Homo sapiens.

Under the leadership of base chief Wu Hu, a group of people entered a mine near Heihu Town.

I chose this place because of the concealment and the convenience of water transportation on the one hand, and the mine on the other.

This is a small lead-zinc mine, and many underground mines were dug by the previous mine owner.

After the second transformation, all the mine tunnels were reinforced, expanded, and modified, and became the current underground base.

Moreover, the second phase of the base project is also being carried out in secret.

Li Qingye took the elevator shaft transformed from the mine and reached the 27 meters underground. If a part of the mountain is added, the depth of a part of this area can reach thousands of meters.

The nuclear facilities are set up under the cover of those mountains.

"We have already transferred some of the rough materials here, and currently there are 1200 tons of rough materials in reserve here." Kevin introduced in a low voice.

At the bottom of the elevator shaft, after taking the elevator, there is a small underground station, where trams are used as a means of transportation.

Wu Hu hurriedly opened the door of the car: "Boss, let's get in the car!"

Soon the tram started slowly and drove towards the depths of the base.

However, the tram did not directly enter the nuclear test area and the crude material storage area. After all, these things have certain risks.

Wu Hu took them into the nuclear test area after changing into full-coverage biological protective suits in the safe area.

A group of researchers, also wearing full-body protective suits and special resin transparent space helmets, were in front of a small centrifuge.

Wu Hu called the head of the researcher, Dr. Reeves, who was a former researcher at the Luzon Nuclear Power Plant and one of the few scholars in Luzon who studied nuclear physics. He was secretly sent here early this year through suspended animation and a facelift.

Levi's actually met Li Qingye in Luzon, and he said helplessly, "Li, this small centrifuge can't separate uranium-235 at all. You should understand the danger of such a thing!"

"Don't worry! I will solve the problem of uranium enrichment." Li Qingye replied confidently.

"You can solve it? Li, although I admit that you are a top biologist, but this is nuclear physics." Levi's expression was suspicious.

Li Qingye shrugged, then turned his head and instructed Wu Hu: "Take the item No. 983 that was delivered earlier, and bring it to the special biology laboratory here."

"Yes, boss."

After a while, in the special biological laboratory.

What Li Qingye wanted was already placed in front of everyone.

He opened the suitcase, which contained rows and rows of storage test tubes in which special frozen fungal spores were stored, and took out one of them.

Insert into one of the large barrel Petri dishes.

After adding various pheromones and hormones, as well as a steady stream of nutrient solutions, and adjusting the temperature, the fungus quickly grew in the petri dish.

After an hour of rapid growth, Li Qingye mixed one hundred kilograms of uranium-containing powder and nutrient paste together.

Finally, the fungi in the petri dish were poured into the uranium-containing nutrient paste.

"Let's go!"

"Is that all right?" Levi's was at a loss.

Li Qingye replied confidently: "Don't underestimate the adaptability and possibility of living things. You must know that the area around the Chernobyl reactor is now full of fungi."

Levi's, who was skeptical, muttered to himself: "Can biotechnology really complete uranium enrichment?"

"Tomorrow you'll find out."

The next day, early in the morning.

Levi's couldn't wait to come over, obviously he also wanted to know how effective the bio-enrichment technology was.

Open the row of lead room cultivation ponds, and there is a large reddish-brown fungal aggregate floating on the surface of the cultivation pond at this time, which is somewhat similar to the appearance of cyanobacteria after eutrophication.

"Remove the bacteria on the surface, and then dry the sludge at the bottom of the cultivation pond."

"Yes."

The bacteria floating on the surface are removed, and then the sludge at the bottom of the pool is filtered and dried, turning into hundreds of kilograms of mud.

Levi's led people to measure the uranium-235 content of the mud.

After more than five hours of intensive testing, the content of uranium 235 in the mud finally came out, and its concentration reached about 7.2% to 8.3%.

Obviously, this concentration made Levi's feel unbelievable, which is equivalent to being purified hundreds of times. He said excitedly:

"Lee, you are such a genius."

But Li Qingye felt a little dissatisfied:

"This technology is not yet perfect. Currently, uranium-enriched bacteria cannot purify uranium-235 at one time. It must undergo 15 repeated absorptions before it can extract uranium-90 with a concentration of more than 235%."

