Cheng Yang watched from a distance of four or five hundred meters away from the corpse group, and those zombies did not notice Cheng Yang, and they all moved aimlessly.

On the contrary, those big maggots on the ground were all lying motionless on the ground, if it weren't for the occasional green liquid squirting out of the mouths of some maggots, Cheng Yang would really feel that it was just a pile of rotten meat.

Soon, Cheng Yang's observation came to fruition, and he found that these zombies were all moving in a fixed circle and never left this range.

"Is this a zombie colony?" Cheng Yang muttered in his heart, "Or is this their lair?" ”

"That's not right, these undead don't need to eat, what are they doing with a nest? And there are no buildings here, but they are all standing still. Could it be ...... What are they guarding here, or is there something special about the ground here? Cheng Yang couldn't figure out the situation at all.

There is no doubt that this group of zombies is very dangerous, if it is just to complete the national border mission, Cheng Yang feels that he does not need to provoke such a large group of zombies, it is a big deal to return to the original place, continue to step on the thunder, and find more zombies to kill.

Anyway, he had already killed more than 8,000 zombies just by going in a straight line before, and now it's a big deal to go back and take some detours.

Thinking of this, Cheng Yang turned around and left directly, in this weird forbidden demon space, Cheng Yang didn't even have a sense of security, especially now that he couldn't use magic skills, he didn't even have room for temptation.

Even if he wanted to test it, Cheng Yang felt that he needed to verify whether he could use ablation skills first.

This is the forbidden space, and what is forbidden is magic skills. But dissolving is an exclusive skill for the Son of Ice. The Son of Ice is not considered a mage, so it is likely that this skill can be used.

The reason why Cheng Yang didn't verify it in the past was because the cooldown time of this skill was too long. so that he does not dare to use it easily. Even if you test the skill and use it, wouldn't it be even more tragic if you encounter danger later?

However, despite more than ten days of exploration, Cheng Yang also summed up some rules, in this forbidden demon space, as long as he explores step by step, he will basically not encounter any danger. Compared to undiscovered dangers. Those zombies are the biggest danger.

Cheng Yang has an intuition, I'm afraid that he will encounter that group of zombies again, as for why he has such an intuition. Cheng Yang himself couldn't say clearly.

Cheng Yang walked back for more than an hour, and he finally understood why he had such an intuition, because he had already returned to the area where he had killed zombies before, but he still hadn't encountered a single zombie.

"Something is wrong!" Cheng Yang thought of a possibility.

He thought of the time he had killed the skeleton soldier himself. When he killed almost nine thousand skeletons. Then enter the border zone between zombies and skeletons.

At that time, in order to be able to successfully complete the task of killing skeleton soldiers, he deliberately walked around for a while. After killing 10,000 skeleton soldiers, he went directly into the zombie area and did not kill another skeleton soldier.

Cheng Yang only felt that he had grasped the timing just right, or maybe it was a coincidence, so he didn't think much about it. But now that I think about it, I'm afraid it's not a coincidence, and it's not because I'm good at seizing the moment. It's the rules of the land.

According to the explanation of this frontier mission, 10,000 of each of the four undead creatures need to be killed. I used to feel that I was in this forbidden space. There may be a lot of undead creatures out there, at least skeletons and zombies. Otherwise, he would not have been able to kill so many skeletons and zombies so smoothly.

Now that I think about it, there are indeed a lot of skeletons and zombies in this world, but when you kill a certain number, the extra skeletons or zombies will disappear, instead of allowing yourself to kill indefinitely.

This also seems to be understandable, if there are really endless undead creatures waiting to be killed in this forbidden demon space, wouldn't his cultivation progress be able to continue to improve at such an extremely fast speed until there is no longer any effect?

There's no way the gods have left such a huge hole for themselves to exploit, right? Cheng Yang was slightly disappointed in his heart.

It's just that in this way, I have to face that group of zombies again.

Cheng Yang couldn't help but smile bitterly, it seemed that his intuition was really accurate.

Cheng Yang then wandered around for a while, and after making sure that there were no more zombies to refresh, he made a decision in his heart.

He first returned to a place that was only more than ten kilometers away from the zombie swarm, and did not rush directly towards the zombie swarm, but prepared to use the ablation skill.

Only after testing that this ablation skill could be used in the forbidden demon space, could he rest assured that he would boldly go to meet those zombies.

As Cheng Yang's mind moved, that familiar feeling came from his body, and his body really succeeded in turning into a pile of liquid.

"It seems that my guess is really correct, the Son of Ice is not a magic class, and his exclusive skills are not magic skills." Cheng Yang was overjoyed.

Now that the ablation skill is used, Cheng Yang is not ready to waste it, he is ready to take the opportunity to check on that group of zombies to see if he can find out the details of that group of zombies.

