Over the next month, Jia Zhengjin expanded the factory underground more than ten times, placed a large number of production lines at the same time, and recruited thousands of kobold craftsmen to work in shifts day and night to produce parts and assemble air conditioners.

Although it is still a long time to allow all the people of the entire Holy Dragon City to use air conditioning, at least the close family members, the ministers of civil and military affairs, the buildings that entertain foreign envoys, and then important facilities such as magic schools, churches, and various factories are already air-conditioned.

During the day, ordinary people can also go to public places to rest and blow cold winds to dispel the heat.

As a result, schools, churches, shops, and even factories are almost overcrowded.

The factory produces a large number of air conditioners every day, and Jia Zhengjin also sends people to continue to distribute them, and the people who apply for the installation of air conditioners have already completed the formalities, and the fees that should be paid are also paid in advance, so they are looking forward to entering the house coolly.

At this rate, at least one-third of the city's homes will be air-conditioned by the end of the next month.

Jia Zhengjin is also preparing to expand the factory again and add more production lines, in order to make every household have air conditioning faster and more comfortable to spend this hot summer.

There are so many merchants and envoys who come and go to the Holy Dragon City every day, and of course the air conditioner immediately caused a sensation as soon as it appeared.

Needless to say, many emissaries wanted to be able to get air conditioners and bring them back to their home countries.

Merchants are enthusiastically bidding, hoping to purchase and wholesale air conditioners, because this is an absolute business opportunity, and the nobles and wealthy businessmen of the mainland countries are willing to get it no matter how much money they spend. This is cheaper than the cooling magic array!

No, even the elven king Noel came to the door in person.

From time to time, this thing goes to the Holy Dragon City to live for a period of time, and completely regards this place as his home. A few days after I went back to the Elven Forest, I probably heard about the air conditioner, and hurriedly teleported over.

It turned out that he had asked Jia Zhengjin to set up a teleportation magic array in the Elven Forest before, and it became very convenient for the two sides to come and go. Now the Elves can be seen everywhere in the Holy Dragon City, and there are often officials and people from the Holy Dragon City who used to play and work in the Elven Forest.

"Hurry up and give me a batch of air conditioners, the price you say. When he came to the palace, he shouted at Jia Zhengjin without sitting still, "Hurry up, and the generator set is also needed." That one...... I also need a batch of street lights, so it's best to help me design them in the shape of trees. ”

"Surprise me!" Jia Zhengjin was studying the city plan map, and suddenly heard his voice, and looked up, "You're here, why didn't the guards inform me?"

"It's all so familiar, what else do you want to inform?" Noel came directly to Jia Zhengjin and sat next to him, "Hurry up, get a batch of air conditioners for me." There's such a good thing, you don't want to get me some, if the clan didn't come back and report it to me, I'd still be in the dark!"

"What kind of air conditioner do you want in the Elven Forest?" Jia Zhengjin frowned slightly, "That large forest is a natural thermal insulation layer. Plus there's water everywhere, it's different from ours, right?"

"It's a little better than yours at most, but it's hot!" Noel urged, "hurry up, get me some." No more, two or three hundred units are enough!"

"Two or three hundred?" Jia Zhengjin shook his head and stood up, "There are none." According to my plan, in the next two months, every household in Shenglong City will be able to use air conditioning, and then I will consider exporting. ”

Noel was not happy when he heard this: "Isn't it? What do we have to do with each other, are allies who live and die together! I don't want you to have two or three hundred air conditioners? I don't want you to take you for nothing, you quote a price and I will buy it." Don't make a fuss, get ready for me. ”

"Really not!" Jia Zhengjin spread his hands, "Otherwise, in two months, the first batch of air conditioners produced will be given to you first." ”

"Two months, too long!" Noel was rather displeased, "you can move me out of the first batch." Didn't a large number of air conditioners be installed in Shenglong City? I have personally checked and found that the vast majority of the people have a place to cool off, and the impact is not great. I've come here in person, don't you give me this face?"

"Well...... this"

"Seriously, prepare a batch for me. I had already dropped my words to my family before I came. Noel said depressedly, "I can promise them that with our friendship you will definitely prepare for me." This face, you have to give me this face, right? Big deal, give you more spring of life!"

Jia Zhengjin is not interested in the Fountain of Life now, because he owns the Tree of Life and does not produce it every day. If you think about it carefully, Noel has come over in person as the elf king, and the relationship between the two parties is really good, so it is not appropriate to refuse like this.

After thinking about it, he finally nodded: "That's it! I'll get a hundred units from the plan first, and any more will have too much impact." Besides, I don't want the fountain of life, you get me ore or just pay for it with gold. ”

"A hundred?" Noel thought for a moment, "less is less...... So, give me 100 units this month, and get me another 100 units next month! And then every month, you will buy this quantity. ”

"One hundred units a month?" Jia Zhengjin hesitated.

"You wouldn't disagree with this little thing, would you?

"Okay, okay!" Jia Zhengjin had no choice but to nod in agreement, "Then be it!"

Really, Noel has lived for thousands of years, and he is a brother to me, who is only sixteen years old......

"Since you can get a hundred units a month, why don't you get a few more?" "How about a hundred and fifteen?" Noel asked again with a wink when he saw that he agreed.

"You don't have to make an inch!" Jia Zhengjin was suddenly unhappy, "A hundred units a month will affect my plan." If you really want to blow the air conditioner, isn't it different for you elves to teleport over and rest in the public areas of my city? And it's free!"

"Although we want to be nice to each other, your city is now a mixture of dragons and snakes. Not to mention the envoys, tourists, and merchants from various countries on the mainland, even those mercenaries of different qualities, all kinds of people. Noel shook his head and said, "Let's have the elves deal with these people, that's not okay. ”

"Anyway, 100 units a month, before my own planning in the city is completed, it is already an extra exception, and others don't have this opportunity!

"Okay, okay, I don't embarrass you! 100 units is 100 units, what do you say about the price?"

"With our relationship, can I still kill you?" Jia Zhengjin thought for a while, "Of course, I can't give it to you for nothing, just double the cost price!"

"Isn't this killing me?" Noel was displeased, "twice the cost price, are you kidding?"

"Who is kidding you? Let me tell you, when the plan is completed and officially sold to the outside world, I will set the price at least twenty or thirty times the cost, and maybe even hundreds of times. ”

"So dark?"

"What's black? Even if it's really a hundred times the cost price, it's still very cheap compared to that kind of cooling magic array. I don't believe you look at it, no matter how high the price is, I will be robbed like crazy. ”

"Hiss~" Noel lowered his head and thought for a moment, "This business is good, so can I buy from you at a low price and sell it at a high price?"

“......”
