At noon.

It was still snowing heavily.

After watching the forging process all morning, Zuo Tianxuan, who walked out of the forging building, felt dry eyes and flushed cheeks.

The environment in the forging room really made him feel uncomfortable.

When he walked outside, the wind was biting.

Taking out his mobile phone, Zuo Tianxuan clicked on the APP "Transportation Service".

The interface jumped to the taxi service column, which offered free taxi services.

After Zuo Tianxuan pressed the free taxi, a map of the area appeared on the screen.

"Didi, the driverless car is rushing to the area where you are located. The estimated arrival time of the vehicle is 2 minutes. Please wait where you are."

As the electronic broadcast sounded, Zuo Tianxuan hurried back to the room to get a coat and put it on, and then stood outside the house and began to wait for the vehicle to arrive. After

a long time, an unmanned vehicle drove at high speed from a distance and stopped not far in front of him.

After scanning the code to get on the car, the driverless car automatically set off to the located destination.

Xingcheng's unmanned driving technology now fully covers the entire city. It is a set of urban transportation systems jointly built by the science and technology department, the traffic management department and the Silver Moon Clan.

This system has been in operation for more than a hundred years. It has eliminated private cars and has become an important part of the operation system of Xingcheng.

With the assistance of this unmanned transportation system, there is no traffic jam in Xingcheng, and all road traffic lights and other facilities have been removed.

Charging vehicles is also very convenient. Wireless charging modules are installed underground in the city's roads.

Every road in the entire city is a charging station, which can replenish the energy consumption of unmanned vehicles in operation at any time.

The current model of Xingcheng is more like a pilot for the construction of Dawn City. In the future, this unmanned transportation system will also be moved to Dawn City.

The vehicle drove at high speed for about half an hour, gradually leaving the suburbs, and the number of towering buildings around it gradually increased. After

a long time, the unmanned vehicle stopped in front of a building.

There is a striking medical sign on this building. It is one of the medical stations serving the public in the western district of Xingcheng. There are also several security personnel fully armed on duty at the door.

Walking into the building, there is a crowd of people inside.

Zuo Tianxuan skillfully walked through the medical hall and came to the unmanned service station in the corner. There is a row of self-service medicine machines that can be operated by yourself.

After passing the identity authentication, he took the three boxes of medicine spit out by the robot and turned away.

Taking medicine regularly every month has become the norm in his life.

His disease is not serious, but it can never be eradicated.

The disease is called "hemp".

When the disease occurs, the eyes are bloodshot and red, the whole body is hot and itchy, and it feels like countless ants are crawling on the surface of the skin. This state will last for about half an hour before it fades.

This is also one of the reasons why he could not be admitted to the Battle Academy. It is difficult to meet the physical fitness level.

His grandfather and his father have similar illnesses. According to his grandfather, this is an ancestral disease in their family.

It is unknown which ancestor it came from.

What is certain is that the hemp disease should be caused by radiation from a special spiritual mine.

Their ancestors have been blacksmiths for generations, and it is normal to come into contact with different types of spiritual mines. Although these spiritual mines have been processed and the radiation intensity is far less than when they were just dug out, the radiation still exists.

One of his blacksmith ancestors was obviously irradiated by a special spiritual mine, which left a root of the disease in his body.

And this disease was also passed on to his descendants.

It is not completely impossible to eradicate this disease. His grandfather practiced the "Yansha Jue" to make his body have an affinity for fire attributes, and the problem of numbness has no effect on his grandfather.

But he can't.

The Yansha Jue is a relatively low-level technique among the existing techniques. This technique has not changed much for hundreds of years, and no technique research institute is willing to spend energy on improving this technique.

Therefore, the hidden dangers of the Yansha Jue in the early stage have never been solved.

Practicing will cause certain damage to the body, and it must be practiced after adulthood, otherwise it will cause irreversible damage to the growing body.

He is only 17 years old now, and it will take a few years to practice the Yansha Jue.

During this period, he can only take medicine to relieve the pain and torture caused by the genetic disease.

Fortunately, Xingcheng has included his ancestral disease in the free medical system. After all, although his family is now in a state of decline, they have also contributed a lot to the development of the front line, and they got this disease to forge weapons for the frontline soldiers.

After taking the medicine, Zuo Tianxuan did not stop and took a taxi back to the forging room.

At this time, in the forging room, grandpa had already cooked the dishes.

There were three dishes on the table, not many, two vegetarian and one meat, all of which were ordinary ingredients produced in the breeding farm inside Star City.

