While Qing Yanlou and the Blood Knife Gate and others were fighting against the third-line Black Flame Snake, Yi Chen, who was in the team of the Invisible Sect, was also experiencing a sudden battle.

"Boom ....."

The gray mist outside the entrance of the cave was cleared by the impact of the more turbulent gray fog inside the cave, causing a clear space to appear on the three-meter path at the entrance for a moment.

It also cleared the ground of a finger-deep gray dust, revealing several black skeletons that had been swept up by the impact of the impact and then fell from the edge of the three-meter trail deep underground.

It's just that the underground space is still shrouded in a thick and heavy gray haze, and the gray haze in the second half of the night is even denser, this small Qingming space has not been able to stop the erosion of the gray haze, and it only takes a few breaths to be filled again by the gray haze gathered around, and the space has returned to its previous state again.

However, the air that stirred out of the cave did not stop there, but was accompanied by the aftermath of the true qi impact one after another, once again blocking the gray mist at the entrance of the cave, so that the gray mist could only linger outside the cave without an inch.

The aftermath of the terrifying energy that shook from inside the cave hit the loose rock walls of the cave, and the dry soil that fell from the rock walls flew up one after another under the impact of the aftermath, drowning the gray dust of the ground underneath, forming a layer of faint dust.

There is not much light in the cave now, and the fluorite shining on the top of the cave has completely fallen off from it due to the shock of the aftermath, and it is sparsely buried in the soil on the ground with a faint light.

Then he was involved in the aftermath of the sudden impact of the battle, under the destruction of the terrifying energy contained in the aftermath, the already fragile fluorite surface was covered with countless tiny cracks in the blink of an eye, and then was completely smashed under the impact of another wave of aftermath, leaving only some small fluorite particles in the difficult release of their own brilliance, wanting to illuminate the dark cave without a trace of light.

It's just that this little bit of light didn't last long, because there were not a few battles in the cave, wave after wave of battle fluctuations came, and each wave of impact could easily crush the small fluorite into powder, and the light that could shine on the cave disappeared at all.

No, it's not true, the only thing left in the cave at this time is dozens of humanoid light clusters scattered in the cave, this is the light that each cultivator stimulates to protect their own body, and while protecting them from being eroded by some kind of power that is filled with space, it can also scatter the light of everyone in their body in the cave, so that they can also see the scene in the dim cave.

The dim light did not fully reveal the scene in the cave, and it did not allow them to have an unobstructed view, but for those of them who were cultivators in the Innate Realm, as long as they were not completely shrouded in darkness, they could clearly see everything around them with their eyes.

Standing at the edge of the cave, he glanced at the others who were also close to the edge of the cave, Yi Chen's gaze was slightly condensed, and his tense body was completely in the most defensive state.

A pair of tiny eyes flickered slightly, unhindered in the dim cavern, taking in everyone's battles.

Except for the men and horses belonging to the Invisible Gate, who cooperated with each other and stood at the exit to the outside of the cave to guard the only passage, everyone in the cave was now fighting their own battles, and they would not easily intervene in the other people's battles until they had solved the enemies they faced.

The emotions of cultivators can be described as clear between public and private, and the vast majority of them are their selfishness, and the battle they are facing at the moment is still relatively difficult, and it does not affect their true purpose.

Before seeing the real opportunity, the only thing that needs to be paid attention to and protected is yourself, as for the others, they are either competitors of the last chance, or a dry bone on the way to fight for the last opportunity, which is a fact that is difficult to change no matter what kind of danger you face.

"Woohoo..."

While observing the other people's battles, Yi Chen did not relax his vigilance, several sounds from the rock wall appeared in his ears, although he did not perceive the breath from them, he could roughly judge from the sharpness of the sound of breaking the air, and his heart suddenly shook slightly.

He quickly made the best judgment in his heart, and his agile body took a step behind him, and the momentum revealed on his body rose instantly, and he did not exceed the realm of turbidity pill by half a step, and only stopped when he broke through the critical point of the realm of turbidity pill.

