It's just that...... Just when we flew for about ten minutes. A thunderous sound came from below, and then I heard a loud explosion, and there seemed to be a flame in front of me! ”

"Everyone was a little panicked...... More thunderous sounds followed, and the screams of my companions began to be remembered around me! At that time, I didn't know where to fly, I just flew as hard as I could in the sky and in one direction! I don't know why, but three days later I found myself flying out of that 'foggy' area and back to the capital country......"

Liu Ye didn't speak, and seemed to be lost in thought......

After a few minutes, he looked up, and with a determined look in his eyes, he said, as if he had made up his mind:

"All the troops are assembled at once, and they are assembled along the northern route! At the same time, the Supreme Realm Order was issued, and all citizens were arranged in accordance with wartime regulations! ”

"Yes!"

The words of the Eagle Bat team members had already understood something to the rest of the meeting, so Liu Ye's words were passed on without hindrance.

Liu Ye took the helicopter equipped with the "door" and "door" of the air finger department, and quickly felt the Beiping fortress.

"Liu Ye, it seems that you guessed right this time! The six northern countries finally couldn't help but do it! Then it can also be determined that those who attacked New Maya City and the behind-the-scenes commanders of the Six Northern Kingdoms should be the same force! ”

After Qianba stopped Liu Ye's words, he came to such a conclusion,

"Now that the identity of the opponent can be determined, I think we still underestimated the opponent before!"

"You're right! If you want to shoot down planes and eagle bats from an altitude of 10,000 meters, with the military strength of our capital, it is nothing! But if such military strength is put in front of an upcoming adversary, it is not so optimistic! Qianba nodded.

"I've now begun to think about whether the defense of the Beiping Fortress is a little thin! Although the fortress is strong, it will not be able to survive the tilt of more firepower! Liu Ye sighed and said.

"If the production of special cement can break through the limit, then the defensive 'nature' of the fortress is no longer a problem!" Qianba also sighed and said.

Due to the production restrictions of special cement, the buildings of the fortress in New Peiping are not all made of special cement, but are coated with special cement on the outside, and the inside is built with first-class cement.

Although this speeds up the construction period, the defense only reaches the general defense level of special cement. If the attackers had very strong firepower, then it would be possible to break through the walls of the northern fortresses.

"I understand! However, at present, the production of special cement is limited by both technology and materials, and the stalk has been improved as much as possible! Liu Ye shook his head helplessly, he also hoped that special cement could be produced normally, but everything could not be as good as people.

"Now there's only one thing we have to do, figure out what that damn 'fog' is right now, and figure out how to dispel it!" Liu Ye said categorically.

With the accounts of the returning Eagle Bat soldiers, the Air Finger Division's 'Gate' immediately sent a second batch of air force troops.

With the experience of the first time, the second group did not enter the 'fog' area, but conducted sampling and research in front of the 'fog' area, and then immediately returned home.

The samples obtained were sent to the stalk for study, and the results were finally obtained under the strong scientific research ability of the scientific research department.

"These 'fog' fogs contain a strange kind of particles, which appear to be an organic substance, capable of absorbing all kinds of electron 'wave' lengths and visible light 'wave' bands in them! Moreover, these 'fog' fogs seem to have a kind of growth 'nature' of their own, which can slowly spread to the range, so it is recommended to expel them as soon as possible! ”

"What kind of weird thing is this that can grow on its own?"

Looking at the thin page in his hand, Liu Ye knew that this was the result of their hard work day and night.

"I see! No wonder communication is cut off and you can't see! Liu Ye said secretly in his heart.

"Given that this particle is made up of organic matter, it is advisable to use biocidal means to dispel these 'fogs'! Here's how......"

Not only did they find out what these 'fog' were, but they also found a way to get rid of them.

Now that he had a method, Liu Ye immediately ordered his subordinates to try.

Three days later, twenty large transport planes loaded with repellents flew to the northern 'foggy' area. These planes do not need to enter the 'foggy' zone, but can fly overhead.

As soon as they reached the northern 'foggy' area, the twenty large transport planes immediately opened the hatch in the tail. A substance like a pesticide 'medicine' spray poured out from the plane, and as these sprays were sprinkled, the 'fog' below seemed to melt like rain and snow, and disappeared one after another.

Twenty planes sprayed back and forth, and most of the day passed, and the air below returned to its previous clarity.

However, the restoration of the clear air made Liu Ye and them gasp.

Dense black dots like a swarm of black 'colored' ants covered the entire ground and swarmed in.

As can be seen from the photos taken by the camera attached to the transport plane, these black dots are all people. They were all armed and followed by a small number of motorized troops.

"According to estimates, the number of offenders this time should be more than 100,000!" An encrypted telegram was quickly delivered to Liu Ye.

"One hundred thousand?" Liu Ye looked at the telegram in his hand and read the words.

"It's still here! Finally can't take it anymore? Liu Ye's eyes looked into the distance, and they seemed to be shining with scorching light.

Soon, more detailed photos were taken.

From the 50-fold magnification of the photo from the on-board camera, it is already possible to clearly distinguish the appearance of the other party.

Obviously, they are also human. However, it is clear from their appearance that they are not Asian.

The high forehead, sunken eye sockets, broad shoulders and tall stature, as well as the full head of blonde hair and blue 'color' eyes, all indicate that they belong to the Nordic race.

These people's clothing is quite 'messy', and there is no uniform dress code at all. The function is only to keep warm.

Their faces were full of exhaustion and hunger, and they staggered as they walked.

At first glance, these people seemed to be a group of refugees who had fled and were running towards the capital.