After lunch, Zuo Tianxuan sat by the window of the forging room with a tablet and began to look through the forging-related knowledge in the database.

As for whether to become a forger in the future, Zuo Tianxuan neither resisted nor rejected it.

His grades and physical fitness were not up to standard, and he could not be admitted to the ideal combat school. If he did not become a forger, there was no good place to go. He could only find a job with poor welfare and treatment. It would be better to follow his grandfather and become a forger.

Although the prospects of this industry are getting worse and worse, there are subsidies from Star City to receive after all.

No matter how bad it is, you will not starve to death.

He has been very familiar with forging since he was a child.

Modern weapons and equipment production takes the route of psychic weapons, which is a product that combines the two systems of technology and psychic energy. The specific forging process is divided into three steps.

The first step is software composition, which sets the size, shape, and other contents of the weapon in advance.

The second step is to input the parameters into the processing machine with psychic processing equipment.

The third step is that the machine processes and manufactures the weapons and equipment according to the parameters of the weapons and equipment and the spiritual materials invested.

This is a pipeline-style weapons and equipment manufacturing solution, which is characterized by extremely high efficiency and extremely low weapon scrap rate.

At this stage, Xingcheng also wants to improve the upper limit of spiritual energy weapon manufacturing and want to raise the strength of weapons manufactured in this mode to a higher level.

It is said that this technology originally came from Future City, but the relevant information is not accessible to him with his authority.

Their ancestral forging technology is different from the technology for forging psychic weapons, and uses the oldest smelting method.

To become a forger, the first step is to understand various types of spiritual ores.

For example, the properties, strength, melting point, and so on of spiritual ores.

Only by fully mastering the various characteristics of spiritual ores can we enter the next step of structural combination.

Integrating different spiritual ores is a skill that forgers must master.

Single spiritual ores generally have many shortcomings. Some spiritual ores have high strength but poor toughness, while some spiritual ores have high toughness and poor hardness.

The smelting process needs to combine the advantages of different spiritual ores to improve their practical value.

After the spiritual ore is smelted, the engraving of the spiritual nodes inside the weapon is done. This step requires the forger to have a very detailed understanding of the structure of the weapon and the structure of the spiritual array. Only when this step is done well can the weapon be considered completely formed.

The process of forging weapons by forgers requires thousands of hammers and tempers.

The early hammering was to refine the purity of the spiritual ore and use hammering to remove impurities inside the spiritual ore.

But in this era, the refining of spiritual ore does not need to be completed by hammering. After the spiritual ore is mined, the refining step will be completed in a specific processing factory.

The hammering of modern blacksmiths is actually the process of engraving.

Each hammering will change the internal structure of the spiritual ore. The spiritual node path is engraved in the spiritual ore using a specific method. When all the nodes are connected, a weapon has completed the last step of forging.

It is precisely because of the cumbersome forging process that the blacksmith industry has been gradually eliminated by the era of rapid development.

He can understand his grandfather's desire to revive the forging industry.

But he believes from the bottom of his heart that this industry has not kept up with the development of the times. The blacksmith industry cannot meet the growing demand for weapons and equipment on the front line.

When a person in charge of the executive department came to visit his grandfather at home, he heard what the executor said to his grandfather. Now he thinks it makes a lot of sense.

The executor said:

"If forgers continue to be the main output industry for weapons and equipment in Star City in the future, if you want to meet the needs of weapons and equipment on the front line, you need a large number of forgers. Have you ever thought about a problem? It costs money to train a large number of forgers. The weapons and equipment forged every year lead to additional consumption of resources, which is also a cost... With the blessing of various factors, it is inevitable that the forger industry will be eliminated by the times."

From the perspective of the senior management of Star City, Zuo Tianxuan felt that there was nothing wrong with these words.

Opening a major, training consumption, and manpower investment, which one does not burn resources.

The modern way of forging psychic weapons not only saves labor costs, but also reduces the material consumption during forging. It does not need to spend resources to train talents, and more importantly, the output efficiency is high.

It is obvious which one to choose between the two.

Although the senior management of Star City believes that Grandpa's idea is right and the human race cannot be without its own core technology, they still choose to develop with psychic weapons as the core, rather than Grandpa's outdated forging technology.

How to change the status quo, Zuo Tianxuan believes that there is no need to change at all.

The top leaders of Star City can see farther than them, and they know better which future development direction is more suitable for the human race.

Grandpa's persistence is more about not wanting to give up the ancestral craft. In fact, he has already compromised with the loneliness of the blacksmith lineage.

