After Maxing out all Classes

But after seeing that kind of efficient method of digging ore and transporting ore, how can she accept the backward old method? The queen can only admit defeat, sighed and said, “how much do you sell this thing called engine?”

“It’s not for sale!” Robb said with a smile, “even if I really sell it to you, you can't use it.
It needs gasoline as fuel, and you can't make gasoline.
Even for me, it's not easy to stabilize gasoline production, so…
This engine can only be regarded as a 'concept technology' and cannot be popularized.
You'd better use manpower, or cattle.
In any case, even if you use manpower to pull the carts, the efficiency will be much higher than before.
“

The Queen remained silent.

“Well, the next step is to see the smelting step.” Robb jumped out of the mining cart and returned to his wheelchair, then smiled and said to the workers who had been waiting for a long time, “unload the iron ore on the conveyor belt and feed it into the smelter!”

At this time, the Queen and the officer discovered that there was a strange thick rubber belt beside the track, which was long and wide, extending like cloth, all the way to the big smelting furnace.
It seems that this is the so-called “conveyor belt”.

Several workers outside the cave came over and opened a board on the side of the mine cart, and the ore from the mine cart rolled out and fell on the “conveyor belt”.
Then the workers turned a handle, and the thick rubber belt began to run and put the ore to the blast furnace.

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

The Queen and the armaments officer looked confused.

In fact, the conveyor belt technology is not really a very complicated technology, the two of them knew at a glance what to do, even if they did not have rubber, they could replace it with other materials, such as wooden boards, iron and copper nets, or even cloth belts.
They just never thought they could transport ore in this way.

They saw that the several carts of ore that had just been transported were continuously sent into the blast furnace, and while the conveyor belt was carrying the ore, the mining cart was once again put into the mine.

Due to the existence of railway tracks, the mining cart almost instantly went down to the bottom of the cave, and the miners filled them with ore in a twinkling of an eye, then rang the bell gear, and in less than a few minutes, another cartload of ore was pulled up and poured onto the conveyor belt.

The Queen and the armaments officer watched helplessly as thousands of jin of ore were sent to the blast furnace.

Robb laughed loudly, “all right, turn the conveyor belt off! Get ready to start smelting.”

At the sound of the order, the workers quickly closed the conveyor belt, brought it away from the smelting furnace, and lit the fire.

The fire burst into bigger flames in the smelting furnace.

At this time, the Queen and the armaments officer seemed to wake up, and they looked at Robb together, “it's impossible to heat such a big furnace by ordinary methods.
Do you have any new inventions that can raise the temperature of such a big furnace?”

Robb shrugged and said helplessly, “not yet, so…”

He turned to the nearby Xuelu and shouted, “Xuelu, do me a favor…”

Xuelu winked at Robb and chanted.
It didn't take long for a firewall to be put into the furnace.
