The air was filled with black smoke, and every black shadow let out a heart-wrenching roar. The originally invisible and intangible inner demons, at this moment, all turned into black smoke-like existences, and continuously launched wave after wave of attacks towards Xu Feng in the center of the open space.

At this time, Xu Feng's sea of ​​consciousness was already filled with heart demon beads. Because the Dragon Blood Shura Vine had devoured too many heart demons, the dark red scaly patterns on its surface slowly turned black. It looked like a plant growing in the devil's abyss, with its fangs and claws bared.

Even the Jingxin Yiqi Bell that was floating above the sea of ​​consciousness had cracks on its surface. The originally clear and loud sound of the bell now became dull, as if it would shatter at any moment.

The calamity power in Xu Feng's body, combined with the power of the inner demon, has reached its limit. The inner demon introduced into Xu Feng's body will be torn into pieces by the calamity power and can no longer be integrated in the slightest.

"The inner demon calamity has reached the final moment. I must find the last opportunity to truly overcome the inner demon calamity!" A hint of black air appeared between Xu Feng's brows. He had killed hundreds of inner demons, but now he was besieged by more inner demons. This made Xu Feng, who had been as calm as an ancient well, become a little anxious.

As if they had sensed something, the surrounding demons became more arrogant, surrounding Xu Feng unscrupulously and spying on him constantly. As long as they found a crack in Xu Feng's mind, they would rush over, tear Xu Feng's soul into pieces and then eat them.

"Opportunity, where is the opportunity?" Xu Feng frowned slightly, expanded his spiritual sense, and carefully observed every revealed inner demon.

In his opinion, among so many inner demons, there must be a leader-level one. If he wants to survive the inner demon calamity, the final chance will definitely fall on this leader-level inner demon.

But after observing for a long time, he did not find any of the inner demons showing any abnormality.

There are two ways to increase the power of "Wanjie Moshen Gong". One is to overcome the tribulation, and the other is to integrate it into the full-level skills.

The fusion of full-level skills is inefficient, time-consuming, and requires painstaking effort, but it is safe and will not cause harm. The tribulation is efficient, fast, and takes a short time, but it is extremely dangerous. If you are not careful, you will die.

Especially when looking for the last opportunity, if you don’t understand what the last opportunity is, there will be only one outcome.

Seeing more and more inner demons gathering, Xu Feng became more and more irritated, and even his eyes slowly became bloodshot.

"Since I can't find you, I'll kill you all!" Xu Feng let out a low roar, and a huge Shura vine appeared behind him. This was the shadow of the Dragon Blood Shura Vine. The dark red dragon scale patterns on the surface were mostly black with less red. It looked like a hell plant that was completely black with just some red stripes.

Crack~ A crisp sound rang out in the sea of ​​consciousness, and the magic-grade meditation bell shattered into pieces. The fragments turned into clear air and dissipated in the sea of ​​consciousness.

The Jingxin Yiqi Bell shattered, and the fragments turned into pure air and dissipated in the sea of ​​consciousness, allowing Xu Feng to regain clarity of mind. His originally irritable mood also calmed down instantly.

As soon as he thought of it, three black and gray swords with a metallic luster suddenly appeared out of thin air, surrounded Xu Feng and started to kill people non-stop.

The smoke that was constantly spinning around Xu Feng would immediately let out a shrill scream and turn into ashes when hit by the three long swords.

The Concentrated Mind Demon Slayer Sword! Moreover, it was a Concentrated Mind Demon Slayer Sword that had been cultivated to the state of great perfection, and it had also been integrated with the Tribulation Force, making it a Concentrated Mind Demon Slayer Sword that was completely condensed by the Tribulation Force!

All the inner demons were unable to withstand the force of the Heart Sword and turned into ashes one after another. The inner demon beads fell to the ground one by one. In just a few minutes, hundreds of inner demon beads were scattered on the ground.

Puff, puff, puff~ The vines of the Shura vine, like spears, pierced through the surrounding black smoke. At this moment, Xu Feng was like a ruthless machine, slaughtering all the demons around him.

At this time, Princess Su Yue of the Great Yan Dynasty was floating above Chang'an County, stepping on the flying sword blankly. She watched the three flying swords flying up and down beside Xu Feng. The huge Shura vine behind him covered the sky and slaughtered all the besieging demons, turning them into demon beads.

Princess Su Yue had never thought that there would be so many demons in Chang'an County. If she had known there were so many demons, she probably would not have dared to come explore alone.

She had never imagined that the Holy Son of Wanfa Sect was so powerful. It seemed that the inner demons were besieging him, but in fact he completely crushed them. No matter how many there were, they were no match for him.

"Is this the strength of the Holy Son of the Upper Sect?" Princess Su Yue murmured.

After a while, the surroundings became quiet again. Only Xu Feng looked unhappy. He still hadn't found the last chance to defeat the inner demon. The phantom of the Shura vine behind him, with forty-eight auxiliary vines spreading wantonly, looked like evil dragons, raising their heads and roaring silently.

