The Three Kingdoms were fighting for supremacy, but I was busy with GDPThe Three Kingdoms were fight

In Jicheng, Gongsun Yue, under the order of his elder brother Gongsun Zan, led a thousand elite cavalrymen, opened the city gates, and broke out.

Although the Yellow Turbans wanted to stop them, they were all infantrymen and could not stop the cavalrymen at all.

They could only watch the thousand-man team go away, but there was nothing they could do.

The Yellow Turban commander knew that he could not wait any longer.

Ladders must be built as soon as possible to attack the city.

Those cavalrymen who broke out must have gone to ask for reinforcements.

If reinforcements really came first, the Yellow Turbans would definitely not be able to survive under the two-way attack.

More importantly, their food and grass could not be delayed any longer.

A quick battle must be decided.

The entire Yellow Turban camp was in a state of busyness.

Liu Yan stood on the city wall and looked down.

Youzhou was a turbulent place, and it was very bitter and cold.

The population was sparse and poor.

It was not a place to stay for a long time.

With his hands behind his back, he thought that he must choose a good place to go, and the right way is to get rid of this place as soon as possible.

…

Tiezhuang.

In the wilderness, Taishi Ci looked at the endless farmland and was very happy.

A full 60,000 acres!

After Liu Yu asked to cultivate 30,000 acres of reclaimed land, he temporarily added 30,000 newly reclaimed secondary fields.

Although it was very rough, according to the owner of the manor, it didn't need to be too good to grow sweet potatoes, as long as they could grow.

Although the time was short, everything went in an orderly manner.

Taishi Ci was looking forward to the harvest season.

The piles of grain would definitely make him drop his jaw to the ground.

Guan Yu and Zhang Fei were also very excited.

Being able to cultivate so much land means more harvest time.

A better tomorrow and life are waiting for them ahead.

"I miss Xingcai..." Zhang Fei looked at the wilderness. His life had improved, and he wanted to bring his wife and daughter back.

"Don't worry, I will definitely bring them back for you in a while." Liu Yu patted his shoulder.

"And mine." Guan Yu did not forget to cut in.

"Master of the manor!" Taishi Ci bowed and said, "My old mother is still in Qingzhou."

"Please allow me to return to Qingzhou and bring my mother over. We will leave tonight!"

"Ziyi, don't worry." Liu Yu said, "We will rush to Qingzhou for help in a short time."

"When the time comes, go directly to pick up your mother."

"Rush to Qingzhou?" Taishi Ci was confused.

Guan Yu and Zhang Fei were also confused. What was going on.

Why did they suddenly talk about going to Qingzhou?

"You will know after some time." Liu Yu had a meaningful smile on his face, and the three commanders thought he was unfathomable.

However, Liu Yu's past miracles made them believe that what the manor owner said must be true.

Let the three commanders gather the people and return to Tiezhuang. After that, Liu Yu took them to the steel mill.

"What kind of magical thing is this going to be?" Zhang Fei was looking forward to it.

Liu Yu ordered people to find a lot of stones, crush them and grind them into powder, and put them separately.

The three commanders were confused.

I don't know what to do.

"You will know when it's done." Liu Yu chuckled and told several craftsmen who were making blast furnaces to get busy.

After mixing several ingredients according to the proportions in his mind, he told the craftsmen to use specially made containers for calcination.

What he wanted to make was glass.

With experienced calciners, many high-temperature operations can be achieved.

However, although glass can be made, it can only be tried on a small scale.

Large-scale production is still unrealistic.

Glass, which belongs to the silicate direction like cement, also has the process of crushing and grinding raw materials.

In this year, small-scale production is OK, but there is no production equipment for large-scale grinding.

Several craftsmen were busy, heating up and controlling the temperature.

The powder gradually melted, and bubbles came out, breaking the sticky surface.

The three commanders were amazed.

"Oh, it turns out that after the stone melts, it is also like molten iron, red!" Zhang Fei stared at the special tool with wide eyes, very surprised.

Guan Yu and Taishi Ci were silent, but the glittering light in their eyes set off the excitement in their hearts.

"It's almost melted, pour it into the mold." Liu Yu, who compared the experience of glass manufacturing in his mind system, ordered the craftsmen.

Several craftsmen carefully poured the hot and viscous liquid into the mold.

In several hemispherical molds, the red liquid gradually cooled down.

"It's actually Liuli!" Taishi Ci raised his voice, expressing his disbelief to the fullest.

Guan Yu frowned, and the red that was gradually cooling downThe liquid became more and more transparent.

Zhang Fei's mouth twitched, and he muttered to himself: "Oh my God!"

"The owner of the manor can even make the legendary colored glaze."

"Moreover, it's just a few stones. After breaking them, they can be burned casually to make such precious colored glaze."

"Am I dreaming?" He rubbed his eyes hard.

Nothing in front of him changed, which made him deeply know that the scene was real.

"This is not a casual burning." Guan Yu shook his head and said seriously.

"Whether it is the choice of the stones, the weight, or the control of the temperature, it is not something that ordinary people can think of."

"Even if you know that these stones can be made into colored glaze, just how much of each kind to put in will stump countless people."

"That's true." Taishi Ci nodded in agreement.

"Finally it's done!" Zhang Fei saw the transparent colored glaze and couldn't wait to rush up and want to play with it in his hands.

"Stop!" Liu Yu called out to Zhang Fei, who was quick to stop.

"Don't think it's not red now, but it's still several hundred degrees."

"Wait until it's annealed and the temperature drops to room temperature before you can play with it."

"Thanks to the reminder from the owner of the manor." Zhang Fei quickly retracted his outstretched hand.

"I, Zhang, will never be so reckless again."

"However, how hot are those several hundred degrees?"

Guan Yu and Taishi Ci were also very curious.

"I'll explain it to you when I have time." Liu Yu interrupted the doubts of several people and continued to work with the craftsmen.

After annealing, the colored glaze became a solid hemisphere.

He held the glass hemisphere at room temperature in his hand to observe.

"The quality is very poor, just use it."

The three commanders looked at each other.

The owner of the manor even said that the precious colored glaze was just okay. Is there any treasure in the world that the owner of the manor would like?

Liu Yu threw one to each of the three commanders and asked them to play with it.

Then he told the craftsmen to keep busy.

Add different metal ores to the raw materials to make colored glass.

Also made in the shape of a hemisphere.

The three commanders held several colors of colored glass and played with them carefully, and they were reluctant to put them down.

Putting the green colored glass hemisphere in front of his eyes and looking at it in the sun, Zhang Fei sighed: "I think I'm getting tens of millions of dollars now."

"This thing looks extremely precious!"

"But what is it used for?"

"To decorate weapons." Liu Yu, who was busy with the craftsmen, said without looking back.
