Wang Lei said confidently and slowly: "Mr. Yuan Zhuo has already said the final result. If I say it again, the result is obviously meaningless. Since I prepare this, I will tell you how to answer this question."

"Prepare pen and paper"

Zheng Xuan ordered to stand up and said, "My friend, I will sit here and see how you calculate it."

Wang Lei got up and walked to Zheng Xuan's side and sat down with no choice.

Xun Chen stared wide and his heart was beating constantly, and his heart was beating faster. He thought it was difficult to end. Xun Chen was anxious, but Wang Lei was confident. Xun Chen could only wait and see.

Soon, Shutong brought a pen, ink, paper and inkstone on the stone table.

Wang Lei took the brush and wrote:

Solution: If there is x lamp on the top floor of the tower, you can make the equation:

x+2x+4x+8x+16x+32x+64x=381

Solution to x=3

A very simple solution to the equation directly leads to the final answer

However, Wang Lei could understand this equation Zheng Xuan, Liu Hong, Xu Yue and Xun Chen who was sitting next to him were confused and didn't understand what was going on, especially the strange symbols written by Wang Lei made several people inexplicably see Wang Lei's serious appearance and the final answer was as if it were Liu Hong.

Suddenly, Liu Hong's eyes lit up and said, "This is a powerful and powerful character. Your Excellency is the governor of Wangzhou."

Wang Lei smiled and said, "It's just below."

Zheng Xuan bowed and said, "Zhanye Village Man Zheng Xuan pays homage to the Lord"

A hint of respect in his tone

Wang Lei said: "You are welcome to Gong Kangcheng. It's great that you can come to Jizhou. No need to pay tribute."

Wang Lei’s solution just now made Zheng Xuan very curious

Zheng Xuan went straight to the topic and said excitedly: "Can Lord Wang explain what happened and how to calculate it? Just a few simple words list a bunch of strange symbols and calculate it."

In history, China has had a multiplication table of "Nine Nine Songs" very early

However, the multiplication table of "Nine Nine Songs" is oral inheritance without records. How to write it, just like many Chinese skills, it is oral passed down from beginning to end. There is no clear classic record. Nine Nine Songs do not add, subtract, multiply, divide and other punctuation marks, even reading articles do not have punctuation. More emphasis is placed on reading a hundred times. It is self-evident that people who read it read more books and gradually understand its meaning.

Zheng Xuan, Liu Hong, Xun Chen and others didn't understand what was going on after reading it.

After Wang Lei scratched his head and organized the words, he briefly talked about the plus sign, multiplication sign, division sign and equation. After Wang Lei explained it carefully so that Zheng Xuan and Liu Hong could not understand it.

Even so, Zheng Xuan and Liu Hong are still confused

Wang Lei explained the doubts in the eyes of the two people for several consecutive times before they could ease a little, but he did not really understand that Zheng Xuan was a person who likes to explore and said: "I heard Wang Zhoumu's words just now, punctuation marks, addition, subtraction, multiplication, and method. There is a complete system. Please ask Lord Wang to write a book and publish it before publishing it. In this way, all scholars in the world will benefit."

Wang Lei's mind flashed with a flash of inspiration: "Kang Chenggong is for scholars all over the world. I am indeed willing to write books. But if I were responsible for the time I spent every day, I rarely do much. I don't have to wait for me to come up with a complete system. I think it would take several years. I would rather leave it to Gong Kang Chenggong and Gong Yuan Zhuo to edit it together. Isn't that better?"

Zheng Xuan hurriedly said: "You can't do this kind of thing, how can I take away your reputation? Once I compiled it, everyone thinks this is what I think of, but this is Wangzhou Mu's wonderful idea. I can't take away Wangzhou Mu's reputation."

Liu Hong said: "I also agree that Wang Zhoumu is responsible for this matter himself."

Wang Lei shook his head and said, "Kang Chenggong, I'm busy dealing with government affairs in Jizhou. I really don't have enough time. You are studying and learning. This matter is just right. You don't refuse. The whole set of symbols of the mathematical system and some symbols I wrote in my writing just now have a standard. These are very energy-consuming. It requires great scholars like Kang Chenggong to protect them. With Kang Chenggong and Yuan Zhuogong, I can't feel at ease."

"Isn't that a...?"

Zheng Xuan thought of taking away Wang Lei's reputation and was reluctant to do so. An old man in his sixties once he took action, everyone would think that he did it.

Wang Lei nodded and said, "Master Zheng does not seek fame and fortune but does not like power at this time, but is petty. This is beneficial to reading and practicing calligraphy and helping future generations to increase their knowledge. Why do you refuse?"

"Mr. Wang is open-minded and Zheng Xuan admires it"

Zheng Xuan respectfully politely eyes excited

Immediately Zheng Xuan looked at Liu Hong and said, "Yuan Zhuo, you and I are in my early sixties, and I don't have much time to delay. It's better to resign and compile books with me to lay a foundation for future generations."

Liu Hong frowned and he was the prefect of Shanyang County and was about to resign...

Zheng Xuan also had a stern face when hesitated

Zheng Xuan shook his sleeves and said coldly: "Well, since Yuan Zhuo is unwilling to give up his power, I will not force me to edit it myself without you. I can't complete it if I don't believe it."

Liu Hong smiled bitterly and said, "What did Brother Kang Cheng say? Don't help you? I'm not here to retire. I'll go back to Yanzhou and resign the position of Shanyang County Prefecture before helping you compile books."

Zheng Xuan said directly: "Isn't it really a problem to solve the problem with a letter?"

Liu Hong shook his head and said, "What should be done when people have to do, and they can't leave it. They can't be done perfunctorily."

Zheng Xuan nodded helplessly and said, "It's better to be with you."

Wang Lei was happy in his heart that Zheng Xuan and Liu Hong would definitely stay in Ye County. In this way, Ye County has a great scholar who can become a scholar. Wang Lei said calmly, "Don't hurry up and take a slow start to do this when you first come to Ye County. If you have any need, just open your mouth or go to the provincial and ministerial palace to find me."

Zheng Xuan said: "Wangzhou Mu has to ask Wangzhou Mu for advice on the symbols. Especially the algorithm to answer the lighthouse problem just now is very interesting and needs guidance from Lord Wang."

Wang Lei said: "I will tell Kang Chenggong about these things as soon as possible to edit them."

With a good start, Wang Lei directly gained recognition from Liu Hong and Zheng Xuan. The two talked with Wang Lei very happily. This scene made Xun Chen look at Wang Lei in a daze. The look in his eyes made Wang Lei feel that Wang Lei is a mystery. What kind of talent does this young lord have not revealed.
