"Shrink the line!"

At about 4 o'clock in the afternoon, when the third line of defense was breached, Sawyer had to give the order to shrink the line.

For a while, tens of thousands of strong men who were fighting on the periphery gave up their opponents, turned around and rushed in the direction of Blue City, and the spellcasters behind the defense line were full of firepower, and countless spells turned into torrents to cover the entire battlefield.

And after everyone retreated into the fourth city wall, the tower of the blue city was also lit up with a bright ring of fire again, and the blazing white sea of fire appeared again, but it was around the fourth city wall for a long time, the flames were so fierce and the sea of fire was so wide that even the super-level black beasts could not cross it.

Taking advantage of the fact that the Black Tide was blocked by the sea of fire, the soldiers, mercenaries, and strong men directly abandoned the fourth city wall, crossed the unused fifth city wall and the half-built sixth city wall, and all retreated towards the blue city.

Under the cover of Sawyer, eleven lords, and more than two hundred titled knights who were still ready to fight, it took Kuroshio a full ten minutes to break through the blockade of the sea of fire, but it was limited to super-level black beasts and the top high-level black beasts, and when Kuroshio weakened the sea of fire to the point where all high-level black beasts could pass through, the time had passed almost half an hour.

In this half an hour, not only did all the soldiers and mercenaries withdraw to the Blue City, but even the city defense equipment that could still be used was dismantled and transported back to the Blue City by the engineering team and transport team that had been prepared for a long time.

"It's a fight against the odds."

Sawyer returned to the head of the Blue City, looking at the sea of fire that was gradually extinguishing and the black tide that was slowly advancing, and couldn't help but sigh.

If it weren't for the situation, he didn't want to shrink the defense line and return to the blue city, but there were too many dead, and the army responsible for defending the city wall was reduced from the original four echelons to three echelons, and in order to be able to completely resist the impact of the black tide, it was reduced to two and a half echelons.

And the strong men on the front line are also facing the same problem, companions are gradually becoming scarce, and everyone is under more and more pressure, even if Sawyer and the lords shift the focus of the battle from slaughtering the beast tide to supporting their comrades, they will not be able to stop the increase in the speed of attrition.

In the end, Sawyer had to give the order to shrink the line.

It is true that returning to the Blue City to shrink the defensive line can reduce the number of people needed to defend it, while increasing the density of the strong and increasing the ability to defend against the Kuroshio, but it is also disadvantageous.

The most direct is the reduction of the fault tolerance rate, when all the strong people are gathered under the city wall, the density of the strong will indeed rise, but the depth of defense is greatly reduced, and at the same time, for the top powerhouses such as Sawya, lords and knights, the number of super-level black beasts they face has not actually decreased, when Sawa and their top powerhouses are contained, the remaining super-level black beasts can easily pass through the defense line composed of the remaining powerhouses, and directly slaughter the knights and big knights under the city wall.

Even Sawyer and the lords didn't even have time to return to help, and they didn't dare to let go of the opponents who were entangled with them to return to help, and those super-level black beasts that broke through the outer defense line could only be handed over to the big knights in the rear to block - relying on cooperation, relying on secret methods, and even, relying on life.

What is even more serious is the prolongation of the war.

After shrinking the defensive line, the speed of killing the black beast will inevitably decrease, and the original three-hour battle time is likely to be extended to five or six hours, or even seven or eight hours!

And now for everyone, what is the most affecting combat effectiveness?

Not strength, not soul power, not mental power, but exhaustion.

Spells can heal injuries, replenish strength, and even make up for mental power, but they can't erase the fatigue of the soul, this high-intensity battle that lasted for more than twenty hours, so that everyone's hearts are on the verge of collapse, not only the frequency of mistakes has increased greatly, but even soldiers died suddenly on the battlefield!

If the battle were to be extended for a few more hours, how many people would have died on the spot at the moment of victory, even if the victory had been achieved?

When Sawyer was worried about these problems, the knights with titles around Sawyer laughed: "Only by fighting against the water can you survive!" ”

"Ha," Sawa laughed as well, letting go of his worries, and his voice full of fighting spirit resounded throughout the city, "Then fight!" ”

"Fight!"

"Fight!"

"Fight!"

……

At this moment, roaring into the sky, even the black tide in the distance seemed to be shocked by this sky-rushing battle intent, and the speed of advancement was actually a few points slower!

At this moment, everyone's eyes looking at the black tide are full of fighting intent, no one flinched, the cowardly has already died in the impact of the beast tide, only the brave can find that glimmer of life in the endless beast tide, and those who can survive until now are the most tenacious people!

And the half-hour that Anoke had bought for them before also made them recover a little tired, although it was not enough for them to return to their peak, but now, it was enough to fight!

However, Sawyer and the other lords sighed in their hearts: "You have learned wisely. ”

The cessation of the beast tide was not because of everyone's high fighting spirit, but waiting, waiting for the sea of fire in the rear to be extinguished, waiting for those black beasts as cannon fodder to rush to the city, consume the city's defense equipment for them, and contain the strong people who could stop them.

"What if you become smarter?" Sawyer threw away the long sword full of cracks in his hand, reached out and pulled out a straight knife from the waist of the soldier behind him, and held it lightly in his palm, and the brilliance shrouded the blade in an instant, and also illuminated the sneer on his face, "This city, but you can't break it!" ”

Hearing this, the fighting spirit of the surrounding soldiers became a little stronger, and they clutched the weapons in their hands, but no one roared - every bit of physical strength must be used where it should be used!

Only one soldier, whose face was gloomy, silently left the wall, his lips opening and closing, as if repeating three words.

But at this moment, there was an ethereal voice in the distant sky, which seemed to praise a great existence, and seemed to be depicting a beautiful world, which made people involuntarily listen.

Gradually, the soldiers at the head of the city began to gradually immerse themselves in the carol, their eyes were misty, their expressions were pleasant, but there was no half of the fighting spirit on their bodies, and some even wanted to jump off the city wall desperately to listen to the carol closer.

Not even just soldiers, but even transporters, craftsmen, and civilians in the rear...... Almost all the ordinary people in the city were attracted by this carol, and involuntarily put down the affairs in their hands, and looked up in the direction from which the carol came one by one, their eyes seemed to be full of happiness, but there was no trace of life.

When the carol came, even Sawyer's mind was shaken for a moment, but soon he came to his senses, looked at the people who were bewitched by the carol, and couldn't help but shout, "Wake up! ”

But under the shroud of the carol, Sawyer's voice seemed to be restrained by an invisible force within a hundred meters, within a hundred meters, the sound waves were raging, and the soldiers and mercenaries were also shocked to spit blood while waking up, and even some weaker knights had blood oozing blood in their ears, but a hundred meters away, people were still immersed in the carol and could not extricate themselves.

The other eleven lords were in a similar situation to Sawyer, the ode did not confuse their powers, but it did keep their power within a certain range, making them powerless to awaken the others.

The sound of the carol became clearer and clearer, and even the knights and great knights in the city were powerless to resist the power of the carol, and gradually lost themselves in the carol, and in the end, only the most powerful knight with the title was left with the ability to resist the power of the carol, but they could not completely block the power of the carol, they struggled one by one, and even blood and tears flowed from their eyes, and in the end they could only barely control their bodies, but they were powerless to wake up others.

In the strange chants, the entire Blue City's defense line was paralyzed in an instant.
