"Duke Cheng is really in love with the world. For the sake of everyone's interests, he is willing to give up such a huge profit. He is really a role model for us!" When he heard that the golden trade route of grassland slave vendors was actually released, Li Jingheng was the first to jump out. He was not as good as his father. The only thing like his father was greedy for money. In addition, Li Daozong did not want his son to enter the official career again, so he let Li Jingheng get in trouble. Although this guy is from a noble background, his thoughts have completely transformed into a businessman.

Others have long been jealous of the profits brought by the slaves. Now when they hear that they have the opportunity to participate, they are all surprised and the words of praise and flattery are like a trend. Anyway, they are all juniors, and it is not embarrassing to flatter those old guys Cheng Yaojin.

"Haha, the release of grassland trade routes is only one of them. In addition, the slaves in Silla must also be released. This has been approved by Yan Changshi." Wang Zihao then dropped a bombshell and saw the old housekeeper of the Yan Mansion sitting at the last place at the same time.

"I'm here to see you all the young masters!" The old housekeeper stood up with a demeanor and walked a series of things to everyone sitting there. Then he said, "My young master just heard from Dengzhou that the business route of slave trade in Dengzhou must be relaxed. However, if you want to go to Silla to capture slaves, you must join the Dengzhou slave hunting association, and then the audience will command it in a unified manner."

Most of the people who live are smart people. From the fact that the grassland slave trade route was released just now, many people have guessed that Dengzhou might also open up the trade route, but when they really heard this happy event, they still couldn't help but be happy. Compared with the grassland, Dengzhou slave trade is less safe and cost. After all, Silla Baekje is a small country, and the folk customs are not as strong as the grassland. Even if people are sent to grab it, there will be no big losses. But it is different on the grassland. Nowadays, grassland slave traders usually organize caravans to buy slaves from various tribes, and the cost will definitely be higher. Moreover, transporting slaves from the grassland is by land, not as convenient and fast as Dengzhou waterways.

"Brother Huailiang, I finally know why Mr. Cheng promised to let go of the trade route of slaves on the grassland!" Just as everyone was cheering, Li Ke suddenly came to Cheng Huailiang's ear and said in a low voice.

After hearing this, Cheng Huailiang, Li Jingye, Qin Huaiyu and Li Ke looked at each other and laughed. Everything was gone. The families of several of them were preparing their own fleets and were about to go to Dengzhou to participate in the slave capture.

However, after the four of them laughed, the youngest Li Jingye suddenly had a flash of inspiration. He thought of another deeper intention, and looked around and didn't pay attention to him. He lowered his voice and said, "Everyone, with Liulang's temper, how could he let go of such two important trade routes for no reason? There must be some meaning here, and I heard that something happened in Goguryeo. Liulang now asked us to organize the fleet, would it be..."

When Li Jingye said this, he looked at Li Ke and the other two with meaning. After hearing Li Jingye's words, they all showed a deep expression of thought. After a while, they figured out what Li Jingye said, but they were immediately shocked. After a while, Qin Huaiyu said: "If it is really as Jingye guessed, then Liulang is a big deal this time. At that time, not only can he solve the problem of employing people in the mine in one fell swoop. We don't even have to worry about lack of people in the future."

"Everyone, please calm down. We have two things to talk about. Let's talk about the glass next." Wang Zihao waited for a while, and saw that everyone was excited because of the opening of the slave trade route, so he could only stand up and stop him. However, even if he came forward, it took a while to suppress everyone's excitement.

"Zihao, the sales situation of the glass factory is very good now. Is there any problem?" When someone heard about glass, he immediately asked loudly. Because of the canning, Li Yan had to take out the glass process and let everyone participate in the establishment of a glass factory. Now there are three huge glass factories in Chang'an alone, and there are many prefectures and counties around Chang'an, all of whom are working hard to produce glass bottles for canning. After all, in this era when food preservation methods were backward, canning is really popular.

"Everyone, that's right. The glass bottles produced by glass factories are indeed in short supply, but many people must have noticed that glass bottles can be used repeatedly. Now many canning factories are recycling used glass bottles. Although some glass bottles will be damaged, the market will sooner or later be saturated. By then, many glass factories now open will go bankrupt because they cannot receive orders."

When Wang Zihao spoke, his face was very heavy, but he was happy in his heart. At the same time, he was sighing at Li Yan's cleverness. When he first made the glass process public, Li Yan gave him an order to let more people open glass factories as much as possible, without caring about the excessive production of glass in the future. As a result, not only are there glass factories in Chang'an and surrounding areas, but even people in the southern provinces bought patents in Chang'an and went back to set up factories. So many glass factories are now producing only canned bottles.

