In order not to be cut off, Li Xian decided to let the iron wolf squat at the entrance, and he and Xiaoqian broke into the Yang Qi factory.

Although the iron wolf was unwilling, he was also helpless, after all, among the three, his strength was the weakest.

Under the envious gaze of the iron wolf, Li Xian and Xiao Qian slowly flew along the cave wall towards the depths.

The cavern was at a forty-five degree angle, stretching underground, getting darker and darker, more humid, and thinner and thinner oxygen.

Fortunately, the half-ghosts needed yang energy, not oxygen, and darkness could not affect their eyesight.

After flying for about seven or eight minutes, they could only hear the roar of the water in front of them, and the two of them rushed over to see that there was an underground river in front of them.

The turbid and yellow underground river, the water is turbulent, and the undercurrent is surging, making people suspect that there are unknown monsters hidden in their hearts.

Because the cave goes all the way down, the underground river has completely submerged one of the caves, and in order to move forward, you must cross the underground river.

"No wonder it's called the Yellow Spring Passage! This water is yellow! Xiao Qian scolded and flew directly into the water.

"Oops!" She had just approached the main stream of the underground river when her body shook a little and she almost fell.

Li hurriedly flew up and grabbed Xiao Qian's hand.

Although their bodies are in a state of nothingness, their bodies do not produce resistance in the river, but because the river water passes directly through their bodies, it will still have a certain impact on them.

Li Xian's aura of the powerful heaven-level rune was completely unhindered, pulling Xiao Qian as if he were walking on the ground.

Schools of piranhas swam past them, and the two rows of piranhas' fangs shuddered.

"Fortunately, they can't see us, if we were human, how many lives would be confessed here!" Li Xian sighed.

"In recent years, human science and technology have become more and more developed, monitoring is everywhere, and if you want to open a large-scale yang gas factory in this information age, and it will not be discovered by human society, you can only do this!" Xiao Qian said expressionlessly, "I think that the yang gas factory where I was born back then was directly opened in the suburbs, raising pigs in the front and raising people in the back...... It's a pity that I burned the boss with a fire at that time, so I should have kept him and tortured him slowly-"

It was a casual chat, but as she spoke, Xiao Qian recalled the painful past, her voice became more and more sharp and fierce, her eyes were blazing, and she seemed to be spewing out the flame of revenge at any time.

A half-meter-long fat-headed catfish swam in front of Xiao Qian's eyes, and Xiao Qian, who was getting angry nowhere, suddenly opened her mouth and bit it on the neck.

The fat-headed catfish was bitten out of thin air, frightened and frightened, its body trembled violently, and the red blood spread in the turbid yellow water......

"Let's go." Li Xian gently pinched Xiaoqian's soft and slender hand, neither persuading her nor stopping her.

He is not a Tang monk, and he does not have the realm of "sweeping the floor without hurting the lives of ants, and cherishing the moth yarn lamp".

Xiaoqian let go of the fat-headed catfish in her mouth.

The bloodthirsty piranha moved when it heard the wind, and instantly surrounded the fat-headed catfish that was bitten by Xiao Qian, and bit it frantically.

Li Xian walked a few steps briskly, and finally crossed the underground river.

After crossing the underground river, the cave no longer moves downward, but at an angle of thirty or forty degrees, all the way up slowly.

The further you go, the wider the cave becomes.

At first, it was only one or two meters larger than the entrance, and the deeper you went, the larger the space, so that in the end, the cave was twenty or thirty meters wide and more than ten meters high.

And every fifty meters or so, there is a strange street lamp, which illuminates the surroundings exceptionally brightly.

The reason why I think the street lamp is strange is because it is completely different from what Li Xian sees in human society.

The street lamp is seven or eight meters high, and the cylindrical pole is extraordinarily thick, with a diameter of almost half a meter. The lampholder and glass lampshade on top are only slightly thicker than the pole, nearly two meters high, and are made of extremely thick bulletproof glass.

There was no electric light in the glass lampshade, only a strange large wick, crackling and burning.

"Do you know what kind of light this is?" Li Xian looked at Xiao Qian.

Xiaoqian's coquettish face became distorted and terrifying as if it had been greatly stimulated at this time: "Damn, I didn't expect that there would be a human street lamp now!" ”

"Human street lights?" When Li Xian was puzzled, he suddenly faintly heard a voice calling for help.

When he looked up, there was a soul in the glass shade of a street lamp beside him, desperately slapping the bulletproof glass, shouting sadly, "Let me out!" Help me......"

Li Xian stood on the ground a little on his toes, flew up in an instant, looked at it fixedly, and was taken aback.

It turned out that the "wick" turned out to be a human body!

When the soul saw that Li Xian had discovered him, he immediately danced excitedly: "Save me, save me, hurry-"

However, before he could finish speaking, the flame on the "wick" flickered, igniting the soul.

"Ahh

Faintly, it could be seen that the "wick" was now two legs, and then the feet were exposed, and when the feet were about to burn out, immediately another sick living person was pushed out of the lamp pole and quickly ignited.

"Ahhh

Before the word "help" could be uttered, the flames in his head had already burned him unconscious.

"These bastards!" Li Xian was furious and smashed his fist on the bulletproof glass lampshade, which was suddenly covered with cracks, but it was not broken.

"Brother Li Xian, they can't be saved." Xiao Qian hurriedly flew up and grabbed Li Xian, "These are sick humans. In order not to waste resources, Yang gas factories directly use them as fuel. The little sister who was in a cage with me back then, just because she had a cold, was stuffed into the human street lamp by them—"

At this time, the "wick" had been completely burned to death, and his soul, in a daze, was separated from the burning body, looked at his body in surprise, and suddenly shouted in horror: "Help, help—"

As he screamed, he slammed the lampshade desperately.

The glass lampshade had been cracked by Li Xian, and the soul's natal yang qi was a little stronger, almost breaking the glass lampshade.

"Can't let him escape, if he makes such a fuss, it will definitely alarm the people in the factory!" Xiaoqian said.

Spirits can't cross obstacles, but half-ghosts can.

Xiaoqian went directly through the bulletproof glass and entered the lampshade.

"Come, I'll get you out—" Xiaoqian said.

"Thank you, benefactor, you're such a nice man—" The soul wept with gratitude.

Taking advantage of his unpreparedness, Xiaoqian grabbed him by the neck and threw him onto his burning corpse.

His soul suddenly caught fire, and he scolded as he struggled: "You vicious little-"

has not finished scolding, and has been wiped out.

Xiao Qian flew out of the lampshade, looked at Li Xian with an ugly face, and explained: "His body has been burned, and he can't refine the Yuanyang Pill, and it's useless for his soul to escape." It makes no difference if he lives a few more days or a few days less - but he makes such a big noise, but it will affect us. ”
