Watching the makeshift walls gradually crumble in the gray tide, Sawyer, who was standing at the head of the city, did not move, but nodded with a smile, obviously satisfied with the methods of the soldiers and spellcasters.

When the penultimate wall collapsed, the gray beasts with the ability to fly had already rushed to the last wall, and these flying gray beasts were like a dark cloud above the gray tide, quickly pressing towards the city wall, but before they could get close to the black wall, they lost their ability to fly, and fell from the air screaming.

Immediately after, fire, frost, thunder and lightning!

The endless spells were like a wave of colors, instantly covering the flying gray beasts that fell to the ground, and the gray beasts were wiped out of this world before they even had time to scream.

At the same time, a large rain of arrows also shot out from the blue city wall behind, screaming and falling into the gray tide behind, nailing countless gray beasts to the ground, the lucky gray beasts were directly shot at the vital point and killed on the spot, while those who were less lucky were nailed to the ground by the arrows with the power of falling, and they were greeted only by the ruthless trampling of their companions.

However, there were too many gray beasts, and the rain of arrows shot from the city alone could not stop the advance of the gray beasts, and at best, it could only reduce the speed of the gray beasts' advancement a little bit.

But that's enough, the first six city walls have bought enough time for the last line of defense, and when the gray beast attacked the first six city walls, not only the soldiers of Blue City rushed to this temporary defense line, but even the transport teams that traveled back and forth between Blue City and the temporary defense line walked back and forth, replenishing this temporary defense line with a large number of combat preparation materials, as well as more spell casting materials.

Using these spellcasting materials, the casters rebuilt the walls of the temporary defense line, and enchanted them with a variety of abilities such as solidification, rebound, and forbidden space, and if you don't look at the time limit of the wall's existence, this wall is not much worse than the wall of the Blue City.

When the casters of the change system and the plastic energy system were busy, the other spellcasters were not idle, and complex magic circles gradually took shape in their hands, and the rich heaven and earth energy was attracted by the magic circle, turning into thousands of semi-illusory energy vortices, erected like a wall of wind behind the defense line.

"Almost condensed the energy of the entity, the spellcasters of this world are really powerful."

Looking at the energy vortexes erected behind the city wall, Sawyer couldn't help but sigh, although the number of spellcasters in this world was extremely rare, and the violent energy greatly increased the difficulty of spellcasting, but it was in such a predicament that generations of spellcasters spent hundreds of thousands of years to push the formation of this world to an unprecedented peak.

At least, this is not the case with a mage in this world.

These spellcasters flying in mid-air, the strongest strength is only the level of the four-ring titled mage, which is equivalent to the half-step mythical powerhouse in the current world, and the rest are the five-ring archmage who is equivalent to the senior legendary mage, but with the assistance of the formation, they have exerted a power far beyond their own realm, under their hands, each magic circle can release a power comparable to that of a real mythical powerhouse, and the magic circle constructed by the twelve titled mages has condensed the power comparable to the old mythical powerhouse!

This is enough power to crush the Lord of the Three Rings!

Sawyer sighed, and couldn't help but look back, only to find that the two lords standing behind him still looked like they were taken for granted, as if they were accustomed to the caster being able to use the magic circle to cast a higher level of power.

In the distance, the gray beast's line was still advancing, like a mudslide, slowly but firmly approaching the last wall.

However, when the gray tide hit the last embankment of the Blue City, it did not break down the wall as before, but like a stream hitting the barrage dam, it was easily stopped after a wave.

"Kill!"

There was a roar of rage from the temporary defense line, countless arrows and spears flew down, and the gray beast in the front wailed and turned into a gray mist, just like the mist stirred up by the waves, and the gray beast in the rear still rushed to the city wall without fear of death, or used its own strength to directly impact the city wall, or used its claws to climb up, and there were gray beasts such as gophers and goblin insects that drilled into the ground, wanting to cross this defense line from the ground.

The spellcasters were not far behind, and the magic circles lit up one after another, and the gathered energy turned into violent magic and pressed towards the front line, fire rain, ice mist, thunderclouds, ground thorns, selling cute, and arcane explosion...... A large area of spells and then surrounded the outer circle of the temporary defense line, like a sieve, filtering through ninety percent of the gray beasts, even if a few gray beasts were lucky enough to pass through the spell blockade, they were no longer able to cross the blades of the warriors.

At the same time, there were spells that went deep into the ground, and the ground in front of the city wall cracked from time to time, and a gray mist appeared, and it was trampled flat by the gray beasts that came forward one after another, as if nothing had happened.

After the caster and the warriors formed a perfect defensive network, the rain of arrows from the rear city wall gradually stopped, after all, the people responsible for maintaining the rain of arrows were only the militia temporarily trained by farmers and miners, although their strength was almost the same as that of the nine-ring warriors, but after all, they lacked combat experience, and they would not save physical strength during the battle, and after maintaining a high-intensity arrow rain for a few minutes, they lost their strength and lost the strength to draw the bow.

"Not bad."

Sawyer was quite satisfied with the performance of these militiamen, at least these militias were able to shoot a sufficient amount of arrows according to the plan, buying enough time for the casters on the front line to complete the formation of the magic circle, and not a single arrow fell within the makeshift defensive line, which was perfect for these militiamen who had only been training for three or five days.

"Let the militia rest on the spot and prepare for another rain of arrows to suppress during their shifts."

Sawyer gave an order, and suddenly two heralds waved the command flag on both sides, passing Sawyer's order layer by layer, but in a few minutes, this order was transmitted to every section of the city wall.

However, after this scene fell in Sawyer's eyes, it made him sigh, this method of passing orders was still too primitive and inefficient.

And at this moment, the spell fluctuations on the front line suddenly became calmer, the violent spells shrouded in front of the city wall gradually converged, and even the energy vortex in mid-air was faint to the point of being invisible, Sawyer's face suddenly turned grim, and the second stage of this warm-up battle was about to begin!
