"Before distinguishing between a half-demon and a real demon, I have to tell you what a half-demon is and how it came about. ”

Teacher Song said unhurriedly.

"Let's talk about the source first, there are two main sources of half-demons. ”

"One is demonic energy, and if you are infected by demonic energy, you will become a half-demon. This world is actually full of demonic energy, but ordinary people's eyes can't see these demonic energy. And it's different from hydrogen and carbon dioxide, which make up the atmosphere, to be precise, it's actually more like a ...... A virus. ”

"Virus ???" Mu Yun was confused when he heard it, and he found that the way Teacher Song was speaking at the moment had become a posture of a teacher teaching and solving doubts for students.

"That's right, demonic energy can infect other things like a virus. Once infected by the demon qi, after certain conditions, it will become a half-demon.

"And what's even more powerful than the virus is that demonic energy can also have an effect on inanimate items.

"For example, do you know the 'Fu Fu God' of the island country? In the folklore of the island country, old utensils are left unattended for 100 years, and then they absorb the essence of heaven and earth, accumulate resentment, or feel Buddha nature and spiritual power to obtain a soul, and then turn into a kind of monster called 'Fu Fu God'.

"These artifacts are actually demons that have been affected by demonic energy. ”

"Wait, according to what you say...... Mu Yun's hands trembled, gently rubbing the dashboard of the Toyota Crown, "This Toyota car is infected with demonic energy......, and it is possible to become a demon? Wouldn't you be a Transformer?!"

"Uh......" Teacher Song was caught off guard, and didn't know how to answer Mu Yun's brain-opening question for a while, so he simply chose to ignore it and continued: "Theoretically, flowers, birds, insects, fish, wood, stones, mountains and rivers, everything in the world can become demons. It's just that relatively speaking, living creatures are more susceptible to the influence of demonic energy, and the more advanced the creature, the more susceptible it is to demonize by demonic energy. ”

"Human beings, as the higher animals on the earth, bear the brunt. Especially in infancy, small children are not only particularly prone to illness, but also the most susceptible to the influence of demonic energy and become half-demons. ”

Teacher Song continued, "So, the half-demons we define are those things that exist in this world and are not originally demons but later became demons. Then there are the descendants of the half-demon.,Generally, the children born of the half-demon will also inherit the demon blood of one of the parents and become a half-demon.。 ”

"Wait, according to the definition you said, flower demons, cat demons, dog demons, and human ...... cough, if the demons that these animals and plants have become are all half-demons, aren't all the demons in the world half-demons, how can there be any pure demons?" Mu Yun asked.

"Pure Demon ......" Teacher Song frowned, feeling that the word sounded a little weird, but he couldn't tell what was wrong for a while, "The real 'demons' we are talking about are actually a group of ...... Freeloader. ”

"Uninvited guests?"

"Unlike half-demons, no one knows where the demons came from or where they came from. They always appear suddenly, and sometimes disappear suddenly. Some say they're extraterrestrial visitors, others say they're lurking in the center of the earth, and some say they don't belong to this world at all, but come from another dimension, from another parallel universe......"

"And then, what does they have to do with us?" Mu Yun asked again, "Everyone has the word 'demon', so it doesn't have anything to do with it, right?"

"Of course, it has to do with it, when the Europeans landed on the American continent during the Age of Discovery, they also brought epidemic viruses with them, which brought extinction to the Indians.

"—And the demonic energy of our world is likely to have been brought over by the demon clan during the invasion of the ancient period. In other words, the appearance of the half-demon, whether indirect or direct, is because of the demon clan in the final analysis. ”

Mu Yun listened quietly and swallowed his saliva.

"Besides, there is a hostile relationship between the half-demon and the demon clan. They are our enemies, our enemies forever. Teacher Song continued.

"Why?" asked Mu Yun.

At this time, the traffic finally re-flowed again, and the surrounding cars started slowly one after another.

"So, have you seen Pacific Rim, or Godzilla?"

