Watching Jiang Yuan leave with Cheng Qianqian, several scientific research dogs who didn't leave let out a bitter wail.

When the two went downstairs, Jiang Yuan asked curiously:

"You are a girl, how did you want to study metallurgy?"

Cheng Qianqian pulled the hair from her ears and said with a smile:

"Mr. Jin is my undergraduate teacher, although his temper is a little ...... Well, that's what, but he really took care of the students, and basically all the poor students at that time would be properly helped. Now there are a few of us, and the tutor gives each person 2,000 yuan, and if he helps him substitute for the class, he also gives us 30 yuan per class, which is really good in the master's and doctoral supervisors. If it weren't for that, I wouldn't have been able to read it at all. ”

Jiang Yuan then had a different view of the tutor who disappeared the next day, and was willing to help poor students, although he was a little out of tune and his scientific research ability was mediocre, he was always a good person.

The bodyguards very much did not recommend Jiang Yuan to walk at night in crowded places, so Jiang Yuan could only use Maybach to send Cheng Qianqian.

Cheng Qianqian was extremely resistant to this very expensive car at first glance, for fear of being misunderstood by her classmates.

Jiang Yuanjiu couldn't persuade her, so he could only let her walk by herself, and he asked the driver to drive slowly and follow.

Under the dim street lamps on the university campus, a few students walked by from time to time, some sweetly snuggled together, eager to be stuffed into each other's bodies.

Cheng Qianqian was walking with her schoolbag on her back, and the pale yellow light shone on the girl's swan-like neck, which made Jiang Yuan suddenly feel a little moved.

Perhaps, it's good to marry this kind of girl, and it's time for you to talk about a real relationship?

Soon Jiang Yuan shuddered.

What was I thinking!

I'm still young, how could I go to the grave of marriage so early?

I'm sure I'm just looking at other people's headlights!

That's right! I'm a pervert!

......

......

Early the next morning, Jiang Yuan waited for Cheng Qianqian to be ready to start the experiment before opening the 'Xueba Moment'.

Sure enough, with the support of 'Xueba's Moment', Jiang Yuan's hand handicap can also find Cheng Qianqian's mistakes.

Of course, this is not the embodiment of Jiang Yuan's experimental ability at all, it is purely the result of a pile of intelligence.

After yesterday's afternoon's failure, several other scientific research dogs have long lost interest in onlookers, and are busy with their own things in their respective positions.

With Jiang Yuan's support, Cheng Qianqian's experimental techniques have been significantly improved.

Although she didn't make a qualified foaming agent by the end of the 'Peak Moment', she could clearly feel that she was approaching her goal.

Before lunch, Reagent 37 failed.

The scientific research dogs are excited, maybe 100 bottles of manganese steel grit can be consumed today, and a new batch will be made tomorrow!

The scientific research dogs were eating the luxurious takeaway delivered by Lin Ruqing, and if you said a word, they would even fight over the practice phone of the vacuum induction furnace that quickly solidified the next day.

"Hey, hey, I'm still sitting here, you eat me and drink mine, is it really okay to say that?" Jiang Yuan shouted dissatisfiedly.

After a few days of messing around in the laboratory together, everyone was no longer afraid of Jiang Yuan.

Wu Feng even laughed:

"We are all scientific research workers, we must pay attention to feelings, but we must pay more attention to rationality, isn't it obvious that manganese steel grit is exhausted?"

Cheng Qianqian looked at Jiang Yuan apologetically:

"I'm sorry, Jiang Yuan. I'm really bad. ”

Seeing that the girl in the lab was embarrassed, everyone was silent, but they were still there with eye contact, and it was obvious that they were still competing for the next day's phone practice.

The failure of the experiment continued until half past nine in the evening.

Jiang Yuan was helpless about this, with his scum practical level, it would definitely be a disservice to go up and command blindly without the blessing of the 'Xueba Moment', he could only watch Cheng Qianqian fail again and again, while cheering her up.

When Jiang Yuan was about to feel that he had no chance today, Cheng Qianqian suddenly said in a daze:

"Ah, colorless and odorless viscous liquid? Reagent 69?"

Jiang Yuan raised his head suddenly, with an excited expression:

"Quick, quick, take manganese steel grit for experiment!"

Cheng Qianqian carefully operated the No. 69 reagent and slowly flowed into the manganese steel grit.

The manganese steel grit swelled instantly, like foam when washing clothes, but the bubbles on it were very fine, the size of a small hole in a sponge, but they were all airtight.

The 100 grams of manganese steel grit continued to expand, and after about 30 seconds, it completely stopped, by which time it had turned into a square the size of a large loaf of bread, completely supporting the bottom of the entire confined space.

Manganese steel foam!

Jiang Yuan clenched his fists:

"Quick, take it out, I'll try. ”

Cheng Qianqian cleaned it in strict accordance with the conventional steps before taking out the manganese steel foam.

After confirming that it was not corrosive, Jiang Yuan carefully took this hard-won manganese steel foam square in his hand, and it was only a moment of effort, and it had already solidified.

It is an alloy square about 500 cubic centimeters in size, densely covered with fine and neat hexagonal bubble protrusions, and the magical chemical reaction makes these bubbles extremely regular, like a honeycomb.

