The third child didn't see anything, you must know that it was daylight, and he could see it from the wall of the "Sun Never Sets Fortress" all the way to the Demon Realm camp, but he didn't see any enemies in his field of vision.

But the cacophony of sirens in the ears did not seem to be fake, and it was clear that the enemy was rushing towards them in a way they could not see.

"Where is the enemy?"

It was not only the third child who had this kind of question, but many of the soldiers who heard the alarm rushed to the city wall with a blank face, and the magic crystal cannon on the city wall did not know where to aim.

The old man landed another punch on the third child's head: "This stupid bastard!

Before the old man could finish speaking, the entire ground trembled violently, obviously something hit the city wall, although the power was huge, but the entire surface of the city wall flashed a layer of soft light, these lights spread like ripples, and the city wall was still intact.

This is the foundation of the city wall being able to resist the attack of the demon world, if it was just a city wall built with bricks and stones, it would have collapsed under the attack of the demon king army, and the reason why the city wall is so strong is because of the strong linkage magic array to support it.

This magic array is the foundation of the strength of the "Fortress on which the Sun Never Sets".

This huge linkage magic array is composed of three large magic crystals and countless small magic crystals, of course, the three large magic crystals are in the three cities of the "Sun Never Sets Fortress", under layers of protection, and the remaining small magic crystals are placed in a small fortress every once in a while, even if these small sunglasses are temporarily damaged, as long as they are not damaged in a large amount of time in a short period of time, it will not affect the overall power of this linkage magic array.

This linkage magic array will not be activated at will in the face of the attack of the demon realm in ordinary times, after all, the power of the magic crystal is not unlimited, as the so-called ants bite the elephant to death, if it keeps the defensive state all the time, it will definitely not be able to hold it.

The effect of the linkage magic array is to automatically open up in the face of the more powerful attacks of the demon world, the kind of attacks that are enough to damage the "Sun Never Set Fortress", and disperse the power to the entire "Sun Don't Fortress", the length of this fortress is amazing, and after dispersing such a huge force, it will naturally be able to withstand it.

As long as it is strong enough, it will be absorbed by the linkage magic array, and the only people who can attack the fortress are ordinary soldiers of the demon realm, and it is of course impossible to tear down this magnificent city wall with that level of attack.

This linkage magic array also has a second function, that is, the forbidden air, which can pull down the demons who have the ability to fly in the demon world, after all, humans can't fly, so that they can pull the other party to the same level as themselves.

The huge impact just now shook the entire city wall, but in fact, the damage that actually fell on the city wall was not great, which also confirmed that the enemy was indeed from the ground.

The ground near the city wall crumbled, and a huge figure sprang out of the ground.

From the appearance, this demon is like an earthworm, the body is a long barrel shape, and there are no eyes, but the size is too huge, and the front end of the body is suddenly raised, and it is actually higher than the city wall.

"Creeper!"

The old man gasped, he knew the name of this kind of monster, this kind of monster is not a rare monster in the demon clan, but it is rare to see such a large size.

More cracks of the ground followed, and the "creeper" was not the only one, there were one of these monsters every kilometer in front of the entire city wall, and each one was almost the same size as the one in front of it, standing taller than the city wall.

"Why are you still stunned, go on!"

The old man kicked away the soldier who was stunned in front of the magic crystal cannon, and activated the magic crystal cannon with his own hands.

The magic crystal cannon is a weapon powered by the magic crystal, which is also a kind of machine, which can extract the energy in the magic crystal to form an energy projectile and launch it, depending on the different loading of the magic crystal, the power of the magic crystal cannon is also unlimited, but even if it is an ordinary magic crystal, it can also fire a blow equivalent to a third- to fourth-order magic envoy, which is already very powerful.

Of course, the cost of each magic crystal cannon is also quite expensive, and if it weren't for the Brave Temple's thousands of years of wealth, it would never have been possible to carry so many magic crystal cannons for the "Sun Never Sets Fortress".

The magic crystal cannon launched by the old man is one of the main guns to defend the "Iron Soldier City", the magic crystal loaded is very large, and the power is of course amazing, and a purple light bullet flies through the clear traces and flies towards the huge body of the "creeper".

The magic crystal cannon is hugely powerful, and the flaw is that the trajectory is really slow, and the effect on more agile monsters is very poor, but the "crawling" body is so big that even if you close your eyes and open the cannon, you can hit the target.

Sure enough, the shell landed on the "creeper", a huge explosion sounded, the hit part was almost cut off by the lazy waist, the "creeper" let out a painful hiss, and the huge body fell heavily.

"Creeper" is a kind of monster that survives underground, there is not much defense, usually survives by sneaking up on some creatures, and the combat ability is also weak, it is really not suitable for fighting demons, so there has been no "creeper" on the battlefield before.

With the old man's cannon and hoarse roar, the surrounding soldiers finally reacted, and the magic crystal cannon on the city wall quickly fired, and a series of colorful streamers bombarded the "creeper", and many magicians began to chant spells to attack the huge body.

Of course, there are more bows and arrows and throwing weapons of ordinary soldiers, but in addition to weapons such as huge siege crossbows, small arms are not painful for a huge body like a "creeper", and not all magic crystal cannons have the power to kill with one blow like the main cannon controlled by the old man, not to mention that there are many shells that miss.

The old man drew the sword at his waist and commanded the soldiers to enter his post immediately, he also had some doubts in his heart, these "creepers" did not have strong attack ability, they could not have come to send them to death......

After the first wave of attacks, although these "creepers" were painted, most of them did not fall under artillery fire, and it would take a little time for the "magic crystal cannon" to recharge, and the battlefield fell into a brief silence.

A "creeper" roared, and the erected half of its body fell heavily against the wall.

Although the weight was large, it was certainly impossible to crush the city walls with this weight alone, but it only flattened many stunned soldiers.

The "creeper" who fell on the city wall opened its bloody mouth, but it was not meant to eat people, and a steady stream of Demon King Army soldiers rushed out of his bloody mouth!
