"It's a bit difficult to build this thing, but if you try it, you should be able to build it......" Qian Su's gaze swept over the single-cylinder steam engine inch by inch, and said very professionally, " The most difficult thing to make this thing is this cylinder and these connected crankshafts and parts, these things, just rely on the blacksmith to knock and beat, you must open the mold, directly use the method of cast iron, once cast and molding, and then polish, the manufacturing bureau has already had a cast iron workshop before, if you want to make this thing, just open a furnace in the cast iron workshop, and prepare some tools......"

"Yes, yes, I also think so, several key parts of this water and fire machine, must be opened, cast and polished, but the accuracy needs to be relatively high, need to be particularly careful, especially the cylinder and the back and forth of the round iron, some exquisite, make big, can't stuff in, make small, easy to leak, this round iron and crankshaft connecting rod these things can not be made of cast iron, need to be made of steel, some other workpieces, can be made of brass!" As a blacksmith, Yan Dechang looked at the never-before-seen water and fire machine in front of him, and he was also a little moved, "In our blacksmith workshop, as long as it is transformed, it should be able to be built!"

"Dad, you want to make this steamed ...... Water...... The fire engine, you can take Brother Tiezhu to the manufacturing bureau and build it with Uncle Qian, the manufacturing bureau is spacious, and the cast iron workshop is also ready-made, which is also convenient!"

Qian Su and Yan Dechang glanced at each other, the two of them nodded, and Yan Dechang spoke, "This...... Yes, I'll discuss it with your Uncle Qian!"

"I feel that this thing should be useful, but for a while, I haven't figured out what I can do?" Qian Su scratched his head.

"Hahaha, if this thing wants to play a role, in fact, it would be good to create a little supporting thing, threshing, rice milling, oil extraction, sawing wood, these are all fine, after making this thing, we can first get a mill and sawmill in Liuhe Town, then there is no need for livestock in the mill, we will use this water and fire machine to drive the grinding disc, and the sawmill is the same......" Yan Liqiang said lightly.

"It's also convenient to drive the grinding disc, the simplest way to get a belt or a runner can be, but how to see wood with this thing, the saw is not easy to drive!" Yan Dechang asked suspiciously.

"It's as simple as sawing wood, of course ordinary saws can't, just make the saw blade of sawed wood into a round!" Yan Liqiang casually said an "invention" "In the future, this water and fire machine will be built on the side of the manufacturing bureau, and the blacksmith workshop in Liuhe Town can make something that matches the parallel cargo machine, such as a round saw blade or something......"

"Ah, the round saw blade, the round saw blade, why didn't I think of it......" Yan Dechang slapped his head heavily.

Not only Yan Dechang, but even the disciples of the Lingshan Sect's Qianji Hall also widened their eyes when they heard the circular saw blade that Yan Liqiang said casually......

"This water and fire machine is very useful, in addition to these uses, such as connecting it with the water wheel, it can pump water, and it can actually be used in the blacksmith workshop, if you can use this thing to strike iron, you can save a lot of manpower, fast and good!"

Yan Liqiang's words suddenly opened the minds of the people around him, and made the surrounding craftsmen excited all of a sudden, and began to discuss warmly what this water and fire machine can be used for, in the final analysis, this thing is indeed convenient, as long as the boiler is burned after adding water, it can keep moving, it is larger than human and animal power, and it can last, it can definitely come in handy, and the boiler is not picky, and it can be used to burn firewood and coal......

......

From day to night, the courtyard of the Yan family's blacksmith workshop was crowded, and countless people came to see the excitement.

However, the water and fire machine was also placed in the Yan family's blacksmith workshop for a day, and the next day, Yan Liqiang took this water and fire machine and Yan Dechang, Zhou Tiezhu, as well as Wen Zhaolun and a cadre from the Lingshan faction to the Huanglong County Manufacturing Bureau.

In the Huanglong County Manufacturing Bureau, as soon as the steam engine was put down, Yan Liqiang took Wen Zhaolun and a cadre of disciples of the Lingshan faction to visit the four-wheeled carriage production line, even if Wen Zhaolun and the disciples of Qianjitang boasted that they were well-informed, but the four-wheeled carriage production line that had begun to take shape in the manufacturing bureau still suppressed them.

