Tanjiro's anger was at its peak, especially with the story's background setting, which directly exposed his scars. His family was killed by Muzan Kibutsuji, and his sister was turned into a demon.
He had found a master who helped stabilize his sister's condition, at least temporarily preventing her from eating people. But now, someone was actually trying to attack students in school?
Although he didn't fully understand the plot or the setting, the system clearly told him that the things these people did were the same as what Muzan Kibutsuji did to turn his sister into a demon, and even more cruel.
Tanjiro's determination made the team leader, who was holding a large shield, look at him closely: "Boy, you're in good shape, but remember, when facing firearms, your anger is worthless. Adjust your mood and stay behind me!"
"Yes!"
Unlike ordinary operators, Tanjiro's equipment included an assault rifle and a pistol, and his special skill was to use a katana to charge and attack. It was hard for Tanjiro to imagine that this was actually a game, especially with the realistic texture of the guns, the feeling of killing people, and the attitude of the NPCs around him. It felt like another world, yet he could still sense his body's state in the real world.
His body clearly told him that this was a game, not reality, and even death was not real death, but just a return to the mission's starting point.
However, Tanjiro did experience the power of modern special operations. The water breathing technique he had learned was useless except for improving his physique and making him draw his sword and shoot faster in sudden encounters.
Did he want to go up and fight with the his sword? The sniper on the opposite side could shoot him, and his body might still move, but his head would be gone. Hide behind the wall and attack? The heavy machine gun on the opposite side would fire, and grenades and RPGs were free.
The leader of the Rainbow team also woke Tanjiro up with some key advice.
"Remember, as long as it is a carbon-based organism, it has its limits. High temperatures can kill it. If it can't be killed, it means the temperature is not high enough."
"What do you mean there are organisms that aren't afraid of poison? How is that possible? Come on! If one day you really encounter an organism that can be resurrected, bring me some samples."
"What if you encounter a vampire? Hang it on the street lamp. If it's afraid of the sun, use this sunlight simulator. It simulates sunlight 100%, but it can cause some skin damage."
In the Rainbow Squad, Tanjiro's thoughts gradually changed. In a week, he successfully reached the Trial Mountain, wrapped in countless wisteria flowers.
Now Tanjiro had successfully cleared the entire Rainbow Six game and obtained the weapons and equipment bound to the operators. Unfortunately, he felt too stupid, not having learned the various knowledge taught by the experts, and only knew some basic combat.
However...
Before the assessment, Tanjiro carefully observed the people around him. There were all kinds of individuals around him, including golden-haired people who looked scared, indifferent-looking girls, and those who appeared very scared but gritted their teeth for their beliefs.
"The demon... is extremely evil..."
In seven days, Tanjiro understood a crucial truth: the blade has its limits, and only sufficient firepower and advanced technology are key to subduing the demons.
He remembered the doctor's words clearly: "I don't know where you read the comics or games, but I tell you clearly that if your bladd can hurt the demons in your story, then this will definitely work."
The 12.7mm caliber heavy machine gun weighs 26 kilograms. The doctor showed Tanjiro the power of this weapon. A large animal could be directly cut open with one shot, and a human-shaped target could be directly broken with one shot.
It is difficult for a demon to penetrate a two-centimeter thick steel plate, 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 demon 'conceived' in Tanjiro's mind. The heavy machine gun was just to explain the concept to Tanjiro, so that he could understand how horrifying modern weapons are.
At the same time, he also asked someone to test it, and he opened fire with all his strength.
Seven steps away, the gun was fast. Within seven steps, the gun was fast and accurate.
It was not until he understood all the guns and grenades in actual combat that he was more certain that firearms were the technology to kill demons.
Tanjiro began the trial. The breathing method and swordsmanship he learned were not in vain. Through continuous fighting, Tanjiro gradually understood a truth.
The sword is a weapon for killing, and sword skills are the technology to kill demons. No matter how gorgeous the language is, this is always the fact. And the gun is also a weapon for killing, and gun fighting skills are the technology to kill people.
He replaced the sword with a pistol and a submachine gun of equal weight. To better use the water breathing method, he kept fighting in the game. In every anti-terrorism operation, he rushed to the front to combine the breathing method and gun skills, and finally completed a fusion of both.
Walking into the forest, Tanjiro changed his weapons and equipment after seeing that there was no one around.
He wore a tactical eyepiece on his head, which could detect all creatures within the field of vision.
He had three grenades, three magazines of bullets, a Magnum tied to his waist, and a Negev light machine gun on his back, equipped with high-explosive rounds. According to the doctor, if a creature is hit by a high-explosive round, it will not survive.
He also brought a knife, but kept it in the system space.
Additionally, he had a flashlight that could emit simulated sunlight, and the battery used inside was made with the special technology of the Rainbow Team. The Rainbow Team equips outstanding operators with exclusive equipment, which can only be used by individuals. If damaged, they can be reported to the logistics department for replacement, but the technology must not be leaked to the outside.
Tanjiro also remembered this, so when he equipped these items, he was particularly alert to his surroundings. Once everything was ready, he began his exploration.
The screams in the forest came one after another. Although the demons here were all weak, some of them died at the speed of light due to nervousness or fear, so Tanjiro didn't have time to rescue them.
"Wait a minute, I'm ready."
Equipped with a full set of gear, Tanjiro began to search the forest methodically. After a few steps, he didn't see any small demons, but he did see a big demon with hands all over its body catching people to eat.
"Stop!"
Tanjiro's sudden voice stopped the hand demon, and when it turned to look in Tanjiro's direction, a bright smile appeared on its face.
It saw a fox mask hanging on Tanjiro's head.
Only those who caught it would wear a fox mask. It was excited, but before it could speak, Tanjiro took out a heavy machine gun and placed it on the ground.
"Is there anyone behind you?"
The boy who had escaped the disaster shook his head hurriedly, and Tanjiro nodded and comforted him: "Cover your ears, the sound may be a little loud."
Ratatatatat!
The sound of gunfire echoed through the hilltop covered with wisteria flowers. This hand demon became the first demon to experience the technology of the 21st-century Rainbow Six world.
