Volume 2: Residence in the Capital Chapter 102: Courtesy and Sacks
Zhang Shou explained the matter of the second entering the first for a quarter of an hour to the Minister of War Lu Wan, and Lu Sanlang also explained it to Zhu Er for a quarter of an hour. The others around, whether it was Zhu Ying, Mrs. Lu Zhen, Lu Dalang and Lu Erlang, or Jiang Mama and Zhu Hong who had just entered the Lu Mansion and were standing in the courtyard outside the study, all received a deep mathematical education.
And then... nothing happened.
The essence of binary, "every two plus one", takes a while for many modern science scumbags to accept, and they may make mistakes in the initial conversion, not to mention the ancient people who only know liberal arts and people who can simply recognize words. As a result, Zhu Er felt dizzy, Lu Dalang and Lu Erlang felt numb, and Jiang Mama and Zhu Hong exchanged glances, all of them were shocked.
How long has the future son-in-law studied with Master Ge? Not long, right? Is this all from reading those mathematical scriptures?
What kind of brain does one need to learn all this! Master Ge is really amazing. Not only did he get the top seven in the imperial examination, but he is also a master of learning. That's why the disciple of my uncle is so amazing!
My son-in-law is so powerful, only Lu Sanlang can be so powerful!
In the study, in front of the desk, Zhu Ying, who had long been accustomed to hearing countless difficult words burst out of Zhang Shou's mouth, still stood calmly and upright, but her bright eyes looked at the young man beside her from time to time, full of pride and honor - even though she couldn't understand.
But behind the desk, Minister Lu had to cough to interrupt Zhang Shou.
He understood how to convert those horizontal lines into binary; he also understood that he needed to convert these binary numbers into numbers used in daily life; however, he was still confused about how to do this conversion .
"Doctor Zhang, you don't need to say anything. I just want to ask, if Sanlang knows the principle, can he..."
Zhang Shou sneered: "Minister Lu underestimated his son's talent for learning by analogy and applying what he has learned to other situations."
Lu Sanlang outside the door finally couldn't bear to listen to it any longer. He didn't care about the thirty-twenty-one and went straight to push open the door of the study. Then he held his head high and said, "Dad, since the young master has revealed the mystery of those horizontal lines, I can naturally solve it. However, those clerks under you who deal with various military supply figures all day long, as long as they understand the key, there will always be a few who can solve it."
"That's what we call, every profession has its own specialty!"
As he spoke, he raised his head and said with an unprecedentedly tough attitude: "If you hadn't revealed that intention before, I wouldn't have chased after Miss Zhu like a stray dog. Now that I know you are just playing a trick, I will make it clear! I, Lu San, know myself. If you want to arrange another marriage to pretend, please use my elder brother and second brother to make up the number, don't look for me!"
"presumptuous!"
Lu Wan immediately slammed the table and stood up, especially seeing that the passionate Lu Sanlang was frightened, and hid behind Zhang Shou and Zhu Ying without thinking. He was so angry that he felt that his youngest son had finally made a little progress. But at this moment, he saw that his wife Zhen hurriedly came in from behind Lu Sanlang, with a pleading look on her face.
After being married for many years, he still didn't know Zhen's temper? He took a deep breath and finally suppressed his anger. He said listlessly, "Okay, okay, since you have grown up, you can do whatever you want in the future. I won't bother to care about you anymore!"
"Then I will move back to the Imperial College?" Lu Sanlang felt that the clouds had cleared and the sun was shining brightly today, so he poked half of his head out from behind Zhang Shou and asked boldly. But when he saw his father's face turn stern, he quickly retracted his head, but his tone was extremely righteous, "The young master promised me that as long as I get the first place in the exam, I will be the head of the Jiuzhang Hall in the future!"
"Okay, you can live in the Imperial College, but you must come back on your days off!" Zhen Shi agreed before Lu Wan did. She then stole a glance at her husband and saw that he didn't want to talk much. She smiled at Zhang Shou and said, "Doctor Zhang, Sanlang is now in your care. I don't ask him to be very knowledgeable, I just ask him to hold his head high and be calm and confident in the future."
"Madam, your wish will definitely come true." Zhang Shou nodded slightly to Zhen and said with a smile, "When Lu Sanlang becomes the head monk in the future, I will come back and kowtow to you, my mother."
"Okay, as a mother, I would like to thank Dr. Zhang for his kind words!"
Thinking of her youngest son's bright future, Zhen was not only grateful to Zhang Shou, but she also liked Zhu Ying more than before. Since she would not become her daughter-in-law anyway, all the shortcomings of Zhu Ying that she had disliked before now became her strengths.
As an unmarried daughter, she should be cheerful and lively, and it is harmless to be willful and arrogant. Is it necessary to be obedient and dull? Alas, she only gave birth to three sons and one daughter in her life...
