Seeing the dumbfounded faces of the two of them, Robb did not explain, and smiled and told Lilian: "Go to the smelting yard and let the workers bring me two thousand five hundred catties of iron. That's right. I need a small cart of coal."

"Two thousand five hundred catties?" Probo and Elsie were taken aback by this number: "What weapon requires so much iron?"

Robb spread out his hands: "Heavy weapons! Don't you feel that the fifty thousand demon king army is under a lot of pressure? I will get you some heavy weapons so that you don't have to be afraid of the fifty thousand demon king army."

"This...this is too heavy." Elsie said that the pressure is greater than that of the fifty thousand demon king army: "Such a heavy weapon, the officer can't handle it."

"Cut, who wants you to hold it in your hand and wait and see it quietly."

He scolded Elsie with a smile, and gave Lilian a sprint. After a while, Lilian went to the smelter, and then, one by one, transporting iron pieces came over. Two thousand five hundred catties of iron is not light. The workers used several vehicles to get it. The iron ingot was squarely formed into a cube in front of Robb.

So much iron is not surprising to Elsie, but Probo has not seen the rapid development of Westwind Town because he travels north to do business, and now he can take out so much iron when he sees Westwind Town. Ding was slightly taken aback, thinking: Now Xifeng Town has become an unknown town.

"Okay, now I'm ready to start production!" Robb smiled: "The high-end engineering mount of "Black Blade"!"

Use "thorium ore" to make...four "thorium ingots".

Then he fetched things from the air. The "dense sand and gravel" that Maturo helped him last time flew out of the warehouse and fell in front of him, using the "dense sand and gravel" to make... "dense grinding wheels".

Then use "thorium ingot" and "dense grinding wheel" to make... "precision thorium parts".

When two "precision Thorium parts" appeared on the table, Probo and Elsie almost went crazy on the spot, Thorium! The extremely rare and extremely precious metal is actually used to rub two small parts. What is this? It looks like a gear, but not quite like a gear. What the **** is it?

However, the two of them were not in a hurry to complain, because they all knew Robb's ability and would not have any doubts about Robb before things became clear. They were suspicious of their own vision.

Robb pointed at the pile of iron ingots again...

Use "gold" to make..."golden energy core".

Then use "iron ingots" to make..."steel ingots".

Use "steel ingots" to make..."steel shells".

Finally, use "steel shell", "golden energy core", "precision thorium parts" to make...

This time the production time has become extremely long. Elsie and Probo only saw Robb’s hands rubbing and rubbing them for a full twenty seconds, and then he pre-rubbed them just now. That bunch of messy things, all merged together, and then turned into a huge, weirdly shaped cart.

This car has a row of wheels. The wheels are not wrapped in the rubber that Robb likes. Instead, they are wrapped in a strange track with a round head on which a long cannon barrel protrudes.

Even if Probo was well-informed, he had never seen this weird thing.

Captain Elsie couldn't help asking, "What is this? Is it a miniature train?"

"No!" Robb smiled: "The name of this thing is-Steam Tank!"

It’s also interesting to say that Robb has produced a “diesel engine” and even a “diesel train” by disassembling parts from the mining robot WK0032, but because he has not obtained Thorium, he has never To make a steam engine, this time I finally have Thorium before I can make a steam engine.

It is simply a retrogression of technology!

However, there is such a wonderful engineering setting in the game.

Fortunately, people in this world don't understand steam engines and diesel engines, and they don't know that he is playing with the concept of retrogressiveness.

Robb stood up, opened a small door on the belly of the steam tank, and asked the workers to stuff coal into it, and then add water to the water tank. In this way, the preparations were all alive.

Elsie and Probo are already stupid, but neither of them are really fools. On the contrary, they are much smarter than most ordinary people in this era, and they can already guess this big iron car to some extent. What are you doing, it's just not sure yet.

Robb lifted the top cover of the tank and got in.

The steam tank has been played many times in the game before, but it is the first time to experience it in the real world. There are a bunch of messy instruments in the tank, basically I can’t understand it, because the operation method in the game is the keyboard. , After this thing is actually made, the way of manipulation has changed.

It doesn't matter, just press it.

Fumble and fumble with one pass!

Fortunately, Robb is a modern man after all, even a machine that can't operate at all is not too difficult to be blinded. After a while, a small whistle sounded above the steam tank, and then the huge tank moved...

Elsie said loudly, "A big railcar that can run without railroad tracks, the **** of new light."

"Huh?" Probodaqi: "What the **** is the New God of Light? Why is there a new word in front of it?"

Now is not the time to entangle this kind of thing. I saw that the huge tank has already started to move. It rushed out of Robb’s yard, knocked down a section of the fence, and turned around in the open space in front of the church. He turned his head, his head turned, and the long barrel pointed at the hillside behind the church.

Then……

"boom!"

The main gun fired!

A goblin rocket spewed out of the tank's barrel and flew towards the hillside ahead, and then exploded with a "boom", dust flew in the sky, and a huge crater was blasted out of the hillside. The huge sound attracted a large group of nearby townspeople to surround themselves, and everyone was pointing at this weird big iron car.

However, everyone knows that this must be Godfather's masterpiece again.

Robb fired only one shot, pushed open the top cover of the tank and came out, waved at Elsie, and smiled: "How about? Give your troops two hundred of this stuff, you have Do you have confidence to deal with an army of fifty thousand monsters?"

Commander Elsie was already stunned by the shot. He looked at the big hole on the hillside in the distance, then turned around and looked at the huge iron wagon, suddenly excited: "The perfect combination of offense and defense! It's amazing. This thing is too powerful. If there are two hundred of this thing, the Demon King's army is a ball."
