"Huh?"

Lu Xingyue stopped abruptly and turned her head as if she had a feeling.

"Jiang Yao...... is Jiang Yao, is it you?"

The sound of Lu Xingyue's exploration echoed in the empty cavern, but there was no strange sound from the dark ahead.

Lu Xingyue watched for a moment, and finally sighed and withdrew her gaze from the front.

Since encountering a mutation in the Yongdao, Lu Xingyue and Jiang Yao both fell from the stone wall into the underground of the Yongdao. Lu Xingyue originally thought that he was in a catastrophe, but he accidentally fell into the underground river to save his life, but when he regained consciousness, he found himself alone in this long cave, and Jiang Yao's figure was nowhere to be found.

"That kid can't be so thin, right?tsk, if he does, it's going to be troublesome......" Lu Xingyue muttered, and then looked around the dimly lit cave.

The width of this cave is not large, but the length is not short. The winding front was dark, and in the faint light of the fireworks beads, you could see that the left and right rock walls were full of traces of erosion by the current, as if the hole should have been filled with underground rivers a long time ago, but now the dark river has shrunk greatly into a stream, and the water quality of this stream is also muddy, as if mixed with loess to show a muddy yellow-brown color.

The entire stream flowed slowly along the river in the front, I don't know where it flowed, and judging from the intricate forks and the dark environment before, even if Jiang Yao hadn't fallen to his death before, the chance of meeting with Lu Xingyue was quite slim.

Lu Xingyue pondered, lowered her head and gently rubbed the old Star Swirl Disk in her hand, fortunately it was not damaged by the previous disaster, and the trembling pointer still pointed to the front of the cavern, in the same direction as the stream. However, the biggest problem at the moment is not "direction", but "lighting".

Now except for the sparkling bead in his hand, there is only one left in his pocket, and there is not much time left to maintain the lighting, and once all the lighting is burned out, then there is only a dead end waiting for him.

"Everyone has their own fate, don't blame my brother, I left you alone......" Lu Xingyue muttered, the temperature in her eyes gradually turned cold, and finally settled into an indifferent decision. "Besides, I have 'must-do' things to do. ”

Lu Xingyue raised her head, then no longer hesitated, raised her feet and hurried in the direction of the stream.

"Smack...... Bang ......

A little bit of dew slowly dripped from the top of the cave, and with each step forward, the temperature in the cave seemed to be colder, and the surrounding rock wall gradually changed from a monotonous gray-brown color to a blue-black color, and a trace of crystal luster reflected from the surrounding rock wall, as if there was some different kind of mineral in this rock wall.

"This place...... It feels so weird......"

Lu Xingyue shook his head vigorously according to the accelerated heartbeat, the dull air made his mind a little dazed, and he quickly stopped, closed his eyes and silently recited the spell mantra, and finally returned to normal after a while. And when he opened his eyes again and was about to move forward, he suddenly found a space in front of him, and the sound of "whooshing" water came from in front of him, like a shallow beach where streams converge.

"Is there an exit ......?"

Lu Xingyue was overjoyed and hurriedly ran forward, but soon he noticed that something was wrong. I saw that under the fainter and fainter illumination of the fireworks beads, strange black oil paint lines appeared on both sides of the rock wall in front of me, extending all the way to the shallow space, and in the center of the closed shallow space in front of me, there was a broken black stone tablet, and the two large characters engraved on the stone tablet flashed with a strange glow in the darkness.

"Nine...... Quan ......" Lu Xingyue silently recited the big characters on the stone tablet, and her face changed suddenly. "Nine Springs?Could it be that this is the legendary 'Demon Cave' of the Netherworld...... 'Nine Springs Spring'?!"

Lu Xingyue was shocked, he was not unheard of the rumors of this 'demon cave' "going and not returning", and now he broke into this place by mistake, which can be described as extremely bad. However, what is worse is that at this time, the fireworks in his hand have burned to the last moment, and all that can maintain the light is the last straw in his pocket.

"Tsk, if you don't hurry up, you'll really die here......" Lu Xingyue took out the last of the fireworks bead from his pocket, and the pale orange light filled this vast shallow water again, but this time, Lu Xingyue keenly caught a black shadow in the rekindled light, flashing from the corner in front of him.

"Who!?"

[Hehe...... Hehehe......]

An eerie chuckle suddenly echoed in the vast space, exactly the same as what I had heard in the corridor before. Lu Xingyue's expression suddenly froze, and a pale yellow hook instantly set up a guard around him, but at this moment, a black shadow suddenly fell from the sky and rushed straight towards the top of Lu Xingyue's head!

"Pound!"

A dull crashing sound suddenly erupted in the sky above, and I saw a pale yellow strangulation mark on the black shadow's body, and then it was dragged by Lu Xingyue's light rope and flung fiercely towards the zenith of the cave.

"Playing sneak attack in front of Uncle Ben, you are too tender!" Lu Xingyue stared at the black shadow, the cold light flashed in the gold and silver eyes, and then waved his hand again, and the black shadow was dragged down from the zenith by the light rope, and plunged into the pile of rubble on the ground.

[Heh, hehe......]

I thought that the repeated attacks were enough to subdue the other party, but to Lu Xingyue's surprise, the black shadow not only showed no signs of retreating, but still sneered, crawled from the ground and slowly got up, and turned that miserable white face towards Lu Xingyue.

