"Su Gong, Mr. Shao," Yao Huan explained, "In fact, the biggest thing that Hu bean baking and tea cake roasting have in common is that neither can be smoked through direct fire. But there is a difference, tea cakes only need to be warmed by human hands, while Hu beans need much more heat. Su Gong, I don't know if there is such a stove, after the wind is blown in, the hot air from the charcoal fire enters a closed iron cylinder, and the iron cylinder itself is rotating, and the beans are tumbling in the heat in it, and it will not be completely scorched because it sticks to the inner wall of the iron barrel, but it can bake out the fragrance. ”

Su Song listened, pondered for a while, turned to face the wooden shelf in the study, squinted his eyes for a while, and pulled out a small thread-bound book.

Turning over the folded paper, it turned out to be drawings with various mechanical details.

After all, Su Song is old, and the speed of flipping pictures is inevitably slow.

Shao Qing stared at those pictures, and when he swept a few line drawings that vaguely looked like a bed crossbow, his heartbeat immediately increased.

His guess was confirmed, and the Fang family, who had made great achievements in the installation of the instrument elephant platform, like Shen Kuo, really liked to study crossbows and weapons.

Yao Huan, on the other hand, was even more excited.

She secretly thought that if she remembered correctly, Su Song would live until after Zhao Ji ascended the throne.

This old gentleman has no perverted obsession with power, he walks to the poor place of water, sits and watches, retirement is retirement, reading books and roasting tea and doing handicrafts, how good. Because of Su Yu's introduction, she may really be able to use the power of this great scientist to make a device for roasting coffee beans.

Su Song's hand flipping through the book finally stopped on a certain page.

He pointed to an object on the picture and said: "When the old man was in the south, I saw that Jiangnan people loved to eat a kind of roasted chestnuts, which were baked with maltose to make them yellow and clear, oily and moist, and the chestnut fragrance was rich. The drum shape of the grill they used was cranked by hand, and the old man drew it roughly. Yao Niangzi, it's better to do this, you bring the beans another day, let's give it a try, if this bean is roasted with fire, what kind of heat must be used, the taste is good. And then we can design the mechanism according to the heat, how about it? ”

Sugar-fried chestnuts?

That's right, you can also learn from the method of stir-frying chestnuts in sugar.

The so-called tactile bypass is like this.

Yao Huan happily thanked him.

Su Song, who has passed the primeness of this year, has many sons, and the female doll born to the youngest son is as big as Yao Huan.

Su Song's family style is clear, and his children and grandchildren are not gentlemen, but the youngest granddaughter in the boudoir is delicate and weak, and Yao Huan came out to work hard to make money at this age, which is still incomparable.

As an elder, Su Song sees Yao Huan as a child worthy of pity and help.

And this former top figure in politics not only does not exclude business itself, but also supports it very much.

Su Song took a sip of tea and said in a harmonious voice: "The lady doesn't have to be polite, the old man is really willing to see that you are in the business, and the business is prosperous." The old man has seen from the officials over the years that in places such as Gyeonggi, Hedong Road, Jiangnan East Road, Liangzhejiang Road, and Shudi, where commerce and trade are prosperous, it is difficult for land to be concentrated in the hands of large "main households" (main households, that is, landlords). Mrs. Yao, you have been cooking with Aunt Ling for a while, but the old man wants to ask you, why is it that in Luzhou, where the city is thriving, no matter how good the fields are, the rich families don't seem to buy much? This is very different from the Tang Dynasty. ”

Yao Huan said bluntly: "Because people are expensive." ”

"Oh?"

Not only Su Song, but Shao Qing also had a puzzled look in his eyes.

Yao Huan said: "The world thinks that the sale of my fields is not as restricted as the previous dynasty, and the fertile land should be more concentrated." This is not the case. How can the main household spend money to hoard fertile land, how can it be abandoned? They must hire landless tenants to farm. But I have been gracious to all the people, and I have heard the people go out of the towns and counties to the cities, to be hired and to receive their rewards. For example, in our East Water Gate area, even if we hire a young helper in a small restaurant, we have to go out once or twice a month. If they are more diligent on their legs and feet, they can sometimes earn extra money as laborers and craftsmen in their spare time. This is much higher than the profit that many tenants can earn in a year by renting acres of land from their owners. ”

Shao Qing continued: "I understand, the so-called rising tide lifts all boats, and in the field, the bid of the main household to hire tenants is also higher. If they hoard a large amount of fertile land and have to pay much higher than the previous dynasty to hire tenants, the main tenants should think before they make a move. ”

Su Song smiled knowingly. Two young people, one with practical experience and the other with a sensitive mind, are really instructive.

"What you two are saying is the crux of the matter. The old man has worn official uniforms for decades, and the most admired for the virtuous ministers of the former dynasty is Liu Yan, the prime minister of the Tang Dynasty. According to the legend, Liu Xiang has the eye of heaven, and when he sits on the temple of Chang'an, he can see the flow of money and grain in the world. In fact, how can there be such a god, but it is better to read thousands of volumes of newspapers than to travel thousands of miles of prefectures and counties, to understand where the lifeblood of the country is, and to understand why the people support this law and reject it. ”

Su Song seemed to have said something that was in high spirits, and he didn't shy away from talking about the previous dynasty for a while, staring at Shao Qing and Yao Huan with burning eyes: "In the early years of Shaosheng, how many people said that I was a minister of the Yuanyou Party, but in fact, the old man hated the party struggle the most, and he hated the right and wrong caused by the party struggle even more. When Wang Xianggong implemented the law change, why did the old man oppose him without saying anything? On the contrary, the old man also studied the new law of the officials, and only hoped that he could extract the essence from the rough. Decrees are dead, people are alive, and things in the world are alive, Shao Lang, you used to live in the Jingzhao area, have you ever heard of the neighboring town of Hebei West Road, and salt is not a monopoly of the imperial court? ”

"Huh?"

Shao Qing's heart sank. The old man has mentioned the matter of the north for the second time today......

"Su Gong, the younger generation is ashamed, before coming to Kaifeng, he only studied the scriptures and the scriptures behind closed doors, and studied the pharmacology of medical prescriptions, and he didn't know much about Jingzhao's decree, let alone Hebei Road."

Su Song stared at him and continued: "Back then, Emperor Renzong was written on the map of Bao Long, please cancel the official salt monopoly on Hebei Road. Indeed, he was a minister of society. Think about the Hebei Road, adjacent to the Liao State, after the Song and Liao wars, the trade routes were unblocked, and the private salt of the Liao State was transported to the Han land, how easy. The official salt of the imperial court, or due to the entanglement of interests between officials and businessmen, the quality and price are high, and the people naturally go to buy Liao salt. If it is connived, the Liao people will profit a lot, and if they are killed, it may provoke the people of Han to revolt. Therefore, as Bao Longtu said, the monopoly of official salt should be abolished and the Han people should be allowed to sell private salt. ”

"Bao Long Tu? Is it Bao Gong who sprayed all his spit on the face of the official family when he was arguing with the first emperor? Yao Huan asked curiously.

Su Song pursed her lips: "Mrs. Yao knows a lot, it is this Bao Gong." ”

His eyes glanced at Shao Qing, and he saw that the young man also showed appreciation.

Su Song's heart moved.

He suddenly found that the pair of people in front of him was actually quite a good match, but he was too old to be nosy, he met Shao Qing some time ago, and learned that this future life was not married, and he also wanted to be a matchmaker for a clan girl of the old Zhao family.