Teacher Song said, "You can approximate the demon clan as the kind of big monster in the movie that comes from the universe or another dimension. ”

"They only bring destruction and destruction. During the flood period, there were still many demon clans, they roamed in all corners of the world, and they broke out countless wars with the people and half-demons at that time. ”

Teacher Song fiddled with the steering wheel and accelerated.

"Hou Yi shoots the golden crow, Susanoo kills Yagi, the battle of the Titans, and Ragnarok...... Many of these myths and legends have real prototypes, not all of them are groundless, these stories are actually projections of those dragons and tigers in ancient times. ”

"Now it seems that it was the humans and half-demons who won the final victory, after all, the demon clan is no longer rampant in this world. But our enemies have not disappeared completely, but still appear from time to time. Every time they appear, they still bring endless destruction, destruction, and chaos...... So to the world, they are nothing short of oosen, something abnormal. In the "Zuo Biography", it is said that 'when the sky is reversed, it is a disaster, and when the earth is reversed, it is a demon', and they are both 'disasters' and 'demons', so we also call them 'disaster demons' - this is the demon race, they are different from us, real 'demons'. ”

"I see, they are the enemies of the world. Mu Yun said.

"Yes, that's right. Teacher Song nodded.

"And then, the half-demon fights the demon clan, is responsible for protecting the peace of the world, and is the guardian of the world?"

"Guardian of the World...... This statement is too high-sounding. Teacher Song smiled, "Ability often means responsibility, and the half-demon enjoys great power, so it naturally shoulders the mission of suppressing the demon clan." Therefore, for thousands of years, every time the demon clan has recovered, the half-demon will go forward to fight against them, and have paid many sacrifices and costs for this.

"But in fact, risks often come with rewards, just like the story of Warrior Dragon Quest, the wealth and princesses that the dragon plundered will eventually go to the warrior who killed the dragon, and the warrior will also receive endless worship and respect from people.

"In the same way, the fight against the demon clan is not only a sacrifice, but also accompanied by rich rewards. So I think that just as humans don't enjoy the gifts of the earth while brazenly saying that they are the guardians of the earth, the vast majority of half-demons also have this self-knowledge.

"And the half-demon society permeates the human society, and it is also a complex river and lake, which is not simpler than the human society. What's more, compared to the general public, half-demons often have an advantage in body and even mind, and it is easier to enjoy wealth, power and status in society. ”

Hearing this, Mu Yun muttered quietly: "I'll just say it......"

Teacher Song was stunned: "What do you say?"

"How can a teacher in a small county town be willing to drive a good car like a crown......" Mu Yun touched the parquet door, and suddenly asked: "By the way, since you are a half-demon, why don't you defend the world, but have the leisure to nest in a small county town as a teacher?"

"As I said, the demon clan rarely appears, and there is no need to fight and kill all day long, so the half-demon doesn't need all the people to be soldiers, and it's much freer than you think. What's more, I'm just a salted fish and a half-demon, and middle school teachers are my main job!"

"What rarely happens...... Isn't that cat demon here up tonight!"

"No, it's just a half-demon, and the real demon clan is not so weak. Teacher Song waved his hand and said.

"What? It's still weak...... Then how powerful are the demon clans you are talking about?" Mu Yun looked shocked.

"Otherwise, do you think that if it is a real demon clan tonight, I will turn around and run away, because even if I rush up with 10,000, I can only give people heads, do you know how to fight?" Teacher Song said, "But you are right, I am really reluctant to rely on the teacher's salary alone, this car was bought by me with the task allowance, and I am a teacher while I also take on tasks to do." Besides, it's just a crown, is it expensive?"

"Zhumen's wine and meat stink, and there are frozen bones on the road, you half-demon who is mixed in human society is so high-profile, and the hidden work is not meticulous enough......" Mu Yun said, "By the way, what you just said is one of the sources of the half-demon, and what is the other?"

Teacher Song was silent for a while, and then said slowly: "In addition to being demonized by the influence of demon qi, there are also some half-demons, which come from the hybrid blood with the demon clan. ”

"What? a hybrid with the demon clan?...... Didn't you say that whether it is a half-demon or a human, they and the demon clan are inseparable enemies?" Mu Yun said.

