Inside the cave passage, perhaps because of the successful performance of the shadow body technique under the stimulation of the third-line black flame snake, Yi Chen's current body flexibility has improved a lot, and it is very easy to dodge some of the gravel and dirt that fell above his head one by one, and even in the face of the sneak attack of the third-line black flame snake encountered along the way again, he can now easily deal with it with his body speed, and can quickly solve the battle.

This is the strength of the Sandan Mortal Technique, the difficulty of getting started is much more difficult than the ordinary Mortal Technique of the same level, not to mention, it also takes the whole mind and body cultivation of the Sandan Realm cultivator to learn.

And once the body can be successfully stimulated, the accumulation of long-term practice and cultivation will inevitably explode in the blink of an eye, allowing the practitioner to quickly adapt to this increase in speed.

It's just that the current situation in the passage is very critical and complicated, and the passage of less than twenty meters has been filled with soil up to one meter deep, and the height of the accumulation is still increasing at a rate visible to the naked eye.

In particular, the soil that had fallen down was very dry and soft, and it was difficult for ordinary cultivators to borrow much strength from it, let alone deal with the collapsed rubble and beware of the third-line black flame snake hiding in the darkness.

Therefore, in this short distance, the two Yi Chen, who are in the passage, need to be vigilant and cautious at all times, and slow down to deal with all kinds of dangers that may arise, so in their feelings, the path they are walking in front of them seems to be difficult to see the exit of the passage.

"Boom...."

In this seemingly long but very short time, Yi Chen, who was walking cautiously in the passage, finally approached the exit, and the sound of slapping not far away from him clearly in his ears did not make him relax his due vigilance, and the expression hidden under the cloak became extremely serious, and the body that was moving forward stopped directly here.

Looking at the exit of the passage that could only accommodate one person, Yi Chen's expression became more and more solemn, and the long sword that he had been holding in his hand couldn't help but clench a little.

"Brother Tai, the situation here is getting more and more dangerous now, there is the exit of the passage ahead, if it drags on here, it will be unfavorable to the two of us, I think it is better for us to leave as soon as possible."

The pace of the casual cultivator who followed Yi Chen also slowed down at the same time, and after glancing at the position where Yi Chen was standing, he quickly checked the exit that had been blocked by the accumulation of more than a meter of soil, and his face was full of doubt, as if he was very puzzled why Yi Chen stopped.

For the scattered cultivation that was gradually approaching behind him, Yi Chen only glanced back with a little vigilance, and his body didn't have too many defensive movements, and he didn't pay too much attention to it.

The body hidden under the cloak leaned forward slightly, like a fierce tiger hunting, and every muscle on its body reacted instinctively under the dangerous aura that lingered around it, and every place trembled slightly.

The roar from outside the passage was getting louder and louder, and the dense cracks had expanded into cracks, all over the rock wall at the exit of the passage, and each roar was accompanied by a more and more serious collapse, and the situation was now very critical.

His eyebrows furrowed slightly, and the long sword in his hand quickly stabbed deep into the earth, and then he lifted it up in a very short time, only to see a pitch-black serpentine skeleton appear in front of him with the long sword.

Seeing the skeleton of the three-line black flame snake, Yi Chen's heart moved, and he carefully sensed the dirt ground around him, the light in his eyes flashed several times again, and the long sword in his hand fell again towards several positions.

There was almost no hesitation in the fall and provocation of each sword, and each time there would be a black snake bone as black as carbon hanging on the tip of the sword, and what was even more surprising was that these snake bones buried under the soil were still exuding a faint heat breath, as if they had just died and had been buried in the dirt shortly after death.

Sweeping the pitch-black snake bones that fell in the air one by one, the sword in Yi Chen's hand moved quickly, and the pitch-black snake bones were completely shattered under his sharp sword, turning into black powder in the sky, floating in the air and mixing with the fallen soil, and then said in a slight tone: "The strength of these snakes Brother Tai has seen with his own eyes, and the people who went out before us are indeed not ordinary cultivators, but I don't believe that they will be so easy to deal with, so I hope Brother Tai will be more careful in the future."

"Thank you brother for the reminder."