"And among the uranium elements absorbed by uranium-enriching bacteria, there is still a small part of uranium-238 remaining, and these wastes must be processed again."

hehe!Levi was speechless.

In his opinion, this technology is already very powerful. Even if it needs to be absorbed repeatedly 15 times, it is faster and cheaper than the centrifuge separation method, and it can even be said to be cheap.

It should be known that the bioconcentration method only needs simple cultivation equipment, strains, nutrients, hormones and pheromones.

The cost of these things is not high for Homo sapiens.

Levi's roughly estimated that according to the current data, the cost of producing one kilogram of uranium-90 with a concentration of 235% would not exceed 5000 gold dollars.

This cost is simply a centrifuge separation method.

Chapter 141 Arrow and Bow

Levi's directly ignored Li Qingye's Versailles, but looked at the huge pile of sludge in front of him, his eyes filled with excitement.

100 kg of uranium crude material contains about 0.8 kg of uranium element. After removing part of uranium 238 by uranium-enriching bacteria, only 75 grams of uranium element are left.

Among the 75 grams of uranium, the content of uranium 235 is about 7.5%, that is, about 5.6 grams, and the rest is uranium 238.

Although this concentration is not high, in the eyes of Levi, who majored in nuclear physics, this concentration is simply breaking through the sky.

After all, the concentration of uranium-235 in current civilian-level nuclear reactors is generally below 5%.

In other words, after the mud in front of us is extracted and processed, it can be directly used as nuclear fuel for nuclear reactors.

This is why Levi's marvels at this technology, which is cheap, efficient, and very concealed.

Using this technology, even a small country like Hongshawadi with very poor supporting facilities can produce high-concentration weapon-grade uranium-235.

In fact, the design principles of the atomic bomb can be found on many nuclear physics academic websites. Except for the hydrogen bomb, which is partially blocked, the principles of other nuclear reactions are not difficult to find.

Levi's can even design a hydrogen bomb.

But that's not the point.

The key to nuclear weapons actually lies in uranium enrichment technology.

The current relatively efficient industrial uranium enrichment technology is the centrifugal separation method. This technology has a huge threshold, not only the investment is not small, but also the movement is not small.

The great powers could quickly discover why Persia and North Korea conducted nuclear experiments. The reason is that the centrifugal separation method must use a large number of multi-stage ultra-high-speed centrifuges, which not only occupy a very large area, but also consume an astonishing amount of power.

As long as satellite remote sensing is used, large-scale uranium enrichment facilities can be found.

As for building facilities on the mountain or underground, this plan is obviously not feasible, mainly because the scale is too large, such underground facilities cannot be afforded by ordinary small countries, and those who are capable of building underground facilities do not need to be sneaky.

Levi's is very excited now. He is not that kind of pacifist. He was blacklisted by Western academic institutions in Luzon before because of his nuclear speeches.

His ideas are very radical. He believes that small countries can resist the bullying of the big powers only if they have nuclear weapons.

When Li Qingye secretly invited him, this guy threw himself into his arms directly.

For his own dream, he divorced his first wife, then feigned death and left, and came to a small valley in Hongshawadi.

Today, Levi's finally saw hope.

The meeting room of the base.

Li Qingye, Kevin, Wu Hu, Levi's and others gathered together.

Kevin calculated the current uranium raw material reserves: "According to the current uranium crude material reserves, we can extract 170 kg of uranium-235 from it.

"Dr. Levi, how many atomic bombs can be produced with 170 kilograms of uranium-235?" Li Qingye asked.

Levi's thought for a while: "If relatively primitive and mature technology is used, 50 kilograms of uranium-235 can produce a 30-equivalent atomic bomb, and 170 kilograms can produce three."

After listening to this data, Li Qingye thought for a while, and then made a decision: "OK, I understand, then use the mature old-fashioned technology to manufacture three 30-ton atomic bombs first."

"Li, how do we experiment? After all, I have only studied the theoretical framework of this thing, and it is difficult to guarantee that there will be no problems in practical application." Reeves reminded with some hesitation.

Li Qingye shook his head: "In a short period of time, the live ammunition test will definitely not work. How about using laser focusing experiments and graphite slow neutron reactors?"

