Hangzhou in August, is indeed beautiful, under the broken bridge, receiving lotus leaves, students on a cruise, the sound of drums accompanied by a light laugh, from time to time in the small Yingzhou reverberation, everything is still the same as before, but only Jiang Ning, who has just stepped into the city of Hangzhou, knows that all this prosperity will indeed make people lose their fighting spirit.

This is still the case in the Qinling Mountains, not to mention the border, and the Tiger Ben army stationed in southern Zhejiang......

It has been about fifteen days since he left Hangzhou, and he was not in a hurry on the way back, everything was confirmed in the mouths of the Qingshan Gang, and he still didn't know where things had developed.

Re-entering the city of Hangzhou, the streets are still lively, although there is still half a month before the Mid-Autumn Festival, but the city of Hangzhou has begun to have the atmosphere of the Mid-Autumn Festival, and some stores have hung red lanterns.

Wang Ruoyan has been busy for half a month, and now the pressure is still very great, this pressure not only comes from the business, but also from the family, and there are more than ten days before the Mid-Autumn Festival, the Mid-Autumn Festival, the elders of the clan and the shopkeepers from all over the country will come back, and then the clan meeting will decide some big things, but Jiang Ning has not come back yet, which really makes her a little worried.

......The sound of horses' hooves from the entrance of the alley gradually became clear, Wang Ruoyan leaned over and looked out, presumably it was about to be empty again, and was about to sit back on the chair in front of the window, but saw Jiang Ning turn the pavilion at the door and appear in his eyes, a smile curled up at the corner of his mouth, he was relieved, and hurriedly walked towards the door.

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

I wanted to say a lot of words in my heart, but now I can't say a word, I want to ask what happened over there, if there is any danger or something like that, but I just said a word back, and I was inexplicable in my heart, and I couldn't help but want to laugh.

Jiang Ning was also stunned for a moment, why did he come up with such an abrupt sentence, but immediately smiled: "I'm back, I brought some specialties for you to try, right apricots and crescent moons?" ”

Wang Ruoyan and Jiang Ning walked side by side, the two just said some short words about their parents, and did not talk about anything in business, Wang Ruoyan knew that Jiang Ning actually didn't like the fight in the business field.

"If it weren't for our uncle, why wouldn't he be here?"

"Who's to say it's not......"

"Uh...... Ou shopkeeper ......" The two shopkeepers who had just spoken went out, but they bumped into Ou Lingyun head-on, but they were extremely embarrassed, bowed their heads and greeted Ou Lingyun, wanting to leave quickly.

"Later...... Don't say that outside, after all, it's the owner, and we, as the shopkeepers, don't chew our tongues. Ou Lingyun stood opposite the two of them and said a little sternly.

The two of them answered, left in a hurry, Ou Lingyun turned around and walked towards the door, he should have said this, but he just said not to say it outside, as for what to think, why do you say this, it is the freedom of others, and the attitude he showed is not to say it, but he does not deny that he is right, under this attitude, Ou Lingyun, as the most important shopkeeper under Wang Gongyong, his attitude represents the meaning of everyone to a large extent.

After Jiang Ning came back from outside, he was still living a free life, which made Ou Lingyun very angry, he thought that 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, and in five days, it will be the Mid-Autumn Festival, and this day has finally arrived, and he wants to let the Wang family know what a big mistake it is to choose Jiang Ning instead of him, and this mistake is enough to destroy the entire Wang family.

"Shopkeeper Ou is here, please come inside." Jiang Ning walked over head-on, and when he saw Ou Lingyun holding the account book in his hand, he must have something to find Wang Ruoyan, so he didn't want to bother, so he walked out as he spoke.

"Uncle, this is ......" Ou Lingyun saw Jiang Ning's posture of not caring about himself, and he was also a little unhappy in his heart.

Jiang Ning smiled: "Oh, it's okay, I saw a book with Mr. Xia yesterday, and I liked it very much, but it's a pity that the second half of the book is in the antique shop, and I took it back today to study and study." ”

"Oh, then my uncle is leaving." Ou Lingyun also smiled slightly, thanked Jiang Ning, and walked straight towards the hall.

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

The day before, I was playing chess with Xia Lao, and I accidentally saw this book, which was used by Xia Lao to pad the table, and was almost burned by him, and he asked for it, which was left by the Persians when they passed through Hangzhou, and somehow arrived at Xia Lao, the strange symbols on it looked like children's graffiti, so they didn't pay attention to it, but only Jiang Ning knew that this was not a handy graffiti, but Arabic numerals, and it was not a Persian who left the book, but an Arab.

At this time, the Arabs had already formed a preliminary system through the study of numbers, according to time, "Algebra", "Arithmetic" and other mathematical works have appeared, the geometric information such as one-dimensional quadratic equations and circles has also been relatively mature, and the application of negative numbers far exceeds the mathematical achievements of China.

Jiang Ning still knows about these, but he knows little about the application of knowledge in them, and it is a miracle to be able to find such a book in this era, and this one is a book that really contains chemical reactions and algebraic geometry, and the text on it should be able to be translated after a while according to the numbers and Jiang Ning's knowledge, which is why Jiang Ning has to find the second half anyway.

After searching for a long time, I finally found the lower half of this book with thick dust under the corner of the table of the antique shop that Xia Lao said, and it was still early, so I arrived at the hall on the second floor of Liu Ji, and sat by the window to take a look at the beautiful scenery of the West Lake.

Suddenly, a person appeared at the door of Liu Ji, Jiang Ning didn't care at first, but when he saw the person walking towards him, he recognized this person - Yang Siyuan, the second brother of the Yang family, according to the generation, Jiang Ning is a lifetime better than him, and he should call his uncle, but because the Yang family and the Wang family are rivals, this title is directly ignored.

Yang Siyuan's face was extremely ugly, especially when the sun hung in the northwest and the afterglow was a little red, his face was a little burnt.

Yang Siyuan didn't know that Jiang Ning was also here, but when he passed by, he saw Jiang Ning sitting by the window alone, he wanted to know why, he didn't have to ask Jiang Ning, but the time was no longer allowed, there were still five days, and they still had a way to solve it.

And the moment he saw Jiang Ning, what Jiang Ning had done before gradually came to his mind, was it this guy's hands and feet or other reasons?

He desperately wanted to know that Jiang Ning might be the last step in solving the mystery, and he was willing to give it a try, if not, it would be better, but what if?

Yang Siyuan knew the seriousness of the problem in his heart, and he couldn't care so much at the moment, and wanted to ask straight to the point, but he hesitated a little, and walked towards Jiangning, with an extra piece of silk in his hand, the color of this silk was golden, and it was the same as the Huang Jin who was taken out to participate in the selection that day, but it was divided into two pieces, and the fracture 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.

Because something is wrong with their Huang Jin......
