Beyond the city, the ground was slightly raised, and a familiar head poked out of it.

The person who came was none other than the powerful enemy who almost killed Sara before, the fifth-order undead bone beast.

He had only recently woken up from his slumber, only to find that the sky had completely changed outside.

The fifth-order undead who were originally wandering around disappeared for some reason.

Even the slightly more advanced third- and fourth-order undead only had two or three kittens and puppies left.

The first reaction of the Bone Beast, which sensed that something was wrong, was to come to the Black Warrior City to investigate the situation.

After seven days of reconnaissance, the Bone Beast finally confirmed something.

That is, Sarah, the king of the Black Knights, is also gone!

This is definitely great news for the Bone Beast, the mortal enemy has disappeared without a trace, and there is no existence of the same level nearby, then this will definitely be his territory!

When the time comes, you will pocket thousands of miles of territory and gather your little brother to collect energy for yourself! The day when he will soar is just around the corner!

Just want to be the boss, there must be a territory, so the bone beast ran over and prepared to grab the territory.

Shaking his body, the Bone Beast suddenly broke through the ground, followed by thousands of cannon fodder subordinates who had worked so hard to collect during this time.

With a sweep of the tail, a huge bone ball shot up into the sky, hitting the wall with a thud.

It's just that the wall that was frantically thickened by Gu Erdan has expanded from the original 3m wide to 6m at this time.

A city wall of this level can resist even cannonballs, let alone a mere bone ball.

Seeing that the walls did not collapse, the Bone Beast was overjoyed instead of angry.

Great place! Absolutely great place! Easy to defend but hard to attack! Defend strongly! It's definitely a good place to dominate!

He's going to settle this place!

rushed up, and a large number of junior brothers rushed to the city wall like a tide.

A new round of siege warfare began at one time.

The crackling sound outside did not attract Gu Erdan's attention, because he thought that these skeleton soldiers were noisy, so he specially ordered someone to strengthen his room, and the sound insulation effect was outrageously strong at this time.

It wasn't until a bone ball fell from the sky and hit the roof with a bang that Gu Erdan was startled.

Stopping to calculate the income of the system's recent energy, Gu Erdan hurried out of the room, shouting while brandishing his spear.

"What's wrong! What's wrong! What bastard would dare to jump on my roof! Don't kill him! Bodyguard! What about the guards! Grab him and hang him on the street lamp! ”

The second general of Humm, who was guarding the door, that is, the Knightless Knight and the Bone Vanguard, hurriedly responded when he heard this.

"Report to Your Majesty, there is an invasion of a strong enemy."

That's right, these two guys can talk, because the two of them are no longer third-order undead, but fourth-order, officially stepping into the level of middle-order undead.

This also made the two of them have further developed their originally low IQ, although they are still stunned and virtuous, but at least they can talk to Gu Erdan.

Not only the two of them, but the undead who had reached the fourth-order level in the castle at this time, not to mention a thousand people.

Because Gu Erdan finally relied on overeating two days ago and successfully broke through to the fourth-order level.

As the so-called one person ascends to heaven, if it weren't for the lack of energy stored in the system, Gu Erdan would be eager to raise all the younger brothers to the fourth level.

Name: Gu Erdan

Identity: Fourth-Order Skeleton Pioneer (inferior)

Skill:

One Ring Spell ~ White Bone Regeneration

Second Ring Spell ~ Primary Bone Enhancement

Three-ring spell ~ death perception

Four-ring spell ~ Phantom Impact

Introduction: Meat shield type high-grade cannon fodder, you deserve it.

The two newly acquired spells are not very effective.

Death Sense is a recon spell that predicts an impending threat.

If you perform this technique as a living creature, it will only last for about ten minutes to an hour.

But Gu Erdan is different, because this is the reason for his natural necromancy, it has directly become a passive ability, which is turned on 24 hours a day, just like a primary bone enhancement.

As for the four-ring spell Phantom Impact? The effect of this trick is very simple and crude.

