Huo Guang carefully looked at the steel war horse in front of him, this was the first mechanical creature he owned, although its body was not a thousand-mile fast horse, but it was also the highest-grade horse that Ganfu could find in this county town.

Because the mechanical creatures have to build their bodies according to the creatures themselves, they will theoretically choose taller and stronger war horses to build, and no one wants their mounts to be much worse than others' in appearance, and it is easy to lose their prestige.

Huo Guang can't waste this steel horse, it will be difficult for him to have a second one in a short time, Ganfu is about to leave, there is still a long way to go before he can build it, if this steel horse is scrapped by him, he can only go and beg Huo Qu to give one at that time.

Circling around the steel horse, he was sure that the skin and legs could be changed, because Ganfu had changed them, and the skin had to be changed.

The ready-made dragon scale armor piece is actually quite good, majestic, and can allow a wide range of movements, and the defense is not weakened.

Huo Guang also wants to consider lightweight, but according to his previous experience in riding a steel war horse, its performance is high and it should not change too much in a short period of time, which is enough.

So he was ready to devote most of his energy to the modification of his legs.

Huo Guang drew it with black charcoal on the ground, and Qiu Xiang watched from the side.

I saw that Huo Guang drew the horse and drew a wheel under the horse's legs, intending to turn the movement of the horse's legs into a connecting rod to link the wheel, so that riding a horse is like driving a car.

Qiu Xiang asked curiously, "Childe, why do you want to bring wheels?" ”

"Wouldn't it be more comfortable to sit on a horse like this, it's too hard to ride a steel warhorse."

Qiu Xiang said suspiciously: "Doesn't Childe feel that riding in a carriage is more uncomfortable than riding a horse?" ”

"Why do you say that?"

"When I was young, my father took me to the pasture, and I could ride a horse, although I learned for a long time, but after learning it, I could adapt to horseback riding, but many times I had to follow my mother in a carriage, and it was very bumpy, and I couldn't adapt to it."

Huo Guang patted his head and suddenly realized that the roads in this era are not good, and the wheels have no tires, so the unevenness and discomfort of the road will be very directly transmitted to the car.

In the city, the road is relatively flat, and it is not a big problem, but the road outside the city is difficult to determine.

The plan was directly rejected and the revision began.

Since he couldn't add wheels to his legs, Huo Guang thought of another possibility.

The suspension system of the car.

You can't copy it all, but at least the shock absorption should work.

The most critical part of the shock absorber is the spring, which needs spring steel, and the iron itself is not so elastic.

Excluding trace elements, pig iron and wrought iron are usually separated according to the carbon content, the carbon content of pig iron is greater than two percent, and the carbon content of wrought iron is less than 0.05%, and in between we usually call it steel.

Huo Guang and the iron refined by using Qi are almost composed of pure iron elements, all of which are wrought iron.

It is difficult to grasp the quality of quenching only by the last step of quenching, so the iron sheet of the steel horse is so easy to tear, the carbon content is too small, and the strength is not enough.

The texture of wrought iron is softer and the strength is not high, although the strength of pig iron is high, but the brittleness is too large, so the steel of the intermediate value is the best, and various alloy steels have different uses, and the best spring is spring steel is one of the alloy steels.

Now the smelting process of the Han Dynasty is not high, although the scholar can control things, but Huo Guang has not tried to directly control a single element.

If you haven't tried it, give it a try, Huo Guang asked Qiu Xiang to bring some coal, which also has carbon in it.

Huo Guang had specially learned about carbon before, because he was very curious about this element, it has a lot of magical allotropes, hard diamonds, soft graphite, magical graphene, the same element can appear in so many different forms of expression, it is indeed very magical.

Huo Guang wrote the word carbon, and with a wave of one hand, the Qi flow surged, and with the Qi flow, the carbon element was stripped from the coal.

"Yes." Huo Guang's face was overjoyed, he didn't expect the first attempt to be so smooth.

With the addition of carbon, the two were mixed, and Huo Guang carefully controlled it.

In the past, it was said that all the steel refining was constantly reducing the carbon content in the iron, but he didn't expect that Huo Guang would have to turn it over and increase it now, and he didn't know what would happen next.

When the two were mixed and finally cooled with water, the sound of a bang on the ground sounded, and Huo Guang eagerly came to his refining steel.

But Huo Guang did not have a standard for identifying the properties of this steel, so he just took it left and right, and thought that it should be a success.

Simply refining springs directly.

Because it can be shaped at will with molten iron, the spring is quickly formed after adding carbon, and the spring refined this time is larger to allow him to better test the performance.

After feeling the spring, its toughness and hardness can meet the use standard, Huo Guang began to think about modification.

In order to improve comfort, Huo Guang installed a small spring on the horse's shoe, and then added a horseshoe at the bottom to reduce the impact of the horse itself and the ground, and at the same time cushion it can also reduce the wear and damage to the horse itself.

In addition, a slightly larger spring is mounted under the saddle to act as a cushion.

The horse itself is too precious to Huo Guang now, so Huo Guang didn't dare to try drastically, he thought of another way, modify the carriage, and the carriage behind him can always operate it himself.

Finally, the family coachman can come in handy.

"Qiu Xiang, call the coachman at home."

The coachman Zhang Tie came back soon, and now Huo Fu doesn't even have a car, he, the coachman, is very idle, it's just a cleaning job, and he has to pay him an extra penny, it's really cool and crooked, but Huo Zhongru just doesn't agree to dismiss him, how can a big family not have a driver.

"Childe, what can I do?"

"I'm going to buy a carriage, and tomorrow you can take me to the car dealership."

As soon as he heard that he was alive, Zhang Tie immediately said happily: "Childe, you have to buy a horse before buying a car, there is no horse, and you don't know the size and strength of the horse to buy a car, it is easy to mismatch." ”

Huo Guang pointed to the steel horse: "Who said that we don't have horses." ”

The horseman Zhang Tie looked at the steel horse in surprise: "Childe, do you mean to use it to pull the cart?" ”

"Why not?"

"It's okay, but I haven't called this thing, I don't know how to use it, and besides, others have a steel horse that they ride on the street by themselves, and there are few people who use it to pull the cart."

"Don't talk nonsense, just use it to pull the cart, take me to choose the carriage tomorrow, can it work."

"That's naturally possible, don't worry, childe, I will definitely bargain for you."

Huo Guang was also a little tired today, he lay down on the rocking chair, fell asleep unconsciously, and woke up again with Huo Zhongru carrying him back to the room.

"You're awake, wait a while, go to bed and fall asleep, you young man, Qiu Xiang can't carry you, and I have to carry you, don't sleep outside in the future, you will catch a cold."

Unable to see Huo Zhongru's expression, he said abruptly: "Ah Guang, how do you know the symbol of the Bronze Empire." ”

"What is the Bronze Empire?"

"It's the pattern you carved on horseback."

Huo Guang had nothing to do before, and carved the pattern of Sanxingdui's golden mask on horseback.

"Father, do you recognize?"

"I don't know, I don't know, I've heard someone mention it, and I erased it for you when I looked strange."

"Oh, it's okay, it's useless."