However, Wen Zhaolun and the others did not stay in Huanglong County for many days, after sending the steam engine to Yan Liqiang's hands and helping Yan Liqiang to use the prestige of the Lingshan faction to subdue the threat of the Feitianmen, Wen Zhaolun and the disciples of the Lingshan faction completed the task, and then left Huanglong County, and returned to the Lingshan faction with the six four-wheeled carriages that Yan Liqiang gave to the Lingshan faction and a handwritten letter to Zhang Yourong.

In the letter to Zhang Yourong, Yan Liqiang first thanked Zhang Yourong and the Lingshan faction for sending charcoal in the snow, and then discussed the role of gears with Zhang Yourong, and finally talked about the application prospects of the water and fire machine, and gave a very high evaluation of Zhang Yourong and the Lingshan faction, who built the first parallel cargo plane.

Although he had only met Zhang Yourong once, Yan Liqiang felt like he had made a pen pal for this Lingshan faction, which was very interesting.

After Wen Zhaolun and the disciples of the Lingshan faction left Pingxi County, Yan Liqiang was in the manufacturing bureau, and Yan Dechang and a group of craftsmen in the manufacturing bureau started the imitation of the steam engine with enthusiasm.

To let the craftsmen of the Manufacturing Bureau and Yan Dechang invent the steam engine, they do not have this ability, but there is a ready-made steam engine as a reference, with the foundation of the Manufacturing Bureau and the ability of Yan Dechang and others, if you want to imitate, although it is a little difficult, but those difficulties can be solved, because the materials and processes for manufacturing the steam engine, as well as craftsmen, the Manufacturing Bureau is not lacking, of course, there is no shortage of money, not to mention that there is Yan Liqiang on the side to participate, as long as you draw a scoop according to the gourd......

Yan Liqiang returned to Pingxi County this time with the power of the big victory Feitianmen, the name of the first archery powerhouse in the northwest has been confirmed, and the whole person is as famous as the sky, and the name shocks the northwest, in these days when he is in the manufacturing bureau, all kinds of characters and worship posts from all directions fly towards the manufacturing bureau like snowflakes, but Yan Liqiang is in the name of retreat, so that people all refuse to decline, and the whole person devotes himself to the manufacture of the steam engine, because for Yan Liqiang, the significance of building this steam engine is definitely more important than his retreat, or rather, this is another form of retreat。

Disassemble, disassemble, measure, draw, mold, cast, fail, modify, summarize, cast, fail, modify, improve, and ......

After more than 20 days of dry work, when the willow trees outside the manufacturing bureau sent out new sprouts, and spring quietly came, the first steam engine in the manufacturing bureau was finally successfully imitated, as for the rotary grinding and circular saw blades used with this steam engine, these two things are relatively simple, they have been made seven days ago, and the steam engine sent by Lingshan has been matched and tried, the effect is very good, the efficiency of the rotating grinding and saw blades is many times higher than the traditional one, and it does not require labor, and now it is left in the manufacturing bureau, and the mill has begun to be used。

Looking at the flywheel that slowly began to rotate steadily after ignition, the craftsmen in the manufacturing bureau cheered, Yan Liqiang wiped the soot on his face, grinned, and said to Qian Su, "The manufacturing bureau will have another profitable business in the future, and in the future, in addition to the four-wheeled carriage manufacturing department, the manufacturing bureau will have one more water and fire machine manufacturing department......

Qian Su also laughed, "I'm afraid it will take a little time to sell!"

"As long as it is profitable, you can make money by buying this thing, and the speed of this thing will definitely be faster than that of a four-wheeled carriage, and someone will soon come to the manufacturing bureau to line up to purchase, and then it won't be long before other places as long as there is a little strength of the forces will start to imitate this thing......," Yan Liqiang said firmly.

"That's true!"

"Build two first, I'll give them away in two days!"

"Ah, to whom?"

"The Lu family!"

Qian Su was stunned for a moment, and then burst out laughing......
