After Cheng Yang came out of the Tower of Souls, he did not directly attack the surrounding undead, but brought the black warrior who only had his torso left and used the soul extraction secret technique on it.

As a wisp of soul entered Cheng Yang's mind, the memory of the black warrior was also copied by Cheng Yang. But something that shocked Cheng Yang was what happened, after the black warrior was extracted a trace of his soul, the soul fire in the entire black skull directly dissipated.

Cheng Yang couldn't explain this matter, originally he thought that this was a special case of this black warrior individual, but then he caught a weak undead and used soul extraction again, and the other party also hung up.

This illustrates the fact that the Soul Extraction skill is not a panacea, and it may only be effective against the living race, but not the undead by extracting souls.

As for the deep-seated reason for this, Cheng Yang doesn't know, maybe the gods can know all this.

It's not that Cheng Yang didn't get nothing, and the black warrior's huge memories contained too many things, including things about the so-called rituals in the black warrior's mouth.

"This undead clan is really ruthless, and they are willing to use tens of millions of undead to accompany the burial for this ceremony!" Cheng Yang's expression was extremely serious, but what made him quite entangled was that he had not found more information about the ritual from the black warrior's memory, especially what the ultimate purpose of this ritual was.

I have to say that the secrecy of this undead clan is indeed very good, and even the high-level undead such as the peak of the fifth order don't even know what the ultimate purpose of this ritual is, so you can imagine how cautious the undead emperor is.

This ritual is indeed extraordinary, in addition to the burial of tens of millions of undead, it also requires the blood of tens of millions of living beings. And to perform this ritual, it must be presided over by nine undead masters above the sixth order.

If such a ritual is not enough to defy the sky, Cheng Yang doesn't know what kind of ritual is powerful.

Now. Cheng Yang finally understood why the undead clan did not send a master to directly break through the defense line of the American Alliance, they wanted to create a huge battlefield in the Panama Canal, a meat grinder-style battlefield.

Obviously, the undead have done it, and they have always controlled the rhythm of the war, so that the human side is constantly throwing troops over. At the same time, it is constantly consumed on the battlefield.

And the same is true for the undead clan, but they don't send real masters to participate, all of them are skeleton soldiers in the early stage of the third order equivalent to cannon fodder troops, and occasionally send a fourth-order undead army, which is also sitting, once they are frantically blocked by the other party, these elites will immediately retreat.

What makes Cheng Yang frightened is that now the casualties on both sides of the battlefield have reached millions, and I am afraid that it is not far from completing the ceremony.

Cheng Yang's idea just came to mind. I saw that thick dark clouds suddenly appeared in the sky, covering the sky and the sun, covering all the dozens of kilometers in it.

Wisps of black aura continued to emerge from the ground, blending into the dark clouds in the air.

"What's going on?" Cheng Yang was suddenly shocked, this was obviously not a change in the natural climate, "Is it so coincidental?" Just in time the ritual of the dead is completed? ”

Cheng Yang naturally didn't know that the undead clan had already completed 99% of the prerequisites for the ritual in the previous battle. It's just that the soul energy of the undead is slightly insufficient.

In that short period of time, the Demon Illusion and a group of archers killed a large number of undead masters. The souls of these undead masters were definitely worth hundreds of thousands of ordinary undead, so they instantly made up for the part of the soul energy that the ritual lacked.

"Lord, the situation is not good!" Xu Wu quickly rushed to Cheng Yang's side, as a territorial guard from another world, Xu Wu's insight was definitely much stronger than that of the person again.

Cheng Yang immediately asked, "Do you know what's going on?" ”

Xu Wu said: "This seems to be the super secret technique of the undead clan, the Death Territory. ”

"What is the Realm of Death?" Cheng Yang was even more confused when he heard it.

Just as the two of them were talking. The black aura on the ground had gradually thinned out, and it seemed to have all melted into the dark clouds in the air.

"Lord, let's retreat first, or it'll be too late." Xu Wu shouted, his face extremely anxious. It seems to have seen something extremely terrifying.

"Okay, you guys get out first!" Cheng Yang made a decision immediately, he believed that Xu Wu would not be able to lie to him at such a time.

The surrounding undead also saw the changes around them, and a roar from the soul resounded through the heavens and the earth, as if celebrating this historical moment.

When all the archers heard Cheng Yang's command, they didn't dare to hesitate at all, quickly jumped into the teleportation array, and quickly disappeared from the spot.

When the last archer left, Cheng Yang immediately put away the teleportation array disk, and then used the Returning Yuan Technique to offset the side effects of the ablation skill on the body, and then the body liquefied and merged into the ground.

