"In the vast Amazon plains, there lives a species of eagle called the Eagle Eagle, who has the title of King of Flight. Its flight time is long, its speed is so fast, and its movements are so agile that it can be called the most among eagles, and it is generally difficult for the small animals it finds to escape his capture. But who would have thought that behind that magnificent flight there was a tragedy of dripping blood.

"When a young eagle is born, it has to be trained by its mother for a few days without enjoying a few comfortable days. With the help of the mother eagle, it doesn't take long for the young eagle to be able to fly on its own, but this is only the first step, as this kind of flight is only a little better than crawling. Young eagles need to be trained hundreds or thousands of times, otherwise, they will not be able to get food from their mother's mouth. In the second step, the mother eagle takes the young eagles to a high place, or to the edge of a tree or a cliff, and then throws them down, and some of the young eagles are killed by their mothers because of their cowardice. But the mother eagle will not stop training them, and the mother eagle knows that without such training, the children will not be able to fly high in the blue sky. The third step is full of cruelty and horror. Because most of their bone marrow will be broken off from their wings, and then piled down from the heights, many young eagles will become sacrifices for flying and heroic. But the mother eagle will not stop this bloody training, because although there are painful tears in its eyes, it is also building the blue sky of children's lives.

"It turns out that the mother eagle cruelly broke most of the bones in the wings of the young eagles, because the eagle eagle wing bones have strong regenerative power, as long as they can endure severe pain and keep flapping their wings and fly after being broken, they will be healed soon after, and they can grow stronger and stronger. If not, the eagle will lose this only opportunity, and it will never have a chance with the blue sky. No one can help the eagle fly, except himself. ”

Kiri Kanharutani said calmly and gently, "Guataro, I have always treated you as my child...... I'm telling you all about this, I'm sure you probably know all about it, right? ”

Guataro's eyes were filled with tears behind his black-framed glasses, and his silver hair was tossed by the wind from the edge of the helicopter that opened the door on one side—just as he was feeling at the moment.

"Section Chief... That one... You're not trying to push me down, are you? ”

"How could I do such a cruel thing? What a silly boy. ”

Jin Chungu Tong pushed down his glasses with a straight face, "Of course you want to jump off by yourself." ”

"Whew—scared the hell out of me...... Not really!! Why should I jump myself!! ”

The height of the Twin Towers in Kyoto is about 400 meters, and the height of the fourth section of special warfare is about 500 meters, which is exactly 100 meters above the roof of one side.

If you fall from such a height, it will definitely become a mosaic!

"Guataro, there are a lot of techniques I'm good at. Among them, there are some divination techniques that are on the verge of being lost, and they can deduce things like a person's 'fortune' and 'fortune' in a small and small way. Don't worry, Guataro, you're not the man who will die here......"

"No, no, no, that has nothing to do with the current situation! And as long as you jump, you're sure to die!! ”

Guataro, who was already frightened, retorted nervously.

"In addition, your fortune today is 'good luck', even if you jump directly and land with your head, the survival rate is definitely above 80%. How's that, Guataro are you high and unhappy? ”

"It's not something to be happy about?!!

"I really can't help you, so take this......

With a doting smile like a fool's parent, Kaneharu took out a spear-like exorcism weapon engraved with dazzling golden runes and a sci-fi aura from the weapon box under his seat and handed it to Guataro.

The golden rune was a bit like the word 'Alien-Hunter' in round English, coherent and fluent, but imposing.

"The retractable E-hunter spear can reach a length of 13 meters when fully unfolded, and there are a total of five variations, and the cost of materials to build it alone is more than 100 million yen. Right now...... It's already yours, use it well, Guataro. ”

Guataro Kamijo hesitantly took the somewhat heavy weapon: "Thanks... Section Leader... However, I always feel like I've seen this weapon somewhere......"

"It's definitely not the Predator Spear from 'Alien vs. Predator'! Although it looks the same, this appearance is a complete coincidence! And where would there be a stupid person who sold his villa in Hawaii because he thought the iron-blooded spear was handsome after watching the movie, and then spent more than three years traveling all over the world and constantly searching for information to design and build such a toy?!! ”

Jin Chun Gu Tong's face suddenly stiffened, and he quickly argued.

