Seeing the temporary walls gradually collapsed in the gray tide, Soya, who was standing at the top of the city, nodded with a smile, and was obviously very satisfied with the actions of the soldiers and spellcasters.

When the penultimate city wall collapsed, the gray beasts with flying ability had already arrived in front of the last city wall. The flying gray beasts were like a dark cloud above the gray tide, pressing towards the city wall quickly. However, before they could get close to the black city wall, they lost their ability to fly and fell from mid-air with screams.

Immediately afterwards, flames, frost, and lightning!

The endless spells were like a colorful wave, instantly covering these flying gray beasts that fell to the ground. These gray beasts were erased from this world before they even had time to scream.

At the same time, a large rain of arrows shot out from the blue city wall behind, and roared into the gray tide behind, nailing countless gray beasts to the ground. The lucky gray beasts were shot directly into the vital points and killed on the spot. The bad luck gray beasts were nailed to the ground by the arrows with the power of falling, and only the companions were ruthlessly trampled on them.

But there are too many gray beasts. The rain of arrows shot from the city wall alone cannot stop the advancement of gray beasts. At best, the degree of advancement of gray beasts can only be slightly reduced.

But this is enough. The first six city walls have already bought enough time for the last line of defense. When the gray beasts attacked the first six city walls, not only did the soldiers of Blue City arrive at this temporary defense line, but even the transportation teams traveling between Blue City and the temporary defense line walked back and forth, adding a large amount of combat preparation materials and more spell casting materials to this temporary defense line.

Using these spell casting materials, the spellcasters rebuilt the temporary defense wall and enchanted various abilities such as solid, rebound, and air ban. If the time limit for the existence of the city wall is thrown away, this city wall is no longer much worse than the city wall of Blue City.

While the casters of the change and energy-shaping systems were busy, the other casters were not idle either. Complex magic arrays gradually formed in their hands. The rich energy of heaven and earth turned into thousands of semi-illusory energy vortexes, standing behind the defense line like a wind wall.

"Almost condensed the energy of the entity, the casters in this world are really amazing."

Looking at the energy vortexes standing behind the city wall, Sawyer couldn't help but sigh. Although the number of spellcasters in this world is extremely rare and the violent energy greatly increases the difficulty of casting, it was in such a dilemma that generations of spellcasters spent hundreds or thousands of years pushing the formations of this world to an unprecedented peak.

At least, the mages in the present world cannot do this level.

The strongest spell casters flying in mid-air are just the level of the fourth ring titled mage, equivalent to the half-step mythical power in the present world, and the rest are the fifth ring mages equivalent to the veteran legendary mages, but with the assistance of the formation, they swung out the power of their own realm. Under their hands, each magic array can release power comparable to a true mythical power, and the magic array constructed by the twelve titled mages condenses power comparable to that of old mythical power!

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

Sawyer sighed, and couldn't help looking back, but the two lords standing behind him still looked for granted, as if they were used to the caster's ability to cast a higher level of power with the help of the magic array.

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

However, when the gray tide hit the last embankment of Blue City, it did not destroy the city wall as before. Instead, it was like a stream hitting the river dam. After making waves, it was easily stopped.

"kill!"

A roar came out from the temporary defense line, and countless arrows shot down the spear. The gray beast in the front wailed and turned into a grey mist, just like the mist caused by waves. The gray beast behind still rushed towards the city wall without fear of death, or used its own strength to directly hit the city wall, or climbed up with sharp claws. There were also gray beasts such as gophers and earth demon insects drilled into the ground, trying to cross this line of defense from the ground.

The casters were not willing to fall behind. The magic arrays lit up one after another, and the gathered energy turned into violent magic power to press forward, fire rain, ice fog, thunder clouds, earth thorns, cuteness, and mysterious explosion... A large area of ​​spells surrounded the temporary defense line, like a sieve, filtered through 99% of the gray beasts. Even if a few gray beasts luckily passed through the spell blockade, they were unable to cross the swords of the warriors anymore.

At the same time, there were spells deep into the ground, and the ground in front of the city walls cracked from time to time, and a gray mist appeared, and it was flattened by the gray beasts that followed one after another, as if nothing happened.

Just after the casters and warriors formed a perfect defense net, the rain of arrows from the city walls in the rear gradually stopped. After all, the only one responsible for maintaining the rain of arrows was the militia temporarily trained by farmers and miners. Although their strength was almost the same as that of the Nine-ring warriors, they lacked combat experience and did not save physical strength during combat. After maintaining the high-intensity rain of arrows for a few minutes, they all lost their strength and lost the strength to pull the bow.

"not bad."

Sawyer was quite satisfied with the performance of these militias. At least these militias were able to shoot enough rain of arrows according to the plan to gain enough time for the casters on the front line to complete the arrangement of the magic circle, and no arrow fell into the temporary defense line. For these militias who had only been trained for three or five days, this performance was perfect.

"Let the militia rest on the spot and prepare to suppress the arrow rain again during shifts."

Sawyer ordered, and two commanders immediately waved flags to both sides and passed on Sawyer's orders layer by layer. In just a few minutes, this order was passed on to each section of the city wall.

However, after this scene fell into Sawyer's eyes, he sighed. This method of sending orders was still too primitive and inefficient.
