The tragic battle continued, and the first line of defense did not last long, and was blasted open a gap by a giant corpse with a height of more than 7m, and it was completely lost.

Then came the second line of defense, which he had broken through by the giant stitched corpse.

Originally, Gu Erdan thought that as he became a bone frame, his mental endurance was already very good.

But after seeing this giant stitched corpse demon, Gu Erdan still had some unbearable feelings.

Hands and feet of humans and animals can be seen everywhere, some of them are weak to hang down, and some of them are still able to swing and attack.

And there are also a large number of skulls mixed in it, which is terrifying!

In fact, this is not the most terrifying place to stitch the corpse demon, because this place is the undead realm, and no living creature can survive here, which also causes the parts of the corpse demon to die.

If it were a human being, many of the corpses that he sewed up to his body would still be alive, and they would be tortured all the time, constantly screaming.

It was a purgatory on earth! It's enough to break down anyone who isn't firm in mind!

It is precisely because of this cruel method that the necromancer will become a street rat that everyone shouts and beats.

The first line of defense and the second line of defense were broken one after another, and the next two lines of defense did not last long.

Seeing a large number of enemies pouring into the middle position, Sara suddenly raised her hand and waved, and the black warriors behind her, who were already ready to attack, began to move along the road above the city wall.

Don't look at those giant dried corpses and stitched corpses that look scary, but their strength is actually just like that.

It's nothing more than relying on the strong and strong people to be tall and big, barely squeezing into the fourth class, if they really face the black warriors, a team of 20 people is enough to hunt them down.

The reason why these guys were able to break through to the fifth layer of defense as if nothing was purely because Sara deliberately let them do this, in order to catch a turtle in the urn.

The defenders on the previous four lines of defense, let alone the black knights, did not even have skeleton soldiers over the second order, they were purely a group of cannon fodder.

Their task is to die, and by the way, to serve some delaying effect, in order to divide the enemy.

It was only when the enemy rushed into the middle position that the true defensive system of the castle was fully revealed.

The motionless catapults on the city walls are moving! Skeletons began to carry stones and throw them at the breach.

As for the Black Knights, these armored creatures have already begun to stand on the walls of the city and target them.

More than a dozen javelins fell together, and even if a fourth-order existence was targeted, it would be either dead or injured, and the third-order enemy would die violently on the spot.

They are only responsible for killing high-level undead, and as for those who are first-order or second-order, the black knights don't care.

This group of enemies with poor strength, seeing the strong people around them fall to the ground one after another, instead of choosing to flee and retreat, they rushed madly towards these corpses, desperately tearing the soul flames into their stomachs, and some even fought for it.

The army of the undead, who were still rushing forward without a brain just now, fell into chaos in the blink of an eye, and completely stopped in front of the fifth city wall.

The walls on both sides were full of black warriors, javelins raining down, and the corpses below the beatings were spread layer after layer.

And under such terrifying firepower, the undead who were frantically snatching the soul ghost fire below were still fighting each other, not thinking about whether they could have a chance to get out alive.

With such a scene, Gu Erdan, who watched it, shook his head.

Sure enough, all diseases can be saved, but there is no cure for brain damage.

The siege lasted for several hours, and it was not until it was getting dark that the battle was completely over.

At the end of the fight, some of the smarter undead tried to escape in vain, but it was a pity that the black warriors lined up a gap, which directly made them unable to escape.

Halfway through, Gu Erdan and the others also encountered a special situation, that is, there were some flying undead who tried to fall from the sky and forcibly snatch the loot from the flag.

It's a pity that he was shot down by a round of javelins from the black knights who had been prepared for a long time.

This kind of offensive and defensive battle, Sara is obviously not the first time they have experienced it, and they have already played experience.

Air defense, blockade, hunting, the black warriors have a clear division of labor, and do not give the enemy a chance.

With the end of the siege, instead of losing any high-level soul ghost fires, Sara's side also captured six fourth-order soul ghost fires, twenty-seven third-order soul fires, and countless other ghost fires.

After sweeping away all the enemies, Sara immediately devoured a fourth-order ghost fire, and then hesitated slightly, and actually gave Gu Erdan one, which made him flattered, and he was actually a little stunned for a while.

Sara didn't pay attention to the stunned Gu Erdan, but came to the undead corpses piled up, took out the strong undead corpses that had been sorted, and began to make subordinates.

The third-order soul ghost fire in his hand slowly dispersed, turning into black flames and enveloping the corpse's whole body, accompanied by the three-ring undead spell ~ the black warrior resurrection technique, the corpse lying motionless on the ground began to tremble slightly.

The flesh twisted and shriveled, and the white bones placed around it continued to wriggle, gradually enveloping the corpse.

By the time the spell was cast, the corpse on the ground had changed dramatically, turning into a black warrior with a human silhouette, heavy black armor, and a blood-red rose totem tattooed on his chest.

Seeing that Sara spent a lot of effort to use up all the hard-won more than twenty third-order soul ghost fires, all of which were used to create black warriors, Gu Erdan was a little confused.

It's good to have a strong underbelly, but not more is better.

The area of this city is limited, and more than a thousand black knights are enough, so why should Sara increase her subordinates?

If you don't understand, just ask, Gu Erdan didn't choose to hide it.

Faced with Gu Erdan's inquiry, Sara answered very simply.

These black warriors, he will use them in the future, so there must be more of them.

The first day of the offensive and defensive battle passed like this, and the night was silent, and with the black sun rising on the second day, a new round of war began.

Or as always, the flag is raised, and the ghost fire lures.

As always, the army attacked, entering the city to besiege and kill.

The battle lasted for a week, with all sorts of accidents happening during the process.

After all, the undead have a variety of spells, some of which are extremely powerful, and some of them can even pose a threat to the black warriors.

Faced with such a situation, Sara will always be the first to strike and suppress the enemy with his strong strength.

Seven days passed, and on the eighth day, the Black Warrior City chose to suspend its death, and instead began to go to the canyon to gather skeleton soldiers and heal the wounds of his wounded men.

In the casual conversation, Gu Erdan also understood the special features of this canyon.

A large number of skeletons are revived every seven days, and these skeletons are so violent that they can't be recovered.

Sara didn't know what was going on here, all he knew was that the canyon had been like this since he came here.

Even Sarah's choice to build her castle here is a big reason why this eerie canyon is a big reason.

With a treasure land that can provide a large amount of soul ghost fire on a regular basis, Sara will certainly not let it go, not to mention that the terrain here is steep, easy to defend and difficult to attack, and it is indeed a good place to defend.

It's just that everyone likes the treasure land, because of this canyon, Sara is not in trouble, and the reason why so many black warriors were injured a few days ago is because of the invasion of strong enemies.

And those strong enemies are not completely rushing to this canyon.
