"Sure enough, it's oil, it's okay!" carefully looked at the black liquid in the barrel, dipped some of his fingers in front of his nose and smelled it, and after confirming that it was correct, Jia Zhengjin immediately put them all away.

"Is this what you want?" said Sengil as he looked at his excitement from the side, blinking, "Then can we talk about the specifics of ordering this mineral from the dwarves?"

"Don't worry, we'll talk about it later!" Jia Zhengjin said with a smile, "I'll see if there are any new materials in hand during this time." ”

"Who just said that you should finish things early and then go to rest?" Facing Jia Zhengjin, who suddenly came to the spirit, Xian Jier was very depressed.

Jia Zhengjin smiled embarrassedly, but still picked up the warehouse ledger recorded by Nancy and flipped through it carefully: "Hmm~ Not bad! It's really clear at a glance...... Hey, there's so much hoarding of gold and silver?"

"Yes, Master Keane!," replied Nancy hastily, "for the past month, Mrs. Perrin has sent troops to the field mines at intervals to bring back the minerals there, as you have told you. At the same time, the number of kobolds, miners and warriors is constantly replenished. Ordinary ore is smelted in factories and processed into weapons and armor by kobold artisans, while some is also processed into agricultural tools to supply the city's needs. It's just a pity that no more precious ore than gold and silver has been dug up!"

"It's normal for the veins over there to be so shallow!" Jia Zhengjin shrugged his shoulders and said, "As expected, box 77?

"Yes!" Nancy immediately nodded in response.

"Oh yo! There are thousands of slime slimes stored in it?" On the list, Jia Zhengjin saw another good thing.

"According to your instructions, the patrol found a small group of slimes near the city, and this month they have captured about half of them, and they have collected enough slime!" Nancy replied, "The other half of the slimes were left behind so that they could continue to reproduce as they were for us to capture again in the future." ”

"Hmm~ very good! I took the slime too!" Jia Zhengjin checked carefully and confirmed that there was nothing else that could be used, so he put down the ledger and took away all the gold, silver and slime slime placed in the wooden box, and took a large number of strange cloths along the way.

"Lord Keane, can we talk about ordering oil now?" asked Sengil, looking at him as he came out of the warehouse. After all, if you have to get up early tomorrow to go back to the Elven Forest, you must hurry up and negotiate, and then go home with peace of mind.

Jia Zhengjin turned his head to look at her, and couldn't help but smile: "Let's talk while walking!"

General Isha and the elven girls immediately followed, and walked to the other side with Jia Zhengjin and Xianjier.

On the way, Xian Jier bargained with Jia Zhengjin about the price of the oil.

Although she claimed that the Holy Dragon City was a good friend of the elves, it was clear that the friendship was still deeper than that of the dwarves, so she tried to raise the price.

Jia Zhengjin said that there should be no second person who needs this kind of oil except himself. If you don't buy it yourself, oil is waste to the dwarves and has no value at all. Take advantage of this to press down desperately.

The two argued as they walked, and finally reached a consensus. Jia Zhengjin ordered oil from the dwarves at the price of 1 silver coin per catty, which was 20 gold coins a ton. A minimum order of 100 tons of oil is required, which is 2,000 gold coins.

In modern times, that's really nothing. But in another world, without any oil extraction tools, 100 tons is also quite a difficult task for dwarves.

And 2,000 gold coins is also a good income for the dwarves, so Xian Jier naturally helped them agree. What makes Jia Zhengjin feel that the elves are very cute is that as intermediaries, they don't want anything in return, saving Jia Zhengjin a sum of money, although he doesn't really care about it now.

During the conversation, he came to the resource exchange and decisively exchanged all the gold and silver mines for gold coins.

After a month's accumulation, all the gold and silver mines together sold more than 4 million gold coins. This is also something that can only be done after the quality of mining tools has been improved to a certain level. In the beginning, the output of gold and silver mines was pitifully low!

However, 4 million is still a drop in the bucket for the current Jia Zhengjin. After all, now that the population of Holy Dragon City is becoming more and more dense, he has to raise more and more troops under his command! Sure enough, he still needs to rely on the auction house!

"Now that we've negotiated, give me the first batch of deposits!" said to Jia Zhengjin from the side, "When we go back tomorrow, I'll help you contact the dwarves." ”

"Don't worry! Jia Zhengjin took the elves all the way to the alchemy laboratory and asked them to wait outside. He quickly went inside and began to convert oil into gasoline.

It takes about half an hour for 10 barrels of oil to be fully converted. Jia Zhengjin couldn't wait that long, so he came out 10 minutes later, bringing a considerable amount of finished gasoline.

Anyway, it's enough, let him produce the rest automatically, and get it when the time is up!

"What the hell are you going to let us see?" Agell looked helpless, "We really have to get up early tomorrow, can we give the deposit first, and we have to go home as soon as possible after a good night's rest." ”

Jia Zhengjin was also in a hurry to rest, but he was full of energy at this time. The main thing is that I am too excited, because I can finally make the motorcycle work!

Moreover, if you have gasoline, you can make your new transport truck! How can you build several cars after hoarding materials for a month? If you can see the cars running on the road, it will be very impressive!

But there is a question, what will happen to the driver after the transport truck is built? People from the other world shouldn't be able to drive it, right? Will they have to train themselves one by one?

But if you want to see modern streets, this is also an effort that must be made, right?

When he took out the motorcycle, under the curious eyes of the elves, Jia Zhengjin excitedly filled the fuel tank and couldn't wait to ride it.

"What is this for?" General Isa asked curiously.

"Don't you know if you see it?" Jia Zhengjin started the engine, and the motorcycle immediately let out a loud roar, and at the same time, thick smoke sprayed from the rear.

The elves were startled and quickly dispersed to the side.

"What kind of monster is this? Is it angry?" said Signier, looking at Jia Zhengjin worriedly.

"I seem to be really angry, and it's still spewing smoke!Could it be some kind of fire-based monster? But I've never seen one!" Isha looked at the motorcycle warily, "Keane-sama, this monster looks like it's going berserk, is it okay?"
