Tens of thousands of meters high.

In thin atmospheric environment.

The Fire No. 1 plane flew south at a speed of three times the speed of sound.

Passing through countless green mountains and waters, passing by countless kingdoms and cities, two days and two nights later.

In the early morning of the third day, the Flying Altitude of Fire No. 1, whose speed dropped to subsonic speed, was reduced to less than 10,000 meters.

Zhou Ming and others entered the territory of the Witros Empire.

The Witros Empire is one of the most powerful empires in the human world.

The empire's territory is vast, with an area of ​​at least fifty times that of the Kingdom of Atud and twice that of the Doran Empire... The territory covers more than 30 million square kilometers.

Due to the flat and fertile land, dense rivers and abundant resources, the country has a large population... about 5 billion.

In other words, the population density of the empire reached 166.6 people per square kilometer.

This is a pretty amazing number.

The Z country in the real world where Zhou Ming is located has an average population density of only 130 or 40 people.

I'm afraid some people would say they don't believe it. In such a world with low productivity and average technological development, how could a feudal empire have a population density that is higher than that of the Z country in the real world?

However, according to Zhou Ming's naked eye observation, through the density of the village towns below, as well as the number of farmlands and systematic calculations, the Witros Empire is indeed a human country with extremely high population density.

The systematic explanation is: "Most of the territory of the Vetros Empire is fertile plains, which can be developed into large areas of farmland. In addition, the weather is good, the hydraulic irrigation facilities are perfect, and the output in the land is feeding so much of the population, and there is no big problem."

"In addition, the possible outbreak of plague caused by high population density is almost unlikely to occur due to the existence of the Holy See."

"Even the [healing agent] prepared by pharmacists can kill 99% of harmful bacteria."

"What's more, the technological level of the Wittros Empire is not that behind."

Zhou Ming nodded.

The system is right. The level of scientific and technological development of this empire is indeed not that backward. It can be said that it is equivalent to the earth after the first industrial revolution.

Because Zhou Ming saw dense railway lines.

I saw the steam engine factory with rolling black smoke coming out.

Even around some large cities, a large number of telephone poles and transmission towers were seen... orange street lights can be seen at night.

Zhou Ming was really surprised now.

He said secretly: Is this empire developing in the direction of the Second Industrial Revolution?

This level of development is probably decades ahead of the Adude Kingdom, which is entering a capitalist society?

In addition, Zhou Ming also saw some special buildings that surpassed conventional technology... the Mage Tower standing on the plain with a height of more than hundreds of meters.

These mage towers are complex and powerful, and can even adjust the climate around the mage tower by operating magic elements ranging from thousands of miles apart.

For example, if a drought occurs, the Mage Tower can release large rainfall spells to allow crops to harvest.

If a flood occurs, the Mage Tower can release large wind-type magic to blow away cumulonimbus clouds in the atmosphere.

There are dozens of such advanced mage towers in the Witros Empire.

In short, it would be strange if the Wittros Empire was not very large in its population.

As for why the level of technological development is so high, the system also explains: "This should be caused by the technological spillover of Magic City. The level of technological development of Magic City is definitely much higher than here."

Zhou Ming nodded.

Someone may ask questions here: Since even the technological products such as railways, steam engines, power grids and other technological products have been released within the territory of the Vitros Empire, why was the Kingdom of Adude 300,000 miles away so primitive and backward at the beginning?

Why didn’t any of these technological products be spread to the Kingdom of Adude?

This is actually not difficult to explain at all.

The highly closed feudal era seriously restricted the movement of people and the exchange of technology.

For example, when the real world of Z country introduced the inventions of ancient times, history books often said that papermaking was hundreds of years earlier than the West, compass was hundreds of years earlier than the West, and even a simple ox yoke and curved plow was invented thousands of years earlier than the West.

For example, the decadent and backward braiding has entered the industrial age for hundreds of years, and it is still closed down here. The technological level has not only not improved, but has retreated a lot.

Therefore, for the human world of Azeloa, as long as most kingdoms are still under the rule of the feudal system, even if the development status of science and technology and culture is thousands of miles apart, there will be obvious differences for at least several hundred years.

