Mo Xiangsi immediately understood what Ji Yun meant, and he sneered in his heart: "What this kid means is to use this iron sand mud to build a siege city, hey, take this precious thing to do business with me?" Are you stupid or am I stupid?"

However, he was extremely respectful and kind: "It is said that the whole body of the county king's mansion is made of iron sand mud, and even the road leading to Yunzhou is made of iron sand mud, and the hardness of this mud is amazing, but... It is extremely expensive, and without the vigorous craftsmen of at least hundreds of Gewuyuan, it is impossible to mass produce it. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo”

He is already blocking Ji Yun's mouth, after all, Ji Yun is the king of the county, and the official is a high-ranking person who crushes people to death, in case someone really wants to buy and sell, he will have to turn his face, and it is unwise to turn his face with such a county king who does not seem to be strong in the background but is very tough.

"Iron sand mud is expensive and difficult to make, but... Recently, the king of this county has researched a kind of thing, which is similar to iron sand mud, and its strength is not as good as iron sand mud, but if you add some iron bars or iron rods and the like, the hardness is better than that of iron sand mud!"

Mo Xiangsi was slightly stunned, and immediately admired and praised him: "Xiaohou has long heard that the county king is wise, but he doesn't know what the county king has studied..."

"I call it cement, Mo Hou Ye, please take a look!" Ji Yun pointed to something on the ground that looked like grass and wood ash, "This is cement, it is simple to make, the materials can be seen everywhere, this slate is made of cement and sand and gravel, Mo Hou Ye cultivates to a high level, you might as well try its hardness!"

Mo Xiangsi looked down for a while, then frowned and grabbed the stone slab, looked at it, and then put it down, a look of surprise already appeared on his face.

Ji Yun saw that he didn't make any moves, but he knew in his heart that this person had actually tested the hardness of this stone slab inadvertently.

"Sure enough, the cultivation is extremely high, but I don't know what the specific cultivation is!"

"Awesome!" Mo Xiangsi finally spoke, "But I don't know that the king of the county... cement..."

"Hou Ye is wise and clever, he must have seen the value of this thing, if the city wall of Luoshui City is made with this thing, not to mention ordinary demon barbarians, even if he cultivates to a profound demon barbarian, he can't break the city wall, and without the hidden worries of the city wall, I think Mo Hou Ye will have to worry too much!"

Mo Xiangsi took a deep breath, but did not speak.

"Ma Yue, you can make another slate in front of Mo Houye!" Ji Yun chuckled in his heart, and it could be seen that Mo Xiangsi was a little unconvinced.

Ma Yue began to make it in response, and with the experience of one time, this time the speed was extremely fast, and by the time the craftsman dried, the whole process was less than dozens of breaths.

Mo Xiangsi glanced at the sword like a dream and the sword like a fantasy behind him, the two stepped forward, raised their hands and pinched it, then glanced at Ji Yun meaningfully, and nodded towards Mo Xiangsi.

"These three people don't show how much damage they have to this stone slab, they just pinch it, obviously covering up their cultivation!" Ji Yun suddenly understood, but in front of such a foolish man as himself, he still had to hide his cultivation, were these people all cautious people, or were there other reasons?

"How does the county king want to trade?" Mo Xiangsi was moved, if the city wall of Luoshui City was cast with such cement, it would really save a lot of financial, manpower, and material resources, and more importantly... Energy!

"Let's not talk about money, what I want is very simple, food!" Ji Yun didn't beat around the bush, and directly stated the purpose.

"Food?" Mo Xiangsi was stunned for a moment, but he immediately understood, he himself is a master of the Dao Realm, and he has long been convinced that he can not eat for a long time, but this Ji Yun does not have that ability, and when he came to the Junwang Mansion today, he also found that Ji Yun's personal soldiers are all martial realm monks, and they still need to eat, so they naturally need food.

"Well, let's talk about it in detail!" Mo Xiangsi nodded.

