The arc of the blue thorn made Ai Hui immediately regain his long-lost strength. He had been refining his body in the thunder for a long time, and the thunder was too familiar to him. When the thunder and lightning released by the blue thorns entered the body, countless insights suddenly came, like a spring.

This wonderful world is unusually friendly to thunder.

What's even more amazing is that the thunder and his ghost sword are unusually compatible, probably neither of them is within the Five Elements? Ai Hui has not yet figured out the mystery.

The ghost sword is also gradually undergoing significant changes, and the original attributes of yin and yang have become more and more prominent, and the boundaries are clear. The Yang Sword gradually turned pure white, and the fine thunder traveled in the body of the sword, making them look like they were dressed in silver silk clothes, which was extremely dazzling. The Yin Sword gradually turned black, and the thunder on the sword body also seemed to be dyed black, as if countless shadows were wandering, as if a layer of black mist was shrouded in the sword body.

Black Thunder?

Could it be Yin Thunder? Ai Hui thought of what he had read in the Xiuzhen classics. It is said that the yang thunder is fierce and can break all evils, while the yin thunder is vicious, such as the gangrene of the bones.

At that time, he read the Xiuzhen classics, but he just regarded them as stories and readings of gods and monsters, and he didn't expect that he would use them one day. The Ancient Thunder Recipe is broad and profound, and it is a big category, but unfortunately it has long been lost.

When the book is used, it is less hated, and this sentence can probably be used at any time.

Thunder was affected by the ghost sword, and the yin and yang appeared, which surprised Ai Hui.

This means that between Thunder and Ghost Sword, Ghost Sword is dominant. Thunder was almost the most powerful force in Ai Hui's impression, but now he found that the ghost sword he cultivated could actually gain the upper hand.

It turns out that the sword cultivator who cultivated the ghost sword can dominate one side, it's not a rumor.

Ai Hui couldn't help but be happy in his heart, but then he smiled bitterly, okay, let's go out from this ghost place first.

There are evil sects everywhere here, and he doesn't dare to be careless. If he hadn't been careful enough, he would have died many times.

Ai Hui stopped.

In front of him, a vast swamp with no end in sight.

The swamp was full of gray mud, and clumps of dark green meadows like steel needles were scattered here and there. A faint gray mist emerged from the mud and gradually coalesced into a cloud of mist. The air currents in the fog tumbled and flowed, vaguely like distorted and blurred human faces. Whimpering sounded like a cry and drifted out of the fog, making the swamp even more bleak and cold.

When Ai Hui appeared at the edge of the swamp, all the floating mist faces on the swamp turned towards him in unison.

I don't know if it's an illusion, Ai Hui felt that those faces were smiling at him.

"Come on...... Come on......"

"Bah...... Yikes......"

"Hee-hee-hee......"

The shrill sound fluttered in the wind, like a tightrope piercing the eardrum. The sound is extremely uncomfortable, but it has a strange magic that makes people want to listen more carefully.

Rao is Ai Hui is bold, and in the face of this situation, he couldn't help but shudder. An inexplicable chill penetrated into the bones.

But for some reason, the eerie swamp in front of him attracted Ai Hui deeply. It's like a voice in his heart saying, "Get in, get in."

Ai Hui froze, he took a few steps back, his eyes clear.

In the swamp of human faces, there is a power that can influence people's minds.

The Human-Face Swamp, the name he had just given to this gray swamp, was an extremely dangerous place.

Ai Hui decided to take a different path, and he began to move along the edge of the swamp of human faces. As soon as he moved, the mistmass floating in the swamp turned in unison, staring at him all the time.

Ai Hui pretended to turn a blind eye, but the hairs on his back stood up involuntarily.

The scene he witnessed later confirmed the danger of the swamp.

At that time, a cloud of algae chased a group of plants, and as a result, the panicked plants broke into the swamp. And Ai Hui, who felt almost invincible, actually stopped at the edge of the swamp. And those plants that broke into the swamp were immediately surrounded by a foggy human face. The vivid and bright colors fade quickly from the branches of the plants, turning a dull grayish. The branches that were as hard as iron began to soften and melt, and large patches of mud fell from the branches.

The gray mud and the swamp merged, and all the fog and human faces dispersed.

Strange shrill laughter enveloped the swamp again.

Ai Hui swallowed, his face pale, he finally knew where the mud came from.

In the vast swamp, there is no end in sight to the gray mud, how many plants are buried here?

He didn't dare to imagine.

Where is this human-faced swamp, this is the real swamp of death.

Ai Hui once again sensed a faint wisp of consciousness cast from the depths of the sky, and "it" was paying attention to what was happening below. Ai Hui didn't look up, now he wasn't in the mood to care about that high-altitude existence.

He moved laterally along the swamp, trying to find a way around it. However, what he didn't expect was that the human face swamp was even more vast than he expected. Wherever he went, the fog man's face would turn neatly, staring at him. At first, Ai Hui felt like a mang on his back, and he didn't feel anything after a long time.

