Liu Yun met everyone present one by one, whether familiar or unfamiliar.

This made everyone gradually let go of the awe they didn't dare to look at Liu Yun, dare to look directly, and dare to speak.

Liu Yun is different from the past, and there is a kind of majesty in his body that makes people tremble.

That is probably the majesty of the legendary superior, although Liu Yun didn't feel that way, nor did he feel that he was now in command of so many people, as if he had become different, he was still the same person he used to be.

But in the eyes of others, the current Liu Yun is no longer the Liu Yun who used to dig stones on Izumo Mountain.

He is now not only the lord of Hanyang, his territory has expanded to almost the entire Liangzhou, as well as five counties in the Central Plains and one county in Yizhou.

Wang Yun'er walked timidly in front of Liu Yun, with a restrained smile and a hint of the shyness of the girl next door.

"Brother Yun!" Wang Yun'er whispered crisply.

Even though Wang Ting and Wang Zhi asked several times, she still stubbornly wanted to call Brother Liu Yunyun.

Perhaps, in Wang Yun'er's heart, this title is the only thing that can bring her and Liu Yun closer.

Liu Yun touched Wang Yun'er's head dotingly, and said, "I haven't seen you for half a year, my Yun'er has become more intelligent and has grown up." ”

The words from Liu Yun's mouth have grown up, this time, they have grown up seriously, not some worthwhile meat words.

But Wang Yun'er, who has had several experiences, heard Liu Yun's words, and involuntarily looked down at a certain place in herself, and blushed in an instant, like the peach of March, delicate and gorgeous.

"Brother Yun is still so bad, he makes fun of others as soon as he comes." Wang Yun'er muttered shyly and hung her head timidly.

Liu Yun was stunned, what he just said was very serious.

Hearing Wang Yun'er's words, she couldn't help laughing, and after a closer look, Yun'er's girl has indeed grown up.

The changes in the past six months are indeed quite large.

"Let's go, let's go up the hill, we're grown girls." Liu Yun greeted Wang Yun'er with a smile.

Under the arch guard of the Eagle Guard, Liu Yun led the crowd up the mountain.

After a toss of the emperor's name, Izumo Mountain can hardly see what it once was.

Many of the mountain peaks are connected by chain bridges or arch bridges.

On the mountain, pavilions and pavilions are lined up one after another.

At the foot of each mountain, there is a pass, which is guarded by a team of soldiers.

The residents of the neighborhood who had originally moved to the mountain were now concentrated in the dock at the bottom of the mountain, where there are now thousands of households, tens of thousands of people, and the largest market in the vicinity.

And this mountain is now where the yamen of Hanyang are located.

Each yamen occupies a mountain, and the division of labor is clear.

The real yamen in Hanyang is mainly in Ji County, and the yamen here is the various bases that Liu Yun said.

For example, Hanyang's largest iron workshop and gunpowder workshop are now collectively called Craftsman.

Liu Yun did not go to the new home prepared by the emperor for him, which was located on the misty Lantern Festival Peak.

Instead, he went to the small courtyard where he used to live.

Everything in the entire Izumo Mountains has changed, but only here, it remains the same as it once was.

There is also someone who cleans it every day to keep everything neatly organized.

Sitting down under the big locust tree in the courtyard, Zhuo Gang couldn't wait to start asking Liu Yun a lot of questions.

His upright temperament doesn't care if this occasion is suitable or not.

Those questions had been in his head for a long, long time, and if he couldn't think of answers, he would go crazy.

For Zhuo Gang's talent, Liu Yun was tolerant to the extreme, and listened very carefully and patiently.

"My lord, the engine you describe in the book is made of coal burning, which produces steam and then power, and then can drive the carriage forward on its own, and as soon as the lowly duty has free time, he arranges for the idle craftsmen in the craftsman department to ponder this matter, and we agree that this must meet one condition, that is, there must be a vessel, which can turn steam into a vessel, in order to do so." Zhuo Gang put the design in front of Liu Yun and said.

A large group of people on the side watched curiously, but let alone the drawings, they couldn't even understand what Zhuo Gang said.

Liu Yun glanced at several design drawings drawn by Zhuo Gang, and said: "Zhuo Gang, the problem you are thinking about now is actually a little too profound, and the steps are too fast. If you can get the balls out first, I don't think it's far off. ”

"My lord, but I am entangled in this problem, it is definitely a huge change for the whole society to change the original way of traveling in a horse-drawn cart, and to use this way of travel, which does not require manpower, only coal and water can achieve the purpose of progress." Zhuo Gang scratched his hair that seemed to have not been washed for many days, and said stubbornly.

Liu Yun nodded and said, "It seems that you are attracted by this thing." If you want to figure out how something comes from, you must first figure out its principle, the principle of the steam engine is that it converts the energy of steam into mechanical energy that repeats itself. ”

The guards immediately fetched a pot of water, set it on the stove, and made a fire to boil the water.

That's right, the stove has been used on Izumo Mountain for a long time, and Liu Yun's current state is probably like the countryside in the past, drinking pots of tea around the stove.

"Zhuo Gang, come! Look closely, what happens when this water boils? When the water was about to boil, Liu Yun greeted Zhuo Gang, who was burying his head in sorting out his notes.

Zhuo Gang, who had a messy beard, came over, staring at the movement of the kettle without blinking with both eyes.

On the other side of the stove is the name of the emperor who is also a little enchanted.

He is also half an idiot in this regard.

"The lid has moved!" Zhuo Gang suddenly shouted.

Liu Yun nodded and said: "Actually, all great innovations come from our lives, this phenomenon, I believe many people have noticed, but it did not cause associations, and did not use their brains to think about what was going on." When water is boiled, it becomes gaseous, and we feel damp because the water vapor is suspended in the air, and then to the sky, the colder the water vapor becomes, and it condenses into clouds. At this high temperature, the very active water vapor is a kind of force, a force that can drive the carriage to walk. Of course, that's not enough. ”

"Just like when a person is full of food, he has the strength to fight and work, but the premise is that we have to be a person with sound limbs, but when we are full, without arms or legs, he will not be able to fight and work. So, what you're going to figure out now is how to put your arms and legs on the water vapor and make it move. ”

Zhuo Gang fell into deep thought, and Huangfu drew a person on the ground.

Then, the two of them began to settle face to face.

As soon as Liu Yun saw this state, he knew that these two people were enchanted again, so he simply stopped bothering, but began to meet the next question.

Everyone in this circle has problems.

On this Izumo Mountain, Liu Yun is not only the lord, but also a mentor.
