"Young master, it's not good!"

South of Chang'an City, the backyard of the Lin family.

The maid Xiaoshi ran into the study with the latest issue of "Datang Daily - Dahua Jianghu" and said to Lin Hao, who was sitting in front of the bookcase to review his homework.

"What's wrong? What's wrong? Don't bother me with small things! ”

Since the beginning of the year, Lin Hao has been preparing for the exam in retreat, although he knew that Pi Xia Ke had opened a new book, but in order to be admitted to Yanhuang Academy this year, he could only endure the pain and cut his love, and put "Zhu Xian" aside for the time being, he planned to wait for the exam to finish the test and then watch it together!

Several of his maids got his order to buy a copy of "Dahua Jianghu" every day, cut out the part about "Zhu Xian" in it, bound it into a book, and kept it for him to read after the exam.

"Young Master! In today's finale of "Zhu Xian", Pi Xia Ke said in the back that he would completely seal his pen and stop writing in the future~! The office of "Datang Daily" in Chang'an City gathered a lot of readers, all of whom were frantically rewarding and begging Pi Xia Ke not to close the pen! ”

Xiao Shi took the latest issue of "Big Talk Jianghu" and said breathlessly.

"What? "Zhu Xian" is coming to an end? Is the leather knight going to seal the pen? ”

When Lin Hao heard this, he stood up in shock, he originally planned to raise "Zhu Xian" first, but he never expected that this cultivation would directly raise the author! This level of book raising, it is estimated that it will be difficult for anyone to surpass it in the future, right?

"Uh-huh! Young master, look! ”

Xiao Shi nodded in response, and handed the "Big Talk Jianghu" in his hand to Lin Hao.

Lin Hao took it, read the last paragraph above seriously, and finally couldn't help but sigh: "Alas! Pity! What a pity! I'll never see him write again! Xiaoshi, you go and get a thousand Tang Yuan and reward it to Pi Xiake! ”

Now the bicycles of the Yanhuang Chamber of Commerce have been sold well all over the country, Lin Wenyuan has made a lot of money by virtue of his membership of the Chamber of Commerce, and Lin Hao has been preparing for the exam in retreat recently, and there is very little place to get money, so this kid has also saved a lot of private money, and he can still afford a thousand Tang yuan!

"Yes! Master! ”

.......................

"Brother Qingque, Brother Xiaoxuan really doesn't plan to write in the future?"

In the palace, the little fat man just said hello from Empress Changsun, and was "robbed" by Changle, Changle pulled Li Tai to the garden and asked urgently.

Li Tai sighed and said helplessly: "I just knew about this!" Although I feel uncomfortable, I understand that the mountain chief, he has so many things on weekdays, how can he have time to write! We should have been mentally prepared for this result! ”

When Changle heard this, a trace of sadness appeared on her face, and after a while, she nodded and said, "Hmm! Brother Qingque, you are right, Brother Xiaoxuan can't always write for us, he is now not only in charge of Yanhuang Academy, but also in charge of the huge fiefdom of Lantian County, he should stop writing~! It's just that from now on, it will be difficult to see such a wonderful thing as "Zhu Xian"! ”

.....................

"Mountain Chief, are you really going to close your pen and stop writing?"

Inside the new workshop of the Wonder Pavilion.

Li Zexuan came here today to inspect the progress of technological transformation and upgrading, and unfortunately met Ma Zhou, who took Li Zexuan to a corner and asked with a sad face.

"Alas! Don't write it! Don't write it! Ben Hou is getting busier and busier now, where can I have time to write again! ”

Li Zexuan waved his hand and said with a wry smile.

Ma Zhou said unwillingly: "But, Master Hou, are you really willing to be your readers?" Do you know that this morning, in Chang'an City and more than 20 prefectures and counties around Chang'an City, countless readers of "Zhu Xian" went to the office of "Datang Daily" to reward you, and they want to apologize for the previous big trouble in the workshop and keep you in this way! Are you really willing to do it? ”

Although he had already decided to close his pen after writing "Zhu Xian", but now that he heard Ma Zhou talk about this, Li Zexuan's heart couldn't help but feel a little uncomfortable, it was a kind of reluctance.

"There is no banquet in the world, there are more and more affairs on Benhou's body, it is impossible to write it all the time, the long pain is better than the short pain, while they are still "not deep", I can withdraw as soon as possible! Besides, the back waves of the Yangtze River push the front waves, and now Hua Hongyi's "Dream Back to Daqin" is gaining momentum, and it has every chance to replace the first position of "Zhu Xian". After the fact, I have hidden my merit and fame, and I am now retreating bravely, not only to make way for young people, but also to avoid being surpassed by others in the future and appear embarrassed! ”

After a moment of silence, Li Zexuan shook his head and said.

