Huang Wan is only twenty-six years old this year, and she still maintains a strong curiosity about new things, and Liu Yu specially arranged for Zhong Yu to take her around, and saw many things in the factory that she had never seen or even thought about.

"Look at this thing. She handed Ding Kui a palm-sized object.

When Ding Kui looked at it, his eyes bulged so much that they were about to fall out, "Gear!"

That's right, what Huang Wan gave him was a round gear, and the shape looked very standard.

"Gear? That's an interesting name, do you think I'm doing a good job?"

"What did you do?" Ding Kui looked at Huang Wan with an incredulous expression.

"Well, but a carpenter gave me a sample, is there something wrong with it?" Huang Wan was a little nervous.

"Yes, yes, very well done!Ah, you're an earthly magician.

All metals are made of earth elementals, but I didn't expect you to have that much control. ”

Ding Kui was relieved when he thought of Huang Wan's identity.

"How long does it take you to make a gear like this?"

Huang Wan showed a bright smile and replied, "It didn't take long, less than a stick of incense." ”

"Oh, at least ten minutes, too. Ding Kui was calculating in his heart.

"This is the first time I've done it, and it should take me less time to do it later. Huang Wan thought that Ding Kui thought she was slow, so she hurriedly explained.

"Hehe, there is no precision mechanical production, it is already very fast. Ding Kui looked at it and knew that people had misunderstood, "How much magic does it cost you to make one?"

"Oh, it doesn't cost much mana, and it will save some mana after it is melted, but it will take some mental power. ”

"That's for sure. Ding Kui can understand that the inner ring of the gear on his hand is a standard circle, and the spacing between each spur and the spacing of the slug is exactly the same.

"It's more than controlling the magic stack, but it's just enough to train my mental power. "Huang Wan's unique skill is to use two minds, her mental power is already stronger than her peers, and she still cares a lot about the method of exercising her mental power.

She watched Ding Kui turn around her, and her eyes seemed to show a greedy light.

With her help, you can make a precision machine tool, and build a waterwheel where there is a river, which can improve production efficiency.

Ding Kui almost drooled and saw the prospect of industrialization.

"What else are you going to do besides this?" he pondered how to dig up the "treasure" in front of him.

"By the way, I heard that you want to make a long iron bar, I should be able to help you, and so many other things. ”

Huang Wan had a lot of ideas, especially after chatting with the craftsmen in Hengfu City, she found that she could do everything that the craftsmen couldn't do.

"Iron bars, railroad tracks!" Ding Kui almost jumped up, and his excited appearance startled Huang Wan.

He had been thinking about laying railways, and there were two major obstacles, one was the railroad tracks and the other was the locomotive.

The locomotive head is responsible for providing power, which can be replaced by other powers, such as war horses, to solve the problem of starting and braking, war horses can pull the carriage, can reach an average speed of thirty or forty kilometers per hour, and the transportation and logistics industry can take off.

The most difficult thing is the railroad, which is dozens of kilometers long and has the same shape and size, which is a dead knot that restricts the development of rail transit in Dingkui's territory.

"That's right, that's right, if you make the gears, the rails will be even more problematic!Oops, it's really a great favor for me!" He wanted to hug Huang Wan, but after all, she was a big girl with yellow flowers, and it didn't have a good impact if she really hugged her.

"That iron, is the rail important?" Huang Wan was confused.

"Important! Very important! You said that the road from Hengfu City to Juyang City is uneven?"

"Ping. ”

"How long does it take for ordinary people to walk from Hengfu City to Juyang City?"

"I'll have to walk for half a day. ”

"As long as the railroad tracks are made, I can shorten this time to more than an hour, do you say it matters?"

"More than an hour!" Huang Wan blinked, "It's so fast, it's almost like riding a horse, and the connection between Giant Sheep City and Hengfu City will be closer in the future, which will be beneficial to the future development of the guild." ”

The apprentice who is in charge of the general association knows how to think about the development of the magic guild, and she can understand Ding Kui's thirst for railroad tracks.

"That's right!" Ding Kui rubbed his hands excitedly, "Not only can those two cities be connected to other cities, such as the county seat, port city, etc., but the entire Nanqiu County can be connected by railroad tracks." ”

"Yes, yes, what does the railroad track look like?" Huang Wan was infected by Ding Kui's emotions, and she couldn't wait to make the railroad track immediately.

"Wait, I'll draw you a pattern. ”

In his previous life, Ding Kui was a railway child, his parents and many relatives worked on the railway, and his family lived next to the railway, so he was very familiar with trains and railroad tracks, and it can be said that he could draw railroad tracks with his eyes closed.

"Oh, these are the rails, they're so simple, they're much easier than making gears. Huang Wan was relieved when she saw the pattern of the railroad tracks, she could definitely make it with her ability.

"Yes, it's very simple, you can definitely do it, ordinary craftsmen can do it, but it is too time-consuming, and there is a large error in the size of the front and back, not as fine as you do. ”

Ding Kui has confidence in Huang Wan.

"That's it, tomorrow I'll go to Nanping County with you, and you try to make a few meters long. ”

It was inconvenient for him to let Huang Wan try it in the barracks, this was his private matter after all.

Now that there is no sign of a large-scale attack by his own people, the Zhongbei Route Army rested in Ji'an County after the Battle of Baimeadian, and the new army, which suffered a setback for the first time, needed time to adjust its mentality; after sending the 20th Army Corps back to Shaodian State, there was no movement, and it was still a question whether the Northern Route Army would be returned to his command.

The Shaodian Army also had no time to attack, and the 20th Army Corps retreated to the county town of Nanping to recuperate, needing to replenish new troops and waiting for the wounded to return; the 8th Army Corps rebuilt the destroyed defensive line on the border, and after its own country was no longer a friendly alliance, it was necessary to increase the defense facilities in the border area, and watchtowers and outposts were indispensable.

Ding Kui's division was responsible for guarding the border, and the first task was to prevent the first wave of attack by his own army, which was not very difficult for the 74th and 75th divisions, and Ding Kui could take time to leave for a while.

"What are you talking about?" Ruan Xingzhu didn't hold back and ran to the Zhongjun tent to observe. Ding Kui took the gear to explain to her, and at the same time introduced the comrades in the knight competition.

"I don't know anything about the earth element, so I can't really do it. She had to admire Huang Wan after watching the gears.

The four major magicians have their own strengths, the qi system will teleport to make people enviable, and the earth system's land control and gold control are also a must, and it is not surprising that the Son of the Wind lost to Huang Wan in crafting metal items.

"I'm just now realizing that I didn't have a single earthly mage friend before, and you're the only one. Ding Kui thought back to all the magicians he knew.