Xu Feng was breathing heavily, and with a thought, he put all the Heart Demon Beads that remained in his sea of ​​consciousness and fell on the ground into the space package. There were more than 370 Heart Demon Beads in total. Even if he returned to the sect, he could exchange them for a considerable amount of contribution points.

"Princess Su Yue of the Great Yan Dynasty pays homage to the Holy Son of the Wanfa Sect!" When Princess Su Yue saw the end of the battle, she quickly controlled the flying sword to land and saluted with a fist.

At this time, Xu Feng's clear and bright state, which had been restored by pure energy after the Jingxin Yiqi Bell shattered, slowly disappeared. All his inner demons had been killed, but he still hadn't found the final opportunity, and hadn't overcome the calamity of his inner demons.

"The demonic disaster here has been eliminated, and all the inner demons have been killed by me!" Xu Feng said impatiently, waving his hand.

"Fairy Envoy, the fact that so many inner demons can appear in Chang'an County means there must be a passage to the inner demon world nearby. If this passage is not sealed, inner demons will appear again nearby!" Princess Su Yue said hurriedly.

"The passage to the world of inner demons?" Xu Feng's heart moved, and an idea flashed in his mind. The last chance for him to survive the calamity of the inner demons might be this passage to the world of inner demons.

"Where is the passage to the inner demon world?" Xu Feng asked.

"There are so many inner demons here, they must be nearby, maybe even in Chang'an County!" said Princess Su Yue.

Unexpectedly, a passage to the world of inner demons appeared in the territory of Dayan, which made Princess Suyue nervous. The inner demons were invisible and intangible, and extremely strange. Only the Holy Son of Wanfa Sect had such strength to kill hundreds of inner demons in one breath. If it were anyone else, hundreds of inner demons would be enough to destroy any large city with a population of millions in the territory of Dayan.

Xu Feng's perception expanded, integrating the calamity power with the power of the inner demon. He was very sensitive to the fluctuations of the power of the inner demon. A quarter of an hour later, Xu Feng came to a three-story building.

This is a very ordinary small building, built entirely of bricks, stones and wood. At this time, the whole building was split into two, and a huge crack appeared in the middle.

What is strange is that the small building, which had clearly been split into two, did not collapse. Instead, it was in a strange state, as if time had stopped at the moment the small building split, and its state just after the split was completely preserved.

Seeing the space crack in front of her that was more than ten feet long, Princess Su Yue showed a look of despair on her face.

There is no wrong version in the 1619 book forum!

"Is this, is this God's will to destroy Dayan?" Princess Su Yue murmured to herself.

This space crack is so big that in order to seal it completely, at least several formation masters are needed, and countless precious sealing materials are needed to seal it. But now, there are only her and Xu Feng. Even if they find the passage to the Heart Demon Realm, they are helpless.

At this moment, a gust of wind swept in from the space crack of more than ten feet in front of them, accompanied by a heart-wrenching roar, making people feel as if countless demons and monsters were hidden in this gust of wind.

"Heart, inner demon!" Princess Su Yue's face changed drastically and she couldn't help but scream.

She knew that the more afraid she was, the more likely it was that these inner demons would see through her weaknesses. But fear did not mean she could stop being afraid just because she wanted to.

Su Yue's legs went weak and her face was filled with fear. She wanted to summon a flying sword to escape from here, but her mind was so shaken that she couldn't control the flying sword at all.

With a buzzing sound of sharp blades, three black and gray swords suddenly appeared beside Xu Feng. The swords had a metallic luster, but they were different from ordinary steel materials and had a vague sense of transparency.

Concentrate on the Demon-Slaying Sword! As Xu Feng unleashed his three heart swords, they immediately flew up and down around Xu Feng.

At this time, Xu Feng was standing in front of this huge space crack, and with his own strength, he was resisting the countless demons flying out of the space crack.

A shadow of a Shura vine over ten feet long suddenly appeared behind him. Each vine was as thick as a bucket, and it was waving freely in the air like a giant python.

Puff, puff, puff~ The Shura Vine penetrated more than ten balls of black smoke in a row. With a light twist, more than ten heart demons were instantly crushed to pieces and turned into heart demon beads that fell to the ground.

Xu Feng killed dozens of inner demons again, but he still couldn't get over the inner demon calamity.

"This, this crack is still getting bigger!" Princess Su Yue on the side seemed to have noticed something. She pointed at the crack in space with a look of fear on her face.

The crack, which was originally only ten feet high, suddenly spread dozens of meters in all directions. There was a lake in the crack, emitting strange fluctuations, and countless black air emerged from the crack.

"As long as this crack exists, a huge number of inner demon monsters will emerge every once in a while!" Xu Feng frowned slightly. Faced with such a huge space gap, he had no way to seal it for a while.

"It's too passive to stay here all the time. I don't have that much time to stay here all the time!" Xu Feng narrowed his eyes, a gleam of light flashed in his eyes, and he quickly made a decision! Go in!

Enter the Heart Demon Realm from this gap! Xu Feng had a hunch that the last chance he needed should be in the Heart Demon Realm. Standing here, he would never be able to survive the Heart Demon Tribulation! ...
