"Oh!" the queen said strangely: "What's so good about Smelting Iron?"

Robb smiled and said: "Didn't you say last time that I wasted a lot of iron in the auxiliary rails in the mine? I'm going to let you see if this kind of rail is a waste of iron."

Hearing what he said, the queen remembered the topic of the last time. After dozens of days have passed, her majesty has forgotten too much, and almost forgot about it. Now listen to what he said, hurry up. Corrected my sitting posture: "That's it! Then I'll take a look, this is also a very important business."

She turned around and said to the necromancers and civil servants around her: "You should also let go of the government affairs in your hands. Let's take a look at Robert's new invention with this king. Although I don't understand his invention this time, I don't really understand it. Judging from the things he invented in the past, they are all very interesting things."

In her words, there is also a hidden meaning, that is: to learn secretly!

It turned out that the officials standing next to her were all officials in charge of internal affairs. One of them was in charge of the management of the Guangming Road Royal Water Plant, and this water plant was Robb’s invention.

As soon as the queen said this, the official in charge of the water plant immediately understood the meaning and stared at the crystal ball earnestly.

And there is an official next to him, who happens to be the official in charge of "arms". He manages the entire Siglan metal smelting industry, weapon manufacturing industry, and even all the craftsmen of Guangming Road. He is under his jurisdiction.

The official immediately became interested, and fixed his eyes on the crystal ball.

Robb shrugged, and said in a weird manner: "Miss Queen, I gave you a private call, but you asked two big men to stare at me, what's this?"

Her Majesty the Queen has long been accustomed to the weird words about him, and she just treated it as if she hadn't heard it: "Now, please start your performance."

"Tsk, it's boring! Okay, I will show you the situation on my side first."

Robb lifted the crystal ball high, allowing the field of vision on the other side to be wider.

Her Majesty was sitting still, but the officer in charge of armaments immediately saw a huge furnace next to it, the blast furnace...only the outside could be seen, but the structure inside. But for this kind of technical official, you don't need to look at it to know what structure is inside.

He whispered: "Your Majesty, this is an iron-making furnace, but it is much larger than the furnace used by our blacksmiths, at least one hundred times larger. As far as I know, there is no such large furnace in the human world. Only the dwarf craftsmen in the ground would build such a large furnace to use."

Her Majesty's face showed a confused look: "Why do you make such a big stove?"

The armament officer whispered: "The bigger the furnace, the more ore can be smelted at one time. It's just that...just like this, it is more difficult to heat up the furnace. The dwarves usually use lava from the core of the earth to heat the furnace. We can’t borrow the power of lava. We can only use magic to raise the temperature of such a large furnace. The proud fire magician disdains to help people make iron... Besides, our iron ore output is already there. Not enough, and there is no need to send out a fire magician to heat such a large furnace. If he puts up such a large furnace, he must have a very high output of ore."

Her Majesty nodded, she understood.

She has long been reported that Robb owns a robot that mines fast, but according to report No. 8, every time that robot is used, something called "gasoline" is consumed, and Robert has very limited gasoline. , He was reluctant to give all the gasoline to the robot, and the robot was already resting.

Her Majesty the Queen said indifferently to the crystal ball: "Mr. Robert, if you build such a big stove, you must dispatch your mining robot to continuously provide ore for it, and you simply can't bear to use the little remaining gasoline in your hand. , Don’t you think that this big furnace is a bit of a great success?"

Robb smiled and said: "I don't use that robot, I just use the power of the miners to continuously get a lot of ore with energy, believe it or not?"

The queen smiled slightly, not to believe or not to believe, not to give him a chance to win, nor to give him a chance to slap herself in the face.

But the armament officer under her command was not so smart. He stepped forward and said to the crystal ball: "You don’t believe me! A miner wants to smash a piece of ore in the mine with an iron pickaxe, and then remove it out of the mine. It’s a cumbersome process, and it’s not going to get up quickly. Even if you put in a lot of manpower, it’s not as crowded as it is in a small mine. Maybe it’s crowded, but it makes it slower."

Robb smiled: "Interesting! Miss Queen, you are not kind, you don't want to be slapped by me, so you hide behind and ask someone to come out and block the knife."

The queen smiled and said nothing.

"Forget it, what a ghost woman." Robb took the crystal ball and walked to the entrance of the mine.

As soon as he got here, the military officer saw through the crystal ball that there was a railroad track on the ground, with sleepers underneath, and the upper track was made of high-quality fine iron. It was beautiful and thick, and it was not a single track. Double track! These two thick rails extended from the mine, and protruded out of the mine for nearly ten yards long.

"Ah, how much iron is used." The military officer was distressed: "So much iron is actually used to supplement the ground."

"This is not a supplementary land, it is used to guide the minecart." Robb pointed to the end of the track. There was a string of minecarts parked there. There were two wheels underneath the minecart, which were buckled on the two rails. It is a pallet-like body with a hollow inside and looks very fit.

The minecart and the minecart are connected by iron hooks, which can be broken apart at any time, and can also be connected together at any time.

There are two long ropes attached to the mine cart, and there are several bells hanging from the rope.

Seeing this, the armament officer fell into contemplation. After ten seconds, he opened his mouth and said: "Using the track to speed up the operation of the minecart and reduce the friction of the minecart moving in the mine? This is interesting! With this thing, it is indeed more convenient to transport minerals, but... the mine cart full of minerals is very heavy even if it is towed by the track. It’s uphill, how much manpower is needed to propel this car?"

Robb laughed and said: "Yes, not bad, you are a technical person, you can understand the principle of the car and the track at a glance, but you still don't understand the meaning of laziness, just save manpower as much as possible, and you will know how I am in a while. Get this car up from the depths of the mine."

He turned around and laughed loudly at the jobs guarding outside the mine: "It's ready to start."
