After Cheng Lingyun heard Qin Yu's words, the little stars in her eyes were very moved and threw herself into Qin Yu's arms, and whispered, "Husband, it's so good." Qin Yu smiled proudly, then hugged Cheng Lingyun in his arms, and said secretly, "Modern times don't have much effect on saying this, but ancient times are different, tsk." ”。

Is glass really valuable? Definitely not, but Qin Yu is ready to sell the glass at a high price, saying that it is not impossible to say that it is too valuable, of course, Qin Yu said this to express his feelings for Cheng Lingyun, and if he is numb, he doesn't need money, and if he says it from time to time, it can also promote the relationship between husband and wife.

The windows of Qingfengju were replaced one by one, and the glass was installed one by one, and after half a day, Qingfengju as a whole changed, no matter which room it was, the light was very sufficient, and you could see the outside when you sat in the room, whether it was a family member or a maid, they were all very excited, this glass was very precious at a glance, Qin Yu also installed glass on the place where they lived, it would be strange if they were not excited.

The glass is made, the mirror is not far away, the difficulty is actually not great, as long as the mirror is made, Qin Yu can start to implement the plan, first buy food from the major families, if they don't agree, then the glass mirror Qin Yu will set a higher price, they either spend money to buy it, or exchange it for food, no matter which one, for Qin Yu, it is acceptable.

Qin Yu took the time to tell the Kunlun slaves about the production method of the mirror in the afternoon, and asked them to study it first, and if they succeeded, they began to make mirrors, of course, the glass had to continue to be made, Qin Yu promised Li Shimin to change the glass for the palace, Qin Qiongcheng bit Jinna, and Qin Yu would not fall.

The heating and stove are enough for the palace to install, Qin Yu called the people of Qingfengju the next day, took the heating and stove to the palace, installed the heating and stove in the palace, and installed the Lizheng Hall first, after the installation was completed, Li Shimin asked someone to test it. The effect is very good, this time Li Shimin was very happy, and hurriedly ordered the family members of Qingfeng Ju to speed up.

The palace is very large, Qin Yu prepared a lot of heating stoves, but this time it took three days, the heating stoves of the palace were installed, and the shops selling heating stoves in Chang'an were also officially opened. There are more than thirty or forty sets. Of course. Tens of thousands of sets are not nothing, there are quite a few.

The business can be so good, and it has a lot to do with the heating coming from Qin Yu's hands, and it has a lot to do with the installation of heating in Qinfu's Cheng Mansion and the palace. This is the advertising effect, Li Shimin is the emperor, Li Shimin has installed heating, and others will follow suit whether they believe it or not.

There are too many orders, there are a lot of Chang'an scholars, rich businessmen, especially those big commercial houses, they all want to buy in large quantities and then send them to other places to sell, this is a business opportunity. Merchants understand very well, therefore, many large commercial houses have placed tens of thousands of sets of orders.

After Fang Yizhi and the others heard the news, they hurriedly walked towards Qingfeng Residence, ready to discuss with Qin Yu. There are too many orders, and the orders have reached 120,000 sets in just half a day, and they are still increasing rapidly, which is a big deal, so they can't be careless.

Qin Yu was lying on the recliner leisurely basking in the sun, when the maid came to say, "Master, Cheng Dalang, Cheng Erlang, Cheng Sanlang and Fang Langjun and others are here." ”。

Qin Yu was slightly stunned, then got up from the recliner and said to Cheng Lingyun Xiaotao, who was lying on both sides, "Madam, I'll take a look." ”。

"Yes, husband." Cheng Lingyun and Xiao Tao opened their mouths together.

Qin Yu nodded and then walked towards the hall, before he entered the door, he saw Cheng Huaimo, Cheng Huailiang, Cheng Huaibi, and a few people staring at the window and the glass on the door, and then laughed, and said secretly, "Dumbfounded, hehe, this thing is simple to make, but unfortunately Datang will not appear." Then he coughed, "Ahem." ”。

As soon as Qin Yu's cough landed, Cheng Huaimo, Cheng Huailiang and the others hurriedly turned around, looked at Qin Yu with an excited face, and opened their mouths to ask, "Brother-in-law (Brother Qin) (brother-in-law), what is this?" ”。

Cheng Huaimo Fang Zhichai Lingwu and the others were stunned for a moment, then smiled, and then looked at Qin Yu tightly, waiting for Qin Yu to answer.