Ma Zhou glanced at Li Zexuan deeply and said, "After the matter, go to the clothes, hide your merits and fame, Hou Ye is so literate!" Although what you said is very reasonable, Ma doesn't believe a word! The status of "Zhu Xian", whether it was before or in the future, absolutely no one can shake it! "Dream Back to Daqin" is getting more and more exciting after the revival, but compared with "Zhu Xian", it is still a little worse! ”

After Li Zexuan told Hua Hongyi about the TV series "Myth" in his previous life last time, Hua Hongyi stopped for a week and replanned the outline, and the "Dream Back to Daqin" after the resumption is undoubtedly more exciting in terms of plot!

Engineering student Hua Ziyu, Princess Tu'an Guoyu, Western Chu overlord Xiang Yu, Surabaya Pavilion Chief Liu Bang, Great Qin General Meng Yi, Great Eunuch Zhao Gao, Grand Prince Fusu, Second Prince Hu Hai, Ninety-Five Supreme Qin Shi Huang, these characters collided with dazzling sparks under Hua Hongyi's pen!

Especially the fragment of the protagonist Hua Ziyu in the book using engineering to do things in the Qin Dynasty, readers are all addicted and can't stop!

It is precisely because of this that the results of "Dream Back to Daqin" are getting better and better, and even faintly surpassing "Zhu Xian"! Nowadays, there are more and more imitations of "Dream Back to Daqin", such as "Dream Back to the Three Kingdoms", "Dream Back to the Han" and the like, basically imitating the protagonist of "Dream Back to Daqin" dreaming back to the previous dynasty, it can be said that "Dream Back to Daqin" can be regarded as creating a precedent for the genre of "crossing history"!

Seeing that "Dream Back to Daqin" is becoming more and more popular, Li Zexuan can be regarded as relieved to completely close his pen.

After listening to Ma Zhou's words, Li Zexuan said helplessly: "Hehe! Brother Ma really looks up to Ben Hou, but the matter has come to this point, Ben Hou will not write anymore no matter what, in the future, Brother Ma will have to explore some potential new talents! ”

Ma Zhou saw that Li Zexuan had made up his mind, so he could only sigh helplessly, shook it, and walked away with his hands behind his back.

Li Zexuan stood quietly in place, looking at Ma Zhou's departing back, and after a while, he turned around and walked towards Mo Lingwei's laboratory.

"Xiao Ningzi, come over and help wrap the coil around the magnet!"

"Oooh! It's coming, it's coming! ”

"Hey! Can you stop shaking your hands! Seriously! ”

"I... I didn't shake! It's that it's going to shake on its own, and I can't control it! ”

"You can't control your hands, who can?"

"It's not..."

As soon as he walked to the door of the laboratory, he heard the quarrel between the two rivals, Li Zexuan couldn't help but shake his head and pushed the door in.

"Ahem~! Miss Mo, Shaoning, are you assembling an electric motor? ”

At this time, because they were assembling the motor together, the heads of Yan Shaoning and Mo Lingwei were only less than a centimeter apart, and they looked very ambiguous, Li Zexuan couldn't help coughing lightly, pretending not to see it, and said.

Hearing the sound, Mo Lingwei hurriedly bounced away from Yan Shaoning's side as if she had been electrocuted, a flush quickly appeared on her cheeks, she twisted her hands together, and hurriedly said, "Mountain... Mountain Chief, you're here! Oh, that motor I... I'm going to get it done, and I'll be able to hand it over to you tomorrow at the latest! ”

"So fast!"

Li Zexuan looked at the motor shell and various parts scattered all over the place, and he nodded with great satisfaction and said: "Miss Mo's attainments in electrical machinery are really getting more and more perfect!" Although the principle of this motor is simple, it is not simple at all, and Miss Mo can build it in just five days, which is really admirable! ”

Hearing Li Zexuan's praise, Mo Lingwei couldn't help but be overjoyed, but she thought that she was a professor of Yanhuang Academy and should be reserved, so she hurriedly restrained the smile on her face and said: "Mountain Chief, you have drawn all the drawings of this motor, I just need to do it according to the drawings, most of the credit is on you, I don't dare to take credit!" ”

"Hey! Our professor of Mo University is so humble~! ”

Li Zexuan couldn't help but laugh.