Yi Chen's kind reminder made the scattered cultivator behind him slightly stunned, but he quickly recovered, his steps moved slowly, looking at the direction of the cave with a serious expression, and at the same time, the breath on his body began to slowly move and release.

Yi Chen didn't specifically point out the current situation, just a kind reminder to this casual cultivator, after all, he and this person are only in Pingshui, it is difficult to see a person's sincerity in a short period of time, and it is the limit to remind him now, which can be regarded as a reminder before repaying him.

This casual cultivator was not too surprised by Yi Chen's reaction, as a casual cultivator, he naturally knew that in this situation, in addition to believing in himself, everyone else needed to be careful.

However, he still nodded his head at Yi Chen's kind reminder, because just a few pitch-black snake bones that Yi Chen picked out from the dirt actually explained the problem.

You must know that the number of cultivators who left before the two of them entered the passage was not a few, among them, there were quite a few cultivators in the realm of turbidity pills alone, and there were no longer a few cultivators in the realm of half-step turbidity pills.

It is already inconceivable that there is no trace of them at the moment, and there is no way to tell the truth of the matter by only finding some traces of battle left by them during the battle along the way, and now there are no cultivators to see them, which undoubtedly shows that the people before them have left the passage safely.

For these scattered cultivators, Yi Chen is not very worried, their strength is not weak, as long as they leave the cave, they can fully exert their strength with peace of mind, even if they are fighting under the condition of the invisible gate and others, they only need to spend a little time to deal with the third-line black flame snake that followed them out, and quickly end the battle.

Once they are resolved, they will be able to carry out their own plans with their own hands, but Yi Chen believes that when the time comes, whether they agree or not, under the deterrence of Liu Hong's strength and cultivation, assisting the Invisible Door and the others in the final finishing work will only be their inevitable result.

These Yi Chen had already taken Liu Hong's purpose into account when he discovered it, and he had compared his true strength in his heart, and after coming up with an approximate time and time difference, he would choose to suddenly break out of the battle.

It's just that at the moment, it doesn't seem to be as they think, these scattered cultivators don't seem to be caught in the battle due to the entanglement of the third-line black flame snake, but they start to assist the invisible door and others to block the entrance of the passage a lot of time in advance.

This can be clearly judged from the orderly fluctuations coming from outside the entrance of the passage, if the battle of strength is completely broken, no matter what the means, the fluctuations will only become chaotic, not so orderly.

Combined with the skeleton of the three-line black flame snake that appeared in front of him, this result and possibility are even more self-evident, it must be that Liu Hong personally forced the three-line black flame snake that followed him back into the passage, and only this explanation is the closest to the truth.

Thinking of this, Yi Chen checked the exit of the cave at an extremely fast speed, and after a few shocks in his heart, he finally found what he was looking for in a few cracks diagonally above his head.

"Sizzle..."

Just as Yi Chen looked, several pairs of blood-red eyes flashing with dangerous light appeared from the cracks, and at the same time, there was a faint voice that made Yi Chen feel familiar.

After that, I saw three long black snakes exuding the aura of the Turbidity Pill Realm swallowing the fishy black cores in their mouths, and a cold light flashed from the crack in their small eyes.

This is not the end, after these three three-line black flame snakes of the turbidity pill realm appeared diagonally above the two of them, several figures of three-line black flame snakes also appeared from the left and right sides of the two at the same time, all of them were clinging to the cracks and rock walls and moving, even if the rock walls were shaken, they could not be thrown off the rock walls.

"These damn beasts!!".

Seeing that the exit was right in front of him, but because of these hidden three-line black flame snakes, he had to stop for a while, and the scattered figure behind Yi Chen couldn't help but curse in a low voice when he cautiously came to Yi Chen's side.

Perhaps what made him even more angry was the actions of these third-line black flame snakes, if it weren't for Yi Chen's secret sense that he didn't choose to stop, the two of them were only afraid that they would be attacked in the joy of approaching the exit, and the consequences would be unimaginable.

