Ding Kui had no plans to build a magic tower, so he didn't go to the Magic Guild to check the information about the "magic mud".

After listening to the three beauties explain babblingly, he finally knew, "That is, clay with magic is different, and clay without magic is everywhere." ”

This time, even the recipe for studying limestone and gypsum was saved, and the Magic Guild had already mastered it.

"That's easy, all that's left is the calcination process. ”

Li Fei raised her eyebrows and said, "The Cai Ran you said seems to have come to Giant Sheep City recently." "She sometimes helps her brother with the affairs of the Magic Guild.

"So coincidentally?" Ding Kui was surprised, "He is my friend, no matter how busy he is, he has to see each other." ”

Li Fei put down the dishes and chopsticks, stood up, and said, "I'll go and invite him over, don't stop me, this is doing things for the people." ”

The truth is in front, Ding Kui is embarrassed to be polite to her, and he can't say that he knows fire magic.

"Is cement stronger than wall bricks?"

With magic mud as a reference, Huang Wan probably knows the properties of cement.

Ding Kui explained: "It is not enough to use cement alone, but also fine sand, gravel and steel bars, so I will call a few construction craftsmen to come over in the afternoon, and I will tell you the principle, and in the future, I will rely on you to experiment and research, and you will definitely be able to build a solid bridge." ”

He can't explain the concept of concrete now, and it is convenient to demonstrate it after he has the real thing, which involves a lot of physical and chemical knowledge. In his previous life, he had taken professional classes and also spent time on the construction site for internships, so he had enough knowledge to teach the craftsmen of the Shenyuan world.

"In fact, it is not bad to take soil and burn bricks, but it is very damaging to the environment, and it can only be used to a limited extent. ”

Huang Wan and Ruan Xingzhu completely became listeners, and they didn't know what Ding Kui was talking about, but it was definitely useful.

Ding Kui's expression suddenly moved, and he stood up and walked out.

"His mental power is so terrifying, has it been like this since he was a child?" Huang Wan secretly asked Ruan Xingzhu next to him.

"Yes, I didn't think much of it before, but now that I think about it, he used his mental power in battle, so he was often able to defeat the strong with the weak. Ruan Xingzhu's eyes are full of stars, she is a little fan girl.

Outside the main hall, Cai Ran shouted from afar: "Brother Ding, I haven't seen you for a long time, this trip is really not in vain!"

"Hahaha, Brother Cai, come to my place and don't inform me, you should be punished! Come on, come on, the wine has been prepared, just wait for you to drink!" Ding Kui greeted him enthusiastically with open arms.

The two verbal brothers hugged each other tightly, excited as if they had been separated for many years.

"Don't get over it. Li Fei muttered as she passed by the two.

"Ahem, cough," Ding Kui coughed to hide his embarrassment, "It's not that Your Excellency Li Fei doesn't know that Brother Cai is here, and he is not well prepared, please forgive me." ”

"My question, how can I blame Brother Ding, mainly because I think you are on the front line, and it is already good to be able to meet. ”

The two walked into the main hall hand in hand.

Take a look at the four magicians present, who are all in the four major systems, and can understand the world in an all-round way.

"All the most beautiful magicians in the kingdom are here, and I'm so lucky today. "Cai Ran knows the magicians here.

"Senior Brother Cai has won the prize, don't pull me to make up the numbers. "Huang Wan is most familiar with Cai Ran from the capital.

"Huang is a sister is also very popular in the association, and there are more people who pursue you than a branch city guild. "Cai Ran is a person who is more idle, and he can't help but ridicule when he sees a beautiful woman.

Huang Wan was embarrassed and not very good at dealing with such a scene.

"Senior Brother Cai came to Giant Sheep City at this time, wouldn't he be here to wander around, could it be that he came to pursue Senior Sister Huang?" Li Fei stepped forward to resolve Huang Wan's embarrassment.

"No, no, no, I have self-knowledge, Senior Sister Huang doesn't look down on me. ”

Cai Ran wanted to sit next to Ding Kui, but there was Li Fei on the left and Ruan Xingzhu on the right, and neither of them had the intention of getting up and letting go, so they had to take a step back and sit on the seat on Li Fei's left.

Li Fei said again: "Are you wandering around the magic communication array, waiting for news?"

"Uh," Cai Ran didn't expect to be questioned as soon as he came in, and he couldn't think of a good reason to lie, "Actually, I really have something to do with Senior Sister Huang when I come here." ”

Huang Wan's face turned red again, and said, "You tell everyone clearly, why don't I know?"

Ding Kui picked up the wine jug, poured wine for Cai Ran personally, and said with a smile: "The people sitting here are all my good friends, Brother Cai can see that we might as well have something to say, so that I won't be afraid to ask you for help if I have something." ”

"Okay!" Cai Ran raised his glass and drank it all, "Brother Ding is refreshing enough, I'm welcome." I heard that Senior Sister Huang is making some railroad tracks here, and Senior Sister Ruan is studying the wind array, all for the benefit of the people.

The teacher felt that we should not be left behind for the benefit of the people, and Brother Ding had saved my life, so he asked me to come over and have a look, and if there was a place that could help, I could help, and if there were not enough people, I could find more brothers and sisters. ”

The three beautiful magicians quickly glanced at each other, and Huang Wan said, "You guys are following my senior brother! You got the news so quickly, don't you also want to come to Giant Sheep City to get a piece of the pie?" Hmph, it's a pity that we don't need fire magicians. ”

"Yo, Vice President Kuai has a lot of resources, isn't it enough for your junior brothers?" Ruan Xingzhu was more direct.

