"It's moving, it's really moving, this iron lump is moving......"

"Prepare the coals, be careful, don't let the fire go out......"

"The people next to you let go, don't squeeze here, this boiler will be hot......"

In the middle of January, the snow was clear, the cold had faded slightly, and the snow on the ground had not completely melted away, and the courtyard of the Yan family's blacksmith workshop was already in full swing, bustling, and a large number of people surrounded the blacksmith workshop, and their eyes widened one by one, looking at the "iron lump" flywheel in the open space in the middle of the yard slowly turning.

Yan Dechang, Zhou Tiezhu, and dozens of apprentices and disciples in the blacksmith workshop, a bunch of stewards of the Yan family, plus Yan Liqiang, Shi Changfeng, Shi Dafeng, Shen Teng, Lu Peien, as well as Qian Su who came from Huanglong County and several old craftsmen and craftsmen in the blacksmith workshop, and finally Wen Zhaolun and a cadre of disciples of the Lingshan faction, everyone gathered in the courtyard, watching the "iron lump" sent by the Lingshan faction slowly move after igniting the fire and adding water.

Except for a few people such as Yan Liqiang and Wen Zhaolun, after watching the "iron pimple" move, everyone was in an instant uproar, and Zhou Tiezhu's voice shouted excitedly with trembling.

Yan Dechang, who has been playing iron all his life, looked at the flywheel that was spinning faster and faster, and he was also dumbfounded, and the whole person muttered to himself, "I have been playing iron all my life, but I didn't expect that this fire and water can make the iron lumps move by themselves......"

Qian Su and a few old blacksmiths and craftsmen who rushed from the manufacturing bureau couldn't say a word when they stared at the rotating flywheel at this time, as if they saw something incredible, as for the expressions on the faces of others such as Shi Changfeng and others, they were basically the same at this time.

Yan Liqiang stood next to the steam engine that had just been started and assembled, looking at the rapidly rotating flywheel, his eyes swept over the parts on the steam engine, and there was some amazement in his eyes- At first glance, this steam engine is like a stove more than one meter high, under the steam engine, there are several metal seats and frames, on the left side of the frame, is a stove-like stove-like fire-making boiler, the boiler is made of iron, on the boiler, there is a bright yellow cylindrical tank made of brass, the water tank is about a meter long, the bucket is thick, on the top of the water tank, there are several copper pipes, some copper pipes are filled with water, some copper pipes are vented, and there are deflated, in the middle of the copper pipe that is vented, there is also a manual valve that can adjust the amount of air intake, this air intake pipe is connected to the most important cylinder of the steam engineOn the cylinder is the piston and the crankshaft connecting rod, a circular rotating flywheel with a diameter of about 50 centimeters, on the other side of the crankshaft connecting rod, as the piston in the cylinder moves, the flywheel also rotates rapidly under the action of the connecting rod.

But what really amazed Yan Liqiang was not these, but the device that condensed the steam input into the cylinder under the steam engine, you must know that in the previous life, this condensation device was invented by Watt for a long time after the steam engine was invented, the original steam engine had two obvious shortcomings, one is that the piston action is not continuous and slow, the second is the low utilization rate of steam, waste of raw materials, the most important reason for this problem, is the condensation of steam in the cylinder, Watt's biggest contribution to the steam engine, is to condense the traditional steam engine, from the condensation in the cylinder to the condensation outside the cylinderIt was only after Watt completed this improvement that the basic mechanism of the steam engine was completely stabilized, and then it began to flourish.

Yan Liqiang originally thought that the steam engine that Zhang Yourong built for the first time would not think of the method of out-of-cylinder condensation, but what he didn't expect was that the steam engine sent by Lingshan had already adopted the method of out-of-cylinder condensation, so that the reliability and stability of this steam engine had been greatly improved, and it could definitely reach the standard of putting it into practice.

Yan Liqiang was secretly amazed in his heart, Zhang Yourong deserved to be Zhang Yourong, but after being broken by himself, after a year, the steam engine built by Zhang Yourong was already very complete, and the steam engine created by the Lingshan School Qianjitang in front of him was very close to the structure of the mature single-cylinder steam engine in his mind, although some details were still a little rough at first glance, but the basic mechanical structure and use functions have been fully possessed.

Running the steam engine in front of him are the two disciples of the Lingshan Sect Qianjitang, Wen Zhaolun is standing next to him, looking at the iron lump made by the Lingshan Sect Qianjitang with some pride, when Zhang Yourong returned to the Qianjitang before, he respected Yan Liqiang, and once said to Wen Zhaolun that Yan Liqiang's attainments in the art of the organ are unfathomable, and it may be above him, although Wen Zhaolun has always admired Zhang Yourong's ability, but when he praised Yan Liqiang for Zhang Yourong, he had some reservations in his heart, before coming to Ganzhou, He didn't believe that a teenage boy could be comparable to Zhang Yourong, the first organ master of the Han Empire, in the way of organ grids, but after coming to Ganzhou, he had seen Yan Liqiang's ability in the archery in Tianchi, Canglong Mountain, Wen Zhaolun was indeed impressed by Yan Liqiang, and was a little shocked, but when it came to the way of organs, he still felt that Yan Liqiang could not be more powerful than Zhang Yourong, Zhang Yourong said that the idea of the iron pimple in front of him was thought up by Yan Liqiang, even after seeing Yan Liqiang, Wen Zhaolun always felt that Yan Liqiang might just be a blind cat and a dead mouse, and his head flashed with an idea, a really powerful character, of course, it is still the master of their Thousand Machines Hall.