"Laser focusing? This can solve part of the problem. I am also working on a graphite slow neutron reactor, but there may be some errors compared to the live ammunition detonation test." Levi said helplessly.

Li Qingye was not disappointed about this: "It's good to be able to test the data. In a short period of time, we have no way to confront the foreign powers head-on. We need to store at least 100 atomic bombs or develop a hydrogen bomb before we can conduct live bomb tests."

"Speaking of hydrogen bombs, can our bioconcentration extract heavy water?" asked Levi's.

Li Qingye rubbed his chin: "In the process of developing uranium-enriching bacteria this time, I discovered more than a dozen special gene sequences, which can effectively distinguish the small differences in isotopes. As long as I adjust the genes next and test for a while, It should be possible to screen out some fungi that are suitable for enriching deuterium."

"Then I suggest building a batch of deuterium enrichment factories. Anyway, now we already have nuclear fission uranium bombs, which can be used as atomic triggers for nuclear fusion."

Li Qingye turned his head: "Kevin, you are responsible for the implementation. Using the production of seaweed and methane as an excuse, open a batch of deuterium enrichment factories."

"Yes, boss." Kevin nodded.

after the meeting.

Li Qingye still stayed in the base of Black Tiger Canyon, he was thinking about another problem.

Then there is the issue of vehicles.

To constitute nuclear deterrence, it is not enough to have nuclear bombs alone, but also to have sufficiently powerful long-range delivery vehicles.

In fact, Homo sapiens is already developing this aspect.

For example, the Typhoon series of cruise missiles being developed by the previous subsidiary, Flying Fish.

Of course, if possible, Li Qingye also hopes that Homo sapiens will have an official intercontinental ballistic missile.

He glanced at the various technologies on the bio-laptop, hoping to integrate the technology that can be applied to intercontinental ballistic missiles among the technologies currently owned by Homo Sapiens.

First of all, there is no need to worry too much about nuclear warheads. Although the nuclear fuel utilization rate of nuclear bombs produced by old-fashioned technology is lower than that of modern and latest technology, the deterrence is stronger.

After all, the older the craft, the more serious the residue of radioactive substances after detonation. To a certain extent, it is also an advantage that makes opponents throw a mouse.

Now the key is the vehicle itself.

"Maybe..." After seeing the crystal sponge technology, he suddenly thought of a plan.

Modern intercontinental missiles are mainly divided into two types of fuel, one is a solid fuel type, and the other is a liquid fuel type that can be stored at room temperature.

Usually solid fuels occupy the vast majority, while liquid fuels are used in high-thrust space launch vehicles.

The reason for this is that liquid fuels are either not suitable for long-term storage or are highly toxic.

However, Homo sapiens' crystal sponge technology can store methane, and after storage, it can remain solid at normal temperature and pressure, and the storage time is very long.

Compared with the missiles or launch vehicles currently used by various countries, if crystal sponge is used as a fuel storage tank, the requirements for its production process and supporting facilities will be greatly reduced.

The more Li Qingye thought about it, the more he felt that this direction was good.

He quickly asked the Hongshawadi branch to find a small basin in the mountains in the northern Kachin State as a research and development base for methane rocket engines.

Of course, this base can also undertake the future aerospace industry of Homo sapiens.

In the near future, Li Qingye will stay in Hongshawadi. On the one hand, it is to adjust the layout of various industries, and the rocket engine, missile, and aerospace industries are the key.

On the other hand, it is also to inspect Hongshawadi and see the development of this branch.

After receiving his instructions, the Honshawadi branch also quickly implemented them.

This mode of operation is also one of the current advantages of Homo Sapiens. There are no people who are wrangling or enriching their own pockets, and the utilization rate of various resources has skyrocketed.

Chapter 142 Conference

Li Qingye stayed in Black Tiger Canyon for more than a week, then disguised himself as another identity, and went directly to Binmana.

As the capital of Hongsawady, Pinchana is currently developing well.

Originally, there was no direct connection between Kayah State and Pyinmana District by road, railway or waterway.

However, Qingye Group built two expressways for the two places during the wave of infrastructure construction at the end of last year.

At present, Li Qingye's convoy is on the expressway from Leigu, the capital of Kayah State, to Pyinmana. In fact, the distance between the two is very close, and the straight-line distance is only about 105 kilometers.
