Zhao Han was fine and became very interested in planting sweet potatoes. So, under Zhao Han's personal involvement, a small nursery was set up in the yard, and ten sweet potatoes were planted, and the seedlings were raised in the yard.

Mao Geng received a letter from Fei Ge sent from Lin'an a few days ago. Mao Geng received a good news, that is, after Chen Liang read the letter he left, he mobilized Jing Wenyuan and finally decided to cross the sea to Chameng. At this time, he should have been on the sea ship voyage to Chameng.

The Feige Book Transmission System was finally opened twenty days ago. From Lin'an to Xinhua, from Lin'an to Penghu, after these two Feige Book Transmission Lines were opened, Mao Geng felt much better. Although the gap between the information age was still very large, there was finally a fast communication method. The major events that happened in Lin'an and Xinhua will not be transmitted to Mao Geng in more than three days. Feige Communication is still somewhat flawed. The information sent from Xinhua must be transferred through Lin'an. The carrier pigeons flying to Penghu in Lin'an still habitually have to take a rest in Quanzhou. I believe that soon after, the direct train from Xinhua to Penghu will be opened, the information transmission will not exceed two days.

Mao Geng was called by Zhao Yan again this day. Zhao Yan would go to the nursery where sweet potato seeds were raised in a few days, hoping that the sweet potatoes would suddenly sprout. But what was disappointing was that the nursery still had no movement so far. Regarding the fact that the sweet potatoes had not sprouted, Mao Geng always comforted Zhao Yan: Those who would sprout and germinate. However, Zhao Yan asked more questions, and Mao Geng himself was a little lacking in confidence. He was worried that if they really didn't sprout, he would have to ask the indigenous people to guide the planting of sweet potatoes, and his misfortune would be great. However, Mao Geng believed in science and believed that sweet potatoes would always sprout, which was just a little earlier or later. But Zhao Yan was obviously a little obsessed with it. In order to avoid Zhao Yan's constant questioning every day, Mao Geng had to think of other ways to divert the attention of the emperor.

On this day, Mao Geng invited Zhao Han to his laboratory. These were several inconspicuous bungalows. In addition to doing some experiments here, Mao Geng also trained his disciples here. But today, Zhao Geng only felt that Mao Geng's behavior was particularly mysterious, and he didn't know whether Mao Geng invited him to come because he wanted to see something new.

Mao Geng just said that he would ask Zhao Han to see a magical demonstration. In fact, this is not a magical thing, but this matter is still amazing in the Song Dynasty.

Zhao Yan saw two large porcelain bowls on the table. Mao Geng poured water into one of the porcelain bowls, then added brown sugar into the porcelain bowl, stirring it constantly to dissolve. After it was fully dissolved, the whole bowl of sugar water turned crimson. Mao Geng said at this time:

"Duke, this bowl of sugar water is now crimson. I will use a way to restore the transparency of this bowl of sugar water."

Zhao Shu said:

"Is there such a thing?"

However, Mao Geng brought too many magical things, and Zhao Yan had already believed it in his heart.

Mao Geng took advantage of the situation and said:

"Duke, today I specially invited the Duke to see this secret. It's better not to reveal it. This was originally a way to make money prepared for Taiwan. It was not only for the ability of the subordinates to not lose the bet, but also for the Duke to reach a great rule in Taiwan. It also asked the Duke to agree to the Duke's official, so that the subordinates dared to show it to the Duke."

When Zhao Han heard the first half of the sentence, he was still a little worried. After all, this was a bet with the emperor's grandfather. Even if Mao Geng won, everyone would be happy. However, as the emperor's grandfather, he seemed to be helping the emperor's grandfather. However, after listening to the second half of the sentence, he suddenly realized that if he wanted to establish a great contribution in Taiwan, he should support Mao Geng as expected, and said with a smile:

"Mr. Mao doesn't have to worry, I'll keep the secret for you."

After hearing this, Mao Geng was convinced and poured the activated charcoal that had been prepared into the crimson sugar water. In Zhao Han's opinion, the bowl of sugar water was originally crimson. Mao Geng claimed to restore the sugar water to its transparency, but now he added black things to the sugar water. Isn't this not only not transparent, but it will turn black? Doesn't Mao Geng understand such a simple truth? But it's obvious that Mao Geng has no intention of being entertained at all. Not to mention that Mao Geng does not have this courage, Mao Geng has always acted meticulously. Today's matter is a magic trick!

But as Mao Geng kept stirring the sugar water, a miracle happened. The original crimson red of the sugar water slowly faded away. After a while, the sugar fruit really began to become transparent. Until the sugar water became completely transparent, Zhao Yan was still a little unbelievable. No matter how you look at it, he felt that Mao Geng was playing a trick.

Mao Geng then poured the transparent sugar water from the bowl into another bowl, and only the black stuff was left in the original sugar water bowl.

Zhao Feng's eyes were still on, hoping to see some mystery in Mao Geng's tricks, but Mao Geng smiled and said:

"Duke, the next step is simple. Please see, this bowl of transparent sugar water will turn into white sugar in the next step."

Mao Geng poured the transparent sugar water into an iron pot prepared in advance, and then set a low heat below. Soon after, Zhao Han saw white salt-like things slowly precipitated, and simmered them slowly on the low heat until the water was completely dried, leaving only a layer of thick and transparent liquid at the bottom of the pot. As the fire went out, the thick slurry liquid turned into crystal solids. Mao Geng managed to pound it, and the pot suddenly turned into crystal-like things like salt.

Mao Geng used his fingers to stick some white crumbs into the pot, tasted them, and said:

"Please try it too, Duke, this is what the Xiaguan calls white sugar."

Zhao Han also stretched out his finger, stuck two pieces, put them in his mouth, and after tasting them, nodded and said:

"Not bad, it's sweet."

At this time, Zhao Yan no longer thought that Mao Geng was playing tricks in this matter, but Zhao Yan raised a new question:

"It is so hard to turn brown sugar into white sugar. Although white sugar is good, it is hard to say what the price can be sold at."

Mao Geng was very pleased that Zhao Han had such an economic mind. Now he was calculating costs, estimating prices, and demonstrating the feasibility of making money, haha!

Mao Geng smiled and explained:

"Duke doesn't have to worry. This is just a demonstration for the Duke. If you really want to produce white sugar, you don't need to be so complicated. White sugar is better than brown sugar. As long as the sugar is sold higher than brown sugar, everything will be easier. The Duke's move is actually to find a way to achieve rapid and prosperous future for Taiwan."

Mao Geng thought to himself, I was not going to demonstrate this to you, Zhao Han. According to Mao Geng’s original idea, he just wanted Zhao Han to see the finished product of white sugar, and was not going to let him see any process. But thinking about Zhao Han’s interests are the same as his own now, so he should not leak the secrets randomly, so he demonstrated the principle of turning brown sugar into white sugar in the original form. But after all, the actual process is very different from this.

Zhao Han's interest increased greatly at this point, and he immediately focused on this topic:

"It goes without saying that white sugar is naturally better than brown sugar. Of course, the higher price is not a problem, but what is this related to Taiwan?"

Seeing that Zhao Han was like this, Mao Geng threw out his trump card at the right time:

"Sugarcane is suitable for planting in Taiwan. As long as the Duke of the State strongly supervises the planting of sugarcane, within two or three years, the most and best white sugar in the Song Dynasty can be produced here."

Mao Geng has mentioned many times before that sugarcane should be planted vigorously, but most people think that rice is preferred. However, today Zhao Han has seen Mao Geng's technique of making sugar and has a little understanding of Geng's idea.
