Cao Hong thought in his heart, his face was a little bit bold, and he said in a stiff tone:

"Three months! I'll only give you a three-month covenant, don't blame me for saying something ugly, your entire clan hasn't broken through the defense line of the Wolf Tooth Legion for so many years, I don't know if your combat power can meet my standards! ”

Ryan was anxious to speak, Cao Hongyi waved his hand and said: "No need to explain, you will want to form an alliance with me, you should want to take advantage of the destruction of the three major legions to make a big move." I don't know if you have any way to conquer the border strongholds, and I don't bother to bother with it. As an ally of the Offensive and Defensive Alliance, the most I can do during the Covenant is to make strategic feints to match your actions, and not to attack you actively!

If you want, then we will sign such a covenant, and if not, then have a great time in Sky City! After speaking, he didn't wait for Ryan to react and just raised his feet and left.

Ryan almost didn't hesitate, and hurriedly said, "This covenant will become a witness to history!" My only hope is that this covenant will last for a long time, and we can both grow and develop together! ”

Cao Hong didn't look back, directly pointed to Wang An, who had been looking indifferent next to him, and pushed the door to leave.

Ryan looked over, Wang An raised his head slightly and said, "Then next, we can talk about it specifically!" ”

On the border of Grasse Province, the Empire's armies are constantly coming in, building a checkpoint in a difficult place.

This is one of the two passages for the Northwest Province occupied by Cao Hong to enter the imperial capital, and the other one needs to cross a huge inland sea spanning 800 miles, and there are naturally sea dragon sailors on the water surface to deploy it. That's why the Empire has placed its key defenses here.

The surrounding countries are already ready to move, and Cao Hong, the initiator, will naturally not give up.

Half a month has passed, and the fifth-level white wolf pack has not only been replaced, but the number has also exceeded one million. Coupled with the same number of other auxiliary troops, there is still a good chance of winning against the level with a complete magic defense system.

The dark line of the dark clan is really useful, I don't know how they got it, and they actually transferred the little city lord who ran away without permission before to be the highest commander of the level.

Think about it, what an advantage it is for the enemy to have such an incompetent and incompetent supreme commander.

Sure enough, as soon as this goods arrived, it gave Cao Hong a big surprise.

He directly ordered to abandon the first line of defense that was about to be built, and instead built a large fortress city close to the mountain wall.

All the forces were shrunk into the city, and the city lord's mansion was densely packed with swordsmen and magicians, and it was difficult for even ninth-level masters to break in.

Looking at this posture and thinking with his ass, I also know that he will definitely not be able to shrink like a turtle!

At this point, Cao Hong is actually quite annoying, after all, the white wolf pack is still good at field warfare, and the upgraded white wolf pack, although the power has increased several times, but the battle is still a place where the ruler is short.

Fortunately, Cao Hong had already thought of this situation, and in the past half a month, he has deliberately come up with something new for tackling tough problems.

The Fortress City's magic defense system is of the highest level, and it is said to be called the Simria level, and this twisting name is a demigod-level magician who accidentally entered the tenth level a few decades ago. The empire put his name here, and it may not be without a taste of prayer.

However, Cao Hong will let the facts prove that this is useless.

In the early morning, the sky was just dawning, and the calm morning glow in the distance was shattered by a loud roar. More than five thousand rank five white wolves rushed towards the fortress support at an extremely terrifying speed.

"Enemy attack! Enemy attack! Inform the Castle Lord! Enemy Attack"

The soldier who had been guarding all night, and his eyelids were about to stick to each other suddenly became a spirit, like a black cat that had suddenly stepped on its tail, screaming with its teeth and claws.

Several soldiers next to him were frightened by this sound, and directly pressed a button at the same time, and suddenly all kinds of magic alarms resounded throughout the city! From discovering the enemy situation to issuing the alarm, the process took less than three seconds, which shows how well the fortress alarm system has done, and how afraid the city lord is of death!

Facing the fifth-level white wolves below, the soldiers guarding the city all clenched their weapons in their hands, nervous and scared in their hearts. The horror of this herd, they have heard too much, too much, and the nervous city lord has added fuel and vinegar, and now they subconsciously weaken their legs when they see the white wave.

Soon, the mysterious and mysterious magic textures on the three magic towers that supported the magic defense system all lit up at once, and a little light condensed at the top of the tower, shot out quickly, and converged in the sky. It unfolded to form a circle, constantly swirling, incomparably bright, full of mysterious and beautiful energy magic array.

