I hand over the Wanjie trading system to the country

In the mining worm living area, Kang Lai was surrounded by a group of mining worms when he walked out of the passage with flowers.

"How about it, Kanglai, did you bring the five-leaf flower?"

"How much did you bring? How much does a Blue Star human flower cost?"

"Why hasn't he taken it out yet, did he not buy it?"

The mining bugs were chattering, and Kang Lai yelled for a long time.

"There are not many five-leaf flowers, everyone is first come, first served!" Kang Lai couldn't help but throw the space grid into the air after saying this.

The space grid is set to open with a delay, and when the time is up, five-leaf flowers rain down in midair.

The mining bugs went into a collective rage stimulated by the strong fragrance of flowers, and the whole mining area was buzzing.

The glass made by the blue mine in the living area could not withstand this wave of vibration attack, and it shattered to the ground.

"Damn, it's a good thing I didn't go to the supermarket. If I did, the little boss and the others would be cold on the spot." Kang Lai picked out his ears, spread his wings and quickly returned to his home.

"Father, mother, brother, I got something good, come quickly." Kang Lai immediately closed the window and locked the door after returning home.

"What?" Kang Lai's family asked curiously.

The Kanglai family all work in the mines. Mining bugs need to work for 150 years, and then they can choose freely.

"Five-leaf flower!" Kang Lai didn't hold back.

"What?" Kang Lai's family almost dropped their jaws in shock, "Five-leaf flower??? Is it the five-leaf flower we know?"

"That's right!" Conley nodded proudly, "Don't ask me where I came from, time is urgent, I will explain to you later."

"Hurry up and eat." After speaking, Kang Lai directly took out a bunch of five-leaf flowers.

Kang Lai's family members were still full of question marks, but after seeing so many five-leaved flowers, they immediately jumped on it.

Fortunately, there are enough five-leaf flowers brought home, and now Kanglai's family is showing off five-leaf flowers.

Kang Lai guarded nervously at the door, for fear that other bugs would break in.

The mining worms in the open space outside have gone crazy, and more and more mining worms are joining.

"Father, mother, brother, hurry up." Kang Lai urged anxiously, he had already seen someone approaching his home.

At the same time that the door of Kang Lai's house was smashed open, Kang Lai's family members had already completed their physical "evolution", and now they had already started to feel sick when they saw Wuye Hua.

Seeing this, Kang Lai put the five-leaf flower into the space grid and threw it out of the window.

"It's all in that space grid, and my house is gone!" Kang Lai said and raised all his hands. "There is no permission, you can open it directly."

The already furious neighbors ran downstairs quickly.

Kang Lai let out a long sigh of relief. Fortunately, there are real five-leaf flowers, otherwise he would not be the only one who faded in the house.

After collecting the black impurities from his family members, Kang Lai finally told his family members about the matter.

"There is still such a thing!" Kang Lai's family was shocked, "Then can we go and see? Our current situation is stable, right?"

"Okay, not wanting to eat five-leaf flowers means stability." Kang Lai nodded, "I just plan to ask you to go with me."

"The channel will be closed tomorrow night, and it is still a question of when it will be opened next time."

"After a while, everyone will go to the supermarket with me. My elder brother will help me deliver flowers to other mining bugs, and my father will help collect the crystals."

"My mother and I went to buy goods together, and brought all the space grids and refined ore at home."

"Purchase?" Kang Lai's family was at a loss.

"Yes, the channel will be closed soon, and those fools only know how to buy, buy, buy, and eat."

"And I, the smartest bug in the interstellar world, am ready to stock up."

"Think about it, after the channel is closed, the goods we have..." Before Kang Lai finished speaking, the whole family understood.

After the Kanglai family figured it out, they took the space grid and all the refined ore at home and went to the supermarket quietly, regardless of the demolished door.

If it weren't for the space grids that are only sold in specialized stores, they would like to buy 10 and 8 more.

