Hayate Sato is thin and weak. He is an orphan. Some people say that Hayate Sato's personality is too weird.

Although he has feelings such as joy, anger, sorrow, and pleasure, there is only a slight touch in his heart. His expression is always indifferent and there is no other change.

He is not very concerned about anything. But he is a man of action. Once he has determined something, even if it is full of dangers and difficulties, he will complete it.

Perhaps it is because he grew up in an orphanage that Hayate Sato lacks enthusiasm for many things. Now, the only thing that can excite him is blood. Whenever he sees a bloody and exciting scene, he will be excited.

This is also one of the reasons why Hayate Sato applied for a military academy. Another reason is that for any citizen of the empire, entering the military academy has all tuition fees waived, with food and accommodation provided, and there are also varying amounts of subsidies, although the subsidies are pitifully small.

To support himself, during the day, Hayate Sato attends classes at the military academy. At night, he goes to work part-time as an assistant to an anatomy doctor.

In fact, the anatomist himself rarely comes to work. Most of the time, it is Hayate Sato and these apprentices who complete the work for him.

They take out various organs of the corpse, weigh them, put them in fresh-keeping bags, and finally refrigerate them.

Nineteen-year-old Hayate Sato is now sitting in the classroom of the military academy, listening to the course taught by the combat instructor with twenty-nine other classmates.

The instructor is teaching them unarmed combat according to videos. Hayate Sato looks at the sky outside the window. White clouds are floating in the sky.

In his mind, he is thinking about going to watch the bloody and exciting "Death Mecha Fighting" competition with his classmates after school.

The death fighting competition is a real mecha fighting competition that has become popular in recent years.

Each contestant is either a mecha warrior from the enemy country, the Hundred Beasts Empire, or a death row inmate from the Tianlong Federation. In the battle, they will fight in real mechas.

The loser will be killed in the cockpit. Nineteen-year-old Hayate Sato, every time he sees the bloody battle scene in the arena through the protective screen, he feels his blood boiling. This kind of bloody scene makes him feel like a normal human being again. As a student majoring in mechas in a third-rate military academy of the empire, Hayate Sato will graduate from this run-down school in one year.

After graduation, he may join the army and become an ordinary mecha infantryman of the empire. Or he may take an anatomy qualification certificate exam and become a small citizen.

In short, everything is very plain for him now. A plain life and a plain life trajectory. However, what happens next changes Hayate Sato's life in the future. Hayate Sato vaguely saw a light white feather floating in from outside the window.

The feather slowly floated onto his hand and then disappeared in an instant. Just as Hayate Sato rubbed his eyes to make sure he wasn't seeing things, a voice sounded in his ear, "Host confirmation in progress. Initiating fusion."

Then Hayate Sato felt a sharp pain all over his body. Although it only lasted for a second, the pain that seemed to penetrate deep into his bones made Hayate Sato stand up suddenly and shout "Ah!" in the classroom. The classmates in the classroom all looked at him in surprise.

"Classmate? What are you doing? Sit down quickly!" The instructor said to Hayate Sato. Seeing that Hayate Sato didn't respond, the combat instructor came over, raised the teaching whip in his hand, and was about to whip Hayate Sato. Beating students is a very common thing in the third-rate militarized school where Hayate Sato studies. Hayate Sato, who was covered in cold sweat from the one-second pain just now, was about to sit down when he found that his body was out of his control.

He couldn't even lift his arms. His eyes, he couldn't even close his eyes. Hayate Sato could only stare wide-eyed at the teaching whip in the instructor's hand getting closer and closer to his head. "Spiritual power matches.

The god of war device initiates fusion. Activate the automatic scanning device. Before the fusion process, eliminate nearby dangerous creatures. Scan. The nearby danger level is 32, which is a primary danger.

Eliminate it." A cold electronic synthesized voice sounded in Hayate Sato's ear again. "What on earth is going on? Why am I having auditory hallucinations? Why can't my body move?" Hayate Sato thought like a bystander.

Next, Hayate Sato's body suddenly started to move, but it was not controlled by him. Hayate Sato dodged to the side and avoided the combat instructor's whip. With a speed that was hard to catch with the naked eye, he quickly extended his left hand and grabbed the opponent's throat with his five fingers.

Then with a "click", his five fingers closed. Before everyone could react, Hayate Sato broke the throat of the senior combat instructor who was teaching them in less than a second. The classmates around saw Hayate Sato's actions and became terrified.

They all looked at his actions in surprise. Hayate Sato wanted to explain, but found that his body was still out of his control. The instructor was actually killed by him. Hayate Sato, who had lost control of his body, was at a loss.

Of course, Hayate Sato's face was still as indifferent as usual. But seeing the fierce combat instructor who always beat students dead at his hands, with those big, bulging eyes staring, he felt a little excited. At this moment, the electronic synthesized voice sounded in Hayate Sato's ear again, "The attack has been eliminated. Activate the scanning device.

The nearby danger level is 14. Continue to clear." Then, Hayate Sato, who had lost control of his body, saw a scene he never wanted to see in his life. Hayate Sato, that is, his body, moved flexibly around the entire classroom and launched an attack on the classmates around. At this time, he was like the god of death.

Every attack was a one-hit kill. In less than a minute, he actually killed the twenty-nine classmates in this classroom. "Activate the scanning device. The nearby danger level is zero. Deep fusion can be performed." The electronic synthesized voice sounded again. "No!!!" Hayate Sato wanted to shout, but he still couldn't make a sound.

When this synthesized voice sounded in his ear, he found that he was sitting back in his original seat motionless. "Spiritual fusion successful." About twenty minutes later, when this cold electronic synthesized voice sounded, he regained control of his body again.

Looking at the thirty corpses in the classroom, including the instructor, and the blood all over the ground. The classroom that was still full of students a few minutes ago is now like a morgue.

Although Hayate Sato usually likes this kind of bloody scene, he still hopes this is a dream. Hayate Sato pinched his arm hard.

The pain made him know that this was not a dream. "Ding ding ding." The bell for the end of class rang. He knew that it was impossible to walk out of the classroom as usual.

The plain life had become a bubble. What should he do? Tell others that he was possessed by an alien and then killed all the classmates and the teacher within a minute? Even if he said it, no one would believe it.

Hayate Sato sat on his seat. His expression returned to indifference again. His eyes looked out of the window. The blue sky and white clouds were moving slowly. His eyes were empty.
