"Are you a rune master?" Kong Jue exclaimed and took a step back. All his offensives were instantly destroyed by Mo Heng. The air around him suddenly heated up, but it seemed strangely as if there was another gloomy coldness.

It was like flames and ice crisscrossing, forming a ball, attacking mixed together, making people unable to resist. Kong Jue, but seeing the faint blue flame, his ice divine palm could not break him, and there was a sense of fear in his heart. But after seeing this, Shangguan Xue, his palms flowed together, and the ice aura was like the breath of the Beiming Ice Dragon, as if twisting into a ball of twists, attacking the faint blue flame intertwined. [bsp;    "Ignorance!"

Mo Heng sneered, without any movement at all. He just stopped and watched the blue fire dragon swallow the extremely cold ice palm. Kong Jue and Shangguan Xue retreated repeatedly, both of which were defeated, and they had never seen such a move in their hearts. At the moment, they guessed that they were probably not a warrior, but an attack formed by the strength of the fifth-grade rune master and above, activate the spiritual energy condensed. But Yao Shuang was worried that Nie Xin's heart was not less than Mo Ru who was standing at the door. She actually pulled out the long sword at her waist, and thousands of lotus flowers appeared immediately. This martial art was extremely mysterious. Mo Heng finally felt a little moved. He took a step back and shot out a blue flame with his left palm!

The long dragons intertwined between the world, and were extremely terrifying. Almost no one in this space could defeat Mo Heng's offensive. Just when Kong Jue and Shangguan Xue were preparing to rescue Yao Shuang, they found that it was too late!

Yao Shuang's thousands of lotus sword energy were frozen in the space, and then turned into balls of flame embers and fell on the ground. Yao Shuang had never seen such a strange attack and didn't know what to do at the moment, but when the two blue dragons were about to penetrate his chest, a white light flashed, and the burning flame seemed to fall in the scorching sun, and the white light seemed to burning the comets in the sky, adding an unbearable temperature to the space in an instant.

A young man suddenly appeared in front of Yao Shuang, and then wrapped his left arm around him and instantly hugged him in his arms. He smiled gently, and his handsome and handsome figure stood quietly in the air, facing the pressure of the old man Mo Heng, he was fearless at all!

"Hmph, we're meeting again!"

Of course, Nie Xin had no good feelings for Mo Heng, but Mo Ru, standing at the gate of the ancient city, found the boy's return in an instant. Her red lips opened and closed, and a scream resounded through the world!

"Nie Xin!"

Yes, the boy was Nie Xin. He smiled and nodded to Mo Ru, saying, "I'm fine, don't worry, if it weren't for your voice transmission, I'm afraid I'm still wandering in the ancient city and looking for it aimlessly. Mo Ru, I'll take you out of this place now!"

Nie Xin shouted loudly, and an ancient formation appeared behind him. In the middle of a strange circle, a triangle was constantly coiling and rotating, and there were fifteen circles, but except for the black circle, the others were empty!

The black crystal in the black circle immediately shone a deep black light, like the gloomy and powerful aura of death, turning this space into a spinning vortex in the deepest abyss of hell!

A terrifying suction force swept through this space. The huge centipede seemed to have discovered something, screamed and twisted its huge body. Mo Heng saw this and jumped down, but seeing that the centipede seemed to be shocked by some kind of pressure, she knelt there in an instant, and even shouted, struggled, and rushed into the ground, which finally escaped, as if she had lost all resistance in an instant, just like she had encountered her natural enemy, or her destined master!

Nie Xin smiled, pointed with one hand, and a black sharp blade rose up from the sky, then swept down, and actually regarded Mo Ru as a rabbit. The black sword energy was like a soaring eagle, with its wings spreading in an instant. Although the area covered was not large, for Mo Heng's figure, it was like a huge net, wrapping it in an instant!

The blue flames instantly rose into the sky, and Mo Heng did not give up, but the black flames were really strange, as if they could swallow their own blue flames. In an instant, the blue flames returned to the shadows and were swallowed into the black flame sword!

boom!