"Little boss, I'm here again!" Kang Lai brought his family and found Chunuo impatiently as soon as he entered the door. "This is my father, mother, brother."

"Hi, I'm Chun Nuo, nice to meet you." Chuno greeted Kang Lai's family with a smile.

"Hello, little boss!"

"Kang Lai, how is the situation on your side?" Chuno was still quite worried about the situation on Kang Lai's side.

"Well, it's still on!" Conley said, "No matter what they do, they won't be able to calm down for a while."

Hearing Kang Lai's idea of ​​buying goods, Chuno couldn't help giving him a thumbs up.

"Look at what you want? If you buy a lot, the supermarket doesn't have that much stock, and you have to wait for the merchant to deliver it."

"Little boss, I only brought eggs, star coins, and refined ore with me this time. Let's see what kind you want?"

"Refined ore." Chuno said without hesitation.

Although I don't know what refined ore can do, but things that are very precious in the interstellar world must be good things.

"Little boss, you don't even know what refined ore is for, so you are sure you want refined ore?" Kang Lai didn't understand.

"Things that are precious in the interstellar world must be good things." Chuno said with certainty, "But...what can refined ore do?"

Conley:...

"Refined ore is the product of secondary extraction of slag, so the properties of refined ore are closely related to the type of slag."

"Refined ores are mainly divided into two categories, pure refined ores and mixed refined ores."

"But no matter what kind, the purity of refined ore is 7-8 times that of similar ores."

"Only mining bugs like us can produce refined ore, not worker bugs."

“That’s why refined ore is scarce and the price is very high.”

"The mining area where I am mainly mines helium ore, so the refined ore I can produce is also pure helium refined ore."

Chuno was a little confused, pure helium... mine?

"Wait, Kang Lai, I'll ask a professional." Chuno frowned and called Dean Hu.

"Dean Hu, can helium be solidified?"

"Huh? In theory, yes."

“What conditions must be met in theory? Can we do it?”

"High pressure and low temperature." Dean Hu was at a loss, but he still answered Chunuo's question, "The equipment of the Kyoto Research Institute is fine."

"What's the situation?" Dean Hu asked.

Chunuo told Dean Hu about what Kang Lai had told her just now, and Dean Hu was startled and sprayed a mouthful of tea on the assistant.

"Cough cough cough, you... what are you talking about? Helium... helium ore? Solid helium?" Dean Hu's tone was full of disbelief.

"I'm not sure now." Chuno thought for a while and said, "Kanglai only said helium ore, and the pronunciation is like this. Maybe I was wrong."

"You are waiting for me at the back door. I will bring people and testing kits here now." Dean Hu hung up the phone directly, and rushed to the supermarket in a hurry.

"Kanglai, is the helium mine you're talking about the kind of helium from our Blue Star?" Chuno regretted calling Dean Hu without asking clearly.

"Wait for me to go to your website to have a look." Kang Lai opened his star information and searched.

After searching for a long time, Kanglai also discussed with his family members before reaching a conclusion.

"It's the same." Conley nodded affirmatively, "The helium ore is the solidified helium that your blue star said."

After listening to Kang Lai's answer, Chuno felt his scalp numb, he couldn't breathe, and his heart beat extremely fast!

You must know that helium is an important strategic resource known as "gas chip".

The reason why nitrogen is scarce is firstly because it has a wide range of uses, and on the other hand because nitrogen cannot be obtained through artificial preparation and is a non-renewable resource.

The content of helium in the air is very low, only about 0.000524%, and the cost of extracting helium from the air may be more expensive than the same volume of gold.

In 2020, Huaguo will import 3700 tons of liquid nitrogen, accounting for 95% of the total.

That's why Chuno was so excited when he was sure that the helium mine that Kang Lai said was solid helium.

It seems that the most important thing in this transaction with mining bugs is not the crystallization, but the ore, whether it is refined or not.
