Chu ran back to Xiang's mansion with pity and found that Xiang Bei was drawing. When I came back, I just raised my head.

Chu asked Xia Hua who was waiting next to him: "What is this guy painting?"

"The gentleman said that he would install the heating in the house, so that he would not have to wear so thick in the house. At this time, the installation diagram was drawn, and I didn't understand what it meant. ”

After Xia Hua finished speaking, Xiang Bei raised his head: "Originally, I wanted to make an iron box as a warmer, which is connected to the flue, so it's very simple." But come to think of it, such a stove can only be used to heat two rooms, not to mention that there are children at home who are afraid of burns, so they simply take one step and make plumbing. In this way, the stove is placed in the firewood room, and the radiator is connected to our guest bedroom, so that it can be warmed. ”

"You say you use water for heating? It's a novelty, in the Wind Tunnel Valley you used snow to keep warm, and now you have to use water to keep warm. ”

"To be exact, it's the circulation of hot water to keep warm, there are no radiators in this world, but it doesn't matter, there are refiners, and I can make radiators out of ordinary steel pipes. The water flows in the radiator, and the hot water in the furnace flows into the radiator, and the cold water in the radiator is squeezed into the furnace to heat it and then flow in, forming a circulating system. ”

"Steel pipes?"

"You call it empty round steel, and the world doesn't use it much, but there are still some of them. It's just that if there is no iron, the blacksmith can't do it, and it's all for the refiner's special use, and the refiner's materials often don't use pure iron. ”

"Yes, the refiner doesn't bother to refine ordinary steel, who will do this for you?"

"Those who are just getting started, let them come. This thing is not a magic weapon, and pure iron is also easy to refine, so you can get it at the entry level, and it's cheap. Even if you get a master, the cost is too big. ”

Chu took a closer look: "On your picture, the steel pipes are connected into these grids, which is the so-called flowing radiator, right?"

"That's right. ”

"Then how to ensure that the connection is not leaked, a beginner refiner, it is good to be able to train you into a steel pipe, it is impossible to connect you into such a complex water flow channel. ”

"It's okay, as a level 7 welder. It's rudimentary, but I have a way to connect him. ”

"Then your vertical pipe mouth is connected to the curved surface of the horizontal pipe, and it can't be tightened. ”

"As a senior plumber, I can make horseshoe mouths at both ends of the vertical pipe, that is, the plane is concave, just stuck in the horizontal pipe, to ensure that it is placed tightly, as long as the pipe specifications are the same, I can estimate the cutting situation with my eyes, and I don't even need to bring in the formula. If it really doesn't work, you can also plug in and weld in a different diameter, that is, the vertical pipe is thinner, and the horizontal pipe is directly inserted into it. ”

"I don't understand. ”

"Then just wait to use it, you can help me find a dagger that sharpens iron like clay, and I will cut the material." ”

"Ghost, where to find it, the so-called sharpening iron is like mud, that is the blessing of the warrior with his own strength. No matter how good a dagger you are, you won't be able to sharpen iron like clay. ”

"Then let the four great guards help me. ”

"What's on this side?"

"Stove, by the way, you go and find some iron sheets for me, and I'll make the stove. There is also volcanic sand and volcanic mud to make fire-resistant liners. ”

"And what is the tallest thing up here, what do you need? Do you want me to find it for you?"

"It's a bucket of water, and it's placed in a high place so that it doesn't overflow. It's okay to make it with iron sheets, it's not just casually installed, there is no circulating pump, and it can't be heated up if it's wrong. ”

"Okay, what are some expectations, how many days will it take?"

"Two days, it's too restrictive. ”

"I'll help you find someone to make steel pipes, you get this lattice first, and then I'll go find the iron sheets. ”

"Okay, but to emphasize, it's called a radiator, not a lattice. ”

Chu Pian excitedly ran away with the four guards, Xiang Bei put down his pen: "Haha, it's good to have someone to help run errands." ”

Xia Hua rolled her eyes: "That's the princess." ”

"What's wrong with the princess, curiosity kills the cat, as long as she has curiosity, then she has to work hard. I'm going to prepare something to weld, Mom's, there's no welding consumables here, the heat must be controlled, otherwise it's strange if it doesn't leak. ”

Xiang Bei also left home, how to weld he has a preliminary idea, but he has to buy something to try first, this matter Chu pity can't be done. Fortunately, there is no pressure on the heating, otherwise he really wouldn't dare to say that he can guarantee that it will not leak.

