When Baozi finished writing half of the blackboard, an extremely complex physics problem was easily solved. The students in the audience sighed for a while, and Baozi turned around, what he gained was the admiration and envy of everyone, as well as the complicated look in Roland's big watery eyes.

Lee Jae-yeon is a careful friend, and he selects the ghosts of several outstanding scholars in the underworld for Baozi as teachers, and adds make-up lessons to Baozi on weekends and after school. This group of teachers is very hard-working, not because they are afraid of the current manager Li Zaiyuan, but because they themselves are extremely serious and responsible scholars, and the days of becoming ghosts make it difficult for them to live, and they are suddenly in charge of the whip again, of course, they are all in good spirits, although there is only one student, no, there is Xiao Yi occasionally.

Baozi is humble and low-key, and treats teachers with great respect, coupled with his intelligence, not only the school's homework is completed well, but the teachers' meals can also be done on time. Teachers have a characteristic, they like students who love to learn, and teachers naturally can't put down students like Baozi, and they can't wait to open their brains and pour the knowledge they can teach. This efficient teaching allowed Baozi to complete all the high school courses ahead of schedule, and even dabbled a lot in college courses. Li Zaiyuan once said half-jokingly and not without regret, "Leibniz, Einstein, and Marie Curie have all been reincarnated, even if there is only one left for me, I will invite him to be your teacher." ”

At this time, Baozi would also smile and quip, "Even if you don't come, people are in the jurisdiction of Beiju Luzhou, and they have their own underworld, so you don't want to come." ”

Of course, Li Zaiyuan knew how difficult it was to transfer people across departments, but he was occasionally interested in the underworld of Beiju Luzhou, and he had heard a missionary who died in the provincial capital talk about the so-called civil law system and the law of the sea system, and he felt that the law enforcement of the underworld was more fair and perfect than his own underworld, and he was bent on reforming it. Baozi told him that the underworld in Beiju Luzhou is called "hell", the local pronunciation is hell, divided into purgatory (purgatory) and hell two levels, according to legend, the hell and heaven there are relatively large, can fit everyone, so people do not reincarnate a word, nor Meng Po poured decoction, after death, immediately diversion, good people go to heaven, bad people go to hell, bad people die and put them in purgatory to burn, burn almost eliminate the sins, and then go to heaven. This clear mode of thinking has given rise to a relatively complete modern legal system in Beiju Luzhou.

In addition to science and engineering, Li Zaiyuan found the help of the ghosts of many experts, and the teaching methods of many history courses are more interesting, Baozi always can't remember the battle history of the Taiping Heavenly Kingdom, so the underworld sent a few old Taiping soldiers to chat with Baozi about the war history; Baozi couldn't remember the so-called germination of capitalism in the Ming and Qing dynasties, so the underworld sent the big businessmen at that time to talk about the history of the red-topped businessmen of that year. Over time, Baozi turned out to be an expert in history, because his views on history were based on chatting with the ghosts who had experienced it, which was naturally very real. There were a few times about the stories related to the fifteenth year of Wanli, which made Luo Xiurong dumbfounded.

With a little leisure, Baozi sat on the north mountain, looking at the tomb and the complex, and studying the way to break it. What secrets are buried in this three-regardless zone located under the land of the division? Roland will sit quietly next to the bun at this time, looking at English calmly, she likes this feeling, there is such a quiet and clean person around her, she can rely on, and she is not noisy, she is willing to sit like this for the rest of her life. Roland likes the temperament of the bun, confident, healthy, easy-going, sunny, this person is inconspicuous in the pile, not the kind that can be seen at a glance, but has a very chewy taste. If the first time I had a good impression of steamed buns was in Ludingshan Yonghe Supply and Marketing Cooperative, the seeds of this love have been buried for four years. After she returned to the provincial capital, she almost always missed the buns, and when she heard Luo Xiurong personally say that she was going to take the buns to school, she almost lost her temper happily, which made her sister Luo Pei deeply puzzled.