"Zihao, although many people know this problem, the profits of glass factories are amazing now, so we have attracted a lot of people to open factories blindly. We have nothing to be afraid of. Anyway, the factories are large in scale and each company has their own canning factories. Even if they go bankrupt in the future, those small factories will go bankrupt first." A cold guy stood up and said, but his words were approved by many people.

"Everyone, the reason is true, but His Highness Qi thought of the new uses of two glass. If these two uses can be promoted, there is no need to worry about the sales of the glass factory in the future." Wang Zihao smiled mysteriously. Li Yan first used huge profits to trick many people into the ship, and then used greater profits to lead others to follow him.

"Oh, it was created by Liulang again. Let's talk to us about what it is?" When everyone heard that it was created by Li Yan, everyone became interested. Now Li Yan has become a profitable brand. As long as it is created by him, almost nothing is not profitable.

Wang Zihao waved his hand outside at this time, and immediately several servants came over with a box made of wood, and then placed it beside him. Everyone looked carefully and found that it was an ordinary field-shaped shelf, but in the four boxes of the field, there were glass inlaid. For a moment, they couldn't tell what they were for?

Wang Zihao smiled and pointed to the wooden frame and said, "You may be a little unfamiliar with this thing, but if you inlaid it on the wall, you will definitely know it!"

"Inlaid on the wall. Isn't that a window?" Li Jingye reacted the fastest and immediately shouted loudly. After he reminded him, the others also woke up one after another. Looking at the wooden frame, although the workmanship is extremely simple, it does look like a window. It just used glass instead of the window paper we use now.

"Yes, this is the new purpose of glass. The current window paper is opaque. Even during the day, if the window is not opened, the room will be dim. But if the window is opened, it will be fine in spring and summer. In autumn and winter, the cold wind alone will be unbearable. If glass is used instead of window paper, there will be no problems as above. It is not only bright, but also can prevent dust. Whether or not the window is opened will not have any impact." Wang Zihao introduced excitedly.

Everyone can understand the benefits of using glass as windows. But no one has ever thought about this problem before. After all, in their minds, glass is still a expensive luxury. Even if there are cheap glass bottles everywhere now, this concept cannot be reversed in one or two days.

"I found that we seemed to fall into Liulang's trap. Why do we feel that this glass is so similar to the charcoal from the beginning?" Qin Huaiyu suddenly said with a wry smile. The same was true for charcoal at the beginning. It was only used in cement factories, but later Li Yan invented honeycomb coal, which began to be promoted among the people. Now the promotion process of this glass is simply a copy of charcoal.

"Yes, this is already Liulang's old method, but it has been tried and done many times. Even though he knew it was a pit, I believe many people were willing to jump down." Li Ke also said with a wry smile. Although there were many smart people present, they did not mind being plotted by Li Yan at all. Like others, they all applauded the creativity of this window.

"Haha, compared to this window, His Highness King Qi has bigger hands." After everyone calmed down, Wang Zihao said again, "This thing is called a glass greenhouse. I don't know what it is, but according to Your Highness's letter, it is used to grow vegetables in winter. I believe everyone must have a deep understanding of the preciousness of fresh winter vegetables!"

In fact, in the Tang Dynasty, vegetable planting technology was already available in winter, but it had to rely on hot spring water to irrigate. Therefore, the limitations were greatly limited and the yield was not high. They had to pay tribute to the palace every year. Occasionally, Li Shimin would reward some ministers, so it seemed particularly precious.

"Is there such a thing?" Everyone was stunned after hearing this and whispered to each other. Although Li Yan's reputation was guaranteed, it was a bit incredible that this glass greenhouse could grow vegetables in winter, so they all became a little doubtful.

"Zihao, can you tell me in detail? Although this glass greenhouse sounds good, it is difficult for us to make a judgment before we see the real thing." Cheng Huailiang shouted loudly, and the others nodded one after another. Now everything is speculation, so it is better to see it with your own eyes.

"Mr. Cheng, I'm really sorry. Because the craftsmen sent from Dengzhou are still on the road, I don't know very well. But at most half a month, the craftsmen can reach Chang'an, and we will know it at that time." Wang Zihao said helplessly. The journey from Dengzhou to Chang'an was too far. He had received the letter for a long time, but the craftsmen still hadn't arrived.

"Since that's the case, then let's put this matter aside for a while and wait until someone comes." Li Ke waved his hand and made a decision, and the others nodded in agreement.

"Okay, let's talk about the textiles that we have prepared since last year. Although not much of this year's cotton can be obtained in our hands, according to Your Highness, this industry is the top priority in the future, and everyone knows it. Let me start now and tell me how your preparations are?" Speaking of textiles, Wang Zihao immediately became excited. The cotton was taken away by the Ministry of Industry last year. However, at the beginning of this year, the Ministry of Industry vigorously promoted cotton planting. They planted a lot of them. Although most of these cottons have to be handed over, some can be left, just for future technical accumulation.
