Wiener City is the territory of the military assassins, and even if the branches of other big forces are here, they dare not target the military assassins, because they will inevitably pay a heavy price if they do so.

Unless it can get the support of the headquarters, but rashly offending a killer organization like the military assassination, once it is not successful, the final consequences will be unbearable.

What's more, it will lose the interests of Wiener City.

It is for this reason that the city of Wiener has always maintained a unique balance that has never been broken.

Several of the elders of the military assassin glanced at each other, and their hearts were shocked at the same time, it seems that Bai Shicheng is indeed smart enough, and he would rather tear his face with them and give up the position of the leader of the military assassination, and he must flee here in advance, most of them guessed something in advance.

At this time, they also regretted it a little, they should have obeyed Bai Shicheng's orders at that time, I am afraid that at this time, they have left smoothly.

It's just that there is no regret medicine in the world at all.

The most important thing at the moment is to try your best to block the attack of the Underground World Alliance, if you really wait for the opponent to break through all the defenses and take the base.

When the time comes, they won't even have the slightest chance of saving their lives.

It's just that the strength of the Underground World Alliance is strong, and since they have already launched an operation, the chance of failure is extremely slim, so they are not completely sure that they will be able to survive this catastrophe.

But taking the initiative to surrender is definitely not their choice.

Thinking of this, several elders made a decision in their hearts at the same time and hurried to the forefront of the battle.

As they progressed, the sound of the battle grew louder and more intense, and the aftermath continued to be heard, and the worries in their hearts became more and more intense.

A few minutes later, the second line of defense was finally reached.

This is the most important line of defense on the periphery of the military stab base, once it is breached, the entire base will no longer have any secrets, and will be completely exposed to the enemy's sight.

Ahead, the members of the assassin had completely abandoned the means of killers, and firmly guarded the front line, using various shields to launch a fierce battle against the enemy.

Dadada............

Every now and then, a burst of gunfire rang out, and an enemy fell.

But in the same way, the stabbing men are also constantly dying, and this sacrifice is even greater than that of the enemy, even to the point where they can hardly bear it.

Especially the enemy's lifeless fighting style, even if he died, he would do everything he could to pull the person with the military assassin to be buried together, and this spirit shocked several elders.

In such a situation, they felt the Grim Reaper constantly approaching them.

The end is coming!

Several elders glanced at each other, and within ten minutes, the defense line in front of them would inevitably be breached, and there was only one last way to resist the enemy's crazy attack.

Save the living forces, all retreat into the last line of defense of the base, and also need to take out all the hole cards prepared when establishing the base, so as to have a chance of life.

However, even if there is only one glimmer of life, they must fight desperately.

Suddenly, several elders waved their hands and took the lead in retreating towards the depths of the base.

The members of the spur who were still holding on to the defensive line also began to retreat in an orderly manner, and from time to time, they used the weapons in their hands to launch counterattacks.

Gradually, the retreat entered the depths of the base.

"Kill, the enemy has begun to retreat, give me the victory to pursue, absolutely not let the enemy escape. On the side of the Underworld Alliance, a voice full of murderous intent sounded.

In an instant, a large number of people came out and launched a fierce pursuit.

"Let's go too. ”

Xiao Yunfei's eyes flashed, and he jumped up and took the lead in pursuit.

Behind him, many masters in the martial arts world followed closely, and they also knew what Xiao Yunfei meant, and they must end this battle as soon as possible, otherwise the turmoil caused would cause great changes.

More importantly, they need to arrive before the enemy retreats into the last line of defense, and only then can they avoid heavy casualties.

You know, this is the headquarters of the military thorn, and no one can guarantee that the military thorn has no other hole cards.

What's more, the active retreat of the military assassins is a good proof that their guess is not wrong, and they want to rely on the last hole card to start a maneuver with them.

It is precisely because of this that these masters must go all out, otherwise, the final loss will reach a point that they cannot bear.

A few jumps, more than a dozen figures swept by.

Soon, he had already caught up with the retreating stabbing members, and the killing moves in his hands were frequently used, constantly killing the enemy, and constantly advancing.

A bloody path is here.

With almost every move, an enemy is bound to fall in a pool of blood.

Under such an impact, the attack can be described as very smooth, and in a moment the distance from the enemy was narrowed, forming a fierce battle of containment.

In a short period of time, the military assassins paid an unbearable price.

What's more, if this situation continues, I am afraid that it will be extremely difficult for them to even retreat into the last line of defense and take out the last hole cards.

