A blood red knife with the length of two people appeared in his hand“ You all stand back The demons will retreat. But the spirit knife's face is slightly pale, there are thin beads of sweat on the forehead sliding down. But there was no fear on his face, and he walked towards Yin Wuji step by step. Even if he knew that he was defeated, he would not step back. Because the demons believe in being strong, brave and indomitable. However, at this time, Yan Wuji's face changed greatly, and suddenly turned to the South sky. His face was full of incredible light, and his body trembled unconsciously. The flame of the nether world, which had been blooming behind him, disappeared. The spirit knife is surprised in the heart, also follow his vision to see. It doesn't seem to be special? Why? incorrect! It's noon in the sun. But at the end of the southern sky, there was a red glow. And with the passage of time, the rosy clouds became more and more dazzling, and even later the blood red seemed to be stained with a faint black air. It's like a fire burning the sky and clouds until they're all burnt to ashes. Yin Wuji's face was full of horror, and there were fine beads of sweat rolling down his forehead. He trembled his lips and hissed, "no way! Impossible... How can he succeed? " The bewilderment in the demon knife heart is more and more deep. What happened to the rosy clouds all over the sky, which made Yin Wuji, who had always attached the most importance to identity and face, show such a gaffe expression in the scope of their demons. The goblin asked. But Yan Wuji disappeared in the same place. Then, not an hour later, the army of the netherworld stationed in the northwest corner of the ancient battlefield of death left. Even the huge and luxurious palace disappeared in a flash“ It's really evil! " Tianhe said suspiciously, "before Ming Ming, they were the ones who yelled to fight with the polar region quickly. Now they are the ones who run away like burning butt. Are those idiots in the netherworld brain broken?" The goblin frowned and couldn't help looking at the southern sky. At this time, the scene of burning clouds has disappeared, everything is calm as usual. But the demon Dao felt that something must have happened in the netherworld. Otherwise, Yan Wuji would not show such a frightened expression, and would not lead the soldiers away in a hurry. The goblin told the previous performance of Yin Wuji. Everyone couldn't help but look puzzled. Minwei frowned and said, "demon, now the netherworld has retreated, what should we do? Will we go to war with the polar regions? " For a moment, everyone's eyes were focused on Jun Jitian. The demons are all warlike, so they would not like to run away with their tails between them before they fight. But the demons also respect the strong and are the most loyal. So as long as their demon king kills a day command, all the demons will not hesitate to comply. Junjitian's face was cold and his brow was frowning. Looking at the camp where the polar region is located, the eyes are full of strong intention to kill. The cruelty and warlike factors in Tianhe's bodies are also intrigued. Just wait for Jun Jitian to say "kill". However, after waiting for a moment, he heard Jun Jitian gnash his teeth and say: "send orders to the whole army, retreat!" What? Just now, the demon master clearly had a murderous look on his face. How can he say that the whole army did not attack, but withdrew?
