Li Shimin nodded with satisfaction, and when he thought of the kind of heating that Qin Yu said in winter, which could keep warm all day, Li Shimin was happy in his heart.

With heating and no coal, just as it is difficult for a good woman to cook without rice, Qin Yu thought about it, and then said, "Bixia, the grass people want to ask Bixia for something." ”。

"Oh? What's the matter? Hearing this, Li Shimin looked at Qin Yu with curiosity and asked.

"The grass people want to ask for the mineral rights of the coal mines in the mountains to the south." Qin Yu bowed in response.

"Coal mines? What is it? What are mineral rights? Li Shimin was slightly stunned and asked with some confusion.

"Back to Bixia, this coal mine is a coal mine, a kind of stone that can be burned, and the mineral right is that no one else is allowed to mine this coal mine except for the grass people." Qin Yu wanted to laugh in his heart, but he didn't dare to laugh, so he hurriedly bowed his head and said.

"Stones? Stones that can be burned? Li Shimin looked at Qin Yu with a smile and a smile, shook his head helplessly, and then said, "You kid thinks about some mess all day long, since you want it, then I will give it to you." ”。

"Thank you bixia, I will ask bixia to make a will later, so that the grass people can also be justified." Qin Yu was overjoyed when he heard this, and hurriedly bowed down and bowed.

Qin Yu did this in order to prevent others from going to the mountains to mine coal after knowing the benefits of the coal mine.

As for making money from coal mines, Qin Yu also has some ideas, but at present, the probability of Datang making a lot of money from coal is not great, because the demand is there, but Qin Yu is really ruthless enough, and directly draws that mountain range into his own hands. After the coal was known, there was no way to mine it, who told Li Shimin to give the coal mine to Qin Yu.

Seeing that Qin Yu was serious, Li Shimin shook his head helplessly and sighed, "Okay, I will give you an order, but Yunfei, you have to make this heating for me as soon as possible, otherwise." I will punish your sins. ”。

"Bixia rest assured that the grass people will do their best." Qin Yu replied with a smile, to be honest, Qin Yu really didn't worry about the heating not being able to be made, it was nothing more than some pipes and radiators. It's a bit troublesome to connect the pipe threads, but it's not a big problem. Just get a gear hobbing machine. If you can't get it automatically, you just need to get a manual one, and it's not a big problem.

Li Shimin nodded with satisfaction, Qin Yu brought a lot of surprises to Li Shimin, and this time it was a big surprise, especially this year's winter seemed to be earlier than in previous years. It must be an unusual winter, and with the ondol heating, Li Shimin is relieved.

At this time, Li Shimin suddenly thought of something, and then asked. "Yunfei, how many days will it take for sweet potatoes?"

Qin Yu nodded, "Bixia, the stems and leaves of this sweet potato potato are already yellow, and they have to be dug up in the next two days, but because of the weather, they can't wait longer, otherwise they will be broken." ”。

Li Shimin's eyes lit up when he heard this, and he immediately said, "In that case, it's just right, I'll go and see if the sweet potatoes are as amazing as you said." ”。

"Yes, Bixia." Qin Yu is naturally not worried about the yield of sweet potatoes, Li Shimin wants to see it today, Qin Yu doesn't care, and then bowed down and said.

Li Shimin smiled slightly, and then instructed Yang Gonggong, "Gather all the ministers and go to Qingfeng Ju with me to take a look at the sweet potatoes." ”。

"It's Bixia." Yang Gonggong bowed down and finished speaking, and left in a hurry, Li Shimin's words were simple, but if the Manchu Dynasty civil and military were summoned, it would not be solved in a moment and a half, and a large number of people could only be dispatched, otherwise there was really no hurry.

The emperor traveled, Yu Linjun naturally had to accompany him, Qin Yu saw Hou Changqing again, this kid was still the same as a few days ago, he didn't give Qin Yu any good face, Qin Yu saw this, pouted his lips disdainfully, and suddenly Hou Changqing was angry, which could be seen from his constantly undulating chest.

An hour later, the Manchu Dynasty civil and military gathered in the palace, Li Shimin gave an order, and the long line went towards Qingfeng Ju, which can be regarded as causing a sensation, and the people of Chang'an stopped to watch, of course, no one dared to block the way, and blocking the road was not looking for death.

Qingfeng Ju, the dog who guarded the door saw the long line at a glance, Qi Qi was stunned, the dog egg's eyes were better, and he pointed to Li Shimin's carriage and said with some trepidation, "Dog leftover, look, is that Bixia's carriage." ”。

Gou Yu looked at it carefully for a while, then he was stunned, and hurriedly shouted, "Quick, inform Madame, Bixia is here." ”。

When the dog heard this, he hurriedly called a maid, and said in a hurry, "Quick, quickly inform Madame, Bixia is here." ”。

After the maid was slightly stunned, she immediately ran towards the back house, and it didn't take long for Cheng Lingyun and Cui Mengyao to learn the news, and they were shocked, the emperor was coming, and he was originally going to arrange it, but now where is there still time, Cheng Lingyun finally gave up the arrangement, and came directly to the bottom of the mountain with Cui Mengyao to wait.

After the team arrived, Qin Yu hurriedly ran to the front to lead the way for Empress Li Shimin's eldest grandson, and saw the panicked Cheng Lingyun and Cui Mengyao at a glance, and then said in a low voice, "It's okay, Bixia is here to see sweet potatoes." ”。

Cheng Lingyun and Cui Mengyao naturally knew about sweet potatoes, especially Cheng Lingyun, who still looked at Qin Yu with some anxiety when she heard this, Qin Yu cast a reassuring look at Cheng Lingyun, and then looked at Li Shimin and the eldest grandson Empress who came over.

