Chapter 9

Four kilometers is not long.

After half an hour or so, Yu came to the gate of the city.

After arriving at the city gate, he didn't rush into the city, but walked slowly along the muddy yellow city wall and made a small circle outside the city.

The miniature military camera on the collar clearly recorded the appearance of the city wall.

With the help of the directional signal transmitter and the transfer of the high-frequency base station outside the city, the picture was transmitted to the firewood camp 18 kilometers away in real time.

In the headquarters of the "firewood" team.

A group of newly arrived experts and scholars are constantly analyzing and discussing the useful information in the picture around a 56 inch LED screen.

Although the previous UAV has also photographed the outer edge of the city wall, it is a top-down aerial view after all.

Even if the shooting accuracy of military UAV is higher and the focal length can be closer, it still can't match the quality of face-to-face shooting.

In the picture transmitted back, some details that can not be displayed by UAV are clearly revealed at the moment.

For example, foreign languages that have been pending can now be determined to be completely different from the earth language family.

In addition, the firewood camp also has a more detailed understanding of the height and appearance of human beings in different worlds.

Coincidentally, these alien humans are similar to the Chinese in appearance. They have black hair and black pupils, and their faces are more graceful. They are not as three-dimensional as Westerners.

However, compared with the Chinese, the alien's body is slightly shorter, but the extreme individual is very high - in the picture sent back, people found a strong man about 2.4 meters tall, which even has the opportunity to compete for the Guinness Book of records on earth.

When Yu Lian finished shooting the city wall.

A middle-aged scholar with glasses suddenly frowned and looked puzzled: "no... the height of the city wall was about 15 meters, which was higher than that of Jinling in the Ming Dynasty. This height was abnormal. At that time, the city wall of Chang'an in the Tang Dynasty was only more than six meters.

Normally, the walls of a city of this size are generally seven meters high. "

Lin Li asked, "is it because their basic productivity level is relatively high? There are more human and material resources to build the city wall?"

The middle-aged scholar shook his head and said:

"Team Lin, did you notice the picture taken by platoon leader Yu at the gate of the city?

A considerable part of the travelling people wore patched clothes, and their faces and bodies were obviously malnourished. Refugees even accounted for half of the people entering the city.

Whether the upper class has extraordinary power or not, at least the basic productivity of this city can not be surplus enough to build such walls at will. "

Seeing Lin Li's doubts, another older scholar added:

"In the social morphology, the minimum standard of surplus of basic productivity is the emergence of a large number of middle peasants - this truth is not difficult to understand. Only when people have enough to eat and wear, will they have the heart to squander surplus productivity.

In other words, if the city wall is so high, it must be useful. Let me put forward my opinion... Is it used to defend foreign enemies? "

"Mr. Qian, I agree with you," the middle-aged scholar held his glasses and pointed to the screen. "You can see here... Yes, here it is."

The picture referred to by the middle-aged scholar is located a few meters above the entrance of the city gate, where there is a significant red mark: "can it be blood?"

Then he pointed out several places:

"There... Here... And here, the colors of the above positions are different. Combined with the marks of suspected blood, is it possible that these... Are the traces left by the city wall after the battle damage?"

After hearing the judgment of the middle-aged scholar, the people were silent.

Lin Li felt his chin.

If it is true, as the scholar said.

A city can choose the latter between people's livelihood and urban defense.

Well, I'm afraid the world is not very peaceful

.............

The other side.

After collecting enough wall information, Yu Lian returned to the gate and lined up behind the crowd.

Perhaps because there were too many refugees, the soldiers guarding the city just made a rough inspection and put them into the city.

"Oh, the first level has passed."

After entering the city, Yu Lian quickly approached the corner.

Seeing no one around, he took the opportunity of tidying up his headscarf and touched the headset with his fingers: "Matcha Matcha, this is pudding. I have entered the city and will make the second dessert."

"Pudding pudding, this is Matcha. The first dessert has been received. It tastes excellent. Please continue to make it."

Hang up and breathe out gently.

At the same time, concentrate and recall the urban structure map taken by UAV in your mind.

Soon, Yu Lian located the largest street in the city, and the code marked by the headquarters was the capital letter 'a'.

Then he stooped up and walked timidly down the street like an ordinary refugee.

This urban trunk road code named 'a' is about 20 meters wide and 500 or 600 meters long, crossing the urban center.

The flow of people on the street is barely noticeable. There are all kinds of shops along the street, with all kinds of sounds intertwined. It is the economic center of the whole city.

But in Lian's eyes, what leaps in this street is not human figures, but living and walking Intelligence:

In restaurants and markets, you can collect different kinds of food;

Vehicles passing through the streets can understand the information of foreign transportation tools, which can judge the industrial level of the city to a certain extent.

Some animal powered vehicles can also collect biological information from other worlds - for example, just now, Yu Lian saw a creature that looks like a cow but has six feet dragging a truck through;

Mobile stalls can identify the minimum value of foreign currency. Combined with the trading pictures of some other medium and large stores, with the help of supercomputer, we can find out the monetary system of foreign world;

In addition to the various sounds collected by recording equipment, linguists can at least analyze some foreign common words, and the common words of a language family are often very key basic mother texts.

All these are the benefits of discovering large biological clusters.

As long as we can get into it, intelligence is only a matter of time.

Even if you don't know the language, you can make a hole.

Like the earth.

Who knows if there are scouts from foreign civilizations like Lian in a city who are secretly collecting intelligence?

Cough

get down to business.

The length of street a is only a few hundred meters, which is not long. With the foot strength of this elite scout, you can walk it in a few minutes.

However, in order to ensure sufficient sampling, he often stops and squats outside a shop to collect data without taking a few steps.

Like several shops with good business, Yu squatted for an hour.

Yu Lian is not afraid of being tired. He is worried that he has collected less dialogue data. It is difficult for the headquarters to do sample analysis

So a busy life, the time has passed most of the day.

Along the way, Yu Lian always felt a little uncomfortable - there was something wrong with the atmosphere of this street.

There were a large number of refugees wandering in the street, and the pedestrians on the road looked hurried.

Even in those shops doing business, customers and shopkeepers are absent-minded to complete the transaction.

It looks like something big is going to happen.

When the company was going to visit a street again to see if it could find any clues, a new communication came from the headquarters:

"Pudding pudding, this is Matcha. The second dessert has been tasted. It has rich materials and rich taste. Please start making the third dessert. Repeat, please start making the third dessert."

Yu Lian immediately flashed to the corner. Although he was eager to find out what happened in the city, the soldier took obeying orders as his bounden duty, so he immediately replied: "the pudding received, the pudding received, and now he began to prepare the third dessert. The preparation process may be long. Please wait patiently."

After hanging up the communication, Yu Lian found an intersection at will and left a street quietly.

His next goal is the largest mansion in the city: the eight in and eight out manor in the previous picture taken by UAV.

It is also the most luxurious building in the city - in addition to the manor, the largest courtyard in the whole city is only four into the pattern, with a difference of exactly twice.

If a street is the economic center of the city.

Then what the mansion represents is undoubtedly the power center of the city.

At the same time, it is also the most likely building with extraordinary power.
