Wang Yin walked around the village, and after finding a large enough open space, he stopped, and with a wave of his hand, a hill-like pile of potatoes appeared on the ground, and at a cursory glance, it was afraid that it was more than 100,000 catties.

"These potatoes are not just for your village," Wang Yin explained, seeing everyone looking at him in shock and confusion: "After you finish planting in your village, stop people from sending them to the rest of the villages, and this time I will let all the families in Lantian County plant potatoes." ”

"Okay, Grandpa Jun, don't worry, we will definitely make it beautiful for you!" When the villagers heard this, they immediately patted their chests and reassured.

"Erniu, you go to the village to find some people to come and guide them on how to plant," Wang Yin instructed Wang Erniu: "By the way, by the way, send someone to pick some vegetables from the greenhouse and send them to the women." ”

"Whoa!" Wang Erniu answered, then turned around and saluted Li Shimin, and ran back to the village to find someone.

Immediately, Wang Yin greeted the people in Xiashui Village and left with Li Shimin and Cheng Lingxue.

"I don't see it, your kid is quite big." Li Shimin turned his head to look at Wang Yin and said, "Didn't you say you wanted to plant cotton before?" Why did it suddenly change to potatoes? ”

"Of course, we must solve the problem of eating first," Wang Yin spread his hands: "And cotton is not easy to grow this season." ”

Wang Yin didn't ask if the cotton in the system could grow in winter, and it was estimated that even if it could grow, the yield would shrink.

Cotton is different from potatoes, even if the yield of potatoes is reduced, it is enough to eat, and if the yield of cotton is reduced, it will directly affect the output of cotton cloth.

How to promote at a low price when the output is low?

After all, the demand for cotton cloth is much higher than that of potatoes, so I can't let them grow cotton all the time, right?

"Isn't there a greenhouse?" Li Shimin was puzzled.

"What about the entire Lantian County," Wang Yin glanced at him: "Do you want to exhaust me or do you want to exhaust Duan Lun and them?" ”

Hearing Wang Yin say this, Li Shimin laughed for a moment, and then stopped saying anything.

The three of them continued on their way and finally stopped at the gate of the cement factory.

"Why did you come here all of a sudden?" Looking at the col in front of him, Li Shimin was puzzled.

"Counting the days, this first batch of cement should be almost out," Wang Yin said, and walked in from the path next to the boulder.

After coming to the valley, Wang Yin looked at it, the cement kiln had been built, and it was spewing smoke at the moment, and it was obvious that it had been put into production. Not far in front of the kiln, Duan Lun was sitting around with a few people and didn't know what to do.

Looking at Duan Lun's figure in front of him, Wang Yin sighed in his heart: I just saw Duan Lun in the Ministry of Industry two days ago, and now he has come to the mountains again, tsk, this busy energy is about to catch up with Uncle Du Du...

"Duan Lun," Li Shimin called lightly.

"See Your Majesty, I've seen the gods!" When everyone heard the sound, they looked up and saw that it was the two top bosses of Datang, and hurriedly bowed and saluted.

"Excuse me," Li Shimin waved his hand: "What are you doing around?" ”

"Back to Your Majesty, this cement came out, and a few days ago they got a sample according to the instructions of the immortals." Duan Lun pointed to the cement slab on the ground and said.

Li Shimin looked down and saw a blue-gray stone-like thing on the ground, but its surface was slightly rough and did not have the luster of a stone.

"This cement can be made into stone?" Li Shimin turned his head and asked Wang Yin.

Before, Wang Yin just said that he wanted to build a cement factory, and then gave Duan Lun their drawings to let them start construction, and did not mention what the cement was for.

Adhering to the principle of 'what Wang Yin took out must be a good thing', Li Shimin naturally agreed, but before the cement came out now, they didn't know what the cement was for...

Now seeing that cement can be made into something like stone, Li Shimin will inevitably be surprised.

"Not to make it into stone, but ... Forget it, you just know it's sturdy anyway. Wang Yin explained to him.

"How sturdy?" Li Shimin's eyes lit up when he heard this.

"Just try it." Wang Yin took out a sledgehammer and handed it to Li Shimin.

Seeing this, Li Shimin took the sledgehammer and asked Duan Lun and them to retreat to the side, and then picked up the hammer and smashed it down.

You must know that Li Shimin is the emperor immediately, and his kung fu is naturally good, although he can't do it when he is an emperor now, but he usually exercises occasionally, and his strength is still not small.

"Bang!"

Li Shimin smashed down with a hammer and directly bounced the hammer away, Li Shimin's arm was also shocked enough, Li Shimin shook off the numb arm that was shocked, squatted down and stared at the cement slab carefully.

It doesn't matter if you don't look at it, you will be shocked when you see it: the place where the cement board and the hammer come into contact is only slightly wiped off a little skin, if you don't look carefully, you are afraid that you can't find it, you must know that the strength you used just now is not small!

"It's so sturdy?!!" Li Shimin was suddenly surprised.

Wang Yinxin said: Nonsense, if it is ordinary cement, it will definitely not work, but we are a systematic black technology product, can it be the same? If it weren't for the backward production conditions, I'm afraid you won't be able to smash a white mark if you're tired to death...

"Good! Very good! Li Shimin then paced back and forth excitedly: "If this thing is used as the wall of Chang'an City, wouldn't it be impregnable?!" ”

Thinking of this, Li Shimin couldn't help but sigh: If there was such a thing back then, why did I sign the Weishui Alliance with the Turks?

"Lao Li, wake up," Wang Yin grabbed Li Shimin, who was excited, "I didn't say that this thing was used to make a city wall." ”

"Not a city wall?" Li Shimin's heart suddenly burst into his heart when he heard this: "Then this cement... ”

"Remember what I told you about building roads?" Wang Yin glanced at him: "This cement is used to build roads." ”

"Isn't it a waste to pave the way with such good things?" Li Shimin said unwillingly.

At this moment, he is not only unwilling in his heart, but he almost wants to scold his mother: Made! Such a good thing, you kid actually used it to pave the way? Are you a loser?! Aren't you afraid that your father will find out and kill you? Well, this kid doesn't seem to have a father。。。。。。

"Alright, you guys get busy." Wang Yin waved his hand at Duan Lun and the others and sent them away.

Duan Lun and the others saw that the immortals had spoken, so they naturally left obediently. Although they also want to hear what Wang Yin is going to say next...

"You know a ball!" After seeing Duan Lun and them leaving, Wang Yin spoke.

After all, Comrade Lao Li, who would have done such a thing in front of Duan Lun and them, is very faceless, and Wang Yin is still very caring...

If Duan Lun knew Wang Yin's thoughts, they would definitely burst into tears of gratitude: the immortals are so considerate! If you are seen by yourself and others, Your Majesty will be cut like this, and I am afraid that I will not be able to live in the future...