A white light shot out from that energy magic array, and it sank into the bodies of those soldiers defending the city, and the fear in the hearts of those soldiers defending the city was completely dispelled in an instant, replaced by an incomparably strong will to fight and incomparable courage. I felt that my nose was spewing hot air, and I wanted to jump off the city wall immediately, and use the sword in my hand to cut those hateful and ugly demonic beasts into two pieces.

From the energy magic array, a green magical light shot out, enveloping those soldiers defending the city, and immediately blessed their weapons with armor-piercing magical attributes, and at the same time blessed them with various auxiliary magic such as agility and great strength.

Then, from the energy magic array, a gray magic light shot out, and it was directly thrown at the fifth-level white wolf pack that was galloping outside the city. Those fifth-level white wolves who were illuminated by the gray magic light were immediately covered by weakness spells such as weakness and sluggishness, and their movements suddenly became sluggish.

It looks like I've suddenly grown old to eighty, and even the roar is slow.

Immediately after that, the cannon and crossbow arrows on the city wall fired at the same time, and the original huge crossbow arrows could penetrate five or six white wolves in a row, but they didn't have so much power in the face of the fifth level, and the lucky ones could kill all the time, but whoever let the white wolves dodge a trace did not die immediately.

And those cannons are constantly exploding in the wolves, and the sky is full of smoke and flesh mixed with flesh and blood, and I don't know how many white wolves have been killed.

However, on the huge city wall, there are only 5,000 white wolves attacking the city, and they are naturally scattered among each other, and not every cannon and crossbow arrow can hit those swift insects.

Less than a hundred human crossbow arrows and cannons were killed, and the wolves had already easily penetrated into the city wall with their sharp claws, ran up the city wall, and looked like they were about to pounce on the soldiers.

At this time, in the sky, in those energy magic arrays, red magic light shot out again, and it sank into the city wall, and suddenly a layer of surging magic flames burned on the city wall.

The wall of fire was so hot that it burned the white wolves that crawled all over the walls to ashes almost instantly.

There are sporadic white wolves cooperating with each other, jumping over the wall of fire and jumping directly onto the city wall, but at this time, a huge steel net will suddenly appear, instantly rolling the white wolf into a dumpling, and then more than a dozen human warriors with heavy weapons will jump out, constantly bombarding its head with maces and sledgehammers, until it smashes into a pile of rotten meat.

However, this ambush trap does not always work, and when there are more than two white wolves together, a wave of their claws will cut the steel web in two, along with a human warrior.

But this is on the city wall after all, the place is not very big, and most of it is occupied by the soldiers who defend the city. Even if the white wolf occupied a favorable situation for a while, under the double pressure of the magic defense formation and the frantic siege of the guards, they were still surrounded and killed by humans one by one.

On a small hill thirty kilometers away from here, three thousand rocket launchers loaded with special ammunition have been connected, and the last position signal sent back by the white wolf pack is directly ignited, and the three thousand rocket warheads dyed in a terrifying green sky soar into the air and bombard the city wall directly.

No matter what kind of magical defense system, as long as the wall collapses, it will directly lose its effect.

When the three thousand rocket warheads appeared on the horizon, the energy magic array above the fortress city shone brightly. Ten dazzling magical rays also shot out, quickly staggering in the air, and unexpectedly formed a huge five-pointed star defense array.

Rumble!

The first breaking missile exploded violently, detonating the huge force in it and setting off gusts of wind!

A large amount of green powder burst out and rained down.

The city's city defense magic guide defense system was developed based on the magic of the same world and the attack ability of warriors, and it did not have the ability to remove dust, so when these green powders with no energy at all floated down, it didn't play any role.

Explosions continued one after another, and the entire sky was almost obscured by green powder, and the entire fortress city had a feeling of being pressed by black clouds.

Green powder fell to the ground, on the roofs of houses, on the bodies, faces and armor of the warriors.

A curious soldier stretched out his hand to wipe it, and he heard a series of bubble popping sounds, and then a yellow-green gas floated up in the palm of his hand, and before he could see it clearly, it had already dissipated into the air.

The soldier paused for a moment, then burst out laughing, and exclaimed, "What is the other party doing here?" Could it be that the other party sent it to make us happy? ”

The soldiers were fine, and the guards, who had long been itching for a long time, reached out to grab the green powder, listening to the sound of "popping" while watching the yellow-green smoke dissipate in the air. They all found it funny, looked at each other and laughed.

Suddenly, the soldier at the beginning was suddenly shocked, his eyes blurred, his body began to twitch involuntarily, and he couldn't help but spit out a large amount of white foam in his mouth, and said with difficulty: "Not good! …… Yes...... Poisonous! ”