Less than a few seconds after Cheng Yang disappeared, the black aura on the ground completely disappeared, and the dark clouds in the sky had completely turned pitch black, and they were much bigger than before.

Immediately afterwards, the dark clouds began to surge, and bursts of black rain fell from the sky, and the black raindrops on the ground actually corroded the soil and stones on the ground, and the soil quickly turned black, and the stones turned into shatters on the spot.

As for the original dead trees and plants on the ground, they were reduced to ashes.

But on the contrary, it was the undead who were glued to their bodies by the black rain, and the black rain did not corrode them in the slightest, but instead merged into their bones, making their entire bodies more powerful and strong.

What's even more strange is that these black rains landed in the area south of the Yellow Spring River, and not even a drop of black rain fell on the stone beam.

Then, the black clouds in the sky slowly became larger and swept towards the south, and the black rain also fell on every corner of the southern land, and the whole land was changed, and even some mountains were directly flattened because of the corrosion of the black rain.

As the black rain fell, a black mist slowly emerged from the pitch-black ground, condensing within hundreds of meters above the ground, and showing a tendency to become thicker and thicker.

Cheng Yang continued to hide below the ground at the moment, the super corrosive black rain did not affect him much, but the changes in front of him brought an extremely strong shock to his heart.

This can no longer be described by magic, he can see clearly, according to the posture of the black cloud in the sky, it is estimated that it will not corrode all the thousands of kilometers in a radius, and it will not stop at all.

It's just that Cheng Yang can't understand that since the power of this black fog is so powerful, why does it only fall south of the Yellow Spring River? If this rain had fallen on the human side for a few minutes, the fortress on the opposite side would not have to be beaten at all, and all the people inside would have turned into dry bones.

If you don't understand Cheng Yang, don't think about it, the undead are not continuing to attack the city at this moment, and the dark clouds in the air have already drifted dozens of kilometers away, so there is no need for him to continue to stay here.

Cheng Yang crossed the Yellow Spring River and returned to his own station.

At this moment, the barracks here have been erected, but the soldiers did not stay in the barracks, but nervously lined up for battle, as if a big war was coming.

Cheng Yang knew that the reason why they were so nervous now was just because of the strange phenomenon just now, and for most ordinary fighters, the scene just now was indeed too terrifying.

"Lord, you're back." Xu Wu saw Cheng Yang appear in front of him, and his originally nervous expression suddenly dissipated a lot.

Cheng Yang smiled and said, "You also underestimate me too much, right?" With this little raindrop, you can leave me behind? ”

Xu Wu smiled bitterly and said, "Lord, you don't know, that death territory is definitely a forbidden level secret technique of the undead clan, and even ordinary gods can't perform it alone." It is simply a catastrophe for living species. ”

"Tell me what the Realm of Death is." Cheng Yang asked.

Xu Wu said at this time: "My subordinates also saw in a collection of books in the clan before, in the space where the undead clan lived, the ground was full of black soil soaked in dead air, without the slightest anger, and even the air was filled with a thick dead air. Even if a living person arrives in the world where the undead live, they will be soaked into a living corpse by the breath of death in a few days. When a new land is occupied by the undead, the undead will perform this sacrificial ritual called the realm of the undead, using the souls of countless living beings and the dead energy of the undead to transform the newly occupied world into a world suitable for the undead. ”

"You mean that the undead are planning to turn all of South America to death?" Cheng Yang's face suddenly changed greatly, if this is the case, I am afraid that even if the human race takes back South America in the future, I am afraid it will be meaningless.

Xu Wu nodded and said, "That's true." ”

"But what good does this do for the undead? Why are they in such a hurry to transform South America? The doubts in Cheng Yang's heart were not solved.

Xu Wu said: "The Death Territory naturally has great benefits to the undead, first of all, the undead can exert stronger combat power in the Death Territory, secondly, the death qi in the Death Territory can make the undead evolve faster, and finally, and most importantly, once the Death Territory appears in one world, then the soul power of the people in this world after death will naturally gather into the Death Territory, and finally give birth to new undead." This kind of undead spirit has a strong immediacy, and it can only be the lowest-level skeleton soldier, or it can be the most powerful race of the undead race, the bone dragon. A fully formed bone dragon with at least the strength of the late sixth order, which would be of incomparable value to the entire undead clan. ”

Cheng Yang was shocked after hearing this, and said, "How can you directly give birth to a sixth-order existence?" Isn't that too rebellious? How could the gods allow such a rule to exist? ”

Xu Wu said with a wry smile: "I only saw it from ancient books, and I can't be sure if it's so." However, even if it is not possible to directly breed a sixth-order existence, just the combat power bonus and evolution speed bonus of the Death Territory to the undead are enough for the undead to venture to activate this ritual.
