I hand over the Wanjie trading system to the country

Thanks to @隐闲阴沙的阿斗 for the {inspiration capsule}, refill~

This is the biggest gift I received in Tomato, thank you, I will add another chapter.

Thanks to @#四菜一汤# for discovering Huadian, the new use of the exchange machine~

"Kanglai, can you give me some raw ore? It's the helium mine you just mentioned." Chuno said excitedly.

"Of course, but can you use Blue Star's technology?" Conley asked. "Interstellar has special transformation equipment."

"There is always a way to research it, isn't it?" As long as you have something, are you afraid that you can't find out how to use it?

"Then wait for me, I don't have the raw ore with me." After finishing speaking, Kang Lai left the supermarket and went home to help Chuno get the raw ore.

Kang Lai came back after a while, and Kang Lai's elder brother came back with him. Kang Lai's elder brother went out to give flowers, and when he came back, there were only 4 legs left.

"Ah! Kang Lai, what happened to your brother? And your father?" Chuno asked quickly.

"The five-leaf flowers outside are all crazy, and we are scared to death." Kang Lai patted his chest with lingering fear. "Fortunately, my brother dragged me to run fast!"

"They won't rush into the supermarket, will they?!" Chuno panicked.

"Don't worry, it won't happen." Kang Lai smiled confidently. "My eldest brother and I locked the door from the inside, and my father couldn't come in."

Chuno: ...you are really big brothers and sisters of your father, you are really filial to your father.

"It turns out that this passage can be closed from your side?"

"No, the passage is inside the supermarket in the mining area, and we closed the gate of the supermarket."

"By the way, the raw ore you want!" Kang Lai took out a fist-sized ore from his pocket and gave it to Chuno.

The ore was transparent, and Chuno almost missed it when he took it. The researcher brother at the side saw it, and quickly took the ore from Chuno's hand.

"Is the density so high?" Chuno wondered, "I remember that liquid helium is not very heavy."

"Under a standard atmospheric pressure, -268.92 degrees Celsius, the density of liquid helium is 124.73g/l, and the density of gaseous helium is 16.757g/l." A researcher brother added.

"The ore in my hand should weigh about 10 kilograms."

After speaking, the researcher brother seemed to feel that he was not rigorous, and then took out a high-precision electronic scale from his backpack.

"13.6731 kilograms."

Chunuo: ...why do you have such a thing as a high-precision electronic scale in your bag.

"By the way, little boss, can I use your currency exchange machine today? It didn't work last time."

Chuno nodded, and took Kanglai to the exchange machine. Last time, Kanglai also said to use the exchange machine, but was interrupted by the flowers.

"Do you know the difference between those eggs of different grades?" Chuno asked curiously.

"That's why I came here." Kang Lai was very excited, "I found that the mining efficiency of worker insects hatched from different levels of insect eggs is different."

"The c-level is the slowest, the b-level is 4 times faster, and the a-level is 8 times faster, but there is not much difference in the time they can work."

"As for the workers hatched from the egg of the ss-level, the mining speed is 16 times that of the c-level, and the working time is doubled."

"Didn't you find out before?" Chuno asked.

Such an obvious difference should have been noticed before.

"We released tens of thousands of worker insects at a time, who would pay attention to those!"

"Yes."

Before coming to the exchange machine, Kanglai seriously took out three large boxes of insect eggs. According to visual inspection, there were about 100 eggs in one box, and they were densely arranged in the box.

It seems that Chuno's striatophobia is about to commit, but the neat arrangement makes the obsessive-compulsive disorder feel extremely comfortable.

Every time Chuno glanced at Kanglai's box containing the eggs, he jumped back and forth between numbness in the scalp and refreshment in body and mind.

"Brother, come help me." After Kang Lai finished speaking, with his brother's support, he sat tremblingly at the exchange port of the exchange machine, "I want to see what level of mining bug I am."

Chuno:! ! !

"Brother, don't do it!" Chuno was about to go crazy, "You will be taken back!"

[The exchange machine is prohibited from exchanging life forms! 】

Fortunately, this creation group is not so crazy, accepting everything.

"Hey... No, isn't the egg a living body?"

"Theoretically, an egg is not a living thing until it hatches a chick."

"So eggs are generally regarded as vegetarian dishes." The little brother continued to popularize science.

"Is there such a saying?" Chuno was shocked. "Why do I feel like you're fooling me?"

[This statement is controversial. At present, the more accepted statement is that whether an egg is considered a meat dish depends on whether the egg has been fertilized. 】

Kang Lai was a little disappointed that he couldn't recognize his level, so he could only test the eggs he brought one by one.

The first two boxes had the most C-grade eggs, followed by B-grade eggs, and there were a few eggs of A-grade, but there were only about 10 eggs in the two boxes of SS-grade eggs.

And the third box of eggs is very powerful, any one is ss grade, and sss grade accounts for at least one-third.

"Wow, Kang Lai, how come this box of eggs is of such a high level?"

"This box was born after I ate the five-leaf flower." Kang Lai said, "After eating the five-leaf flower, the speed of egg production has also increased a lot."

"What's the difference between the sss-level workers and others?"

"I don't know, I haven't hatched yet."

"It takes significantly longer for sss-level eggs to hatch."

The researcher brother who was watching from the side had a thoughtful expression.

"Kanglai, do you have crystals or that black impurity?" the little brother said suddenly.

"Here, here." Kang Lai took out the black impurities he had just collected.

The researcher brother directly put the drop of black impurities at the exchange port.

[B-level virus inhibitor condensate 218g, estimated value is -20928 points. 】

Chuno:!

"Blind student!!! You discovered Huadian!"

At first, I thought that the exchange machine was of little use, but it turned out that no one had discovered its real use.

The little brother was very excited, and tested other materials that had not yet been sent to the research institute.

"Great, so we can get a first look at these things."

"It's great to be able to roughly tell what something is with a name, and to be able to roughly tell what they're worth with a rating and an estimate."

"By the way, let's test the ore just now." Chuno suggested.

The little brother quickly took out the ore from the special safe and put it in the exchange port.

[c-grade solid helium 13.4858 kg...]

"No, this weight is wrong!" The little brother frowned, "It was 13.6731 kilograms just now."

"Could it be... volatile?" Chuno guessed. "Kang Lai, will it be the same in Interstellar?"

"I don't know either. The raw ore will be shipped away soon after being dug out."

"But the ore transport spaceship seems to be specially made."

"Ahhhhhh! Quickly, change the container, change the airtight one." The little brother panicked and yelled to change the airtight box.

At this time, Dean Hu also rushed to the supermarket with the researcher, and quickly ordered that all the boxes be replaced with sealed ones.
