Golden State, steel plant phase III project.

The heat in the huge factory building is unbearable. The tall steelmaking furnace is emitting infinite heat, and the blinding fire is constantly churning at the mouth of the furnace. Stone, who was in charge of explaining in front of the steel-making furnace with a rattan helmet, raised his hand and pointed to a rumbling pipe and said, "This is the ventilation pipe of the blower, and the cold air outside is blown in by a two-hundred-and-fifty-horsepower blower."

Here is the heat storage tank, where the cold air is preheated. Here, the room-temperature air is raised to a temperature of several hundred degrees Celsius and then poured into the smelter for induced combustion. ”

"Wait......." Huo Feng stood behind Stone and asked, "How did you warm up the cold air?" I was here the last time, and I only knew that your steelmaking method is very ingenious, but I didn't understand how your furnace works. ”

"The preheating of cold air is the hot exhaust gas after combustion." Stone looked back in surprise, "You were here before?" When have you been here? ”

The visiting procession consists of two traversers and two phoenixes. Binghuang looked curiously and wanted to touch everything, and Stone had to scold her many times, because many seemingly inconspicuous things in the steel mill were carried by high temperatures, which could easily cause death and injury. Although Huofeng is more stable, it can be seen that she is used to the world, and she is still very curious about seeing new things.

Stone's rhetorical question made Huofeng snort, she turned her head to look at Zhou Qingfeng, who looked lazy, and said angrily: "It's not because of him." In order to touch his hole cards, I have secretly come to Golden State a few times, and every time I come, I am surprised, and I don't understand too many places. Your steel mill is hot, so I'm naturally going to take a look. But the scale of what you're doing is so big, it's terrible. ”

Huo Feng looked at the huge factory building, and whispered: "Countless reincarnations, every time I admire, surprise or hate some heroes with strong combat power. You alone, with a few common people, have created a terrifying force far greater than any other powerful existence. This kind of ability makes people can't help but break their hearts. ”

After Huo Feng finished speaking, he glanced at Zhou Qingfeng with a complicated expression. It's just that Zhou Qingfeng still looks like a hanger, and he doesn't answer. Instead, Stone asked movingly, "Since you can come, have there been any other enemies?" ”

"I don't know, maybe I've been here, maybe I've never been. But don't worry too much, your handsome man can be called an invincible opponent in the world now, if anyone wants to make trouble, they have to weigh it. And as long as you don't kill a few of your leaders, what if you destroy this factory, you can still build it. "Huofeng sighed very much at the production capacity of the 'revolutionary army'.

Zhou Qingfeng finally interjected: "No matter how strong your personal strength is, it is limited, and even Huang Taiji now can't lift a few tons of iron." And our steam engines have long been able to do this. The beauty of industry is to make the impossible possible. So don't think too hard about the enemy. ”

Shi Dong nodded slightly, and said to Huo Feng again: "That Sister Wen of Zhou Qingfeng is studying a kind of defensive array, and in the future, our factory will be under the protection of the formation. When our defense system is built, unless there is a large-scale invasion by foreign enemies, we will not easily destroy our factories. ”

Huo Feng sighed, looked at Zhou Qingfeng again, and said, "When I first saw this kid, I guessed his origin. But we didn't expect you to be so powerful, and we didn't think that one day mortals would be able to fight against us desolate aliens. ”

Shi Stone glanced at Zhou Qingfeng, and continued to say to Huofeng: "I invited you here today to help us improve the steelmaking furnace with the help of your ability. I have mastered the process of adding limestone to remove phosphorus in molten iron, and designed a converter for this purpose to improve the efficiency of steelmaking by burning molten iron by air side blowing. But the problem is that I don't have a design, but I can't make it because of the materials. I need your help. ”

Stone talked to Huofeng about the details, and after talking for a long time, he said: "This plant is specially built for converters, and I have installed the gantry frame of the transfer furnace. As long as an air side blowing converter can be installed, our steel output will immediately increase tenfold, and the spring steel that Zhou Qingfeng wants can also be refined. But Zhao Ze's machinery factory just can't make this thing. ”

Huo Feng and Bing Huang carefully thought about it, turned back to Zhou Qingfeng and said, "Twenty years." ”

"What?" Zhou Qingfeng pretended to be stupid.

"If you want me to help with this, I want twenty years of life."

"You might as well kill me."

"If I cultivate with you, your longevity will also increase, and you will not suffer losses but still have to earn. A good thing that can increase your steel production tenfold, is it too much for me to ask you to live for 20 years? ”

Zhou Qingfeng was still ...... stunned, and Shi Stone preemptively said, "It's not too much." This thing has to be manufactured according to the normal process, and it will take decades to build it even if we know all the technical and technological details. I originally wanted to get a local method to get started, but if Huofeng can help, it will save us decades of time, which is very cost-effective. ”

Stone's eagerness annoyed Zhou Qingfeng, "Feelings don't want your life, right?" How can you speak for outsiders? ”

Stone immediately sneered, "Such a great beauty took the initiative to ask for double cultivation, and I am willing to spend fifty years of my life." Not to mention a big one with a small one, what a beautiful thing. It's just that you're hypocritical, how can you have so much to think about? ”

"My personal affairs are small, but I have a lot to do with the fate of the nation, so it's not too much to think about it carefully, right?"

