And when the tractor was attacking frantically, Emperor Shi Tian continued to dig rivers and water storage lakes with his subordinates.

There is no way, the territory is so large, and there is no way to meet the problems of irrigation and transportation with just one canal.

Emperor Shakti planned to dig two cross-shaped canals, and then dig some reservoir lakes in the middle, and connect the two canals with a river channel, forming a dense channel in the shape of a spider's web.

In this way, not only is it easier to transport, but also easy to irrigate.

The most important thing is that a large amount of open-air water surface can not only be used to raise fish and flowers, but also expand the evaporation area and further enhance the water vapor content of the entire space.

Of course, in this way, the amount of water consumed will also become more.

Fortunately, Emperor Shi Tian is not short of magic water now, and in order to build his own territory, he is also out of the way.

After five months of frenzied busyness, the spider-web-like water web was almost completed, and even the water was full.

The tractor production plant has also been established for three months, and thousands of tractors have already begun to work.

At this time, the problem of rubber could not be ignored by Emperor Shitian.

Without rubber tires, the efficiency of the tractor is really a little low.

And if you want to produce larger vehicles, you will definitely be inseparable from the help of rubber tires.

In desperation, Emperor Shi had no choice but to ask the Yuelan Holy Maiden to temporarily stop expanding the magic moss and instead plant rubber trees in a large area.

Moreover, this is a rubber tree upgraded by Emperor Shi Tian with a bronze tripod, which has a fast growth rate and strong rubber production capacity.

The only restriction is that the number is small, if you want to meet the needs of Emperor Shitian, you have to get tens of millions of acres, anyway, in a short period of time, the Holy Maiden of Yuelan doesn't want to do anything else.

And just when Emperor Shi Tian was busy and was about to take a break, Princess Lionheart came to the door with a little rabbit and excitedly.

As soon as Emperor Shi Tian saw the other party's appearance, he knew that something good was going on, and couldn't help but smile and said, "Have you found something good?"

When Emperor Shi Tian was crazy and busy with internal affairs, Princess Lionheart and Little Rabbit naturally did not have idle, they kept sweeping the territory on the second floor of the dungeon, killing monsters, looking for resources, and rarely came back, which was also very hard.

In fact, a large part of the funds in Emperor Shi Tian's hands are all from other people, and it may be too much to say that Emperor Shi Tian is a little white face, but at least he can be regarded as eating a few mouthfuls of soft rice.

Anyway, when Emperor Shi Tian saw them, both of them had a simple appearance, which made Emperor Shi Tian feel distressed.

Princess Lionheart smiled slightly and said, "At present, those things are nothing more than getting some law coins, materials and the like, which are not too brilliant." ”

"Then why did you come back in such a hurry?" said Emperor Shi Tian as he asked the second daughter to sit down and personally poured them a glass of rare fruit wine.

Princess Lionheart gracefully took a sip and continued, "I came back this time to ask for help. ”

The little rabbit took a sip unceremoniously, then stretched out the empty wine glass in front of Emperor Shi Tian, and said proudly: "We have a new invention, you have to support us to make it." ”

"Huh?" Emperor Shi Tian casually poured another glass of wine for the little rabbit, and then asked curiously, "What is the new invention?"

"It's a flying attachment for a flywheel robot. Princess Lionheart smiled and said, "I was idle and bored on the march, so I did some research and succeeded by luck." ”

Hearing this, Emperor Shi Tiandi's eyes suddenly lit up, and he couldn't help but say, "If the flywheel robot can fly, then it's not garbage!"

After finishing speaking, Emperor Shi Tian immediately realized that he had lost his words, and his old face immediately turned red, and he hurriedly explained with a wry smile: "That's not what I mean?"

"What do you mean?" said the little rabbit angrily, "You just hate our robots as garbage?"

"This~" Emperor Shi Tian suddenly looked depressed, and secretly said in his heart, "Why did you accidentally tell the truth?"

That's right, the flywheel robot may be a powerful class with diverse uses and excellent performance in the eyes of others, but in the eyes of Emperor Shitian, it is indeed garbage.

The reason is also very simple, that is, the cost is a little high, and it is too precise and easy to break.

According to Emperor Shi Tian's understanding, the flywheel robots made by Princess Lionheart cost more than 100 each, black iron law coins.

And the tractor made by Emperor Shi Tian, the cost price may not even have ten black iron law coins.

When it comes to doing rough work, tractors are indeed not as good as flywheel robots, but they are not too much different.

But the problem is that the tractor is very bulky, not easy to break, and easy to repair if broken, and the accessories are not worth a few dollars.

But the flywheel robot is different, if this thing breaks, the repair cost will be a dozen, or even dozens of black iron law coins, which is the cost of a few tractors.