Ji Yun thought for a while: "The price of a bucket of iron sand mud is five hundred taels of silver, right? If five hundred taels of silver is used to buy grain...... Hehe, then what does Mo Hou Ye think, how much is my cement bucket worth?"

Mo Houye's face suddenly became ugly, and he said honestly in his heart, the cost performance of this cement is much stronger than that iron sand mud, although the hardness is slightly inferior, but the manufacturing materials are simple.

Iron sand mud requires a lot of iron ore, and this alone raises the price.

Ji Yun looked at his face, and sighed secretly in his heart, now is not the time to pit people, solving everyone's food and clothing is the key, and then waved his hand: "In this way, I will give you a bucket of cement that is only five taels of silver, according to the price of rice in my Great Qian Dynasty, one tael of silver can buy one stone of rice, which is one hundred and twenty catties of rice, and my bucket of cement, even if it is six hundred catties of rice, how about it?"

"Five taels!?"

Ma Yue was taken aback.

"Five... Five taels?" Mo Xiangsi thought he had heard it wrong, and looked at Ji Yun in shock, this person was kicked in the head by a donkey, right?

"That's right, it's five taels!" Ji Yun smiled indifferently, "The prerequisite is to bother Mo Hou Ye to find some cooks for my fiefdom, don't worry, my fiefdom is no longer a peerless land!"

"No problem!" Mo Xiangsi was overjoyed, a bucket of iron sand mud is indeed worth five hundred taels of silver, of course, it is not worth so much money in itself, it is because of the production process and the value of the craftsmen, but this cement... Ji Yun actually only gave five taels, this is simply pie in the sky!

"One bucket of cement, 600 catties of rice, the rice on the market is one sack of 200 catties, that is, one bucket of cement and three sacks of rice!

"That's enough, so be it, I'll start making cement for you right away, and you will pick up the goods in three days!" Mo Xiangsi was overjoyed, but Ji Yun was also smiling proudly in his heart.

It is really not difficult to make cement, just now these are made by a strong heavenly craftsman, when it needs to be mass-produced, he can directly let the soldiers build an earthen kiln, the high temperature of more than 1,000 degrees, it is very simple to control by a strong heavenly craftsman.

Even if they don't understand what more than 1,000 degrees are, they can compare it with boiling water, which is 100 degrees, and with the ability of a strong craftsman, they can figure out what a high temperature of more than 1,000 degrees is.

As for raw materials, limestone and clay are everywhere, and cement does not have a high demand for iron ore.

One bucket, that is, a slightly larger watermelon, can be exchanged for 600 catties of rice, which is a good deal!

Besides, Ji Yun has long had the idea of promoting this cement, but it is not the time yet.

Just the pile of cement around him is enough for three buckets.

"Master Mo, I still need to be reminded of one more thing, the number of this cement... Belch... That is, the less sand you mix, the harder it will be after condensation, the denser the iron bars inside, and the stronger the same cast thing, and if you want to build a city wall with cement, you will need a lot of cement!"

"Thank you for the reminder, but five taels of silver......" Mo Xiangsi didn't say anything more, and added in his heart: The price of five taels of silver is so low, even if the demand is large, it is nothing.

"King Jun, can you make this cement... Sell it to Xiaohou?" Mo Xiangsi looked at the cement on the ground for a long time, pondered it for a long time, and asked in a low voice.

"Sell it to you, it's not a secret, the king of this county can't for the time being!" Ji Yun directly vetoed.

Mo Xiangsi glanced at Ji Yun slightly, a strange light flashed in his eyes, and he didn't ask any more.

"I'm afraid... The warehouse in my fiefdom is not enough to hold grain!" Ji Yun didn't pay attention to Mo Xiangsi's reaction, he was still thinking about exchanging cement for grain in his heart, and such a thought suddenly popped up in his mind.

Luoshui City is so big, and if you want to build a cement city wall, the cement required is ......

He didn't dare to forget it.
