Liang Zi asked He Xu to tell him about the idea of his orbit, why not use wheels, but iron balls?

He Xu took out two pictures to tell them that the main reason is that the passage is too low, so the lower the rail car itself, the better. In this way, the iron ball is used as a wheel, and the track and car are added, and the total is only one slap high.

In addition, it is smooth, there is no bearing is resolutely not to use the wheel, there is an axle with the wheel, do fine without grinding, do rough not smooth, there must be a bearing, otherwise the light maintenance is also tired.

And the most critical thing, a rail car with wheels at least four wheels, the car may be longer, there are many curves in the passage, the car body is hard, there is no way to turn, it is easy to derail, and if you don't derail, you will get stuck. The iron ball can be made shorter to ensure that every bend can be turned, and then the car is connected, and the iron chain is connected to the section to turn. Straight doesn't work.

Liang Zi said that it made sense, it was like that, and asked him if there was such a car in his hometown?

"No, I did it according to local conditions, and my hometown doesn't do tracks in this kind of terrain, so it's better to make a slide directly. There is no point in doing tracks. ”

He Xu put the picture away and asked her when her brother would arrive?

"It won't take two days, and then I'll be gone. There is a purple gas hall in this Baiyun City, which is a low-level shop on our Purple Light Island, I will take you to meet the boss, and when the time comes, what you need to buy, just look for him. including food, and you can ask him to buy it for you. No problem. ”

Shui Yiyi thanked her, thank her very much, at this time, those people in Ping'an Country need trade channels the most. Otherwise, even if they have money, it will be difficult for them to buy things, because at this time, I am afraid that all countries are curious about where they are going, and they will definitely monitor the grain merchants.

As they spoke, they also came to a purple qi hall, and after entering the hall, it was overcrowded.

Why do you want to ask a few questions, is their business so good?

Liang Zi said no, the main reason is that the Shengguang Gate has a registration office here, and when the registration is completed, many people will follow Xiaofu and them directly and go to Shengguang Mountain to prepare in advance. Because there are very few registration offices, some of these people come from far away, and they go back and forth for a few days, which is not worth it, so it is better to go directly to Shengguang Mountain.

And at this time, it is also a time when robbers and bandits are active, Shengguang Mountain does not belong to any country, and there is no official road to the nearest road there, so it is not safe to walk alone, so it is better to follow everyone. In addition, after going, you can contact some disciples of Shengguang Mountain in advance, which will also help you with the assessment.

And Ziqitang's business is so good, because everyone is in a hurry to buy some mysterious utensils and keep them for assessment. The quality of the things produced by Ziguang Island is guaranteed.

He Xu looked back: "There is also a Chengqi Hall opposite, isn't this from Tianchang Wangcheng, their business is also so big, even here?"

Liang Zi said that of course Chengqitang can't be compared with Ziguang Island, Chengqitang is the boss is a senior artifact maker, there are only a few instrument rooms, how can they refine so many mysterious weapons, they are not mainly making utensils, they are selling, and tens of thousands of gold coins are purchased from Ziguang Island every year.

"Then they will open a store opposite you, isn't it a loss? Can he, a wholesaler and retailer, directly confront your manufacturer?"

Liang Zi shook his head: "I don't know, they have been here for many, many years." It stands to reason that we shouldn't, our store is here to facilitate trading with Boss Liu, otherwise we wouldn't have set up a store here. If we just sell something, we all lose. So what are they trying to do?"

Liang Zi couldn't figure it out.

Shui Yiyi looked at the people in the Purple Qi Hall and said, "It's so busy, let's not go in first, find a place to eat, etc., and come back in the evening." ”

Before Liang Zi could speak, suddenly a man next to them spoke: "A few of you haven't eaten yet, let's go to our store to eat." ”

"I'm going, the solicitors are all here, you really know how to do business, which restaurant? I won't go to the small restaurant. "Liang Zi is quite exquisite.

The man said that it was not a restaurant, but a Chengqi Hall in the back.

