Three Kingdoms: Start by buying a governor.

My husband has an heir; this lineage continues.

They congratulated each other and shared their pregnancy experiences, filling the backyard with joy.

The news spread quickly.

Upon learning of this, Fang Xuanling, Du Ruhui, Xun Yu, and others came to offer their congratulations.

"Congratulations, Your Majesty! Congratulations, Your Majesty!"

"With an heir, the foundation of Youzhou is secure!"

Guo Jia chuckled and said, "Your Majesty, you've truly become a model of 'many children, many blessings'."

Xi Zhicai said, "Fengxiao, say less."

Guan Yu stroked his beard, his phoenix eyes full of smiles, and said, "It is a great matter that my elder brother has an heir. I will certainly do my utmost to assist my nephew."

Zhang Fei, with his loudest voice, exclaimed, "Brother! My nephew was born, and I, Old Zhang, will teach him martial arts!"

Zhao Yun, Dian Wei, Xu Chu, Cheng Yaojin, Qin Qiong... all the generals were also happy.

The entire Zhuoxian County was in an uproar.

The people cheered, "Have you heard? The wives of the Prince of Yan are all pregnant!"

"The King of Yan has an heir! Youzhou has a successor!"

"The King of Yan is benevolent and virtuous; he will surely bring blessings to his descendants!"

"They must be the young princes!"

"Perhaps there's even a young princess among them!"

The entire Zhuoxian County was as lively as during the Chinese New Year. Oh, it felt like the New Year had just ended, and it was like celebrating it all over again.

The entire Prince Yan's residence was in a flurry of activity.

Liu Ce ordered: Take good care of the ladies, and be meticulous in their diet and daily life.

He also bought many modern supplements from the system's online store to replenish the nutrition of his wives.

Cai Yan and the others were deeply moved.

"My husband, you've been so good to us..." Zou Yu wiped away her tears.

"Silly girl," Liu Ce hugged her, "you are my wife, and the child is my flesh and blood. If I don't treat you well, who else should I treat well?"

The wives enjoyed their husbands' love and care, and although the pregnancy symptoms were uncomfortable, they felt sweet inside.

...

A few days later, in the council hall of the Prince of Yan's residence.

Liu Ce summoned Song Yingxing and several chief craftsmen.

"Chang Geng, take a look at this." He handed over a roll of paper.

Song Yingxing took it, unfolded it, and read the detailed instructions on how to make "concrete": limestone is burned to make quicklime, clay is burned to make clinker, gypsum, sand, and gravel are added, mixed in proportion, and water is added and stirred...

In addition, there are instructions on how to use it: watering, vibrating, curing...

"This..." Song Yingxing's eyes lit up. "Your Majesty, if this object is completed, it will be as solid as stone, highly malleable, and a divine object for construction!"

"That's right," Liu Ce said with a smile. "Take it back and try it. Remember, keep the formula a secret and don't leak it."

"Yes!" Song Yingxing was overjoyed and hurriedly left with the craftsmen.

One week later, the experiment was a success.

Song Yingxing brought a grayish-white "stone" to see Liu Ce.

"Your Majesty, please look!" He threw the "stone" to the ground...

With a muffled thud, the stone didn't break, but it created a small crater in the ground.

Liu Ce picked it up, weighed it in his hand, and then tapped it with a hammer.

Hard and dense.

"Good!" he said with a smile. "Summon everyone for a meeting!"

Soon, the council chamber was filled with people.

Song Yingxing then brought over another concrete test block and placed it on the ground.

"Please look," he said, pointing to the sample block, "this substance is called 'concrete,' made from a mixture of lime, clay, sand, and other materials. Once dried, it is as hard as stone, impervious to water and fire, and resistant to insects. Moreover, it is highly malleable; whatever shape you want, you can shape it into during pouring."

He had someone strike the test block with a hammer, making a "bang, bang" sound, but the test block didn't budge.

Everyone stared in disbelief.

Fang Xuanling was the first to react: "Your Majesty! This material can be used to expand the city walls of Zhuoxian! The current city walls are made of rammed earth; if they are rebuilt with concrete, they will be as solid as a rock!"

Du Ruhui chimed in, "It can also be used for road construction! If the official roads between the counties of Youzhou were paved with concrete, the transportation efficiency would increase several times over!"

Xun Yu thought even further ahead, saying, "It can also be used for water conservancy projects! Building canals and dams, concrete is much more durable than mud and stone!"

Guo Jia chuckled wickedly, "They can even build prisons—prisoners locked up inside, trying to dig tunnels to escape? No way!"

Xi Zhicai added, "Building houses is also safer, as there is no fear of fire."

......

Liu Ce laughed and said, "You are all right. The uses of concrete are endless."

He stood up and began to make arrangements:

"First, the city wall of Zhuoxian was expanded with concrete, making it higher and thicker. Other counties and prefectures followed suit."

"Second, build roads. Centered on Zhuo County, construct concrete official roads to connect various counties and prefectures in Youzhou. In the future, we will also connect Bingzhou and Jizhou."

"Third, build reservoirs and canals for flood control and drought relief."

Fourth, build workshops and warehouses, and protect them from fire and moisture.

"Fifth...from now on, all houses will be built using concrete!"

The crowd was filled with excitement.

"Your Majesty, this is a great plan that benefits the country and its people!" Xun Yu exclaimed excitedly.

"We will certainly do our utmost to promote this!" Fang Xuanling and Du Ruhui said in unison.

Liu Ce nodded and said, "Good! Mr. Song will be in charge of this matter, with the Ministry of Works assisting. As many people as needed, allocate them; as many materials as needed, supply them. Money is not a problem; the Youzhou treasury has plenty."

"yes!"

After finishing his business, Liu Ce changed the subject, smiling as he looked at everyone:

"Oh, right, there's something else I need to do personally."

Everyone looked at him.

"You're all getting on in years," Liu Ce said, scanning the room. "It's time to get married and have children. Look at me, I've married ten wives, and now they're all going to be fathers. What about you? Still single? Hurry up! Our Youzhou needs a thriving population!"

He called out by name, "Fengxiao, you're nineteen, right? Zhicai, you're about the same. Zilong, Wenyuan... and Xuanling, Ruhui, Wenruo... you are all pillars of Youzhou. How can you settle down and build your careers if you don't start a family? Hurry up! Youzhou is stable now, it's the perfect time to start a family. Don't just focus on work, you need to take care of your personal matters too."

Guo Jia chuckled and said, "My lord, you're just happy yourself and can't stand seeing us single!"

"Nonsense!" Liu Ce laughed and scolded, "Hurry up, get all of them sorted out their personal lives this year! For the girls you fancy, I'll propose; for the ones you don't, I'll have someone introduce you. In short, speed things up!"

Everyone was both amused and exasperated, but their hearts were warmed.

Our lord truly treats them like family.

"We obey Your Majesty's command!" the crowd replied in unison.

The meeting ended, and everyone dispersed.

Liu Ce stood in the hall, thinking...

In short, everything is getting better.

As for those aristocratic families in Luoyang... well, whatever.
