Hearing this, the old blacksmith was dumbfounded for a moment, thinking hard.

Because Robb deliberately mentioned the fan, the old blacksmith first thought of the fan blade that was spinning so hard to see. Then he heard Robb say "big wheel", and he naturally thought of one in his head. Wheels that keep spinning.

People have been pointed to this point, if he still doesn't understand, then it is really worrying about IQ.

The old blacksmith's eyes lit up: "Wheels that turn on their own? This...this...is...the minecart that can run on its own?"

"Haha, not bad, you are quite smart." Robb smiled.

The old blacksmith thought about it carefully, and couldn’t help thinking about it, the more he became happy, but after he was overjoyed, he said sadly: “Godfather, it’s no good, the engine is too huge, big and heavy, the kind of small mine that can only hold one person. The car is not as big as our engine, so it can’t fit in a minecart.”

"So, build a huge car."

Robb brushed the floor and took out a drawing, gave it to the table, and said with a smile: "Look, this is a drawing I drew a long time ago. This thing is called a'diesel train', and its locomotive is very huge. It’s not a problem to install a diesel engine inside, and it’s okay to install several engines to target different tire groups.”

The old blacksmith looked at the drawing and immediately understood that this is obviously an "upgraded version of the big minecart". There is a huge locomotive in the front. There is not much space in the locomotive. There are many carriages, and each carriage is drawn squarely. It seems to be used to hold things very well. Moreover, Godfather also deliberately painted several carriages like carriage carriages, that is to say, Godfather also intends to put people in it.

"This... such a big car, can our diesel engine be able to move it?" The old blacksmith was a little unconfident: "Even if it can be moved, it will run very slowly."

Robb said: "If you can afford a boulder, of course you can drive a car. If you can plug in a few more engines, the speed may not be fast at first, but with the continuous improvement of technology and the continuous improvement of the engine, it will run more and more. Fast."

The old blacksmith nodded and said that he understood, but he still had a problem: "The 150-mile-long railroad track will help out. This is a good iron with 150-mile length. Someone or a monster will steal our railroad track. Good steel, if it is stolen, we will lose a lot..."

Robb smiled: "So, at first, it’s okay to drive the car slowly. The driver saw that the rails in front had been stolen, and he had time to stop quickly, so as not to cause an accident. Then, quickly repair the rails and the car will do. Keep going. As for those who dare to steal our railroad tracks, hand it over to Chief Elsie, oh, no, it’s Chief Elsie to clean it up, hahahaha."

"What's the use of such a long rail and minecart to go to the original stone canyon?" The old blacksmith was puzzled.

Robb said: "It's useful, but I'm so lazy, too lazy to explain, you will know it naturally in the future."

The old blacksmith heard that Godfather had moved out the word lazy, so there was nothing to ask. Godfather who initiated the laziness was simply frantic, and wanted him to explain to himself in lengthy terms, it was impossible.

He had to obediently said: "Then I will go back and arrange for the apprentices to build railroad tracks and let the students in the carpentry class make sleepers. In addition, I will bring some of the best craftsmen to study how to make locomotives."

Robb smiled and said: "Okay, do it as soon as possible. The most difficult part of the locomotive is the engine. Now that the engine has been fixed, there should be no difficulty in other things. There is no need to pay attention to beauty. The little train is right when it comes out."

"Okay!" After the old blacksmith saluted him, he hurriedly went.

Robb was about to be lazy, and suddenly he saw from a distance a slim figure walking over on the small road in front of the church, who was actually the daughter of the Minister of Court Affairs.

This woman is No.1 among the top ten flowers of the Magic Academy. She is still pretty, a gentle water magician, but Robb looks at the crystal ball every day to see Miss Queen, the first beauty of the Kingdom of Gran, compared to what No. 1 in the Academy of Magic is not a level, so this poor school girl has never been able to get into Robb's eyes.

She walked to the front of the church, saluted Robb, respectfully: "Godfather, good evening."

Robb must pretend not to know her, so he put on a curious face: "You are?"

"I came from the bright road." She respectfully said: "I came to greet you with my classmates at noon, but there were so many people at that time, you might not have noticed me."

"Oh oh oh!" Robb pretended to suddenly realize: "What can you do for me?"

The palace minister’s daughter blushed: "Well, I...I came to see Robert. I am unfamiliar in the town of Westwind, and I don’t have a friend, so... I want to talk to him and take a walk with me. "

Ghosts have time to talk to you. Robb deliberately put on an old-fashioned look, and opened the preaching mode with a hearty tone: "What steps to take? You young people, you know to be lazy! Do you practice magic spells? Do you meditate on magic? Is the magic rune memorable? Isn’t it? Robert didn’t have time to talk to you. He is now carrying a wind magic book in the church. It is impossible to find him to play. As his mentor, I will not let him and you unlearned bad boys. Play!"

Daughter of the Minister of Palace Affairs: "..."

Freeze!

After dozens of seconds, she aggrieved Barra and lowered her head: "Then I'm leaving! Excuse Godfather."

She turned and left, and the setting sun dragged her lonely back to the old man, looking bleak and desolate.

Robb's heart is secretly happy: Hey! Eliminates a two-wire operation.

Just thinking of this, another figure came over in the distance. It was Marian. She and the court minister’s daughter passed by, walked to the door of the church, and gave a salute to Robb: "Godfather, good evening."

Robb cursed in his heart, another one?

But it's okay, as many as they come, just stop them.

"You also came to see Robert?" With a serious face, he slapped and said the line that he had just said to the minister of palace's daughter, and finally added: "You bad boys , Don't influence Robert's study anymore."

"Hey? Godfather, you misunderstood." Marianne smiled: "I didn't come to see Robert. I just have a cooperative relationship with him. On a personal level, I have never played with him, nor do I have any special feelings. ."

Robb Daqi: "Then what are you doing here?"

Marianne smiled and said, "I'm looking for you."
