Crossing the rammed earth section of the goods, the red flag stepped on the green bricks.

The state gate opens due south.

Two huge stone lions, with flames in their mouths and gears, guarded the roadside.

On the side of the stone lion, Hong Fan saw the Wenzhongguan waiting here.

He now lives in the Wupin Shaojian Building, wearing a new cyan official uniform, stepping boots and wearing a crown, which is three points less gangsterly than when he was in Jinhai.

It is a great joy to meet in a foreign country.

The two happily crossed their arms, asked each other about the recent situation in the past month, and entered together after sending red flags.

Within the high walls, Hong Fan walked along the central axis, observing the well-defined buildings.

In the distance to his left, a huge column of gray-white smoke rose from behind the eaves of the building, connecting the sky.

The rumbling sound kept coming, but it was a little hollow because of the distance.

"At the west end of the city is a cement factory, and the output of the whole Dahua is this."

Wen Zhongjing explained, giving a thumbs up with his right hand.

"The factory occupies a wharf on its own, which is convenient for getting water, and it is also convenient for raw materials and goods to come and go."

"Cement?"

Hong Fan was stunned.

This is not a word to be expected.

"Is it the kind of volcanic mortar?"

He asked.

"You've seen a lot of it, and you know even the volcanic mortar?"

Smell the wonders.

"That thing is only available in Zhanzhou, it can resist water invasion and is used to build a dock fort to defend the water tribe."

"But we're not producing the original kind of goods here."

He spoke with self-sufficiency, and became more and more interested.

"The amount of volcanic ash is too small to be produced in large quantities, and the performance of the mortar produced is not good."

"The state ministry is different about cement."

"Special clay is mixed with limestone, then put in a kiln for high temperature incineration, and then ground into powder after cooling, and a certain amount of fine stone is added."

"The cement made in this way is extremely strong, and it is equipped with steel bones, and it takes a lot of effort to destroy the combat power of the Yuan Magnetic level!"

"From front to back, the cement recipe changed for seven or eight years. Zhuang Dajian finally relied on this merit to sit firmly in his position. ”

"Most of the cement produced now is supplied to Northern Xinjiang and Shenjing, and it is said that the giant spirit has been forced to give up trebuchet......

Hong Fan was amazed when he heard this.

Although it was easy to hear the middle view, he knew how many doorways there could be in these simple raw materials and processes.

The ratio of calcium silicate to calcium aluminate in clay, the temperature and time of heating, how to grind after cooling, the proportion of fine stone (gypsum) added......

And, most importantly, where to find a bonanza of several of the raw materials used above.

This is by no means something that the Traveler can come up with in mass production after a few afternoons of experimentation.

The two walked as they talked, turning into the building complex to the east.

This side is divided into courtyards of different sizes.

The sound of discussions, hammer strikes, and dragging heavy objects jumped and converged in the courtyard and fell on Hong Fan's ears.

"It's still early, so I'll show you where we're now."

Wen Zhongguan said as he stopped under the plaque that read "B Second Courtyard" and pushed the door open.

It's a big yard for all the way.

Hong Fan followed closely inside, feeling a darkness in front of him.

The first courtyard has an area of more than 300 square meters, surrounded by side rooms along one side wall and three sides.

The square tarp was tied to the eaves with ropes, presumably to keep out the rain.

Beneath the square cloth, there are two strange creations on display.

On the inside is a half-formed wooden frame, seven meters long from head to end, with long wooden strips joining a pair of butterfly-shaped frame wings, half of which has been covered with tanned leather.

On the outside, there are more than a dozen two-meter-square pieces of dark lacquered cloth and a miniature ellipsoid model made of bamboo strips.

"Qian Hong, Xiao Zhu, Xiao Jia, look who is here?!"

Wenzhongguan shouted loudly.

Suddenly, many people rushed out of the house, except for the three who had known each other in Jinhai for a long time, there were also seven or eight unfamiliar faces.

"But Hong Fan Gongzi of Jinhai City?"

Organic Spirits guessed cheerfully.

Wen Qian's new subordinates met for the first time.

But they have only been together for a month, and they have heard Hong Fan's name and deeds from their superiors many times.

"Sure enough, the second son has arrived!"

Zhu Jingfu wiped the black paint on his hands with his coat and came up to shake Hong Fan's hand.

Behind him, Jia Ziyong was wearing a thick leather skirt and holding a half-polished thin iron rod in his hand.

Hong Fan couldn't help laughing out loud and hugged the shoulders of the two.

When acquaintances meet, the huge courtyard is filled with joy.

"Hong Fan, look at the two guys in this courtyard!"

Qian Hong crossed his waist with one hand and pointed to the wooden frame and bamboo strips on the ground with the other.

"Do you know what Young Eunuch Wen and I are doing now?"

Hong Fan smiled when he heard this.

He knew it at first sight.

"You guys, this thing is trying to take away the creation of birds!"

Hearing this, the people in the courtyard were excited.

Qian Hong wanted to speak again, but was preempted by Hong Fan.

"You want to ask me this time, who do you think you two can get what they think?"

Qian Hong was stunned for a moment and nodded his head.

"If you want me to say, it can be done!"

Hong Fan replied.

Qian Hong is more serious, how can he be satisfied with this answer?

But the other party's next sentence of "different paths to the same end" finally made him die down.

After a few rounds of greetings, Wen Zhongguan led Hong Fan, who was a first-time visitor, to visit all sides, like a lion king showing off his new territory.

"I am now a young supervisor, and Qian Hong has been promoted to a master craftsman, and they are all independent projects."

"The second courtyard has an annual fund of 3,000 taels, I receive 2,000, and Qian Hong receives 1,000, which is much more abundant than when I was in Jinhai!"

A few people spoke, walking past a few wings on the west side.

In the corner of the first room was a blast furnace, and on the side was a set of blacksmith's tools.

Jia Ziyong was here just now, leading several sub-craftsmen to work.

His task is mundane and boring - to make iron nails.

It's technically simple, but the process is quite complex.

The fire is lit, the iron embryo is heated, forged into a thin stick, and hand-cut to a specified length.

This is the rough embryo of the iron nail.

Then the pier, knock the tip, polish, and finally quench, anneal and other heat treatment.

After so many steps, you can get a working iron nail.

[It turns out that before the advent of cutting machines and wire drawing machines, iron nails were made in this way......]

Hong Fan watched with relish, picked up a nail and looked at it carefully.

"This nail is so difficult to make, it has a bit of a luxury taste."

He remembered the "handmade customization" in his previous life and smiled.

"What do you mean, where are the nails not a luxury?"

Smell the wonders.

"Wealthier villagers often burn down their houses to recover nails from the ashes."

Jia Ziyong also interfaced.

"The second son grew up in the city since he was a child, but he didn't know that there were some remote places where nails could even be used for money!"

Hong Fan was dumbfounded when he heard this, as if he had an understanding.

In the second room, a lot of leather cloth is dried.

"My giant sky lantern was inspired by the prayer lantern."

Qian Hong introduced.

"The sky lantern should fly in the sky for a long time, and the most important thing is to be strong and light."

"I tried more than a dozen materials, and found that linen was the strongest, not only is it difficult to tear, but even a knife is not easy to cut."

"But the problem with linen was that the fibers were hollow and couldn't hold the heat, so I tried to apply different lacquers to the cloth......"
