"I have a brief chat about this matter after An Gang and I. It's not a big problem, but I still have to ask you to wait a few more days. Now I am not in the imperial capital. I will discuss it with An Gang after I go back." Yan Yuyan explained.

"Okay, then I'll trouble Mr. Yan." McAr breathed a sigh of relief, and if he didn't refuse, it meant that there was hope.

It can be said that it was half successful.

Then there is the problem of chips.

"It's okay, by the way, Mr. Mike, I have a question."

"Mr. Yan, you said?"

"If you want tempered fibers, you can place an order directly with Angang. Moreover, their prices are not high. I think you can accept it completely, right?" Yan Yuyan asked in confusion.

"After our testing, the fields of tempered fibers are available are very wide. If we import large amounts of steel from your country, not to mention the cost, the output will be a big problem," explained Mike.

"You mean the yield is very large, they can't satisfy you?" Yan Yuyan raised her eyebrows.

"It can be understood this way, but there is another very important factor. We need to use it on special equipment, so we have to be assured that we have to produce it ourselves."

"I understand, I'll contact you later in a few days." Yan Yuyan instantly knew that what Mike was talking about was used for military purposes, so she said, "I'll give you an answer at that time."

"Okay, then I'll wait for good news from Mr. Yan."

"Okay, let's contact you later."

"..." Yan Yuyan hung up the microphone, threw her phone, threw it beside her pillow, and asked Liu Tianwen: "Where are you going to play today?"

"It's raining outside today, you still want to go and have fun." Liu Tian pointed out the window.

"Is that right?" Yan Yuyan turned around and looked out the window, rolled her eyes: "The curtains blocked it, how did you see it raining?"

"If you don't believe me, get up and take a look?" Liu Tian blinked.

"What if I can't get off?" Yan Yuyan looked at Liu Tian who was unquestionable and was dissatisfied.

"Why don't you?" Liu Tian raised his eyebrows and hooked his finger: "Make a bet."

"Just bet, I'll go see."

"Wait, let's talk about the bet first..." Liu Tian saw Yan Yuyan lifting the quilt and was about to get out of bed and hurriedly grabbed it.

"you say?"

"..." Liu Tian put his mouth to Yan Yuyan's ear and said a few words.

"I don't want it." Yan Yuyan's face seemed to be dyed with red clouds.

"I dare not..." Liu Tian raised his eyebrows.

"You think beautifully, I'll go see it." Yan Yuyan bit her lower lip, stared at her, and ran to the window, pulling a crack in the curtains.

"How is it, I didn't lie to you."

"How did you know?" Yan Yuyan jumped back to the bed and retracted into Liu Tian's arms.

"I just got off the ground so loudly, but I heard the sound."

"That's not counting. You're so slutty, you know clearly..." Yan Yuyan kissed Liu Tian directly on the face: "I reward you with a kid, it's over."

“Tsk tsk tsk…”

"Then I can't go out today." Yan Yuyan cleverly changed the topic: "We will study "Tianyu Environmental Protection". Yesterday Chen Lin sent me a message saying that the detailed information had been sent to the email address."

"Okay." Liu Tian stretched out his hand, took over the work tablet placed on the bedside table, and clicked on the company's email.

"Do you think there is any possibility of improvement?" Yan Yuyan sat up, put a pillow behind her back, and pulled down the quilt.

"Use different chemical materials to degrade and remove poison?" Liu Tian glanced at the information on the screen for a while: "Although there are unique features, they are very limited and it is difficult to reduce the cost. There is another point that the possibility of upgrading is too small."

"Isn't this the case when dealing with sewage now?" Yan Yuyan reached out and slid the screen down.

"I saw a paper that used the powerful absorption capacity of plants to strip away pollutants in sewage just like absorbing nutrients." Liu Tiandao.

"Is there such a technology?" Yan Yuyan looked away from the screen and looked at Liu Tian squintly.

"This is a direction, you can try it, at least it works in theory."

"Where does the pollutants absorbed by the plants go? And the plants grow so slowly?" Yan Yuyan asked.

"I have studied it in the form of fruits before, but later because it was difficult and I had no money, I gave up." Liu Tian explained.

"???" Yan Yuyan's face said: Say it.

"It is the organisms that use aquatic plants to treat wastewater. The process is quite simple, mainly using their rhizomes, bacteria and other microorganisms."

