You know, even a LV25 undead mastered three-headed hell thunder dragon plus dark gold-level skills can only increase the undead's strength to 30% of its original strength.

The strength of the ordinary necromancer who is less than LV10 is even weaker.

Generally speaking, any spirit that can exert one tenth of its strength in life is considered extremely powerful.

Of course, the undead level of the three-headed hell thunder dragon has been suppressed. If the real three-headed hell thunder dragon descends, it is estimated that the undead level will not only be LV25, but the level of the sea of ​​the dead will definitely be full.

At the same time, the number of undead he could summon was definitely countless times more than what Ling Yan had seen at the beginning.

After all, the strength of an emperor-level BOSS during his lifetime must have reached at least LV700!

At the same time, they were able to kill the Holy Dragon of Light, which was also an emperor-level BOSS and still had life force. It can be imagined that the strength of these three Hell Thunder Dragons was absolutely terrifying.

It’s a pity that because he was projected by the will of Apocalypse, the strength he could exert was only that of an ordinary top-level emperor-level BOSS.

And there is one more important point.

That is, the residual soul can become an undead as long as it is refined.

But the residual soul is very difficult to explode.

You have to kill tens of thousands of wild monsters to get the soul of an ordinary monster.

Only after killing tens of thousands of elites can an elite remnant soul be revealed.

By analogy, it takes killing tens of thousands of Emperor-level BOSSes to reveal the residual soul of one Emperor-level BOSS.

Therefore, the value of this residual soul is extremely powerful.

Ordinary all-spiritual wizards simply cannot obtain so many residual souls to form the Sea of the Dead.

However, at this moment, these shortcomings seemed to have disappeared from Ling Yan's body.

Looking at the overwhelming number of LV100 demons, which numbered at least ten trillion, Su Miaoran was completely stunned.

And she opened up one of the attributes of the demon, wow!

It is twice as powerful as an ordinary LV100 wild monster!

And these densely packed tens of trillions of heads spread out madly in all directions. The number was so terrifying that Su Miaoran couldn't help swallowing his saliva.

"roar!!!"

"roar!!!"

…………

However, at this moment, roars louder than ordinary roars rushed out from the gate of hell.

The next moment, hundreds of millions of elite-level, tens of millions of leader-level, and hundreds of thousands of king-level dark spirit ghosts rushed out from the gates of hell.

The moment these powerful BOSS-level dark spirits appeared, the surrounding sky and earth became even darker. At this moment, the land within a radius of thousands of kilometers was shrouded in endless darkness, and there was no trace of light at all.

Moreover, as more and more dark spirits and ghosts emerged, the darkness became more and more terrifying.

"My Lord, you have finally summoned me to wait!"

"Hahahaha, kill, kill, kill! This emperor will kill everyone!"

"If the immortal path collapses, then we'll fight our way out!"

………………

At this moment, cold and wild laughter emerged from the gate of hell.

The next moment, ten terrifying figures with the aura of an emperor descending rushed out from the gate of hell.

Behind them were 180 sword immortals with flaming auras surging all over their bodies!

The moment these powerful men appeared, Su Miaoran was shocked.

From the moment the dark spirit ghosts appeared, she roughly guessed where Ling Yan got so many dark spirit ghosts from.

However, when she saw the ultimate boss of these chaotic ghost realms appear, she understood.

Ling Yan must have killed countless people in the entire chaotic ghost realm.

However, even if you kill the Chaos Ghost Domain many times, it is impossible to get so many emperor-level undead.

Ten emperor-level undead, does that mean Ling Yan has killed that emperor-level BOSS millions of times?

Impossible, absolutely impossible. This is probably the maximum number of residual souls of the Chaos Ghost Emperor that have ever erupted from the entire human race, right?

"Oh right, Ling Yan has so much money, he must have bought all the Ghost Emperor's residual souls in the entire human race's resource library!"

Suddenly, Su Miaoran thought of this possibility.

Yes, otherwise where would Ling Yan get so many residual souls?

The money Ling Yan obtained at the time was at least hundreds of thousands of star sources, which was enough to buy so many residual souls.

"Kill all the fire demons you see, leaving no one alive!"

Ling Yan also gave his order directly.

"We obey your orders!!"

…………

All the Chaos Ghost Emperors saluted respectfully when they heard Ling Yan's words. The next moment, these Chaos Ghost Emperors instantly turned into ten streams of light and spread out in all directions.

As for why he didn't summon the fire demon, after all, Su Miaoran was by his side. If he summoned it, his strength would be exposed.

Moreover, there is a helpless point about the undead, that is, although he cannot upgrade with Ling Yan's level, he will be downgraded because of Ling Yan's level.

That is to say, when a LV150 Fire Demon Undead is summoned, its level will be suppressed to LV100!

Although they are more powerful than ordinary elite monsters due to their many passive abilities, compared to the 36 trillion dark spirit ghosts, the more than 100 million fire demon undeads can't make any waves at all.

It would be better to wait until Su Miaoran’s reincarnation mission is completed and then do it alone.

"Let's go, there are dark spirit ghosts here, so we don't need to kill monsters!

I'll take you to do the task first!"

Ling Yan smiled slightly as he watched the black fog expand in all directions.

Then it soared into the sky and flew rapidly towards a relatively large demon city.

"Wait for me!"

Su Miaoran came to her senses and found that Ling Yan had already flown away, so she could only hurriedly chase after him.

…………

Along the way, Ling Yan could hear a prompt sound from time to time.

At the same time, after flying a certain distance, he will use the Sea of ​​Undead again to summon the Gate of Hell.

Those dark spirits who died from killing the fire demons were also resurrected instantly.

Therefore, Ling Yan's monster-killing speed did not decrease.

According to Ling Yan's current experience value, if he is allowed to upgrade, he will probably be able to soar all the way to LV160.
