Jingzhou, outside Xiangyang City.

Looking at the towering and towering Xiangyang City in the distance, a group of refugees were stunned, smacking the corners of their lips.

These people are just a group of people who are hard to raise rice.

Along the way, they went through a lot of hardships, inquired along the way, and then found them along the Yangtze River. The prosperity along the way had already opened their eyes.

When they saw the prosperity of Xiangyang City and the magnificence, they only felt a little unreal.

"Lord, Lord Lord, this... this city is too big, and the people here are dressed brightly, as if they are much better than ours!"

Next to Nanshengmi, a follower said, looking down at his robes, feeling a little sad. The queen of their mission took them the best clothes.

Although these clothes were washed a little white, they were made of the most precious table cloth of the Xiematai, which could only be worn by the officials and powerful officials of the dynasty.

But now... the tablecloth is no longer fragrant.

Because the people in Xiangyang wear better clothes than them, they even brought a bunch of tablecloths over, thinking that they could make the Han Dynasty admire them. Now it seems...

It's too difficult. How can the small country Doumi compare with the great Han Dynasty? No wonder they couldn't summon them just by Cao Cao's gift of some swords.

The face of Nanshengmi is not good-looking.

He asked himself that the tablecloth is a high-end cloth in the Xiematai, but getting this big man seemed to weaken their aura.

"I'm so fussy, I'm so calm that I'm not seeing the world before. How can I compare to the heavenly kingdom?" Nan Shengmi turned around and rebuked.

This group of little garbage has never seen the world.

Unlucky, too embarrassing.

Of course, he had never seen it, but had heard some rumors about the Celestial Kingdom.

They were close to the city, because they were all unkempt and not so energetic because they were rushing to the road during this period. At this time, they looked at the teams of soldiers guarding the gate and swallowed.

Tsk, this weapon is bright and huge.

"This general, I am the envoy of the Kingdom of Evil Matai, and I came to the Heavenly Dynasty to pay homage to the Emperor of Han and the Prime Minister of Han. This is the letter to my queen,"

"Oh by the way, there are only Bo Li, I hope the general will inform you."

Nan Shengmi clasped his fists and said embarrassedly.

"What country? Resisting horses? It's hard to live... rice?" The general guarding the city was stunned for a moment, his expression became a little strange, and his face was confused.

But no matter how he said that, he still looked behind.

When looking at the cloth, General Shoucheng twitched his lips, grinning and extinguishing a bitter smile, "You... your courtesy is indeed quite thin."

Oh my god, the cloth used by a group of ordinary people is really a gift.

It is also a bit embarrassing to find it difficult to increase the rice.

"Okay, you follow me!" The general guarding the city waved his hand first, signaled the A soldier to search, and then said.

For a moment, outside the Prime Minister's Mansion.

"Emuniques from hard to give birth, please come here later, I will report it to you." The general guarding the city said, and then left.

In the general's mansion, Jia Xu and others are correcting the documents.

The general guarding the city glanced, lowered his head and fisted and said, "Military advisor, a group of people have just arrived. He claimed that he was coming to Xiemaqiu and said that he would come to worship the emperor and lord. Will he see him?"

"Chen~? Did he mean the Kingdom of Evil Matai?" Jia Xu pondered for a moment and asked.

"Yes, yes, that's it."

"What are they here to do in the small island of Dongzhou?" Jia Xu frowned. He had known Xiematai in ancient books, but that place was much behind the great man and was not worth worrying about.

"Wenhe, Kong Ming had previously sent a message saying that Cao Cao might have won the Kesan Han and even entered the country of Yema. Do you think it was because of this?"

Chen Qun also put down his documents and asked.

Jia Xu pondered for a moment and said loudly: "If there is this possibility, the country is on a mission to a great man. It is rude to receive it. In this way, you can take them to settle down."

"I will inform the lord first, and the lord will decide."

"No!" The general guarding the city nodded and retreated immediately.

"Okay, I'll go and meet my lord." After Jia Xu said that, he walked away with great strides, and then turned around, "Do you two know where the lord is now?"

"It is estimated that 80% of them were in the Blacksmith Camp. After the lord returned to Jingzhou, he was obsessed with the Blacksmith Camp and used manpower and material resources to pave the road (track)"

Chen Qun said with a wry smile.

"What the lord saw and heard this time is a good thing. On the one hand, it shocked the Central Plains, and on the other hand, it can better help the people to survive the suffering. As for the road... it should be feasible."

Lu Su chose to believe unconditionally.

The focus of Chidao is on the painstaking maintenance, and the limited power of transportation, so it is gradually eliminated. However, Zhang Xiu’s success in Chidao is of great significance.

"I'll go and have a look!" Jia Xu nodded.

...

After a while, in the Blacksmith Camp.

In the middle of the open space, a group of people surrounded.

At this time, the blacksmith camp craft was ahead of the original Han Dynasty for many years with the interpretation of the previous craftsmanship. Zhang Xiu was welding things in the middle.

Jia Xu didn't say anything and stepped forward to watch.

I saw that in Zhang Xiu's hand there was a frame, with two gears one large and one small on the frame, and a chain was hung on the gear, and the pinion was fixed on a round steel rod.

Zhang Xiu originally wanted to use bearings and balls to reduce friction, but the current technology still couldn't make balls. He could only weld the gears and bearings to death, and directly used the gears to drive the rotation.

While driving, install the wheels on the other side of the steel rod, and then transfer the gear rotation power to the forward power, thereby realizing the forward train.

This is the principle, just like a bicycle.

However, the small train designed by Zhang Xiu is different. In order to ensure that the kinetic energy of the small train can be traction, each car must be equipped with a kinetic energy device.

That is, there are some of the two parts in front and back of each car for pedal capacity, and there is a small bucket in the middle to pull goods. You can also use the head-to-tail connection mode to better pull goods.

A cart of two people can transport 500 kilograms of grain in a car, and it can transport more than a hundred miles a day. This can greatly improve efficiency and reduce the disadvantages caused by transporting grain in a thousand miles a day.

"Come on, find a few wheels to try." Zhang Xiu shouted excitedly, regardless of the stains and sweat on his face, the gears were about to become the main transportation capacity.

After a while, Zhang Xiu began brazing.

This is an ancient welding technique. Although the firmness is not as good as iron welding in later generations, it is not bad.

Four wheels, bearing links.

A transmission is so good.

Although it is very simple, it was indeed made by Zhang Xiu, but the appearance needs to be improved, and the location needs to be improved in all aspects.

After a long time, the brazing ended.

A four-wheeler appeared.

Zhang Xiu did it excitedly, and then under the eyes of everyone, he stepped on the pedal and ran away...

However, this four-wheeler has no head and is only suitable for tracks. Zhang Xiu cannot ride too much, but this also proves the feasibility of his method.

But just stepped on it a few times,

Zhang Xiu felt the shortcomings.

First, because there are no balls, the gears and bearings are welded, so the pedal cannot be stepped upside down to adjust the position.

Second, because there is no bearing, it will be a little more laborious, and the feeling of being a bit slurry when stepped on is not as smooth as that of later generations.

However, in general, gear transmission devices can be produced in the late Han Dynasty, which is a big leap forward. At least it has some industrial foundation and will develop faster in the future.

When you go back and draw the points given by the system, you may be able to get some good things out, and it is not impossible to get a steam engine out then.
