Two months have passed, and the new Beiping City has been miraculously built under the designer's day and night old things.

The labor and material resources consumed in this process were quite large, and for the completion of New Beiping, Liu Ye and they were tired to death of more than 1,000 workers.

Of course, these workers were temporarily conscripted from the jurisdiction of the six northern cities, and they had offended the Dadu State before, so now they should be regarded as compensation for the Dadu State.

"Human potential is truly limitless!" Looking at the magnificent strong fortress in front of him, Liu Ye couldn't help but sigh with emotion.

The timely completion of the New Beiping Fortress also made Liu Ye a little relieved, and he was able to grasp a little bit about what would happen in the future.

As for the tired laborers, Liu Ye adopted an attitude of ignoring them.

Liu Ye is not a Bodhisattva Buddha, and it is impossible for him to let go of those who dare to violate him with compassion.

In this wasteland, a savior is needed, but so are cold-blooded executioners.

Liu Ye doesn't mind making a cameo at the right moment, the latter's role 'color'.

For the six northern countries, Liu Ye also did not dare to take it lightly. But when he sent the Eagle Bat Army and some of the air force mechanized units to reconnoitre, he saw a land shrouded in thick fog.

The terrain of the wasteland has changed dramatically compared to before the war. The use of high-yield bombs and seismic tactics not only brought unexpected damage to the enemy, but also caused a dramatic change in the terrain.

Moreover, the application of these methods of warfare awakened the lava river belts and extinct volcanoes that had been sleeping underground, and after some eruptions and cooling, new mountains were formed.

Over the course of a hundred years, these new mountains have become unfamiliar plots on the map.

At first glance, it seems that these thick fogs may be some kind of environmental reaction brought about by the closure of the 'jade' belt system.

But Liu Ye always had a sense of déjà vu with these fogs, as if he had seen them somewhere.

"Give me more detailed photos! I need to see what the fog is covering! Liu Ye asked for the 'door' of the empty finger department.

Liu Ye's order was well carried out, and in order to find out the source of the fog, 15 newly developed unmanned reconnaissance planes flew toward a fenced area in the north, accompanied by a group of eagle bats.

However, the actions of the 'gate' of the Air Finger Department received unexpected results, and after the 15 unmanned reconnaissance planes were dispatched on the same day, they never returned.

In some respects, the aviation technology that the capital country currently has in possession is probably far inferior to that of similar aircraft before the war. But in any case, a machine that can fly into the sky is quite powerful in itself.

What's more, this is the first human-made aircraft that appeared after the extinction of human beings.

Fifteen thousand meters of these fifteen unmanned reconnaissance planes is already their highest limit, and at such an altitude, they can avoid most biological attacks.

Even the Eagle Bat Army's current limit altitude is only at an altitude of 10,000 meters, which is still much worse than that of unmanned reconnaissance aircraft.

However, this is how the high-performance aircraft compared to the wasteland has disappeared inexplicably.

According to the return of the 'gate' of the empty finger, it seems that the fog has the ability to shield the electric 'waves'. Since the unmanned reconnaissance aircraft entered it, they have not received a single telegram back.

As for the Eagle Bat Army, there is no news.

For such a result, the empty finger department 'door' is puzzled. They really couldn't think of anything that could hurt the Air Force Department's 'gate', which was flying at an altitude of 10,000 meters.

Even if it is a group of tribes with innate divine powers, they can throw the spear in their hand to a thousand meters at most, and after a thousand meters, the spear is already at the end of the crossbow, and it is difficult to cause damage.

The only possibility that the 'door' of the air finger department thought of was that the plane had malfunctioned due to the change in the environment, so there was no news. But if that's the case, the Eagle Bat Army should also give back.

Originally, the purpose of sending the Eagle Bat Force was to prevent problems with the unmanned reconnaissance planes so that they could take over their duties.

Everyone is speculating, and everyone thinks differently.

Three days later, in the early hours of the morning, an order from the 'door' of the Empty Finger Department solved all the mysteries.

Immediately after that, the supreme authority also issued a wartime mobilization order to the citizens of the capital, requiring everyone to be ready to fight at any time.

The whole country was in an uproar, and at this time, Liu Ye and the others were nervously holding a secret meeting at the 'door' of the empty finger department.

"You say you're being attacked?" Liu Ye's tone was suspicious.

The person questioned by Liu Ye was a middle-aged man who was full of exhaustion and had a mixture of blood and sweat.

From his tattered clothes, it can be vaguely seen that this person should belong to the Eagle Bat Army, and it is the Eagle Bat Army member who entered the northern 'misty' fog area some time ago to carry out reconnaissance orders.

"Yes! As soon as we entered the 'fog' zone, we lost contact with each other, and that damn 'fog' seemed to block all electrical 'waves'! The middle-aged man said tiredly.

The rest of the participants were silent, and the middle-aged man's statement was the same as they expected, that the 'fog' fog really had the effect of blocking the electric 'waves'.

"You can't see each other?" Liu Ye felt strange in his heart and asked.

You must know that even if there is no wireless connection, the eyesight of these eagle bats is enough to see the location of the surrounding team members.

"Invisible! From a distance, the fog looked like a thin layer, but as soon as you entered it, you found that it was all around you with a dense mist, and you couldn't see anything but yourself! The middle-aged man recounted.

"Tell me about your attack!" Liu Ye asked after thinking for a while.

The middle-aged man's eyes showed a terrifying look, and he took a deep breath before saying, "Because I lost contact with everyone, I can only fly according to the route I used to train. Fortunately, everyone thinks the same way as me, and although I can't see everyone, the sound of air currents in the air lets me know that everyone hasn't dispersed yet! ”

Liu Ye and the others nodded secretly, although their vision was blocked, but their sense of hearing and smell could also play a similar role.
