Magus Tech Chapter 1029: Everything is ready, only the east wind is owed

"Thank you." Li Cha thanked, took the list that Yinuo Gaowa handed over, glanced at it, and soon saw several materials that had not been collected yet, all of which were marked with crosses .

The ones that were not found, to be precise, were two.

The first type, named rhinestone on the list, is actually rhenium.

It is a silver-white metal that is hard, wear-resistant, corrosion-resistant, and insoluble in hydrochloric and hydrofluoric acids. This metal has an excellent feature, that is, heat resistance, with a melting point of 3180 ° C, ranking third among metals, and a boiling point as high as 5627 ° C, the highest among all metals.

This metal also has a "rhenium effect". When it is made into an alloy, it can greatly improve the strength and plasticity of tungsten, molybdenum, and chromium. Adding a small amount (3%-5%) of rhenium can make The recrystallization initiation temperature of tungsten increases from 300°C to 500°C. Just like this, after the implosion nuclear weapon ignites the high explosive, the rhenium-tungsten alloy can squeeze the nuclear material under high temperature and high pressure conditions without being affected.

The second, listed as sweet greenstone, is actually beryllium.

It's a gray metal, brittle at room temperature, with a modulus about 50% higher than steel, and a lower density, so the speed of sound is very high. Under standard temperature and pressure, the propagation speed of sound in it is about 12.9km/s-under the same conditions, sound propagates in the air, but it is only more than 300 meters per second.

Of course these are not important, what is important is that except for trace radioactive isotopes caused by cosmic rays, natural beryllium is almost entirely composed of beryllium-9 isotope with nuclear spin of 3/2. This leads to its relatively large cross-section for high-energy neutrons, which can reach 6 barns for neutrons with energy higher than 10keV, and can quickly reduce neutron thermal energy to below 0.03eV. It is an excellent neutron reflector and neutron moderator.

To put it simply, if it is used as a reflective layer, it can limit the activity of neutrons in a certain range, allowing the continuous nuclear chain reaction to continue, which will help increase the power of the atomic bomb.

At the same time, beryllium will release neutrons under the impact of deuterons and protons, so it can become a source of neutrons under certain conditions to stimulate the nuclear explosion of atomic bombs.

In short, these two materials are very important for the manufacture of implosion atomic bombs.

Rhenium can't be found, but he can still understand.

After all, this metal is relatively rare, and it was discovered very late on the earth. If he really can't find it, he can try to replace it with other materials.

But beryllium can't be found, so it's a bit hard to accept.

Beryllium is much more common than rhenium, not to mention anything else, it only exists in some specific types of emeralds.

Putting down the list, looking up at Yinuo Gaowa, Li Cha confirmed and asked: "Wizard Yinuo Gaowa, the two missing materials on the list, are you really not found at all?"

"Is this..." Yinuo Gaowa hesitated, thought for a while and said, "Wait a moment."

After finishing speaking, he searched through several piles of documents on the table. After searching for a few minutes this time, he finally found a new document. After reading the above content carefully, he came over and said, "Sorcerer Li Cha, according to the report submitted, we have actually found some sweet green stones, and some clues have been found for the other rhinestones, all of which are concentrated in the cable. In a mining city called Rice in the Ma Union. However, it may take a month or two to collect the materials to meet your requirements and ship them back, so the current status of these two materials on the list , is still vacant.”

Li Cha heard this, frowned slightly, and asked, "Could it be that Rice City in the Soma Alliance is far away from Pompey?"

"It's not very far. Rice City is relatively close to the southern border in the Soma Alliance. If you go all out, you may only need two days to arrive." Yinuo Gaowa said.

It sounds like it's about the same distance as going to St. Louis... Li Cha raised his eyebrows and asked, "If that's the case, why does it take a month or two?"

"This is mainly because the recent situation in the Soma Alliance is a bit turbulent, and our power in the Soma Alliance is very weak. We cannot directly control people and handle affairs. When encountering such a situation, we can only wait patiently for the situation to improve before dealing with it. , so it's a waste of time." Yinuo Gaowa spread her hands and said.

Looking at Li Cha's frown, he thought for a while and then suggested: "Of course, if you are really in a hurry, Wizard Li Cha, you can also leave Pompey and go to Rice to deal with it in person. Less. Just be careful, don’t go away forever and stay outside for more than a year-really, you have to register with me and go through the formalities of handling the residence.”

"Is that so?" Li Cha nodded.

…

Not long after, Richard returned to the Garden of Eden.

Sitting in front of the circular experimental table in the main laboratory, Li Cha tapped his fingers on the table lightly, making a rhythmic "tattling" sound, thinking about Yinuo Gaowa's proposal at the business point just now.

He agrees with Yinuo Gaowa's proposal. After all, the research and manufacturing plan for nuclear weapons has reached this point, and everything is almost ready, and it is only a matter of time. We must not postpone it for a month or two because of a small problem due to lack of materials.

When he came to Pompeii, he considered all aspects~IndoMTL.com~He has not forgotten: his true identity may be exposed at any time. Nuclear weapons research, build programs, and walk away from the danger.

In this case, he must go to Rice once, and the sooner the better.

Thinking of this, Li Cha stepped out of the laboratory without hesitation.

Soon, he found Pandora in the open space in front of the main laboratory, and after briefly explaining what he was about to leave, he handed a crystal ball into her hand.

"I will leave this time, at most a few days, and I will get back as soon as possible." Li Cha warned, "And before I come back, Eden must continue to absorb energy, produce and reserve energy as much as possible." Nuclear materials, so you can’t move it casually. During the process, you have to look after your home, especially the tree in the room. Although I think the chance of him causing trouble is already very low, it is still a hidden danger after all and cannot be underestimated.

Once he really causes trouble, don't be polite, just teach him a lesson. If the situation is critical, please contact me through this crystal ball, and I will drop everything and come back. I have taught you how to use the crystal ball before, remember? "

"Of course." Pandora put away the crystal ball and nodded vigorously, and replied with piercing eyes, "Don't worry, everything will be fine. In fact, it's fine if that tree really caused trouble. I haven't fought for a long time. , just want to make a move."

"Ha." Li Cha couldn't help laughing, thought of something, and asked aloud, "Speaking of which, you won't wait until I'm gone, you deliberately let that tree cause trouble, and then teach you a lesson, right?"

"Is it okay?" Pandora raised her voice slightly, a little pleasantly surprised, and her eyes shone brightly.