The expressions and shocked looks on the faces of the people around him made Wen Zhaolun, the deputy hall master of the Thousand Machine Hall, very satisfied, I remember that the first time he saw this thing made by Zhang Yourong, it was almost this look, the stunned look on the face of the dry people, in Wen Zhaolun's opinion, it was like a wordless praise for the Lingshan Sect and the Thousand Machine Hall, which made him very useful, and when Wen Zhaolun's eyes turned to Yan Liqiang's face, the deputy hall master of the Thousand Machine Hall was slightly stunned, because the look on Yan Liqiang's face was not the slightest shock, but with a playful and somewhat scrutinizing look at this Lingshan Sect Thousand Machine HallA machine that has never been seen before.

Shouldn't it be a look of shock and admiration to see something like this that no one can create? What does that mean?

Wen Zhaolun was slightly unhappy in his heart, "Ahem...... Cough...... What does Yan Gongzi think of this water and fire machine built by our Lingshan Sect Thousand Machine Hall?"

The name of the water and fire machine, which sounds a little strange to Yan Liqiang, is the name given to this steam engine by Lingshan, to put it simply, it is a machine that can be driven by the power of water and fire.

"Brother Zhang really deserves to be the first organ master of the Han Dynasty, this ...... made by Qianjitang Water...... The water and fire machine is definitely the first in the Silver Continent, admire, admire!" Yan Liqiang praised with a smile.

Hearing Yan Liqiang say this, Wen Zhaolun finally showed a smile on his face, feeling that Yan Liqiang was quite modest.

"Liqiang, how can the rotation of this flywheel slow it down......" After staring at this steam engine for a long time, Yan Dechang couldn't help but ask a question.

"Oh, it's actually very simple to slow down this flywheel, father, you see, the valve on the copper pipe can be controlled, pull the valve up a little, the flywheel will slow down, open bigger, the flywheel will rotate faster......" Yan Liqiang said as he walked over and took it upon himself to pull the steam valve connected to the boiler copper pipe to demonstrate.

Seeing Yan Liqiang's move, Wen Zhaolun and several disciples of the Lingshan Sect next to him were stunned for a moment, they hadn't said anything about how to control this water and fire machine, how could Yan Liqiang know it at a glance?

"Then why can this valve control the speed of this flywheel?" Zhou Tiezhu also scratched his head and asked.

"That's because after the water in this copper tank is heated, the steam generated will enter the cylinder from this copper pipe, and this valve is to control the size of the steam in the copper pipe, the steam is small, the speed of the flywheel is slow, and the more steam, the faster the speed of the flywheel!" Yan Liqiang pointed to the steam engine and explained. Just be careful when using this thing, if the boiler under this tank is still burning, this valve can not be completely closed, after the ventilation valve is closed, a vent switch here must be opened, if all the valves are closed to burn water, after a long time, this tank will explode, very dangerous, if there are people next to it, there may be deaths and injuries......"

"Oh, this thing will still blow up?" Zhou Tiezhu asked in surprise.

"Of course!"

Wen Zhaolun was already surprised, because when Qianjitang started to research and manufacture this thing at the beginning, it was really like Yan Liqiang said, something happened, fortunately, no one was injured in that accident, when the boiler exploded, there was no one around, just made a mess of a work workshop, and after that, Zhang Yourong thought of installing a vent for this boiler......

"I heard from the hall master that Yan Gongzi's attainments in the way of organ objects are extraordinary, so Yan Gongzi looked at this water and fire machine, can you guess where our hall master spent the most effort to make this thing?" Wen Zhaolun asked again with some reluctance.

Yan Liqiang smiled slightly, and pointed to the inconspicuous condensation device under the cylinder, "There is no such thing on the water and fire machine that you Qianjitang first built, this thing must have been made by Brother Zhang last, and it was also Brother Zhang who experimented countless times and spent a lot of time and energy to get it out, I don't know if I guessed right!"

"Ah......" Wen Zhaolun looked at Yan Liqiang dumbfounded, and the disciples of the Lingshan Sect next to him looked at Yan Liqiang's eyes, it was like seeing a ghost, as soon as the so-called connoisseur stretched out his hand, he knew if there was any, Yan Liqiang just said a simple sentence, and instantly stopped Wen Zhaolun and several disciples of the Lingshan Sect.

"Uncle Qian, do you think the Manufacturing Bureau can also make this thing?" Yan Liqiang turned his head and asked Qian Su......