"Having said that, there has never been a shortage of careerists, whether human or half-demon. Historically, humans and half-demons have exhausted all kinds of methods in order to obtain the powerful power of the demon race. Ancient tribes sacrificed human beings, and medieval witches made contracts with demons at their own expense...... In this way, at any cost, you can get mixed blood with the demon clan, and you will also be a half-demon. However, the half-demon born in this way is often very unstable and more dangerous. ”

Your circle is really messy...... Mu Yun just wanted to complain like this, but when he thought that he was also a half-demon, he didn't say anything. Suddenly, he thought of something, hesitated for a moment, and asked in a low voice, "Then my parents and parents, are they also half-demons?"

Teacher Song was stunned for a moment, as if he didn't expect Mu Yun to ask this question, but he still nodded slowly and said, "Yes, your parents are half-demons. ”

"Do you know them?" Mu Yun asked again, "The two of them...... Is it really gone?"

"I don't know them, but I know them. Because your mom and dad are very good people, and they are very famous among the half-demons. And when you were very young, they died in an accident, but miraculously protected you. Your mom and dad are a great pair of parents. ”

“...... I see, thank you. Mu Yun nodded, then fell silent and did not ask the next question.

Teacher Song didn't say anything more, he looked ahead, listened to the broadcast of the navigation, and fiddled with the steering wheel from time to time.

After a while, the voice of the navigator came again: "...... There are still 100 meters ahead to reach the destination, and this navigation is coming to an end. ”

The car slowly stopped in front of a dimly lit alley.

"Alright, it's time for you. Teacher Song said to Mu Yun, "I feel like we talked a lot tonight." I know you may have a lot of doubts in your mind, but let's get here today. You go back first, and then I'll find an opportunity for us to talk in private. ”

Mu Yun nodded, and reached out to push the car door. Halfway through, it stops again.

"What's wrong?" Teacher Song asked with a smile, "Do you have any other questions?"

"No, there are too many questions to ask," Mu Yun shook his head, "I just remember that I haven't thanked you properly yet." Teacher Song, thank you for saving me today, and thank you for telling me so much!"

"Hehe, you're welcome. ”

"But, you're obviously a physics teacher, shouldn't you be a materialist, but you actually told me a lot of these weird things. How are you going to let me listen to your physics class in the future?"

"Physics is far from the end. What you see may not be true, and legends are not false. Reality is precisely what we don't want to believe but still exists. People born in this era can easily be proud that this is an era of science, but ignore the development of human society to this day, and only peek at the tip of the iceberg of science. Teacher Song said seriously, "...... But that's a long story, so I won't go far. And what happened today, remember not to mention it to others. ”

Mu Yun nodded again and stepped out of the car door.

"Hey, wait a minute!" Teacher Song suddenly shouted.

Mu Yun turned his head and happened to meet Teacher Song's gaze.

"You know what," Teacher Song said, "you're actually very good. ”

Mu Yun was stunned for a moment, and he didn't understand why Teacher Song suddenly praised himself like this, maybe he saw that when he heard the news from his parents just now, his mood became slightly depressed, so he deliberately said this sentence to comfort himself.

Mu Yun touched the back of his head embarrassedly: "Hey, why are you saying this, I'm not a three-year-old child anymore, you don't have to make a special trip to say these comforting words to me!" Then he showed a expression, nodded and patted his chest and said: "And do you still need to say this, of course I know that I am very good!"

"No, I mean, you're better than you think...... And be excellent!" After Mr. Song finished speaking, he waved his hand, "Okay, go home quickly, remember to pay attention to safety on the way." ”

"Okay, then I'll go!"

With that, Mu Yun closed the car door and plunged into the rain.

Teacher Song sat in the car, quietly watching Mu Yun's back disappear into the alley, and suddenly a shallow smile appeared on the corner of his mouth.

He gently took a sip of the hot tea in the thermos cup and said to himself: "Your son, although he looks like his mother, has a personality that is somewhat similar to yours." ”

Immediately, the engine of the car started slowly, accelerated, and drove into the night.
