At the same time that Emperor Shi Tian asked you to release the water, a huge portal had just opened at one end of the Grand Canal, and then a huge stream of water erupted from it, and it rushed down in a blink of an eye.

Thankfully, the bottom of the river was magically fortified and steely, otherwise the torrent alone would have washed away the dirt at the bottom of the river.

Soon, this big river will gradually grow water, so that it will not be able to fill it in a short time, but I believe that in a month or two, it should be turned into a real canal.

And the most important thing is that there are many fish in the water of the swamp, and in the deep water area where Emperor Shi Tian opened the portal, it is a paradise for fish, and now that there is suddenly such a big funnel, naturally a large number of fish are rushed in.

Therefore, in the future, this canal will definitely become a huge fish pond, which will produce a large amount of meat, thus providing the tribe of Emperor Shakti with aquatic products that did not exist before.

In fact, Emperor Shi Tian had already expected this, and in order to make the fish have something to eat, Emperor Shi Tian had even asked the Holy Maiden of Yuelan to prepare some aquatic plants, which were thrown into the river after being born as food and spawning grounds for fish.

Not only that, but special plants will begin to grow on both sides of the river, and the fallen leaves, flowers and fruits of the plants will fall into the river water and become food for fish, which is also a special food chain.

Of course, the specific work does not need to be done by Emperor Shi Tian, as long as he puts forward ideas, he can't divide them, and the Holy Maiden of Yuelan will naturally organize people to do it.

And just as the Grand Canal officially began to fill with water, Yaslian and Aladdin finally teamed up to invent the first magic engine.

In fact, this thing has been around for a long time, and it is nothing more than using lightning circles to create electricity, and then using electricity to urge the magnet to rotate, so this thing is both a generator and an engine.

The core power component of the flywheel robot under Princess Lionheart is also based on this principle.

Yaslian and Aladdin are both demigod-level alchemy masters, although their strength is limited, but their knowledge and wisdom have not had the slightest impact, and the magic engine they invented is much stronger than Princess Lionheart's transformation engine.

It's just a square iron lump weighing two or three hundred kilograms, which can achieve a maximum output of 400 horsepower, which is really terrifying.

Moreover, this is the reason why they don't use magic metal, and if they do, they can double or even triple their performance.

Hearing this, Emperor Shi Tian's eyes suddenly lit up, if the commission is really so high, not to mention tractors and cars, even tanks and ships can be built, right?

So Emperor Shi Tian didn't have any nonsense, and immediately asked them to use magic metal to create a more powerful magic engine.

At the same time, the barrage Ji also invented the tractor.

Since there are no roads at all, and the ground is soft, it is easy to get stuck in the wheels, and there is not much rubber, so Danmaku Ji invented a tracked tractor.

For a scientist in the interstellar age, an ordinary tracked tractor is as simple as a child's toy, and it doesn't take much effort at all.

After installing the engine and the unique magic tank, the tractor was successfully started.

However, the speed of this tractor is quite slow, only 35 kilometers per hour and a top speed of 35 kilometers per hour.

And every 100 kilometers will consume one kilogram of mana water, which is a little larger.

In addition, the quality of the steel is not particularly passable, so it is more worn, and it is necessary to maintain it after driving thousands of kilometers.

If rubber tires are used, not only can the speed be increased a lot, but the wear rate will also be reduced.

But alas, at least for now, don't even think about it.

Emperor Shi Tian has just solved the problem of food and clothing here, and all the energy of the Holy Maiden of Yuelan has to be used to plant magic moss and magic plants, and it is impossible to plant rubber trees on a large scale.

And it's useless to have rubber trees, you have to process it into finished rubber, and then process the finished rubber into tires, which is too big a step.

Not to mention the construction of a large forest, two processing plants, and a large number of technicians, it is certainly not possible to do it in a short time.

In desperation, Emperor Shi Tian could only put the rubber matter aside for the time being.

Although this kind of tractor is extremely garbage for Emperor Shi Tian.

However, Emperor Shi Tian still did not hesitate and ordered mass production.

The first was the construction of several parts factories, and then the assembly workshop, which required more than 100,000 workers, to say the least.

The reason why the tractor is so crazy is actually a helpless move of Emperor Shitian.

You must know that since they had the Wood Spirit Bead, the Yuelan Holy Maidens and their sisters could dye thousands of square kilometers of land green every day.

And such a terrifying expansion speed is still increasing, because dozens of flower fairies are produced every day.

In this case, the cavemen who take care of the magic moss are a bit insufficient.

Because of the Jiangshan Sheji space, it is an extremely arid and water-scarce place.