The development of the times is so ruthless.

Among the racial forces, the fittest will survive, and the weak will be eliminated.

It is the same when this perspective is applied to all walks of life in Star City. Only technologies that adapt to the development of the times can lead to the future. If those old industries are not innovative and cannot keep up with the pace of the times, they will be eliminated by the rapidly developing times.

It's like the front-line battle group model that was very popular back then.

Although he was not born in that era, he also learned about that period of time from history books.

At that time, there were many weak races on the front line. Star City opened up the front line using the battle group model. Through small-scale and convenient team operations, the surrounding forces were quickly cleared, and even wars were launched in multiple fields at the same time to maximize the efficiency of combat output.

The military guarded Star City and protected the rear.

Today, the human race rarely encounters weak races, and they are generally hostile forces that cannot be gnawed in a short period of time.

At this time, the front-line battle group mode naturally withdrew from the stage of history and was replaced by the current military external combat mode.

If an industry cannot adapt to the development of the times, it is normal to be eliminated by the new era.

The blacksmith is on the verge of being eliminated by the times.

In addition to working hard, his grandfather did not master the innovative technology that keeps up with the development of the times. Even if he was reluctant in his heart, he could do nothing in the face of the rolling tide of the times.

Zuo Tianxuan's current idea is very simple.

He became the last blacksmith to inherit the ancestral forging technology. As for his descendants, he would respect the choice of future generations and would not force them to inherit this ancestral craft.

He believed from the bottom of his heart that even if he was sent to Dawn City to move bricks, he would be a builder of the new era.

Their blacksmith industry is already a burden that cannot keep up with the development of the times.

It consumes more resources, but the output is far less than that of the assembly line processing plant, and it cannot be compared with the mass production of Destiny City.

Looking through the knowledge content related to forging, thinking about my thoughts, time passed quickly.

A few hours later, the grandfather's shout came from the direction of the forge. Zuo Tianxuan immediately put down the tablet in his hand, stood up and came to his grandfather, and continued to observe the process of his grandfather forging weapons.

Three months later.

Zuo Tianxuan began to forge for the first time.

Following his grandfather's posture, he took off his upper body clothes, stood in front of the hot forge, and picked up the heavy hammer.

The weight of the hammer reached more than 200 kilograms. Fortunately, the blood refining method he had practiced over the years was not in vain. He just felt a little strenuous.

In front of him was a piece of spiritual metal that was burned into golden red.

When the hammer slammed down, the red-hot metal did not deform, but only splashed a few golden red spots.

He did not stop, and swung the hammer again and smashed it down heavily. With the sound of metal clashing, Zuo Tianxuan began to beat the spiritual metal in accordance with the breathing rhythm taught by his grandfather, and shaped the spiritual metal in this way. As

time passed, sweat slid down his forehead and dripped onto the hot furnace plate, making a "sizzling" sound.

When the spiritual metal became a long strip, Zuo Tianxuan took a deep breath and began to operate the ancestral method "Casting God's Eye".

This method was jointly created by the early forgers and the Hupo Research Institute. After it was opened, Zuo Tianxuan's eyes turned black, and countless golden light groups appeared on the golden-red spiritual metal in his eyes, each of which had its fixed structure.

The next hammering was aimed at changing the structure of the spiritual metal.

With each hammering, the internal structure of the spiritual metal will change.

This process is like a puzzle, and each hammering is moving. Integrating the internal structure of the spiritual metal into a formation is the most important technology of the forger.

This time forging, he used the most basic solid formation.

This arrangement structure can greatly enhance the weapon's defense and is less likely to be destroyed by external forces.

As he hammered continuously, the sky gradually darkened.

When the spiritual structure inside the weapon was connected, Zuo Tianxuan used pliers to pick up the spiritual metal that had turned into a sword and put it into the purple coolant on the side.

As smoke rose, the surface of the purple liquid boiled, and it lasted for several seconds before returning to calm.

At this time, Zuo Tianxuan was sweating profusely, his face flushed, his right hand was sore from the shock, and his tiger's mouth was numb.

Taking the red long sword out of the cooling, Zuo Tianxuan grasped the cold hilt, his eyes swept from the tail of the sword to the tip of the sword, and then stretched out his left hand and flicked the sword body.

"Ding!"

A crisp sound of metal clashing sounded, and Zuo Tianxuan turned and looked at his grandfather standing behind him.

Grandpa smiled and nodded:

"Not bad, it sounds good. You are worthy of being my grandson, Zuo Duan. You are very talented in forging. Keep working hard!"