“…… Puppet undead!?" Lu Xingyue looked at the other party's pale mask that looked like a skeleton, and was shocked. I saw that the treacherous expression on the mask seemed to be smiling, and the chaotic body was wrapped in black mist, and with that weird laugh, the black mist gradually churned, and began to slowly spread along the entangled light rope towards Lu Xingyue's hand.

"Damn!" Lu Xingyue frowned, he had a lot of means to clean up the other party for people or demons, but for this kind of "undead puppet" that was already in the state of the undead, the existing means were obviously not enough. On the other hand, although the puppet undead attack methods are monotonous and involuntary, the black mist on their bodies is extremely corrosive, and once it is contaminated, it is not a joke.

But even so, it doesn't mean that Lu Xingyue will be helpless.

"Scatter!"

With Lu Xingyue's loud roar, the light ropes around the puppet undead suddenly scattered like star dust, and the puppet undead who had lost their restraint suddenly got up from the ground and roared again to pounce on Lu Xingyue, but before they could take a few steps, they suddenly froze. I saw that those star-like points of light began to seep into the puppet undead's body, and then converged into pale yellow light arrows, piercing out of the puppet undead's body!

"'Meteor Light Prison'!"

The arrows of light that burst out suddenly expanded, gradually converging into several spears, nailing the body of the puppet undead to the ground, and at the same time, one after another the same spears fell from the sky and pierced around the puppet undead, and a light prison was instantly cast, firmly binding the puppet undead in it.

【Roar——!!

The puppet undead struggled desperately again, but could not do anything but let out a roar of no sense. And Lu Xingyue didn't bother to pay attention to this "trapped beast in a cage" anymore, because at this time, he suddenly found that a dark hole appeared on the rock wall in front of him.

"There is no endless road, there is indeed an exit......" Seeing the three-person wide hole, Lu Xingyue's eyes suddenly lit up slightly, and then he left the roaring puppet undead, and cautiously leaned towards the entrance of the cave.

The light of the fireworks reflected faintly at the entrance of the cave, and the strange black oil paint lines on the rock wall also extended all the way into the cave, as if it had been taken in by something; in the faint light, he vaguely saw that there seemed to be a candlestick protrusion on the edge of the inner wall of the cave, and such a regular pattern could not have been formed naturally.

"This place...... How do you feel that there are traces of someone's activity......"

A vague uneasiness permeated Lu Xingyue's heart, and the closer he got closer, the more he felt a certain cold aura become more and more intense. He hesitated for a moment and stopped at the entrance of the cave, but at this moment, he heard a gust of wind whistling, and a stream of air with a fishy wind spurted out violently from the hole in front of him!

Lu Xingyue hurriedly turned his head away, raised his hand to block in front of him, and when the wind passed, he looked up at the cave again, but suddenly found that the "candlesticks" on the rock wall in the cave had ignited green phosphorus fires, and in Lu Xingyue's gold and silver eyes that were extremely sensitive to demonic energy, he also saw something "unusual things" at the bottom of the dim and vast cave.

A series of hanging figures hung their heads and hung sparsely from the top of the cave, swaying back and forth with the diffuse demonic wind, and beneath the figures who seemed to be hanged ghosts, a pool of black water with a thick fog was flowing quietly at the bottom of the cave, "gurgling" outward with ominous demonic energy.

"This breath...... Could it be the 'Soul Refining Pool'!?" Looking at the black pool of water at the bottom of the cave, Lu Xingyue's face changed suddenly, he quickly raised his head again, looked at those hanging figures, and found that those figures were all women, judging from the clothing, it seemed that they were the residents of the Nine Springs Walled City, but these women were pale at this time, their eyes were chaotic, and they seemed to be in a state of lack of souls.

"It turns out that the missing women in the city are all tied up here...... But...... What's going on in this state?" Lu Xingyue stared at the hellish picture in front of him in amazement, such a shocking situation that he even forgot for a moment that there was a puppet undead behind him who had unknowingly broken free from the light prison and was about to move.

【Roar——!!】

A gust of yin wind accompanied by a roar rushed straight into Lu Xingyue's back, Lu Xingyue suddenly came back to his senses, and reflexively waved the light rope in a hurry, trying to repeat the old trick again. However, this time, the puppet undead who was supposed to be unconscious seemed to have seen through Lu Xingyue's movements, and a dodge actually dodged the flying light cable, and quickly approached Lu Xingyue in an "S" shaped route.

"What!?" The unexpected situation caught Lu Xingyue off guard, but it was too late to dodge at this time. Seeing that the claws of the puppet undead were about to touch Lu Xingyue's face door, but at this moment, a loud bang suddenly erupted from the rock wall above Lu Xingyue's head!

"Boom!!"

A huge pile of falling rocks fell from the sky in an instant, burying the puppet undead in an instant, and Lu Xingyue was also completely knocked to the ground under this shock wave.

"Hmm...... cough, cough, cough!" Lu Xingyue covered his bleeding forehead, struggled to get up, and in the dust, he suddenly found that there was a familiar figure in front of him.

The messy black hair fluttered wantonly in the gusts of demonic wind, and the blood-red eyes flashed ominously in the darkness, and the demonic aura mixed with dark purple electric light wrapped around the figure, and along the figure's right hand, it transformed into a phantom of a giant claw. At this time, the man standing in front of Lu Xingyue had already lost his due rationality, but was filled with a strong anger.

"You, ...... you?" Lu Xingyue looked at the man standing on the pile of rocks, unbelievable.

"Jiang Yao!?"