"Roland" Baozi never uses a nickname to call this petite beauty around him, which is different from his title of "Huahua": "You say, why are these Japanese wizards deliberately ambushing so many things, and there are so many loyal dead soldiers who have persevered to defend and execute until now?" ”

"Because of desire." Roland replied lightly, "My dad said that from the natural world to the human world, it is desire that sustains their development, and babies are born looking for **, and they don't care whether their mother is weak or not." Men do business in order to accumulate resources and show their abilities in order to show their abilities. When a state is established, it expands and occupies territory at any cost. The state and the baby, in fact, are the same. ”

"Why don't I have such desires" Baozi looked at himself, always feeling that he was living a simple and chaotic life, lacking interest and desire in everything. The only time when Baozi felt that he had a sense of control was when he was in the third class of Luding Mountain, when he was in charge, holding the wind and thunder in his hand, surrounded by all the immortals around him, and quickly stepping on the green hill. And since Lu Dingshan came back, he has become an ordinary Bao Ziqiang again. Baozi has been troubled by the separation of identity, he is an ordinary student during the day, and he is the god who leads the meeting of the Three Realms at night, this contrast and tearing makes him confused, the fairy world is much higher than the human world, since he has boundless ability, why is he still an ordinary person in the human world, and even the recognized mental illness in Dafang Town, it is much more difficult to mix in the human world than in the fairy world. And whether all this is a Zhuang Zhou dream, which is reality and which is illusory, it is impossible to distinguish at all.

"Because you are a god, you are not a second-grade immortal like you" Roland replied with a small straw stick, and the breeze came slowly, sending a faint fragrance from Roland's body into Baozi's nostrils, and the olfactory nerve immediately reported to the brain after the olfactory nerve response, and the brain instinctively told Baozi to "press her." ”

Baozi shook his head, "Maybe I'm afraid to face some things." ”

Roland listens to him so well that his auditory nerves are as sensitive as they submit information to his brain for analysis, and his brain still instinctively tells Roland, "You go and knock him down!" But Roland's facial expressions seem to ignore the judgment of the brain, they are independent information analysis agencies, and their chief officer is called consciousness. But consciousness tells Roland, "You're a girl, you have to lead but not provoke." This order, which was more complicated than the original idea, was carried out, so Roland ignored Baozi's words, took out a piece of paper full of words, folded a paper airplane, and wanted to fly out from the top of the mountain.

Baozi asked, "This is a letter, how can you say throw it away?"

Roland wanted him to see it, and was busy saying the lines prepared in advance, "Shi Mingli wrote it, two letters a day, and I was annoyed to death." As he spoke, he threw it gently, and the paper airplane drew a beautiful arc in the blue sky, spinning and flying in the direction of the ghost building.

Roland tilted his head to look at Baozi's expression. Baozi just drooped his eyelids and fiddled with a leaf, "You can't waste other people's active input." ”

"Okay, I'll promise him," Roland took a step.

"Of course, you have to consider whether it is suitable for you," Baozi had to take a step back.

"Hypocrisy" Roland threw off a sentence and went down the mountain alone, her ponytail trembling rhythmically with her footsteps, conveying her arrogant and self-reliant personality, she is another gentle version of the cabbage flower.

"Bao Ziqiang!" Roland, who had gone far away, shouted to the buns on the mountain

"What's wrong?"

"If you don't like it, I can just say it." Roland is very straightforward.

Baozi was silent.

"Is that like me?"

Baozi was still silent.

"Hypocrisy!" Roland yelled at the buns.

Baozi didn't respond to Roland's words, his eyes were staring straight at the plane made of letterhead, it was still flying! And it wasn't the usual spiral curve falling, but it was dragged by a mysterious air current, flying straight towards the ghost building! The flight distance and route are impossible for a small paper airplane to do. What kind of power is near the ghost building? Baozi looked up at the birds in the sky, and they were also interested in avoiding the ghost building area. There is a huge energy field here.

Baozi decided to visit the ghost building at night again. This time, he did not act rashly, but hurriedly caught up with Luo Lan and went to find Luo Xiurong together. Roland thought that Baozi was expressing his response to his shouting with practical actions, so he was naturally full of joy, and immediately put away his attitude of breaking with Baozi, and happily took Baozi to his father.

Luo Xiurong is busy at home, he lowered his head and soldered a circuit board with an electric welder in his hand, the small desk is full of all kinds of metal parts and a large number of reference materials, and in the center of the table is placed a jade surface device similar to half a Taiji diagram, in which 10 high-strength wires with plastic insulation are erected on the pillars in parallel through insulators. Some of these wires are field wires, some are induction wires, and one field wire and one induction wire are installed close together to form a group.

