All the members are in love with the group, and the cub is causing trouble in the Tang Dynasty.

The list of reduced palace maids had already been decided. Once Li Yuan agreed, Queen Changsun summoned everyone to the open space in front of Taiji Hall that night.

The sky was dark, but the surrounding firelight swayed with the evening breeze.

The emperor and empress stood on the high platform, and the maids who were about to leave the palace bowed and said goodbye.

The maids wearing uniform palace uniforms were kneeling in rows. Because there were so many people, it was impossible to tell their age or remember their appearance. Their attitude was unanimously respectful.

Li Shimin asked: "Those among you, fathers and brothers who died in battle with me, stand up."

The maid below stood up for the most part.

Li Shimin felt very heavy.

"Please accept my respects from Li Shimin."

He bowed solemnly, and Queen Changsun also bent down.

Many of the maids below were moved and cried.

Li Shimin: "I hereby promise that you and your children will never experience war or a life of displacement again."

The cries of the palace maids continued for a long time.

***

Entering Yuanfang, Dingbei Wangfu.

Yuan Yuan studied ancient Chinese iron smelting skills in the system for a while, and when he came out, he was already seeing stars.

She hugged her father and hummed and coquettishly said: "Dad, Daddy, studying is really hard!!!"

Thinking of the delicacies she had eaten at Risemaden during the day, Madoka showed a nostalgic look on her face: "It would be great if I could eat sizzling fish every day..."

The old father touched her little head: "You are still young, you can start learning again in a few years."

Yuan Yuan sat up, smiled "hehe" and fell into his father's arms.

"Dad, can we stay in Tang Dynasty forever?"

Yuan Meng put a quilt on her: "No. Your body is still in the nutrition warehouse. After this time and space disappears, your consciousness will be forcibly sent back to the interstellar."

Yuan Yuan pouted, turned over, and said anxiously: "Then what should everyone do if I can't bear to leave???"

The old father sighed slightly: "You can stay here until... no one around you is gone."

The little kid tilted his head and thought, "Why aren't you here?"

The best dad in the universe said nothing.

The life span of the ancient Blue Star people is already short, and the life span of the ancient people is even shorter.

The old father feels a little distressed. As the little guy grows up, he has to face the departure of people close to him again and again.

Before I could say a few more words, the big-hearted little kid had already fallen asleep.

Yuan Yuan's consciousness entered systematic learning again. This time, he was learning the basic knowledge of ancient architecture.

Earn salary during the day and save energy points at night.

The cub has sacrificed so much for world peace! ! !

In her current systematic courses, except for classics and history, which require listening to allusions and memorizing texts, almost all other professional courses are virtual practical classes.

Let the teacher lead her to select virtual raw materials in order and freely mix them. The system will determine whether the finished product is qualified and which solution is the best.

Do it yourself, remembering the names and functions of the materials during the process. When you are finished, you will understand the process and principles.

The raw materials needed for making cement in ancient China included limestone, clay and iron ore. These materials have been excavated in this dynasty.

石灰石占比67-75%，粘土占比10-15%，铁矿占比0.5-1.5%，煤占比8.5-11%。

Grind limestone and clay into flour, calcine until partially or completely melted, and finally add iron powder or iron slag and grind together to obtain cement.

In the middle of the night, He Fan felt energy fluctuations in the room and opened his eyes.

In front of him are two cement formulas and production processes submitted by the system, including the lowest-cost qualified product and the slightly higher-cost best product.

There is also a design drawing of a metallurgical blast furnace. The blast furnace is designed to be like a large waisted drum, with thin ends at both ends and a thick middle. This can make the distribution of gas even, fully contact the charge and gas, save fuel, and extend the life of the furnace wall.

He Fan fell into deep thought. Although these things were very simple and backward, they could not be easily found in interstellar history books.

But for a three-and-a-half-year-old kid, with such a high R&D efficiency, will he be criticized?

He sat up and worked conscientiously as a drawing tool man.

The next day, Yuan Yuan did not have to go on duty at the weapons inspection, so he slept until he woke up naturally.

Naturally, the old father had gone to the military camp to be an emotionless devil coach. As soon as Yuan Yuan opened his eyes, he saw a stack of paper placed on the bedside.

The little kid happily pulled out his new "SpongeBob SquarePants" schoolbag and stuffed all the papers into it.

Mrs. Ye took her little granddaughter to finish breakfast and went to Tai Chi Palace with her.

Now that the little baby is familiar with the palace, there is no need for anyone to take her into the palace. Madam Ye sent her outside Chengtian Gate, and she jumped in and ran inside.

Mrs. Ye stepped aside and handed the two baskets of beggar's chickens to the guard sergeant who had just been replaced on duty. She told him that the milk tea ordered would not be delivered until the afternoon.

The sergeant was very discerning, thanked him, agreed on a time to collect the milk tea, and immediately ran to the guard post carrying two large baskets.

Any delay would be disrespectful to beggar's chicken and fried chicken! ! !

When Yuan Yuan entered Hongwen Hall, it was the break between two classes.

She was wearing a bright yellow skirt, a bright yellow hairpin, and carrying a bright yellow schoolbag. She jumped into the school and ran into the school. Not to mention how cute she was.

He was immediately surrounded by several brothers.

Yuan Yuan happily spun around in circles: "The bag was given to me by my sister, and the clothes were all made by my aunt!!!"

So proud.

Li Tai was very envious: "If you sell this bag and these clothes in a clothing store, you can make a fortune every day."

Yuan Yuan was extremely proud: "My second uncle is going to open a clothing store soon!!!"

The eldest grandson poked her breasts: "Oh, Yuan Bao'er will soon be the young boss of the tailor shop. I'm disrespectful."

Yuan Yuan smiled and narrowed her eyes, covering her chubby face in intoxication, then took out the stack of paper from her schoolbag and placed it on Li Tai's table.

The others didn't know why, and King Zhao beside the little boy stretched out his hand to take it and look at it.

He read it quickly and then handed it to the prince: "In this way, we will have greater leverage in the negotiations with the six ministers this afternoon."

Several other people gathered around curiously.

“What is what???”

"Cement...is such a good thing, so it can be used to build roads, city walls, and houses!"

"This blast furnace is not like a furnace in an ironworks. No wonder the kid was serious about improving iron smelting before..."

The prince looked complicated and asked the little guy: "Did King Dongping teach you this again?"

Yuan Yuan reacted for a while and realized that King Dongping was the annoying uncle. He nodded his head and said, "Yeah, yeah, Uncle He Fan taught me this!!!"

"I can make cement and make iron now!!!"

The little kid slowly pulled out the purse containing Qiuqiu candy from his bag and stuffed one into his mouth.

King Zhao and the prince looked at each other and said, "Let's make the cement today, and let's move the negotiation to tomorrow before the next shift."

According to the time on the cement list, most of the work should be done tomorrow evening, and the effect can be seen.

The prince nodded: "Uncle Six will go to the Ministry of Industry to prepare first. I will go see Aye and inform him of the matter."

Both of them were about to walk out, but they grabbed Yuan Xiaopang'er's hand by chance.

Prince: "Uncle Six, I'm going to see Aye. I can't do it without Yuan Baoer."

If Aye is in a bad mood, he has to bring a little shield! ! !

King Zhao did not give in: "The Minister of the Ministry of Industry had objections to our construction of the workshop..."

He has to bring a little nemesis with middle-aged and elderly officials to be more secure.

The two men's eyes fought for [-] rounds in mid-air, and then Academician Yu walked into the school.
