Of course, Zhang Zixing would not tell his true origin, and replied: "How exquisite is the "Heavenly Calculation" written by today's son, can't it be surpassed by mediocre talents like me? I have been fond of arithmetic since I was a child, but unfortunately I have not been allowed to enter until the advent of "Heavenly Calculation", and I suddenly opened my mouth and realized the true meaning. ”

While explaining the origin, Zhang Zixing's words also quietly praised the son of today (actually boasting), Qing'er smiled and said: "If Mr. is a mediocre talent, then isn't Qing'er a first-class fool?" Mr. has such a great talent, why not serve the court and show what he has learned in his life? My father has a few friends who serve in the court, why don't Qing'er ask my father to introduce him on his behalf?"

Serve the court, help yourself work, forget it, it's better to be the boss...... Zhang Zixing smiled and shook his head: "Miss Qing'er's good intentions are appreciated in my heart." If I force myself to become an official, I am afraid that there will be disasters, and it is better to be a free person now. ”

Seeing his resolute tone, Qing'er couldn't help but show regret, and sighed: "Mr. is really a quiet person! Qing'er is brave, and there is a reluctant request." The people who listened to the grass hall that Mr. said today were all ordinary people who liked arithmetic, and they had no good teacher to guide them. Qing'er is shallow in learning, but also has the courage to teach ugly, Mr. is highly talented, if you can teach them one or two, you will be able to benefit them for a lifetime, and I hope that Mr. will not shirk. ”

Zhang Zixing knew that she would ask like this, and said: "Listening to the young lady's lecture today, she is articulate and clear, which makes Zixing admire her very much. Although I have little knowledge in my heart, I don't have the eloquence of a young lady, and I am afraid that I will get half the result if I start speaking rashly. Why don't I pass on my experience to Miss one by one when I have time, and then pass it on to the students after the Miss understands it?"

Qing'er didn't know if this was his excuse, and thought that she could often ask this clever gentleman for advice, so she didn't persuade him more. Zhang Zixing then discussed some problems in teaching with her, and said the educational theories of later generations, Qing'er Bingxue was smart, knowing that he was teaching his own education method, so he didn't care about admiring it, and quickly memorized it with his heart.

When the two talked for a long time, Zhang Zixing did not ask Qing'er to return the book as agreed, as if there was some kind of tacit understanding, and Qing'er, who had a good memory, seemed to have forgotten about it.

"Speaking of which, Miss and I don't know each other, by the way, why don't you see Sister Ling today?" Zhang Zixing asked intentionally or unintentionally.

"That sister is the daughter of my father's close friend, so she happened to come to see me, and left a few days later. Qing'er's eyes flashed, and she asked in a casual tone, "Sir seems to care a lot about my sister?"

"Where! Although that young lady is young, her martial arts skills are very amazing, and my guards are quite strong, and ordinary strong men can't get close, but they can't beat her, so I have a deep impression of her. ”

"My sister is also quite concerned about the wicked image of Mr. 'bullying others', and she even said afterwards that she would teach Mr. a lesson! Fortunately, Mr. is lazy, so he didn't come to the cottage for a few days, otherwise he would ......" Qing'er remembered a few cruel words said by the woman in the green shirt after returning home that time, and couldn't help but hide her face and smile: "Qing'er believes that Mr. will not do things that oppress and do good things, and now he has the grace of guidance, and he will mediate from it in the future, so that my sister will change her impression of you, and I hope that Mr. will often come to the cottage for advice." ”

Zhang Zixing secretly embarrassed: This Qing'er is too smart, he seems to have seen his intentions for that beautiful girl, and he also faintly put forward the condition of "pulling the strings". Although he was seen through his heart, fortunately, he was quite thick-skinned, and his face remained unchanged and said: "The last incident was purely a misunderstanding, in fact, I see that she is also very familiar, and she seems to be an old friend, but unfortunately I didn't have time to ask, can Miss Qing'er reveal a word or two about the origin of that young lady?"

"Oh, after the deceased?" Qing'er showed a playful look in her eyes, and deliberately asked: "I see, may I ask the old man's name?"

Zhang Zixing wanted to determine whether the woman was Deng Chanyu, and said: "My old man's surname is Deng, I haven't seen him for many years, I don't know if I can say it wrong?"

"Sir, don't be anxious, my sister may come to the song again next month," Qing'er's eyes flickered, and she didn't answer directly: "I will introduce Mr. at that time, why don't Mr. ask yourself?"

Zhang Zixing knew that he couldn't get anything out of the mouth of this smart woman, so he laughed and stood up: "Miss is really wonderful! It is Zixing's luck to know Miss." At this time, it was getting late, Zixing said goodbye first, and he would come to the cottage again to disturb him in three days, and hoped that Miss would stop asking someone to drive me away. ”

Qing'er hurriedly saluted: "Mr. said it was funny! With Mr.'s skills, even if he doesn't leave, Qing'er can't do anything." ”

The two looked at each other and smiled, and when they parted, Qing'er saw the stars outside the house, and only then did she realize that she had unknowingly chatted with this Mr. Zixing for three hours.

"A thousand glass......es of wine for a confidant," Qing'er whispered to herself the "famous words" Zhang Zixing said, looking at his distant back, with a brilliant look in his eyes.

After a few days.

"Bang, bang, bang!" There was a crisp sound from time to time in the forbidden place in the eastern corner of the imperial city. The so-called forbidden place is a secret place that no one can enter without the permission of the Son of Heaven, not even the queen mother.

