Chapter 1029 Everything Is Ready and only Owes the East Wind

"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, all of which were marked with crosses.

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

The first, listed as rhinestone, 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 regeneration of tungsten The crystallization initiation temperature 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 that's brittle at room temperature, has a modulus about 50 percent higher than steel, and has 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. The important thing is that except for trace radioactive isotopes caused by cosmic rays, natural beryllium is almost completely 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, both materials are important for the manufacture of implosion atomic bombs.

Rhenium could not be found, and he could 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.

However, beryllium cannot be found, so it is a bit difficult 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 and looking up at Yinuo Gaowa, Li Cha asked for confirmation: "Wizard Yinuo Gaowa, the two missing materials on the list, are you really not found at all?"

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

After finishing the words, he searched for 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 this is 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.

I can't directly control people to handle affairs. When encountering such a situation, I can only wait patiently for the situation to improve before dealing with it, so time is a bit wasted. "Yinuo Gaowa spread her hands and said.

Glancing 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. Naturally, it will be much faster. As long as Be careful, don’t just go away and stay outside for more than a year—if that’s the case, you need to register with me and go through the formalities of dealing with 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 gently tapped the table with his fingers, making a rhythmic "tap-tap-tap" sound, thinking about the proposal made by Yinuo Gaowa 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.

He has not forgotten all the aspects he considered when he came to Pompeii: his true identity may be exposed at any time. Pompeii is equivalent to an enemy-occupied area. With the help of Pompeii's resources, he must complete the nuclear weapon research and manufacturing plan as soon as possible, and then Just walk away and get out of this 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. 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 finish my work as soon as possible." Li Cha warned, "Before I come back, Eden will continue to absorb energy, produce and store nuclear materials as much as possible, So you can’t move around casually. During the process, you have to take care of your home, especially the tree in the room. Although I think the chance of him causing trouble is very low, it is still a hidden danger 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. Move your hands."

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

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