“……”

Guataro and the other members of the Fourth Special Operations Division in the helicopter looked at the section chief with an extremely unnatural expression, and they all sweated together.

- There is only one such stupid person here!!

"Ahem... Guataro... Since I have given you such a precious exorcism weapon, you should also know the hope I have given you. How could I possibly allow my most promising future exorcist to face real danger before he could reach full wings...... Take this. ”

Guataro held the heavy exorcism version of the 'Iron-Blooded Spear' in his left hand, and hurriedly used his free right hand to catch the crystal hexahedron, which looked extraordinary.

About the size of a dice, there was a green rune quietly suspended in the crystal body, which looked very mysterious and obscure in the night, and it was a valuable treasure at first glance.

Not only is he a scholar in the usual sense, but Guataro, who also has some research on language and writing, and is barely erudite, has a great deal of confidence that this is a type of writing that he has never seen before. Most likely, it is also a script outside of the existing civilization system on Earth.

So, in every sense of the word, it's definitely not an ordinary thing.

“… Section Leader... What is it? ”

Although he didn't know how valuable this was, seeing the reluctant look of the section leader who didn't show any expression when he gave away the exorcism weapon worth more than 100 million, Guataro knew that this treasure in his hand could definitely be called a priceless treasure.

"At the top of Querigua is a Mayan stele with hieroglyphs, which archaeologists have accidentally deciphered from recognized Mayan scripts that it is a chronicle of the Maya people that chronicles events between 400 million and 90 million BC. But ......"

Jin Chungu Tong lowered his glasses and said lightly as if immersed in memories, "Everyone knows that the ancient apes on the earth appeared 1 million years ago, and the human civilization was only 5,000 years old, 400 million years ago, what kind of existence did the earth that was still in the Mesozoic Era leave such magical words, creations and miracles?" We don't know yet. But it was only the miraculous creations of the ones they left behind...... Already the greatest miracle of our time. ”

"Do you mean...... Is this the treasure of a prehistoric civilization that allows me to ignore the impact of the fall? ”

"Far more than that, the possibilities contained in this 'Crystal Rubik's Cube' are close to infinite."

Kinharu Tani Kiri, as if severing nostalgia, decisively took his gaze away from the crystal cube, and looked at Guataro Uejo with a wistful smile, and his eyes were full of hope in the depths of his eyes.

Guataro, who received such valuable gifts one after another, trembled slightly with excitement: "Class, section leader, this ...... It's so valuable. ”

"These things can only be worth and meaningful if you grow up enough to protect humanity from the monsters below. Don't let me down, Guataro. ”

“…… Don't worry, section manager. ”

Guataro took a deep breath, closed his eyes and tightly grasped the priceless crystal cube and the 'Exorcism Iron Blood Spear' in his hand, and suddenly calmed down, revealing an extremely confident smile.

Standing straight like a javelin by the side door of the helicopter, Guataro's silver hair danced like silver flames in the wind, and there was no trace of confusion in his voice, "-Who do you think I am?" ”

"I'm here! The ...... of the fourth lesson of special warfare"

Jumping suddenly, Kamijo Guataro fell into the air without fear, "Kamijo Guataro ahh

The passionate and heroic voice of the young man with the Doppler effect faded away.

"Well, it's time for us to go."

Slamming the side door of the helicopter shut, Jin Chun Gu Tong sat down, the expression full of complicated emotions on his face suddenly regained his calm, and turned his head to look at his old subordinates, "...... What's the matter, you all have such strange eyes in your eyes. ”

"No, no, no...... Although I knew that the section chief was proficient in almost all the spells that survived before, I didn't expect that you still have the treasures of prehistoric civilization...... He didn't even tell us. But yes, such treasures are too valuable to be measured in money......

Lesson 4 First Combat Effectiveness Guan Shiche involuntarily sighed.

"It is precisely this that shows how much the section chief values Guataro! That kid is really lucky......"