Contrary to the huge volume, this alloy is only about 104 grams, and the extra 4 grams is the composition of the blowing agent.

The metal cube, which is larger than a loaf of bread, is very light in the hand, making it feel extremely inconsistent.

Jiang Yuan tapped his fingers and made a metallic echo.

Jiang Yuan pressed hard again, it was very hard and stable, without any deformation.

took out a small hammer and struck it a few times, but it still didn't move.

It didn't break after a few more knocks, but it left a slight depression in the part where it was struck, and if you don't look closer, you can't see it at all!

Thrown into the pool, it floated steadily.

"Succeeded?" Cheng Qianqian asked Jiang Yuan in disbelief.

Jiang Yuan smiled and nodded:

"Well, if nothing else. Is there a record of the experimental procedure for Reagent 69?"

"Yes!" Cheng Qianqian still couldn't believe that this alloy, which was very promising at first glance, was actually made by herself.

I'm just a graduate student!

Jiang Yuan took a deep breath:

"Repeat the experiment immediately. ”

Half an hour later, three successes in a row convinced the two that they had really succeeded!

Jiang Yuan finally couldn't hold back his excitement, hugged Cheng Qianqian hard, and said happily:

"You're really wonderful! Today, please work after work and continue to test the performance of manganese steel foam according to the requirements on this piece of paper. I'll make a phone call first. ”

After saying that, I picked up the phone and dialed it.

After Cheng Qianqian was hugged, her body stiffened and her face was crimson, and her voice was like a mosquito:

"Oh. ”

......

......

Half an hour later, Fan Cheng, the chief engineer of the Donghai Shipyard, who looked unhappy, was invited to the laboratory.

As soon as he entered the door, he said unhappily:

"Mr. Jiang, I'm still busy with your draft of the sea city technology, what are you asking me to watch at night?"

I haven't seen him for a few days, and Fan Cheng has more gray hair on the top of his head, obviously breaking his heart for the sea city.

Jiang Yuan excitedly handed over the black manganese steel foam and a document full of manganese steel foam properties, and said with a smile:

"Look at this! It must be very helpful to us!"

Fan Cheng put on his glasses and looked at him suspiciously.

After a moment, he roared with a flushed face:

"It can't be!"

Look at what is written on this document!

This manganese steel foam is five times lighter than water, and its hardness, tensile resistance, and toughness are basically the same as structural steel!

It is very easy to mold, as long as there is an abrasive, it can form the shape of the abrasive tool at one time, and it is solidified in 30 seconds at room temperature!

It is very easy to weld, you only need to apply foaming agent to two pieces of manganese steel foam, and then spray some low manganese steel powder, and press them together!

Also 30 seconds to freeze!

Extremely easy to handle because it's light!

At the same time, it is also corrosion-resistant and resistant to high temperatures......

Fan Cheng is crazy, Jiang Yuan and Cheng Qianqian may not know much about the role of this lightweight material, but he couldn't be clearer.

If it is true, the shipbuilding, automotive, aerospace, construction and other industries will usher in a huge change!

"Quick, I'm going to experiment!"

After 30 minutes, Fan Cheng got a positive answer, some indicators were even better than those on the document, and he said to Jiang Yuan with a serious face:

"Mr. Jiang, maybe you don't know much about what happened, but please trust my judgment, this kind of material is definitely of national strategic significance. I hope you can let your bodyguards obey me for the time being!"

The Donghai Shipyard was originally a military industry, Jiang Yuan naturally had nothing to distrust, he looked at Fan Cheng's cold expression, and then he felt that he seemed to have made something very unbelievable:

"Yes!"

After speaking, Jiang Yuan shouted outside:

"Captain Shen, please come in. ”

A man in black with a calm face walked in:

"Mr. Jiang, what's the matter?"

He is Jiang Yuan's bodyguard captain Shen Long.

Jiang Yuan pointed at Fan Cheng and said:

"This is Chief Engineer Fan of Donghai Shipyard, temporarily following his orders. ”

Shen Long hesitated and said:

"Yes. ”

Fan Cheng immediately said:

"Captain Shen, leave the necessary bodyguards here with Mr. Jiang, and the others will act immediately. ”

"Lock down the entire chemistry building, lock down the experimental materials management office, lock down the school!"

"Control all the students and teachers in this laboratory, and control all the people who have been to this laboratory in the past 10 days!"

"Protect the video surveillance hard drive here, and scrutinize all those who have access to the surveillance!"

"Finally, ask for assistance from the Hua'an Bureau of Qianwan City!"

"That's it, let's do it now!"

Shen Long's eyes were extremely solemn, he immediately understood that something big had happened, but he still looked at Jiang Yuan, and he had to get confirmation from Jiang Yuan.

Jiang Yuan nodded and said:

"Execute the order, and additionally inform Major Su Lin to come over immediately. ”

Shen Long's eyes suddenly lit up, and his face was extremely resolute:

"Yes!

After saying that, he ran out and yelled:

"One team assembles! Two teams assemble! Immediately recall all peripheral personnel and lock down the school!"

With the big movement of the soldiers, the school that had just turned off the lights boiled, and the students all walked to the balcony in disbelief to look.

After a while, the campus radio sounded:

"All students, faculty and staff must stay indoors, do not move freely! Do not leave the school without permission! Attention, this is not a drill! This is not a drill!"
