It looks like a bad toy, but it is full of infinite possibilities.

After seeing the tracks that Rowling had laid on the ground and the appearance of a simple toy train that was moving forward with a small boiler.

Roland felt another surprise.

I wish I could hold the white-haired home girl squatting there in the little maid's uniform and chew on it a few bites.

Too awesome!

Rowling's general direction is the right thing to do now, and she has not taken the wrong route. The remaining tasks are just as long as they slowly improve the mechanism problems.

This is not a surprise like backstab, Roland is genuinely happy.

"Rolling, are you doing all this?"

Roland squatted down next to his white-haired home girl.

"Um!"

Rowling first showed a sweet smile at her Demon King, then looked at her little toy with a frown and complained: "Well, are I stupid, Lord Demon King? I haven't been able to let the wheels walk on the ground after studying for so long."

After saying that, she put on a more aggrieved look on her face, and she might be worried that the Demon King would blame her.

"No, no! Rowling is not stupid at all! You are very smart! You are doing a great job!"

Roland was excited and hugged the white-haired home girl and kissed her white cheek.

This was the first time Roland did this action, which made the white-haired homegirl feel a strange feeling.

She covered the kissed place, her cheeks were burning, and she looked at Roland with her head tilted and didn't know what she was thinking.

Roland continued to get excited: "Rolling, can you tell me what you think now?"

Roland asked, pointing to the prototype of the train that was still moving on the ground.

“Hey hey~”

After hearing the question from Lord Demon King, Rowling recovered from that stupid image, and her silver eyes were full of energy.

He nodded for granted: "Well, as Lord Demon said, I thought about using the power generated by steam and using the transmission device to monetize this energy. I just wanted it to push the cart forward."

Halfway through his speech, his pretty face became slapped: "But the resistance on the ground is too great, and the steam is not strong enough. It can only be placed on this track to facilitate progress."

The problem Rowling encountered was also very simple, but the steam engine was not closed enough and the steam generated could not be fully utilized.

To put it bluntly, it is a matter of efficiency.

This problem is not difficult, and it can always be solved in the process of slowly improving it.

Just like during the industrial revolution in the previous life, the steam engine was improved in various ways, and its development speed exceeded the historical accumulation.

"You are not in a position now. Think about it, can you reduce the existence of resistance in this track? You can make the wheels turn faster when moving forward."

"But it can't move forward on the ground."

"It's okay, think about it, we can lay this kind of track between two destinations so that it can move forward."

After hearing Roland say this, the white-haired home girl showed an expression that could have been like this.

It has been said before that her witch's power is a bug, which also leads to this girl's ability to do things is relatively strong.

There was no special movement of Rowling. After the tracks on the ground dispersed by themselves, they began to slowly reorganize, and soon formed a straight line between the two points.

She put the prototype of the train on again.

"Look, now it is just a front of the car. After you expand its steam power, can you pull more cars behind it? If each car is filled with goods, it will be the most important tool of the Demon King City!"

Roland encouraged Roland.

"Um!"

The white-haired home girl is also full of motivation.

"Royling is amazing, what reward do you want?"

Roland decided to reward her white-haired homegirl.

After hearing the reward, the silver eyes became even brighter.

"I want the Demon Lord to play with me!"

An expression of expectation.

"Forehead."

Rowling's request was too simple. This high return and low demand made Rowling feel like a black-hearted capitalist.

"Is there anything else?"

Roland stood up and said, touching the girl's white hair.

Rowling leaned on his devil, held his waist, rubbed his palm and made another request: "Well... eat delicious food!"

"Okay! Let Lilith make a delicious meal for you tonight."

Roland was really amused and crying. This white-haired home girl was so easy to buy.

If you want to talk about the most fun place near Demon King City, of course it is the production area.

Due to the mobility of workers, it has become an extremely mature market.

The market content is mainly about food, and white-haired homegirls will definitely get used to it.

After leaving the Demon King City, holding the white-haired home girl's little hand, the two of them slowly chose to walk to the north.

Mainly, after growing up with the Succubus Secretary and the Duke, this kind of intimate behavior is completely a subconscious behavior.

In the past, he would not hold her little hand intimately even if he took a white-haired home girl to play.

For the white-haired home girl, the devil's actions made her very happy.

The corners of his eyes were smiling into a crescent-like shape.

Her walking pace also became happy, with white silk wrapped around her calves. She would deliberately kick the corner of her skirt when she walked, kicking the black and white maid skirt very high.

This also makes Roland have an illusion that he feels like he is picking up his child from school.

Rowling is a primary school student who just got 100 points in the double exam, and he walked away from the pace of not recognizing his relatives.

After walking for a while, Roland asked Roland to quickly take him to another production area.

After all, I am here to play, so it doesn’t make sense to waste all my time on the road.

On the way, Roland also told the White-Haired Housewife a new concept.

"Look, if you follow your method and lay that kind of track in the Demon City and the production area, we can take the train you are studying."

The name of the train was started by the White-Haired Housewife.

Some of the behaviors of the white-haired homegirl made Roland feel that she was more like a time traveler than herself.

If it weren't for the Demon King's power, even they could buff, Roland would have suspected that he was not the protagonist at all.

The ability of gold fingers is not as good as others.

The entrance to the Northland Production Area is a very mature commercial activity. In the words of the earth, it has become an exclusive snack street.

The roadside stalls were all set up.

Roland told the local sheriff not to worry about his comfort, and to continue to stay at work without having to specifically protect himself.

When the sheriff saw the witch following the Demon King, he agreed to the request.