"The concubine meets Bixia, the queen." Cheng Lingyun and Cui Mengyao all stepped forward and bowed in worship.

Li Shimin's eldest grandson Empress smiled and nodded, at this time, Li Shimin was stunned when he saw Cui Mengyao beside Cheng Lingyun, Cheng Lingyun saw this, and hurriedly said, "Bixia, this is the cousin of the concubine." ”。

Li Shimin nodded, then looked at Cui Mengyao, frowned for a moment, and then looked at Qin Yu, but it was Li Shimin who found that Cui Mengyao's state was a little wrong, Qin Yu naturally knew what Li Shimin's eyes meant, and hurriedly bowed down and smiled, "Bixia, queen, please inside." ”。

Li Shimin nodded, and then took the hand of Empress Changsun and walked up the mountain, followed by Qin Yu, Cheng Lingyun, Cui Mengyao, and then the Manchu Dynasty civil and military.

Of course, Cheng Yanjin and Qin Qiong are among them, but at this moment, the faces of the two are full of worry. I'm afraid that something will go wrong with this sweet potato potato, you must know that now the Manchu Dynasty is both civil and military, and it may be difficult to intercede at that time.

Coming to the place where sweet potatoes and potatoes are planted, Li Shimin saw five conspicuous corn plants at a glance, and was stunned for a moment, Qin Yu saw this, and hurriedly said, "Bixia, this is exactly what the grass people said. ”。

When Li Shimin heard this, he stared at the corn for a while. Only then did he nod, and then came to the place where the sweet potato potatoes were planted, looked at the sweet potato potatoes whose stems and leaves had been yellowed, took a deep breath, and then spoke. "Let's start digging."

The eunuchs in the palace immediately stepped forward and carefully used their hands to stir the soil on the sweet potatoes one by one. I'm afraid of breaking it a little. was punished by Li Shimin, if these eunuchs didn't know the importance of this thing in such a big scene, they would have ghosts.

When the first sweet potato appeared in front of everyone, Li Shimin and a group of civil and military ministers were quite calm, and after the first potato was unearthed, it was the same.

When the sweet potatoes and potatoes were unearthed one after another, everyone could continue to maintain their composure. But when the basket with sweet potatoes and potatoes was full, everyone suddenly became calm, one by one, you look at me, I look at you, and they all gasped.

Li Shimin exhaled a long breath. Before, he was worried that the yield of this sweet potato potato was too low, but now it seems that Qin Yu lied at all, where is this ten stones, at least twenty stones, Li Shimin nodded with great satisfaction, and when a piece of sweet potato was dug out, Li Shimin opened his mouth and said, "Go and calculate the yield." ”。

"Yes, Bixia." Seeing Li Shimin looking over, Dasi Nong hurriedly bowed down and answered, and then led someone forward to calculate the yield of sweet potatoes.

After a stick of incense, Dasi Nong hurriedly ran to see Li Shimin, bowed down and said excitedly, "Qi Qi Bixia, after the minister calculates, the yield per mu of sweet potatoes can reach 80 stones, and the yield of potatoes can reach 60 stones per mu. ”。

"Sss After everyone at the scene heard this conclusion, except for Qin Yu, they all gasped, even Empress Li Shimin's eldest grandson.

Li Shimin asked with some excitement, "Really?" ”。

Da Sinong hurriedly bowed down and responded, "Back to Bixia, but it is like this, the minister has calculated many times, and it is indeed possible to achieve this kind of output." ”。

"Okay, okay." Li Shimin let out a long roar, and then all the civil and military officials bowed down and said, "God bless the Tang Dynasty, long live my emperor, long live, long live." ”。

"Haha." Li Shimin looked up to the sky and smiled very happily, Qin Yu had the heart to tell Li Shimin that this sweet potato potato still needs to be detoxified to ensure this yield, but looking at the current situation, Qin Yu still wisely closed his mouth.

Qin Yu naturally knew that it was not a good time to say this at this time, and it was not too late to say it when there was no one.

At this time, Li Shimin looked at Qin Yu with an excited face, and said, "Yunfei, you have made a great contribution to Datang. ”。

Qin Yu smiled and bowed down and said, "Bixia, this is a matter within the grass people's business. ”。

Li Shimin patted Qin Yu's shoulder heavily, and then said, "What a good thing, Yunfei, I once said that if this sweet potato can succeed, then I will allow you to marry Mrs. Zuo, and I will also promise to marry you, and my words count." ”。

"These are far from your merits, I will make you the founding county prince today, hereditary replacement, this Qingfeng Ju has turned five hundred miles from the south into your fiefdom, you want to cultivate the land, you want to open a mine and open a mine, it's all up to you, how?"

"Sss The civil and military officials gasped in unison, Li Shimin's reward is simply too big, and the knighthood is amazing enough, but this is not the end, Li Shimin actually directly gave Qin Yu a place five hundred miles away, and he can do anything.

What is this called, private territory, not to mention those founding heroes, even those princes have never gotten such a big place, let alone such a big power, but Qin Yu got it all at once, how could everyone not be shocked.

Qin Yu was stunned when he heard this, but seeing that Li Shimin's expression didn't look like a lie at all, after swallowing his saliva heavily, he hurriedly bowed down and said, "Thank you Bixia, the grass people will do their best to repay Bixia Longen, long live my emperor, long live, long live." ”。 (To be continued......)
