The value of Cheng Yang's Void Secret Crossing Technique is vividly reflected at this moment, if other people walk in South America, they will definitely be affected by the ubiquitous dead qi, even if Cheng Yang's strength is strong, he will not be able to stand it for a long time.

But because Cheng Yang was in the void, this void was completely controlled by Cheng Yang, and the dead qi naturally couldn't come in, which also made him not affected by the dead qi.

The only thing that makes Cheng Yang entangled is the efficiency of the search, South America is too large, and it is not so easy to find the undead master from it.

No, Cheng Yang is not without a way, his soul extraction skill has an extremely powerful advantage in finding out the news, after quietly extracting the souls of several undead masters in the early stage of the fifth order, Cheng Yang finally got a piece of information about a king-level undead.

It was a zombie king, although the rank was only at the peak of the fifth order, but the actual combat power was as high as the early stage of the sixth order, and among the undead clan, it could be regarded as a powerful person. Such an existence has the opportunity to become a false god.

Such a zombie king is undoubtedly the best for Cheng Yang, if the actual combat strength and rank are both in the early stage of the sixth order, it will be more troublesome for Cheng Yang. Who made Cheng Yang's trapped god cage only effective against fifth-order or lower targets, at least until he obtained a sixth-order psionic stone, Cheng Yang would not be able to control sixth-order targets.

The zombie king lives in a castle of the dead, which is located in the western part of South America, a pre-apocalyptic region of Peru.

Since South America has become a territory of death, the whole of South America can be said to have changed the world, the recognizability of the territory has been greatly reduced, and one will get lost if you are not careful, after all, everywhere you look, there is black ground, trees, buildings, mountains and rocks, except for flat land, there are undulating black sand dunes.

Plus there's dead air wafting everywhere. The line of sight is affected, and it is really not easy to find a target.

As for the borders that existed in the past, they no longer exist in the Realm of the Dead. This is also the power of the Death Territory as a taboo-level secret art, it can even change the rules of heaven and earth to a certain extent, and even the rules of heaven and earth can be changed, not to mention the terrain that is used as a barrier between countries.

With the help of a compass and capturing the undead along the way to extract souls, Cheng Yang finally arrived at his destination three days later.

Still far away, Cheng Yang could already see some zombie activities.

It's different from the chaos of all kinds of undead in other places. The place was full of zombies, and the whole space was filled with the smell of rotten flesh. This aura has a strong toxin, and if a first- or second-order creature is in this environment, it will soon be poisoned to death.

Cheng Yang was not afraid of this toxin, and after determining the location of the Castle of the Dead, it only took him a few minutes to come to the sky above the Castle of the Dead.

Cheng Yang was immediately shocked by the castle below.

Cheng Yang had also seen a lot of undead stations before, but they were all village-level stations, which looked like small tribes in the countryside. Disorganized, shoddy......

But this castle is extremely magnificent, the whole castle is semi-enclosed, surrounded by dozens of zhang high walls, the city wall is not made of stone. Rather, it was a super-concentrated bone condensed condensation, and strengthened by the black rain falling from the Death Territory, the entire city wall showed a metallic black luster.

The castle covers an area of more than 10 square kilometres, and most of the castle area is covered by buildings. The style of these buildings is very different from that of the East, and they look a little dilapidated, but they are extremely strong.

Cheng Yang didn't search the area with his mind anymore. Although his strength is stronger than that of the Zombie King, if his spiritual power is raging, I am afraid it will be difficult for the Zombie King not to discover him.

Half an hour later, Cheng Yang searched the entire castle, but did not find a guy who was suspected of being a zombie king, which made Cheng Yang quite entangled.

Could it be that the Zombie King was not in the castle at this time? Cheng Yang felt that it was unlikely, the undead clan was different from other races, the stronger the undead clan, the less they liked to move, and sometimes it was even possible to sleep in one place for years or even decades.

What's more, according to the information he got before, the Zombie King has been in retreat in the castle since he returned from the vicinity of the Yellow Spring River. In fact, not only the zombie king, but also the rest of the king-level undead and the undead emperor are also in retreat, because of the emergence of the death territory, they ushered in an opportunity to evolve, although for the undead whose strength has reached the king level or even the emperor, the possibility of this opportunity to make them evolve again is still very low, but it is always much stronger than the slim chance on weekdays.

Cheng Yang estimated that this zombie king must be somewhere in this castle, but he didn't find it.

In this case, Cheng Yang had to take the risk of doing something else, and immediately he found a zombie leader in the castle who stayed alone in a dark room.

The strength of this zombie leader is as high as the late fifth order, although it is still too far behind the zombie king, but it can be regarded as a master in this castle of the dead.

