Immediately, Ling Feng was about to exchange for a seventh-order holy weapon, when suddenly a heaven-shaking dragon roar came, and the power was shocking, and the entire Cuiyun Building trembled.

He secretly said in his heart: "What's wrong, how can there be such a powerful dragon groan?"

At this time, Qin Yuyao hurriedly came upstairs and said, "Hurry up, there is a powerful evil dragon attacking Luzhou City, let's go quickly, if it is too late, we will be buried in the dragon's mouth." ”

"What the hell, there are dragons attacking the city for some reason?"

Ling Feng secretly wondered in his heart, shook his head and said, "I'll take a look!"

After he finished speaking, he jumped out of the Cuiyun Tower from the window, suspended the sky with the Jindan force field, and sure enough, he saw a huge black dragon with a length of thousands of meters hovering in the sky, spitting black dragon flames everywhere, destroying everything. I don't know how many people were wiped out in an instant in the black dragon flame.

Many people in the city are rushing to flee, many people who are injured and unable to run are screaming in panic, and the whole world presents a scene of annihilation.

Ling Feng saw that his anger rose, and he immediately drew his sword out of its sheath, condensing the Chaos Sword intent into the Chaos True Dragon Sword in his hand, and slashed out a huge Chaos River, attacking the black dragon.

A long and narrow wound appeared on the black dragon's body, and he immediately looked at Ling Feng, and a tear suddenly dripped from the huge dragon's eyes, and his expression was extremely sad.

When Ling Feng saw this look, a heart-wrenching emotion inexplicably appeared in his heart, which was a manifestation of heart-to-heart connection. He was immediately alert, condensed the Void Heavenly Eye, and looked at the Chaos True Dragon Sword in his hand, but found that the sword body was extremely black, and there were black tentacles at the hilt of the sword invading his own arm, absorbing his own power. And he is not in a physical state at this time, but a divine soul state, and there are also many black demonic qi eroding his divine soul. These demonic qi contain chaotic and evil demonic thoughts, but they are the demonic qi mentioned in the Heart Demon Secret Text.

"It's not good, Heart Demon Fantasy Realm! I've encountered the Heart Demon Tribulation now!"

Ling Feng reacted quickly. Immediately urged the Divine Soul True Fire, and the gray-white Chaos True Fire appeared all over his body, quickly refining the demonic qi.

He looked at the world-destroying black dragon again, where was the black dragon, it was clearly the true dragon primordial god of the Chaos True Dragon Sword. And those so-called people are clearly demonic illusions, and even the whole world is illusory, just the illusion of demonic energy. Obviously, at the time of his tribulation, the demons of his heart quietly invaded at some point. What happened to him after that was actually a demonic illusion of the heart.

Seeing that Ling Feng's expression had regained consciousness, the True Dragon Yuan God was immediately overjoyed, and let out a dragon groan, continuing to spit out dragon flames and destroy this Heart Demon Realm.

At this time, the figure of 'Qin Yuyao' shot out from the burst and said with a smile: "Lin Feng, you can't run away!"

After she finished speaking, her entire body melted into black demonic qi, and the entire world began to destroy and collapse, reverting to black demonic qi, constantly compressing inward. The strength of this demonic qi has reached the peak level of Wuzun, even the true dragon primordial god can only condense the Chaos Dragon Flame to refine the demonic qi, and it is difficult to break through for the time being.

And Ling Feng also condensed the Chaos True Fire to refine the Qi of the Heart Demon, but soon found that the power of his Divine Soul was far inferior to that of his heyday, and he should now only be a part of the Divine Soul containing the main consciousness, and was quietly dragged into the Mental Demon Fantasy Realm by the Inner Demon. In this case, he played a limited role.

At this time, in the vast and boundless Chaos Bead space, a huge black demonic qi with a radius of a hundred miles was constantly collapsing.

At this moment, the Chaos Yuan Spirit Bead and the True Dragon Battle Armor, the two sixth-order high-grade divine weapons of war, suddenly appeared in the Chaos Bead, and a hundred-foot-long Soul Devouring King Worm and a hundred-foot-long Chaos True Dragon rushed towards the black demonic qi. The Soul Eater King Worm quickly devoured and refined the demonic qi, this demonic qi contained the mind of the demon, and if you were not careful, it would invade the divine soul, which was very difficult. Ordinary martial arts powerhouses don't dare to refine it easily, but the Soul Eater King Worm has the talent of soul devouring, but he is not afraid at all, and instead treats the demonic qi of his heart as a delicacy.