Spring Natsuki also stroked his long black hair that had slipped, and nodded while holding his jaw as white as jade.

"What are you talking about? How could that kind of thing be? ”

Jin Chuntani Tong had a dead face as a matter of course, "I lied to Guataro." ”

“…… Eh, eh? ”

The members of the fourth lesson blew up their nests, and one by one they watched with wide eyes as Jin Chun Gu Tong took out a bunch of crystal cubes embedded with characters of different colors and shapes from his pocket.

"This was originally a small gift I gave to Yu Fang's daughter Realm, and the glow in it is all worthless things such as energy storage phosphors, and most of the characters are my self-created exorcism runes, and the cost is about 500 yen each, if you want, you can also take a few of them as trinkets or something."

Jin Chun Gu Tong said indifferently holding a bunch of colorful crystal cubes on his right.

- Devil! There's a demon here!!

All the members of the fourth lesson remembered with great sympathy that Guataro was deceived by this demon and jumped from a height of 500 meters.

"There's one thing I didn't lie to him, though. Even if Guataro falls and faces a 'witch' directly, he has at least an 80% chance of survival. And if you count the fall alone, the chance of survival is more than 99%. ”

Jin Chun Gu Tong lowered his head slightly, and could only see the miserable white cold light reflected on the lens, "And we, about 75%. The highlight of this time is not just the two A+ level 'witches'. ”

Almost at the moment when these words fell, a shock wave like a nuclear explosion swept through the entire helicopter, and the fuselage quickly decayed and weathered as if it was speeding forward in the infinite time, becoming dilapidated, and the flames that rolled like a hurricane engulfed everything around it.

The world seems to have turned into an apocalyptic hell, with towers in ruins, the earth has dried up and cracked, lava has run rampant, and trees have been carbonized and lodging in endless scorching storms......

"Don't panic, it's just that the 'concept' in the A-class enchantment launched by the new exorcist in the strategy room is eroding the real world. These 'flames' and 'destruction' are not directed against us, otherwise we would have fallen long ago. Continue to fly towards point B, since the countermeasure room has shown its top combat power, then we can't lag behind in the fourth special warfare class. ”

Seeing the fighting spirit of not admitting defeat in the eyes of his old subordinates, Jin Chun Gu Tong also showed a confident smile.

- These guys, even if they know that they can't be defeated, will never give in and admit defeat.

This is the most valuable trait of exorcists who awaken their spiritual power on their own.

Unlike those exorcist families who are born with extraordinary spiritual powers, but are inferior to each other, only those who burst out with true power in the face of invincible horrors will awaken their spiritual powers and survive supernatural disasters.

It doesn't rely on innate spiritual power, it doesn't rely on inherited spells. These exorcists, who will never go extinct as long as there is a source of supernatural disasters, represent the infinite possibilities of humanity in the face of danger and despair.

This is also the reason why Jin Chungu Tong is always full of confidence in his subordinates-

The only way to defeat them is to kill them completely.

☆

At the same time—

"Ahh......h NOOOOOO！！！ ”

Guataro Uejo screamed in disbelief as he passed the side of the tall building and the roof that seemed to have fallen apart, and continued to fall rapidly.

“…… Chill off, calm down. ”

Guataro lifted his glasses and forced himself to calm down and analyze.

- When an object does not exceed 2.5 times the speed of sound, the air resistance is proportional to the square of the velocity. This positive proportional factor is about 1.5.

His weight is 60 kilograms, and the height of his fall is 500 meters.

Then, when the resistance is equal to its own gravity, it will reach its maximum speed and land at a constant speed until it hits the ground.

Suppose the maximum speed is V.

That's 60x10=1.5xV^2

V=20m/s=20x3.6km/s=72km/s can be obtained

In other words, this speed is nowhere near the rumored 300km/h. To reach this speed, it is only necessary to fall down to a height of about 50 meters.

- Well, it looks like there's no need to worry about next week's physics exam.

Guataro lifted his glasses and looked at the ground that was getting closer and closer, thinking with relief.