Naturally, it won't be a good thing to be found by Cheng Yang, this guy almost didn't have any ability to resist in the face of a master like Cheng Yang, and he was controlled on the spot. Cheng Yang's Freezing Technique not only did not weaken after the change in the rules of heaven and earth, but became more powerful.

A wisp of soul was extracted from the mind of the zombie leader, and it didn't take much time for Cheng Yang to find the information he wanted.

It turns out that in this castle, the upper floor is only where ordinary zombies and some zombie leaders live, and there is also a dungeon under the castle, which is the core area of the entire castle.

If it was an ordinary person, it would be very difficult to enter the castle's dungeon, even if the strength had also reached the early stage of the sixth order, it would be impossible to do so. But for Cheng Yang, the enchantment on the periphery of this dungeon is just like that, although the undead clan's research on the enchantment is stronger than that of the beast clan or the barbarians, but in the face of Cheng Yang's void secret crossing skills, it is completely useless.

According to the information obtained from the memory of the zombie leader, Cheng Yang easily entered the dungeon.

Cheng Yang was shocked by the scene in front of him, only to see that the walls and ground of the underground palace were covered with purple-black bloodstains, and the smell of rotten flesh inside was even stronger than outside.

"These zombies are perverts!" Cheng Yang muttered in his heart.

Cheng Yang entered the main hall of an underground palace at this moment, with an area of at least more than 100,000 square meters, and in the center of the main hall, there was a statue of a god, which was more than ten zhang high, and the statue held a huge sickle in his hand, exuding infinite might.

"Is this the legendary god of the underworld?" Cheng Yang muttered to himself in his heart, he had heard before that the undead clan believed in the god of the underworld, and the god of the undead was also the supreme god of the undead clan.

Cheng Yang just glanced at the statue of the god of the underworld, and felt that his mind was attracted by the other party, this statue was indeed too weird, the statue of the ancestor god he saw in the residence of the Ice Clan at the beginning could not reach this level.

However, Cheng Yang's will was indeed firm enough, but he retracted his mind in an instant, and he didn't dare to continue to observe the idol.

At this time, Cheng Yang began to look at the situation around the main hall, around the main hall, there were nearly fifty stone gates, each stone gate was ten meters high, and the width was five or six meters.

"These stone gates ......" Cheng Yang was secretly shocked in his heart, he could even feel that there were almost strong energy fluctuations behind each stone gate, I am afraid that there were powerful existences behind these stone gates.

There are more than 50 stone gates, which means that there are more than 50 undead powerhouses in this castle. Of course, these powerhouses are also relative, and there are quite a few energy fluctuations in them that only reach the level of the middle of the fifth order. Such an undead is a well-known master outside, but it is not enough to see in front of Cheng Yang.

Cheng Yang was not interested in these fifth-order undead for the time being, even if he wanted to attack these undead, he would have to deal with the zombie king first.

Relying on his keen perception, Cheng Yang found that behind the statue of the god of the underworld, there was a stone door with a particularly obscure breath, if it weren't for Cheng Yang's full spiritual perception, I am afraid that he would not have been able to find this breath.

Cheng Yang couldn't judge the strength of the other party from this trace of aura, which was completely different from the situation behind the rest of the stone gates.

It is estimated that the existence behind this stone gate is a guy with the same strength as Cheng Yang, and the only one who can meet this condition in the entire undead castle is the zombie king.

Then Cheng Yang continued to hide in the void, moving towards the stone gate, and in an instant, he came to the stone gate.

At this time, Cheng Yang naturally couldn't come out of the void without any hindrance, and he relied on the advantage of the secret technique of the void secret crossing to pass through the stone gate without any obstacles.

What caught Cheng Yang's eyes was another scene, this was also a wide hall, but there was no statue in the hall, only a huge coffin.

Let's call it a coffin, it's too big.

The style of the whole hall is like an ancient tomb sealed underground for 10,000 years, and all the ornaments and carvings exude a pale and simple atmosphere.

Cheng Yang felt very strange about this phenomenon, this undead clan had not occupied this place for more than a year, if the buildings could be built quickly through special rules of heaven and earth, but this ancient atmosphere was difficult to imitate.

Maybe everything here, including the coffin, was brought from another world.

Suddenly, Cheng Yang smiled bitterly, he realized that his purpose was just to kill the zombie king, but now he was entangled in the carving and ornamentation here, but he put the cart before the horse.

At this time, Cheng Yang turned his gaze to the big coffin in the center of the main hall, which was more than fifteen meters long and more than three meters wide, which was very eye-catching anywhere.

The black gas visible to the naked eye around it was constantly converging towards the coffin, disappearing from the surface of the coffin out of thin air.

And these black qi are all dead qi that makes any living creature fear. (To be continued.) )
