Biotechnology does have its advantages. In essence, using living organisms for industrial production is equivalent to using Neumann machines. These devices can self-replicate, so that after a product is finalized, it can be produced in large quantities like mushrooms after a rain.

Production.

And they don't need any chemical energy, they only need to provide a large amount of organic matter. Their physical and mental needs can be completely met by planting grass. By cultivating corresponding plants that can absorb sunlight, they can quickly convert solar energy into the energy they need.

Even though Sylva has been heavily surrounded, the empire still does not dare to tighten the encirclement too tightly. Within an area of ​​nearly 100 kilometers in diameter, there are more than 7,000 square kilometers of land, at least half of which is not effectively controlled by the infected.

A large amount of energy can be provided underground through plants that can efficiently absorb solar energy.

Even if these energy sources are still somewhat insufficient, a large amount of high-strength organic materials have also alleviated the threat of insufficient metal minerals for the infected.

Silva began an unprecedented rapid development and prepared to try to ignite a nuclear reactor. This was the former industrial center of the Tiandou Empire. There were already abandoned nuclear reaction facilities and nuclear materials on the surface that were too late to clean up.

The concentration may not be enough for making nuclear bombs, but after refining, it can be used to heat the reactor. It has not been attempted before because there is no suitable material on hand.

The scarcity of metal minerals makes it difficult for them to synthesize high-strength alloys themselves. In this case, if they continue to rely on metal materials, it is almost impossible for them to increase the strength of the material to a level sufficient to carry nuclear reactions.

It wasn't until they changed the technology tree and started experimenting with organic materials that they gradually figured out the way to create materials with sufficient strength. It wouldn't take long for them to successfully ignite a fire.

The large amount of nuclear fuel left on the surface here can provide them with energy consumption for hundreds of years. Together with the absorption of surface light energy, their energy will no longer be scarce, and the development speed of science and technology in the future will reach an incredible level.

Currently, this incredible underground city has become deeper and deeper, and also larger and larger.

A large number of underground buildings are made of biological materials, which can be seen on construction sites. The buildings seem to grow quickly. But if you think that the wriggling building walls are extremely soft, you are totally wrong.

.

After the cells grow and become established, they quickly lose activity. The cell membrane ruptures, and the organic matter contained inside quickly reacts with the cell wall, forming a tight support like a crystal lattice between each cell. The seemingly soft building materials will quickly harden, with comparable strength.

Concrete is even more outrageous.

Watching the carloads of light yellow grass leaves being dried and fed into the filling port, and then the building growing rapidly as it continues to swallow up organic matter, it is really an indescribable feeling. Especially in the entire building.

After they are all built, they will be attached to the surface of the building like blood vessels and used to transport mechanical things. They will collectively necrotic and fall off, just like some huge creature with muscle necrosis and ulceration. It looks very ugly. This is the first time I saw it.

Such a scene may even leave a psychological shadow.

However, the adaptability of intelligent creatures is still very strong. After the initial discomfort, the infected people gradually adapted to their own industrial system with a unique style and a hint of Cthulhu style, and even occasionally tried to make some things in their own homes.

Biochemical eyeball skewers are an authentic Kejia dish, Cthulhu's Kebab.

Excavation of underground space was originally a very troublesome matter. The infected lacked high-strength metal and found it difficult to build their own shield machines.

In the past, excavations were forcibly carried out with the help of the powerful strength and skills of individuals. Later, after encountering the encirclement and suppression troops of the empire, the blades of several shield machines were replaced. However, although those things are strong, they are consumables after all.

The excavation process will inevitably cause wear and tear. As a result, the seized blades were all broken after being used a few times after assembly.

This also limited Silva's expansion for a time. After all, personal power is limited. Even if you practice earth-attribute skills, the most you can do is drill underground to look like a research institute. What they want to build is...

A city with hundreds of thousands of people may have to accommodate millions of people in the future. This cannot be done by a few people alone, nor can there be so many people. They specialize in practicing the earth attribute to open up underground space.

All aspects of a city require manpower to maintain. Those responsible for the excavation project can only have a few thousand people at most. If the excavation is purely based on manpower, who knows when they will be able to expand the size of the city to a million people.

Okay, later on, biochemical technology gradually developed, and the scientific research department developed giant digging worms.

They have sharp mouthparts that can easily cut through hard rock formations. They can also swallow gravel and soil and rely on the powerful muscles in their bodies to compress them. They also produce high-density columns that can be used as building materials. People from the engineering team jokingly call these

The hard building material is shit alloy, which means shit as hard as alloy, which is quite appropriate in a sense.

These high-density building materials will be transported away. As the support pillars between the underground layers, a worm has a total of one large and eighteen small, a total of nineteen esophagus, and the mouthparts will chop and swallow the rocks. It will be eaten by the mouth.

Peristalsis. Different hardnesses are distinguished. The harder ones will be compressed into the small esophagus. With compression and peristalsis, they will be spirally squeezed into the thicker esophagus.

After these harder rocks are compressed, they will greatly enhance the strength of the stone pillars like steel reinforced concrete, making these feces alloys extremely strong and able to support the huge pressure between huge soil layers.

At present, the biggest goal of these worms is to dig into the asthenosphere underground and use the temperature difference between the magma and the surface to establish geothermal power generation facilities to provide large amounts of geothermal energy to cities.

Before the nuclear reactor is ignited, this will be the city's most important energy source. Even after it is ignited, it will still become an important energy supplement. After all, no matter how capable the empire is, it will not be possible to dig into the asthenosphere and then encircle it entirely.

, to prevent magma from flowing in their direction. This is currently the safest and most reliable source of energy that Silva can find.

But they didn't expect that this excavation would bring them unexpected joy. The former Tulip Man discovered a prosperous atmosphere of atmospheric creatures in the sky, and there were also prosperous biological groups in the underground where they had never set foot.