"What's so cautious about this, the beauty promises to each other, it's not enough for you? For the sake of the rejuvenation of the country and the nation, can't you sacrifice yourself? ”

Seeing the two men arguing, Huo Feng immediately interrupted angrily: "You two are singing and harmonizing, what kind of trick are you playing in front of me?" Who said I was going to double train with this bastard? I want him to help me break the fate of reincarnation, it's just a combined cultivation, not a dual cultivation. Not the kind of thing you men think. ”

After speaking, the fire phoenix turned his head, turned around and left with the ice phoenix.

Shi Dong stepped on his feet to watch Huofeng leave, raised his leg and kicked Zhou Qingfeng, "What are you doing stunned?" Chase after it. Women are just to coax, brother, I can only help you so much. This girl has a request for you, and it is not difficult to chase it. If she runs away, you're too much of a scumbag. For my brother's sake, don't forget me about your 'ethnographic museum' project. ”

Brother Gaoyi, I said a lot of things that I am inconvenient to say!

A thousand words were all in plain sight, and Zhou Qingfeng gave up his hand and chased after Huofeng quickly. It's just that he just chased out of the factory, but he saw Huo Feng standing outside with a sneer, and he didn't run far at all.

"Uh, how did you ......." Zhou Qingfeng was separated by a distance of seven or eight meters, and thought, 'Why didn't this girl run away?' ’

"You know that you have to chase it out, you still have a little conscience." Huo Feng's cold face suddenly became charming, and he beckoned softly, "Don't let me come over yet." ”

This desolate xenomorph who has lived for thousands of generations is really not easy to bully. Zhou Qingfeng felt that he had seen through all the hole cards, so he could only walk over with his head down. He saw that Huofeng was still raising his hand, so he held it tentatively and gently. The moment the fingers touched, the bodies of the two were numb as if they were electrocuted, their skin and flesh trembled slightly, and most of the spiritual power between them was exchanged in an instant.

"Your spiritual power of the light system is really special, compatible with everything in the world." Huo Feng and Zhou Qingfeng held hands, and a small piece of iron ore appeared in the other hand. A white flame burned in the palm of his hand, which quickly liquefied the red light of the iron ore, and some of the slag fell naturally. She puffed out her mouth and blew at the red molten iron, and a hot wind stirred and ignited a strong flame.

When the carbon and oxygen in the molten iron are fully combusted, the carbon content in it drops significantly. Then Binghuang threw some slag and phosphorus removal lime into the molten iron, and after tossing and turning, a piece of fiery carbon steel appeared in front of Zhou Qingfeng. The temperature is slowly lowered for annealing, and then through the cold quenching of the ice phoenix and the tempering of the fire phoenix. The simplest carbon spring steel is complete.

Huofeng even molded this spring steel into the configuration of a flintlock gun spring, and then threw it to Zhou Qingfeng like a merit. Zhou Qingfeng could only nod at this, and said with a wry smile: "Okay, okay, I promise you." ”

originally expected Song Yingxing to make spring steel. But which guy is a master of miscellaneous science, and after making a bunch of machinery to improve the efficiency of engineering, he went to work on the measurement system, and wanted to compile a set of industrial standards for machinery and metallurgy for the 'revolutionary army'.

The reason for this is that the level of workers in the 'revolutionary army' is so poor that having clear standards can reduce all kinds of accidents and defective rates. This is the foundation of the foundation, and the importance is even more than spring steel. Zhou Qingfeng could only let him do it. It seems that this spring steel can only rely on the fire phoenix......

"Not only can I help you make steel, I can do a lot of things."

"I know."

"So, you're willing to double cultivate with me and Ice Phoenix?"

"Eh...... you just said that merging is not double cultivation?"

"Don't forget it."

"Oops...... that's not what I meant. Whatever you want, double cultivation is also good. I'd love to. ”

Binghuang pursed his lips and snickered on the side, and Zhou Qingfeng immediately stepped forward boldly to hug Huofeng's waist. But as soon as he stretched out his hand, Huo Feng immediately turned his face and opened it, and shouted angrily: "In broad daylight, you are not allowed to touch me." ”

"It's not good in broad daylight, but it's okay when the black light is blinding?" Zhou Qingfeng's eyes began to shine, he looked up at the sky, raised his hand to look at his watch, and said happily: "It's almost fast, it will be dark in a few hours." ”

Huofeng's face was red from the bastard's nonsense, she had seen countless heroes, some impassioned and some cheeky. But like Zhou Qingfeng, these gangs have a variety of characteristics and can be converted freely, which is really unique.

"You've got a blessed place, don't you?" Huo Feng asked again.

"Ah...... good idea, lady." Zhou Qingfeng was blessed to his heart, and immediately knew that Huofeng was talking about his own island of time and space. He hurriedly opened the space-time door and pulled the fire phoenix inward, "I forgot that I still have such a good place where it can get dark at any time. ”

Huofeng was embarrassed, desperately trying to break free from Zhou Qingfeng's pull, and shouted angrily: "You are really a scoundrel, who is your wife?" Who's going to talk to you when it's dark? I just wanted to tell you that your cave is not useful. You let it be the same as the outside world, but the time inside can be accelerated? ”

"What's good about speeding up? I don't want to grow old soon. ”

"I find that you seem to want to raise horses and breed, and if you give enough spiritual power in the blessed land of the cave, one day inside is worth a year outside. There are so many benefits. Now that the era of the flood has long passed, the blessed land of the cave that was created when the world was opened has long been extinguished, and your place should be the only one in the world. It is very good for spiritual practice. ”

"Oh...... lady knows so much, it's a baby."

"Don't talk nonsense, I didn't marry you."

"It doesn't matter, the sky should be a quilt, the ground should be a bed, and ....... into a cave room, ah! Don't tear my mouth. ”