In this way, a group of people began to work hard to make heating, although there are not so advanced tools in this world, but fortunately, there are many superpeople. The blanking depends on the knife used by the warrior, and the iron sheet does not need a folding machine. If there are no pipe fittings, they are all welded together.

So the only trouble is welding, he doesn't have a welding machine, but he knows that there is a good thing in this world, the heart stone. It is used by the fire mage for cultivation.

When the fire stone is smashed, it is a red, viscous liquid inside. These liquids ignite and melt steel. Xiang Bei named him hot melt paste, inspired by the hot melter used by plumbers at home. This thing is also used by alchemists.

The Flame Heart Stone is very expensive, or the things used by mages are expensive, especially this kind of thing that can assist in cultivation. It is certainly impossible for the blacksmith to be able to afford to do his work, but he is only applying the solder joints partially, and he is still willing to use a small amount.

In this way, after the thing is bought, the blanking is calculated, and the welding is installed. He smeared the hot melt paste on the weld, then took the fine iron with the other hand, and also smeared the hot melt paste, and then lit it together, the hot melt paste became red, and then the fine iron was melted, and the molten iron pool was also melted at the bottom of the weld, and the molten iron was melted into it by argon arc welding, and it was done. Although it looks simple, he has tried dozens of times, because once the hot melt paste is smeared too much, it will become a big hole, and once it is smeared less, it will not melt together at all. This is his exclusive technique. After getting it done, I found that it was more beautiful than an electric welding machine, and the welding bead was comparable to an automatic welding machine.

A large group of people, even the martial artist and Chu took pity on the help of this Yuan mage, and it took two days of busy work to get it done. And there are so many rooms, only the most important rooms in the front row are installed, and the radiators are really troublesome, and there are too many installations, so you have to use a large boiler.

After making it, add water to check the leakage point, and after making sure that there is no leakage, light the fire in the furnace.

The white smoke was steaming from the chimney, and Chu ran over to touch the radiator with pity: "Why isn't it hot?"

Xiang Bei couldn't stand it: "The water is not hot, why are you in a hurry." Add fuel to the fire, don't worry about exploding, I have left the exhaust pipe. Professional plumbers, we're not bragging. ”

It burned for half an hour, and finally the house heated up. Xiao Lili and Chu Pian were excited to try it next to each other in several rooms, and after making sure that it was all hot, the two of them ran back with an excited face.

Chu pityfully raised his thumbs: "Old Xiang, you are so handsome, a stove can warm up so many rooms." Now as long as we hire a stove, we don't need to get up and add fire at night. Princess Ben decided to come to live with you. ”

Xiang Bei asked them not to make a fuss and be trivial.

Chu took off his cotton clothes directly and stretched his body: "It's so comfortable, Lao Xiang, you are reliable, I am more and more confident in the things you want to run a factory." ”

Xiao Lili raised his hand: "Master Princess, can you let my parents be in charge of burning the stove." My restaurant doesn't make any money at all. ”

Xiang Bei said no, his restaurant is not usually full of people, why don't you make money.

Little Grain shook her head, she didn't understand why. only said that he went home the day before yesterday and saw that his parents were almost beaten because they couldn't pay taxes, so he must be not making money.

Chu pity's face was cold: "Xia Hua, you went back with Xiao Li, what the hell is going on? Who dares to beat Xiao Li's parents?"

Xia Hua hurriedly stepped forward: "Back to the princess, here's the thing." ”

Xia Hua talked about the matter of Anmin tax, and after finishing speaking, she told the princess that she didn't say it, but everyone was too busy in the past two days and forgot about it.

Chu nodded with pity, and did not reprimand her, but asked Xiang Bei: "Now that Yunlang is going to be the commander of the Red Leaf City City Guard, should we also do something?" ”

Xiang Bei said that this city lord is now caught, and it can be used by them. In addition, it's not that there is no deputy commander, so just install another deputy commander. Let that Yunlang do it over there by himself, not staring at him at all, it is indeed a little uneasy.

"Let's go together" Chu told Xia Hua with pity: "Send a message to the city lord of Red Leaf City, and come here to see me tomorrow afternoon." In addition, I informed Xiao Lili's parents to come to Xiang's house to cook for us, I guess he doesn't make money because the house is rented. ”

Xiao Lili said that their family was not in the city, but from Shiliqiao Village outside the city. At the same time, thank you to the princess for giving her parents a new job.
