly intrigued the doctor, but he abandoned the research after conducting it.

In addition to this, there's Tanjiro's sense of smell, which is even more sensitive than a dog's nose, making the doctor very curious. However, by combining Tanjiro's sense of smell with breathing techniques and firearms, a very effective strategy has indeed been found for him: 'critical strikes' against vulnerable points.

His sense of smell allows him to detect the weaknesses of enemies, which is quite mysterious, but the doctor confirmed this after many tests. So in the game, the Rainbow Squad operators trained his talent like crazy.

While not exactly masterful, it can still pinpoint weaknesses on a battlefield filled with the smoke of gunpowder through its sense of smell.

The Hand Demon, the most powerful demon on the entire assessment mountain, possessed arms so tough that even swords and blades couldn't pierce them. However…

“I can smell it. You’ve eaten many people. You… are beyond saving. Here… this is your weakness! Rest in peace. I won’t inflict too much pain on you.”

Tanjiro didn't fire his gun first. Instead, he took out his sword and seemed ready to fight head-on. His other weapons, like the strange glasses he wore on his head and the fire poker on his back, didn't seem to pose any threat to the demon.

"Die!!"

At this moment, the Hand Demon recalled the past, when it had just been born and was captured by the masked man and brought to this sunless mountain forest. The surrounding wisteria flowers left it nowhere to escape, and it had to endure hunger every day, waiting for the few people who would participate in the trials each year.

Fortunately, it ate all the disciples of its mortal enemy, and today it will eat Tanjiro too.

"Hehe, that little girl I met before was one of them. She was clearly very weak, but just like you, she wanted to protect everyone. I tore her in two."

"And that masked guy, tsk tsk, his head's all shattered."

The cunning of the Hand Demon exceeded Tanjiro's expectations. In the past, he might have been enraged by this scene and even rushed at it. But the Saisai Sixth Squad had been through too much.

Saving students, rescuing slum dwellers, counter-terrorism inside skyscrapers, even defusing bombs and taking down people by plane—none of these tasks were easy. Sometimes the enemy would use allies or civilians as leverage.

At first, he was prone to impulsiveness, but under the guidance of the doctor, he gradually learned to calm down.

In that instant, he recalled his conversation with the doctor.

"Doctor, why did you join the fight?"

Why

"What? Because I want to protect the innocent. Psychologically speaking, I'm an altruist. According to you anime and game fans, I'm a saint, but not one with 'saintly syndrome.' Remember, mercy towards the perpetrator is persecution of the innocent. If you encounter an enemy one day, just kill them."

They know all too well about "homebody" doctors. Rainbow Six Siege has a Japanese operator who spends all his time hugging his drones and naming them "wives." He even did some research on the culture surrounding them, and finally decided on one thing: that guy is beyond saving and can just wait to die.

Now he must exorcise this hand demon!

He took a deep breath, and ripples like water appeared on his weapon. The Hand Demon sensed the change in Tanjiro's aura, and a bright smile appeared on its mouth, which was covered by its large hand.

"Just be angry! And let anger become my sustenance!"

Whether it was the last person it ate or the one before that, none of them were weaker than Tanjiro, yet they all became its food. It believed that Tanjiro would also become its food and become part of its strength.

"Water Breathing, Fifth Form..."

Tanjiro had already charged forward, thirty steps, twenty steps, ten steps.

The distance between the human and the demon was getting closer and closer. At such close range, the demon felt that it couldn't possibly miss its attack. But it didn't matter. It was very patient. Tanjiro's sword couldn't break through its defense. It would wait for Tanjiro's failed attack and moment of surprise before launching a sneak attack.

Nine steps! It saw Tanjiro raise his sword.

Eight steps! It saw Tanjiro sheathe his sword in a second.

Seven steps! Tanjiro took out the strange weapon from his back and aimed it at it.

"Sorry, times have changed!"
