In that case, the length of the ship would need to be increased to around 600 or 700 meters. The width, however, could be reduced somewhat, to around 180 meters.

The shipbuilding project proceeded amidst numerous setbacks. The ark, originally intended to be completed within a few years, actually involved a much larger amount of engineering work and encountered far more challenges than we had anticipated.

This ark is perhaps the longest thing I have ever built; it took us all a full twenty years to complete it.

During this period, the light scheme was adjusted and revised dozens of times, and finally the length of the ark was set at 500 meters, the width at 200 meters, and the height at 70 meters.

Because the deepest part of the soil filling the surface reached an astonishing three meters, the weight of the entire ark was also terrifying.

Those aircraft carriers that casually claim to displace tens of thousands of tons would probably look rather small in front of this behemoth.

It is larger than any aircraft carrier in the world, with a draft of an astonishing 18 meters and a displacement estimated at over 200,000 tons.

However, this enormous ark lacked a propulsion system, not because they didn't want to install one, but because all their knowledge had been completely drained, and their brain cells were almost completely exhausted.

We can call this ark, or perhaps it would be more accurate to call it a giant aquatic survival platform.

To successfully build such an ark, we practically pulled out all our hair; the biggest problem was the shortage of wood.

In the first two years, we used up all the timber from the three mountains, only to find out later that it wasn't enough for the Ark.

In the end, we had to change our minds and build a large ship. We sailed the ship to the other side of the river, which had not yet been infected by the Protozoa, to frantically cut down trees and then transport them back to our side to process and build the ark.

During this period, we encountered many problems in logging and transportation, such as navigation. To address this, we built two giant lighthouses, each 20 meters high, on the mountains in both locations to guide the ships.

Even so, many problems still arise during the rainy season. The rising water level and surging river force the waterwheels to operate beyond their capacity, and they have been smashed to pieces by the flood several times.

Even the cypress algae closer to the river were directly uprooted and washed away by the current. Fortunately, the closest part of our canal to the river is still more than ten meters away.

In addition, the river was extremely wide, so even when the water rose, it did not reach the vicinity of our camp.

The sight of those Prosopa spp. washed away by the flood was quite alarming. If these things, carrying some residual mycelium, made it to the other side of the river, we probably won't need to cut down any more trees.

With this in mind, apart from the necessary personnel who stayed behind to manage the daily affairs of the settlement, we immediately mobilized all our tribesmen and Haru to head to the other side.

Before that area was invaded by Prosopa spp., we spent a full year demarcating an ultra-long irrigation canal with a total circumference of more than 26,000 kilometers!

The hardships involved are no less than those of building the Great Wall, because we are constantly worried that the land beneath our feet will be infected by Protozoa. Our daily workload is generally eighteen to nineteen hours of high-intensity work.

During this period, the land was not fenced off all at once. Instead, we used the same method we had used before to fence off land here, framing a piece of land stretching for ten or twenty kilometers along the riverbank every two or three days.

Then it continued to spread out in circles, encircling the land along the river with water canals and connecting them into one piece. There were no fewer than two hundred waterwheels built here, and the scale of the project was astonishing.

Fortunately, we discovered many rich mineral resources during our land acquisition process, including salt mines, iron mines, sulfur mines, and other high-value minerals.

These minerals also directly support the source of materials needed in many of our industries, the most important of which is the acquisition of raw materials for explosives used in quarrying.

In some important sulfur mining areas, we even established a dedicated facility on that land for the large-scale production of chemical raw materials.

A large part of the credit for this was actually given to our former mortal enemies. It turns out that if these Haru people stopped fighting, they could have focused their energy on infrastructure development and achieved equally impressive results.

During certain critical periods, these Haru warriors were even willing to work for twenty hours a day while on drugs. Apart from the four hours of rest and sleep, they would even eat during the intense work process.

It has to be said that this kind of relentless, all-out fighting spirit is something that even we can't help but admire and feel ashamed of ourselves for.

Moreover, Haru, this modified war machine, is far superior to us in terms of personnel recovery speed.

Like us, they can be in estrus all year round, so as long as there is enough food, a stable environment, and all their energy is put to good use.

Haru breeds throughout the year, and their gestation period is short, only three months. Each litter has at least two offspring, usually between three and four, and can have up to five or more.

Since a pair of Haru don't have to worry too much about food, they can produce up to four offspring a year, with a total number of twenty or even more.

Over the course of a year, our children have only grown a year older. Meanwhile, many of their children have already reached adulthood and are old enough to reproduce.

Based on the number of over two hundred female Haru on Haru's side, their population grew by more than two thousand newborn Haru in just the first year.

This was because food was somewhat scarce at the time, and some of the Haru were getting old, so they dared not expand production.

If they were allowed to reproduce freely, it wouldn't be a dream to produce around three thousand newborn Haru.

With such terrifying reproductive capacity, it's estimated that only the second brother of pigs can rival them.

The title of "war machine" is truly well-deserved; in every aspect, Haru deserves the title of "devil."

It is precisely because of these Haru armies that vital human resources were supplied to various key locations to maintain the operation of these areas, enabling our plan to be realized within twenty years.

Otherwise, with the limited human resources we have, it would take forever to build the Ark.

Gradually, people's views on Haru changed. As long as there was a place for these energetic Haru to unleash their enthusiasm, they were a group of infrastructure maniacs who treated construction projects as enemies.

Moreover, once these Haru people undergo a fundamental change in their hearts, their suspicions will be completely dispelled, and they will treat our people the same way they treat their own.

They are well aware that their rapid population recovery is largely due to the efforts of their former enemies.

This showed them a completely new path of cooperation, much faster than the way Haru's gods had pointed out to them to expand their population through war.
