"Thank you." Richard thanked him, took the list handed over by Inogova, glanced at it a few times, and soon saw several materials that had not been collected yet, all with crosses on them.
What I haven't found is, to be precise, there are two types.
The first type, the name on the list is rhinestone, but it is actually rhenium.
This is a silver-white metal that is very hard, wear-resistant, corrosion-resistant, and insoluble in hydrochloric acid and hydrofluoric acid. This metal has an excellent feature, that is, it is heat-resistant. Its melting point is 3180°C, ranking third among metals, and its boiling point is as high as 5627°C, the highest among all metals.
This metal also has a "rhenium effect". When 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 tungsten more durable. The crystallization onset temperature increases by 300℃-500℃. It is precisely in this way that after the implosion nuclear weapon ignites the high explosive, the rhenium-tungsten alloy can squeeze the nuclear raw materials under high temperature and high pressure without being affected.
The second type, the name on the list is sweet green stone, is actually beryllium.
This is a gray metal that is brittle at room temperature. Its elastic modulus is about 50% higher than steel, but its density is lower, so the speed of sound is very high. Under standard temperature and pressure, the speed of sound propagation in it is about 12.9 km/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 amounts of radioactive isotopes caused by cosmic rays, natural beryllium is almost entirely composed of beryllium-9 isotopes with a nuclear spin of 3/2. This results in its relatively large cross-section for high-energy neutrons, and its cross-section for neutrons with energy higher than 10keV can reach 6 targets, which can quickly reduce the neutron thermal energy to below 0.03eV. It is an excellent neutron reflector and neutron Reducer.
To put it simply, using it as a reflective layer can limit the activity of neutrons within a certain range, allowing a continuous nuclear chain reaction to proceed, which will help increase the power of atomic bombs.
At the same time, beryllium will release neutrons when deuterons and protons collide, so it can become a neutron source under certain conditions to stimulate the nuclear explosion of an atomic bomb.
In short, both materials are important for the manufacture of implosion atomic bombs.
He could still understand that rhenium could not be found.
After all, this metal is relatively rare and was only discovered very late on the earth. If he really can't find it, he can try to use other materials to replace it.
But it’s a bit hard to accept that beryllium can’t be found.
Beryllium is much more common than rhenium, and is found in certain types of emeralds, among other things.
Putting down the list and looking up at Inogova, Richard asked with confirmation: "Wizard Inogova, are you really not able to find the two missing materials on the list?"
"Is this..." Inogova hesitated, thought for a moment and said, "Wait a moment."
After saying this, I started searching for several piles of information on the table. After searching for a few minutes this time, I finally found a new document. After reading the above content carefully, he looked over and said: "Wizard Richard, according to the report handed in, part of the sweet green stone has been found, and some clues have been found for another type of rhinestone, all of which are concentrated in the search. In a mining city called Les in the Ma Union. However, it may take a month or two to collect the materials to the amount you require and transport them back, so the current status of these two materials on the list , it’s still vacant.”
After hearing this, Richard frowned slightly and asked, "Is the Soma Alliance's Les City far away from Pompeii?"
"It's not very far. Rice City is relatively close to the southern border in the Soma Alliance. If you go all out, it may only take two days to arrive." Inogova said.
It sounds like this is about the same distance as going to St. Louis... Richard raised his eyebrows and asked, "If that's the case, why does it take another month or two?"
"This is mainly because the situation in the Soma Alliance has been a bit turbulent recently, and our power in the Soma Alliance is very weak. We cannot directly control people to do things. When encountering this kind of situation, we can only wait patiently for the situation to improve before dealing with it, so time There's some waste there." Inogova said, spreading her hands.
Glancing at Richard's frown, he thought for a while and then suggested: "Of course, Wizard Richard, if you are really in a hurry, you can leave Pompeii and go to Les to handle it in person. It will naturally be a lot faster. As long as you are really anxious, you can leave Pompeii and go to Les to handle it in person. Be careful, don’t just leave and never come back and stay out for more than a year—in that case, you have to register with me and complete the procedures for dealing with your residence.”
"Is that so?" Richard nodded.
…
Not long after, Richard returned to the Garden of Eden.
Sitting in front of the circular experimental table in the main laboratory, Richard tapped his fingers lightly on the table, making a rhythmic "tap-tat-tat" sound, thinking about Inogova's proposal at the business point just now.
He quite agreed with Inogova's proposal. After all, the research and manufacturing plan for nuclear weapons has now reached this stage. Everything is almost ready and all we need is east wind. We must not delay it for a month or two just because of a small problem of lack of materials.
He has not forgotten all the aspects he considered when he first came to Pompeii: his true identity may be exposed at any time. Being in Pompeii is equivalent to enemy-occupied territory. He must use Pompeo's resources to complete the nuclear weapons research and manufacturing plan as soon as possible, and then Just walk away and get rid of this danger.
In this case, he must go to Les, and the sooner the better.
Thinking of this, Richard walked out of the laboratory without hesitation.
Soon, he found Pandora in the open space in front of the main laboratory. After briefly telling her about his departure, he handed a crystal ball into her hand.
"I will leave for a few days at most, and I will finish my work and come back as soon as possible." Richard warned, "Before I come back, the Garden of Eden must continue to absorb energy and produce and reserve nuclear materials as much as possible. So you can't move it casually. During the process, you have to watch your home, especially the tree in the room. Although I think the chance of him causing trouble is very low, after all, it is still a hidden danger and cannot be underestimated.
Once he really causes trouble, don't be polite and just teach him a lesson. If the situation is critical, just contact me through this crystal ball, and I will drop everything and rush back. I have taught you how to use the crystal ball before, remember? "
"Of course." Pandora put away the crystal ball and nodded vigorously, replying with bright eyes, "Don't worry, everything will be fine. In fact, it doesn't matter if that tree really causes trouble, I haven't had a fight in a long time, and I was just thinking Move your hands."
"Ha." Richard couldn't help but smile, thought of something, and asked aloud, "Speaking of which, you won't wait until I leave, you deliberately let that tree cause trouble, and then teach you a lesson, right?"
"Is it okay?" Pandora's voice was slightly higher, a little surprised, and her eyes were shining.
