After Lu Yan had a heart-to-heart talk with Zhuge Liang, he finally tied Zhuge Liang to his own warship.
"As long as Kong Ming can grow up quickly and with his abilities, I should be able to retire early, right?"
Lu Yan imagined the magical life after he retired at the age of forty, humming an unknown ditty and walked towards his mansion.
Huang Xu, Lu Xun, Chen Dao and others have all entered Taixue to study.
Guo Yi has also been studying hard under Guo Jia's "force" recently, preparing to be admitted to Taipei University next year.
The former lively Cavalry General's Mansion now seems a bit deserted without the most noisy guys.
Huang Wudie has also grown up and turned into a graceful and graceful girl.
Hearing that Huang Zhong and his wife were interested in finding a good family for Huang Wudie, this made Guo Yi, who had always secretly admired Huang Wudie, panic. He often got distracted even while studying, which resulted in Guo Jia being beaten a lot.
hand board.
Although the trivial things in life are trivial and complicated, if you calm down and have more patience to feel and taste them, they actually have a different flavor.
"Wave after wave... wave after wave..."
Lu Yan returned to General Hussar's Mansion humming a tune.
However, before he could enter the door of the mansion, two young men wearing the clothes of apprentice craftsmen who were about to become supervisors ran over in a hurry.
"Lu Xiuqi! Lu Xiuqi!"
"It worked! We succeeded!"
Lu Yan stopped and turned around to look at the two apprentices, and asked doubtfully: "What succeeded?"
"Red bricks!" one of the apprentices replied.
"And cement!!!" added another.
The two of them were like the two generals Heng Ha, talking non-stop.
It wasn't until the two of them talked that smoke started to rise from their throats that Lu Yan suddenly said: "Oh... I remember it!"
Last year, when Lu Yan was asked to supervise the construction of artillery, he mentioned red bricks and cement.
At that time, although Lao Geng and Ma Jun asked in detail about the production method and rough raw materials, Lu Yan's memory was not very clear, and what he said was vague. He only talked about the rough process and raw materials.
Lu Yan only remembered that the raw materials needed for cement are lime powder, clay and slag, and then these materials are kneaded, calcined, and mixed with water to become cement. This is also the simplest method of making cement.
With current equipment and technology, we can only produce the most primitive cement, which is at most comparable to Roman cement. It is simply a dream to achieve the quality and strength of cement in later generations. But for this era
Speaking of which, even the strength of Roman cement is completely sufficient.
Hearing that red bricks and cement had been successfully developed, Lu Yan felt dazed for a while. After all, with the emergence of cement and red bricks, future construction may undergo earth-shaking changes.
At this moment, Lu Yan felt that his infrastructure-mad soul had awakened!
After being in a trance and excited, Lu Yan quickly came to his senses and said to one of the apprentices: "You, go to the shipyard as quickly as possible to find Zhuge Liang and ask him to rush to the prison. Just tell him that it is urgent."
!”
The apprentice straightened his back, imitated the military sergeant and performed a nondescript military salute, and said: "Young man takes orders!"
"Da da da!"
As the first apprentice ran away, Lu Yan said to the other apprentice: "Go to the governor's house and notify Prefect Liu and ask him to go and serve as prisoner immediately!"
"You have an order!" The apprentice also gave a similar military salute, then turned around and ran towards the governor's mansion.
Lu Yan asked the servants in the palace to bring the white dragon horse and rushed as quickly as possible to take charge of the prison.
...
After leaving the city, Lu Yan galloped on his horse.
Soon, he came to the enlarged circle of Jiang Zuojian... town?
Arriving at the intersection of the town, Geng Liang and others had been waiting for a long time.
"I've seen Lu Qiaoqi!" Geng Liang led several officials who were about to serve as prisoners and saluted Lu Yan from a distance.
Lu Yan jumped off his horse, handed the reins to the young official who came up to him, and called out: "Old Geng!"
Geng Liang was getting fatter and fatter. Lu Yan looked at him and couldn't help but said: "You should eat less meat on weekdays. If you continue to be so fat, all kinds of diseases will come to you."
Geng Liang smiled and said in an indifferent tone: "We grew up hungry, and we couldn't eat meat even once a year... I still occasionally dream about the hard life in those early years.
I am not afraid of getting sick, but I am afraid that one day my good days will suddenly disappear.
So this meat can’t be stopped!”
Lu Yan's lips twitched and he didn't bother to persuade him anymore.
"Take me to see the red bricks and cement. If it is really the kind I want, all the craftsmen, handymen and officials involved in the development will be given a bonus of three months' salary!"
"Wow!!!"
"Wow! I'm getting rich!!"
"Thank you Lu Qiaoqi!"
Several officials around Geng Liang suddenly jumped and laughed with joy. It seemed that these people were officials who participated in the development of cement red bricks.
Geng Liang's face became solemn and he scolded: "How unbecoming it is to be so impudent in front of Lu Qiaoqi!"
After being scolded by Geng Liang, these officials immediately fell silent, but the glances they exchanged between each other still showed the unconcealable joy in their hearts.
Under the leadership of Geng Liang, Lu Yan arrived at the northwest location of the general prison center.
This place used to be a place for iron-making and forging farm tools and armor. Since the iron-making and forging departments were separated, it has been temporarily used as a place for the development of cement and red bricks.
Along the way, through Geng Liang's introduction, Lu Yan had a general understanding of the development of red bricks and cement.
Compared with cement, red bricks were refined quickly by craftsmen.
After all, red bricks, also called fire bricks, only need to be made of clay into adobe, and then briquettes and bricks are added to the kiln for firing. The process is roughly the same as firing green bricks.
"When the red bricks were first fired, the craftsmen tested them and found that the red bricks were actually slightly inferior to the green bricks in terms of strength and durability."
“But the firing process, consumption, cost, etc. of red bricks are much lower than those of green bricks.
Comprehensive comparison, red bricks that are simpler to produce and have higher yields can be used in more places in the future and will be used in a wider range."
Geng Liang told Lu Yan one by one the conclusions reached by his craftsmen.
Lu Yan nodded while listening: "Although the quality of red bricks is not as good as that of blue bricks, if it is combined with cement, it will be perfect."
Hearing the cement, Geng Liang couldn't help but exclaimed: "That cement is really a magical thing. I'm afraid only a relegated...genius like you can think of it!"
Lu Yan ignored Geng Liang's flattery and said, "Take me to see the cement first."
Geng Liang wiped the sweat from his face and said, "Here."

It took me a long time to fall asleep last night, but after calming down today, I understand that the country's choice is the wisest.
Although it is emotionally difficult to accept it, we should still return to rationality. Support the country and believe that they will not let us down.