Qin Yu smiled slightly, and then said, "This is glass, just made, how about it?" Do you like them all? ”。

Cheng Huaimo's eyes lit up when he heard this, and he quickly nodded and said, "I like it, I like it so much, brother-in-law, I don't want much, bring me three thousand pieces of glass." ”。

Fang Yizhi said excitedly, "Brother Qin, I don't want much, two thousand yuan is enough." ”。

Chai Lingwu Du Wei Chi Baolin said in unison, "Three thousand pieces of glass." ”。

Qin Yu laughed when he heard this, but not because he was proud, but because this glass could be so valued by Cheng Huaimo Fang Zhizhi and others, which shows how attractive the glass is, you can imagine what it will be like to put the glass in the store to sell it at that time, this is still ordinary glass, and glass products such as mirrors and cups, it will be even more popular.

After Qin Yu finished laughing, he immediately said, "No problem, isn't it glass, give as much as you want, who told us to have a relationship." ”。

Cheng Huaimo's three brothers, Fang Zhizhi, Du Gou, Yu Chi Baolin, and Chai Lingwu all laughed, at this time Chai Lingwu remembered something, and hurriedly asked, "Brother Qin, I'm afraid this glass is very valuable, right?" ”。

As soon as Chai Lingwu's words landed, Cheng Huaimo Fang Zhizhi and the others were stunned for a moment, and then reacted, this glass has never appeared in Datang, if it is not valuable, it would be strange, just wanted to open his mouth to take back the glass he had just asked for, but Qin Yu smiled and said, "What is precious or not, are you still polite with me?" If you still mention this, no one will come in the future. ”。

Cheng Huaimo's room was slightly stunned, and then their hearts warmed, but they were moved by Qin Yu's affectionate and righteous words, even if Cheng Huaimo's three brothers were the same, Qin Yu and they are relatives, but in addition to this layer of kinship, Qin Yu also regarded them as friends, and the three of them were equally moved, and after a while, several people smiled together, "Okay, don't mention it." ”。

Qin Yu smiled slightly, and then asked, "Brothers came over together today, what is this for?" Don't say that you are unpredictable prophets, you know that I have just made glass. ”。

Fang Yi laughed, and then said, "It would be nice if we could predict the prophet, Brother Qin, this time we came to tell you about the heating shop." ”。

"Heating? What's wrong? Qin Yu was slightly stunned. Then he asked.

Cheng Huaimo nodded, and then said, "Brother-in-law, that's the case, as soon as the store opened, many people came to buy heating, which is nothing, but later several major commercial houses came, and each of them placed tens of thousands of orders, and now there are 120,000 sets." There were still a lot of people placing orders when we came. ”。

"After we know. Fear of malicious vandalism. That's why I came to my brother-in-law to discuss whether to push off the orders of those major trading houses, or increase the number of people to eat their orders. ”。

Qin Yu was stunned when he heard this, but Qin Yu didn't expect that there would be such a big order for heating. It is not impossible for Cheng Huaimo to say that someone maliciously destroys it, there are so many orders, and the speed of heating production is not fast, and there are only 100 sets of 100 sets every day.

In more than a month, you will have to light the heating, and you will be able to make 3,000 sets this time, at most 5,000 sets, this point, someone who is interested can calculate it after a little inquiry, after all, Qin Yu gave Qin Qiongcheng a heater. Later, he installed heating for the palace, and after so many days, with a little calculation, he could estimate the amount of heating produced.

Even increasing the number of people is not so easy to do. The output of iron ore is limited there, what is the use of just increasing manpower, even if it is done by then, the time will have already passed, and the buyer can naturally use time as a reason to refuse to pay, Qin Yu will not be able to use his identity to deal with those major trading houses at that time, otherwise it will be true.

After pondering for a moment, Qin Yu immediately looked at Cheng Huaimo and said, "In this case, I will increase the number of people, increase the production speed of the heating, and the orders will be received correctly, and they will eat as much as they want, as for the orders of those commercial houses, tell them to pay the full amount, otherwise they will not accept them." ”。

When Cheng Huaimo and the others saw what Qin Yu said solemnly, they immediately felt a lot less worried, nodded in unison, and said, "Okay." ”。

Qin Yu suddenly remembered something at this time, and then said, "By the way, those people behind the firm, you go and investigate." ”。

Chai Lingwu immediately reacted when he heard this, and then said, "Brother Qin suspects that it is the prince's party?" ”。

Qin Yu was slightly stunned, then nodded, and said in a deep voice, "It's not impossible, check it, if it is, then there is no need for these trading houses to exist." ”。

Cheng Huaimo's widow, Chi Baolin, nodded solemnly, and then left Qingfeng Ju with gloomy faces one by one.

