After Liu Yan received the news, he immediately rushed to the cement workshop outside the Aoshan Acropolis, only to see that Song Gongming had already rushed over first, and was discussing something around a wooden basket with Han Feng and several other craftsmen.

While waiting for the finished cement products, Song Gongming had already raised some money and grain, and mobilized it as the start-up capital for the cement workshop, and also contacted some businessmen, which paved the way for the sales of cement in advance.

Of course, regarding the specific situation of cement, Song Gongming did not reveal too much in advance, so as not to cause leakage.

When Liu Yan rushed to the cement workshop, Song Gongming and Han Feng hurriedly came to greet him, Liu Yan praised Han Feng and the craftsmen with a smile, and then began to enter the theme.

Liu Yan walked forward accompanied by Han Feng and Song Gongming, only to see that a large wooden basket had been filled with cement mortar, and everyone was waiting for the cement mortar to solidify just now.

Before Liu Yan arrived, Han Feng and Song Gongming started the experiment, wanting Liu Yan to check the results directly, after all, according to Liu Yan, the solidification time of this cement will be very long. However, it is obvious that Song Gongming and Han Feng miscalculated the time, and before it has solidified, Liu Yan has already arrived here.

After listening to the introductions of Song Gongming and Han Feng, Liu Yan carefully observed the wooden frame, and saw that the cement mortar was slightly different from the concrete mortar of later generations, there was no stone mixed in it, and the mortar in the wooden frame was relatively thin, not as viscous as the mortar of later generations. What plays a supporting role in the mortar is broken porcelain and other things.

Liu Yan first inquired in detail about the research and development process of this soil cement, and was very satisfied after listening to Han Feng's answer, knowing that Han Feng was developed and produced in strict accordance with his own methods, and there was no problem with materials, processes and processes.

So, Liu Yan asked, "How long has this basket of cement solidified?" ”

Han Feng looked at the special incense plate used to keep time next to him and said, "Lord Qiyu, it's been almost more than an hour. ”

Liu Yan nodded, and said secretly in his heart: "Time is not enough, and the concrete cement of the future generations will not be able to completely solidify for more than an hour, not to mention my soil cement, I will have to wait for a while!" ”

So, Liu Yan looked at the sky and saw that it was close to noon, so he said: "The time for condensation is not enough, it is estimated that this soil cement will have to wait a while to solidify, let's eat first, I'm already hungry." ”

Song Gongming and Han Feng hurriedly sent someone to prepare the meal.

In the living room in the cement workshop, Miao Shao, the commander of the guard battalion, brought a few soldiers over to set up a table, and put a few plates of delicious dishes on it, and Liu Yan beckoned Song Gongming and Han Feng to come over to eat and drink together.

Han Feng, on the other hand, was not worried about the soil cement that was solidifying, and insisted on staying at the scene and waiting.

Liu Yan saw that Han Feng was already immersed in it and couldn't extricate himself, so he no longer insisted.

Later, after Liu Yan ate and drank with Song Gongming and Miao Shao for a while, Song Gongming said: "My lord, after this cement solidifies, will it really be as hard as iron as you said, and the cost is low and the house is built quickly?" ”

"Of course!" 33

Liu Yan said with longing: "As long as the cement in our workshop can be mass-produced in large quantities, it will definitely have a huge impact, and not only will the building technology of Lingshanwei and Aoshanwei undergo earth-shaking changes, but also the houses that craftsmen can build will be bigger, taller and stronger!" Craftsmen were even able to build towering buildings dozens of stories high! ”

"Dozens of stories high!"

Song Gongming's eyes widened in disbelief after hearing this, he couldn't believe what Liu Yan said, and said secretly in his heart: "Even those tall towers and carved towers in various places are estimated to be not so high, that is, how many floors, more than a dozen floors, dozens of floors?" How is this possible! ”

However, looking at Liu Yan's confident appearance, Song Gongming had to believe that after all, some of the things that Liu Yan said and did before were many things that ordinary people couldn't do, or even dared to imagine, but Liu Yan did them one by one!

For example, who would have imagined that Liu Yan could leap from a general flag officer of Huoludun to a guerrilla general in just two or three years?

Therefore, even if Song Gongming couldn't believe it, he felt in his heart that Liu Yan would definitely be able to do what ordinary people couldn't, and this soil cement would definitely be successful.

Liu Yan and Song Gongming chatted for a while, and seeing that it was already past noon, they calculated in their hearts that the time should be about the same.

At this time, the two of them had eaten and drunk enough, and Liu Yan was ready to take a look at the cement in the wooden frame again.

Suddenly, Han Fengxing hurriedly ran over and said loudly, "My lord! Minister! It's done, the cement has succeeded, it's really rock-solid! ”

Song Gongming also looked at Liu Yan excitedly when he heard this, and said, "My lord, we have succeeded, there is really such a strange thing in the world!" ”

"Haha!"

Liu Yan laughed when he heard this, and said, "Let's go!" Let's take a look! ”

Everyone walked quickly to the wooden frame, Liu Yan looked at it, and saw that the cement in the wooden frame had basically solidified, like a large rock, which made Song Gongming and Han Feng and other craftsmen amazed, and the expression was as if they had seen a miracle of turning stones into gold.