"This brother, if I want to leave safely from here, I can only join forces to take an adventure, I don't know what Brother Tai wants", after approaching Yi Chen, this loose cultivator's face has changed many times, and in the end, he can only forcibly take action to get rid of the anger of these three-line black flame snakes who have surrounded him, and speak to Yi Chen with great sincerity.

Yi Chen didn't think about it for long, in fact, he already had this idea when he found these third-line black flame snakes that were not giving up, so he nodded after the scattered cultivation proposal.

Seeing that Yi Chen agreed to deal with these three-line black flame snakes with him, Sanxiu's face was happy, and his originally tense body was loosened, and his body flickered to take the lead in meeting the three third-line black flame snakes that catapulted from the side.

Seeing this, Yi Chen also nodded slightly in his heart, his figure moved closely behind, the long sword in his hand lightly pulled in the air in front of him a few times, and the sword light with a sharp edge in the Dao appeared one by one, and flew out towards his left front at a lightning speed, accurately hitting the incomparably hard black scales of the third-line black flame snake, and there was a dense jingle symphony.

Except for the three third-line black flame snakes with the strength of the Turbidity Pill Realm who were still peeking on the sidelines, looking for an opportunity to sneak attack, the third-line black flame snakes at the exit of the passage had all participated in the attack and killing battle against the two.

Without their existence, with the strength of Yi Chen and the others, even if the entrance of the passage at this time was close to the critical point of collapse and would collapse in the aura fluctuations caused by their outburst, they would definitely be able to rush out of the passage in the blink of an eye and leave this place safely.

However, it is precisely the strength of the two of them that once they explode, it will become the last help to overwhelm the passage, and under the watchful eye of the third-line black flame snakes of the three turbidity pill realms, it is difficult for them to guarantee that they can get out of the battle in a short time, if they fail to leave in time, they will likely be left behind at the same time, and they will fall into a real battle to the death.

This time facing the siege of several third-line black flame snakes again, the performance of the two seemed to be a little stretched on the surface, but the action was not as difficult as before, every dodge, move, and defense were very flexible, and the only thing worthy of their vigilance was the three third-line black flame snakes that were still peeping, and the actions of the two did not receive much impact.

The two people in the battle quickly noticed the reason for this obvious contrast, which was all because the third-line black flame snakes fighting with them were not in their heyday, the aura on their bodies was very disordered, and the real combat strength was similar to the previous two snakes, and the threat to them had been greatly reduced.

And during the battle, the third-line black flame snake that was not injured by the two would spill a few traces of blood from time to time, and the burning flames brought a faint light to the passage where the earth had fallen, so that the two of them noticed the scars on the body of the third-line black flame snake at the same time.

The number of these scars was not very large, but the scales around each scar had completely peeled off, and it was clear that the flesh exposed to the air had been covered in a layer of black-gray substance.

Seeing this layer of gray-black substance, Yi Chen was slightly stunned, and then instantly woke up, the reason why these third-line black flame snakes did not incinerate themselves because of the effect of fiery fire poison was probably the reason for this layer of black-gray substance.

While they were fighting, the two of them had not forgotten that their main purpose was to get out of the passage, so they were both deliberately bringing the battle to the entrance of the passage, which was getting closer and closer.

"Quick, there is a fight ahead, let's step up".

"This battle fluctuation seems to be deliberately suppressed, it seems that the situation has become more and more complicated, if we don't want to die, we should hurry up and keep up."

The two men in the middle of the battle soon heard a jumble of voices from the darkness behind them, and a faint glow could be seen as they glanced into the back half of the passage, getting closer and closer to their location in the dusty passage.

The two of them glanced at each other as if they had a heart, and then the speed exploded again, ignoring the three-line black flame snake that was entangled with them, and rushed directly towards the outside of the passage where only one person was left to pass.

"Sizzle....."

At the same time, the three third-line black flame snakes who had been watching seemed to be aware of the intentions of the two of them, and the speed of swallowing the core suddenly accelerated, and the snake body that had already been coiled into a circle catapulted in an instant, one of them fell from the top of the two people's heads at an extremely fast speed, and the other two fell on both sides of the cave entrance to block the exit of the passage, and the two pairs of scarlet bloodthirsty eyes stared at the two of them motionlessly.
