With the arrival of troops, the originally empty city walls also became busy, and there was a hustle and bustle everywhere.

Under Chu Yi's order, all units of the regiment were stationed in various combat posts, and various new weapons and equipment were erected and debugged, and this war fortress slowly showed its terrifying fangs.

For several days, the city walls were busy, and I don't know how many weapons and equipment were constantly transported to the walls, and then either erected to various battle fortifications or stored in ammunition depots in the city walls.

And Chu Yi, for several days, has been running around on this section of the city wall in the south, arranging the deployment of troops, and is familiar with the firepower deployment in various places on this city wall.

Just on the southern city wall, there are more than 20,000 basic troops, and there are countless light and heavy weapons of all kinds on the city wall.

The artillery position behind the city wall has more than 1,000 heavy artillery pieces of all kinds, and the firepower of the four city walls combined, just one round of blows is completely enough to completely turn this encirclement upside down!

The reserve support of the southern wall alone reached the size of two infantry divisions, twice the strength of the defensive force of the front wall.

There is also an army brigade on standby behind each wall, and according to the perspective of a modern war, the firepower arrangement of this encirclement of the city wall is definitely a serious surplus of firepower.

But with the signing of agreements between the nations and the sharing of battlefield intelligence against barbarian invasions, no one in the know would have thought that the line of defense would be impregnable.

The terrifying individual strength of the low-level barbarians, after they are familiar with the rhythm of modern warfare, is enough for them to avoid most of the firepower attacks.

Not to mention the barbarians with higher cultivation, in the war against the barbarians in the United States, there were barbarians like legendary gods and demons, and even heavy artillery could hardly pose any threat to them......

In this war, before the human martial arts reached a height, the power of the individual was undoubtedly extremely small, and it had to rely on the scientific and technological power that the human race thought was the pillar.

Standing on top of the city wall, looking at the extremely conspicuous spatial crack in the central area, Chu Yi couldn't help but glance at the zero energy on the vision skill panel, and couldn't help frowning.

Energy has a lot of effects, cultivation, healing...... Now that I suddenly have no energy, I always feel that there is something missing......

"Isn't it time to go to another time and space to get some energy?"

This thought flashed in his mind, Chu Yi moved a little, and now with his martial arts cultivation, Chu Yi felt that as long as he was careful, it should not be too difficult to survive in another time and space.

Thinking around, Chu Yi finally gave up this idea, the defense line was initially decided, and as the supreme commander of this city wall, it was the most important thing to do here.

Moreover, what is lacking is time, and the republic needs time to accumulate strength, and to go to another time and space by itself is to destroy the overall strategic situation.

If you attract the barbarians to invade, you will be guilty of greatness!

"Bang!"

Just as Chu Yi was thinking, a red signal flare suddenly shot up into the sky.

Stomp ......

The moment the signal flare sounded, the defense of the entire city wall also moved, and the cultivation soldiers from all over the city quickly rushed to various combat posts, and the battle seemed to be about to break out.

"Barbarians!"

When he saw the figures in front of the spatial crack clearly, Chu Yi's face instantly became solemn, and the most worrying thing still happened!

"They must not be allowed to go back alive!"

The thought flashed, and Chu Yi gave the order without hesitation.

"Bang ......"

A few dull sounds sounded on the city wall, and then I saw a few barbarians in front of the spatial crack explode in an instant, and the stumps and severed arms flew sideways.

At this time, no one cared about the life or death of these barbarians, and everyone's eyes were focused on the dark and secluded spatial crack, waiting tormentedly.

For the soldiers at the bottom, perhaps it is more of an expectation, such a terrifying defensive force, in their opinion, maybe this war is a massacre.

But for Chu Yi and other insiders, even if war is inevitable, the later the better, whether it is science and technology, or martial arts, it takes time to accumulate strength, and the republic, and even all mankind, need time!

Stalemate, stalemate.

On the city wall, nearly 100,000 soldiers were at a stalemate against a spatial crack, just because of the appearance of those few barbarians.

After a long time, the spatial crack was still so quiet, without a trace of fluctuation, and the soldiers relaxed a little.

"Pass the order, all departments strictly implement the 24-hour combat duty system, and no personnel on duty are allowed to leave their combat posts without authorization, and those who dare to violate it will be dealt with by military law!"

"Also, let the Army Airlines send a helicopter over!"

Chu Yi stared at the spatial crack in front of him and gave an order to the officer beside him.

Soon, a helicopter landed on the city wall, and before it could stop, Chu Yi jumped into the cabin.

"Go to the spatial rift!"

The helicopter then spiraled and flew straight towards the rift in space.

"You don't have to land, just drop the rope and stop here. ”

When the helicopter arrived above the space rift, Chu Yi glanced at the crack underneath, and jumped out of the helicopter after saying a word.

However, the height of more than 20 meters had no effect on Chu Yi, and after landing, the stumps and broken arms everywhere also came into Chu Yi's eyes.

There was not the slightest discomfort with this bloody scene, the barbarians, not my race, it didn't matter how many and how miserable they died.

"Five barbarians, none of them escaped. ”

Glancing at the severed arm of the corpse on the ground, and after drawing a conclusion, Chu Yi felt a little relieved.

After four rounds around, Chu Yi picked and picked up among the barbarian's corpses and broken arms, and the items that the barbarians carried with him were also placed together.

Three maps, a few weapons, five paper books, a few tokens and some sundries.

Wrapping these things, Chu Yi couldn't help but glance at the space crack that was close at hand, but an idea came to him, but the reason in his heart still suppressed the idea.

The situation is unknown, so we can only sit back and see what happens!

Jumped into the air, grabbed the rope dropped by the helicopter directly, and after a few jumps, he entered the cabin.

"Go back. ”

After speaking, Chu Yi looked at the map in his hand, the three maps were very detailed, but obviously they were not from the hand of one person.

Although I can't read the oracle bone inscription of the barbarians, just the shape of the mountain and the landform, I can clearly see that this is a map of the mountains near the spatial rift.

And there seem to be many places marked on the map, and each marked point is annotated with dense small print.

The map was put down, and Chu Yi looked at the tokens.

Metalwork, the material is unknown, but it looks like a standard equipment, and each token is the same size and engraved font.

Five tokens, corresponding to five people.

Tokens are standard equipment again!

The text on the paper album is also the same, and it is clear that it was also issued uniformly......

A bad guess surfaced in Chu Yi's mind.
