A wall has been built around the abyss blood pool.

Su Ziyu slightly expanded the number of ants and scarabs, and then left the succubus lieutenant in the base camp and asked her to lead people to build some houses.

Demons are very easy to feed.

They don't need housing, and they don't even need food. They seem to be blessed by being near the abyss blood pool, and they can absorb some energy themselves, and they can even survive by eating dirt. The environment where demons live is quite harsh, and the amount of food is very scarce, but the number of demons has always been large. Their existence goes against the common sense of the ecological chain.

However, mid- and high-level demons also have their own needs.

For example, Berserkers need a training ground where they can fight other demons every day to vent their violent tendencies. Snakes need weapons and shelter, and they are more particular than other demons. At the same time, snakes are also one of the few demons that are interested in jewelry.

As for what the succubus needs, never mind, there is no need to say more about it. There is only one succubus at the moment anyway.

There is no need to consider the needs of low-level demons.

You can just mark out a circle anywhere as a military camp and lock them up inside obediently. There is no need to worry about them rebelling or causing trouble.

At most, the Claw Demon would bully the little devil for no reason.

A berserker will only fight with a strong opponent. A berserker will fight with its own kind if nothing happens, but it will recover after a short rest.

Kobolds are now the main force in mining and blacksmithing.

There are already more than twenty gnolls in the territory. It’s not that Su Ziyu doesn’t want to continue expanding the scale, but because those gnolls have become alert.

That afternoon.

Su Ziyu led his demon army towards the lich's territory. On the way, he saw those wind elements again, but after thinking about it, he decided not to take action. It was too troublesome to deal with flying enemies.

soon.

A towering soul-summoning tower made of countless bones appeared before his eyes.

Click, click.

As if they had sensed the coming of the devil, thousands of undead souls were gradually reviving. Most of them were skeletons, and they seemed to wake up automatically when a living person approached.

"Attack!" Su Ziyu waved his hand.

The demons immediately swarmed over. To deal with these undead, they had to tear them into pieces. Because their numbers were too large, two or three hundred demons rushed in without even a splash. Instead, they were surrounded by countless undead.

——"Flame Field!"

Su Ziyu quickly activated his own fire field, and then saw the skeletons around him gradually collapse under the cover of flames.

"Gain 1 killing power."

"Gain 1 soul point."

"Gain 5 points of killing power."

"Gain 12 points of killing power."

"Gain 1 soul point."

A large number of continuous data prompts jumped out. Su Ziyu and his army of demons had just fought with the undead and gained a full 50 points of soul value.

However, the killing power provided by the undead is very little, with a skeleton having less than 10 points of killing power on average.

Many little demons were killed.

Some of these skeletons were armed, and there were some skeleton archers. The imps and claw demons died quickly, but the mid-level demons did not suffer any casualties. The two snake demons were like killing machines, leaving broken bones wherever they passed. The ability of multiple attacks and multi-weapon combat was quite effective when facing this kind of human wave tactics.

Of course, Su Ziyu is still the most efficient in dealing with enemies.

He only had to walk around with the power of the fire field to kill a lot of skeletons, and then he would add a fireball or a flame storm, killing hundreds of them in the blink of an eye.

at the same time.

Just as Su Ziyu led the demon army to attack the burial ground, a ghost quickly flew into a bone fortress standing in the mountains.

"Master!" "Demons have invaded our land." The ghost flew in in panic.

Inside a huge laboratory.

The table was filled with bottles and jars filled with all kinds of strange flesh and blood. In front of it was a giant dragon skeleton that was sixteen meters long and had a wingspan of about twelve meters. A lich in a tattered gray robe was fiddling with something. Hearing this, he raised his head, pushed his monocle and said, "Demon?"

This lich looks like a scholar and speaks in an orderly and slow manner.

"Oh, right." The lich touched his skull and suddenly realized, "When Bird came last time, he mentioned that a demon lord appeared nearby."

"They're coming up? How many of them are there?"

Once a demon lord appears, he likes to expand his territory everywhere, and the lich seems to have anticipated this.

"Two or three hundred?" The ghost thought for a moment and whispered, "About half of them are dead. They are still in the burial ground. I'm worried that they will destroy the summoning tower."

The lich's jawbone seemed to move, as if he was laughing, and he shook his head and said, "Let me know when they get to the Fortress of Bones."

"My experiment is more important."

The number of two or three hundred is really nothing to the undead.

Rogue is a lich with aspirations. Unlike other liches who spend their days in the tomb, he has his own ideal, which is to advance to become a powerful demigod lich.

But the power of divinity is so mysterious.

He couldn't obtain divinity for the time being, nor could he defeat those beings related to gods, so he could only change his target and try to transform himself into a dragon lich. There had been successful examples of this in the past.

Rogge had just obtained the dragon soul, so he didn't want to bother with those demons now.

He built a soul-summoning tower at the burial ground. The tower would automatically collect the soul power scattered in the wilderness. When an enemy invaded, it would awaken the undead there. These few demons alone might not be able to break through his first line of defense, so there was no need to rush to deal with them.

"Yes." The ghost in front of him calmed down a lot and soon floated away.

The other side.

Su Ziyu led the demon army to kill thousands of undead. Considering that the lich had not appeared and a lot of cannon fodder had died, in order to avoid casualties among the main demons, he simply led his men out of the Skeleton Sea again.

Once you leave the burial ground, the undead don't seem to chase you.

Su Ziyu discovered that some of the undead that had just been killed seemed to have been resurrected, as if the summoning tower had resurrected them.

"Huh?"

"Can I spawn monsters here?" Su Ziyu's expression suddenly showed a little surprise.

A lot of little demons died.

Many claw demons also died.

None of the berserkers were killed, but almost every one of them was injured. The other demons were also slightly injured. After all, the number of enemies was too large.

Let’s go back and rest first.

Su Ziyu had made great gains today. His killing power was close to 20,000 points, and his soul value was 1,200. He could go back to the base and blast another wave of soldiers.

Fortress of Bones.

The ghost floated in again and said cautiously: "Master! Those demons seem to have retreated!"

"Can't even pass the burial ground?" The lich in front of him raised his head and said with a lack of interest: "Got it. Don't bother me when they show up in the future."

"I have set up a withering circle outside the Skeleton Fortress. If the demons get close, activate it."

"Go out."
