When she was sighing, the girl at the front desk said: "Dear guests, there is a gladiatorial arena in our city, and these monsters will be sent to the gladiatorial arena, and then become the pleasure of the noble lords. ”

"The Colosseum?" Song Ziyu was a little surprised.

The girl at the front desk said excitedly: "Calculate the time, that is, tomorrow night, Sweetwater Town will have a high-standard gladiatorial competition, and at that time, each side will send its own representative team to fight in the gladiatorial arena...... That's a special pleasure in our city. ”

"It was only at that time that ordinary people could enter the city and enjoy a pleasant life."

"Is it so exciting? It seems that I need to feel the local customs. Song Ziyu said.

Hearing Song Ziyu's words, the little girl at the front desk suddenly walked up to Song Ziyu, reached out and touched Song Ziyu's private parts, and then said in an almost provocative tone: "This gentleman, if you are willing to pay a sum of money, I can provide you with additional services...... Let you experience the unique customs and customs of Sweetwater...... Best of all, you don't have to take any responsibility afterwards. ”

As she spoke, the girl squeezed her career line to make herself as material as possible.

"Thanks, I don't need to." Song Ziyu remembered that in the half-hidden roller shutter doors that he passed by in the civilized world, there were always young ladies who scratched their heads and called "handsome guy, come and play".

This made Song Ziyu couldn't help but run away.

……

The following time, Song Ziyu left the hotel and traveled to various parts of the city.

After some wandering, Song Ziyu reassessed the level of civilization in Sweetwater Town.

The level of industry in this town has reached the level of the average town in the civilized world.

Here, you can see many industrial products for yourself.

For example, there are fired glassware, various mechanical parts, etc., and there are even various large mechanical vehicles for sale.

But in general the quantity is scarce, and the quality is not flattering.

But there is one thing that Song Ziyu is very curious about, that is, there are five rings and twelve boundaries in Sweetwater Town, and there is electricity supply within the third ring!

My Healing Game

What does this prove?

Proof that the city has a systematic power supply.

This aroused Song Ziyu's desire to explore.

Following the complicated wires, Song Ziyu stopped and found a small thermal power plant.

The shape of this power plant is magical!

Towering steel towers, mountains of coal, towering furnaces, and grid-mounted towers around the city's northeast, south, and northwest corners all have a steampunk feel.

Blade Runner, this is.

After Song Ziyu admired it, he quickly fell into deep thought.

Looking at it from the perspective of a little bit of electrician knowledge, Song Ziyu found that the power grid built around the power plant was somewhat inexplicable.

The structure of this grid domain field is actually the use of direct current!

Song Ziyu read through the history of the world and knew that when mankind had just mastered electricity, there was a collision between using alternating current or direct current as the mainstream electric drive.

After a long tug, capital chose to succumb to reality. Eventually, alternating current replaced direct current and became the mainstream of the market.

But at present, this situation of building an electric tower every 500 meters for energy conversion is really blinding, and it completely subverts Song Ziyu's cognition of the power field of industrial civilization.

"The person who built this power grid must be a psychopath." Song Ziyu couldn't help muttering to himself.

"Who do you say is a psychopath?" An old voice suddenly came from behind him, and it looked a little unkind.

Song Ziyu looked back, but saw an old man in old gray overalls, blowing his beard and staring at him.

Song Ziyu pointed to the power grid and explained to the old man: "This is the connection method of direct current, the energy utilization rate is very low, the power cannot be returned, the power generation can not go up, and the energy escape will be very serious...... So I had to build a tower every few hundred meters to complete the energy conversion! In this way, the cost of power storage and transmission is very high. ”

To be honest, Song Ziyu's expertise in electricity is only half-baked, but this half-trick is enough to frighten the old man.

Really!

Hearing Song Ziyu's words, the old man put away his aggressive expression, and then fell into deep thought.

"Then how do you say this problem will be solved?" The old man asked.

"With alternating current!" Song Ziyu said as a matter of course.

"What is alternating current?" The old man asked.

"Alternating current refers to the current whose direction changes periodically over time, with an average current of zero in a cycle. Unlike direct current, which changes its direction over time, direct current does not change periodically. Song Ziyu moved out of the high school physics Dafa, a series of professional terms, and the old man was stunned.

The old man didn't know who it was, but his eyes were getting brighter and brighter.

On the other hand, Song Ziyu, the ink in her stomach has been spilled, and if she continues, she will be exposed.

So Song Ziyu snorted and said: "Oh, the problem of electricity is very complicated, and I can't tell you in a few words, that's it, goodbye." ”

After speaking, Song Ziyu was about to yo-yo.

"Young man, stop me!" The old man grabbed Song Ziyu's hand, and then said, "Boy, I see that you are very pleasing to the eye, go to my house to talk?" ”

"Who are you?" Song Ziyu frowned and asked.

"Me?" The old man smiled incomprehensibly and said, "No, this power grid was designed by the old man." ”

Song Ziyu was a little dumbfounded!

As the saying goes, you don't slap people in the face, and what I said just now obviously didn't save face for the old man.

"I'm sorry, old man, I didn't mean to offend...... So be it! Song Ziyu turned around and slipped away.

"Boy, you come back to Lao Tzu!" The old man shouted.

But Song Ziyu didn't pay attention to it at all, and his feet were faster.

"Alas, I'm mad at me!" The old man chased a few steps and couldn't keep up, so he could only beat his chest.

"Boy, I'll wait for you here tomorrow, if you don't come, you'll regret it!" The old man yelled at Song Ziyu.

Song Ziyu, who walked away, didn't care, this old man had a big temper, and he wanted to eat himself.

"What a strange guy!" Song Ziyu muttered to himself.

……

After leaving the power station, the old man turned around and walked towards the inner city core.

After passing through several levels in a row, the old man entered the first ring of the realm.

Located on the oasis wetland, it is the best location in Sweetwater Town, and the people who can live here are either rich or expensive, and all of them are prominent in Sweetwater Town.

The old man walked leisurely as if he was walking, and the security personnel of the elite area showed respectful expressions when they saw the old man.

The old man ignored the murderous fellows and walked straight into a manor

"Sir, you're back." The servant said respectfully.

"Well, is Wu'er back?" The old man asked.

"Report to the eldest master, the eldest young master hasn't come back yet." The butler spoke.

"Let him come back to my study." The old man confessed and returned to his study.