Yan Shaoning on the side was dissatisfied, "Eh~? Shan Chang, this motor also has my credit! Why are you ignoring me? ”

Li Zexuan waved his hand and said, "Okay, okay!" All credit is given! When this motor is ready, I'll give each of you a good thing! ”

Yan Shaoning was suddenly happy, and was about to ask Li Zexuan what good things he wanted to give them, when Song Xiaosi's voice suddenly came from outside the door: "Young Master Yan, the servants of the Yan Mansion came to deliver a message, saying that Yan Shangshu asked you to go home today!" ”

Yan Shaoning was stunned for a moment, he went over and opened the door of the laboratory, looked at Song Xiaosi and asked, "Xiaosi, my father asked me to go back?" So what is the matter with him? ”

Song Xiaosi saw that there was still Li Zexuan in the house, he first saluted Li Zexuan, and then replied: "Young Master Yan, this Xiaosi is not clear, the servant in your house looks very anxious, do you want to go out and have a look?" ”

When Yan Shaoning heard this, he subconsciously thought that something was really wrong with the Yan family, so he hurriedly turned his head and said, "Mountain Chief, Wei'er, then I'll go home first today~!" ”

Mo Lingwei waved her hand and said, "Hmm! Go ahead! ”

Li Zexuan also nodded, and in his heart he secretly guessed that it should be the words he said to Yan Lide yesterday that worked, and the old Yan family was going to propose to the Mo family!

As soon as the words fell, Yan Shaoning hurriedly walked out of the laboratory.

"Oh! That's right! Mountain Chief! There seems to be something wrong with Mr. Wang's side, do you want to go over and take a look~? ”

After Yan Shaoning left, Mo Lingwei was silent for a moment, and then suddenly spoke.

Li Zexuan was stunned for a moment, and said suspiciously: "Mr. Wang? What's wrong with him? ”

Mo Lingwei replied: "Didn't you ask Mr. Wang to set up a workshop for electrolytic refining of copper before, but later Mr. Wang reacted that the electricity generated by our hydropower station is alternating current, and electrolytic refining copper requires direct current, so if the electrolysis workshop wants to operate normally, it can only be through the lead-acid battery you made earlier!"

But the lead-acid battery still needs to be charged after the power is used up, and it must also be charged with direct current, so ah Shanchang, the problem is difficult here, we must get a sustainable direct current out! ”

"I see!"

When Li Zexuan heard this, he couldn't help but suddenly realize that he only cared about making batteries before, but ignored the problem of battery charging, when the battery is discharged, it is to convert chemical energy into electrical energy, and when it is charged, it is to convert electrical energy into chemical energy, and the electric energy mentioned here is direct current, not alternating current, in the previous life, the charger of the lead-acid battery played the role of rectifying the alternating current into direct current and stabilizing the voltage, and now, there is no ready-made charger around him!

"That's right! Mountain Chief! This problem must be solved as soon as possible! Otherwise, our electrolysis workshop will be difficult to move an inch! ”

At this time, Wang Ji's voice suddenly came from outside the door.

But it was Wang Ji who heard that Li Zexuan had come to the workshop, he hurriedly came to Li Zexuan for help, and as soon as he arrived at the door, he heard Mo Lingwei tell Li Zexuan about the problems he was encountering now, so he couldn't help but push the door and enter, saying.

"Huh! Mr. Wang, you're here too~! ”

Li Zexuan came back to his senses, looked at Wang Ji and greeted.

"Hmmm! Wang heard that the mountain chief was here, so he looked for it! Mountain chief, can you solve the problem of direct current? ”

Wang Ji nodded, and then cut to the chase with an anxious face.

Mo Lingwei also set her eyes on Li Zexuan, and in her impression, it seemed that there was nothing that could help Li Zexuan.

Li Zexuan frowned, pondered for a moment, and said, "There are two ways to solve this problem!" The first is to build a DC generator that converts water directly into direct current, and then connects it to the electrolysis workshop of the workshop! ”

"DC generators? Shanchang, how can there be a DC generator? Can this thing be made? ”

When Mo Lingwei heard this, she couldn't help but be surprised.

"Of course you can make it!"

Li Zexuan smiled slightly, he took a pen and paper from the table next to him, and explained while writing and drawing:

"The reason why the alternator is alternating current is mainly because its rotor winding rotates and cuts the magnetic field line, every 180 degrees of space angle, the direction of the current in the winding will change in the opposite direction once, that is, it changes twice in one cycle, and the current of this change is drawn out through the whole slip ring and the carbon brush, because the law of change is sinusoidal, so it emits sinusoidal alternating current.

When we disconnect the middle of the slip rings of the generator and insulate each other, when the rotor windings rotate and cut the magnetic field lines, every 180 degrees of space angle, the current direction of the winding output will always make one end of the output always positive, and the other end will always be negative, so that the output is direct current! ”

After the words fell, the internal core structure diagram of the DC generator had already been revealed on the blank paper, Mo Lingwei looked at it for a while, and nodded: "I understand!" Yamaga, your design is really clever! Huh! By the way, Shan Chief, you just said that there are two methods, but what about another way? ”