The order is a big order, you can make a lot of money, each set of planing costs, each person can get more than ten or twenty runs, Qin Yu can get more than three hundred, because the iron ore does not need money, it can be said that this money is a lot, Qin Yu can earn four or five million, if there are orders behind, then make more money.

Qin Yu thought for a while, then found the security guards and instructed them to prepare gunpowder, the purpose is very simple, open the mine, and replace it with quantity if the power is insufficient, so that the constraints of iron ore do not exist, and the rest is to send a large number of additional manpower.

In order to prevent people with ulterior motives from mixing in, Qin Yu did not recruit workers, but went directly to the palace in a carriage.

As soon as the palace gate was opened, General Cen and a group of soldiers bowed down in unison and said, "See King Qin!" The voice is extremely loud, who called Qin Yu is red and purple now, how long has it been, he has directly become the king of Qin, one person is above ten thousand people, and he is extremely noble, so they can't be disrespected.

Qin Yu smiled slightly, and General Cen hurriedly shouted to the soldiers, "Open the palace gate quickly!" ”。

"Squeak." As soon as it came, the palace gate opened, and now Qin Yu's status is still used to enter the palace, Qin Yu smiled at General Cen slightly, and then passed the palace gate, the change of identity, the weight of the smile also became heavier, Qin Yu's smile made the general surnamed Cen excited.

Qin Yu has long been familiar with the palace, as long as Li Shimin's concubines don't go, there is no problem, Qin Yu came directly to the Taiji Palace, the little eunuch guarding the door knew Qin Yu, and when he saw Qin Yu coming, he hurriedly bowed down and said, "See King Qin." ”。

Qin Yu nodded, and then asked, "Go and spread the word, this king wants to see Your Majesty." ”。

When the little eunuch heard this, he hurriedly bowed down and said, "King Qin, wait a while, and the little one will go and pass it on to King Qin." After speaking, he walked towards the Taiji Palace.

Not long after, the little eunuch hurriedly ran out, bowed down and said, "King Qin, Your Majesty has called you in." ”。

Qin Yu nodded, and then entered the Taiji Hall, and at a glance saw Li Shimin, who was sitting on the chair and busy with the performance, he was slightly stunned, and then bowed down and said, "Weichen greets Your Majesty." ”。

"Yunfei, you came just in time, I just learned that the method of drying salt has succeeded, and the fold says that the salt production on the seaside is extremely high, enough for the people of the Tang Dynasty to eat, and it is more than enough, hahaha, now the Tang Dynasty does not see that there is no salt available, you are my great hero." Li Shimin took the brush and drew on the fold, then closed the fold, looked at Qin Yu excitedly, and spoke.

Qin Yu was slightly stunned, but Qin Yu forgot about it, and then bowed down and said, "This is the duty of Weichen, Your Majesty, the current season is not suitable for drying salt, if it is summer, this salt production will be higher." ”。

Li Shimin's eyes lit up when he heard this, and he laughed loudly, "Okay, good." At this time, Li Shimin remembered something, and hurriedly asked, "Yunfei, in a few days, you will marry Qian'er Ling'er, now come to me, is there something wrong?" ”。

"Your Majesty, there is indeed something, Weichen wants to use that group of Tuyuhun prisoners of war." Qin Yu bowed, and then spoke.

Li Shimin was stunned for a moment when he heard this, and then asked, "Tuyuhun prisoners of war?" What is the use of Yunfei? ”。

Qin Yu bowed, and then said, "Your Majesty, Weichen needs manpower for mining and coal mining, not only that, but Weichen also wants to build a road, that is, with cement, so that when it rains and snows, the road will not be so muddy, and the carriages and horses will walk on it smoothly and will not be bumpy." ”。

Li Shimin was slightly stunned, then his eyes lit up, and he hurriedly asked, "Cement road construction, will it really be like this?" ”。

Qin Yu nodded very seriously, Li Shimin immediately smiled when he saw this, and then said, "Very good, I'm right." ”。

Qin Yu didn't say what he wanted, he would build the road for free, Li Shimin naturally agreed, and what Qin Yu said was too attractive, Li Shimin also wanted to see if such a road was so magical, as for Qin Yu taking prisoners of war for personal use, Li Shimin didn't take it to heart, Qin Yu would have rebelled a long time ago if he wanted to rebel, so why worry about it, not to mention that Qin Yu also said it bluntly, which Li Shimin was very satisfied with.
