The correct way to open the sprite

Telephones are necessary. Cattail City should basically be on the defensive in future wars. The connection and information transmission between various units and fortresses are extremely important. The key is that the telephones are wired, so there is no need to worry about interference.

When talking about telephones, we have to mention one thing, a switch.

The earliest telephone switches were people, relying on manpower to find the required interfaces and manually connect the call lines.

As for the development of switches, the process of switching from manual to machine, there is a little story that has to be told.

In the era of manual switches, a funeral home owner named St. Joe discovered that calls that were supposed to go to his store were always routed by the operator to another funeral home.

Later, after investigation, Shi Duanqiao found out that the local operator was the cousin of the owner of another funeral home.

He was very angry, but he had no choice, because very few people who called the funeral home even named which funeral home to contact. After all, no one had time to pay attention to this kind of company, just call the funeral home.

And the operator didn't do anything wrong. The caller only asked to be connected to the funeral home, but he didn't ask which funeral home to be connected, so he could connect to any one. This was allowed in his job, unless the customer Limited to a certain funeral home.

Stuanqiao was very angry about this, but instead of going to trouble the operator, he decided to invent a switch that did not require manual operation, put the operator out of work, and solved the problem from the root.

As a result, Strangchio really did it. He made the world's first mechanically controlled switch in his garage and invented the rotary dial telephone that is very common in film and television works.

By rotating the dial and dialing numbers one by one, the lines of the switch are controlled to change position little by little, and finally connected to the telephone line that needs to be connected. This is the working principle of this kind of switch.

As we can see from this true story, Uncle Sam's garage has been magical since this incident happened one year ago.

Also, don’t think that the telephone exchange is too magical. In fact, this thing was invented by a funeral parlor owner named Stuanqiao in one year.

As for the subsequent development of telephone exchanges more and more rapidly, it is because the number of telephones on the earth is increasing.

What Cattail City needs to solve now is whether there are any problems.

Fortunately, the mechanical-fan dwarfs of the Scientific Research Institute collaborated with electromagnetic researchers to easily create this inefficient switch, allowing Cattail City to move beyond the manual plug-in call method and enter the era of dial-up calls.

In the field of telephony, Cattail City had a sort of catapult start.

Feng Yu was very satisfied with this. As for automated switches such as semiconductors, he hadn't dared to think about that.

He was chatting with a beautiful elf girl at the moment. Miraculously, Nicole was still watching.

Don't think wrongly, this elf lady is the elf singer that Nicole found for Feng Yu, and she came here to audition.

The appearance of microphones and speakers reminded Feng Yu of a classic scene, Shanghai at night.

"Cattail City, Cattail City, you are the city that never sleeps."

Thinking of this, Feng Yu thought of cheongsam again, and then thought of cheongsam Luo Tianyi, and then his thoughts and saliva went crazy.

Looking at his long-legged elf cabbage Nicole, Feng Yu silently wrote this down in his little notebook.

It was only now that he suddenly realized that what he lacked most was not an auditioner, nor a telephone or telegraph, but a tailor with superb skills who could turn the styles in his memory into reality.

As a senior single and promising young man, Feng Yujue has the responsibility and obligation to let the earth's culture be presented one by one in Green, such as clothing and special clothing.

It would be a huge failure if we simply brought the element of war to Gerien.

Frying and stir-frying has taken root here, but will basic necessities, food, housing and transportation be far behind? Will house culture be far behind? Will moon-making be far behind?

What Feng Yu didn't know was that while he was still thinking about it here, a discussion about him was also going on high in the sky. The two parties involved in the discussion were the golden dragon Paul Jin and the wind magic Saint Cromwell.

The giant dragons claim to be the guardians of Gray's plane. It is their mission to monitor and eliminate creatures from other planes. As for Feng Yu, anyone with some knowledge can guess from various signs that he is basically They are not indigenous creatures of the Gerien continent.

Paulkin believes that unstable factors like Feng Yu are likely to bring unpredictable changes to future plane wars.

In other words, Paulkin believes that Feng Yu’s existence should be eliminated.

This is not to blame the golden dragon Paul. In terms of strength, Feng Yu defeated his child Clark. A round of long-range attacks, large-caliber magic-breaking bullets, and even ordinary bullets fired by demon-hunting and anti-aircraft guns can threaten the dragon. .

You know, those who operate those weapons are not great magisters or magic saints. If those weapons require high-level magic units to operate, the dragons are not worried. After all, there are only so many high-level magic units in Pancontinent.

But the bad thing is that those who operate those weapons are a group of ordinary people, ordinary people without any magical power, and those weapons can be manufactured on a large scale.

Now, these weapons have even spread to the hands of the four minority races, and the safety of the Dragon Clan cannot even be guaranteed in these areas. How can this not make Paul, an elder of the Dragon Clan, afraid of Feng Yu.

But now humans have a Dharma Saint, and there is no doubt that the Dharma Saint is the leader of the plane war and the pinnacle of Gray's personal power.

Although he is said to be on an equal footing with the great elder of the Dragon Clan, the Dragon Clan himself also knows that the previous Elf Saints do not really think highly of the Dragon Clan.

It can even be said that the previous Dharma Saints of Gerien do not think highly of the Dragon Clan, which can increase its strength by relying on talent to eat and sleep, but has never produced a saint-level powerhouse.

It’s not anyone else’s fault. Many giant dragons still eat their hair and drink their blood. Moreover, giant dragons don’t like to use their brains. They know that they destroy but don’t know how to build.If it were not for the innate inheritance of knowledge, they might not even have their own language.

The Cromwell Master seemed to have an ambiguous attitude towards Feng Yu, who had defeated humans twice. The defense of Cattail City and Feng Yu's combat effectiveness also made Paul give up his attempt to forcibly eliminate Feng Yu.

He still remembers Feng Yu's ruthlessness in fighting, his no-nonsense, no-holds-barred, deadly fighting style, and the weapons he carries with him, all of which are still fresh in Paul's memory.

He was a fifth-level golden dragon, but after fighting Feng Yu, he even experienced the threat of death more than once.