Cheng Yang sank the water liquid turned into his body into the ground and began to move in the direction where the zombie group was, only then did he realize that his speed in the ablation state had been affected. The originally powerful speed can only play 30%.

Cheng Yang didn't know if the reduction in speed was due to the effect of the forbidden demon space, or because of the effect of the huge amount of dead qi contained in this black earth, but no matter which factor it was, this result was already in front of Cheng Yang, and the only thing he could do was to accept it.

Although his speed slowed down, it only took him about half a minute to reach the place where the zombies were entrenched.

None of the zombies or maggots noticed Cheng Yang's approach, and everything was running as usual.

"Rush in and have a look." Cheng Yang plunged directly into the zombie group.

Looking up from the ground, the zombies look like mountains of meat, towering on the ground like this, and their hideous faces are enough to scare people out. As for the violent corpse smell, Cheng Yang could still smell it easily, which also made Cheng Yang very criticized.

The ablation skill is powerful, even if the body turns into water, the original five senses are all complete, he can see, hear, smell, taste, and feel, Cheng Yang used to think that this was a good thing, but now Cheng Yang asked about the thick smell, and there was no pleasant feeling in his heart.

When he didn't use the ablation skill, he could at least cover his nose with a cloth or hand, but in the ablation state, he couldn't do anything but let the stench rage on his nerves.

Fortunately, Cheng Yang's nerves were definitely thicker than a bucket now, and these tortures were not enough for him to collapse, so it didn't take him much time to wander around most of the area below this group of corpses.

When he reached the heart of the corpse, he found something that shocked him.

This is......

Sleepy Dragon Order.

Another trapped dragon order.

Cheng Yang also has some speculation about the role of the trapped dragon order, this may be an opportunity for human beings to escape from this doomsday cage, and the trapped dragon order is a ticket, as long as they get this token, it is estimated that even if the evolution of this world fails, they can live smoothly.

Of course, if the Earth can eventually evolve successfully, this Dragon Trapping Order may not have much value.

However, all this is just Cheng Yang's speculation, whether this trapped dragon order still has a powerful effect will have to wait for the mystery to be revealed later. Perhaps, it all depends on what kind of place the True Dragon Domain is reached by using the Trapped Dragon Order.

When Cheng Yang first got the Trapped Dragon Order, he felt that this thing must be precious, but now that he hastily discovered another side, there is no way to judge whether this thing is scarce or not.

In fact, he didn't want to think about it, the first time he got the Trapped Dragon Order was because he cleared the cyan tower layer, and now he found this Trapped Dragon Order, and it was in the forbidden demon space in the national border mission, and it was surrounded by thousands of zombies.

In either case, it would be extremely difficult to get the Trapped Dragon Order.

But now that he meets Cheng Yang, who has ablation skills, the result becomes unpredictable.

Cheng Yang's heart was full of pride, when others encountered this situation, I am afraid that there would be no other way than to attack. Even if he is a master of the stealth technique, once he picks up the trapped dragon order on the ground, he will inevitably be besieged by the surrounding zombies, and the stealth technique will be broken in an instant.

But Cheng Yang is different, his ablation skill is an invincible state, even if he takes the trapped dragon order to attract the attention of the zombies, the other party is helpless.

Moreover, Cheng Yang has a guess that these zombies should be guarding this piece of trapped dragon order, so once the trapped dragon order disappears, will these zombies disperse directly? If this assumption is true, it will be much easier to destroy this group of zombies.

Thinking of it, Cheng Yang immediately controlled a cloud of water to emerge from the ground and slowly covered the trapped dragon order.

The whole process was completed in a few seconds, and then Cheng Yang's mind moved, and he was about to receive the trapped dragon order into the storage ring. He had done this action countless times, and he had collected items that were much more complicated than the Trapped Dragon Order, and there had never been an accident.

However, what happened next was something he didn't expect, and the Trapped Dragon Order remained in place.

What's going on? Can't even use your storage ring? It's impossible, I've accessed a lot of things from the storage ring these days, and I've never had a malfunction.

The only explanation is that the Trapped Dragon Order cannot be collected, at least not for now.

Cheng Yang tried it a few more times, but it still didn't work, and he had to give up this practice.

"It seems that there is still only a strong attack." Cheng Yang sighed in his heart, "This trapped dragon order should be related to the zombies guarding the treasures, kill all these zombies, and you should be able to get the trapped dragon order." ”

Cheng Yang's speculation is not unfounded, the existence of a connection between the guarded treasure and the guardian beast is not a top secret, even in the outside world, there are many demonic beasts whose strength has been improved because of the protection of the treasure. It is not incomprehensible that this is happening now. (To be continued......)
