"According to the topography, the city wall should be built on the plateau in country Z, what is the purpose of such a huge project? Expanding your territory? Or defend against zombies or other dangerous creatures? Countless thoughts flashed through Han Dao's mind.

The sudden attack of the end times swept the whole world almost instantly, and the governments and armies of all countries were devastated.

As a neighbor of country Z, Han Dao clearly remembers that the three countries of A-Sanguo are one of the most populous countries in the world, and relatively speaking, the sudden outbreak of zombies will also be extremely terrifying.

Even if there are some relatively powerful survivor gatherings in the country like Z now, it should be in a defensive state, and how can it appear in large numbers on the territory of other countries.

If it is before the end of the world, the territory may still have its meaning, but in the last days, too large a territory means that huge fortifications need to be built, and more combat power is needed for daily patrols and defenses.

In addition, the land on the plateau is barren and lacks mineral resources, as long as it is a normal gathering place, it will not risk extinction to occupy this barren land.

"The only possibility...... It's just that there is some kind of scarce resource nearby, and it is a resource of great value, and it is worth a large gathering place to risk its destruction to obtain this resource! and the construction of the city walls...... It's to guard these resources!" As he continued to analyze, Han Dao's eyes suddenly flashed.

The mysterious map found on the two men before and the mysterious behavior of Ah Sanguo were enough to confirm his suspicions.

"Commander, there's something unusual coming back from the reconnaissance team!"

The voice of Zhi Brain suddenly sounded, and in the virtual screen, it can be seen that a magnificent glacial mountain range is located below the two century bombers, and the mountains are endless, among which there are many towering peaks.

"Himalayas!" Han Dao frowned slightly, as a world-famous mountain range, Han Dao recognized it at a glance.

This mountain range covers a huge area, and the two century bombers began to climb continuously, and as the altitude of the planes increased, the picture on the ground gradually became comprehensive, and Han Dao was surprised to find that the city wall built by the Three Kingdoms of Afghanistan was actually closely surrounded by several peaks on the border line.

"These peaks ......"

The picture on the screen zoomed in quickly, and soon it was locked on one of the peaks, and at a glance, Han Dao could see that something was wrong, there was a black hole area of tens of square meters in size on the mountainside of this mountain.

It is not an ordinary cave, but a real black hole, like a deep cosmic space, in which there is no trace of light, but it calmly exists on the mountainside, and the waves are not alarming, and it looks mysterious and abnormal.

"Warning! Warn! Highly civilized residual information detected!"

"Highly civilized?"

"Civilizations above level 4 are called high-level civilizations!" Zhi Brain explained.

"Level 4 or higher?" Han Dao was still a little confused, Zhi Brain had never mentioned these words before.

"What level of civilization is the current civilization on Earth?"

"The earth's technology is currently in the stage of orbiting the planet, and it belongs to the seventh-level civilization!"

"Shhh

Han Dao instantly gasped when he heard this, and his first thought was to immediately stop Ah Sanguo from further studying the black hole region. The current level of civilization on the earth can only be regarded as a seventh-level civilization, and one can imagine how terrifying the civilization above the fourth level is.

Such a power, once it is acquired by others, not to mention that with the current strength of country Z, I am afraid that it will be its own red police base, and it will not be able to compete with the other party. At that time, the entire country Z will be reduced to the other party's subordination, and the survivors of country Z, including themselves, will not end well.

"Wisdom Brain, a civilization above level 4, is just residual information, if it is obtained by other forces, how long will it be used in reality in the shortest?"

"With the current level of science and technology on the earth, it is unlikely that the residual information of the fourth-level civilization or above will be forcibly analyzed, but if it is some branch civilization, such as the information of the fifth-level civilization, it will be successfully analyzed in a month, and it can be used in reality within six months!"

Zhi Brain's explanation made Han Dao's heart chuckle violently, the city wall project built over there was almost complete, such a huge project, even in modern times, could not be completed in a few months.

In other words, it has been at least a few months since the discovery of the black hole region in the three countries, and it is difficult to be sure whether the other party has gained anything from it.

"Brain Intelligence, with the current strength of the base, can it destroy the black hole area?" Regardless of whether the other party got anything or not, Han Dao's only thought now was to completely destroy this time bomb that would explode at any time.

"The difference in technology is too big to destroy!"

"Order: A hundred spies from the God of War base, with the Century Bomber, must maneuver to the target location within three hours, and within one day, all infiltrate the enemy!"

"Yes! Commander!"

Hundreds of kilometers away, on the outskirts of the God of War base, in a certain military base, a large number of capable men in suits ran out of the barracks in a line, quickly gathered together, and in the camp, three century bombers were already waiting here.

Han Dao's order was directly issued to each soldier by Zhi Brain, and in just a few minutes, a hundred spies had already completed boarding, and three Century bombers roared into the sky, and soon disappeared into the sky.

…………

The Northwest Order Sub-Bureau is stationed

Outside the towering Wisdom Tree, thousands of rattans sway in the wind, and you can see employees holding folders constantly walking in various sections of the Wisdom Tree, and the entire sub-bureau is orderly, peaceful and quiet.

No one knew that at the top of the Wisdom Tree, several terrifying consciousnesses were intertwined, stirring up strong consciousness fluctuations from time to time.

"The first-class group of the first department was all damaged in battle, that place, the old man had already said that with the strength of these people below, it was impossible to explore at all! So far...... If something goes wrong...... How can we explain it to the above? ”

"The first section of the first-class team is already the strongest force we can dispatch, since it has been damaged in battle, I think it should be reported to the director immediately, and his old man will decide!"

"Humph! Everyone knows that the director is asleep and wakes up rashly, if he is unhappy, who will bear the consequences? ”

"So...... There are rules and restrictions outside, and it is impossible for us to do it ourselves...... Can ......"

"The first section may not be the strongest force of the sub-bureau...... In my opinion...... The strength of Han Dao, the head of the third section, is far superior to those fools in the first section!"

"What do you mean...... But that one is ...... after all."

"Shhh......h It's business...... The order sub-bureau has always been clear about public and private, don't you understand, Deputy Director Gong? ”
