At that time, Qin Xuan found that the goods in his hand were very sought-after, and he might sit on the ground and start the price.

The starting price of sitting on the ground is not at all, even if it is exchanged at a ratio of 1:50, Qin Xuan can still make a lot of money.

What's more, the ratio of inferior dragon crystal ore to high-purity dragon crystal has reached 7000:1, which is definitely an extremely exaggerated ratio.

Qin Xuan just mastered the "technological advantage" and used it to "squeeze" a few dragon maiden ladies, if Long Si knew how terrifying Qin Xuan's profit ratio was, she would have to strangle Qin Xuan on the spot.

The dragon clan's demand for high-purity dragon crystals is huge, and theoretically they can infinitely devour dragon crystals to evolve themselves.

But for them, there are more impurities in low-purity dragon crystal, and the taste is very poor, and they will get tired of eating too much.

The higher the purity of the dragon crystal, the higher the taste, the greater their appetite, and the more dragon crystal they consumed.

Moreover, the dragon clan in the sea is not only the dragon king, they are also a large group.

Even if the dragon clan's reproductive ability is relatively poor, it has accumulated in the wild world for tens of millions of years, and there are still hundreds of thousands of people.

If Qin Xuan can satisfy the "appetite" of these people, he will definitely make a lot of money.

Doing business is about integrity, and it is better not to change the price at will, and the price increase at two ends in three days will definitely cause the disgust of the dragon family.

High-purity Longjing ore is only "more delicious" for them, and it is not a necessity for survival, so the sky-high asking price is definitely not good.

There is a Crystal City near the Dragon Palace, the Crystal City is much larger than Qin Xuan's Snow Grain City, and the popularity inside is countless times stronger than the Snow Grain City, but in a certain aspect, the Snow Grain City is completely capable of crushing the Crystal City.

When Snowgrain City was just started, Qin Xuan hadn't gotten the technology ball yet, and the original building was still a civil structure in the Savage World.

But later, after Qin Xuan got the technology ball, he would definitely not engage in construction according to the old standards of the wild world.

The civil structures of the Savage World are short and ugly, which is completely inconsistent with Qin Xuan's aesthetic views of modern people.

And Qin Xuan's science and technology ball is engaged in a scientific research base model, and the current scientific and technological strength far exceeds the level of the earth in the 21st century.

After the database upgrade is completed, Qin Xuan's robot has the qualification of a senior construction engineer, and the construction of high-rise buildings is not a problem.

This makes Qin Xuan's Snow Grain City small in scale, but there are a lot of interesting places.

One of the 18-story buildings aroused the strong interest of Long Si and several of them.

"Your tall tower is a bit of a doorway!" Long Si climbed 18 flights of stairs to the roof in one breath, his face was not red or breathless, but he was full of praise for Qin Xuan's high-rise building.

In fact, this high-rise building is designed with an elevator, but the production of elevators requires a large number of supporting facilities, and robot workers are now in full swing construction, and may need to wait for a while before they can use the elevator.

For Long Si's praise, Qin Xuan smiled back tepidly: "Your Royal Highness Princess, you are too polite, this is just a little trick, not worth mentioning!"

"I want to stay with you for a while, okay?" Long Si looked very interested in Qin Xuan's high-rise building.

The crab general who followed next to him hurriedly reminded: "Fourth princess, let's return to the Dragon Palace as soon as possible, it's too dangerous here!"

"Smack!" Ryusi stretched out his hand and slapped General Crab in the face!

After slapping him, Long Si also coldly reprimanded: "You don't need to ask about the affairs of this princess, if you dare to talk more, I will kill you!"

"Yes, Your Highness Princess, I don't dare!"

After General Crab was taught a lesson, the eldest princess ran over to persuade her, "Fourth sister, don't be naughty, your father will be angry, we have opened our eyes in Snow Grain City, and we will return to the Dragon Palace tomorrow!"

"If you want to go back, you can go back by yourself!" Ryusi replied with a grimace at the eldest princess, "I don't want to go back to prison!"

"Look at the outside world, the sky is high and the sea is wide, and that place in the Dragon Palace is lifeless all day long, and it annoys people to death!"

The environment of the Dragon Palace is indeed very stuffy, and the underwater world is not able to transmit sound!

The prosperity of the outside world, what you can't hear when you stay under the water, you can only stay inside the Dragon Palace and communicate with other dragons.

It's so interesting like the outside world, the birds are singing and the flowers are fragrant, and you can stand on a tall building to blow the wind without having to soak in the water all day long, which is really refreshing.

"Hey, what's wrong with you, Fourth Sister, have you forgotten how Fifth Sister disappeared?" Ryuji also began to remind Ryuji.

"This can't be confused at all!" Long Si hurriedly clarified, "When the fifth sister came out to run around, she was just an ignorant girl, easy to be deceived by gangsters, this girl's IQ is so high, who can fool me?"

"You are so arrogant and arrogant, you will suffer!" "The third princess of Long was also anxious.

But Long Si was still unmoved: "All in all, I just won't leave, you go back and inform the old man and let him arrest me, I'm not afraid!"

"Forget it, if you don't leave, forget it, let's go back!"

Long Er said happily: "But I think the environment of Snow Grain City is quite good, if you leave tomorrow, it will be too hasty, at least you will have to play here for more than ten days, and then you will leave!"

"That's right!" Long Si was overjoyed, "It's still the second sister who knows how to enjoy life, they want to leave and let them go, let's play outside for a few days before leaving, don't worry, I will protect you." ”

On the third day after Qin Xuan returned to Snowgrain City, a huge flaming bird landed in the City Lord's Mansion in Snowgrain City!

The person who came was the messenger of the Phoenix of the Lord of the Firmament, and he came to Qin Xuan to "negotiate".

Qin Xuan took a group of important members of Snow Grain City to greet the envoy of the Phoenix.

The phoenix did not transform into a human form, but maintained the appearance of a giant firebird.

When Qin Xuan came to a place more than two feet in front of him, he could feel a scorching heat wave coming from his face, and he felt like he was standing next to a brazier.

"I'm Lord Phoenix's emissary, Fire Phoenix!"

The Fire Phoenix said slowly: "The people of the Phoenix are willing to give you one percent (1%) of the Heavenly Waterfall resources, and invite you to join our Sky Clan!"

"The Firmament Clan is really willing to sacrifice blood in order to pull people!"

Long Si stood next to him and watched the excitement, and made a provocative remark to provoke the fire phoenix: "Even the heavenly waterfall can be willing to take it out?"

Qin Xuan didn't know much about the Heavenly Waterfall that the Fire Phoenix was talking about.
