Suddenly, a figure flashed behind Weiyang and Zhu Zuo, and their hearts were shocked at the same time, and they hurriedly turned their heads, but they didn't see anything. There was only a feeling of being spied on at all times. And at this time, the dead qi that permeated the sky did not attack again, but slowly gathered in the same place.

Weiyang and Zhu Zuo glanced at each other, and they both saw each other's questions. "Zhu Zuo, while the dead qi is condensing now, let's get out of here quickly. "If you can't think of it, you don't want to. There is no retreat, only forward.

Zhu Zuo didn't hesitate and said after glancing at the condensed dead qi: "Well, let's go!" After speaking, he put away the remaining nine demigod killing arrays again, and the four wings vibrated through the sky and flew towards the interior of the immortal mountain range. The original ten killing arrays destroyed one when the spatial gate exploded just now.

As soon as they left, a vague figure suddenly appeared in the increasingly thick dead air, staring indifferently at the two who had left. Then it slowly faded away in dead air.

"What the hell is that? I always feel like there's something hidden behind us!" asked Weiyang, sitting on top of Zhu Zuo's head with a faint purple disc all over his body. Although the death qi no longer attacked, he didn't dare to be careless, and surrounded his body with the little mana left in his body. The concentration of dead qi behind them is getting higher and higher, and it is already about to condense and solidify.

Zhu Zuo's huge head shook and almost knocked Weiyang off. "What are you doing!" Weiyang tilted his body and hurriedly grabbed the giant horn beside him with both hands.

"Sorry, I didn't mean to. Zhu Zuo said with a smile, his wings kept vibrating, and he didn't dare to stay for a moment Who knows what will happen after the dead qi gathers. "I'm not sure about that. It stands to reason that there should be no life in the Undead Mountains. ”

Indeed, no life can live in so much dead air for a long time. Unless you reach the realm of the gods, you can effectively cut off the connection between the life and the death of the outside world, and not be eroded by the death of the outside world. "Alright, big brother, stop your inferences that the whole continent knows. Weiyang glanced at Zhu Zuo and teased. "This inference of yours is known to three-year-old children on the mainland, can you say something else?"

"What!" Zhu Zuo was not happy, "you find a three-year-old child for your uncle who knows these secrets." Uncle, I don't believe he's a three-year-old kid who knows more than I know. Don't say he's three years old, even if he's four years old, I've just compared him to him!" he had a proud expression on his face when he said this, as if Weiyang had insulted his IQ.

The corners of Weiyang's mouth twitched and he thought, "He can only mix at the age of three or four." There was nothing to worry about with such a four-year-old child, Weiyang resisted the urge to laugh in his heart, and asked, "Okay, you have won! There are no more four-year-olds on the mainland than you know." ，”

"That's!" Zhu Zuo heard Weiyang admit defeat, and his forehead almost fell off with pride. Fortunately, Weiyang was prepared in advance, otherwise he would definitely fall.

"Okay, do you have any other conclusions?" asked Weiyang dissatisfied, angry with such a mentally retarded fellow.

Suddenly, Zhu Zuo's body, who was moving rapidly, trembled, "Xiao Yangzi, why haven't we seen anything for so long?" Except for a few skeletons on the periphery, nothing else was seen. It's so unreasonable, and there should be other undead creatures.

After Zhu Zuo asked this, Weiyang thought of something that Zhu Zuo had said when he was in West Lake before. Although there is no life to survive in the undead mountains, there is an undead creature that can survive in the midst of it. What it is, few people can say. Some say it's some skeleton, others say it's some creature that has been cursed to die but can't dissipate.

"Undead creatures!" Weiyang blurted out in shock.

Zhu Zuo's face was also solemn, and he thought of the description of the undead in the outside world. The undead are of unknown shape, powerful in battle, and devouring life. There are only these twelve words, although there have been many wars in the Immortal Mountains since ancient times, but none of the secrets have been described in detail. At most, I would like to mention how tragic the war was at that time. It seems that someone is deliberately hiding everything here, and it is still unclear what the undead are, some say that they are skeletons and zombies. But a lot of people don't think so.

