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

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

"If the person next to him asks me, don't squeeze it here, this boiler will be hot..."

In mid-January, the snow was clear after the snow, the cold air faded slightly, and the snow on the ground had not yet completely melted. The yard of the Yan family's blacksmith workshop was already in full swing, and a large number of people surrounded the blacksmith workshop. They opened their eyes wide and watched the "iron lump" flywheel slowly rotated in the open space in the middle of the yard.

Yan Dechang, Zhou Tiezhu, and dozens of apprentices in the blacksmith workshop, a bunch of officials in the Yan family, plus Yan Liqiang, Shi Changfeng, Shi Dafeng, Chen Teng, Lu Peien, Qian Su, who came from Huanglong County, and several old craftsmen and craftsmen from the blacksmith workshop. Finally, there were Wen Zhaolun and a group of disciples from the Lingshan School. Everyone gathered in the yard and watched the "iron lump" sent by Lingshan Mountain slowly move after igniting the fire and adding water.

Except for a few people such as Yan Liqiang and Wen Zhaolun, everyone was in an instant when they watched the "iron lump" move, and Zhou Tiezhu shouted excitedly and trembled.

Yan Dechang, who had been fighting for the iron all his life, was stunned when he looked at the flywheel with faster speeds, and muttered to himself, "I have been fighting for the iron all his life, but I didn't expect that the fire and water could make the iron lumps move by themselves..."

Qian Su, a few old blacksmiths and craftsmen who came from the manufacturing bureau, staring at the rotating flywheel at this time, and he couldn't say a word, just like seeing something incredible. As for the expressions on the faces of other people like Shi Changfeng, they were basically the same at this time.

Yan Liqiang stood next to the steam engine that had just started assembled, looking at the rotating flywheel, his eyes swept over the parts on the steam engine, and his eyes were a little amazed. At first glance, this steam engine was like a stove more than one meter high. Below the steam engine was a few metal seats and frames. On the left side of the frame was a fire-making boiler similar to the stove. The boiler was made of iron. On the boiler, there was also a bright yellow cylindrical water tank made of brass. The water tank was roughly It is one meter long and 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 discharged, and some are discharged. In the middle of the copper pipes that emit air, there is a manual valve that can adjust the intake volume. This intake pipe connects the most important cylinder of the steam engine. Above the cylinder is a piston and a crankshaft connecting rod. A circular rotating flywheel with a diameter of about 50 cm is on the other side of the crankshaft connecting rod. As the piston in the cylinder moves, the flywheel also rotates quickly under the action of the connecting rod.

But what really surprised Yan Liqiang was not these, but the device that condensed the steam input into the cylinder located under this steam engine. You should know that in the past life, this condensation device was created by Watt after the steam engine was invented for a long time. The initial steam engine had two obvious disadvantages. One was that the piston was discontinuous and slow, and the second was that the steam utilization rate was low and waste raw materials. The most important reason for this problem was that steam condensed in the cylinder. Watt's greatest contribution to the steam engine was to convert the traditional steam engine from condensation in the cylinder to outside the cylinder. After Watt completed this improvement, the basic mechanism of the steam engine was completely stabilized and then it began to become popular.

Yan Liqiang originally thought that the steam engine that Zhang Yourong built for the first time would not think of the outside-cylinder condensation method, but what he did not expect was that the steam engine sent from Lingshan had already adopted the outside-cylinder condensation method. In this way, the reliability and stability of this steam engine have been greatly improved and can definitely meet the standard of practical investment.

Yan Liqiang was secretly amazed in his heart. Zhang Yourong is worthy of being Zhang Yourong. But after being pointed out by himself, after a year, the steam engine built by Zhang Yourong was already very complete. The steam engine built by Lingshan School Qianjitang was already very close to the structure of the mature single-cylinder steam engine in his mind. Although some details seem to be a bit rough at first glance, the basic mechanical structure and usage functions are fully equipped.

The two disciples of the Lingshan School Qianji Hall were operating the steam engine in front of him. Wen Zhaolun stood beside him, looking at the iron lumps made by the Lingshan School Qianji Hall with some pride. When Zhang Yourong returned to Qianji Hall, he highly praised Yan Liqiang. He once told Wen Zhaolun that Yan Liqiang's attainments in the art of studying things were unfathomable and might be above him. Although Wen Zhaolun had always admired Zhang Yourong's ability, he was somewhat reserved for Zhang Yourong's words to praise Yan Liqiang. Before coming to Ganzhou, he did not believe that a young boy in his teens could study things in the art of studying things.