A loud blast in the air, coupled with the black flames attack, it seemed as if a group of rushing black panthers were roaring in the air. The power in his body could probably swallow Mo Heng's whole body in an instant, and then burn it to ashes!

Mo Heng turned around and did not look at the black flames in the sky, nor at Nie Xin. Instead, he looked at the strange rotation array behind him!

"Three or five heavenly seal!"

Mo Ru and Yao Shuang both discovered this strange seal, but Mo Ru knew it, but Yao Shuang didn't.

Mo Ru closed her mouth and exclaimed, feeling mixed emotions. She didn't know what to say, but Nie Xin smiled and said to the second girl: "Don't worry, I've been in a breakthrough this time. I'm no longer the same as before. I should thank this old man."

Mo Ru hurriedly shook her head and said, "Nie Xin, stop beating, he, he is my eldest brother!" Nie Xin also guessed a little, but you are still angry in your heart. Mo Heng is a rune master. Although the power of the blue fire is very mysterious, it is impossible for him to be able to defeat the abyss black fire he had just absorbed, let alone the fiery flame of Nie Xin, who has been promoted to the fourth-level rune master!

After a battle in the ancient city, Nie Xin also knew that his white flame blade contained unparalleled power, but this power may only be used as a general means to attack the warriors, but when dealing with the rune master, it seems that the most mysterious method in the world can not only devour the opponent's spiritual energy, but also the dark blue flame formed by the opponent's spiritual energy!

Mo Heng also knew the power of Du Tian Seal, and immediately gave up resistance. He was now tied up by the chains of the Emperor of Heaven and could not exert any martial arts power. He himself knew that this was Du Tian Seal, and even knew the origin of the black fire. He immediately knelt on the ground and shouted loudly: "You, are you Yin Tian? Little, the villain is rude!"

Nie Xin was also a little surprised. Why did Mo Heng have such a big contrast? But I think it should be because of the three or five heavenly seals. Although he didn't know what he had to do with Yin Tian, ​​he should be attributed to him after learning the Yin Tian Art! Without saying much, he smiled and said, "Why, you won't fight?"

Mo Heng shook his head and said, "Since you have obtained the black fire in the abyss, I don't have to protect this ancient city anymore. Can you do it for me?" Nie Xin was puzzled. He was an enemy before, so why did he help him this time?

Unexpectedly, Mo Ru rushed forward and shouted loudly: "Nie Xin, don't hurt him, he is my eldest brother!" Nie Xin immediately understood, so she asked, "Then why are you here?" Mo Heng also told Nie Xin about the future and the end of the world.

It turned out that he was also a powerful figure in the Black Cat clan, but unexpectedly, he met the Emperor of Heaven and was subdued, and was brought to this place. He was sent here with shackles that could ban the power of his warriors. He was sent here to guard the ancient golden city and protect the things here otherwise they would be violated by outsiders. But who knew that Nie Xin had obtained the black smoke from the abyss when he entered. Although he had to use improper means, he could be regarded as helping him complete the task!

Because the Emperor of Heaven once stipulated that if someone could enter the ancient city and get the black flames of the abyss, he would not have to stop him and let him leave even if he left. As for how he left, it depends on whether the man was willing to use the black flames of the abyss to save him.

Mo Heng had thought that he would get the black flames of the abyss by himself, but whenever he wanted to get in, the chains became extremely heavy, as if he knew his thoughts, which made him stagger when walking, not to mention a clever activity. In the ancient city where crisis was step by step, he turned danger into a barrage and seized the black flames of the abyss in the ancient city.

After Nie Xin learned about this, he laughed and shook his hand and burned the chain instantly. It was strange that the dark blue flame, no matter how it burned, the chain remained unmoved. But now Nie Xin used the black fire of the abyss, but in just a blink of an eye, he turned him into powder smoke and dust and dissipated.

Seeing this, Mo Ru was happy, and immediately grabbed Nie Xin's hand and said with gratitude: "Nie Xin, thank you!" Shangguan Xue and Kong Jue did not know what Mo Ru's identity was, and Yao Shuang was even more encouraged. She immediately became angry and shouted loudly, pointed her jade hand at Mo Ru's nose and cursed: "Who are you? Why are you so unfaithful?"