Well?

The corners of his eyes suddenly shrank, and the ground not far ahead was scattered.

He remembered very well that it was the traces left by the plants that had broken into the swamp before when they fled for their lives. I obviously walked along the edge of the swamp in one direction, how did I walk back?

Could it be that the swamp is round?

Ai Hui shook his head, denying the speculation. He had an excellent sense of direction, and he could be sure that he was going straight.

There are quirks.

A shrill laugh came from the swamp, and the mist looked at Ai Hui with a face, as if mocking him for his futility.

After listening to it too much, Ai Hui was indifferent to the laughter of the foggy human face.

Is it a fantasy?

What to do?

The detour has been proven impossible, and there are not many roads in front of Ai Hui, either forward or backward. He shook his head, the place where he woke up was barren and empty, and now he was encountering more and more things, more and more lively.

He was heading towards the center, though the path ahead had become more dangerous.

Opportunity is always hidden in danger.

Ai Hui had a hunch that if he wanted to leave this strange place, the opportunity must be in a more dangerous and lively front, not a desolate and desolate marginal area.

Ai Hui decided to move on, which meant he had to make his way through the swamp.

It's a pity that you can't fly, otherwise it would be a good idea to fly high above the swamp. The inability to fly has caused problems more than once, and about the problem of flying, he already has a rough idea, but unfortunately there are no conditions to realize it yet.

Ai Hui decided to test the face swamp first.

A ghost sword around him flew out and turned into a silver light, shooting towards the face of the mist closest to Ai Hui.

The silver sword rayed into the mist's face, and it pierced out effortlessly, drawing an arc back to Ai Hui's side.

The constantly distorting fog froze abruptly, and in the center of the face, there was a little more silver light.

Countless tiny arcs of lightning exploded from the silver light, instantly covering the entire misty face.

A terrible howl suddenly sounded, and the face of the fog shrouded in thunder disappeared without a trace.

Although Ai Hui didn't know what the mist face was, he always felt that it was a yin and evil thing, so he chose the Yang Reggae Sword. It turns out that Yang Lei has a lethal effect on the face of the fog ball.

But Ai Hui didn't have any joy on his face, he stretched out his palm, and the Yang Thunder Ghost Sword that flew out just now fell into his palm.

The yang thunder of the sword body was much dimmer.

The number of ghost swords he had now increased from before, to thirty-two. But glancing at the endless swamp, Ai Hui couldn't help but shake his head. Thirty-two ghost swords, sixteen Yang Thunder Ghost Swords, absolutely unable to support themselves out of the swamp.

The Yang Reggae Sword alone was not feasible, and Ai Hui decided to try the Yin Reggae Sword.

The ink-black Yin Thunder Ghost Sword flashed in the air, as if cutting through the space, leaving a gap leading to the void. The Yin Thunder Ghost Sword also pierced through the mist's face effortlessly, but the results were completely different.

A small wisp of black gas appeared on the gray mist's face, and in the blink of an eye, the mist's face was shrouded in spiderweb-like black lines.

The distorted mist face became more distorted, and a low, tearing roar came from the mist face, and the gray mist face almost turned black.

It slammed into the face of a foggy figure not far away.

A low, tearing roar and a shrill and eerie howl mingled together, and the black and gray faces were frantically gnawing at each other. The other gray mists turned their faces abruptly, and the screams of the swamp swarmed up, encircling the black faces. In the blink of an eye, the black mist human face was eaten away.

The madness of the scene made Ai Hui's heart a little hairy.

The effect of the Yin Thunder Ghost Sword was not what he expected, but he was keenly aware that there might be something to use in it.

The Yin Thunder Ghost Sword that had just made a contribution fell back into his palm, and sure enough, the Yin Thunder on the sword body was a little thinner.

It seemed impossible to rely on the power of the ghost sword to break through directly, and he had to come up with a feasible way.

Ai Hui also noticed a different detail than before.

In the past, he hunted all kinds of plants, leaving behind the essence. It was the essence of these plants that allowed Ai Hui's ghost sword to grow to the point it is today. However, two clouds of mist in a row were wiped out, and they completely disappeared, leaving nothing behind.

The absence of loot was certainly unpleasant, but Ai Hui didn't care too much at this time, what caught his attention was the message behind it. Whether it was a swamp or a foggy face, they were a different kind of existence than the strange plants he had encountered before.

Algae is much more powerful than normal plants, but it is no different from what it hunts.

How can I get through the swamp?

Ai Hui's gaze suddenly fell on the meadows scattered in the swamp, and his heart moved.

Why did these dark green meadows, which looked like a ball of steel needles, survive in the swamp and not turn into a mess of mud?

Don't...... What's so special about these ordinary-looking meadows?

His heart moved, and a ghost sword around him flew out.

The sword flashed in the air and flew towards the meadow.

Seeing that the sword was about to hit the meadow, the shock suddenly happened!
