“Shrink the defense line!”

At around 4:00 pm, when the third line of defense was broken, Soya had to issue an order to shrink the line of defense.

For a moment, tens of thousands of strong men fighting on the periphery gave up their opponents and turned around and rushed towards the direction of Blue City. The casters behind the defense line opened fire and countless spells turned into torrents to cover the entire battlefield.

After everyone retreated into the fourth city wall, a dazzling ring of fire lit up again on the tower of Blue City. The blazing white sea of ​​fire appeared again, but it surrounded the fourth city wall for a long time. The flames were so fierce and the sea of ​​fire were so wide that even the black beasts could not cross it.

Taking advantage of the dark tide being blocked by the sea of ​​fire, the soldiers, mercenaries and strong men directly gave up the fourth city wall, crossed the unused fifth city wall and the sixth city wall that had been built halfway, and all retreated to the Blue City.

Under the cover of Sawyah, eleven lords and more than 200 titled knights who were still in battle, it took Kuroshio ten minutes to break through the blockade of the Sea of ​​Fire, but it was limited to the level black beasts and the top high-level black beasts. When Kuroshio weakened the sea of ​​Fire to the point where all the high-level black beasts could pass, it was almost half an hour long.

In this half hour, not only all the soldiers and mercenaries retreated to Lancheng, but even the city defense equipment that could still be used was dismantled by the engineering team and transportation team that had been prepared and transported back to Lancheng.

"A fight against the enemy."

Sawyah returned to the city of Blue City, looked at the gradually extinguished sea of ​​fire and the slowly advancing black tide, and couldn't help but sigh.

If it weren't for the situation, he wouldn't want to shrink his defense line and return to Blue City, but there were too many people dead. The army responsible for defending the city walls had grown from four echelons to three echelons. In order to completely resist the impact of the Black Tide, it was reduced to two and a half echelons. If he continued to fight, the soldiers might not even have the chance to rotate!

The strong men on the front line also faced the same problem. The companions gradually became scarce, and everyone was under increasing pressure. Even if Soya and the lords shifted the focus of the battle from the slaughtering beasts to supporting their comrades, it would not prevent the increase in the reduction of the number of troops.

Eventually, Sawyer had to order a contraction of the defense line.

Indeed, returning to the Blue City to shrink the defense line can reduce the number of people required for defense, while increasing the density of the strong and enhancing the ability to resist the dark tide, but the disadvantages of doing so are equally serious.

The most direct thing is the reduction of fault tolerance. When all the strong men gathered under the city wall, the density of the strong men will indeed increase, but the defense depth will be greatly reduced. At the same time, for top powerhouses such as Sawyer, the lord and the title knights, the number of rank black beasts they face has not actually decreased. When top powerhouses such as Sawyer and others are restrained, the remaining rank black beasts can easily pass through the defense line composed of the remaining strong men and directly slaughter the knights and knights under the city wall.

Even Soya and the lords didn't even have time to return to help, and they didn't dare to let go of their opponents who entangled them for help. Those black beasts that broke through the outer defense line could only be handed over to the big knights behind to block them - relying on cooperation, secret techniques, and even life.

What's more serious is the extension of the war time.

After shrinking the defense line, the degree of killing black beasts will inevitably decrease. The original three-hour battle time may be extended to five or six hours, or even seven or eight hours!

And now, what is the most influential thing in combat power for everyone?

It is not power, not soul power, nor mental power, but fatigue.

Spells can heal injuries, replenish strength, and even make up for mental power, but they cannot ease the fatigue in their minds. This high-intensity battle that lasted for more than 20 hours put everyone's mind on the verge of collapse. Not only did the frequency of errors increase greatly, but some soldiers even died suddenly on the battlefield!

If the battle time is extended for a few hours, even if the victory is finally achieved, how many people will die on the spot at the moment of victory?

While Sawyer was worried about these issues, the title knights surrounding Sawyer laughed: "Only by fighting with one's back can you survive!"

"Ha," Sawyer also laughed, put down his worries, and a voice full of fighting spirit resounded throughout the city, "Then let's fight!"

"war!"

"war!"

"war!"

...

At this moment, he roared and rose into the sky. Even the dark tide in the distance seemed to be shocked by the fighting spirit soaring into the sky, and the advancement was a little slower!

At this moment, everyone's eyes were full of fighting spirit when they looked at Hei Tide, and no one retreated. The cowardly had already died in the impact of the beast tide. Only the brave could find that glimmer of life in the endless beast tide. Those who could live until now were the most tenacious people!

The half hour that Arnold had won for them before also restored them a little fatigue. Although it was not enough to restore them to their peak, now it is enough to fight!

However, Sawyer and the other lords sighed in their hearts: "You've learned to be smart."

The stop of the beast tide was not because of the high fighting spirit of the crowd, but because of waiting, waiting for the sea of ​​fire behind to extinguish, waiting for the black beasts as cannon fodder to rush up to the city, consuming city defense equipment for them, and restraining the strong people who could stop them.

"What if you become smart?" Sawyer threw away the long sword covered with cracks in his hand, reached out and pulled out a straight knife from the waist of the soldier behind him. He gently held his palms, and the light instantly covered the blade, illuminating the sneer on his face, "This city is not something you can break!"

After hearing this, the fighting spirit of the soldiers around him increased a little more. He held the weapons in his hand tightly, but no one roared - every part of his physical strength should be used wherever he should be used!

Only one soldier's face was dark and he silently left the city wall. His lips kept opening and closing, as if he was repeating three words.

But at this moment, a misty sound came from the horizon in the distance, as if praising a great existence, and as if depicting a beautiful world, people can't help but listen.

Gradually, the soldiers on the city began to gradually immerse themselves in the hymns, their eyes were blurred and their expressions were pleasant, but there was no desire to fight on their bodies. Some people even wanted to jump off the city wall regardless of everything and listen to the hymns closer.

Not only soldiers, but also the transport team members, craftsmen, civilians in the rear... Almost all ordinary people in the city were attracted by this hymn and involuntarily put down their affairs. They looked up at the direction of the hymn. They looked full of happiness, but there was no trace of vitality.

When the hymn came, even Soya's mind was shaken for a moment, but soon he woke up and looked at the people who were bewildered by the hymn, and couldn't help but roar, "Wake up!"

But under the cover of the ode, Sawy's voice seemed to be bound by invisible force within a range of 100 meters. Within 100 meters, sound waves were raging. The soldiers and mercenaries were also shocked to vomit blood while awakening. Even some weak knights had blood marks in their ears. But a hundred meters away, people were still immersed in the ode and could not extricate themselves.

The situation of the other eleven lords is similar to that of Sawyer. This ode does not delude them, but it can limit their power to a certain extent, making them unable to awaken others.

The sound of the hymn became clearer and clearer. On the top of the city, even the knights and the great knights were unable to resist the power of the hymn. They gradually lost themselves in the hymn. In the end, only the most powerful knight with the ability to resist the power of the hymn was left, but they could not completely block the power of the hymn. They all struggled with their expressions, and even blood and tears flowed out of their eyes. In the end, they could only barely control their bodies, but were unable to awaken others.
