On the surface, near Nurakita Island, Wei Minsheng's ships and people are throwing earth and rocks every day, and all the work seems to be proceeding in an orderly manner.

And when those villagers were busy carrying earth and rocks to fill in the place where they lived without noticing, the place where Long Hao lived had been used by him to use the power of space, taking advantage of the cover of night and the sound of the waves, to fill in a circular island with a diameter of about seventy meters and a height of five meters.

In order to facilitate future work, a tower crane was also installed in the middle of the island, and a high-power gasoline generator set was used to power it to cover up the anomaly in their ultra-fast island filling action.

With this 70-metre-radius platform, it is possible to plan for the future direction of development.

The construction of Jiangling New City has given Wei Minsheng a lot of inspiration, and if you want to raise the ground, you don't necessarily have to fill it with earth and stones.

It is completely possible to repair the buildings that need to be built underground, and then fill the soil and stone of the building voids in layers.

This can not only save soil and rock, reduce the amount of fill, but also avoid digging when building underground facilities.

As a breakthrough for Wei Minsheng to break into the real world, Tuvalu carries all his future development routes.

So, staying as far away from the threat of waves as possible is his priority.

And you also need to consider how you can maximize the benefits of the place.

As a small island in the sea far from land, the amount of fresh water stored has a direct impact on the quality of life of its residents, because it is the basis of human survival.

Residents of Tuvalu are able to survive during the rainy season from November to March.

But the eight-month dry season required the importation of large quantities of fresh water from neighbouring countries and the delivery of cargo ships to the islands.

While the governments of New Zealand and Australia have provided Tuvalu with two small freshwater purification units to help the drought-stricken country solve its freshwater crisis.

But their freshwater purification capacity can only meet the daily needs of about 3,000 residents, and the freshwater crisis that hangs over Tuvaluans remains unresolved.

Therefore, after discussing with Wei Minsheng, Long Hao and Wei Minsheng planned to build a large reservoir with a diameter of 50 meters on this small island that had just been filled with earth and rocks and had a diameter of 70 meters.

The altitude of five meters has made it impossible to immerse yourself in seawater.

If this 50-meter-diameter pool is built to a 10-meter storage height, it can store nearly 20,000 tons of fresh water.

The reservoir was not built with reinforced concrete, because Wei Minsheng felt that the concrete had too long a maintenance period and was easily eroded by seawater.

On top of that, the newly built cement pond needs to be soaked and changed several times before the water in the pool can be used as drinking water.

After these times were magnified by the time difference between the two worlds eighteen times, it was simply unbearable for Wei Minsheng.

By the time your pool is put into use, a year over there will be almost wasted.

Therefore, Wei Minsheng decided to use granite stones tailored to the other world to build this reservoir.

At the very least, hard granite is not as susceptible to seawater erosion as concrete, and natural stone does not last as long as concrete.

In order to improve the stability of the pool, Wei Minsheng asked Long Hao to use the shared space to control the huge stones to consolidate the foundation of the pool at night when no one was paying attention.

The enormous impact of a multi-ton boulder free-falling from a height of several meters in the air is simply incomparable to that of an ordinary roller.

The effect is also immediate, a pit is smashed, and smaller stones will be smashed into my powder, and there will be no unstable situation at all, and such work efficiency is not the same.

After the foundation was tamped, a widened circular base was built out of large blocks of granite.

The top of the base is roughly leveled by hand, and then the annular wall of the pool is installed on the base.

The basic unit of the annular wall is one meter long, 50 centimeters wide and high, with slight differences in length between the inside and outside, and from above it looks a bit like a trapezoid with almost the same length as the top and bottom.

The dimensions of these stone units are calculated, and all of them are cut in accordance with the assembly line cutting method of standard parts, and the cutting process has been accurate to the millimeter level.

In order to be able to install it accurately, a pedestal was made in the other world that was almost exactly the same as in the real world.

All stone units should be tightly seamed on the base, and the next circle should be made after one circle is completed.

In the first circle of walls, two holes with a diameter of 15 centimeters are drilled in the middle of each stone, and after the whole circle is spliced, the holes are drilled according to the corresponding position of each stone.

It is then fixed with cylindrical granite with a diameter of 14 centimeters in the Ulcon method, in which the gaps are filled with stone powder and solidified with water.

In this way, the first circle of stone units is fixed with the base, and more than 300 stone columns form a resultant force under the cushioning action of the stone powder filler, which is enough to cope with the natural impact force on the horizontal plane.

The cross-section of these stone units resembles a "convex" character, but there is an additional groove below that is consistent with the protrusion above.

The upper and lower stone units are connected by this protrusion and groove, so that the structure can ensure that the up, down, left, and right directions of any stone unit are locked by the adjacent stone units.

Without destroying the stone unit, it can only be disassembled in reverse from the top in the order in which it was installed.

This structure, which does not require cement to be poured, is as simple and convenient as building blocks.

After the completion of the main project of the pool, Long Hao filled the soil and stone around the pool and compacted it layer by layer, using mud to realize the sealing of the gap in the pool.

The surrounding landfill also forms an inward prestress to counteract the outward pressure of the water inside the impounded tank on the pool wall.

Such pools are ready for use as soon as they are completed, and do not require fresh water maintenance like concrete structures, and the maintenance process must be protected from the effects of high temperatures.

In this place where mineral water is more expensive than oil, 20,000 tons of fresh water without any pollution, even if it is not comparable to the price of mineral water, is enough to create a net income of more than 5 million Australian dollars for Wei Minsheng.

Of course, these revenues exist in the form of Australian dollars, which Wei Minsheng can use to directly buy a large amount of fuel, and for Wei Minsheng and Long Hao, who have shared space, this can be done with just a wave of their hands.

Long Hao also temporarily installed some brief living facilities on this small island, while meeting his own needs, he can also provide some necessary living materials to the islanders, of course, these vegetables, fresh water and other necessary living materials still need to be exchanged for money, but the price is about two percent lower than the price they buy on other islands.