Although he was facing the danger from the creatures on the rock wall now, Yi Chen did not make an act of completely exposing his cultivation, because he knew very well that if his true cultivation was exposed in advance, it would inevitably arouse the suspicion and jealousy of others at that time, which would be very unfavorable to his next plan.

What's more, in the previous battle, he could already roughly judge the strength of these creatures by the size of the sound of breaking the air, and the strongest thing that was attacking him at the moment was only the half-step Turbidity Pill Realm, with his cultivation in the county now, combined with his combat experience in the Turbidity Pill Realm, he could easily deal with it, and there was no need to completely expose his true strength at all.

At this time, the cyan long sword he held in his hand shone brightly, and his mind was extremely focused on the sword, and at the same time, he also poured his understanding of the sword into it, and then a sharp feeling appeared on the slender sword, and the faint white light formed a layer of restrained sword shape wrapped around the sword body.

Seeing the appearance of this layer of light film, Yi Chen nodded secretly in his heart, and then brandished his long sword and stabbed at the three slender black shadows that appeared in front of him.

The speed of the three slender black shadows was extremely fast, but this was not the case in Yi Chen's eyes, he could clearly see the scales of the three slender black shadows flickering black, and he could also see the two sharp fangs in the open snake's mouth, and even more from the flame pattern on their foreheads, the red flames that suddenly erupted from the flame pattern on their foreheads brought him a slight sense of crisis.

That's right, the one who appeared here was also a third-line black flame snake, and judging from the number of things under him and the ashes left on the ground, the number was much more than that of Xiao Qian's side, and it was also a few points stronger in terms of strength.

"It's now"

Just as he was about to confront the three third-line black flame snakes, Yi Chen's body suddenly fell backwards, and a trace of triumph flashed on his face facing the top of the cave, and then the cyan long sword wrapped in a white light film turned in his hand, and the three third-line black flame snakes that grazed his face were stopped and slashed.

The cyan long sword in his hand once again took advantage of the momentum to slap several times in the air, completely erasing the last wisps of vitality of the three third-line black flame snakes, and at the same time, it also slapped the blood and mutilated snake bodies that spewed them onto the rock wall of the cave.

At the same time, the cyan long sword slid slightly to the ground under his back, and his leaning back body stood up straight again with this skillful force, and after glancing at the distance between himself and the center of the cave, his body moved again, and once again met a sudden attack of the three-line black flame snake.

The three third-line black flame snakes he had slain behind him were wrapped in crimson flames and burned, and finally turned into a pile of black ashes.

Yi Chen didn't get information about the third-line Black Flame Snake from the Invisible Gate, not only because their attack was very abrupt, but also because Liu Hong's strength was well known, and no one wanted to touch his moldy head at this time.

However, during this period of battle, although Yi Chen didn't know the name of the third-line black flame snake, he could already know from the battle that it was not only extremely fast when it took off, but also understood that the black scales on its body had extremely amazing defensive power.

Not only him, but also the cultivators who were still fighting, each of them while dealing with the third-line black flame snake fighting with them, was also keeping a distance from the center of the cave at all times, as if there was a danger in the center of the cave that they were all afraid of.

In the rush of running, Yi Chen once again dodged the surprise attack of a three-line black flame snake, and the cyan long sword in his hand slashed the other one at the same time, and he was about to turn around and swing his sword to meet the next blow.

At this moment, a fierce aftermath of the battle suddenly came from the center of the cave, and the turbulent energy impact echoed in the cave with a radius of nearly thirty meters, and it did not dissipate for a long time.

Under the impact of the aftermath of the battle, the cultivators who were fighting at the edge of the cave had a surge of light, and they cautiously and solemnly separated most of their minds to resist the huge impact contained in the aftermath, carefully stabilizing their figures.

