After the orders were given.

Seka and Fan Yunfeng, the leader of the logistics team of this secret base, went to inspect the storage and production of the base.

The construction of this base has been ongoing, and after nearly two years of expansion, it has become well-equipped and accessible in all directions.

Inside this base, there are two places in the most central area.

At this time, Seka and Fan Yunfeng were inspecting one of the core areas.

This is a single-story area of 5,000 square meters, divided into 4 floors, in which a large number of cultivation pools are arranged, the genetic recombination medium in the cultivation tank, and the biological material medium secretly transported from Honsavady.

The lowest layer is the nutrient absorption tank, which can use animal excrement and plants as nutrients, and then supply nutrients and energy to the cultivation ponds in the upper layers.

As for some other metal powders, inorganic salts, etc., they can also be collected nearby through bio-enrichment of lichens and mushrooms.

At present, this material and parts cultivation area, with sufficient raw materials, can produce most of the alloys, non-metallic materials, biological materials, and parts with less complex structures.

The production capacity is about 1200~1500 tons per month.

For example, firearms, small hardware, glass products, generators, pure mechanical equipment, crystal sponges, and rubber products in the base can all be produced here.

It is precisely because of this highly self-sustaining model that Tianzhu did not realize that such a powerful force would be hidden in such a remote mountain village.

After all, there is no need to import a large number of equipment and instruments from the outside world, which is the biggest advantage.

Even inside the base, a mini-chemical plant has been built through the supply of a small number of precision parts and biocomputers in Honsavady, which can produce more than 200 tons of TNT, or other chemicals, every month.

After inspecting the parts production area and the chemical production area, Serka and Fan Yunfeng went to another core area.

The other core area is the "farm" built deep in the ground of a mountain.

As a highly self-sustaining base, the food supply must be self-sufficient.

Although new humans can add an external auxiliary digestive sac, and then directly feed the auxiliary digestive sac with grass, trees, poisonous insects, carrion, cow dung, etc., and then obtain energy and nutrients from it, so as to maintain the normal life needs of the human body.

Even in more extreme environments, "plant exocarapaces" and "hibernation sacs" can be used.

Plant exomorphic armor is actually a variant of exoskeleton armor, its function is more focused on wilderness survival, doomsday survival, through the surface of the genetic recombination of plant cells, directly photosynthesis and absorption of nutrients in the soil, air and water body, so as to maintain the user's life.

The hibernation sac is used in special environments, such as deserts, polar ice fields, and chemically polluted areas, and the body is difficult to support and escape from these places, so let this sac wrap the body and enter a state of suspended animation.

At present, hibernation support sacs can maintain dormancy for up to about 120 days, and some new humans who perform special tasks need this kind of thing.

The base where Seka is located is equipped with auxiliary digestive sacs, plant exonails, and hibernation support sacs.

However, these devices are only considered in extreme cases.

When you are not exhausted, some normal food is still very necessary.

Hence the "farm" came into being.

Due to the underground environment, natural light is basically not considered, artificial light requires a lot of energy, and the photosynthesis energy efficiency of plants is actually not high.

Genetically recombinant organisms, such as luminescent lichens, are not suitable as a light source for underground farms.

After many studies and experiments, Li Qingye finally found a technology that can make plants grow quickly without sunlight, and increase the rate of organic matter generation in plants by more than ten times.

Specifically, a composite electrocatalytic system is used to convert carbon dioxide and water into acetate, which can then be directly absorbed by the plant organism, thus bypassing the photosynthesis phase.

At present, this technology has been successfully applied to some genetically recombinant plants.

And this technology is also at the heart of underground farms.

In this way, a large number of planting rooms have been built in the farms in the base, which can produce cucumbers, tomatoes, soybeans, sweet potatoes, potatoes, corn, eggplants, pumpkins, winter melons, peppers, green peppers, strawberries, watermelons, and sugar cane.

Serka picked a small cucumber, wiped it casually, and nibbled on it: "Can the production of the farm completely replace the surface farmland now?" ”

"If you just maintain the current population, there is no problem." Fan Yunfeng replied.

Seka frowned, the current population of the base is 793 people.

But that's just for now, and as the plan unfolds, the population of this base is sure to skyrocket.

He continued: "How many people can be supplied by the limit capacity? ”

"3,000 people is basically the limit of sustainability."

"Is there a way to expand?"

Fan Yunfeng thought for a while: "We actually don't lack underground space, after all, we can arrange a few more floors, and the key issue now is power supply." ”

"Electricity ......" Sekka also felt very tricky when he heard this question.

At present, the electricity used by the base is actually more than a dozen small gas turbine generator sets, with a total power of 1,400 kilowatts.

The source of fuel is methane fermenters, which rely on human and animal excrement on the one hand, and plant raw materials such as straw and dead branches and leaves collected on the other.

The power generation of 1400 kilowatts is already the limit of this base.

Even with gas turbines and generator sets, there is not enough biomass to produce methane.

After thinking for a moment, Sekka asked, "Is it possible to develop shale oil and shale gas underground?" ”

"Huh...... Unfortunately, there isn't much oily shale in the rock formations around Shillong. Fan Yunfeng spread his hands.

The energy problem at the Shillong base made Sekka scratch his head.

Now there are only more than 700 people, naturally there is no big problem, once the population increases, the demand for energy will definitely skyrocket.

The problem is that according to the estimation of the headquarters, the Tianzhu people will not give up on the Assamese states, and this place will definitely become a flesh millstone.

Thermal power plants, solar farms, wind farms, hydroelectric power stations, etc., which are too obvious on the ground, will definitely be targeted.

Even if it's made, it's just a target.

Therefore, it is necessary to find a way to solve the energy problem of the base, and only by solving the energy problem will the population capacity limit here be increased.

Although Serka considers himself a new human being who transcends race.

But ordinary people are innocent after all, and if he can save more ordinary people, he is still willing to try.

Suddenly, he had a flash of inspiration, opened the tablet he was carrying, called up the three-dimensional topographic map of the surroundings, and soon he found what he was looking for.

"Old Fan, do you think this will work?" He pointed to a nearby river valley with a drop of more than 80 meters: "We can use artificial debris flow technology to artificially block this valley and form a dammed lake." ”

"A dammed lake?" Fan Yunfeng looked at the three-dimensional topographic map: "You plan to build a hydropower station?" But it's all too obvious. ”

"Nope! We can use rapid excavation technology to create an artificial underground river, and then set up the hydropower station in the mountain. Serka said as he carved out an underground river hidden in the mountain between the two drops.

Fan Yunfeng recalculated and found that this plan is indeed feasible, with the flow of this river, it can probably push the installed capacity of 10~20 megawatts of water turbines.

This power generation is almost 10 times that of the base.