And the True Dragon Weapon Spirit of the True Dragon Battle Armor was originally evolved from the Yan Dragon Dragon Soul, and it was the best at Dragon Yan, and it was not afraid of the Qi of the Heart Demons at all, and it was rapidly devouring and refining the Qi of the Heart Demons.

With the internal and external attacks, this powerful heart demon at the peak level of Martial Venerable was quickly unable to resist, and Ling Feng fused with the True Dragon Yuan Shen, taking the opportunity to rush out of the inner space of the heart demon.

Ling Feng returned to the Chaos Bead, and immediately completely restored the Divine Soul cultivation in the later stage of Wuzun, he immediately used three thousand Chaos Sword Fetuses to urge the Chaos Sword Array, blocking the Chaos Bead space, preventing the heart demon from escaping, and then the mind and the True Dragon Yuan God fused, consuming a large amount of the power of the True Dragon Yuan God, condensing the Chaos Law and Chaos Sword Intent, and suddenly slashing out a chaotic long river, sweeping towards the Heart Demon.

The inner demon also suddenly condensed his mana, exerted his magical powers, and evolved a black river to attack.

However, Ling Feng urged with all his strength this time, and he instantly consumed one-sixth of the origin of the True Dragon Yuan Shen, and his power had already surpassed that of ordinary martial arts peak powerhouses, and the heart demon suffered a heavy blow in an instant.

Immediately, the Soul Eater King Worm and the True Dragon Battle Armor Weapon Spirit simultaneously exerted their might, taking the opportunity to devour a large amount of demonic qi, and then left.

These two are big stomach kings, and they each devoured nearly a quarter of the heart demon's heart demon's qi. At this time, the cultivation of the Heart Demon was almost halved, and he was suddenly powerless to resist the alliance of Ling Feng and the True Dragon Yuan Shen, and was soon sealed and refined by Ling Feng, as the foundation for the promotion of the Heart Demon Secret Book to the fifth layer.

......

At this time, the outside world.

Ling Feng stood in the ring, and Chu Lingyue guarded Ling Feng with a sword.

Not far away, Governor Pei Mingyuan, Jiang Yangming, the head catcher of the Six Gates, and the elders of the Four Great Sects looked at Ling Feng with their eyes flickering. Especially the Martial King Elder of the Flame Sun Sword Sect, staring at the Chaos True Dragon Sword on Ling Feng's waist with a greedy expression, he had just seen the vast power of the Divine Sword in Ling Feng's hand to resist the Heavenly Tribulation. If he could capture this sword, even if he was a martial arts powerhouse, he could easily kill him.

However, they didn't move lightly, not because of Chu Lingyue. Instead, he was worried about the Divine Weapon Armor on Ling Feng's body. At that time, not only did they not get any benefits, but they might have awakened Ling Feng, who was experiencing the Demon Tribulation.

And Chu Lingyue was also a little apprehensive at this time, she was guarding Ling Feng not because of how loyal she was, but because the fate of the two of them had now been connected. If Ling Feng suffers, as Ling Feng's 'sister', he will inevitably not be able to escape the poisonous hands of those greedy people. However, she knew that the current stalemate would not last long, and if Ling Feng didn't wake up again, those people might not be able to help but make a move.

At this moment, a cloud of red sword light came rapidly from the sky, condensing into a middle-aged man holding a red long knife with a majestic and domineering expression.

Pei Mingyuan looked at this person, his face suddenly changed, and he said, "Yanyang Sword Venerable!"

Yanyang Sword Venerable is the founding ancestor of the Yanyang Sword Sect, and he is the cultivation of the Yuan Shen Dharma Body in the late stage of Wuzun, and his strength is higher than him. If this person can come so quickly, it must be someone from the Burning Sun Sword Sect who has sent a message. He secretly said in his heart, and let the Yanyang Daozun test it, if this person really couldn't save his life from the Heart Demon Tribulation, he wouldn't mind taking the opportunity to get a piece of the pie. On the contrary, if this person can wake up, he will take the opportunity to help and form a good relationship.

The Flame Sun Sword Venerable quickly locked onto Ling Feng, who was standing in the ring, and the Yuan Shen mana condensed into a big red hand and grabbed it.
