One billion years of longevity

After Yuemei left, Yang Zhen looked at the time and found that I just arrived at noon.

Counting, there is still two and a half days from the auction, and the time-to-adjustment and cultivation should be reached.

Just as Yang Zhen wrote a 'Xie Guest', when I was ready to close the guest, Zhu Jiu ran.

After following her, there is Zhu Wei.

If Zhu Jiu is coming, this is more and more touched, and Yang Zhen refuses to see it. But her sister Zhu Wei also came together.

Yang Zhen wants to rest, and he can't refuse to reject Zhu Wei outside the door.

Immediately, Yang Zhen Da opened the door and personally welcomed Zhu Wei in the hall.

The two are sitting around, Yang Zhen got up and down, Zhu Wei, only don't see it, Zhu Wei has lost skin, the skin has no previous water luster, and even the end of the circle is also black, obviously these days have not it is good.

Only her pair of beautiful eyes is still as bright as the past, and even the depths of the eyes, I haven't had a self-confidence that I have never had before.

Yang Zhen played Zhu Wei's eye, revealing the opening of the colored color: "Zhu Wei, did not see you in these days, did not find you in the school. I heard that you please leave, but I don't know these days, you Where did you go? "

"I hiring information on the newspaper, I went to a laboratory in the Chengbei Industrial Zone to go to the assistant."

Zhu Wei is very honest. "In recent days, although it is a continuous class, staying up late, it is very hard. But fortunately, the test product has successfully made some achievements. Today's laboratory holiday, so I deliberately come to see you, and Explain to explain the situation I have this day. "

His voice just fell, and Zhu Jiu next to reveal the look of the invited power, robbed: "After Zhu Weisie returned home, he hugged the quilt, and went to rest. Or I reminded her, say Yang Zhen brother I am looking for her, so she will come to see you! "

Yang Zhen listened, and he couldn't help but move.

It seems that Zhu Wei is really tired. When I got home, I slept.

However, I heard that Zhu Jiu said that Yang Zhen has been looking for her, she still dragged the tired body and ran to see Yang Zhen. It can be seen that Yang Zhen is in her heart, or is extremely important.

This makes Yang Zhen, can't help but have a touch of movement.

It is Zhu Wei, the understanding of the people, and it is good for others. From this point of this, it is gentle and thoughtful, and the character is a few women in Sui, Yue Mei, the best one.

Just when Yang Zhenxin was moved, Zhu Wei took out a square metal square from his small handbag and placed it in front of Yang Zhen.

I saw her pretty face, showing a brilliance of exciting: "This metal is my laboratory, working hard for a few years of crystallization. I deliberately bring you today, I want you Take a look. "

"Artificial metal?"

Yang Zhen met, the look is moving, reach out, head towards the size of the slap, three-inch square metal blocks, and grabs.

The servant is inserted, Yang Zhenbei is a pick, showing a surprised color.

Because this metal is more lightweight than the imagination, give people a feeling, it seems that this metal block is the same.

Yang Zhen took him in his hand, look left and right, I saw this square metal, even a slit of a slit, it was natural, smooth as a mirror.

Extending your finger, Yang Zhen lucky a strong strength, tapping the metal block.

"Ding!"

The metal block was trembled, and a pleasant tremble was sent.

"Ok?"

Yang Zhen heard the voice, can't help but surprised, because light from the sound to judge, the firmness of this metal is excellent, and it is an excellent mechanical metal.

"Air aluminum?"

Yang Zhen is trying to ask.

"It is ruthenium, which is added with ruthenium, belongs to a alloy product." Zhu Wei explained.

Yang Zhen heard his words, and his face was revealed.

Boys is an extremely rare metal. It has an content in the crust, about one billion, only greater than and radium, more precious than diamonds.

Moreover, its melting point is extremely high, second only to tungsten, reaching 3180 °. Moreover, it is not possible to form alone, is a companion of other metals, so it is very difficult in nature.

In addition, the strength of ruthenium is high, good plastic, at high temperatures, rapid cooling or rapid temperature rise, and at the same time, there is still a long time, not easy to destroy and crack.

Therefore, it has been widely used in the engineering community. It is mainly used for jet aircraft and rocket engines, about 80% of rhodes worldwide, are used to produce aerospace engines.

Such precious things, so high-precious technology, ordinary laboratories, there is no strength to participate.

Does Zhu Wei want to be a scientist in an aviation engine in the future, so I will go to the laboratory in advance?

In the heart, Yang Zhen looked at Zhu Wei, and asked: "Which factory in which you go? In my impression, I don't remember the town of Zhenyang, where is the factory with the aviation industry Is there a relationship? "

"You want to be wrong. This metal, although mostly used in the aerospace engine. But there is also a small part, used in other fields."

Zhu Wei explained: "This metal product is essential in some areas that are extremely precise, and requires extremely high load capacity. The simplest example is that you have a few days in the Huaibei Provincial Wudo Pre-selection. The 'semi-robot' Sima Qin, Sima Li son. Their transformed body uses considerable such alloy products. "

When I heard this, Yang Zhenbei was wrinkled.

"You went to Sima Family Lab?"

I heard Yang Zhen, sitting on the side, I have always heard Zhu Jiu in the fog, it is also a glimp.

It is to know that Sima Family is now with Yang Zhen, which is an incompatible water, quite grievances, and the enemy is deep.

At this moment, if Zhu Wei is ran to give the Sima family, it is really realistic.

However, in the face of Yang Zhen and Zhu Jiu's questioning, Zhu Wei is slight smile.

"There is no national border. That laboratory, behind the national financial support, therefore is a military enterprise. It is only the technology they study, which is the Sima family, Murong Shi family, which is used."

"This way." Yang Zhen listened, the original Shen Dynasty, I was relieved.

But the Zhu Jiu, but it is still confused.

"Sister, what do you mean? How can I not understand? Do you have to help the Sima family?"

Zhu Wei listened, touched the small head of Zhu Jiu, patiently explained: "Sister, unfair known, gun is a very dangerous weapon. But it is dangerous, it is also necessary to distinguish it. Take it in terrorists, The violent molecules are dangerous goods. But if they are soldiers who have defended the country, in addition to the stormless police, it is justice. "

"I understand."

Zhu Jiu Tie said: "The sister is gun?"
