The key is that everyone can have enough to eat, and there's no need for constant mental stress and paranoia. There's no death or bloodshed, and the expansion speed is quite stable.
Haru knew that if they wanted to continue to grow and maintain this large group, cooperating with us was the brightest path forward.
After spending this time together, Haru discovered how big the world really is.
When they went to dig the irrigation canals, it took them a year to complete just a small section of that land, working day and night.
Now they realize how ridiculous it was to have listened to the slander of those gods, and that they could never control every part of the world.
Take the land on the other side of the river, for example. If they and humans hadn't built large ships to cross the river, Haru probably wouldn't have known what the other side looked like, let alone controlled it, even if he spent his entire life doing so.
Although our world is facing a major crisis, life is gradually getting better through our efforts.
The twenty-odd wild boars we brought earlier were also very productive; they produced over a hundred piglets in the first year alone.
We fenced off a cleared hilltop and let the wild boars roam freely on the mountain.
Actually, we could have just let those wild boars roam freely in this area, but we've also planted quite a few crops.
To prevent wild boars from damaging the crops and to facilitate centralized management, we decided to enclose and raise them in enclosures.
Later, there were so many wild boars that we couldn't accommodate them all on our side, so we had to move them to a few open spaces on the other side of the river, where Haru, who was stationed there year-round, would raise them.
Haru discovered that this novel farming method was much easier than hunting for meat. Therefore, he treated the piglets with even more care than his own sons.
Every day, Haru makes new discoveries and offers diverse new options, a stark contrast to their previous singular war mode.
No one is born a war-loving madman, and these Haru are no exception. After experiencing the sweetness of life other than war, they feel that their current life is the life they truly yearn for.
Three years later, the land on the other side of the river still hadn't escaped the danger of being invaded by Prosopa spp. Fortunately, we had already cleared out a large area of land, which could be used for logging in rotation.
After clearing a piece of land, immediately replant it with saplings.
Because the saplings we selected are all fast-growing, tall and straight tree species, they will grow into large trees in just a few years and be harvested again.
To reduce the weight of the transport, we also built a large sawmill in a centrally located area on the opposite bank of the river.
This way, the logs from the other side of the river don't need to be transported to the shipyard for processing. The felled logs can be transported directly to the sawmill by waterway.
The large saw blade inside, which is over three meters tall, took us a week to develop through repeated experiments before finally being forged from a long iron block that had been cast in a mold.
The serrations are also cold-rolled out using chisels and hammers when the sheet metal is heated to a bright red, and then the serrations are quenched a second time to harden them.
The entire sawmill is driven by water power through a gearbox, and we have specially built a V-shaped water flow channel upstream.
The water flow became extremely rapid after passing through the waterwheel, which provided a stable power source for the large wood saw.
We have made great progress in ensuring a steady supply of timber raw materials.
However, there are still many problems. Due to the large size of the ship, there is enormous pressure in many places.
So we came up with the idea of using naturally growing rock vines with artificial guidance, and using the outer wall of the ship as a climbing cliff for the rock vines.
The rock vines hung down from the ship's deck all the way to the ground. Instead of letting these hanging vines take root, we arranged them tightly around the bottom of the ship and used ropes to pull them up to continue growing onto the other side of the deck.
These rock vines are somewhat similar to Virginia creeper, with their climbing roots firmly attached to the wood at the bottom of the boat.
The rock vines grow very quickly. With human intervention, they quickly spread from one side of the deck to the other and took root on the other side of the deck.
These rock vines act like natural, intelligent repair tools, constantly growing thick vines on the hull's outer wall to firmly hold it in place.
From a distance, the ship's hull was covered by rings of rock vines, making it impossible to tell that it was a ship. It looked more like some kind of mutated giant bio-engineered entity.
The rock vines provided excellent protection for the ship's hull. Even in the event of a collision, the rock vines acted like armor, leaving the wooden interior undamaged.
Moreover, these damaged armor plates can repair themselves, which greatly saves on huge amounts of manual maintenance work.
The Ark usually docks near a U-shaped backwater surrounded by two large mountains, covering an area of over a thousand square meters.
This location is still several dozen meters from the shore. Because two large mountains block the flow of the river, the water here flows much slower than in other places, which naturally makes it the place where the ark can dock.
Since it's not far from the shore, we anchored here as a backup survival base.
However, this period of prosperity was short-lived. After twenty years of development, some problems gradually emerged. The numerical advantage that initially helped us complete the Ark experienced explosive growth after twenty years of peace.
We once thought we had acquired enough land, but the ever-growing population has quickly filled up all that land.
The most obvious example of the population problem is the Haru race, which was specifically used for warfare. They only took a little over ten years to restore their population to a level where they could rival the two major tribes.
After twenty years of living without any war damage, the number of Haru has grown to an extremely exaggerated level.
According to preliminary statistics, the number of people from Haru already accounts for more than 80% of our total population. In terms of sheer numbers, they far exceed ours by countless times.
It was this rapidly expanding population that saved everyone, allowing for the creation of more land and even the construction of the Ark.
But now, this rapidly expanding population is putting immense pressure on everyone. There's only so much land; where will the extra people live?
Numerous sensitive issues and some friction began to emerge. Haru believed that their tribe had put in countless times more effort than ordinary people, and that their people should be provided with shelter.
But our tribespeople weren't happy about it either. If we hadn't taken these Haru in, they would have starved to death many years ago.
Besides, without technical support from his own side, what can Haru do with all his strength?
