The machine did not stop, and before you knew it, more than an hour had passed, and the first smelting furnace had begun to be red-hot, and the iron concentrate had melted and reacted with the bamboo charcoal.

It was only at this time that the Zhang family began to put in the spirit stone powder and began to stir.

Then, the Zhang family began the most critical operation. Four fans began to inject air into the molten iron, and the agitation continued.

In a few moments, gray-brown smoke began to appear above the molten iron, and the smoke seemed to be heavy, but it was quickly carried away by the spell of the wind.

However, the Zhang family's technology has made a lot of progress, and these gray-brown smoke did not fly away, but entered the pool, and a large amount of gray-brown smoke precipitated in the water, and gradually appeared black-brown.

This continued for more than half an hour, until no gray-brown smoke was generated, and the furnace again moved down the truss, and then two more fans continued to blow air into it. At this time, the air contained a thick aura, and it lasted for more than half an hour, and there was gradually a treasure light circulating above the molten iron.

A worker shouted, "Pour!"

The fan was removed, the smelting furnace was operated by means of pulleys and iron cables, and the molten iron that emitted a precious light was injected into the mold.

After more than an hour of cooling, pieces of boxy, half-meter-square black iron ingots appeared.

At this time, the iron ingot was still in a dark red red state, but Li Yousheng and the others couldn't take care of it, so they went up to identify it.

After a few moments, everyone's eyes widened: 95% purity!

Without any forging, it is 95% dark iron!

"No wonder the Zhang family wants us to swear to occupy 80% of the shares!" Li Yousheng sighed.

Feng Tai thought for a while and held back a sentence: "Before, we were all deceived!"

Li Yousheng smiled: "It's not a lie, it can only be said that the Zhang family provides the first half of the technology, and it can also directly produce 60% of the dark iron." It's just that it obviously can't compare to the current technology of the Zhang family.

Xuantie Factory, we made the right bet!"

Feng Tai nodded, yes, the bet was right! When he chose the Zhang family and the Xuantie Factory, it was a bet. And now, it seems, he made the right bet. Such a Xuantie factory directly threw the Xuantie Guild out of several streets.

But their surprise was just the beginning.

However, as the production line gradually operates, an average of one furnace is poured in an hour. A furnace of molten iron is three tons of black iron, 95% purity.

The production line, like a monster, devoured a huge amount of ore, spirit stone, bamboo charcoal, and even the water that drives the steam turbine, but produced pieces of exquisite black iron ingots.

Whether it is high-quality ore or low-quality ore, the production line is not refusal!

Suddenly, there was an alternative sound of machinery spinning nearby, and when I turned my head, I saw that the workers had started the 'machine tool'.

Li Yousheng and the others widened their eyes, and they saw a furnace of molten iron sliding down a new truss into a new factory area and starting pouring again.

This time, the molten iron was poured into a high-temperature container, the container was sealed, and the molten iron began to flow out slowly and draw wire under the container, and the molten iron began to cool down and a wire appeared in the process of flowing out.

Immediately a worker pulled out the wire and wrapped it around a machine. The machine begins to rotate slowly, and the molten iron flows out under the action of gravity, enters the pool and is quenched, and finally rolled into a thin silk thread.

Then the molten iron entered another container, and under the control of the workers, the container began to be cast into some precision molds, and after cooling and quenching, one by one, helmets, cuirasses, shoulder pads, etc. appeared.

These items were carefully placed into the machine tool by the workers, and the machine was seen to fall with a bang, but when they heard a sonorous sound, they saw that some lines appeared on the parts of the armor.

Then take it out and give it to the next machine. After the next machine adjusts its position, the upper part of the texture is stamped again. Then, switch to the next machine......

A dozen times later, within a few minutes, a helmet covered with exquisite and precise formations appeared.

Some machine tools are responsible for helmets, some are responsible for cuirass, some are responsible for back armor, some are responsible for shoulder pads, and so on.

Li Yousheng and others saw that these machine tools were like stamps, and they 'printed' a set of magic weapon embryos with a few clicks.

"Goo Dong......" Li Yousheng swallowed a mouthful of saliva, and he suddenly realized that he had lived in vain in the past.

Perhaps these machines do not have the dexterity of cultivators, nor the subtlety of magic weapons, but it is these seemingly bulky machines that are producing semi-finished magic weapon embryos at an unprecedented speed.

The roar of the machine, the power of industry is revealed little by little, and it is also changing the thinking of Li Yousheng and others little by little. The current production method completely subverts their imagination.

It wasn't until the sun rose that everyone slowly woke up from this surprise.

A new era seems to be raising its head little by little.

Zhang Shengye came to everyone's side and said softly: "How is it, do you still have any questions about the Zhang family's 80% share?"

Li Yousheng opened his mouth, and finally sighed with emotion: "Amazing, no wonder the Zhang family has such a huge production capacity, no wonder it must be a magnetic mountain." ”

Zhang Shengye smiled proudly: "The Zhang family is not enough, everyone from their own homes to choose clever people to come and learn, and when everyone is familiar with our production process and technology, we will expand the new plant."

Hopefully, in two months, everything will be on track. Our goal is Nissan Darkiron ...... 10,000 tons!"

"Ah......" Many people were frightened by Zhang Shengye's tone.

Zhang Shengye walked out with his hands behind his back and his head held high: "It's just 10,000 tons, is it too much?"

It wasn't until Zhang Shengye left that everyone looked at each other and saw the shock in their eyes.

With the current production line, it can produce about 3 tons in an hour, and a production line is 120 tons a day......

At this moment, Zhang Hao spoke again, but not to Li Yousheng and others, but to the workers of the Zhang family: "Okay, the demonstration is over." You can adjust the production line and strive to double the production efficiency. ”

"Yes. ”

Li Yousheng grabbed Zhang Hao in surprise: "Virtuous nephew, can this production efficiency be doubled?"

"Yes. The main thing is that raw materials can't keep up. The speed of mining, spirit stones, charcoal, etc., all restrict production efficiency. If these can be addressed, doubling production efficiency will not be a problem.

Also, because of the demonstration just now, the production line has done a lot of division of labor, which virtually reduces efficiency. When the scale is expanded in the future, each production line only does one thing, and the efficiency may be improved a lot. ”

After speaking, Zhang Hao left. Because Zhang Hao has more important things to do, that is...... Go home and cook steel!

Although Zhang Hao has the title of vice president, the Xuantie factory is finally on the right track, and Zhang Hao begins to care about his own situation. In particular, the war in the east is becoming more and more unfavorable, which makes Zhang Hao have a sense of urgency.

It was the eastern trade routes that were almost cut off, and the price of western pills was rising. The whole West is brewing this unease. I am afraid that there is not much time left for the Zhang family.

The plan of the Great Voyage must be accelerated.

It's just that Zhang Hao doesn't know for the time being, and the current country of Qixia is already a mess.

Ouyang Si had just returned to the imperial capital when he was stunned by the chaos in the imperial capital.

At this time, the country of Jinyang also came with a messenger, bringing shocking news!