Although people nowadays know very little about the undead, according to some legends, one thing is certain, that is, the combat power of the undead is very strong. Otherwise, it would not have annihilated the tens of millions of troops led by the Heavenly Machine Gods.

They all raised their vigilance and watched everything around them closely. Without the slightest stop, he quickly drove towards the center of the Immortal Mountains. Zhu Zuo took out a few hundred Yuan Stones and asked Wei Yang to recover his mana first, and he himself absorbed the Yuan Qi in the Yuan Stone while flying. There may be danger here at all times, and you must always maintain the strongest combat power.

The earth was lifeless, and the sky was dark. Only bare rocks are bare on the surface, and the surface is rugged and rocky. The rocks here are all russet, dyed with the blood of countless powerful people in ancient times.

There was no life, no birds and beasts, and Zhu Zuofei looked very low at the blood-stained rock, revealing a wisp of sadness. "This is the blood shed by the strong men of various races in ancient times in order to stop the undead creatures, tens of millions of troops buried the bones of the undead mountain range, the blood stained the entire undead mountain range, and the corpses piled up into a mountain range. It's just for future generations to survive, it's not easy for our ancestors, but we can't wash away their shame, it's our unfilial piety!"

Weiyang was gloomy for a while, everything was for survival! The ancestors used their flesh and blood to pave the way for future generations to live, and there was no complaint about going forward and succeeding. "The merits of our ancestors will not be forgotten by future generations. "Won't you really forget? Weiyang is not sure, the current human race is fighting openly and secretly, and the insidious and cunning really remember the merits of the ancestors?

Suddenly, a rock wall that reached into the sky appeared in front of it, and there was no end in sight, and it could reach straight into the sky. Zhu Zuo looked up at the cliff and shook his wings to fly, but there was a strange force in the sky blocking the top, and even if Zhu Zuo had wings, he couldn't fly.

"This ...... How is this going to pass? There is no road!" Zhu Zuo stayed in mid-air, looking around.

Weiyang is also observing everything around him, the cliff wall has weathered after thousands of years of wind and rain, and it is uneven, with many protruding rocks. Zhu Zuo flew along the cliff, looking for a way. Weiyang looked at the traces on the cliff, many of which were left by the battle. There are also ancient texts from ancient times, and it is impossible to identify what content is preserved to this day. It is too far away from now, and the various ethnic groups do not know how many Chinese characters have evolved, and the ancient characters on the cliff wall are simply unrecognizable.

After more than ten minutes of flight, I finally found a canyon, the canyon is surrounded by cliffs on both sides, there is no grass, only a trace of the sky can be seen, it is a veritable ray of the sky.

Zhu Zuo shrank his body again, and his length was only about one meter, and Weiyang also jumped down. They were about to hike through the canyon, one beast in front and one behind, and they entered the canyon.

They were very careful, this was the only way to get to the heart of the Undead Mountains, which must be full of dangers.

"What!" Zhu Zuo, who was walking in front, suddenly stopped and shouted, full of incredulity. "This ...... Countless formations have been laid here!" Weiyang also followed his gaze, only to see countless formations carved in the canyon in front of him. On the ground and on the cliffs on both sides are full of patterns. This is the world of formations.

"It's all ...... It's all a killing array left by a demigod!" Zhu Zuo stammered a little as he spoke excitedly, "It's developed! It's developed now! Just understand and comprehend a few demigod arrays to destroy the supreme sect master!"

Weiyang moved cautiously, there were many formations inlaid on the rocks here, each of which was a boundless killing array. If it is triggered, it will definitely be nine lives and one death, or even death. "Zhu Zuo, are these killing arrays really gods killing arrays?" his face was extremely solemn, and at the same time, his face was full of shock.

"Most of them are demigod-level killing arrays, and only a small part are god killing arrays. Zhu Zuo resisted the thought of collecting the killing array and said, now is not the time to collect the killing array. There are pursuers behind them. The most important thing now is to get through this canyon as quickly as possible.

Each battle is not very large, but there are countless of them. And each formation is intertwined and affects each other. As long as one killing array is triggered, dozens of killing arrays will be attacked at the same time.