"When these plants have a large number of rhizomes stretched into wastewater, microorganisms absorb minerals and their organic chemical pollutants in the wastewater, thus producing by-products that can be absorbed by plant rhizomes as food."

"For example, sugars and amino acids, plants in turn provide oxygen and low-grade nutrients and minerals for the rapid growth of microorganisms..." Liu Tian briefly introduced.

Daodao...Liu Tian said a lot of terms:

It means one thing:

It is to use cultivated plants to grow directly in sewage, and use the root system to directly absorb pollutants in sewage to form fruits.

"If plants are used to purify sewage, this is not a novel thing, but if you want to extract minerals, it should be impossible, right?" Yan Yuyan looked at Liu Tian with a suspicion.

"Beauty, you have to believe in your husband." Liu Tian made his position and pinched someone's small chin.

"This is not a question of not believing it, okay." Yan Yuyan tilted her head: "Even if you successfully extract a mineral, what about your time?"

"In terms of the growth cycle of plants, if it is one or two years, what do you think this technology is useful? Do you think a city can allow you to use one or two years to treat a pool of sewage? When you finish processing, the city will be flooded."

"At the current sewage generation rate, if it cannot be disposed of within ten days and half a month, then no matter how good the technology is, it can only be considered a concept product." Although Yan Yuyan is not a material student, she is also a top student.

The key points were drawn out directly.

"Did you listen to an online term?"

"What?" Yan Yuyan glanced at Liu Tian.

"As long as I'm fast enough, you won't even see the taillights."

“…”

"It will definitely not work at ordinary speed, so think about how to improve this efficiency and how to collect the extracted minerals together." Liu Tian put the tablet in his hand back on the counter next to it.

"Then do you mean, do you want to try it?"

"Well, give it a try, it won't waste too much time anyway."

"Okay..." Yan Yuyan shook her head and said, "Okay, try it, leave the mobile phone screen to me. By the way, when you make this plant, you can get the extraction device out."

"Can."

“…”

Lifeng Empire PG headquarters;

Kudak looked at the documents in his hand and his face looked very ugly.

"It's like a supervisor-level meeting."

"Yes!" Kudak's assistant also felt that the atmosphere was not right and ran out quickly.

Half an hour later...a meeting room.

"This is a sales report sent back from the White Alliance. Let's take a look." Lao Ku directly threw the documents in front of him in the middle of the table.

"?"

“…”

After I walked around the file, it was already half an hour later.

The entire conference room was terriblely quiet.

"From the 1st to now, our sales in the White Alliance have dropped sharply by 20%, and in the Middle East, it has also decreased by 10%. "Old Ku glanced at the corner with a serious face: "Now, Xingxing Group has been involved."

"Our DIS battery will not be available next month. With our relationship with Lifeng Empire and Tianyan Technology, it is impossible to get the goods in advance."

"The root of the problem is the DIS battery." The bearded man sitting on the left said: "President, now you can buy DIS materials from both the South Band and the Sun Kingdom. Can we buy some from them?"

"We sell 20 million units per month. If the DIS material is based on the normal battery usage, it will cost at least 400 tons, not half and half, and that will be 200 tons, not one or two tons. How do you think you can buy it?" Lao Ku asked with a frown.

"!!!" No one spoke again in an instant.

"How is the laboratory?" Lao Ku saw that no one spoke, so he called him directly.

"President, the power storage capacity of our graphene batteries has been significantly improved. Although they are not as good as the DIS batteries of Tianyan Technology, I think it should be fine if I use them on mobile phones." said a tall man with glasses.

"How much worse than DIS battery capacity?" Lao Ku is more concerned about data.

"half."

"Only half."

"The experiment is coming to an end now, and it can be produced on a large scale in half a month. In terms of cost, a battery is about 150 yuan (soft banknotes)." The tall man added: "If it is produced in large quantities, it should be reduced to about 100 yuan."

"Sustaining flights for three days, speeding up." Lao Ku pondered for a while and asked: "Now what Penghua and others sell 5G mobile phones, can our 5G chip cost be reduced?"

"We have been expanding now, but if we want to reduce costs, the main difficulty is the raw materials."

"The raw materials should be reduced soon. Now the four mobile phone companies in Penghua and others have reduced at least half of the chip orders, so the raw materials will naturally be more, and the supply will be oversupply at that time."
