The sword qi that Qin Yun urged was called the Right Shaoyin Invisible Sword Qi, and the Left Shaoyang Invisible Sword Qi belonged to the matching sword technique, and after the two sets of sword techniques were cultivated to the realm of pure fire, they could be combined into one, and they could unleash a powerful body-breaking formless sword qi.

Whether it is Zuo Shaoyang or Right Shaoyin, or the Body-Breaking Invisible Sword Technique, they all belong to auxiliary sword techniques, and the ultimate purpose of cultivating them is to integrate the invisible sword qi into the sword weapon, and then be able to unleash the thunder sound sword qi!

This set of step-by-step Xuanmen authentic sword technique cultivation methods is the secret of Qinglan Sword God Luo Yi, but his only relative, Mingxiu, has no intention of cultivating the way of the sword, so it has been passed on to Qin Yun.

This time, Qin Yun went deep into the Fire Dragon Cave, one of the important purposes was to use the special environment of the Fire Dragon Cave to cultivate these two sets of invisible sword techniques, so when facing the maze fire bat that flew in, he did not pull out the Tianwen Sword, but launched the sword qi empty-handed to meet the enemy.

Chirping!

What Qin Yun didn't expect was that as soon as his invisible sword qi shot out of his fingers, the maze fire bat over there immediately reacted, screaming and flapping his wings to dodge!

The formless sword qi swept past the fire bat's flipped body, only scratching a shallow scar on the scales covered by its skin, and it was not able to cause any damage to the fire bat.

The maze fire bat's ability to react quickly to the enemy's initiative was definitely beyond Qin Yun's expectations, but the right Shaoyin formless sword qi was the same as the left Shaoyang's formless sword qi, although the power was not very strong, but the speed of the sword change was extremely fast.

The originally curved middle finger of Qin Yun's right hand suddenly popped out, and the second sword qi roared out, hitting the wings of the maze fire bat with incomparable precision, and suddenly broke a big hole in the flesh wing!

Squeak!

The maze fire bat let out a painful scream, and it tumbled in the air and dived down dozens of feet, then soared upward. The frequency of the wings swinging the fan was several times higher than before, and seven or eight black sharp thorns were shot out in a volley from the tips of the skeleton supporting the flesh wings!

Whew!

However, Qin Yun's five fingers on his right hand flicked continuously, and one after another invisible sword qi burst through the air, not only crushing all the attacking sharp thorns in the air, but also shooting out the wings of the maze fire bat.

Several of the sword qi directly hit the body of the maze fire bat, breaking its scales and dripping with blood, and let out a terrible scream and fell to the ground!

Although the Labyrinth Fire Bat is a mid-level demon beast and is good at sonic and tearing attacks, its weaknesses are obvious. The huge wings that spread out can be easily broken and lose the ability to fly, and they can only be slaughtered when they fall to the ground.

Qin Yun had carefully read the sect's demon beast classics, and he was very clear about the weaknesses of the maze fire bat, and he would naturally get twice the result with half the effort, and he would easily fall from the attack.

But Qin Yun didn't have much joy in his heart. Because he knows that the danger has not passed, but has just arrived!

Squeak! Squeak!

It was only a moment later, and there was a terrifying hissing sound in front of him, and black shadows appeared in groups as if they were ghosts, flying towards Qin Yun at an astonishing speed.

A large swarm of maze fire bats is coming, and there are at least dozens of them!

Qin Yun had already prepared for this, and he didn't panic in the slightest. Immediately let go of his left hand and jumped off the top wall of the tunnel, stepping on the rock wall and falling back to the ground.

Hanging in the air with one arm like this, he was not sure how to deal with the swarms of maze fire bats.

Woohoo!

Qin Yun's feet had just stepped on the sand when the fire bat swarm launched a fierce attack. They opened their red mouths and spewed out beams of sonic arrows!

Although the power of these sonic qi arrows was not as powerful as Qin Yun's invisible sword qi, dozens of qi arrows were shot densely at the same time, and Qin Yun did not dare to resist even if he had Zhengang armor. Immediately unfold your body and sweep backwards.

Poof!

Bundles of air arrows hit the ground in vain, and the powerful qi stirred up countless grains of sand. The blow on the rock walls on both sides made a crackling sound like rain hitting plantains.

Snort!

The first wave of attacks missed, and all the fire bats shot flesh-wing sharp thorns towards Qin Yun as if they had been pre-negotiated!

The number of this attack was much more than that of the air arrows, and the coverage area was also larger, Qin Yun simply stood still when there was no way to avoid it, and used his finger sword to perform the basic sword technique of breaking arrows.

In an instant, a dense sword net was woven in front of Qin Yun's body, and as long as all the flying sharp thorns collided, they all turned into powder!

Qin Yun cast the Left Shaoyang and Right Shaoyin sword techniques with both hands at the same time, and the six invisible sword qi came out together, even if the incoming sharp spurs were doubled, they would definitely not be able to break through his interception.

However, after completing the two waves of attacks, the bats were already very close to Qin Yun, and they swooped down from different directions and launched a close siege against Qin Yun.

The two claws of the labyrinth fire bat are extremely sharp, and the tips of the claws contain highly poisonous, and the thick armor can be easily torn apart by falling down on the body, and an ordinary innate martial artist cannot resist the close claws of five or six fire bats.