In the stone chamber of the forbidden land, Zhang Zixing, who was the son of a great merchant, was disheveled, lying on the ground without the honor of a king, panting heavily, his hair was soaked with sweat, and beside him, broken glass and iron frames were poured horizontally and vertically.

Zhang Zixing looked at his hands that were almost unconscious, still spasmodic, and a nameless fire ignited in his heart, he gritted his teeth and sat up, and kicked on the iron frame, how powerful this kick was, the hard iron frame was suddenly deformed, flew out far away, and "Ding Chang" fell to the ground. He still couldn't get rid of his hatred, and he smashed the glass on the ground again, and then the whole thing seemed to be out of strength, and he fell to the sky.

"Failed again!" The anger in Zhang Zixing's eyes gradually disappeared, replaced by a look of despair, and the successive experimental failures during this period of time made him depressed.

In fact, the speed of the advent of glass has been thought to be fast, mainly thanks to the manufacturing plan of Superbrain, which was formulated by Superbrain according to the actual situation of the existing materials and process level of the Shang Dynasty, which is very effective, and it was successfully "invented" glass in just three days, which also made Zhang Zixing very happy. However, the main purpose of glass - the manufacture of super Leyden bottles is difficult, not because Zhang Zixing's idea is problematic, but because the conditions are too restricted, the required materials (especially metal) can not be found in the whole country, and there is a lack of modern test equipment, so the design scheme can only be changed again and again according to the existing materials, and the final production of Super Leyden bottles can not meet the requirements at all, he also considered using metal and insulating materials to make capacitors, but the effect is worse.

The amount of energy that these capacitors can store is much lower than expected, and when it is finally fed into the body, the energy obtained by the superbrain is pitiful, and its body can hardly withstand the repeated torture of electric shock. According to Superbrain's analysis, at this rate of infusion of electrical energy, even if it is a thunderstorm every day and continuous input every night, it will take hundreds of years to reach the level of getting it out of trouble. He also considered using the spells of cultivators such as Wen Zhong to artificially create lightning strikes, but first, the power was far less than that of natural thunder and lightning, and secondly, it would expose the biggest secret of the super brain, even if he didn't worry about this, he could use external forces to make enough thunder and lightning energy enter successfully at one time, and Zhang Zixing himself would also have a considerable danger to his life, how could this not make him frustrated.

Failure is failure, Zhang Zixing is by no means a person who gives up lightly, so he did not lose his fighting spirit, but the desire to conquer difficulties in his heart is even stronger - he can be unique in the scientific community of the 24th century, which is full of wise men, and it is by no means a fluke, in addition to his extraordinary talent and enlightenment, doubling his diligence and indomitable fighting spirit are also the key to success.

After Zhang Zixing vented the frustration in his heart, he finally stood up, he was experienced, and he knew that he was no longer suitable for experimenting today, and he had to adjust his mood and try again after thinking and calculating calmly.

He walked out of the forbidden place, bathed and changed clothes, and then left the palace again and walked in the direction of the thatched hall.

Tanwei grass hall is a lecture every three days, and there are guards at the door, and idlers are not allowed to enter. Zhang Zixing recently said that he had been coming and going frequently in the grass hall and was very familiar with the guards, so everyone did not stop him, but respectfully invited him into the grass hall.

Qing'er is still plain and masked, and she looks like a mysterious beauty. She hadn't seen Zhang Zixing for a few days, and she was very happy to see him arrive today. After Zhang Zixing sat down, Qing'er, as usual, took out the difficulties she had encountered in the past few days to ask Zhang Zixing for advice. Although Zhang Zixing's mood has not improved because of the failure of the experiment, she did not show it in front of Qing'er, but patiently answered the problem for her.

Suddenly, Qing'er stopped asking questions, ordered someone to send pastries and fruits, and invited Zhang Zixing to taste them, she didn't continue to ask, but chatted with him casually.

Zhang Zixing felt a little strange, Qing'er usually wouldn't chat with him like this, so he couldn't help asking: "Miss Qing'er's question today seems to be unfinished, why is there a sudden conversation?"

Qing'er replied softly: "Mr. Guan seems to be preoccupied, so he can't bear to disturb him, may I ask if Mr. has encountered anything unsatisfactory?"

Zhang Zixing didn't expect Qing'er to feel so keen, although her appearance was as usual, she had already noticed the boredom in her heart. In fact, since he ascended the throne as the Son of Heaven, he has worked hard to bring forth the new, and his martial arts have all been perfect, and he seems to be really like a perfect saint recited by the people. But in fact, he also has times of failure, times of fatigue, and times of being affected by various negative emotions, because he is a human after all, an ordinary human with seven emotions and six desires.

In the past, when Zhang Zixing was in a bad mood, he liked to find a confidant and friend to talk to. But since he came into this world, he has countless subordinates, four wives, and none of his friends. As the Son of Heaven, he is really a veritable "lonely man," and it is no wonder that in this era, who dares to have a relationship with the Son of Heaven regardless of the courtesy of the monarch and his ministers? His four wives are deeply affected by the great environment of male superiority and inferiority of women and the supremacy of monarchy, and no matter how hard he tries, he will never be able to change their awe-inspiring mentality, even Huang Feiyan, who has an extraordinarily long surname, and Yueji, who has a strong surname, are no exception.

The Qing'er in front of her is generous, demure, and empathetic, with a high IQ and talent, although Zhang Zixing has not seen her true face so far, there is a faint feeling of a confidant and friend in her heart. Thousands of gold are easy to get, confidants are hard to find, and confidants are even more difficult to find.

Today, when he was in a depressed mood, he didn't choose to go back to the palace, but subconsciously came here, perhaps because of this confidant.