His attainments can be comparable to Zhang Yourong, the master of the Han Empire's first organ, but after coming to Ganzhou, he had seen Yan Liqiang's ability in the bow path in Tianchi, Canglong Mountain. Wen Zhaolun was indeed impressed by Yan Liqiang and was a little shocked. However, when it comes to the way of investigating things, he still felt that Yan Liqiang could not be more powerful than Zhang Yourong. Zhang Yourong said that the idea of ​​the iron lump in front of him was thought of by Yan Liqiang. Even after seeing Yan Liqiang, Wen Zhaolun always felt that Yan Liqiang might just be a blind cat to meet a dead mouse. His head flashed with a flash of inspiration. The real powerful figure was of course the Lord Zhang of their Qianji Hall.

The expressions and shock on the faces of the people around him made Wen Zhaolun, the deputy master of Qianji Hall, very satisfied. I remember that when he first saw the thing Zhang Yourong made, it was almost the same expression. The stunned look on the face of the people was in Wen Zhaolun's opinion, it seemed like a speechless praise to the Lingshan School and Qianji Hall, which made him very useful. When Wen Zhaolun's eyes turned to Yan Liqiang's face, the deputy master of Qianji Hall was slightly stunned. Because Yan Liqiang's expression was not shocked at all, he looked at the "unprecedented" machine made by the Lingshan School Qianji Hall with a playful look.

Shouldn’t you look shocked and admired when you see something like this that no one can create? What does that mean?

Wen Zhaolun felt a little unhappy, "Cough... cough... Master Yan thinks how is this water lighter made by our Lingshan School Qianjitang?"

The water and lighter, a slightly weird name that Yan Liqiang sounded to him, was 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 is indeed worthy of being the first master of the great Han Dynasty. The water...water and water lighter made by Qianjitang is definitely the first in the Silver Continent. I admire it, admire it!" Yan Liqiang praised with a smile.

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

"Li Qiang, how can the rotation of this flywheel slow down..." After staring at the 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, look, the valve on the copper pipe can be controlled. Pull the valve up a little, the flywheel will slow down, open a little bigger, and the flywheel will rotate faster..." Yan Liqiang said as he walked over, and took the steam valve connected to the boiler copper pipe to demonstrate.

Seeing Yan Liqiang take action, Wen Zhaolun and several disciples of the Lingshan Sect next to him were stunned for a moment. They didn’t even say how to control the water and lighter. How could Yan Liqiang know at a glance?

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

"That's because after the water in this copper water tank is heated, the steam generated will enter the cylinder from the copper tube. This valve controls the size of the steam in the copper tube. If the steam is small, the speed of the flywheel will be slow. If there is more steam, the speed of the flywheel will be fast!" Yan Liqiang pointed to the steam engine and explained, "You must be careful when using this thing. If the boiler under the water tank is still burning, the valve cannot be completely closed. After the ventilation valve is closed, a deflation switch here must be opened. If all the valves are closed to burn water, the water tank will explode, which is very dangerous. If there are people next to you, there may be casualties..."

"Oh, will this thing explode?" Zhou Tiezhu asked in surprise.

"certainly!"

Wen Zhaolun was already surprised, because when he first started researching and manufacturing this thing in Qianjitang, it turned out to be as Yan Liqiang said, something happened. Fortunately, the accident did not hurt anyone. When the boiler exploded, there was no one around, and just made a workshop mess. Since then, Zhang Yourong thought of installing a deflation port for the boiler...

"I heard from the hall master that Mr. Yan's attainment in the way of investigating things in the mechanism is extraordinary. After seeing this water and lighter, can you guess where our hall master spent the most effort to build this thing?" Wen Zhaolun asked again without giving up.

Yan Liqiang smiled slightly and pointed to the inconspicuous condensation device under the cylinder. "The water and lighters that you Qianjitang first built are not available. This thing must have been made by Brother Zhang in the last place. It was also made by Brother Zhang who has experimented countless times and spent a lot of time and energy. I wonder if I guess it right!"

"Ah..." Wen Zhaolun looked at Yan Liqiang in amazement. The disciples of the Lingshan Sect next to him looked at Yan Liqiang's eyes, as if they had seen a ghost. The so-called expert can tell if there is anything when he stretched out his hand. Yan Liqiang instantly silenced Wen Zhaolun and several Lingshan Sect disciples in a simple sentence.