Liu Yan stepped forward and knocked on the cement block, feeling that the hardness of this soil cement was barely qualified, and the setting time was also within the allowable range, but it felt a little brittle, and it seemed that the strength was still a little unsatisfactory.

Looking at the cement chips on his hands, Liu Yan sighed slightly in his heart, and said secretly: "It's okay to use this level to build houses, but if you use this kind of cement to build city walls and other military facilities according to my expectations, it will be a bit insufficient, this degree of hardness is still a little worse, and the enemy's trebuchet or even a large-scale rain of arrows can hurt the cement wall." ”

So, Liu Yan said to Han Feng: "This soil method cement is considered a success, but there are still some small flaws that need to be improved immediately by the craftsmen of the cement workshop." ”

Hearing this, Han Feng hurriedly said, "Please make it clear." ”

"Hardness!"

Liu Yan broke the cement block with his hand, then showed Han Feng the cement crumbs in his hand, and said: "The hardness of this soil cement is still not enough, and the workshop must find a way to solve it as soon as possible." My standard is four words: rock solid! It's to be truly rock-solid. ”

Han Feng nodded heavily when he heard this, and said, "Don't worry, my lord, I will do it immediately, immediately mobilize manpower, and work day and night to improve the cement process." ”

Afterwards, Liu Yan inspected all parts of the workshop accompanied by everyone, and then returned to Jimo Camp City satisfied.

A few days later, Liu Yan received an urgent report from Han Feng again that the hardness of the soil cement had been improved, and asked Liu Yan to send someone to accept it.

Liu Yan was very happy to hear the news, and personally rushed to the cement workshop outside the Aoshan Acropolis, only to see a piece of solidified cement placed in the open space, Han Feng, Miao Shao, Song Gongming and several people surrounded Liu Yan to watch, a craftsman in front of Liu Yan, directly smashed it with a sledgehammer, only to hear the sound of "bang", the cement block only dropped a few chips, and the whole was still intact!

Seeing this, the surrounding craftsmen immediately cheered, and the faces of Han Feng and the craftsmen were also full of pride, this was the result of everyone's improvement day and night for many days, which was enough to make everyone proud.

Liu Yan was also very happy to see this, although the improved soil cement still cannot be compared with the concrete of later generations, but in the late Ming Dynasty it was already a miracle, and it could fully meet the requirements of Lingshanwei and Aoshanwei construction.

"Good!"

Liu Yan said loudly in front of everyone: "All the craftsmen who participate in the research and development and improvement of soil cement will be rewarded with five taels of silver each, and the monthly salary will increase by one percent!" ”

As soon as the words fell, the crowd cheered again. Many craftsmen were shouting "Long live the adult", and Han Feng, Song Gongming and others didn't feel anything wrong, and even shouted together.

After that, Liu Yan said to Song Gongming and Han Feng: "Immediately organize people to build a model house outside the Aoshan Acropolis, and the construction method will be according to the method I gave you before, and it will be watered with cement!" This model house has to be built with at least three floors, understand? ”

Han Feng nodded excitedly, knowing in his heart that the house he was going to organize and build would be the first cement house in the world, which was a great opportunity to become famous! And once this house is built, it is the best publicity for the cement workshop, which can directly open up sales for cement.

On the same day, Han Feng led people to demarcate a vacant land in the north outside the Aoshan Acropolis, and then mobilized people to work day and night.

Only half a month later, a rather exquisite three-story house rose outside the Acropolis of Aoshan, this house was built with earth cement, very strong, as if it was a house carved out of stone. And the speed of construction of this house is unimaginable, a three-story house was built in just fifteen days, which is enough to surprise anyone.

Song Gongming, who rushed to hear the news, and all the craftsmen in the workshop were amazed.

Liu Yan, who then rushed to hear the news, was also very satisfied, and immediately ordered the cement workshop outside the Aoshan Acropolis to start producing cement at full capacity and do a good job in the reserve of cement.

"When the time comes, the cement can be used in the major projects of Lingshanwei and Aoshanwei, which can not only greatly improve the quality of construction, but also save a lot of time, time is money!"

Liu Yan thought secretly in his heart, and also breathed a sigh of relief: "Now, as long as the cement is sold, it will be another source of income, and you can do more big things." ”

After receiving Liu Yan's instructions, Song Gongming immediately said that he would immediately organize people to allocate money and grain to ensure the smooth operation of the cement workshop.

Liu Yan gave another order to everyone, and then returned to Jimo Camp City.

However, before leaving, Liu Yan pointed to the cement house in the north of the city and said: "Someone must be sent here to protect it, don't let irrelevant people enter or leave for the time being, and don't let anyone get the news." Cover the outside of the house with wooden planks and other things, build a fence around the house, and send people to guard it. ”

Everyone was puzzled, and Song Gongming directly asked Liu Yan's intentions, so as to do things more beautifully.

Liu Yan said with a smile: "I have a lot of use for this house, you just have to wait for my news!" ”

Some people died, but not completely......
