Ahead, Xun Yu gave Zhao Hu a hope, that is, the Han army was on the way to come, hoping that he would stick to his last position.

This is the tactic that Zhou Yafu used back then, and it is still easy to use on Zhao Hu.

With the promise of the envoy of the Han Dynasty, Zhao Hu desperately led people to resist, and finally resisted Lü Jia's attack.

Lu Jia couldn't attack Zhao Hu's last city, and began to attack Su Ying jointly with Yu Yushan. Halfway through the battle, Yu Shan and Yu Ying reconciled, and began to jointly attack Lu Jia again.

Fortunately, Lu Jia is a veteran minister for many years, and he still has his own set of routines for using soldiers to secure the people, and he barely supports the attack of Su Ying and Su Yushan.

The chaos in the Baiyue region is not something that ordinary people can solve.

Taking advantage of their confusion, the Han Dynasty had already begun to develop the Southwest Yi.

Yan Ming and his students surveyed the terrain and studied the paving of the railway. Even if you can't build a train, running on the tracks with a horse-drawn carriage can increase the speed a lot.

When Yan Ming was worried about the key process of the steam engine, the elder Chen in the north came with good news.

He succeeded in assembling the steam engine. Just won't use this kind of thing.

Yan Ming listened, and immediately said goodbye to Liu Che, and rushed to Cloud City in the starry night.

Last time, I hurried through Cloud City and didn't meet Wei Qing and the others, but this time it was different.

Wei Qing greeted him from afar.

The border city is more prosperous.

There was an endless stream of merchant vehicles, some going inside, some going out.

"Look, this is my big man's caravan. At present, it is all controlled by the military. These supplies were sent to the Huns. They consume a lot of money in war, and they often come to us to buy all kinds of supplies. Wei Qing said with a smile.

"Are you still supporting Yu Shan?" Yan Ming asked.

Wei Qing said with a smile: "Yu Shan also supports it, and Yi Zhixie also supports it." Do business, smile and welcome customers from all directions. ”

The two brothers laughed when they said this.

"The two of them can hold on, but they haven't been defeated yet."

"It's coming. Han Yan used thunderous means to integrate Xianbei and Touman, and with the consent of His Majesty, he dispatched 10,000 soldiers and horses from me to guard that place. In the final analysis, this matter is still your credit, and the territory of my Han has increased a lot. Wei Qing said.

"I hope Han Yan won't be too thunderous, and don't force the two nations against each other." Yan Ming said.

"No, that kid is fine." Wei Qing and Yan Ming laughed, and the two walked side by side and entered Cloud City.

Yan Ming couldn't wait to see the steam engine, and told Wei Qing, who was also very curious about what this steam engine could be used for.

The two of them, with the guards, walked directly to the blacksmith camp of Da Lao Chen.

Today, after replanning, the blacksmith camp has become the equivalent of an iron-smelting factory in Cloudsdale. Da Lao Chen is the director of this iron-smelting factory.

After receiving the report, the eldest elder Chen had already stood outside the blacksmith camp waiting for Yan Ming and Wei Qing to arrive.

"Master Hou, you want me to die." If someone else said so, Yan Ming would definitely not believe it. But Da Lao Chen is different, this person doesn't know how to do any tricks.

Yan Ming jumped off the war horse and hugged the elder Chen fiercely.

"Master Hou, the elder Chen Xing lived up to his fate and created a steam engine. Let's see, whether it's good or not. "Elder Chen is more anxious than Yan Ming, and he doesn't know if what he makes is what Yan Ming wants.

Yan Ming followed the elder Chen and walked in quickly.

Wei Qing also followed closely, he also wanted to see what it was that made Yan Ming pay so much attention to it and deliberately came from Chang Anna's side.

The most hidden place in the blacksmith camp, there is an empty field.

In the middle was a platform on which a machine was covered with a heavy coarse cloth.

Yan Ming knew that it was the steam engine.

He walked up briskly and tore the coarse cloth open.

The smell of oil came to my face.

"Who's on the oil?" Yan Ming asked.

Elder Chen took a step forward and said, "I'm on it." In the process of production, it was found that the transmission effect between the connecting rods was better if a little oil was smeared on the top. Is there anything that doesn't work? ”

Yan Ming patted him on the shoulder and said with a smile: "There is nothing that can't be done, what you did is right." ”

If you look closely at the steam engine, every link is tightly knit and the workmanship is quite fine.

"Lao Chen, how did you do this?" Yan Ming asked curiously.

Elder Chen smiled and said, "There's no good way." I was in a hurry, so I polished it little by little with my hands, and everyone studied it together. ”

Handmade steam engine!

Who said that the ancients were underdeveloped. Even if such a craftsman is placed in the future generations, it will be scrambled by various enterprises.

Yan Ming bowed to Elder Chen and said, "This machine, if it can operate normally." Yan Ming salutes you for all the people in the world. ”

The elder Chen never thought about how useful this steam engine was, and when he saw Yan Ming solemnly giving himself a salute like this, while dodging, he generally shook his hand and said: "Hou Ye is serious, this drawing is all from Hou Ye, and the elder Chen paints the scoop according to the gourd, and there is no credit." ”

Yan Ming didn't argue with him, and asked people to add water to the steam engine, and then began to light and heat it.

Everyone didn't know what Yan Ming was going to do, and they all watched curiously.

Wei Qing even came up and asked, "Fourth, what's the use of such a big piece of iron?" I don't think it's as good as building some military crossbows and swallow knives. ”

Yan Ming said with a smile: "Third brother, with this thing, my Han Dynasty can unify the world." ”

"Global?" Wei Qing was stunned.

He didn't understand the concept of the world.

Although Yan Ming had said before that the place where they lived was actually a ball, Wei Qing always felt that Yan Ming was talking nonsense. If it's a ball, isn't the person below going to fall?

"You mean this thing can be used as a weapon?" When it comes to the military, Wei Qing has always been very enthusiastic.

Yan Ming nodded and said, "With him, maybe you can replace the cavalry!" ”

It's just a pity that there is no gasoline at this time. Otherwise, starting from the age of steam, with his advanced knowledge, he may be able to build gasoline engines and diesel engines.

For the smelting of gasoline, crude oil is needed.

Yan Ming thought of crude oil, and suddenly thought of several places.

One is Xinjiang and the other is Shandong Sea. There is also a place in the northeast of Daqing.

At present, Xinjiang is still an area controlled by many countries and ethnic groups, and even the Anxi Protectorate has not yet been opened. Naturally, it is impossible to go there and extract oil.

Ludi's oil is mainly at sea, and it is not easy to extract.

However, the place where the Xianbei people and the Touman tribe lived, which was the place where the Heilongjiang and eastern Inner Mongolia of later generations were located. There's a big oil field there.

Yan Ming was thinking of the big oil field when he suddenly heard everyone exclaim.

I saw that the steam engine, which was quiet just now, was heated for a while, and under the strong pressure difference between the steam and the outside world, the linkage rod moved slowly and slowly pushed forward.

The whole machine made a loud noise, like a drum.

The steam engine, moved.