As for the third-line black flame snake that was fighting them, it was thrown onto the rock wall under the impact of the aftermath pressure, and the weaker ones were even stiffened the moment they came into contact with the aftermath, and they turned into a crimson flame and fell from the sky without any life.

"Boom Boom...."

"Click... Click...."

The loose dirt on the top of the cave continued to fall under the impact of the shocking aftermath of the battle, and dry dust rose up throughout the cavern, making it impossible to see the real battle situation in the middle of the cavern.

At the same time, there were several cracks that were one fist wide, starting from the middle of the cave to shatter and spreading in all directions, spreading to the edge of the cave without stopping, still shattering towards the top of the cave with an unstoppable momentum, looking like a huge cobweb spread out, and they were struggling to escape from this place as if they had fallen on the cobweb.

"It is worthy of being a Jade Pill Realm powerhouse who is only one foot away from the Spirit Realm, even if he has deliberately suppressed his strength, he can still cause such damage here."

Killing a three-line black flame snake again, Yi Chen shook off the slightest trace of blood stained on the sword, took a step back to avoid the crack on the ground, and glanced at the middle of the dusty cave without a trace, his heart was full of sighs.

This time the battle came very suddenly, not to mention Yi Chen, even the Invisible Gate and the others, who knew the danger here, did not expect the surprise attack of the third-line Black Flame Snake to be so sudden.

After all, the Invisible Gate and Qingyan Tower have been operating this place for three years, and they have deliberately set up such a place here, so they are very aware of the habits of unknown creatures living in the gray mist, and they must also know when they will appear and in what way they will attack.

However, this attack was obviously no longer Liu Hong's expectation, because when the third-line black flame snake first appeared, the invisible door guards guarding the exit of the cave were the first to die, and judging from their reactions and expressions, they obviously did not expect this.

In addition, after Liu Hong's incident, Yi Chen had seen doubts on his face several times that should not exist, which made him understand that this battle might come, but it would never happen in this way.

What's more, this group of three-line black flame snakes that suddenly arrived were like ghosts without any breath, and they cleverly hid their slender snake bodies in the gray mist, so that no one could sense the breath on their bodies, which was also a mystery.

It was precisely because they couldn't feel their breath that they took the lives of no less than ten people when they first appeared, and then relied on numerical suppression, with the first attack, killing a few people again and causing many people to suffer some injuries, and then people and snakes fell into a fierce battle.

After a long battle, Yi Chen also discovered the third fact that made him feel frightened, these third-line black flame snakes that appeared here did not just have amazing speed and physical defense, but a kind of chronic poison carried by their teeth.

Others may not notice it at first, but Yi Chen has the attainments of a first-order alchemist, and when these third-line black flame snakes appeared, he discovered this from his instinctive cognition.

And in the ensuing battles, he finally confirmed that his guess was correct.

Because nearly half an hour has passed since the appearance of this group of third-line black flame snakes, in this half an hour, except for many cultivators who have been bitten by them have stiff limbs and reacted more and more slowly, and thus have been killed by the third-line black flame snakes, nothing has happened to other cultivators who have never been bitten by third-line black flame snakes.

Moreover, among the cultivators who had been bitten, except for some cultivators who had taken the Detoxification Pill at all times and could temporarily suppress them, the rest of the cultivators had already been killed by the poison of the third-line black flame snake.

And this can also be seen from the performance of the invisible door group, two of them were injured by the third-line black flame snake, but with a little fear after taking the antidote pill before they dared to join the battle again.

At the beginning, no one in the casual cultivation realized this, and because of this, they experienced the most difficult battle under unknown circumstances, and the team that had originally numbered more than sixty people was reduced to less than forty people, and the losses were terrible.

However, they should feel even more fortunate, because there is Liu Hong of the invisible door in this group, if it weren't for his action to drag the two third-line black flame snakes that pose the greatest threat, their battle would be even more difficult, and the losses would be even more heavy, and in the end, maybe the whole army would be wiped out because of this.
