The Queen’s military officials were surprised by the equipment at the same time, and at this time, they finally understood the meaning of the auxiliary rails.

"The minecart is not driven by manpower, but the power of the machine, and the power of the machine is relatively rigid, unable to flexibly turn and guide the minecart, so it is necessary to make a railroad so that the minecart can only walk along the track. In this way, as long as a force is given in one direction to drag the minecart, it will follow the rails and run up from the deepest point of the complex mine." The military officer couldn't help but exclaimed, "My Darkness God, what a brilliant idea! I now understand that the rails on the ground are not wasted at all. They can indeed bring more iron. This is a very cost-effective investment."

The queen was also a little surprised, but the king of a country kept her grace and demeanor. She did not scream like an armament officer. She turned her eyes to the one that could pull the winch and wink more than a thousand catties. The strange machine of the minecart asked: "This is the most important thing, right? If there is no such thing, at least a dozen workers must be arranged outside the mine to tow the rope to pull the minecart up."

Robb laughed and said: "Miss Queen Sister really has a vision. Things like railroad tracks and mine carts are all skills that you can handle. Only this machine, hehehe, it saves time and effort. The point is, hey, in fact, it is the mining robot in your intelligence."

"Mining robot?" The queen was shocked: "Isn't it for mining? Did you change it to a cart?"

Robb spread his hands: "To be precise, I took it apart!"

It turned out that Robb immediately dismantled the mining robot WK0032 after trying it out. Because this thing will grab the jobs of the miners, if it keeps mining, the miners in Xifeng Town will not be able to live anymore.

Moreover, Robb does not want this "game technology" to affect the world. After all, mining should still be done by miners. At most, we will study some electric mining tools or excavators in the future, so that miners can save a little effort. , But it’s better not to rely on things like “mining robots” that obviously have “plug-in ideas”.

What he has to do is to "guide" the townsfolk of Westwind to an advanced society, rather than lead them into the open world.

Because it was just a momentary pleasure, when Robb was really pulled by Xueluo to clean the Demon King City, without Robb’s plug-in, Xifeng Town would instantly become a second-hand place.

If you don't rely on plug-ins, accumulate technology at every step, and move forward steadily, then no matter how far Robb leaves, Xifeng Town can continue to move forward with its own technology accumulation.

Therefore, he returned the work of mining the ore to the miners, and after the robot was disassembled, it only used its engine components to pull the mine cart. Anyway, the use of the machine to pull the mine cart can be achieved without much use. This is not very Serious plug-in. Even if you don't need to generate power and use a few more manpower to rotate the gear set, you can still lift the weight with ease.

Therefore, Robb dismantled the hands, feet, and head of the mining robot, took out the "engine assembly" from the robot body, and then connected the engine assembly to a gear set and turned it into a mine entrance. The machine that pulls the minecart.

The queen looked at the engine with an unhappy expression...

She is not stupid. She knew at a glance that she could imitate the rails, minecarts, and even gear sets in front of her. Only with this strange engine, she knew she could not imitate them. If she wanted to play, she had to pay Robb again. Money.

But after seeing the high-efficiency method of digging and transporting ore, how can it be possible to accept the old and backward method? The queen could only admit it, and sighed: "How much would you sell me this thing called an engine?"

"No!" Robb smiled: "Even if it is really sold to you, you can't play it. It needs gasoline as fuel, and you can't make gasoline. Even if it's me, I want to stabilize the output of gasoline. It's not easy, so... this engine can only be regarded as a "concept technology" and cannot be promoted. You should use manpower, or cattle or horses to pull it! Anyway, even if you use manpower to pull the railcar, the efficiency is better than before. Improved a lot."

The queen was silent.

"Okay, the next step is to watch the smelting step." Robb jumped out of the minecart, returned to his wheelchair, and then smiled and said to the workers who were waiting next to him: "Unload the cargo, take the iron ore Unload it on the conveyor belt and send it to the smelting furnace!"

At this time, the queen and the military officer discovered that there was a strange thick rubber belt beside the rails. It was very long and wide. It stretched out like a piece of cloth until it reached the high smelting furnace. It seems that this is the so-called The "conveyor belt" too.

Several workers guarding outside the cave came over and opened a board on the side of the mine cart. The ore in the mine cart rolled out and fell on the "conveyor belt". Then the workers turned a crank and the thick rubber belt started. Turned up and carried the ore to the blast furnace.

There is a small window on the blast furnace, and all the ore is dragged into the small window by the conveyor belt.

The queen and the military officer looked confused...

In fact, the conveyor belt technology is really not a very sophisticated technology. The two of them can understand what to do at a glance. Even if they don’t have rubber, they can use other materials instead, such as wood, iron mesh, and copper. Nets and even cloth belts can be used. They just never thought that they could still transport ore like this.

I saw that the several large carts of ore that had just been transported were continuously being sent into the blast furnace, and, while the conveyor belt was transporting the ore, the mine carts were once again put into the mine.

Due to the existence of the railroad tracks, the minecart almost went down to the bottom of the mine in a blink of an eye. The miners filled them with ore in a blink of an eye, then rang the bell, and the engine on it turned on. A cart of ore was pulled up and poured into the conveyor belt.

The queen and the military officer watched as thousands of catties of ore were sent into the blast furnace.

Robb laughed loudly: "Okay, turn off the smelting furnace! Ready to start smelting."

With an order, the workers quickly shut down the conveyor belt, moved away from the smelting furnace, and lit...

A raging fire burned in the smelting furnace.

At this time, the queen and the military officer also seemed to have awakened like a dream. The two looked at Robb together: "Such a big stove, heating by ordinary methods won't work, what else can you give such a big stove? Is the stove a new invention to raise the temperature of the stove?"

Robb spread his hands and said helplessly: "Not yet, so..."

He turned his head and said loudly to Xue Lu next to him: "Xue Lu, do me a favor."

Xuelu cast a wink at Robb, and then chanted a spell. It didn't take long for a wall of fire magic to be put into the stove...
