System: If the host wants to raise the little dragon girl for a long time, it is best to supply her with a limited supply of crystals, and don't let her develop the habit of overeating!

Qin Xuan replied with a wry smile: "Then you should have told me earlier, he had seen all the things, and now take it away and don't let her eat it, she won't bite me to death?"

System: It's not enough to bite you to death, the young dragon's docile personality will not hurt people easily, but if you steal her food, it will seriously affect her favorability towards you, and it will be difficult to be friends with her again.

There was no way, Qin Xuan could only "with tears in his eyes", watching the little dragon girl eat up all the crystal refining of a unit!

"Little brother, do you still have Long Jing here, you haven't eaten enough neodymium yet?"

"Bang dang!" Qin Xuan's body went soft directly, and he fell off the stool on the spot.

Qin Xuan had also considered it before, to keep a little dragon by his side, not to keep a pet, and it was good to be a younger sister.

Now it seems that Qin Xuan knows that he is really thinking too much, and we can't afford to raise her at all!

While his heart was extremely tormented, Qin Xuan also stubbornly explained: "Little Dragon Girl, I see that you have almost eaten enough, let's go to the beach to pick up shells, and I will go find you Long Jing to eat in the evening!"

"Okay then!" the little dragon girl patted her stomach and replied, "Then you should find me more dragon crystals at night!"

Qin Xuan grinned and replied stubbornly: "Okay, don't worry!"

Running to the beach, Qin Xuan mobilized the fishman warriors to work together and picked up a large number of shells for the little dragon girl.

And while picking up shells, Qin Xuan deliberately learned about the knowledge of crystal refining.

Refining Crystal is the name of the interstellar meeting, and the dragons like to call them "Dragon Crystal".

Since the little dragon girl likes to call it Dragon Crystal, let's call it Dragon Crystal.

The source of dragon crystal is to collect dragon crystal ore, and under normal circumstances, the kind of dragon crystal eaten by the dragon clan is not very pure dragon crystal ore, and the refining crystal sold in the interstellar is high-purity solid energy after refining.

The content of dragon crystal is determined according to the quality grade of the ore vein!

From low to high, it is divided into: inferior veins, ordinary veins, medium veins, superior veins, superb veins, unparalleled dragon veins, and dragon crystal fountains.

The energy purity is: 15%, 35%, 50%, 75%, 85%, 95%, 99.8%.

Among them, the top-notch Dragon Crystal Fountain can spray energy in a liquid way.

The liquid dragon crystal sprayed out is even purer than the high-purity refining crystals sold in the interstellar world, and it is a truly priceless treasure.

Qin Xuan glanced at the surrounding area of 100 kilometers with his Eye of Insight, and did not find any crystal ores.

But the system told Qin Xuan: Your mining robot has collected some weak-grade crystal refining ores, you can go to them and inquire!

"Weak grade crystal refining ore?" Qin Xuan frowned.

System: A crystal-refining vein with an energy purity of less than 15% is not even the lowest-grade ore, it can only be called a weak-grade crystal-refining ore!

Qin Xuan summoned a bearded robot through the system and asked him to find out the source of the ore.

The bearded robot gave Qin Xuan a location, and their ores were all picked up from this location.

The location provided by the robot is a fast-flowing river valley with no crystalline veins around it, and it is likely that the ore was washed down from the mountains upstream.

The results of the analysis of the system are that there should be a crystal smelting mine upstream of the river, and the miners collect and transport the ore with high purity, and some ore with low purity is thrown into the river as garbage.

After analyzing this result, Qin Xuan immediately ordered the robot to drive a helicopter up the river to search for the coordinates of the location of the ore vein.

The robot's work efficiency is very high, and it takes more than ten hours to detect the specific location of the ore vein.

The location of the ore vein is 15 kilometers north of Linghu Village.

In this vein, there are a large number of orcs active, and it should be the territory of the orcs.

Intelligence footage shows that the miners are mostly minotaurs, but the overseer is an elephant-trunked giant.

The elephant trunk giant looks like an elephant, but the elephants on the earth are almost the same, and in fact, these guys are also four-legged creatures, not even humans, not even orcs.

But on the ground of the wild world, everything is based on strength.

The elephant-trunked giant has a huge body, infinite strength, and a strong combat power, so the mine is theirs!

Directly running to grab the ore vein can maximize the benefits, after all, Qin Xuan is now strong, and it is not a problem to defeat these elephant trunk people.

But Qin Xuan is not a robber, this kind of cunning and robbing, Qin Xuan doesn't like to do it very much.

The Elephant Trunk people themselves do not consume dragon crystal ore, they generally sell the collected dragon crystal ore to the sea tribe to earn Shanluo.

In the sea of the savage world, there are also dragons, and they are the big consumers of dragon crystals.

There is also Zhongzhou in the Wild Continent, where there are many strong people like clouds, and those big families, big forces, forging magic weapons, cultivating pets, and refining pills, can all use crystal refining, and crystal refining ore is still very popular.

The dragon crystals collected by the elephant trunk mining were basically sold to Binhai City.

The price is very cheap, a mountain Luo 100 pounds of ore.

That is to say, the elephant trunk manpower is infinite, and the consignment capacity is strong, and if it is an ordinary human being, I am afraid that 100 catties of ore from Shanluo may not even be enough for freight.

The ore is sold so cheaply, Qin Xuan has no need to mine by himself, just spend money to buy a batch.

Early the next morning, Qin Xuan took a group of Shanluo, a large number of snow particles, and 500 mechanical warriors, as well as Xiaolongnu, Tolan, Sai Xishi and others, and went to the Xiangshan Ore Vein.

Earlier, Sai Si Shi had already sent a group of fish-man warriors to negotiate with the elephant trunk people in the mine to buy the mine.

When Qin Xuan and the others came over, the elephant trunk man had been waiting at the gate of the mine for a long time.

"Humans, how much ore are you going to buy?"

The elephant trunk man said loudly: "If the number is too small, don't bother me, I'm busy right now!"

Qin Xuan replied lightly: "I want 1 million catties of ore!"

"Get the money!" the elephant-trunked man nodded in satisfaction.

Qin Xuan waved his hand, and Sai Xi Shi immediately took out the storage bag and poured out a large amount of Shanluo from it.

The elephant trunk man immediately notified his subordinates to move the goods, and the elephant trunk man is very strong, and an adult giant elephant can carry tens of thousands of catties of ore at a time.

I made a whole 100 big bags, all of them were full, a sufficient amount of 1 million catties.

After the transaction was completed, Qin Xuan asked again: "By the way, Brother Elephant Trunk, we need a large amount of Dragon Crystal Ore, in the future, all the ores in your mine will be sold to us Snow Grain City, I want them all!"

The elephant-trunked man asked, "Stupid human, you don't want the cowhide to blow through the sky, the surrounding mountains are all my mines, can you eat it!"
