Yang Heng didn't expect that some ministers came quickly, and the first ones to come were naturally those old guys, Cheng Goblin, veterans like old fools.

"I said eldest nephew, you see that we don't have much copper money in our family, or do you support my family with a hundred and ten bags of cement?" This is Cheng Fairy, counting him as the most shameless.

"It is impossible to give away cement, this is a limited purchase, not only the purchase limit, but also the registration of the amount of use, if your family bought ten bags, only nine and a half bags were used, and you still need to be responsible for transporting the rest back to the cement factory, otherwise Your Majesty will put you guilty." Yang Heng told jokes to the old goblin, but he suddenly thought, this is not a joke, what is this, cement, once it is discovered by foreign countries, then this is a strategic resource that endangers Datang, building a city, and building some military facilities is the fastest and most sturdy.

"Purchase limit, purchase limit, no, I want to enter the palace immediately, and I want to report to His Majesty." Yang Heng didn't care about accompanying the old goblin, so he turned around and wanted to leave. "Virtuous nephew, what are you? Ah, the old man is also going to enter the palace, such an important material, you only use it to make these things, go, go into the palace together. The old goblin also reacted, in fact, he was reminded by Yang Heng's words, if it was Li Er's order, he only needed to obey it, but Yang Heng's words, he needed to turn his brain a few times to prevent being set by Yang Heng, in fact, Yang Heng didn't like the set, but these old guys liked the set, this is a typical villain's heart.

"Your Majesty, the minister has his own music." Seeing that the old goblin took the lead, Yang Heng had no choice but to stand aside, "You two are, how could you get together to see me." Could it be that there is something wrong with the digester? Still is. ”

"Your Majesty. Chen suggested that the biogas digester project should be suspended and the use of cement should be re-evaluated, which he believes is not the only use. "Ao, Cheng Aiqing, what is the use of this cement, you tell me about it?" Li Er looked at Fairy Cheng with interest, when did this old killer pass by so much, could it be that today's sun came out of the west?

"Your Majesty, look. This is a piece of cement residue that I picked up from the corner of Yang Yuma's house, and the minister wanted to break it off from the wall of his house, but with the minister's strength, he didn't break it off, so he found such a piece of residue. Yang Heng took a look, this old goblin, when did he pick up this piece of slag from under the wall, this piece of slag is half the size of a fist, because of the bricklayer, they don't know much about cement, so they waste a lot of cement. It's all such a piece of slag, and Yang Heng doesn't bother to let them clean it up. It was just laid on the wall, buried with soil and then leveled in the ground, and somehow it was picked out by this old goblin.

"Let me see, this is even stronger than stone, Yang Heng, tell me, is the cement so strong, what is it for?" "Back to His Majesty, the cement is indeed so strong, and as long as the cement has a certain amount of sand, or even gravel, it will be quite strong within a day after use, and it is the best building material for building cities and paving roads, and even repairing sewers and building houses are very good materials, but unfortunately, the output of the cement factory in Chen's house is still low, and it can only be used to build some biogas digesters, that is, the biogas digesters are set more, and the output of cement can not keep up." Yang Heng said with some regret.

"The yield is small, but I found that your home is all cement, and if your words are not true, I will condemn you to a crime of deception." "Yes, Your Majesty, you want to treat this kid as the crime of bullying the king, there is such a good thing not to take out and use, but just to build a biogas digester, and it is so expensive, the minister feels a little unbearable." Cheng Fairy ignited the fire.

"I said General Cheng, that's not what I said, do you know the benefits of this biogas digester, do you know the Tao, in addition to these things in your eyes, do you know the other benefits?"

"What's the benefit, it's just boiling water, lighting the lamp, and the old man just found that the toilet was good, but it had to renovate the whole yard, and even burned the fertilizer." Cheng Fairy said indifferently.

"General Cheng, are you sure that the fertilizer is burned, first of all, your home will be very clean, you must know that the road is used in the toilet at home, the smell is very big, and this biogas digester is no smell, even if there is a smell, that is, there will be a smell of rotten eggs when there is occasional air leakage, but the fertilizer has increased many times, and the biogas slurry and biogas residue fertilizer field, it will also eliminate some insect pests, this biogas slurry biogas residue fertilizer field can also improve the soil, so that the grain production can be increased, do you say there is any benefit." Yang Heng said to Fairy Cheng very angrily.

"This is true, why didn't you say it earlier, do you know the way of your majesty, or else, treat this kid for one more crime." This Cheng goblin began to make trouble unreasonably, maybe this is his way of being a minister, maybe his intention is, the emperor, although this kid is your son-in-law, there is still a reward to have, and it can't just be done.

"Okay, don't worry about this biogas residue and biogas slurry first, Yang Heng, now you send a few bags of cement into the palace first, by the way, what else do you need, it's sand and stones, right, you can also pull these in together, come here, go to the Ministry of Soldiers, the Ministry of Industry, and ......" Li Er's series of orders were issued, just to let people come to see the role of this cement.

And Yang Heng was waiting for this order, when Li Er's order was reached, he quickly left the palace, and then entered the palace with several truckloads of cement stones, but for safety, these things were stabbed many times by the guards with spears before entering the palace, which directly led to a lot of cement powder being sprinkled along the way, and it was these cement powders that led to an important and heartbroken character.

"Okay, Yang Heng has arrived, let's start now, Yang Heng, just follow your design." When Yang Heng arrived, a group of veterans were already waiting here, and they were even asking each other what the emperor had called them to do, and the only one who could know the way was Cheng Fairy, if they wanted to ask something from Cheng Fairy's mouth, it would basically be regarded as the sun coming out of the west, so they didn't ask Cheng Fairy directly, making Cheng Fairy feel very bored there.

When Fairy Cheng was about to strike up a conversation, Yang Heng just arrived, "Boy, why are you here so soon." Cheng Fairy asked Yang Heng softly, even with a little reproach, what, you also have an opinion when I came quickly, and then looked to the side, and then understood that he was actually excluded from the circle.

"Hello old generals, this is cement," "Ha Lu Ha "I've seen the Emperor." There was a dry laugh outside, followed by the voice of a eunuch, what, the emperor is here, Yang Heng felt a little surprised, he has been in this world for a few years, although it is said that Li Yuan was the emperor when he first came, but since Li Er became the emperor, he has not heard his movements, according to Yang Heng's YY novel in his previous life, he is now busy making children, but why did he come out today, in fact, Li Yuan did not come out, but he did not appear in the world, this is not today, but the cement powder is attracted to it. It can be seen that the new thing is indeed attractive.

"I've seen my father (Emperor Taishang)." Everyone saluted Li Yuan at the same time, "Okay, okay, don't be polite, this is my grandson-in-law, why did you make this thing, you continue, you continue, I'm just curious, come and take a look." ”

"Yang Heng, you continue." "Guys, come here, you take a shovel, you go and carry water." What, this is also done by yourself, there happened to be guards on the side, Yang Heng directly commanded the guards to start the work of mixing cement, one will mix sand, one will mix stones, one will pour cement, and then dig a pit in the middle and pour water into it, and then Yang Heng glanced around and found that this place was in the courtyard of a large hall, and it happened to be a place to stay.

"Your Majesty, let the minister harden this ground, and you won't be afraid of rain and mud in the future." "Yes, I've got it." Li Er said indifferently, it is true that there is a lot of mud in this place, Yang Heng observed it very well, and Li Er also likes to receive some officials in this place, originally he wanted to lay the slate, if it is hardened, then the slate does not need to be paved.
