The correct way to open the sprite

.

The Pinus tabulaeformis along the river in the Xueding Mountains has almost been cut down. Now along the Lengshui River, the originally lush coniferous forest in the Xueding Mountains on the west bank has turned into barren tree stumps.

However, it was these woods that accelerated the development of Cattail City. As the amount of wood needed in the construction field of Cattail City became smaller and smaller, these woods had a new application, that is, as sleepers for railroad tracks.

As a large number of sand people joined and the population of Cattail City grew again, more workers were put into the desert railway line.

After the two ends were constructed together, they were finally connected smoothly and the overall construction was completed, becoming the second railway line in the Greon World, the Cattail City to Golden City railway line.

Thanks to the flat terrain of the great wilderness and desert coastal areas, the railway construction in Cattail City could be completed so quickly.

After passing the test, the oil train carrying the oil tank set off from Cattail City and rushed all the way to Golden City.

The oil train was followed closely by the supplies train, which also carried flatbed carriages carrying the Antlers armored fighting vehicles and engineering machinery assigned to the Golden City to support the defense and construction of the Golden City.

Due to the threat of plane war and the threat of sea fishmen, the train leading to the Golden City has armored carriages at the beginning and end to defend against possible dangers.

"Oil supply will finally enter the era of large quantities and full control." Feng Yu muttered quietly as he looked at the departing special train.

Ilia said to Feng Yu from the side: "Teacher, I think our locomotives and power plants should not all be replaced with fuel equipment. The Golden City is too far away from us. If something happens there, it may Bringing our Cattail City to a standstill.”

"Of course the power plant does not have to install fuel-fired power generation equipment. The flint ore reserves in the wilderness are so large, and our workers are familiar with thermal power, so there is no need to build a new fuel-fired power plant.

Even if it is built in the future, it will be built in Golden City, and a transmission line will be built to directly transmit the power back to Cattail City.

But that shouldn't be necessary. After all, Cattail City's current power generation capacity can still meet demand.

The important thing is trains and battleships. These things are too slow to start with steam power. They are fine in normal times, but there is no time to react to any emergencies during war.

And we are not dismantling the steam-powered locomotives and steam battleships now, but sealing them together with the weapons so that they can be used for emergencies when needed. "

Illya nodded: "The new refinery has passed the test. As soon as the oil train comes back, the machine can be started to refine oil.

Teacher, the civilian vehicle project is temporarily closed?"

"Well, let's first produce more Antlers armored fighting vehicles and earth-moving trucks to double our planned mobile force, and then produce more for backup replacement.

We must first develop the super project of hydropower. Many of the scientific research projects in the future will be power-hungry and cannot be carried out without super hydropower stations.

As for the dwarf kingdom, choose a place to build a thermal power plant around their flint mine. They don't use much electricity anyway, so a smaller one is fine.

And letting them build and use it themselves can also save us some workers. "

Illya asked: "Are there not enough trucks now?"

Feng Yu thought for a while and said: "If it's a little less, it's almost enough to replace people without changing cars. But now the performance of these vehicles is unstable, and I'm afraid they won't be able to withstand continuous use for a long time, so it's better to produce more for rotation and use." It’s better maintained.”

"What about the Hazy Moon Forest?"

"Have we recruited enough elf warriors?"

"That's almost it. King Minai sent us warriors, and I divided them up and assigned them to various teams."

"Then let them do the rest. Anyway, there are wilderness railway lines and shipping, and we have the ability to quickly transfer the elves there. When that time comes, we can make better arrangements."

Two months later, in the morning, a huge convoy of trucks drove out of Cattail City and entered the wilderness along the road heading east from Cattail City.

Feng Yu drove the car, leading the way with Nicole. He was followed by several newly produced and improved jeeps, and he led the entire convoy to park in the wilderness east of the industrial zone.

At this time, many wooden poles have been nailed as markers on the vast wilderness here, and many large machinery have also arrived.

"We're here, come on down. The soil for the Lengshui River interception project is here." Feng Yu helped Nicole get out of the car and waved the others to get off.

Borui looked at the wooden poles nailed in the wilderness and said, "Is there a scope for digging?"

Feng Yu waved his hand and let the truck drive into the earth-extraction operation area. He turned around and said, "Of course there is a scope."

He led everyone to a newly built fortress here, pointed to the wooden pole mark on the wasteland and said: "Look, the range of the wooden pole is the range where we collect soil.

This range starts from the fort in the east and extends to the north-west direction.

After the earth-boring project is completed, a deep arc-shaped pit about [-] meters wide will be dug out to the fortress near the wasteland railway line, with an average depth of about ten meters.

We all know that the water wells we dig in the wilderness are about 15 meters from the water surface to the wellhead. Taking soil and digging ten meters will not dig out water compared to the 15 meters deep underground water level. It will not affect our earth borrowing project.

When the Lengshui River interception project is completed and the water level of the Lengshui River rises, it will inevitably cause the overall groundwater level in the Great Wasteland to rise.

The arc-shaped trench we dug out will turn into a pond with steep sides and a moat in the southeast direction of Cattail City. This is why we have to go all the way here to get soil.

As for the excavation of soil on the edge of the great wasteland next to the alluvial plain, that is a small project. It is just to repair the large soil slope. The excess soil is shoveled away and then reinforced with walls made of bricks and stone powder to build a natural city wall. . "

"It's so far to dig, how long will it take to dig?"

"Quickly, the key is the earth-extraction project, which has been fully mechanized. You will be able to see it later."

In the eyes of these Gerien natives, fetching soil is nothing more than digging with pickaxes and other tools, and then transporting it away in baskets. Even if they know about vehicles, they still do not break away from the concept of using pickaxes and other tools to dig soil.

The driver of the loader was not yet skilled, but even so, he was able to finish loading a truck several times.

The loaded truck slowly drove out of the earth-borrowing operation area, passed by the fortress where Feng Yu and others were standing, and drove back toward Cattail City.

This is not the reason why everyone is surprised. What is surprising is that there are dozens of these machines that can easily fill the ground with a large shovel of soil and then dump it onto the truck.
