"Who is coming?" the soldiers on the front of the city shouted loudly.

"Yangdi Guo Jia." Guo Jia pushed the window and replied.

"What is the intention?"

“Trade for yourself.”

"Have a chance." Sure enough, everyone came without hesitation.

After the suspension bridge fell, the city gate opened. Gong Du then led the car into the city.

Tangxi City is more than one mile from a distance to a horizontal and vertical level, slightly longer from east to west and shorter from north to south. It is located in the Tangxi Pavilion in ten miles. In terms of systemic terms, it is a township. Tangxi City is located in the middle, and is several miles apart from the two cities of Yelu and Hebo, and craftsmen form their own settlements, which is the source of the people of the three cities. The three cities are mutually supportive, roughly in the shape of "Pin". Yelu City is simmering iron, Hebo City is mostly made of swords, and Tangxi City is mostly made of craftsmen's living.

As the car drove along the way, I saw countless smelting blast furnaces arranged along the banks of Tangxi River. Around Tangxi Lake, there were especially many iron smelting furnaces. The chimneys on the top of the furnace stood tall, swallowing clouds and fog. The smoke gathered at the top, connecting the long dragons. The clouds steeped in the clouds and clouds, and the water of Tangxi River was down, like fog and illusion, and the heat was simmering. The ice and snow on both sides melted, and the buds were early.

Apart from charcoal, charcoal and fish oil, it is also a regular fuel. A tuó yuè is also equipped with a tuó yuè next to the furnace to help the fire.

There are also many round kilns, widely distributed around the smelting site. The round kiln consists of four parts: kiln door, fire pool, kiln chamber, chimney, and four parts. The kiln is built in front of the furnace. In addition to burning tiles, bricks, blower ducts, etc., and building furnace materials, it also has baking sheets, iron heat treatment and pottery firing, and many other functions.

The blast furnace body is built with refractory bricks. The furnace foundation is made of clay, small pebbles, charcoal powder, ore powder, etc., and rammed earth plates, which are extremely strong. The "adding port" is located at the top of the furnace. The craftsman pours mixed materials such as ore and charcoal into the furnace cylinder and ignites and smels. The refined iron is flowed out from the "iron outlet" and injected into the mold in front of the furnace to form iron plates or iron anchors. Therefore, a "work shed" is also built in front of the furnace, which not only can shelter the wind and rain, prevent the iron from cooling or explosion when it flows out; it can also use the lever installed on the beam to add mixed materials to the top of the furnace, transport new cast iron anchors, and clean up the nodules in the furnace.

The blast furnace furnace cylinder is oval. It is divided into: furnace, forging furnace, steel stir-frying furnace, iron melting furnace, etc. At present, the advanced "heat exchange hot air furnace" has been used. The use of oval furnace and blowing facilities not only increases the volume of the furnace cylinder and is conducive to improving the iron smelting capacity; it can also shorten the distance between the air duct from the central area of ​​the blast furnace, thereby improving production efficiency. Similar to blast furnaces, it can produce one ton of cast iron per day.

By the way, the furnace cylinder from round to elliptical was a technological innovation in the history of iron smelting. It was not until more than a thousand years later that similar furnace bodies appeared in the West.

A glimpse of the whole leopard can tell the strength of the Han Dynasty and the unique skills of the world.

Nowadays, high-strength cast iron technology, which is known as "ductile iron" by later generations, has long been fully popularized. It is not difficult to decarbonize cast iron into steel. Quenching, cold forging, stir-frying steel... Famous craftsmen from all over the world have their own unique features.

In the era of cold weapons, two decisive skills: farming and iron smelting, both of which were unparalleled.

Get back to the point.

The city has streets and alleys, wineries and shops, and there are many houses. There is also a wide-reaching mansion. In the Han Dynasty, it was the "Iron Official Chief" official temple. In the Han Dynasty, iron officials were established in the iron production areas, iron officials were established, and iron officials were established, and drum castings were the main drum castings; in areas where iron officials were not produced, small iron officials were established to cast old iron. Now the Han Dynasty was eliminated. It is now the leader of the craftsman and the residence of Tangxi Dian.

The guards in the mansion had a solemn expression, all wearing iron armor. They had a tiger's back and a bear's waist, and their arms were particularly strong. They were all from iron-slayers.

