Xu Yingxi took the newly discovered ore specimen and went to find Cheng Qingxue.

At this time, Cheng Qingxue was frantically checking the information, trying to find a good solution.

Seeing Xu Yingxi running over with an excited face and holding a piece of ore, she said, "Qingxue, we have a solution to the dilemma!"

With such an excited face, Cheng Qingxue's eyes couldn't help but light up, the biggest dilemma now is the business in front of her.

She's going to make it!

Xu Yingxi told her, "My brother and I investigated the mine and finally spent an afternoon to find an ore that can replace the raw materials of gold ore!"

As soon as these words came out, Cheng Qingxue was immediately excited, she smiled happily, and directly pulled Xu Yingxi to refine it.

"Let's go, let's go to the laboratory to refine it!"

Just do what she says, Cheng Qingxue has always been a man of action, and immediately pulled Xu Yingxi into the laboratory.

After Qingxue's experiment, this unfamiliar ore can be refined, and he was suddenly pleasantly surprised.

"Great, now it seems that this business will definitely be done. Looking at this ingredient and speed, it should be done in ten days!"

Cheng Qingxue looked at Xu Yingxi and said, "You go and tell Xu Yingguang, just tell everyone to work harder, as long as this list of business is won, I will invite all the absentees to eat." ”

She has never been a stingy leader, and suddenly Xu Yingxi was also infected by her smile, and her heart was excited.

If you want to hand over, you still need a progress, this ore is not a gold mine after all, but there is gold content in it.

So there is still a need for a purification process, which requires Xu Yingxi to help.

Xu Yingxi had never been exposed to these things, let alone the techniques of refining.

"It's okay, you come with me, I'll teach you to purify, and you can master the skills yourself in the future. ”

For Cheng Qingxue, who majored in geology, this kind of refinement is pediatrics.

Cheng Qingxue asked her to write down the process while doing it.

In the first part, the ore with a gold content is mashed into a container, and a solution of hydrochloric acid, edible salt and nitric acid is added.

In the second part, wait for a few hours, and you can see a yellow, saturated solution in the solution. The precipitate is then filtered to obtain a tetrachloroauric acid solution, followed by a few drops of tin dioxide in the solution.

In the third part, metabisulfite and ice water are added to the solution, wait for 10 minutes, and then filter the bottom precipitate.

In the final step, wait for the sediment to dry thoroughly and then heat it at high temperatures.

Cheng Qingxue's series of explanations made Xu Yingxi admire, "It turns out that you know so much." ”

Looking at the bright admiration in the little girl's eyes, Cheng Qingxue was also quite proud, and said, "How can I open a mine if I don't understand this?"

With this ore, ten days became abundant as a substitute.

When it came to the delivery date, Cheng Qingxue directly called Xu Yingxi and Xu Yingguang to go together.

She has her own considerations, and after this incident, Cheng Qingxue found that Xu Yingxi is actually very talented in things in the mine.

The important thing is that she sees the liking in the eyes of this little girl, and she likes the industry.

In fact, all geniuses are only able to go further because they like the industry they are in.

Cheng Qingxue took the two brothers and sisters to the delivery dock together, and saw Li Kaiming waiting there from a distance.

"Mr. Li, have you waited for a long time?"

She was appropriately polite, walked forward with a smile and said, such a big customer had better be able to hold on.

If there is a need in the future, Li Kaiming will still be able to think of her.

Li Kaiming is also very optimistic about Cheng Qingxue's fame, this is a model of a strong woman who is alive and well.

"Miss Cheng is very punctual, and I haven't been here for long. ”

For the delivery within ten days, Li Kaiming also has a further understanding of Cheng Qingxue, a woman.

It is a good choice for long-term cooperation.

Cheng Qingxue beckoned everyone, carried the goods down, and let Li Kaiming's people inspect the goods.

Seeing the goods he wanted, Li Kaiming was very happy, and settled the balance directly at the dock.

"Happy working together!"

Li Kaiming changed his arrogance when he first met, and said with an appreciative smile in his eyes.

Cheng Qingxue looked at his outstretched hand, shook it very naturally, and had a formulaic smile on his face, the same sentence, "Happy cooperation." ”

This list of business was finally successfully completed, and Cheng Qingxue was also relieved.

Back at home, Cheng Qingxue smelled a burst of fragrance and saw the man in the kitchen coming out with the dishes.

Gu Xingshen's appearance with an apron looked a little funny, especially inconsistent with his previous image.

But looking at the table of dishes, warmth flashed in her eyes.

"Alright, sit down and eat, and have a taste. ”

Cheng Qingxue sat down, put a mouthful of food in her mouth, and suddenly felt her appetite widen, and couldn't help but praise Gu Xingshen again and again.

"The matter of the mine seems to be solved in this way. ”

Gu Xingshen made her smile with her eyebrows, obviously in a good mood.

"Yes, we found an ore that could replace the raw material, so within 10 days, the delivery was successfully completed. ”

When Cheng Qingxue talked about this, her eyes were full of smiles.

Thinking of the success of this business, Xu Yingxi still contributed to it, Cheng Qingxue said to Gu Xingshen, "I really didn't expect that this business could be solved so well, thanks to Xu Yingxi." ”

Hearing this, Gu Xingshen raised his eyebrows, and he had the impression that the little girl was a delicate girl.

I didn't expect to have such a mind.

Cheng Qingxue said the ore that Xu Yingxi had discovered, and then said thoughtfully, "Brother and sister Xu Yingguang are very capable and talented people.

I thought, in the future, it would be better to leave the affairs of the mine to their brothers and sisters to take care of, what do you think?"

She had been thinking about it for a long time, and when she came back from the docks, she was thinking about it.

It's just that I don't know what Gu Xingshen's attitude is, so I mentioned it to him in a consultative tone

This is the case.

In this regard, Gu Xingshen didn't have any opinion, "The matter of the mine is originally your hard work, who do you want to reuse, don't worry about me."

As long as it is your choice, I will support you. ”

As long as it is your choice, I will support you. This sentence is inexplicably heartwarming.

Cheng Qingxue suddenly felt as if she had been provoked.

However, it's good that he doesn't have an opinion.

That night, Cheng Qingxue called the Xu family brothers and sisters to have dinner together.

It was said that it was a dinner, but in fact, it was just for them to go to the house for dinner together, and she had an idea to say.

At the dinner table, Cheng Qingxue said directly to the point, "The hero of this time is our little pity, come to us to respect you." ”

Xu Yingxi suddenly looked at everyone a little embarrassed.

After eating a few bites of food, Cheng Qingxue opened her mouth and asked Xu Yingxi, "Does Xiao Xi like the work in the mine?"

Xu Yingxi nodded very sincerely and honestly.
