This approach can't continue indefinitely; even our clansmen's planting speed can't keep up with Haru's expansion speed.

Not all the reclaimed land is currently covered with soil formed by the accumulation of protozoa; large areas still have gray-white concrete surfaces.

To ensure everyone can coordinate their work effectively, I've called Haru back from the front lines. We can't expand our territory any further; the increased distance has already caused problems with our food supply.

What Haru can do now is to cut down a large amount of Protoporphyra, fill the empty spaces, and then start planting crops together.

The easiest way to cut down Protoporphyra is to find the nearest location. Those mountains that are not covered by concrete and still have a large amount of Protoporphyra naturally become Haru's targets for logging.

These protozoanths are being cut down by Haru at an alarming rate every day, but in less than two days, huge protozoanths will grow back in the cut areas.

Thus, Haru's daily task changed from constantly expanding the land to endlessly cutting down and transporting Protozoa.

Thanks to Haruz's tireless efforts, the soil accumulated by Protoporphyra algae on those gray-white concrete surfaces is growing rapidly at a visible rate.

The warm and humid tropical climate, coupled with the high carbon dioxide content in the air, provides ample gaseous fertilizer for those crops.

Potatoes and similar crops are among the fastest-growing, almost doubling in size every few months. The planting of potatoes and cassava continues unabated, proceeding in a massive, unstoppable manner.

For the next six months, apart from a few Haru who were responsible for mining ore in the quarry area, the Haru on both sides of the river continued to cut down Protoporphyra to ferment the soil for planting crops.

Haru also knew that only when there was enough food for everyone and the rear area was kept running could they reach further places to cultivate land.

Therefore, even with some tedious planting tasks, Haru still works very seriously. Food is a very important thing to them, and they are very certain of that.

Just a few months ago, it was a concrete surface typical of urban landscape, but in just a few months, it has almost turned into a primeval jungle.

However, there isn't a single weed or shrub growing on it; right now, it's only covered with the crops we've planted.

With no other plants competing with them for sunlight and nutrients, they can grow freely on the land.

These crops can be said to have reached the pinnacle of the plant kingdom; they are now the masters of this land, possessing the power to allocate all sunlight and nutrients.

The food did not disappoint me; a great harvest of food was achieved in the second half of the year.

Harvesting these potatoes and cassava has been quite a headache for me. Previously, I'd been using cellars or similar places to temporarily store this food.

But there's just too much food now. Our base's cellars aren't nearly enough. Tens of thousands of tons of food is no small amount to be taken lightly.

If not handled properly, they could break down in large numbers at any time, and all our efforts would be wasted.

It's true that you worry whether you have food or not.

Previously, the lack of food was due to concerns about not having enough for everyone to eat later; now that there is food, the issue of food storage needs to be considered.

This is the tropics, and the warm, humid climate makes it easy for these crop tubers to rot.

In order to better preserve this hard-won food, I have to squeeze some more brainpower out of myself.

After some design and development, a solar-powered dehydrator for storing grain was completed.

Besides water, the only other thing we can utilize now is solar energy.

Previously, all the tall trees and weeds were wiped out by the Protoplasta, and now we've wiped out the Protoplasta as well.

It can be said that apart from the low-growing crops we plant, there are no plants on the ground that exceed three meters in height.

Without any obstructions to block the sunlight, it became incredibly harsh. Even a white person exposed to this sun would turn into an African chicken in a day.

The principle of a solar-powered dehydrator is very simple; to put it bluntly, it's like a large rectangular shipping container.

At its top layer and on both sides are heat-absorbing covers made of thin copper sheets. Copper has the best thermal conductivity, which is to make the copper covers more effective at absorbing heat.

I deliberately painted all the copper sheets black to better absorb sunlight.

At each end of its rectangle is a large door with air convection holes at the top, allowing free passage.

At the other end is a large exhaust fan wheel, one meter in diameter, fixed to the wooden wall. The fan wheel is still powered by a waterwheel built on the riverbank, which is connected to a belt for driving.

The space here is enormous, exceeding 500 square meters, and there are over 200 shelves inside that can be used to store food for dehydration.

This large dehydrator can hold more than two thousand tons of food at a time for dehydration.

Inside, copper sheets absorb the sun's heat, so the temperature is naturally much higher than outside. However, the highest temperature inside only reaches around fifty degrees Celsius, far from being enough to burn food.

High temperatures cause crops to lose moisture quickly, and the large amount of water vapor that evaporates will then allow a large amount of dry outside air to enter through the air convection holes on the door.

The water vapor inside is drawn out of the dehydrator by a giant fan, keeping the environment inside at a suitable high temperature and dry conditions.

Foods that would normally take a week to dry can be dried to a degree that allows them to be ignited in a single day here.

It took us nearly two months to build this huge processing machine, with one solar-powered dehydrator on this side of the river and one on the opposite bank.

Food harvested in batches can be stored for a much longer time after processing. However, it must be soaked in water before consumption, otherwise it might break your teeth.

To prevent these dry crops from getting damp, we poured molten iron to make steel bars, and then poured concrete to build several large grain silos.

With these supplies in place, I feel more at ease sleeping.

It's not just our population that's growing rapidly; the few dozen wild boars we used to raise are now everywhere.

However, the wild boar population is relatively easy to control; the best way is to eat them. But as the human population increases, the scale of wild boar farming also needs to be expanded.

So, while the housing for people was not yet settled, the large-scale pig farm was already under construction in an orderly manner.

We plan to first establish four aquaculture farms on the other side of the river and one on our side.
