It turns out that the world has formed its current pattern 50 years ago. At that time, the epidemic spread very quickly, and many monsters mutated very quickly. In the end, these mutated monsters wantonly invaded human settlements.

The number of human beings is less than one percent of what it was fifty years ago, and there are two dangers facing humans now, one is a monster beast and the other is a half-orc.

As for the formation of the half-orcs, there are still different theories, and there is no definite statement.

The reason why humans built several layers of strong walls was mainly to prevent the attacks of demon beasts and orcs. Every few years, orcs and monsters will tentatively attack human cities, and many cities have been destroyed.

Chu Han bought a copy of the current world map and saw that almost all the existing cities were on the dragon vein.

And our country has three huge dragon veins, and the major cities on these three dragon veins have basically been preserved. But all the cities outside the three dragon veins were destroyed, and not a single one was left.

So now human beings can only deal with monsters and orcs by gathering together, strengthening the city walls, and researching high-tech weapons.

But even with the current high-tech weapons, the basic damage rate is not too large for the constantly mutating monsters and half-orcs.

Now the only one who can directly damage monsters and orcs is the Guigu faction. The Guigu Sect has a long history, and since the Demon Beasts and Orcs have been raging, this sect has grown rapidly.

Even the state asked this sect to train the army, and the Guigu faction lived up to expectations and helped develop some special bullets and methods to deal with demon beasts.

Now in the existing cities in China, almost most of the citizens know more or less how to deal with the little demon.

But to deal with the big demon, it not only requires agile skills, but also years of hard training, and it is not something that can harm it overnight.

The two of them continued to wander around the fourth layer of the city, and he saw the uneven traces of battle everywhere on the city walls, and guessed that this should be the destruction caused by the demon beasts during the siege of the city.

At this moment, the sound of air defense sirens suddenly sounded, and after a while, the gate of the inner city was opened, and the army ran out quickly. On the fourth layer of the runway, outside the fourth layer of the wall, all the craftsmen who built the outer city wall were also quickly transferred back.

But inside the fourth layer of the city wall, the citizens' hearts were only slightly stunned, and then they did their own things as if nothing happened.

Chu Han didn't understand what the situation was, and then Yu Yan walked to a stall and asked, "Big brother, this air defense siren sounded, and I saw that the army came out, what is the situation?"

The other party was originally very annoyed, but seeing that it was such a beautiful beauty, the anger on his face suddenly subsided, and he showed a smile and replied: "Beauty, you are from another city, but it doesn't matter, you don't have to be afraid, our Kyoto City is impregnable, and those demon beasts can't attack it." Something like this, which happens every year or two, is used to it, and every time we are repulsed by our army. ”

After Chu Han saw the inner city army come out, a group of people in camouflage uniforms came out, each of these people carried a sword behind their backs, two pistols pinned to their waists, and a machine gun in their hands, all dressed up like the people he had seen before.

Chu Han opened his mouth and asked, "Hey, big brother, who are these?"

When the eldest brother saw that Chu Han was so handsome, he ignored it with a look of contempt, and did not answer him with a straight face.

Seeing this situation, Yu Yan snickered in her heart, so she asked: "Big brother, we are from the outer city, we don't have such a situation over there, I want to ask these people what they are doing next to him?"

The eldest brother looked at Yu Yan and replied with a smile: "Those people, they are wanderers, you see they are dressed in camouflage uniforms, and they are equipped with the most advanced weapons. They are not only responsible for assisting the army in guarding the city, but also responsible for purchasing and escorting equipment out of the city, all of which are trained by the Guigu faction, and they can be regarded as disciples of the Guigu Gate. ”

When the wanderer team walked past Chu Han and Yu Yan, the leader of the leader suddenly looked back at Chu Han, Chu Han looked at him, both of them frowned, and did not speak, the leader turned around and continued to quickly lead the team towards the city wall.

In Chu Han's opinion, the skill of this leader should not be low.

Through the information that Chu Han and Yu Yan learned, they already felt extremely unfamiliar with this world, and although there were many high-tech weapons in this world, due to a lot of mineral resources and other resources, they were attacked by demon beasts and half-orcs.

The resources here have also become extremely scarce, and the others are okay, after all, everyone is basically in the city now, and you can't go out of the city without permission, but the medicinal materials in the city are very scarce, and there are demon beasts and half-orcs everywhere in the outside world.

In the city, you can only organize a team of wanderers, let them go out of the city to collect medicinal herbs or transport supplies to other cities. And every Rover squad is almost. There is a person from the Guigu Gate.

The man looked a little nervous when he saw Yu Yan, and said with a smile: "Beauty, you don't have to be nervous, it's okay." ”