For a moment, the faces of several elders became extremely gloomy.

They looked at each other and exchanged words silently before making a decision.

Suddenly, I saw several elders jumping up, rushing out in all directions, and using the favorable terrain nearby, they launched a counterattack against Xiao Yunfei and other masters.

Two of the elders kept moving, still quickly retreating towards the depths of the base.

Obviously, they did this with the intention of fighting one last time.

If you really can't retreat into the last line of defense, then taking the last hole cards here to fight is not without a chance to repel the enemy.

As long as they can repel the enemy, then their lives can be saved, and such a result is their real goal.

With the Underground World Alliance attacking, this base is trying to be saved, obviously there is no chance, and if you are not careful, you will lose your life.

Faced with the threat of death, they can only make a last-ditch effort.

Da Da Da ......

The gunshots kept ringing out, and Xiao Yunfei and the others did slow down, but relying on their excellent skills, they were still moving forward.

However, the ordinary masters who attacked behind them suffered greatly and could hardly move forward.

What's more, many people were hit by missiles and fell to the ground injured and screamed in pain.

Of course, not only were they injured, but many of the stabbers were also injured by mistake, but those elders obviously couldn't take care of that much, and now there was nothing more important than holding back the enemy's advance and taking out the last hole card for the last fight.

For a moment, blood flowed sideways and stained the ground red.

Xiao Yunfei's face became even more gloomy, his eyes flickered, full of strong killing intent, and said, "It's not okay to go on like this, Dragon Pavilion Master, Nangong Family Master, do you have the courage to accompany me to go deep alone?"

If you want to change this situation, there is only one way.

After all, the lone army is deep, and no one dares to guarantee what kind of danger there is in the depths of the base of the military assassination.

Even if Xiao Yunfei's strength is strong, he has great confidence in himself, and he also knows that with the addition of thermal weapons, any change may happen.

However, in order to reduce the losses of his own side, he had to take a risk.

Of course, going alone, Xiao Yunfei would never do such an idiotic thing.

Call the other two, at least they can take care of each other, with the strength of the three of them, even if they encounter danger, it shouldn't be too much of a problem to get out in the end.

"Good. ”

The Dragon Pavilion Lord and the Nangong Family Master, who were following Xiao Yunfei, glanced at each other and agreed without hesitation.

They are also aware of the situation in front of them, so why take a risk?

When they went to assassinate the high-level of the Anti-Earth Alliance, they had already put life and death on the line, so naturally they would not be afraid of the danger in front of them.

I don't know how much safer it is now than it was then?

Immediately, the three of them jumped to their feet, dodging the bullets flying in the air, and at the same time jumped quickly, stepping on the shoulders of the enemy and moving quickly.

In just a few moments, it had advanced more than ten meters.

Dangerous!

Terror!

The faces of several military assassin elders hiding in the shadows suddenly changed greatly, and they shot even faster, they knew that they had to stop Xiao Yunfei's three masters.

Otherwise, all the calculations made would have been in vain.

It's just that a master who has reached Xiao Yunfei's realm, the threat that a thermal weapon can cause is already very weak, unless it is a weapon with great damage that may be able to stop them.

As for showing up to block it, they don't have the guts to do it.

You must know that the strength shown by Xiao Yunfei and the others before is far from what they can deal with, if it is in the case of assassination, there may be a glimmer of opportunity.

But in a head-on battle, there is no chance of victory.

It was precisely like this, Xiao Yunfei and the three of them were like entering a no-man's land, and in just a minute or two, they had already broken through many obstacles and swept towards the depths of the base.

Seeing this scene, the faces of several military assassin elders hidden in the dark changed greatly, and they got up at the same time, gave up the blocking in front of them, and followed closely in the footsteps of Xiao Yunfei and the others.

Their idea was very simple, that is, to keep up closely, cooperate with the people in the depths, and take advantage of the numerical advantage to take the lead in solving Xiao Yunfei's three enemies.

After the battle just now, they had already seen that Xiao Yunfei was the real leader of this group of enemies.

If the calculations do succeed, it is not impossible to remove this danger.

So, in order to save your life, you have to take this risk.

One after the other, through the heavy defense lines of the base, Xiao Yunfei and the three of them were not hindered much, and they had already successfully arrived at the deepest part of the base.

In front of a concave room with complex topography.

They also sensed that someone was following behind, but they didn't care, until they found the terrain in front of them, Xiao Yunfei waved his hand and stopped.

If you enter directly, you will inevitably suffer from the danger of being attacked from both sides.