In addition, countries that master advanced technology are also afraid of "teaching disciples and starving their masters to death", so they will strictly limit the spread of advanced technology.

In short, the existence of multiple factors has led to a relatively unbalanced level of scientific and technological development in various places in this area.

After wandering around the Witros Empire for most of the day.

When the system observed an extremely huge city, Liehuo No. 1 headed straight for the giant city.

Niata City.

A super city built on a raised mound.

That is the imperial capital of the Witros Empire.

How huge is this city?

It covers an area of ​​more than 50,000 square kilometers.

The number of buildings of various types exceeds one million.

The total population is estimated to be around 50 million.

But the population of this city is more than that of the entire Kingdom of Atud!

Zhou Ming, who has seen many big scenes in front of a city of this size, may think it is nothing.

But Teacher Sails and student Henry, who were sitting behind, were both dumbfounded.

"It's too big...it's too big!"

"I have never seen so many houses in my life."

Teacher Seles is also a person who has seen the world. He already thinks it is very magnificent and magnificent in the imperial capital of the Doran Empire, but in front of Niata, it is a witch.

Zhou Ming smiled, controlled "Firehuo No. 1", found the branch organization of the Mainland Chamber of Commerce located in the north of the city, and operated the plane and slowly landed.

A small episode also happened in the middle. A griffin patrol patrol in the airspace of Niyata City immediately surrounded him after seeing "Firefire 1", approached the plane and asked Zhou Ming and the others about their identities.

and the purpose of his arrival.

Zhou Ming used magic amplification to express: He was a magician from the Kingdom of Yadu and came to learn and communicate.

The other party nodded slightly. The magic of the Witros Empire was very developed, and there were many magicians who came to communicate and learn every year.

But...for the sake of the security of the empire, any mage who comes to the Wittros Empire must hold a letter of recommendation from the senior executives of the Magic Association to carry out free activities, otherwise they must be under 24 hours of surveillance.

Zhou Ming had a letter of recommendation. After the Liehuo No. 1 landed at the Mainland Trade Fair, Zhou Ming took out a letter of recommendation written by Santos, president of the Magic Association of the Yadud Kingdom, from the space ring.

But after reading this recommendation letter, the captain Griffin Knight shook his head: "This letter is useless. It is not written by the elders of the Magic Society. The recommender of this letter is just an ordinary director. He does not recommend you the power to stay in the Witros Empire for a long time."

"So I am very sorry to tell you that you can only stay legally in the Witros Empire for seven days when you are under surveillance. If you have more than seven days, please leave consciously."

What?

Zhou Ming and others were shocked.

Can you stay legally for seven days?

What the hell is the Witros Empire doing? How do they treat them, such foreign guests?

Teacher Sails said even more annoyed: "Do you know what you are talking about? You are expelling the noble magician! You and your empire may have offended three powerful magicians!"

The patrol captain shrugged: "Sorry, this is the legal provision of our empire and any wizard must comply with it, without exception."

"you--"

Sails raised the staff in his hand.

"If force is used, you will be expelled immediately!" the patrol captain said in a tough tone.

The head of the Mainland Chamber of Commerce and Industry on the side hurried forward to smooth things over: "The Witros Empire does have such regulations, which began to exist decades ago. It has not changed by anyone. Mr. Leilin, Mr. Sails, don't be angry, please don't be angry."

"What should we do? Should we stay here for seven days before leaving here?" Henry asked. None of them expected this would happen.

They also plan to go to the legendary Magic City by setting up a teleportation array in the Witros Empire.

The person in charge of the Mainland Chamber of Commerce said that he has a solution.

"What method?" Zhou Ming asked.

"Finding an elder of the Magic Society in Niata City and asking him for help with a letter of recommendation, which may cost a little money and would be better off getting the letter within seven days."

The solution of the person in charge is to find an elder of the Magic Association locally and issue a letter of recommendation.

But the money that needs to be spent cannot be a decimal, it depends on whether an elder of the Magic Association is willing to help this?

In addition, those who can become elders of the Magic Association generally do not lack money and may not have that time.

It is even less likely to be helpful, so I can just write a recommendation letter to a few strangers.

So based on the above situation, it is quite difficult for Zhou Ming and others to stay in the Witros Empire.
