Having made the decision, Su Ziyu acted decisively.

He simply stopped the construction of the entire base camp and summoned all his vassal races.

The succubus lieutenant led a demon army to the east to harvest. There were some wild demons that Suzi had released there, as well as a small number of abyssal worms. At first, he planned to slowly release them for a while. The wind element in the north was directly sent by Claire to lead the fire demon to push forward. As long as the benefits were greater than the cost, it was worth it.

"Owner!"

The snake demon transformed from the soul of the nine-headed lizard was directly promoted by Su Ziyu to a six-armed snake demon. Just as expected, she was also an elite unit after the promotion.

The biggest difference is that she has mastered Advanced Multi-Attack and Advanced Multi-Weapon Combat.

Su Ziyu has not yet developed to his limit. If he continues to upgrade the Abyss Blood Pool, he can advance to become a Demon Lord. At the same time, the demon can also awaken the memory of the previous life to gain some professional ability blessings, such as the Barlow Flame Demon Beheader, which is obviously a very powerful advancement.

But the problem is that as the fish grow, so do the devils.

At the current stage, he clearly has the advantage. The number of demons is huge and they multiply very quickly. Relying on his numerical advantage, he can suppress the demons.

If he could gain a large amount of killing power and demon genes by killing demons.

So can the devil also be promoted after killing demons?

There is information about the bloody battle in the abyss in Tower Ling No. 76.

In this endless bloody battle between demons and devils, each time a large number of demons faced a smaller number of devil elites, but ultimately ended in failure.

Su Ziyu discovered a problem.

That is, when the advantage of numbers cannot be brought into play, will the huge army of demons give the devils more experience in the bloody battle in the abyss?

Otherwise, why are there so many high-level beings among the demons?

From the perspective of quantity, Su Ziyu's demon army is more than five times the size of the devil's army, but judging from the quality, the devil's army has obviously more advanced units, and their development path is obviously high-quality troops.

Therein lies the key.

The devil is now building a steel fortress. If this steel fortress is completed, will Su Ziyu attack or not?

If we don't attack, the power of the devil will continue to grow. If we attack, the losses in a siege will be staggering.

The final result may be that the devil gains more!

The current situation reminded Su Ziyu of a strategy game he had played on Earth. The demons were like barbarians. It was easy for them to recruit troops, but they had no technology. The devil was like the Roman Empire. As long as it was given time to develop, and had enough weapons and equipment and technology, and could deploy its reformed first-class troops, it would be completely beaten in all kinds of ways. There were many ways to win with fewer troops.

The devil is an undisciplined army.

This is the most fatal problem!

When the number of demons expands to a certain extent, the lack of discipline will become an extremely fatal weakness.

With the current number of demons, Su Ziyu is having a hard time commanding them in battle. What if the number of demons swells to hundreds of thousands?

In a large-scale battle.

The advantage in numbers is not that great, because there are only so many people who can face off on the battlefield. Su Ziyu put himself in their shoes and found that he only needed one-tenth of the elite devils to easily rely on the steel fortress to defend against an army of demons that is ten times larger than his.

As you kill demons and advance to the devil elite, the balance of victory will soon tip in your favor.

Than construction?

Su Ziyu looked at his base camp which was still in a mess.

Compared with technology?

Su Ziyu looked at his blacksmith shop which relied entirely on the fire giant to operate normally.

This is still the late stage of the fight.

Go for it!

The devils were almost building a steel fortress, but they didn't even have a decent wall. Su Ziyu could imagine what the situation would be like in the later stage.

Fortress of Bones.

Su Ziyu brought his men directly to visit the lich here. He also brought the spoils of the fire giant tribe. As long as it was something that he could not use temporarily, he was ready to trade for souls.

"Owner."

"Those demons are here again!" The ghost floated in a bit panic.

soon.

Su Ziyu saw the lich again, but this time he was wearing a monocle on his head.

"What do you want from me all of a sudden?" the lich asked with a strange expression.

Su Ziyu waved his hand to signal the demons to carry the things up, a large amount of gold, jewelry, ore, and some things he didn't know what they were used for.

There are very few undead in the burial grounds anymore.

Su Ziyu, determined not to make the trip in vain, killed the wandering undead along the way, gaining a total of about a thousand soul points.

"We found traces of the devil." Su Ziyu thought for a moment and said, "We need some souls. I hope to buy them from you with these things."

devil?

Why are there still demons in this dimension?

The lich quickly confirmed that the demon lord in front of him was not lying, and then he thought of a war that had long been forgotten in his memory.

——"Blood Battle in the Abyss!"

Demons and devils are the mortal enemies of the lower planes.

Basically, they would start fighting as soon as they met, and sometimes they would bring their respective helpers. The undead would sometimes appear on the battlefield of the bloody battle in the abyss.

No wonder the demon lord in front of him is so excited, does he want to fight a bloody battle with the devil?

Do you need help?

The lich looked at the pile of treasures in front of him. These things were just materials to him. The lich had no hobby of collecting gold and jewelry.

Maybe it could help, all they wanted was some souls anyway.

The lich quickly realized that the strength of these demons had expanded too much, so it was a good opportunity to let them fight a bloody battle with the devil to consume their strength. As long as more demons died, he would not have to worry about the demon lord in front of him threatening the safety of the Skeleton Fortress.

"Please come in." Thinking of this, a creepy smile appeared on the face of the lich in front of him.

That's right.

Let these demons fight the devils!

It's better to end up hurting both sides.

As a lich, he has a lot of soul reserves. He will definitely not trade high-quality souls, but some inferior souls can be traded to these demons.

The Summoning Tower can often capture the souls of some goblin kobolds, and many of these creatures' souls flow into the lower planes every year.

Liches use them to fill the boneyard, because these fragile souls are only enough to resurrect skeletons. Only souls at least at human level are qualified to be transformed into ghosts.