So, Zhen took the opportunity to step forward and held Zhu Ying's hand: "Yingying, I have always admired your grandmother. Now that your family is in trouble, you must work with your second brother to be filial to her. Your second brother just had a misunderstanding with Sanlang, which caused a small incident. Since our two families are close friends, let Sanlang and your second brother talk it out..."
Zhu Ying almost subconsciously wanted to shake her hand away - who is your family's friend? Minister Lu is one of the masterminds of the attack on my father! Besides, did you call me by my name? However, Zhu Ying, who was about to explode, found Zhang Shou winking at her. After a moment of hesitation, she gritted her teeth and listened to Zhen's nagging.
When Zhen saw that Zhu Ying no longer walked away in disdain as she did before, her smile deepened. In her heart, she thought a thousand times that the girl with a fiancé finally knew how to treat people.
She withdrew her hand and glimpsed Lu Wan, who was sitting in the main seat with a gloomy face. She stepped forward and said with a smile, "Master, it's so late, why don't you ask Dr. Zhang to stay in the mansion for dinner before leaving?"
He kidnapped your son, and you still want to keep him for dinner?
Lu Wan was almost going crazy with his wife's stupid brain, but he was currently pondering whether the minor official from the Ministry of War could solve the puzzle, and whether it was true or not. He was too lazy to give her a perfunctory answer, and said without hesitation: "Since you like it, then set up a table in your yard and let Sanlang keep you company." As he spoke, he suddenly saw Zhu Er, and he became annoyed again.
It was all about Zhu Gongquan brought by Zhu Er. What secret report, what a serious matter... If that smart guy hadn't informed on him, he wouldn't have recruited Zhang Shou and Zhu Ying into the mansion!
So, Zhu Er, who had just made a scene at the Lu residence and thought he would be kicked out, was invited to the courtyard of Lu's wife Zhen as if in a dream, and enjoyed the good treatment of a close family. Seeing Lu Sanlang smiling as he placed chopsticks, set the table, and poured wine, not to mention serving his mother Zhen to a smile, even Zhang Shou and Zhu Ying were also attentive to him, he couldn't help but feel even more uncomfortable.
If he also knew how to serve his grandmother and the lady-in-waiting like this... maybe he wouldn't be in such a miserable situation at home?
Zhang Shou, Zhu Ying, and even Lu Sanlang didn't notice Zhu Er's self-pity. Because Zhang Shou and Lu Sanlang had stayed up all night, and Zhu Ying had been running around all day, Zhang Shou barely managed to eat half a meal. Unable to resist the sleepiness, he stood up to say goodbye, and by the way, he held down Lu Sanlang who was about to see him off.
"Jiuzhang Hall will be renovated in the next two days. You can go directly to Ge Mansion from now on. I go there often. The teacher is compiling a terminology manual, and he is quite interested in things like secret letter codes." Zhang Shou saw that Lu Sanlang was surprised and happy and agreed repeatedly, and Mrs. Lu Zhen was even happier than Lu Sanlang. He smiled secretly, but didn't notice that someone tugged at the corner of his clothes.
Without looking, Zhang Shou could tell that it was Zhu Ying, and even understood how angry she was at the moment.
We are not here just to save Lu Sanlang. What about the matter about Lu Sanlang's father Lu Wan?
He still didn't turn his head, but said with a double meaning: "Yingying, it's getting late, I'll take you home first. Don't worry, he will come to find us."
Because of this sentence, Zhu Ying was suppressed until she left the Lu residence. After getting on the carriage, she saw Zhang Shou was going to ride a horse, so she leaned out of the carriage window and shouted angrily: "A Shou, can't you explain yourself clearly?"
Zhang Shou was slightly stunned, then he smiled and said a few numbers: "353, 150, 305, 558."
Faced with these four inexplicable numbers, Zhu Ying immediately became suspicious: "What do you mean?"
"The first four sentences of the letter that Lu Sanlang handed over earlier, converted from binary to decimal, are just these four numbers. However, without knowing the code book, and the vast sea of books in the world, Minister Lu will have to rely on a little luck to find the words that correspond to the numbers."
At this point, he smiled and said, "If he is not so lucky, of course he will come to us again. If he is lucky, maybe he will come to us. Because at that time, he may feel that Lu Sanlang's note revealed too much. At that time, we may be able to turn the tables."
Zhu Ying was overjoyed, and then she heard a cold voice: "Master, Miss, where is the sack?"
Zhang Shou recognized Ah Liu's voice and looked over. But when he saw the not-so-tall boy carrying a huge sack, he realized, "Where did he come from?"
Seeing Zhu Ying also leaning on the car window, staring at him curiously, Ah Liu pointed at the gate of the Lu Mansion and said, "I picked it up."
As for how to pick it up, is it worth talking about?
