Robb got out of his wheelchair and got into a mine cart, like a child sitting in a supermarket shopping cart. There are several of this kind of minecarts connected together, just like the multiple carriages of a train, Robb alone takes up a whole section.

As soon as he sat like this, Her Majesty the Queen couldn't laugh or cry: "Are you planning to go down to the cave in a minecart?"

"Yes!" Robb said.

"Can you be more lazy? You can't walk in with your feet?" Her Majesty said grumpily: "If my men had not witnessed you standing up and walking many times, even I would think you are a great mage with a broken leg."

Robb smiled and said, "This time it's really not laziness, but the walking speed, which is far from keeping up with this car."

He said to the worker who manages the pulley block next to him: "Okay, let me go down the hole."

The worker smiled and said, "Okay, Godfather, please sit down."

After speaking, he slammed down a rocker.

A buckle stuck on the mine wheel bounced off, and the mine cart immediately slid forward. The rail is inclined from high to low to extend down the hole, so once there is no mechanism to catch the wheels, it immediately starts to slide down the rail.

Gliding very slowly at first, slowly sliding into the mine.

Robb opened a holy light technique casually, illuminating the mine like daylight, while Her Majesty the Queen and the military officials on the side of the crystal ball watched the minecart slip continuously into the mine through the crystal ball.

"It's a long railroad track." The military officer looked at the railroad track that continued to extend deep into the heart of the earth, feeling extremely painful. If this iron is used as a weapon, how many swords have to be made?

I saw that the minecart was sliding faster and faster, and the walls of the cave were constantly slicing across both sides. Robb’s hair began to be lifted back by the wind, and he suddenly started to get excited: "Hahaha, it feels like a roller coaster, it’s cool. Cool……"

Her Majesty the Queen and the military officer on the side of the crystal ball stared at the screen, like playing a roller coaster game through the monitor. After a while, she felt a little dizzy in 3D. The queen covered her forehead and said, "Oh, this screen looks at me. Dizziness."

The military officer also said: "I think I need to close my eyes for a while."

"It's going to the center!" Robb smiled: "Look at it."

The queen and the military officer hurriedly took a closer look. It turned out that at this time the minecart slid to a transportation hub in the center of the mine. There were many torches. A worker was waiting at the place where the railroad tracks crossed. He saw the minecart coming. He made a gesture to Robb, and then flicked the joystick in his hand.

The track was bridged again, Robb’s minecart turned around, and continued to slide down into a forked mine next to it, and quickly slid to the deepest part of the mine, at the end of the track. With a thick piece of rubber, the minecart hit the piece of rubber and stopped.

Then, the picture finally did not change rapidly.

The queen and military officials who were a little dizzy in 3D can finally look at the situation inside. I saw that this is a huge mine. There are dozens of miners digging ore here. They have obviously been digging for a while, and the ground has been A lot of iron ore is piled up.

Robb smiled at the crystal ball and said: "This is the ore they dug up all morning. Because they have been only doing ore mining, they don’t need to carry the ore out of the hole by themselves, so the efficiency of mining is very high. , So much has been dug out."

The queen smiled.

The military officer said with a slanted face: "Are you going to load these ore on a truck now?"

"Bingo!" Robb smiled: "Look at what they do."

I saw the miners who were digging temporarily stopped mining, turned around and picked up the ore dug out in the morning from their feet, and put them in their carts. After a while, they filled up one mine cart, two mine carts, and three mine carts. Minecart...

The minecart, which was connected in sections like a small train, was filled in an instant. Only the car with Robb was not loaded with stones, because it was already loaded with a lazy Godfather, and obviously could not load any more ore.

The armament officer silently estimated that six vehicles, five were loaded with iron ore, and one was loaded with a man weighing more than one hundred kilograms. The weight of the entire convoy would be quite impressive. Above a thousand five hundred catties.

He was a little puzzled: "How do you get such a heavy convoy back to the ground? When it slid down just now, it slid faster and faster. It can be seen that the mine is deep and there is a considerable distance from here to the ground. How many people does it take to push a heavy convoy?"

Robb smiled, grabbed a rope dragged on the tail of the car, shook it vigorously a few times, and smiled: "When I shake the rope like this, the bell hanging outside the mine will ring, and then, the outside People will pull us out."

"Isn't it pushing, it's pulling?" The armament officer was a little curious. When he went down the cave just now, he saw a few workers staying outside. Those few people wanted to pull up a convoy of more than a thousand catties? I'm afraid it's a bit unrealistic.

As soon as I thought of this, the rope hanging on the tail of the car collapsed. It seems that someone was pulling outside, so the rope would collapse first.

However, the armaments officer really didn't think that this rope could pull a car weighing more than a thousand catties out of the hole.

However, he was taken aback by the facts. After the rope collapsed tightly, he suddenly began to recover. Then, the caravan filled with ore and Robb actually slid along the rails toward the road, slipping faster and faster, and slippery faster.

The armament officer yelled "Ah": "I see, someone outside is using magic, or a hero of infinite power is pulling a rope."

Robb smiled and said: "No, there are just a few ordinary workers guarding outside."

"Hey? Hey! No, my head is dizzy again."

The picture in the crystal ball flashed rapidly, and the scenery on the two walls of the mine couldn’t help retreating. The queen and the military officer began to faint in 3D again. After a while, the entire mine cart rushed out of the mine. Back on the ground.

The armament officer immediately looked at the crystal ball for the first time. I didn't know it. He was shocked when he saw it. There was really no magic, and no strongman was pulling the rope outside. Only the few workers who were operating a strange machine just now made a roaring sound and pushed a crank.

The crank drove a small wheel, and then the small wheel drove a larger gear, the gear drove a larger gear, layer by layer, and finally drove a huge winch, the winch rotated, unexpectedly easily He pulled up a convoy weighing more than one thousand kilograms, and quickly transported the long string of mine carts and the ore back to the ground.