"You Chengqitang can't survive selling mystical wares, have you opened a restaurant?" Liang Zi was curious.

"That's not it, it's our shopkeeper's invite. "This is a fellow from Chengqitang.

Liang Zi looked puzzled, how could he say that he would know if he went to sit down, and there was nothing to do anyway.

The guy was happy: "Those guys, please." ”

The guy led them into the Chengqi Hall, and the business of the Chengqi Hall was not bad today, but it was not as hot as the Purple Qi Hall.

The man pushed open a door: "The shopkeeper is waiting inside, please come in." ”

The four of them walked in, and it was the shopkeeper when they were in the Heavenly Dragon King City. Seeing them, the shopkeeper said with a smile: "Young Master Ren, Young Madam, meet again." ”

He squatted down, told him not to make such jokes, and asked him why he came here?

"I'm waiting for you here. The shopkeeper looked mysterious.

How did he know he was coming here?

"Because this place is the closest to Bifeng Mountain. The shopkeeper looked happy, but Shui Yiyi's face was ugly: "What do you know?"

"I know where everyone in the Divine Sword King City went, when I was in the Tianchang King City, I knew that Gongzi He was not the sixth young master of the General's Mansion. If you run away, you will definitely go to Bifeng Mountain, and you will definitely appear in this nearest city, but I didn't expect you to come out so soon. The rivers and lakes are hunting for rewards, and you are not afraid at all. ”

There is no reason to ask him how he knows this. I can't figure out what went wrong.

The treasurer replied, "I am only a subordinate sent by others, and I naturally listen to the Lord." As for who the lord is, you can guess it and see if you can guess it. ”

Several people looked at He Xu together, and He Xu replied that it was the Black Crow God, everything in the Black Crow Forest could not get rid of the eyes of the Black Crow God, and only he knew that he had dug Ren Tianda's grave there. Ren Tianda, who knows that he is a fake. As for how he knew that the people of the Ping'an Kingdom had arrived at Bifeng Mountain, it was estimated that he had a friendship with the Divine Sword Martial Emperor. Know the teleportation secrets of Excalibur King's City.

The shopkeeper said yes, that's right, including the Divine Sword King City, including the Heavenly King City and the Underground King City. Such a mysterious city can only be done with the participation of thaumaturgists. The Black Crow God also participated at the request of the Divine Sword Martial Emperor back then. In the future, these will be of great use, and they are not reserved for the Heian royal family to hide. But Seikido took root here, and it was indeed to help Heian Province. Since they have gone to the dungeon, it must have been the death of the country, and it is inconvenient to do anything. Seikido can help or something.

As he spoke, he handed He Xu a jade pendant from the Chengqi Hall and told him that he could command any Chengqi Hall at will in the future. Moreover, this jade pendant itself is also a mysterious weapon, and in an emergency, it can be infused with Xuan power, which can be transmitted hundreds of zhang away.

He Xu said yes, this is great, I didn't expect such a good thing.

Liang Zi spread his hands: "It seems that Ping'an Guo doesn't need our Purple Qi Hall to help do anything, Chengqi Hall is already waiting." ”

How can I say that it is different, or their path on Ziguang Island is wide, of course, they still have to use it.

The shopkeeper asked Liang Zi, "The girl is the newly registered disciple of the Lord, right?"

Liang Zi said yes and asked what's wrong?

The shopkeeper replied, "I just received a message from the Lord, if I meet you, let me take you to the Black Crow Forest." ”

Liang Zi said that after two days, his brother would come and go.

"Well, I've completed my mission. Since Miss Liangzi's brother is coming, I don't need to wait for Miss Liangzi to leave together, so I'll say goodbye, and I'm quite busy going back. ”

The shopkeeper was about to leave. Why don't you ask a few meanings, didn't you say that you came to eat?

The shopkeeper stopped: "You really haven't eaten?"

Several people nodded together.

"Then eat first. The shopkeeper sat back and called in the man to ask the restaurant to deliver some food and drinks.
