It didn't take long for Gonggong Yang to come to Qin Yu in a hurry, that is called a passion, can you not be enthusiastic, just now Qin Yu gave thirty taels of silver, this thing is not so easy to get, if it weren't for the Yongnian Cui Wencui big fat man, Qin Yu didn't have it, catch up with the joy, and reward the remaining bit of silver to this Yang Gonggong.

"Little grandfather, you said earlier that you were going to come to the palace, and the miscellaneous family is waiting for you, how lonely you are to come by yourself." Yang Gonggong said kindly while leading the way.

When Qin Yu heard this, the corners of his mouth twitched unnaturally, and he said secretly, "I'll go, you're lonely, I'm not lonely, sitting with you, it's not goosebumps." After smiling slightly, he said, "Isn't it that I haven't eaten breakfast, and it's not too late to come back after breakfast." ”。

As for the change of the title of Yang Gonggong, Qin Yu knows very well, how many Tang Dynasty can be the founding county princes, Qin Yu can be regarded as officially becoming the Tang Dynasty, and he is the prince of the country in two steps, and it is nothing for Yang Gonggong to call the little grandfather.

"Little grandfather, look at what you said, when you come to the palace, Bixia can still take care of the food." Gonggong Yang said very kindly, as if Li Shimin was so close to Qin Yu.

Qin Yu smiled, coped with a few words, and not long after, he came to the Taiji Palace, Li Shimin was dealing with the twists and turns, after Yang Gonggong passed the word, Qin Yu immediately entered the door, and saw the busy Li Shimin at a glance, and said secretly, "Sure enough, it is worthy of Li Shimin in history, diligent enough." Then he stepped forward and bowed down and said, "The grass people meet Bixia." ”。

Li Shimin didn't raise his head, nodded, and continued to look at the twists and turns, Qin Yu was slightly stunned, but Li Shimin's state at the moment was a little wrong, and his brows were tightly locked, obviously. Li Shimin seems to have encountered some problems.

Half an hour later, Qin Yu's legs were numb, Li Shimin was still looking at the folds, and it was the one he saw before, Qin Yu turned his head to look at it, the corners of his mouth twitched, and he said secretly, "Why don't you even have a chair." ”。

At this time, Li Shimin sighed for a long time, and then twisted his eyebrows with his hand. Picked up the teacup and took a sip of tea, then looked at Qin Yu, "Yunfei, I only saw it yesterday, why did you come here again today." Is there something wrong? ”。

"Bixia, there's something really wrong. But it's a small thing compared to Bixia's matter. Bixia, you are busy first, and the grass people just wait. Qin Yu said with a smile on his face.

Li Shimin was slightly stunned, and then let out a long sigh, "Alas, this matter is indeed a big deal. But I couldn't think of a solution for a moment. As soon as Li Shimin finished speaking, he suddenly remembered something and hurriedly looked at Qin Yu. opened his mouth and said, "Yunfei, I ask you, if the soldiers of the Tang Frontier are short of salt, how to solve it?" ”。

Qin Yu was stunned when he heard this, and said secretly, "It's not such a coincidence, right?" At this time, Li Shimin continued, "Not only the frontier soldiers, but also the people of the Tang Dynasty are short of salt, and a lot of salt mines have been discovered, but the salt there is not edible, it is poisonous, if there is no salt, the body will be weak, the people can not cultivate the fields very well, and how can the soldiers who defend my Tang frontier resist foreign enemies." ”。

After Qin Yu heard this, he immediately bowed down and said, "Bixia, in fact, this matter is not that difficult. ”。

"Huh?" Li Shimin was slightly stunned when he heard this, and then stood up suddenly, stared at Qin Yu tightly, and asked very eagerly, "Quick, say, how to solve it." ”。

Qin Yu sighed secretly, then bowed down and said, "Bixia, in fact, this salt mine mostly has some impurities and heavy metals and the like, you only need to crush and dissolve it, filter it many times, and then cook it, of course, if you want to extract salt from seawater, you only need to dry the salt, so you can get more salt and faster." ”。

When Li Shimin heard this, he still didn't understand what Qin Yu meant, Qin Yu saw this, bowed, and then said, "Bixia, the grass people write down this method of making salt, you can send someone to follow the steps written by the grass people." ”。

This time, Li Shimin understood, his eyes suddenly lit up, and he shouted loudly, "Okay, Yunfei, come here quickly, just write here." ”。

Qin Yu nodded, and then came to the table, Li Shimin was slightly stunned when he saw that Qin Yu was not on his side, then smiled and said, "I will polish the ink for you." ”。

Qin Yu was slightly stunned, but after seeing Li Shimin's appearance, Qin Yu knew how anxious Li Shimin's heart was, so he didn't speak, and then picked up Li Shimin's writing brush, pondered for a while, and then dipped it in ink and wrote.

Two methods, one for the salt mine, the other for the sea salt, Qin Yu wrote each step in great detail, Li Shimin came to Qin Yu's side to take a look, and suddenly his eyes lit up, who called Qin Yu to write the head is the Tao, after Qin Yu wrote the method, he thought about it, and took the inkstone to draw a schematic diagram of the structure of the seaside salt field, and also wrote down the places to pay attention to.