Seeing this, Mo Heng was extremely lucky to be able to escape from his life in shackles, but he didn't expect that such a thing happened. He had never known much about men and women, and immediately said, "Sister, you?"

Speaking of this, he also guessed that Mo Ru seemed to have been moved by Nie Xin and stopped talking. What's more, he couldn't beat Nie Xin, and even accepted Nie Xin's life-saving grace, so he had to stay aside, look at the human-faced centipede beside him, and sighed softly: "Brother Centipede, our mission has been completed! We can finally see the light of heaven." Centipede obviously didn't understand what Mo Heng said, but looking at Nie Xin's smiling face, it seemed that there was no murderous intent, and his heart finally relaxed. The human-faced growing on the centipede's head also smiled embarrassedly and let out a slight cry.

Seeing this, Nie Xin was speechless. He was the worst at dealing with such things. Now he stood between the two girls and shouted, "Stop!" But with Yao Shuang as the first step, he not only did not stop, but instead took the lead, thrust his sword and stabbed Nie Xin's vest, and cursed: "Bastard! Why are you going to have another woman?"

How could Nie Xin explain? Mo Ru started first and followed her. If you want to talk about it, she was the first one. But Mo Ru smiled and said, "Yeah, why, are you the woman Nie Xinxin looking for? Why don't you pay a visit to your elder sister quickly?"

Yao Shuang shouted coldly, Nie Xin captured the sword tip with one hand, but cursed: "Shameless, who is the eldest sister!"

Mo Ru pointed to herself and smiled and said, "I'm the first, of course I'm the eldest sister. Why, can you, the last concubine, want to be a big shot?" After that, she flew into a charming look and looked at Nie Xin. Who knew that she was happy because Nie Xin let her brother go, or because Nie Xin returned safely, and actually started this charming joke. Although Nie Xin had been used to it for a long time, but it was unknown that it was the first time that Yao Shuang could not tell whether it was a joke or a truth. She was so angry that she was itchy, and her eyes were covered with a layer of moist color!

"Nie Xin, you, you are very kind! Me, me!"

Nie Xin hurriedly stepped forward and said, "Yao Shuang, listen to me to explain it to you!" After that, he also took back the mighty Sanwudu Tianseal behind him, but Yao Shuang seemed to be not worried about what happened to Nie Xin in the ancient city. She immediately pointed at Nie Xin's nose and scolded, "Bastard, I'll go, let's go!"

Nie Xin was speechless, but when Yao Shuang's figure instantly flew into the small hole, he used the lotus sword energy to create an amazing deep pit! The originally small exit was expanded to the point where a person could enter at will!

Nie Xin saw the escaped white figure and hurriedly chased after him, but when Mo Ru smiled slightly, shook her head, and said, "This is your business, I won't interfere!" He also knew that Mo Ru must be joking. He could still understand and respond freely when dealing with the opponent's moves in the battle, but now facing the two women's jealousy, he was worried!

"Forget it, I'll go and get her back first, wait for me!" After that, he nodded at Mo Ru, then clasped his fists at Kong Jue and Shangguan Xue, then stepped on the breeze and jumped into the gap in the mountain wall!

Seeing this, Mo Heng sighed and said, "Sister, I'm free, where are you going?"

Mo Ru shook her head and said, "I want to find the Yuntian Stone to save my mother, but I have no clue!" Mo Heng looked at Shangguan Xue and Kong Jue with vigilance, sighed softly, looked at the exit of the mountain wall, but smiled and said softly, "Do you have no clue? Perhaps, Nie Xin is the best clue. After all, the Sanwu Du Tian Seal is closely related to the fifteen spiritual energy source, let alone looking for the six magical tools!"

Shangguan Xue and Kong Jue exclaimed, and they certainly did not expect that Nie Xin was going to find the six magical artifacts. They were shocked and said in unison: "Are you talking about the six magical artifacts?"