Speed up, rush at him! Directly mobilize energy to increase your speed! Gu Erdan can even make his speed skyrocket to the level of an F11 formula car in a short period of time!

It's a pity that the steering is a little difficult, and I always like to hit the wall, and yesterday the front teeth of the skull's head were knocked off several times.

By the way, this skull has also been strengthened to the fourth order by Gu Erdan, and I don't know if it's because of the benefits, the skull that originally played with Gu Erdan at every turn suddenly stopped, even if he was knocked out of his front teeth yesterday, he didn't choose to get angry with Gu Erdan.

This made Gu Erdan feel a little uncomfortable.

This enemy is suddenly so honest, and he looks like he is fighting and resentful, so how can he be embarrassed to take it out to block the knife in the future?

No way! You have to find a way to stimulate him!

The whistling wind suddenly sounded, and Gu Erdan, who learned that there was a strong enemy invasion, didn't wait to ask, but before he could ask, he saw a huge bone ball slashing from above, hitting the wall with precision.

Looking at such a familiar attack method, Gu Erdan was silent for a second, and then the soul ghost fire in his eyes was flourishing.

"I'll go! Isn't this an attack from the Bone Beast! That grandson is back! Tell the little brothers to catch me alive! There is hope for Lao Tzu's mount! ”

Suddenly pushing away the second general, Gu Erdan ran excitedly towards the direction of the battlefield, and the scene of himself riding the bone beast across the battlefield already appeared in his mind.

However............

When Gu Erdan worked hard to cross the four city gates and ran into the battlefield, he found that he was too late.

The poor bone beast was lying on its back to this side, half-lying on the wall, as if trying to escape.

But he never had that chance again.

Because this guy's skull has been smashed open, and the soul fire has also been taken away, and he has completely hung up, and his body is dead on the spot.

Looking at the huge undead corpse in front of him, Gu Erdan's body trembled wildly.

"Who! Who did this to you! Can't you slow down! ”

The leader of the black warrior squad, who was holding the soul ghost fire and trying to show it, stiffened when he heard this, and threw the ghost fire on the ground without hesitation, and then began to look left and right, looking like he was looking for the culprit.

With the upgrade to the fourth order, the IQ of this group of guys is getting higher and higher, and they not only learn to speak, but also begin to learn to play tricks.

For example, if it is a low-level undead, it will definitely swallow it and take it for itself without hesitation.

But this group of fourth-order subordinates is different, they have brains, they know how to analyze, and they also found that Gu Erdan can make them evolve for no reason.

I even remembered the scene where my former boss, Sara, became the Lord of the Undead.

Compared with each other, this originally alluring fifth-order undead ghost fire suddenly lost its allure and didn't seem to be so fragrant.

Looking at the many younger brothers who distanced themselves from the undead ghost fire like a plague god, Gu Erdan knelt on the ground with a plop, holding the flame and crying.

"Finally, a mount came! You don't think about how to catch them alive! But he only thinks about killing him and eating meat! Shall I send you this bite?" You guys...... Belch...... You guys are going too far! ”

While stuffing the soul ghost fire into his body, Gu Erdan complained loudly, and the little brothers around him looked at me, I looked at you, and finally after the chaos, one of the weakest unlucky eggs was pushed out and became the person in charge of the back pot this time.

A few minutes later, under the huge banner planted on the city wall, hung an unlucky skeleton soldier, waving in the wind.

And under the flag, Gu Erdan looked into the distance with a haggard face, and at his feet, there was a foal no more than half a meter tall.

This is his current mount, codenamed Chasing the Wind.

A fourth-order foal, a very strong foal, a foal that anyone dares to bite except Gu Erdan.

Even this one got himself a horse armor, which looked very majestic.

But the problem is that he's only half a meter tall!

Wear women's armor! Ride a half-meter high foal! Is this called the Headless Horseman? It's called a neurotic disease!

Gu Erdan only felt like crying without tears at this time.
