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

At noon in the Ordnance Supervision, everyone sat around and ate sheep.

Several children of Empress Changsun came to pay their respects at the Lizheng Hall. They heard that the little boy was eating sheep here, so they came together.

The Shangshi Bureau sent some more food boxes, and Du Ruhui simply asked officials from the Ministry of War to come over and eat together.

The fragrance overflowed, and Cheng Yaojin, who had finished his patrol, heard about it and came looking for it.

Yuan Yuan held steamed lamb chops in one hand and grilled lamb chops in the other, eating while talking to his colleagues.

There were many military generals in the Ministry of War, and several forbidden troops brought by Cheng Yaojin had a good time chatting with everyone.

Until King Zhao casually asked: "Then why don't you wear official uniform today?"

He was really curious. One of this kid's hobbies was to wear official uniforms like other officials.

What made her give up?

Yuan Yuan stopped eating meat. She tilted her head and thought for a moment, then suddenly opened her mouth into an "O" shape: "Hey, I forgot about it."

“Colleagues, let’s strike iron together soon!!!”

The surroundings were quiet for a moment, and the eunuch became anxious: "Little Master Yuan, the iron workshop is very dangerous!"

If nothing else, this little kid is not as tall as a hammer.

Yuan Yuan was a little worried. If he didn't make iron, how could he improve his iron-making skills?

She tilted her head, and King Zhao next to her consciously fed her a piece of fried chicken.

The little guy puffed up his chubby face and chewed, swallowed, and said loudly: "Then let my second brother forge iron!!!"

Everyone looked at Cheng Yaojin and thought to themselves that this man was already a first-class Duke, how could he come here to strike iron?

Unexpectedly, Cheng Yaojin laughed "haha" and said to the little boy: "Okay, okay, Aweng will give you a small sword to play with later."

The prince was a little curious and asked Yuan Yuan: "Why are you blacksmithing today?"

The weapons supervisor's workshop was only set up to develop weapons, and large-scale preparation was still done outside.

The scale of the equipment here is incomparable to that of Dafang outside.

The system reminded aloud: "Host, you can't tell him, change the topic quickly."

Yuan Yuan swallowed the mutton in his mouth and pointed to the sky: "Look over there!!!"

Everyone else looked up curiously, but saw nothing but two birds in the blue sky and white clouds.

Looking at the little boy again, he grabbed another piece of mutton chop and chewed it happily.

The prince patted her little head and said, "You little kid."

After eating the sheep, Princess Changle and Yuan Qing left, and the others followed the eunuch to the iron workshop with Cheng Yaojin.

There is an iron smelting furnace in the iron workshop. After thousands of years of development, the raw materials for weapons have also transformed from the earliest bronze to iron, and now they have evolved into steel.

The process of casting weapons is roughly hammering, planing and filing, quenching and polishing.

Finally, patterns, country names, serial numbers, etc. are engraved on the weapons.

The craftsman gave Cheng Yaojin a ready-made sword bar to beat, and he watched from the window.

Every time Cheng Yaojin hammered, sparks flew everywhere.

Yuan Yuan lay on King Zhao's back, covering her eyes with her little hands: "Cheng Aweng is really strong!"

Others were hammering with all their strength, but when Cheng Yaojin was hammering, the craftsman kept reminding him to hold back his strength.

Cheng Yaojin had already taken off his armor and was wearing a thin shirt. He was covered in sweat even after being beaten twice.

He laughed loudly while working: "Don't worry, I'll just break it and use it for myself."

The system has scanned all the equipment and equipment in the workshop into the system and formulated an improvement plan.

"Iron ore burns to produce pig iron with a carbon content of more than 2%, and stir-frying produces wrought iron with a carbon content of less than 0.05%. Iron with a carbon content of 0.05%-2% is steel."

"Steelmaking means fiddling with the carbon content in the iron."

“There is a lot of room for improvement in furnaces, blowers, fuels, solvents, and quenching materials.”

"Host, please learn ancient metallurgical technology in the near future. You will become prosperous after completing this task."

"Metallurgical technology can be used in many fields. Looking back, we will realize the freedom of time travel. System No. 002 is in the Qin Dynasty, System No. 003 is in the Ming Dynasty, System No. 004 is in the Han Dynasty, and System No. 005 is in the Song Dynasty... Let's grab energy points !”

If System 001 had eyes, it would be full of ambition at this time.

Yuan Yuan clenched her fists and punched King Zhao on the shoulder excitedly.

Go to the Qin Dynasty, go to the Qin Dynasty, go to the Qin Dynasty, see Brother Yingzheng, see Brother Wooden Brother, eat yokan, eat cakes and eat diced pork noodles! ! !

It seems that One Lord and One Unification has already planned the mission blueprint for the next ten years, and there is no room for anything else in its heart.

King Zhao grabbed the little boy's little fist and really didn't know what the child's excitement was about.

Du Ruhui also thought that the little master was just out of curiosity. He had always regretted not participating in the little guy's paper-making and car-making business, and wanted to watch the new invention from the front row.

Now I stopped thinking and took the people back to the Yamen of the Ministry of War.

Just after he left, Yuan Yuan also ended his fantasy about the territory of Da Qin's business.

She showed a sly smile and twitched her fingers at the prince and Li Tai beside her.

Prince Li Tai: ...This damn sense of fate.

The little boy jabbered and output, and everyone fell silent.

Prince: "You mean...improve the iron smelting process and equipment?"

This picture is too big! ! !

He would not dare to think about it even if he was given another 20 years of experience.

Li Tai also wanted to say it was impossible, but he thought of the papermaking technology before and held back his words.

Regardless of whether it succeeds or not, the little boy is full of enthusiasm and cannot extinguish it. At worst, it will waste some manpower and material resources.

The little guy has done a lot of work, what's wrong with doing some useless work?

Without ideas there is no progress.

Li Tai convinced himself and stopped talking.

Yuan Yuan patted King Zhao on the head, and King Zhao sighed slightly.

"Let's find some craftsmen to come and discuss it together."

The prince glanced at the little kid and thought to himself that the only ones who could accompany this kid in mischief were their good brothers and the future pillars of the Tang Dynasty.

"We might as well find a special place and build a workshop for future study."

The prince smiled and touched Yuan Yuan's head: "At that time, the imperial army will have to be dispatched to garrison. Many things must be approved by the saint."

Yuan Yuan blinked.

Cheng Yaojin was full of energy and punched him a few hundred times. He was about to give his little sworn brother a look that was three points proud, three points proud and four parts casual. When he turned his head and took a look, he was gone.

The Duke's face turned down and he was unhappy.

The audience is all gone, who are you still dancing for? ? ?

But I had already agreed to give the little boy a small sword, but I couldn't let it go.

He thought for a moment and waved to the guard at the door.

"Go and invite Duke Wu and General Qin to come over and say that there are urgent matters."

***

In Liangyi Hall, Li Shimin was reading the memorial sent from the north.

It has been more than two months since Li Ji and others went to the north to take over the Eastern Turks. The north is far more barren than imagined.

He stated in the memorial that if national conditions permitted, he hoped that the imperial court could send some capable people to help improve people's livelihood in the northern border.

At this time, people outside reported that the prince wanted to see him.

Li Shimin put down the memorial and let them in.

His Majesty the Emperor was originally a little worried and his face was very serious. When he heard the little boy's cry, he couldn't help but smile.

"Uncle Erlang, Uncle Erlang, the official Yuanyuan is here!!!"