When Zuihou finished writing, Qin Yu exhaled a long breath, and then bowed down and said, "Bixia, according to this method, you can make exquisite table salt." ”。

Li Shimin kept watching Qin Yu write, after Qin Yu finished speaking, Li Shimin exhaled a long breath, then picked up the words written by Qin Yu, read it, and after a while, he was suddenly stunned, even if the rest is forgotten, Li Shimin can also understand, but the cement needed for this salt farm stumped Li Shimin, "Yunfei, what is this cement?" ”。

Qin Yu smiled and explained, "Bixia, this cement is a good thing, it is made of calcination of a variety of materials, with it, the road can be made extremely smooth, the house can be built faster and stronger, and the construction of a salt farm by the sea will also become simpler." ”。

Li Shimin was slightly stunned, and he didn't understand what cement was after listening for a long time, but Qin Yu had been talking like this, although Li Shimin didn't understand, but Li Shimin knew a little, Qin Yu could make cement, I saw that Li Shimin was suddenly relieved, and then said, "Yunfei, can this cement be made in three days?" ”。

When Qin Yu heard this, the corners of his mouth twitched, and he hurriedly said, "Bixia, this cement is easy to say, but you still need to collect various materials and build a cement kiln, and these alone will be more than three days." ”。

Li Shimin frowned, pondered for a moment, and then said, "In this case, I will give you seven days, and the heating can be put off temporarily, and after seven days, you must make cement, Yunfei, the people of the Tang Dynasty and the border soldiers are inseparable from salt." ”。

Li Shimin's words were full of heaviness, Qin Yu heard this, nodded heavily, and then said, "Bixia, don't worry, the grass people will do their best to make cement." ”。

Li Shimin patted Qin Yu's shoulder with satisfaction, Qin Yu laughed a few times, and then said, "Bixia, Caomin still hasn't said anything about this." ”。

"Oh? What's up? Let's hear it. Li Shimin was slightly stunned, and then asked with a smile.

Qin Yu bowed, and then said, "Bixia, the grass people need to smelt iron ore to make heating, in order to prevent the crumbs from stealing into the mountains to steal iron ore, the grass people specially recruited a lot of security guards, well, it is the guard, who knows, more than a thousand people came at once, the grass people originally formulated a difficult test, but these people have passed." ”。

Li Shimin frowned when he heard this, obviously, no emperor likes the people below to gather men privately, and he is also a man who exceeds the bottom line of the emperor's heart, Qin Yu couldn't help jumping when he saw this, "It is said that a companion is like a tiger, sure enough." ”。

As soon as Qin Yu finished thinking about it, Li Shimin nodded, "Yun Fei wants to equip those guards with weapons?" ”。

Qin Yu hesitated for a moment, and then said, "Yes, Bixia, there are many fierce beasts in the mountains, and once a small crumb comes, the guards will inevitably be hurt if they have no weapons to defend themselves." ”。

"Okay, I agreed, but the number of guards will be limited to fifteen hundred, and if there are more, I will punish you." Li Shimin said unhappily and angrily, obviously, Li Shimin attaches great importance to Qin Yu, otherwise he would not agree to Qin Yu's request.

Fifteen hundred guards equipped with weapons are already considered private soldiers, and no powerful person dares to raise so many private soldiers, otherwise they will definitely be charged with rebellion, and it will not be a trivial matter at that time.

Qin Yu glanced at Li Shimin cautiously, just as Li Shimin looked over, seeing Qin Yu's action, Li Shimin immediately laughed, and the trace of unhappiness in his heart disappeared without a trace, only to see Li Shimin said with a smile, "Yunfei, what you said yesterday is from the heart?" ”。

Qin Yu was slightly stunned, then understood what Li Shimin meant, nodded solemnly, and said in a deep voice, "What the grass people say comes from the bottom of their hearts. ”。

Qin Yu does have the intention of changing the Tang Dynasty, and he has been doing so for this time, Qin Yu's words reveal sincerity everywhere, after Li Shimin heard it, he exhaled a long breath, and the only trace of concern in his heart disappeared in an instant, and then he shouted, "Okay, I believe in you." ”。

Qin Yu bowed, but he was stunned in his heart, "Strange, why does this Li Shimin trust me so much?" Aren't you afraid that I'll rebel? ”。

Qin Yu didn't know what Li Chunfeng told Li Shimin at the beginning, if he knew, it wouldn't be so strange, Qin Yu can maintain the Tang Dynasty and destroy the Tang Dynasty, the key is Princess Changle, as long as Li Lizhi marries Qin Yu, with Qin Yu's character, he will naturally not do that rebellious thing, not to mention, Li Chunfeng is really not wrong about this.

What's more, Qin Yu came to Datang for less than half a year, and he brought great changes to Datang, paper printing, Quyuan plough car, three-character scripture thousand-character text, soap and soap, tea and spirits, fire kang, sweet pot, potato corn, and just table salt, all of which came from Qin Yu's hands.

Li Shimin looked at it one by one, how could he not pay attention to Qin Yu, so he promised Qin Yu to equip the guards with weapons without asking much, this is because he doesn't want to chill Qin Yu's heart, so that Qin Yu can continue to contribute to the Tang Dynasty, and Li Shimin is not afraid of any 1,500 guards equipped with weapons at all, this is the fundamental reason, of course, Li Shimin's weight is greater.