If you just plant Magic Moss and leave it alone, Magic Moss will soon die alive.

So in order to prevent this, Emperor Shakti had to send a large number of cave people to water.

Of course, it is not necessary in the core area, because there is plenty of water in the core area, and the air already contains enough water, so there is no need for watering.

However, in the marginal areas, the moisture content is still insufficient, and it is still escaping to the periphery, so if you don't water it, you will die of thirst.

But cavemen are creatures with little strength and little stamina.

Although they push the waterwheel and water very hard every day, the area they actually take care of is not particularly large.

The reason is that the mode of transportation is too backward, and after the four-wheeled waterwheel is loaded with water, the four cave people can barely push it by pushing hard, and the speed is very slow.

And there wasn't much water on the watermill at all, so it would soon run out, and then it would have to go back and continue transporting.

At the beginning, the area of the magic moss was small, and the number of cave people had indeed exceeded one million a long time ago, so naturally there was no big problem.

However, with the outbreak of the Yuelan Maiden, the area of the magic moss skyrocketed, and the watering speed of the cave people obviously couldn't keep up.

Of course, powerful orcs and minotaurs can be used instead of cave people to water, but for them, this kind of work does not play much of a work, and it is difficult to stimulate fighting spirit.

The most important thing is, they are here, what about the mines? It will inevitably delay the production of iron ore.

It is precisely because of this that Emperor Shi Tian thought of tractors.

And facts have proved that Emperor Shi Tian is indeed a wise monarch, and he sees the problem profoundly.

The tractor, a simple machine that can no longer be a turtle, is really an artifact for liberating the productive forces.

When a large number of tractors were equipped to the cavemen's village, their work efficiency increased dozens of times in an instant.

A single cave man driving a tractor can distribute a bucket truck loaded with a large amount of water, weighing at least ten times as much as a four-wheeler, but traveling much faster than pushing a four-wheeler.

The most important thing is that the cave people no longer need to stop watering, they just need to stand on the bucket truck and keep splashing water, which saves too much effort than before, and the efficiency is dozens of times higher.

The problem of insufficient watering capacity was solved at once.

And this is just the beginning, as the number of tractors has skyrocketed, the production capacity of Emperor Shitian's entire territory has increased tenfold and tenfold.

After the special tractor for watering, there is the tractor for agricultural planting.

The first is the harvester, a caveman driving a tractor with a harvester, constantly moving back and forth in the vast savannah.

The harvester harvests the mature grass seeds, which are then easily gathered to obtain a large amount of grass seeds.

Next, the grass seeds are transported by tractor to the core of the space.

Then there would be caves, and people would start throwing grass seeds to let them take root and sprout on the magic moss.

If there is no human intervention, the grassland in the space will gradually expand, but the speed is definitely slow.

But with the help of tractors, it's a different story, with hundreds of square kilometers of land planted with grass seeds almost every day, and it doesn't take a few months for the grass to grow glowing grass.

Since they are in the core of the territory, there is already enough moisture in the air here, and there is a water source nearby that is constantly evaporating, so they can grow easily.

After having a large amount of grassland, Emperor Shi Tian can start raising all kinds of livestock, in addition to cattle and sheep that can only be used as meat, there are also bighorn demon sheep that can be used to produce necromantic chariots, which are also specially cultivated.

Although Emperor Shi Tian has barely solved the problem of meat, in fact, it is not a long-term solution, because the Alchemy Ranch wants to produce meat at a high speed, and it has to consume tens of thousands of black iron law coins every day, even if Emperor Shi Tian is rich, he can't stand it for a long time.

Therefore, the alchemy ranch can only be an emergency measure, and if you want to have enough meat, you must also expand the scale of the pasture.

And without the help of tractors, expanding the scale of the grassland can only be an empty word, and counting on the automatic expansion of the playground may have to wait for dozens or hundreds of years.

If you want to count on the little strength of the cave people to expand, hehe, it's basically unrealistic, how many grass seeds can those little short legs collect in a day? How many grass seeds can they throw?

I'm afraid that the transportation problem of thousands of kilometers is not something that can be solved by the small body of the cave people and their own two legs.

Therefore, it can almost be said that this pasture is completely pushed by a large number of tractors.

In addition, the mine is also where tractors come in, and although Crazy Iron Dogs can also transport them, and they are tireless, but their transport volume is just too pitiful.

On a small scale, Crazy Iron Dog can still use it, but with the explosion of ore production, Crazy Iron Dog alone can't do it, and it has to be a tractor that can pull more than a dozen tons of ore at a time.
