The next morning, Yang Wencheng arrived at the Ma family and formally taught Ma Mingfeng.

I have to say that Yang Wencong's talent is indeed not a big deal, and he has a good lecture. He starts with the Four Books, usually speaking for a long time, the Four Books and Five Classics, and the other half of the day explains the Eight-Legend Essay, starting from the format, and then analyzing various cases. Even how to conceive, how to write, etc. are explained in detail.

Yang Wencong is like a good teacher who is good at temptation. Ma Mingfeng is focused, listens carefully, remembers carefully, and makes progress very fast. Even Yang Wencong appreciates it.

Time flies very quickly, and a month has passed in a blink of an eye. During this month, Ma Mingfeng studied the Four Books, Five Classics and Eight-Legendary Essays with Yang Wencong during the day, and studied hard at night, trying every means to improve his level. He often went to rest in the early morning, and really turned a blind eye to the things outside the window and focused on reading the books of sages.

Of course, this does not mean that Ma Mingfeng does nothing except studying. First of all, Ruan Dacheng really brought the one thousand taels of silver and carriage package. He had never felt the impact of a thousand taels of silver before. The carriage was decorated very beautifully. There was a carriage, and when he got on the carriage, he could sit comfortably in it. He could not feel the wind and sun at all. Ruan Dacheng also sent two tall horses. These two horses were famous Western species, famous for their strong endurance and good at walking far away.

In addition, Ruan Dacheng also gave him a few clothes and two robes, and even his shoes and socks were all available.

All of this made Ma Mingfeng amazed. Ruan Dacheng was indeed a good person, and he actually bought it so well.

In addition to this matter, Ma Mingfeng is also thinking about making money.

In order to open up one's ideas, Ma Mingfeng even thought about the records of Guizhou in the past few years in later history, but he knew that Guizhou had not had large-scale floods and drought disasters in recent years, so it should not be too short of food. Moreover, Guizhou is steep, so it may not be so easy to transport grain in the past.

In this way, Ma Mingfeng didn't know what to do.

Ma Mingfeng really had no choice, so he decided to ask the maids and servants for ways to make money. On that day, Yang Wencong happened to have something to do. Ma Mingfeng was worried about making money, so he casually mentioned to Xiaosi Chunwang.

Chunwang said with a sudden idea: "I don't know much about making money, but Mr. Wu may know that it is said that Mr. Wu was originally a businessman in the north and ran a large industry, but later he was invaded by the Qing army, and all the industries of the Wu family were gone. At that time, the master was in office as the prefect of Datong. Mr. Wu wanted to die when he was in a downturn, but was rescued by the master. Mr. Wu was grateful for his kindness and was hired as the master."

"I know this Mr. Wu, Chunwang, like that, if you go and invite Mr. Wu, just say I have something to ask. Forget it, I'll go there in person. Chunwang, you can lead the way."

After Ma Mingfeng finished speaking, he went to the account room under Chunwang's leadership.

When Ma Mingfeng came outside the tent, he could only hear the crackling sound of plans inside. Ma Mingfeng knew that the other party was settled, so he quietly pushed the door and walked in.

Mr. Wu is a middle-aged man in his forties. He dresses very neatly and concisely, and his mental state is also very good. He has a red face. He knows Ma Mingfeng. When he saw Ma Mingfeng coming, he nodded to Ma Mingfeng and said hello, and then continued to make abacus and make calculations.

But seven or eight minutes passed, and Mr. Wu's calculations still did not stop, which surprised Ma Mingfeng. What is the problem? It is so difficult and has not been calculated for such a long time?

So Ma Mingfeng quietly walked forward and saw what the other party was calculating. He saw a piece of paper with 2.8×23.4+11.1×57.6+6.54×28. Of course, these formulas were actually written with symbols of calculations. Ma Mingfeng combined Ma Luan's original deity and his own memory to translate those symbols into mathematical formulas of later generations.

Ma Mingfeng felt that this should be something like calculating the land area, but no matter what, he could do this question, and it was very simple to do it, so he spoke: "This number is not difficult to calculate, the final result should be 888, which is quite auspicious."

"Hmm?" Mr. Wu looked at Ma Mingfeng in surprise, but he continued to calculate. It took about a quarter of an hour to finally calculate it, but it turned out to be 888.

Mr. Wu had a look of shock on his face and bowed to Ma Mingfeng and said, "Just just now, the eldest young master said the result was 888. Wansheng still didn't believe it. Now it seems to be true, but why did the eldest young master calculate so quickly?"

"Haha, this is actually very simple. You think of 28 times 6.54 as 2.8 times 65.4, so the first multiplication equation and the last one are actually 2.8 times 88.8. By the same token, the middle equation can be regarded as 11.1×8×7.2, that is, 88.8×7.2, plus 88.8×2.8, that is, 88.8×10..."

Mr. Wu looked thoughtful, and finally realized it at the end. He said to Ma Mingfeng with admiration: "The eldest young master is so clever. I really admire him!"

"Haha, Mr. Wu, why are you so polite? This is just a little trick. I learned it when I was a teenager." Ma Mingfeng did not lie. This is a basic Olympiad mathematics problem. It is a piece of cake for him who has experienced the layers of tests from junior high school to junior high school.

Mr. Wu stared at him with an incredible look on his face: "I don't know which famous master is? Such an algorithm is simply shocking and terrifying. If you have the chance to meet him at night, I really want to pay a good visit."

"This gentleman has been alive for many years, and you may not be able to see him sir."

"So that's the case, that's a pity. Fortunately, this gentleman has a successor. You have inherited his mantra. When you meet the eldest master at night, it seems like you met that gentleman. By the way, the eldest young master came to the account room. I wonder what you are doing?"

"This is the thing," Ma Mingfeng said slowly: "I'm not hiding it. Xiaosheng heard that the teacher had been doing business, so he came to ask for advice. Xiaosheng wanted to return to his original hometown Guiyang Mansion, but he happened to have some capital in his hand. He wanted to use this capital to take the opportunity to do some small business and make a small profit, but Xiaosheng didn't know what goods to resell? The teacher was knowledgeable, could he advise Xiaosheng?"
