After Lu Yan and Zhuge Liang had a heart-to-heart talk, they completely tied Zhuge Liang to their own warship.

"As long as Kong Ming can grow up quickly, with his ability, I should be able to retire early, right?"

Lu Yan fantasized about the fairy days after he retired at the age of forty, hummed an unknown song and walked towards his mansion.

Huang Xu, Lu Xun, Chen Dao and others have already entered the Imperial Academy.

Guo Yi has also been studying hard under Guo Jia's "force" recently, preparing to be admitted to Tai Academy next year.

The lively cavalry general's mansion in the past lacked these most noisy guys, but now it seems a little deserted.

Huang Wudie has grown up and has become a graceful girl.

I heard that Huang Zhong and his wife were interested in finding a good family for Huang Wudie, which made Guo Yi, who had been secretly admiring Huang Wudie, so anxious that she was even distracted when studying, so she was hit by Guo Jia's hand.

Although the trivial matters in life are trivial and complicated, if you calm down and feel more patiently, it will actually be a different feeling.

"There is a wave in the wave...there is a wave in the wave..."

Lu Yan hummed a little tune and returned to the General's Mansion of the Cavalry.

However, before he could enter the mansion, two young people wearing apprenticeships of the craftsmen hurriedly ran over.

"Lu Piqi!Lu Piqi!"

"Success! We've succeeded!"

Lu Yan stopped and turned around to look at the two apprentices, and asked in confusion: "What did it succeed?"

"Red brick!" one of the apprentices replied.

"There is also cement!!!" another added.

The two of them were like the two generals of Hum and Ha, and they started talking nonstop.

It was not until the two of them were smoking in their throats that Lu Yan suddenly said, "Oh... I remember it!"

Last year, when Lu Yan proposed to build artillery by the supervisor, he brought up red bricks and cement.

Although Lao Geng and Ma Jun asked in detail about the production method and the general raw materials, Lu Yan's not remembered clearly and said vaguely, and only mentioned the general process and raw materials.

Lu Yan only remembered that the raw materials needed for cement were lime powder, clay and slag, and then these things were forged and burned, mixed with water and then turned into cement. This is also the easiest way to make cement.

With current equipment and technology, we can only make this 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. However, for this era, even the strength of Roman cement is completely enough.

When Lu Yan heard that the red bricks and cement were successfully developed, he was in a daze. 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 soul of the infrastructure madman was awakened!

After being in a trance and excitement, Lu Yan quickly came to his senses and said to one of the apprentices: "You, now you go to the shipyard to find Zhuge Liang as quickly as possible, and ask him to hurry up and serve as a supervisor, and he said he was in a hurry!"

The apprentice straightened his waist, and even imitated the soldiers in the army to perform an inappropriate military salute, saying, "The villain takes the order!"

"Da da da da!"

As the first apprentice ran away, Lu Yan said to another apprentice: "You go to the county magistrate's office to inform the prefect Liu and let him go to the general to be the supervisor immediately!"

"The villain is ordered!" The apprentice also gave a similar military salute, then turned around and ran towards the county magistrate's mansion.

Lu Yan asked the servants in the mansion to lead the white dragon horse and rushed to the supervisor as quickly as possible.

......

After leaving the city, Lu Yan ran wildly.

Soon, he came to the town that expanded another circle of people to serve as prison...?

When we arrived at the intersection of the town, Geng Liang and others had been waiting for a long time.

"I have seen Lu Piqiu!" Geng Liang led several officials who were in charge and saluted Lu Yan from afar.

After Lu Yan jumped off his war horse, handed the reins to the little official who came up, he called: "Old Geng!"

Geng Liang's body became more and more obese. Lu Yan looked at his appearance and couldn't help saying, "You should eat less meat on weekdays. If you become so fat, you will come to your door for all kinds of diseases."

Geng Liang smiled and said in an indifferent tone: "We grew up hungry since we were young, and we couldn't eat meat once a year... I occasionally dream about the hard life of the early years.

I am not afraid of being sick, but I am afraid that one day will suddenly disappear.

So this meat cannot be stopped!"

Lu Yan twitched his lips, and he was too lazy to persuade him again.

"Take me to see the red bricks and cement. If it is really the kind I want, all the craftsmen, peddlers and officials involved in the development will be paid for three months' salary bonus!"

"Wow!!!"

"Woo! Become rich!!"

"Thank you Lu Piaoqi!"

Several officials around Geng Liang immediately jumped and laughed ecstatically. It seemed that these people were all officials involved in the development of cement red bricks.

Geng Liang's face turned solemn and scolded: "How can it be so rude to be so arrogant in front of Lu Piqi!"

After being scolded by Geng Liang, these officials immediately became quiet, but their eyes and eyebrows that threw each other still showed the unconcealed joy in their hearts.

Under Geng Liang's leadership, Lu Yan came to the northwest of the center of the General Supervision Bureau.

This was used to be a place for iron smelting and forging agricultural tools and armor. Since the separation of the iron smelting and forging departments, it has been temporarily used as a development site for cement and red bricks.

Along the way, after Geng Liang's introduction, Lu Yan roughly learned about the development of red bricks and cement.

Compared to cement, the red bricks were quickly refined by craftsmen.

After all, red bricks, or fire bricks, only need to make adobe bricks from clay, and then use coal cakes and bricks to enter the kiln to fire. The process is roughly the same as firing blue bricks.

"When the red bricks were just successfully fired, after the craftsmen's test, they found that the red bricks were actually slightly inferior to the blue bricks in terms of strength and durability."

"But the firing process, consumption, cost, etc. of red bricks are much lower than those of blue bricks.

In summary, red bricks with simpler production and higher output will 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 drawn by his craftsmen.

Lu Yan nodded while listening: "Although the quality of red bricks is not as good as that of blue bricks, it would be perfect if cement is added."

Hearing the cement, Geng Liang couldn't help but exclaim: "That cement is really a magical thing. I'm afraid only a 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 replied, "Here."

I fell asleep for a long time last night, but after calming down today, I realized that the choice of the country is the wisest thing to do.

Although it is a bit difficult to accept emotionally, it should still return to rationality. Support the country and believe that they will not disappoint us.

come on!