Cai Ran and Ming Tang's teachers, like Rong Ci, are both vice presidents of the Magic Association, their names are Kuai Lian, and they are fire elemental magicians.

"Senior Sister Ruan's words are wrong, the family teacher has to take care of the fire magicians in the country, but it is not only our senior brothers, if you want to say that it is enough, how can we compare to you. The master wanted to build a magic tower and still hasn't started to build it, so how can there be any resources. ”

Cai Ran must maintain the reputation of the teacher.

"Besides, I'm here to help, if Brother Ding can use it, please just ask, Cai is willing to do something for the people. ”

He said it beautifully, but Sima Zhao's heart was well known to passers-by, and I have to say that Vice President Kuai had a keen sense of smell and insight into the business opportunities in Juyang City, and he came to the Railway Bureau.

Ding Kui used his gaze to stop Ruan Xingzhu from speaking, and hurriedly said, "Brother Cai is outside, I really have something to ask you for help." ”

"Really?" Cai Ran was overjoyed, this time he came to Giant Sheep City with the mentality of giving it a try, fire magic is really of little use to the people except for fighting.

"I just had an idea, I want to produce a material, there is a high-temperature calcination process in the middle, is there a way to maintain a high temperature?"

There is no such thing as a precise mark of temperature in this world, and craftsmen basically rely on experience to judge the temperature of fire, and it is impossible to measure it accurately.

Cai Ran asked, "What materials do you want to burn?"

Li Fei replied instead of Ding Kui: "The material similar to magic mud is the ash of mixed mud. ”

Cai Ran was stunned for a moment and said, "This is very simple, you just need to build a fire ash kiln, and I'll tell you the ratio of fuel." ”

"Isn't the fuel ratio a secret recipe?" Ding Kui didn't understand, and Tai Shugong's inheritance was not recorded.

"It may be a secret recipe for the people, but it is not for the magicians in your family. Cai Ran smiled bitterly.

Li Fei nodded and said, "Indeed, you will know when you go back and ask the teacher." ”

Ding Kui saw a look of disappointment flashing in Cai Ran's eyes, so he said: "Actually, all kinds of magicians are useful to the people, Brother Cai, don't worry, there is always a place for you." ”

"Maybe I don't believe what others say, but when it comes out of Brother Ding's mouth, I believe it!" Cai Ran regained his confidence.

The fire magicians of the Shaodian Kingdom are poor, and most of the fire resources in the country are in the Nine Lamps Mountain Range, which are basically all controlled by the Burning Heart Palace.

The most hateful thing is that the Burning Heart Palace also sent people out to plunder resources, and the Fire Mage Sect of the Shaodian Kingdom did not have the support of the Law God, so they couldn't fight the people of the Burning Heart Palace, and they couldn't grab many resources.

When Huang Wan greeted the senior brothers in the capital, she was noticed by Kuai Lian, and Cai Ran appeared in Juyang City.

It's a pity that I don't build a thermal power plant, otherwise it would have greatly increased the productivity of the plant.

Ding Kui is not omnipotent, his knowledge in his previous life is limited, and he cannot bring all the technology of the earth to the Shenyuan world.

He couldn't even build a steam locomotive, otherwise he wouldn't have used a wind-powered railcar.

"Is there a way to store the heat from incineration?" he asked, asking a question he hadn't figured out.

When Hengfu City was besieged, he thought about burning the city's garbage, and he also tried to burn some of it, but he didn't continue because the smell was too strong.

Cai Ran replied without thinking about it: "Boil water to keep warm." ”

Plumbing!

Ding Kui thought of something else, but he couldn't make a water pipe before.

"Forget it, let's talk about it later. He gave up first.

In the afternoon, I really found a few construction craftsmen, Ding Kui and Cai Ran explained the firing method of cement together, and the craftsmen thought they could try it.

The people of the Ding family were very efficient, and they quickly found the raw materials for burning cement, and Cai Ran directly urged the fire magic to burn the cement clinker.

Ding Kui had people nail out a formwork, then hand out the concrete and pour it into the formwork.

"Tomorrow morning, this is a cement slab, very strong, if it is a little bigger, you can build a steel skeleton first. He instructed the craftsmen.

One of the craftsmen asked, "What is the rebar?"

"Your Excellency Huang Wan. Ding Kui found Huang Wan, gestured with words and hands and feet, and told her how to make steel bars.

Half an hour later, Huang Wan used iron ore to pull out a few steel bars.

"Oh, this thing can be made by a blacksmith, but it's a lot of work. "The craftsmen got it.

Ding Kui pulled Huang Wan to a corner of the outer courtyard, pointed to the ground, and said, "Dig a hole twenty meters deep, it's so big." "Two hands against each other.

The earth magician digging a hole is called fast, Huang Wan turned the magic wand, and in less than a minute, a twenty-meter-deep hole was created.

"Build an iron cylinder and insert it, the wall of the cylinder is about the same thickness as the bucket, more than 20 meters, a little higher than the ground. Ding Kui continued to point.

"Are you going to bury the foundation?" said one of the craftsmen.

"That's right!"

"Do you want to build a castle? The craftsman was a little smug.

"Definitely. Ding Kui nodded, "Giant Sheep City has no city walls, and my lord's mansion needs to be built into a castle, which can accommodate at least five thousand people to fight." ”
