Solving this social problem is urgent; I need to get everyone busy as soon as possible. Otherwise, if everyone huddles together and wastes time, a major problem will inevitably arise sooner or later.

The next day, I assigned the new tasks.

Haru, who hadn't had any work for a long time, were practically glowing with excitement at the prospect of continuing their infrastructure work.

I don't know why these Haru people have such a fascination with infrastructure work. Is it simply because infrastructure work requires more effort than other jobs, allowing them to release their pent-up energy?

Many Haru have inquired about the specific project, whether the construction period would be too short, and whether it would be completed in a short time.

Judging from Haru's tone, it seems like they should be the ones building Qin Shi Huang's Great Wall. And yet, someone's worried there won't be enough work for them. Haru truly deserves the title of "devil."

I felt a little ashamed after hearing that; these Haru really can't stay idle for a moment.

I composed myself and assured Haru that as long as they were willing to work, they could work for hundreds of years and still not finish.

Just kidding, if you wanted to level all the land invaded by Protozoa and cover it with a layer of concrete, it would probably take longer than rebuilding the Great Wall several times over.

Haru's army, however, did not see it that way; on the contrary, they were very happy. These days had been so stifling for them; their bodies, born of war, were inherently restless.

They felt that this peaceful life was too boring, and not as fulfilling as the sweat and toil they used to put into infrastructure construction.

I can only lament that Haru didn't come to the right world. If they had come to our world, those unscrupulous merchants and unscrupulous factory owners would have been overjoyed, setting off firecrackers to welcome their arrival.

On the first day, all the Haru rushed to do the work. Pay was irrelevant; they just wanted a fulfilling and comfortable experience.

This put our tribesmen in an awkward position, as all the work was taken by the Haru, and some Haru almost got into fights because they arrived late and didn't get any work.

We, a bunch of grown men, could only work alongside the women, doing things like cooking, washing vegetables, farming, and feeding pigs.

Some men in the tribe, having nothing else to do, actually became nannies, taking care of the hundreds of children.

Everyone started to unleash their enthusiasm again. Haru was probably going crazy from being cooped up lately, and they were working even more ruthlessly than before!

Originally, quarrying stones involved first blasting them with explosives, and then breaking the large stones into smaller pieces using a stone hammer.

But the Haru were too enthusiastic; there was no need to recruit them, they came on their own initiative. The key was that there were so many Haru that the rocks blasted down by a single blast were completely smashed by the Haru in no time.

Many Haru were dissatisfied with this, feeling that the work was not exciting at all, and they took the initiative to pick up stone hammers and directly confront the rocks of the mountain.

Unfortunately, I had to operate several mines simultaneously, and once these Haru people learned how to blast rocks, they didn't follow my safety standards at all.

These damn Haru people weren't just setting off one or two stone cannons to split the mountain; they were firing strings and strings of them. The entire mountaintop sounded like it was being set off with firecrackers, the booming sounds never ceasing.

The reason they did this left me speechless. Haru's idea was simple: they wanted to flatten a mountain as quickly as possible, so they would feel a great sense of accomplishment in conquering the entire mountain.

These monsters are indeed beyond the comprehension of common sense. Now, the Haru army is attacking those stones like madmen.

For the first two days, they were so excited that they didn't want to sleep, and they were determined to flatten that mountain even with flashlights in hand.

With these enthusiastic workers, our cement production process went smoothly. The first batch of experimental cement was produced in three days, and it was also my first time producing cement, a building material.

I learned these methods and steps for making cement from my father. He worked in a cement factory for a while in his early years, but the business didn't go well, so he switched to being a bricklayer.

Looking at the cement that had been made, I still felt a little uneasy. This was crucial to whether we could reclaim the land in the future, and it was also the only way to solve problems such as overpopulation.

I asked my clansmen to bring over the selected concrete aggregates and mix the dry cement and aggregates evenly according to a ratio of one part cement to four parts aggregates.

A large pit was dug in the middle of the mixture, and the Haru began to pour water into the pit using leather buckets made of tree bark, as I instructed.

When the water in the pit reached two-thirds full, I told everyone to stop adding water.

We started shoveling the mixed dry material from the edge into the puddle, and soon the black concrete began to turn into a sticky slurry.

The first place for the experiment was the area outside the ditch that we had been cleaning with sticks. We put the mixed concrete in buckets and poured it onto the open ground outside the ditch.

Since no one had done this job before, I had to do it myself. I was too lazy to make a metal plastering trowel, so I made one directly from a piece of wood I had sawed out.

Although I'm not as professional as my father and his colleagues, I can still easily level the ground.

A large amount of concrete is used to pave the ground, but it can't cover very far; a considerable quantity of this stuff is required.

In less than half an hour, all the concrete had been transported by the Haru people to the open space outside the canal.

I didn't know how thick the concrete needed to be, so I poured it according to the standard thickness of ten centimeters for highways.

After roughly leveling the ground, the next step is to wait for the concrete to dry on its own.

Based on the drying speed of concrete, it will harden within one or two hours. In just one night, the concrete can initially bear weight, and there is no problem at all for several people to stand on it.

Two hours later, I went to check the poured concrete again and found that it had hardened and I could no longer poke it with my finger.

Haru and our people were also very curious. This thing was just a lump of mud a moment ago, but it has hardened in such a short time.

At first glance, my concrete work seems to be successful, but it's not safe to walk on it yet.

We'll have to wait until tomorrow to reach a conclusion on the success of this cement. I've already explained the precautions to everyone.

Everyone is also very curious to see what this thing I'm talking about, which can become as hard as stone, will look like tomorrow.

As I requested, quite a few people still came to watch. However, everyone resisted the urge to step on it, at most poking it with their fingers.

Time flew by, and the night passed. The next morning, the area was already packed with tribesmen and Haru people who had come to watch the spectacle.