Knowing the strength of the other party, of course Qin Yun would not let dozens of fire bats pounce on him, his hands were raised high, and he suddenly urged the innate true gang of the dantian qi sea, raising the power of the invisible sword qi to the extreme.

The sword qi that shot out from the fingertips immediately turned crimson, although it was no longer "invisible", but the qi that contained the power of the Evil Fire True Gang was extremely powerful, and it pierced the bodies of the two fire bats in an instant!

In the face of the swarm of bats that kept fluttering, Qin Yun still stood still, but his arms waved left and right to release sword qi, shooting down one fire bat after another from the sky.

The sword form he used was extremely simple and direct, without any change in the back moves, it was purely with amazing speed and strong strength to complete the attack, no matter which direction the fire bat attacked him from, it could not escape the interception of the sword qi.

Qin Yun was able to do this, in addition to his own cultivation strength, more importantly, the help of Qiankun's spiritual supernatural ability, this small supernatural ability after upgrading and evolving, could allow him to have a keen insight into the dangers from his surroundings, and then take precautions in advance.

The screams of fire bats rang out one after another in the tunnel, fragments of scale armor mixed with flesh and blood splashed everywhere, huge corpses were stacked around Qin Yun, and the red blood soaked the sand, and then it was evaporated by the scorching heat, leaving traces of dryness!

The heavy casualties of their companions did not make the fire bats afraid, they seemed to be completely enraged by Qin Yun's killing, and they fell in the air one after another, and then they were shot down and fell to the ground, the scene was extremely tragic.

Qin Yun didn't care about the madness of the maze fire bats at all, on the contrary, he also felt sincere joy, because the latter's siege just allowed him to familiarize himself with and strengthen his control over the sword technique through battle, and his whole mind was completely immersed in the comprehension of the invisible sword technique of the left and right Shaoyang and Shaoyin!

It's a pity that this situation didn't last long, and in less than half a pillar of incense, all the fire bats were killed by him, leaving only a mess of corpses!

Grabbing it out with both hands, the six sword qi hit the last fire bat that was still resisting at the same time, twisting its entire body into pieces, and Qin Yun stopped attacking without finishing it.

At least hundreds of labyrinth fire bats died at his hands!

It's a pity! Qin Yun secretly regretted, because he had just comprehended a few more swordsmanship tricks, if there were dozens more fire bats, maybe he would be able to complete a small breakthrough.

If the fire bats who died tragically on the ground could know what Qin Yun was thinking at the moment, I am afraid that they would all vomit blood.

But fortunately, they were all dead, otherwise what would happen next would make them even more painful, Qin Yun used his sword qi to break open the corpse, and found the intact demon pill from it and put it in his pocket.

The Labyrinth Fire Bat is a mid-level demon beast, as long as it is an adult, it contains the demon pill, and its demon pill contains abundant fire spiritual power and medicinal power, which can be used to refine the best pills.

The purchase price of a Fire Bat Demon Pill in the Heavenly City Sword Sect was ten points of sect contribution, Qin Yun took over the corresponding task in the Heavenly Pole Palace before going down to the Fire Dragon Cave, and the number of these fire bats was enough for him to complete two or three missions.

In fact, the wings, skeletons, and claws of the fire bat can all be used, but Qin Yun's vision is different from before, and he can't look down on these materials of low value.

Of course, if the disciples of the sect who were struggling on the first and second floors of the Fire Dragon Cave knew that Qin Yun was so wasteful, I am afraid that they would really all burst into tears.

Squeak!

Just as Qin Yun was working tirelessly to collect the Fire Bat Demon Pill, suddenly a sharp howl came from the depths of the tunnel in front of him, which shook Qin Yun's eardrum and hurt faintly!

A feeling of danger suddenly surged into Qin Yun's heart, his face changed slightly, his right hand pressed the hilt of the Tianwen Sword hanging from his waist, gave up collecting the demon pill and prepared for battle.

The next moment, a huge black shadow appeared in Qin Yun's line of sight.

The appearance of the visitor is very similar to that of the maze fire bat, but the size has become several times larger, the wings are more than ten feet long, the body of the clam-headed rat is bulging, the fangs are exposed, and the claws are like eagles.

Its fleshy wings were dark red, and between the swings of the fan, flames scurried from the surface from time to time, and Qin Yun felt a strong scorching wind coming from a distance of dozens of steps, and it was not stable at all without expending a little effort.

The pupils of Qin Yun's eyes contracted suddenly!

Flamewing Fire Bat King!

A group of labyrinthine firebat groups has existed long enough, and after repeated battles among them, a powerful king, the Firewing Firebat King, will eventually be produced.

The Flame Wing Fire Bat King is a high-level demon beast, its strength is not comparable to that of ordinary fire bats, but it also has a high level of intelligence, cruelty and cunning are extremely difficult to deal with.

Qin Yun didn't know what kind of luck he had hit today, he had discovered the spirit jade deposit and was attacked by a group of fire bats, and now even the Flame Wing Fire Bat King had appeared!

He had no experience in fighting the Flame Wing Fire Bat King, but just listening to the scream just now, he already knew that the other party was definitely not something that could be easily won!
