At this time, Lu You regretted a little that he chose to upgrade the Thunderbolt software, otherwise, how good would it be to call and ask?

However, there is no regret in this world, in the dark and empty passage, there is no concept of time at all, Lu You unfolded the stunt of flying on the grass without a trace along the way, 'meeting the mountains and mountains, meeting the sea and crossing the sea', along the way, most of the things I saw were extremely miserable scenes framed by the organs.

Whether it is the students of the Dragon's Tooth Tower, or the invaders from all over the world, they have been tortured by the insidious mechanism in this underground passage*, I don't know how many people, buried in the ground forever, accompanied by the loess, and finally turned into a skeleton.

Time passed slowly, and I don't know how long it took, Lu You was tired of running, and the true qi in his body was seriously consumed, so he had to find a relatively safe place and took out a jade bottle from his arms, which contained the Mixed Yuan Qi Gathering Pill.

Fortunately, he has experienced a lot of disasters and has long been accustomed to making double preparations, otherwise, in the case of the mobile phone cannot be used, the environment here will undoubtedly be worse.

There are no years of cultivation, I don't know how long it has been, Lu You, who is in recovery, suddenly feels a rapid footstep running in his direction, although the true qi in his body has not yet recovered to the peak, but Lu You has no choice but to quickly stop the operation of the exercises, the muscles of his whole body are tense, and he is quietly on guard.

Sure enough, the footsteps were getting closer and closer, and there was a faint purple true qi entanglement between Lu You's fingers, once an enemy came in, he would not hesitate to use the thunder method to kill the other party.

In the depths of this dimly and gloomy passage, everyone must not only be careful of the terrible traps here, but also be careful of the opponent killing opportunities that come everywhere, and many times, although you dodge the traps, you may be planted under the knives of others.

After all, in this passage, there are cultivators and supernatural people from all over the world, each of whom should not be underestimated, and killing someone for the sake of profit is like killing a chicken.

At this moment, the place where Lu You is located is a collapsed place in the passage, perhaps due to old disrepair and lack of maintenance, and the stone wall of the passage has collapsed in some places, which is a natural hiding point.

However, this collapse is not deep, and as long as someone looks closely, it can still be found.

Time passed minute by minute, the sound of hurried footsteps outside was getting closer and closer, and suddenly, the black shadow outside flickered, and the figure swept by quickly, not noticing the collapsed place, let alone Lu You.

This scene made Lu You's tense mind a little relieved, but at this moment, suddenly, the black shadow that had gone away suddenly turned back again, dodged, and entered the collapsed place, accompanied by a strong smell of blood.

The purple light that had just dispersed between Lu You's fingers resurfaced again, and the torrential rain and thunder slapped directly on the chest of the person who came, and the wind was sharp.

"Yikes!!"

The people who came didn't seem to expect that there were still people hiding in this collapsed place, and they couldn't help but let out a low cry and secretly said: God will kill me!

"Sister Long?"

But at this moment, Lu You's half-swung fist suddenly stopped, and he looked at the figure in front of him in a daze, and the person who came was Long Xue, who they had been looking for for many days and had not seen for many days.

Lu ...... Land tour?"

The same incredible voice came out of Long Xue's mouth, obviously she didn't expect to meet Lu You here, the strong killing intent at the moment when Lu You made a move just now made her feel like she was dead.

"Sister Long, where are you from, we have been looking for you for a long time, how can we find ......?"

"Shhhh

Lu You was only halfway through his words, when he was suddenly interrupted by Long Xue, his pale face was full of fear, and he leaned against the wall.

Although Lu You was puzzled, he immediately realized the seriousness of the matter when he looked at Long Xue's embarrassed posture covered in blood and the panic that was difficult to hide.

At the same time, he suddenly felt the temperature in the entire passage plummet, and an eerie chill swept over the world, it was a kind of cold that made people feel from the depths of their souls, as if they were going to freeze people's souls.

"This breath is terrifying!"

Lu You's heart was shocked, and his nerves were tense, and as for Long Xue beside him, he had already reined in the aura of his whole body, and completely fell into a kind of dead silence, like the legendary Turtle Breath Dafa.

In the dead silence, the cold breath outside the passage became heavier and heavier, Lu You felt a burst of pain like a pinprick coming from the depths of his soul, and he couldn't help but immediately turn on the real fire in his body, and in an instant, the flames in the dantian burned, and the hot breath went straight to the brain, and his body felt a little better.

But at this moment, Lu You's eyes shrank suddenly, and he saw that outside the collapsed cave entrance where they were hiding, a pair of huge eyes suddenly appeared, and those green and cold eyes stared straight at the two of them.

"Damn, it's been discovered! this beast has terrible perception!"

Lu You raised his eyebrows, and the next moment, his whole body was wrapped in purple gas, and a thunderous punch blasted out!

Rumble!

The fist containing infinite power surged out, however, it was directly and flexibly dodged by the beast, Lu You looked serious and flew out, since it had been discovered, it could only be more dangerous to hide inside.

At the moment when he flew out, Lu You finally saw the appearance of the beast in front of him, and couldn't help but let out an exclamation: "Fierce spirit!"

That's right, what appeared in front of Lu You's eyes at this moment was a fierce spirit, however, the strength of this fierce spirit didn't know how many times stronger than the fierce spirit that Lu You had killed every day in the dragon's tooth town before, and his breath was as majestic as the sea.