It is precisely because of this that Emperor Shi Tian did not replace the tractor with a flywheel robot and carried out large-scale promotion, which is really a bit unaffordable.

In fact, this is not a problem with the performance of the flywheel robot itself, nor is it a problem with Princess Lionheart's ability, but the limited conditions and no way to do it.

Princess Lionheart was a guerrilla after all, and she only had very few resources in her hands, and she was able to create a basic maintenance robot like a flywheel robot, which was already very powerful, and it could even be said that it was beyond the imagination of Emperor Shitian.

Strictly speaking, the cost performance of the flywheel robot is definitely very high, especially in transportation, which can be combined into an eight-wheeled, or even a 100-wheel super car, which can be used as a train.

However, don't forget that when the flywheel robot was designed, it was used inside the battleship, and the ground was unusually flat, so the requirements for shock absorption were not high, although there was also a very good shock absorption system, but the shock absorption system was only used occasionally, and it must not be used regularly, and it would be easy to have problems.

But after arriving in the underground world, Princess Lionheart created the flywheel robot again, and found that although this thing is also extremely good in the underground world, and can move quickly regardless of almost any terrain, its service life has been greatly reduced.

Because there is no flat road surface in the underground world, almost all of them are bumpy all the way, can the wear rate not be high?

After all, Princess Lionheart is only a newcomer and has limited resources, so she knows that she has this weakness, so she can only make it in large quantities.

But for a discerning person like Emperor Shitian, the flywheel robot with low service life and high maintenance costs is really a garbage class.

Of course, Emperor Shi Tian would never say this, but in his heart, he still classified it as garbage, and he usually didn't even mention it.

And today, it is obvious that Emperor Shi Tian is quick to speak, so he said his true thoughts.

Princess Lionheart was also a little annoyed at first, but after thinking about it carefully, she found that they were indeed right.

Emperor Shi Tian was originally an interstellar emperor, and the resources in his hands were extremely terrifying, so he and his subordinates, each of them had their own troop system, and the most basic maintenance system was a particularly high-end variety.

According to the current statement, the basic class of Danmaku Ji is a miniature robot, and because it doesn't need to fight, it's just a black iron variety.

And the basic class of the dragon cannon Ji is the liquid metal velociraptor dragon, which belongs to the bronze level of the class, with strong attack power and stronger defense, except for the skeleton, the others are liquid, almost completely and almost completely harmless.

The most important thing is that this thing can repair more advanced metal varieties by throwing out the liquid metal on its body.

So this is a kind of logistics arm with strong combat effectiveness.

As for Emperor Shi Tian, not to mention, his basic logistics class is a humanoid battle ji, each of whom is assigned a high-level mecha more than ten meters high, and if one cannon goes down, a building will be gone, and it should be a silver variety even if it is counted here.

Compared to others, Princess Lionheart's flywheel robot is really really a garbage class.

Seeing Emperor Shitian's rare embarrassment, Princess Lionheart's anger suddenly disappeared, and then she helplessly grabbed the little rabbit and said, "You don't know what basic troops these local tyrants use?

"This~" When the little rabbit heard this, he was speechless, and couldn't help but say hatefully: "Damn local tyrant!"

"That's all in the past!" Emperor Shi Tian hurriedly said: "Now we are all in a group, I am a local tyrant, and you are also a local tyrant?"

"Then you'll have to help us make a sufficient number of flight attachments!" said the little rabbit at once.

Emperor Shi Tian didn't hesitate, and said directly: "If your flywheel robot can really fly, then I can fully support your plan!"

You know, the reason why flywheel robots are garbage is because in the rugged underground world, it is easy to go wrong, which increases the cost of operation.

And if you want to get rid of this shortcoming, the flywheel robot is actually very good, especially its accurate long-distance shooting ability, which is very coveted by Emperor Shitian.

If these flywheel robots can fly in the sky, it means that Emperor Shi Tian has an extra powerful air unit, and it is also an air superiority class, and it is the best flying unit to deal with the enemy.

Because of the flywheel robot's long-range accurate shooting ability, coupled with the firepower advantage of eight arms, it can definitely defeat the flying class with weak defense.

Even the dog-headed aluminum bat in the hands of Emperor Shi Tian is not an opponent against the flying flywheel robot.

No way, who called the range of the dog-headed aluminum bat too close?

Princess Lionheart didn't talk nonsense, and directly took out a design drawing to show Emperor Shi Tian.

After Emperor Shi Tian browsed it, he found that this attachment was really not simple, it actually needed to use the magic metal of the wind system, and to create a large ring, and to depict the flying circle,

In addition, although it barely flies, the speed is touching, and the fastest is only more than 100 kilometers per hour, and it is not even as fast as the dog-headed aluminum bat.

The most important thing is that the magic consumption of the flywheel robot will increase significantly, resulting in a very short range, which can only be a thousand kilometers at most.