Baozi asked, "What is this?" ”

Professor Luo was immersed in it and did not look up as a "ghost detector"

Baozi noticed that there was a pointer on the shell of the instrument, which marked a clear scale value, and according to the scale from small to large, the words "ghosts, ghosts, immortals, gods" and other words were written in order, "Do you use this to detect the existence of ghosts?" ”

"Yes, but at the moment I've only made one. If you want to detect ghost buildings, you need to install a lot of them so that you can find out where they came from and what the path is. ”

"How does your machine work?"

"Quite simply, if we think of supernatural beings as magnetic fields, then we can find them in a relevant way."

Luo Xiurong believes that the relationship between ghosts and bodies is like the relationship between electromagnetic waves and walkie-talkies. In his view, a ghost is a magnetic field signal that is detached from the walkie-talkie but still exists, that is, a magnetic field with memory.

Human beings are divided into two parts: the physical body and the ghost, the body serves the ghost, and the ghost depends on the body and is indispensable to each other. When the fetus is in the mother's body, the first three months of the original spirit is very weak, and it can even be said that there are no ghosts, when the fetus is three months later, the brain gradually develops, blood circulation increases, and ghosts are gradually formed. The body of a newborn baby is a weak magnetic field, and the frequency is the same as that of ghosts, so many children will see ghosts, not with their eyes, but with their own ghosts to communicate with the spirits outside.

With the growth of the human body, the ghost is gradually closely integrated with the body, all the memories of the person are stored by the ghost, and the brain plays the role of a medium. When a person's organs are damaged or the body is weak and aging and cannot produce enough energy, the ghost detaches from the body, and the body dies before the ghost leaves the body. Ghosts continue to exist after leaving the body, and they may be received by individual bodies that have the same properties as their original body, which is what people call ghost possession, and these people who are possessed by ghosts will be given information about the original ghost body.

Since the ghost is a magnetic field, it will be shattered when it encounters a powerful magnetic field, such as the powerful magnetic field generated by lightning. Therefore, it is difficult for many ghosts to survive on their own, and a thunderstorm may destroy many spirits. And the energy of the ghost is very strong, and it can actively dodge the energy attacks of the natural world.

"So, how does this device work?" Baozi asked

"It's low-frequency signal detection. There is a low-frequency signal oscillator, which generates a low-frequency oscillating signal voltage with a frequency of 1-40kHz, which is sent to each field line, and a magnetic field is generated around the field line. Then connect the induction wire with the alarm controller. If a weak magnetic field that meets the conditions of the band range moves, the electromagnetic field in the detection area will be disturbed, so that the inductive voltage output by the induction line will change, and the ghost can be locked as long as the amplitude and rate of signal change or the duration of the interference are measured."

To tell the truth, Baozi didn't understand too much, but he felt that he could try, so he said that he wanted to explore the ghost building again. Luo Xiurong nodded, Detecting this ghost building is also my idea in the past two years, I originally wanted to do it with Li Ruchang, but I didn't expect him to pass away a few days ago, and now there is really a shortage of manpower, I hope Baozi will join in.

Baozi didn't say that Mr. Li Ruchang's ghost was happily serving as his extracurricular teacher, but he continued to deduce along Luo Xiurong's train of thought, and Baozi said, "If we expand the function of this machine, for example, to add an attack function, what do you say?" ”

"Bun, what do you think?" Luo Xiurong's eyes lit up.

"Didn't you say that when there is a phenomenon such as thunder and lightning, it will naturally destroy a large number of ghosts?"

"Yes, in addition to thunder and lightning, there are now more and more high-voltage power lines, electric railways and other giant point devices that can destroy ghosts."

"Wouldn't we be able to create a detection and assault weapon by fitting some of the devices with high-voltage discharge devices?"

"Makes sense. Indeed, you have fought against ghosts, and you have a very heavy desire to kill, and I, an old man, have never dared to think about it. ”

"There's no way, some ghosts don't have good things in their heads, they exist in the world to harm people and kill people, it's better to break them up."

"Yes, the root of the evil of ghosts is the immortality of the human heart"

Baozi thought for a while and continued, "This device should be a directional discharge and precision strike, because the people in the fairy world and the underworld are also afraid of this kind of high-voltage electricity. ”