Except for the iconic body, which is more illusory, the rest of the body is almost the same as a real beast, this fierce spirit has the head of a lion, the body of a bull, wings on its back, and claws like eagle's claws.

Under the gaze of Lu You's discerning spiritual eye, the battle value floating above the head of this fierce spirit turned out to be an astonishing 200,000!

No wonder Long Xue was so seriously injured, so frightened, and so terrifying in battle, he was simply a strong man in the early stage of Jindan, and he was the kind with a stable realm.

"Lu You, be careful! This beast's attribute is a mutated ice attribute!"

At the entrance of the cave, Long Xue let out a low cry with a pale face, her body has suffered a serious blow now, and the blood veins all over her body are almost frozen, if she goes up, not only will she not be able to help Lu You, but I am afraid it will be a burden.

Lu You nodded, took out the jade bottle containing the Mixed Qi Gathering Pill from his arms, threw it to Long Xue, and said coldly: "Swallow it quickly and recover your strength!"

Long Xue knew the seriousness of the matter very well, and when she heard this, she immediately opened the jade bottle, quickly poured out a handful of Mixed Yuan Qi Gathering Pill, and swallowed it in one gulp.

Rumble!

As soon as the Mixed Yuan Qi Gathering Pill entered the body, a terrifying energy suddenly erupted, and that powerful energy made Long Xue, who was caught off guard, directly spit out a large mouthful of scarlet blood, and there were ice slags in the bloodstains.

"This ...... What kind of elixir is this?

Long Xue looked shocked, she always thought it was an ordinary pill, so she swallowed it directly without hesitation, but she didn't expect that the injury was not cured, but it made it worse.

In the passage, Lu You, who was confronting the fierce spirit, saw this, the corners of his mouth twitched slightly, but he didn't say much, all his thoughts at the moment were focused on the terrifying fierce spirit in front of him.

Call!

The cold wind howled, and the fierce spirit opened its mouth to spew out a terrible ice mist, and where it passed, a thick layer of ice immediately formed on the ground, and in the passage, huge rocks directly split and turned into a pile of residue, obviously unable to withstand the terrible cold.

Lu You's whole body was full of flames, and in the face of the terrifying fierce spirit in front of him with a combat value of 200,000, he didn't dare to play like before, and the pig-killing knife in his hand burst out with sharp flame knives and swept out.

Rumble!

The flame knife and the ice mist collided in mid-air, and immediately erupted into a piercing sound, since ancient times, water and fire are incompatible, ice is a mutant of water attributes, but it still belongs to water, and the two sides are almost natural rivals.

After a violent entanglement, the sword rays emitted by Lu You gradually occupied the below, and the terrifying ice mist swept in again.

"Boning knife method!"

Lu You was not the slightest surprise at this, his face was calm when he saw this, but his heart was full of anger, and a fierce anger ignited, and the pig-killing knife in his hand was twisted flexibly, and his body moved with his heart, and the knife moved with him, at the same time, the calm true qi in his body began to boil, and the pig-killing knife in his hand made a piercing knife sound.

Half a year ago, when Li Hu taught him the boning knife technique, he once said that his knife is also called the knife of rage, the more angry he is in his heart, the stronger the knife technique he casts, the faster he can kill!

When the anger reaches a certain level, the speed of the knife exceeds the wind, the sound of transcendence, breaking through the limit, that knife goes down, the enemy is not dead and disabled, this is the true essence of the boning knife!

Although Lu You's current knife technique has not yet achieved the requirements of Li Hu beyond the wind, beyond the sound, and beyond the limit, the speed has also reached a terrifying level!

The furious true qi containing anger was injected into the blade, and a dense knife curtain suddenly bloomed in midair, and the flames were in the air, and the light in the illuminated passage was dazzling.

"Kill!"

When this knife curtain reached a certain level, Lu You exhaled violently, as if this killing word wanted to vent all the anger in his heart, to slash the enemy under the knife, and burst out the potential of his whole body heartily!

The terrifying flame knife with the power of thunder, fell from the sky, and the fierce and incomparable knife slashed at the rolling ice mist, only to hear a loud bang, the ice fog completely disappeared, not only that, but the terrifying flame sword, but also swept away to the fierce spirit not far away in the form of a flood that broke the embankment!

"Roar!!

Sensing the danger of Lu You's knife, a piercing roar suddenly came out of the fierce fang's big mouth, and the wings on his back fluttered rapidly, driving his body to quickly dodge, and at the same time, his mouth opened again, spewing out a mouthful of ice mist that was even thicker.

The flame blade collided with the ice mist, and a terrifying roar of energy erupted, and the entire passage suddenly had two heavens, sometimes hot as magma, sometimes as cold as ten thousand years of ice.

Long Xue, who was already in full recovery, was awakened by the stimulation of this ice and fire, and when she opened her eyes, she saw a spectacular scene outside, her mouth slightly turned into an O-shape, she never knew that Lu You's strength had grown to such a terrifying level.

No one knows better than her the terrifying strength of the fierce spirit in front of her, but she didn't expect that Lu You could fight with this beast on a par with it, it was incredible!

"Haha, happy, it's been a long time since I've had this pleasure!

At this moment, Lu You let out a long laugh in the passage, and the whole person changed from the low-key accumulation of the past, exuding an incomparable domineering aura all over his body, and his eyes were shining, like a god of war who came out of the battlefield of Shura, killing gods when encountering gods, meeting Buddhas*, destroying everything!