Guo Jia also discovered that the inscriptions on the armor were different. There were Tangxi, Mo Yao, Hebo, Deng Shi, Wan Feng, Longyuan, Tai'a, Moye, and Gan Jiang, which were all in one place. Speaking of which, the nine famous swords, including Tangxi, Longyuan, Gan Jiang, and Moye, all came from this. In other words, within ten miles of Tangxi Pavilion, there were nine major casting sects. Each of them had the name of the sword furnace and the name of the sword furnace as the name of the sect.

As expected.

When Guo Jia and Gong Du entered the hall, they saw an old man sitting upright with a beard with gray hair and hair over a hundred and a half years old. Each had four people in the same row. Baotou Maoxu (headscarf) was embroidered with Mo Yao, Hebo, Deng Shi, Wan Feng, Long Yuan, Tai'a, Moye, Gan Jiang, and eight major sword-casting sects. The old man, the old man, came from Daitangxi, had no more or less, and had nine sects in total.

"Yangdi Guo Jia, pay a visit to Tangxi's 'old general'."

"Do you know me?" In this way, this person must be the former General of the Five-Secret General, and Tang Xidian is undoubtedly.

"I really don't know it." Guo Jiashi said, "I'm lucky to hear it when I came."

"Whoever said?" the old man asked again.

"My son."

"Who is your son?"

"Fufeng Song Qi, Song Yuanyi."

Hearing this, the old man was stunned. After a moment, he said, "I know it too. However, this person has long passed away and his whole family has been killed."

"It's hard to say anything," Guo Jia replied.

The General of the Five-Secret General Tang Xidian was Cao Teng of Dachang Qiu, and recommended it to the court. In the first year of Xiping, Song Qi married the Cao family and married the daughter of Cao Chi, the chief magistrate of Changshui, as his wife. Cao Chi's uncle was Cao Teng of Dachang Qiu. In other words, Tang Xidian must have close friends with the Song family and the Cao family. How could he not know the strong Hou Song Qi?

Guo Jia took Song Qi's jade pendant and presented it with him. Tang Xidian's expression, you can imagine: "It's really an old friend."

"The young master is in Shangcai. Because he knew all the secrets, he sent Guo Jia to report it."

"Why is it so urgent?"

"Someday ago, Nanyang defeated the army and entered Runan. He hid in the mountains of Kao, and soon he would attack this place to replenish weapons." Guo Jia replied.

Everyone sat on the seat with different expressions. Tang Xidian asked, "Where did Nanyang defeat the army?"

Tangxi craftsmen keep their doors behind closed doors and watch from the walls. It is also normal for them to keep the news closed.

Guo Jia then led Zhao Ci to attack and kill Qin Jie, the prefect of Nanyang, and told the story in a casual manner.

"This is actually happening." Everyone sat down and whispered to each other.

Seeing that it was difficult to make a conclusion, Guo Jia said again: "This is Jiangxia recruiting troops. He had previously followed the prefect Qin Jie to fight the Yellow Turban Rebellion. Most of the Hu cavalry could still escape under the iron hoof. His combat power was not the same as the bandits. I wonder if the old generals and all the weapons guarding the city were all ready."

"We are obsessed with making swords, but we do not understand the mechanisms." Tang Xidian shook his head: "The arches and crossbows in the store are more than enough to resist bandits. However, if we fight with elite soldiers of a hundred battles, we will not be able to match our strength."

Then the leader of the Hebo Sect stood up and said, "When the defeated army comes far away, you will abandon your armor and helmets. You have no weapons to attack the city, and you will shorten the food and grass. We will be strong and clear the land and guard the city and defend it. We should establish an invincible place."

"This is a bad word." Guo Jia said, "After the defeated army comes, there must be internal response. During the Yellow Turban chaos, I heard that many Nanyang craftsmen fled here. Among them, there must be a defeated army doing the work. If you open the city gate at night, everything will be over."

"Where is the collection book of craftsmen from Nanyang?" Tang Xidian asked.

"Reporting to the great craftsmen, there are thousands of craftsmen from Nanyang. It is difficult to distinguish for a while." Then the leader of the Deng army stood up and answered.

"It's all taken down." Chief Wanfeng said.

"No. If this happens, there will be riots. If you don't wait for the defeated army to attack the city, we will be killed in our own troubles." The leader of the Deng army waved his hands repeatedly.

The various factions in the hall, they all quarrel in a mess. They are nothing more than looking forward and looking forward.
