Hangzhou in August is indeed beautiful. Under the broken bridge, lotus leaves are clinging to the sky, and students are boating among them. The sound of drum music is accompanied by chuckles, echoing on Xiaoyingzhou from time to time. Everything is still the same as before.

However, only Jiang Ning, who had just stepped into the city of Hangzhou, knew that all this prosperity would indeed make people lose their fighting spirit.

This is true for the Qinling Mountains, not to mention the border, and the Huben Army stationed in southern Zhejiang...

About fifteen days have passed since he left Hangzhou. He was not in a hurry on the way back. Everything was confirmed by the people in the Qingshan Gang. He still doesn't know where things have developed.

Entering the city of Hangzhou again, the streets are still very lively. Although the Mid-Autumn Festival is still less than half a month away, the atmosphere of the Mid-Autumn Festival has already begun to appear in Hangzhou city, and some stores have already hung red lanterns.

Wang Ruoyan has been busy for half a month, and now she is still under a lot of pressure. This pressure comes not only from the business world, but also from home. In more than ten days, it will be the Mid-Autumn Festival. During the Mid-Autumn Festival, the elders of the clan and shopkeepers from all over the country will come back.

, it will be a clan meeting to decide some big things, but Jiang Ning hasn't come back yet, which really makes her a little worried.

"Pap tap tap..." The sound of horse hooves coming from the alley gradually became clearer. Wang Ruoyan leaned out and looked out. He must have had another empty rejoicing. He was about to sit back on the chair in front of the window when he saw Jiang Ning.

Turning around the door, the pavilion appeared in sight. A smile curled up at the corner of his mouth. Feeling relieved, he hurriedly walked out the door.

Jiang Ning tied the horse, and when he turned around, Wang Ruoyan had appeared behind him. He looked at Jiang Ning with a smile and said, "My husband is back. It's good to be back..."

There were many words that I originally planned in my heart, but now I can't say a word. I wanted to ask what happened over there, whether there was any danger, etc., but I just said "come back". I was also confused in my heart.

I couldn't help but want to laugh.

Jiang Ning was also stunned for a moment, why did he say such an unexpected sentence, but he immediately smiled and said, "I'm back. I brought some specialties for you to try. By the way, where are Xing'er and Yue Ya?"

Wang Ruoyan and Jiang Ning walked side by side. The two only talked about family matters and did not talk about anything about business. Wang Ruoyan knew that Jiang Ning actually did not like fighting in the business field.

"If it weren't for our uncle, why would he be like this?"

"Who says it's not..."

"Um... Shopkeeper Ou..." The two shopkeepers who just spoke went out and bumped into Ou Lingyun. However, they were extremely embarrassed. They lowered their heads to greet Ou Lingyun and wanted to leave quickly.

"From now on... don't say that outside. After all, we are the boss. As shopkeepers, we should not talk nonsense." Ou Lingyun stood opposite the two of them and said sternly.

The two of them responded and left in a hurry. Ou Lingyun turned around and walked towards the door. He should have said this because of the situation, but he just said not to say it outside. As for what to think and why he said it, he didn't know.

It is the freedom of others, and his stated attitude is not to say it, but he does not deny that what he said is right. Under this attitude, Ou Lingyun, as the most important shopkeeper under Wang Gongyong, his attitude represents to a large extent

understand everyone's wishes.

After Jiang Ning came back from the outside world, he still lived a carefree life. This made Ou Lingyun very angry. He thought Jiang Ning should at least bear something. After all, he was the culprit of this matter, but Jiang Ning did not.

The shopkeepers have almost arrived. In five days, it will be the Mid-Autumn Festival. This day has finally arrived. He wants to let the Wang family know what a big mistake it is to choose Jiang Ning instead of him. This mistake is enough to make the entire Wang family

destroy.

"Shopkeeper Ou is here, please come inside." Jiang Ning walked towards him and saw Ou Lingyun, holding a ledger in his hand. He must have something to ask Wang Ruoyan, so he didn't want to disturb him, so he walked out.

"Uncle, this is..." Ou Lingyun felt a little displeased when she saw Jiang Ning's attitude of not caring about her own affairs.

Jiang Ning smiled: "Oh, it's okay. I saw a book with Mr. Xia yesterday and liked it very much. Unfortunately, the second half of the book is in an antique shop. I will pick it up today and study it."

"Oh, well done, uncle." Ou Lingyun also smiled slightly, thanked Jiang Ning, and walked straight towards the hall.

Jiang Ning looked at the Persian book in his hand, didn't feel anything was wrong, and went straight out the door.

I was playing chess with Mr. Xia the day before, and I accidentally came across this book. Mr. Xia used it to cover the table, and almost burned it. He asked for it. It was originally left by the Persians when they passed through Hangzhou. I don’t know.

Why did they end up here, Mr. Xia? The strange symbols on it seemed to them like children's scribblings, so they ignored them. But only Jiang Ning knew that these were not scribblings, but Arabic numerals, and the one who left the book was not

Not Persians, but Arabs.

At this time, the Arabs had already formed a preliminary system through the study of numbers. According to time, mathematical works such as "Algebra" and "Arithmetic" had appeared, and geometric information such as quadratic equations and circles were also relatively mature.

, the application of negative numbers far exceeds China’s mathematical achievements.

Jiang Ning still knew about these things, but he had only a limited understanding of the application of the knowledge. It was already a miracle that he could find such a book in this era, but this one actually included chemical reactions and algebraic geometry.

The text on the book should be able to be translated based on the numbers and the knowledge Jiang Ning has mastered. This is why Jiang Ning has to find the second half no matter what.

After searching for a long time, I finally found the second half of the book, which was covered with thick dust, under the corner of the table in the antique shop that Mr.

Look at the beautiful scenery of West Lake.

Suddenly, a person appeared at Liu Ji's door. Jiang Ning didn't pay attention at first, but when he saw the person walking towards him, he recognized the person - Yang Siyuan, the second son of the Yang brothers.

According to seniority, Jiang Ning was a generation older than him, so he should be called uncle, but since the Yang family and the Wang family were bitter enemies, this title was simply ignored.

Yang Siyuan's complexion was extremely ugly, especially when the sun was in the northwest and the afterglow was a bit dark red, making his face look a bit burnt.

Yang Siyuan didn't know that Jiang Ning was here. He just saw Jiang Ning sitting alone by the window when he was passing by. He wanted to know why. There was no need to ask Jiang Ning, but time did not allow it. There were still five days.

Time, they still haven't found a way to crack it.

The moment he saw Jiang Ning, what Jiang Ning had done before gradually emerged in his mind. Was it this guy's doing or was it due to other reasons?

He desperately wanted to know that Jiang Ning might be the last step in solving the mystery. He was willing to give it a try. If it wasn't, that would be better, but what if it was?

Yang Siyuan knew the seriousness of the problem in his heart, and he didn't care about so much at the moment. He wanted to ask straight to the point, but he hesitated a little and walked towards Jiangning. He also had a piece of silk in his hand. The color of this silk was golden.

, the same as the Huang Jin that was taken out for selection that day, but it was divided into two pieces, and the break in the middle was particularly eye-catching.

This is also the reason why Yang Siyuan has not been able to take a good rest in the past few days.
