My heart was pounding; this was a matter of life and death for us. If we succeeded, we could find a way to temporarily stop the growth of *Prorocentrum spp.*

I first touched the poured concrete with my hand. At this time, the surface of the concrete was dry and white, and it felt very cool to the touch. Even if I pressed hard on it with my finger, I couldn't make a mark.

So I stood directly on the concrete and stomped my feet hard. It was still a grayish-white mess, with no signs of damage except for some dirt and dust.

"It's done! Now we can begin to deal with those Protoplastae."

I shouted excitedly, "Although we can't completely wipe out the Protozoa, at least we can reclaim and utilize some of our land."

Haru and our people were delighted to hear this, and immediately a large number of people rushed onto the dry concrete ground to experience what made it different.

They discovered that this thing was indeed as hard as a rock; even poking it with a stick couldn't leave a mark on it.

What's even more surprising is that there are no white mycelia on it, and the fruiting bodies of those Protoplastia can no longer grow.

This concrete-paved ground is now considered our first victory, and it's truly usable land.

The Haru people were overjoyed, thinking it was a magical thing. They believed that if all the land were covered with it, everyone would no longer have to struggle for living space.

Haru secretly resolved to produce more of that cement and turn all the ground into stone.

A major project is about to begin, and all the Haru and our people are working hard to reclaim our land.

Now their task is to develop infrastructure and pave large areas of roads. Although these reclaimed lands cannot be used to grow crops directly, weeds and dead wood can be used to create new soil.

As long as the new soil on the concrete doesn't come into direct contact with the protozoa, there won't be any problems, and food can still be grown for everyone to eat.

However, using weeds and dead wood to pile up soil is too slow. I thought about it, since those Protozoa are also carbon-based life forms, they can also be used to create fertile soil.

However, before proceeding, it's best to sterilize the *Protoplastrus* at high temperatures as a precaution. This will kill all the mycelia, preventing them from germinating and causing infection.

The method is quite simple: a large number of Protozoa fruiting bodies have been dried in the sun. These dried Protozoa can be ignited like firewood.

Simply cut fresh, water-containing Protoplastrus orchids into small pieces and place them on top of burning Protoplastrus orchids. By the time the lower Protoplastrus orchids turn to ash, the fresh Protoplastrus orchids on top will have already been completely killed by the high temperature.

Then mix them together and pile them up to ferment for a month. After that, put earthworms on top to further decompose the Protoplast into usable fertile soil.

Beans are boiled to make soup, the dregs are strained to make broth; the stalks burn beneath the pot, the beans weep within. We are born of the same root, why must we so cruelly harm each other…

Using Protoplastrus orientalis to destroy itself and then recycling it is a way of making the most of resources and following the natural cycle.

The problem of land scarcity has suddenly disappeared thanks to real estate development, and everyone is now more motivated than before.

Before paving the road, the protozoan algae need to be cut down. In order to accumulate more high-quality soil, Haru is always the first to get up and cut down the protozoan algae.

Moreover, they get carried away with any kind of physical labor, and once they start cutting, the entire Prosocephalae within a radius of several kilometers will suffer.

However, our cement roads simply cannot keep up with Haru's logging speed. Sometimes, the regrown Proterophytes need to be cut down a second time, and Haru, without saying a word, will cut them down again.

Their theory is that since they're idle anyway, exercising more is much more fulfilling than staying at home.

Despite the large-scale logging of Prosopa spp., it has still brought us some unexpected benefits.

For example, the oxygen in our living areas has become more abundant. Although it is still not as high as the previous oxygen concentration, the feeling of stuffiness has been greatly alleviated.

Secondly, we regained a lot of fertile land, and we planted the roots and seeds of some crops on it, and those crops grew exceptionally well.

Originally, on the land we fenced off, a single potato plant could only yield a pound or two, which was considered a very good result.

However, potatoes planted in this composite soil of *Protoporphyra* benefit from better soil aeration and fertility.

A single potato plant can yield at least four or five pounds, and some exceptionally healthy plants can even produce six or seven pounds.

The potatoes were all about the size of our fist, some even larger, making it a very productive crop.

I've considered that the number of people will continue to grow in the future, so I need to plan ahead for some issues.

We have a lot of land, but we can't use it all for housing.

Having learned from past lessons, we now need to consider issues more long-term and address the most pressing problems first.

The most important thing for a large population growth is food. Housing can be made do for now, but if there is not enough food, there will definitely be big trouble.

We haven't stopped growing crops, but the food we produce is barely enough to feed everyone.

Therefore, the most urgent task now is not to build shelters, but to frantically plant potatoes and cassava, which can be used to fill our stomachs.

Even if we have too many people and nowhere to live later on, it's better to live in the crop base than to starve to death.

The importance of planting cannot be delayed for a moment. The mounds of diatomaceous earth that were not yet fully fermented have been completely filled with potatoes and other crops.

Haru thinks farming is too easy, but their inherent desire to conquer makes them prefer to expand their territory and cultivate more land for everyone to use.

The work of farming naturally fell to our tribesmen. Haru even told us that we didn't have to do anything, just fill the land with crops to provide food.

With ample food supplies, the Haru worked even harder. In order to cut down more Protoporphyra algae to build up the soil, they would even cut down trees for dozens of kilometers.

These ruthless guys worked so hard that the cement production couldn't keep up with their pace of expansion into new territories.

In just five months, thanks to Haru's relentless land reclamation efforts, the area covered by concrete pavement has reached an astonishing 6,000 hectares.

Now, except for those high mountains that aren't covered in concrete, I almost have the illusion of seeing the foundations of a city.
