Is the castle lord really the one on the mountain?

Sledgehammer fell into frantic thinking, completely ignoring the existence of everyone.

It's just that he couldn't understand how the dignified 98 City Lord could run to a remote mountain peak and still deal with major life events?

Thinking of this, he instantly denied his own idea.

I must have seen it wrong, not to mention that there are more people with similar backs.

Seeing him in a daze, the city lord Sima Pingping said again: "Boy, what are you thinking?" ”

Lei Sledgehammer came back to his senses and said in a daze: "It's nothing, what did you want to ask just now?" ”

Sima Pingping smiled and said: "I specially observed the layout of this city before, and I found that you ancients are really powerful, whether it is the construction of buildings or roads, they are much more advanced than us, and there are entertainment facilities, which is really enviable." ”

Lei Dazhui showed a smug expression, secretly refreshed that it was natural, after all, he lived in an era of peace, not an era of war.

In the world here, although some technology is far better than in ancient times, there are wars every day, and even survival is a big problem, so how can you have the heart to develop the entertainment industry?

"Although this city has changed beyond recognition, I can still feel its unique charm, so I plan to replan our city construction, maybe it can become a global model city, but there are some places that I don't quite understand, and I want to ask you for advice."

Sima Pingping turned around, pointed to a place on the road not far away, and said: "For example, the lights on that road sometimes flash red, sometimes flash green, and yellow, and also display the reciprocal number, what is the use of this?" ”

Thunder Sledgehammer followed what he was looking at, and suddenly saw the lamp hanging diagonally on the pillar, and couldn't help but be stunned.

I was surprised that the thing was still powered.

"That's a traffic light, referred to as a traffic light, which generally consists of a red light, a green light, and a yellow light, with a red light indicating no traffic, a green light indicating permission to pass, and a yellow light indicating a warning. It's a great thing, and it's a milestone in the development of human transportation, allowing traffic to be effectively controlled. ”

Sima Pingping pondered for a while, and said with some doubts: "Since it is composed of three kinds of lights, why is it only called a traffic light, instead of a red and yellow light?" ”

yes, why are it only called traffic lights?

Lei Dazhui himself was stunned, after living for so many years, he had never thought about such a problem.

He thought about it, and suddenly wanted to hit himself, and he felt like he was being wound in, do I need to think about this kind of problem?

So he said casually: "Because it's smooth!" ”

"Oh, so why is it red, green, and yellow? Is there anything special about it? ”

Lei Dazhui was stunned again, what is this asking? I just move bricks myself, how do you understand this?

At this time, Bai Licai stood up and said with a smile: "From a scientific point of view, it should be set according to the principle of optics, the wavelength of red light is very long, and it penetrates the air."

It has strong ability and attracts more attention than other signals, so as a no-traffic signal, green is used as a notification signal because the difference between red and green is the largest, and it is easy to distinguish. ”

Secondly, if you want to express heat or intensity, the strongest is red, followed by yellow, and green has a colder and calmer connotation. Therefore, the ancients often used red to represent danger, yellow to represent warning, and green to represent safety. ”

"Oh, I see, the ancients really had great wisdom!" Sima Pingping suddenly realized and admired it very much.

In this regard, Lei Dazhui breathed a sigh of relief, patted the fat man on the shoulder, and said with relief: "Yes, yes, it seems that the nickname I gave you is too correct." ”

At the same time that Bai Li was proud, the city lord asked again: "By the way, I went to the subway to take a look before, the underground is very spacious, the road signs are clear, and there are cars, which is extremely spectacular, is that also your mode of transportation?" ”

Lei Da Hammer nodded: "Yes, the subway is much more powerful than the means of transportation on the ground, not only fast, punctual and punctual, but also can reduce urban noise, reduce interference, save land, but an important embodiment of social progress." ”

The lord of the city exclaimed: "The ancients are so smart, we must build this subway too, and it must be fast, and it must connect various cities." ”

"I think so, the subway will not only be a means of transportation in the future, but also a means of escape, once we have a large-scale battle with monsters, then ordinary people can safely escape to other cities through the subway, what do you think?"

After hearing these words, everyone raised their hands in agreement.

"The lord of the castle is wise!"

"This is good, it must be built!"

These people suddenly became very united, and seemed to forget about the battle just now, and instantly turned from enemies to allies again.

Lei Da Hammer couldn't help but give a thumbs up, I have to praise it, this method is really good, and it can ensure the safety of the people to a great extent.

The city lord waved his hand, signaled everyone to be quiet, and then said with a smile: "Since everyone has no opinion, then I will apply to the head after I go back, but in the future construction, I may have to trouble the Great Demon King to help, after all, we only have a general concept of the subway." ”

"No problem, as long as I can help, I can't do it!"

"Then it's settled."

At this moment, the heavens and the earth suddenly trembled, and cracks appeared in the surrounding space.

"What's going on?"

The crowd was shocked.

"Do you want to give birth to a baby again?"

City Lord Sima Pingping's face was a little heavy, and then said: "No, it's that the space is going to be broken, it should be that the energy impact just now is too great, causing the ruins to be closed." ”

"No, so fast, we haven't grabbed a single baby..."

Many people are disappointed, but they don't care about Sledgehammer, they are the biggest winners anyway.

However, he still felt a little emotional, after all, this space belonged to the world of his hometown.

After a flash of light, everything was gone, and they returned to the real world.

I saw the building that had been knocked down, and then you looked at me, and I looked at you, and they were lost in each other, and finally they left.

"Let's go too, let's go home." Ray Sledgehammer said.

Bai Li nodded and released the "Big Mac", and the city lord who was about to leave immediately stopped when he saw the big flying car.

It wasn't the car itself that attracted him, but it seemed familiar, but he couldn't remember it for a while.

I had to ask: "You flying car, I look familiar, have we seen it before?" ”

Hearing this, Lei Da Hammer was stunned, and suddenly had an ominous premonition.

Bai Licai smiled and said, "How is it possible? This flying car was successfully transformed by me yesterday, and it is the first time I have come out today. ”

"That's right."

The lord of the city was a little reluctant, so he came closer, observed carefully, and the more he looked at it, the more familiar it became.

Immediately after, a flash of light flashed in his mind, and a picture appeared in his mind.

At that time, he was crouching on top of a mountain.

With a "whoosh", suddenly a missile exploded.
