I don't know how wide the area shrouded in fog is, and if there are always bats and monsters coming out to disturb you, God knows how long it will take to get out?

After Duan Fei's careful observation, he could see that while this bat demon beast made a "rustling" sound, in addition to being used to disturb the enemy, it was also able to locate itself in the fog.

This is obviously the unique ultrasonic talent of bat-like demon beasts, which allows them to take the lead under the shroud of fog, and only when they take the initiative to attack, Duan Fei and Xiao Jin can launch a counterattack in a timely manner.

This passive situation made Duan Fei feel quite unhappy, and the strength of this bat demon beast itself was not strong at all, wouldn't it be a very unreasonable thing to let them continue to be so arrogant?

Don't look around, there is a fog that affects the line of sight, but if you really want to deal with the bat demon beast, Duan Fei naturally has a way!

You must know that in order to unite with Xiao Bai's spiritual power, Duan Fei increased the strength of his spiritual power to 1,500 points, which is definitely not a weak person among the cultivators of the Gathering Spirit Realm, and it is more than enough to crush these bat demon beasts.

Especially after Duan Fei slashed Demon Xuanyuan, he obtained the complete Heavenly Demon Eight-Tone Technique, just in terms of the sound wave technique, he can be regarded as one of the best among all the disciples of the Heavenly Demon Sect, and he was born as the ultrasonic nemesis of the bat demon beast.

After having an idea in his heart, Duan Fei naturally did not show the slightest mercy to his subordinates, only to see that after he opened his mouth and took a deep breath, an invisible sound immediately spread in all directions.

This sound is exactly the chaotic sound in the Eight Tones of the Heavenly Demon, even if the cultivator hears it, as long as the strength of the spiritual power is insufficient, it will instantly become disordered in qi and blood, and thus lose control of his body, not to mention this kind of bat demon beast whose strength is not very strong?

With Duan Fei's current cultivation realm, within a radius of a kilometer around his body, it was the attack range of the Heavenly Demon Eight Sounds, so after the chaotic sound of the Heavenly Demon Eight Sounds spread out to the surroundings, you could hear the sound of "puff puff" constantly coming from the fog, obviously the bat demon beast in the fog couldn't resist the impact of the chaotic sound, lost control of its body, and fell to the ground like this.

Although this kind of attack method cannot solve the life of the bat demon beast at once, it is equivalent to being swept away within a radius of a kilometer, and it will not be harassed by these bat demon beasts for the time being.

Duan Fei laughed and motioned for Xiao Jin to move forward quickly, and Xiao Jin's vertical leap was hundreds of meters away, and he only needed to jump twice, and he almost rushed out of the clearing area.

At this time, Duan Fei once again opened his mouth to speak, using the misty sound in the eight tones of the Heavenly Demons, so that I don't know how many bat demon beasts were confused, and they fell out of the fog in a dizzy state.

Facts have proved that whether it is a misty sound or a chaotic sound, it is not something that the bat demon beasts can resist, as long as Duan Fei continues to use the Heavenly Demon Eight Sounds again and again, these bat demon beasts in the mist will not have any threat.

In this way, Duan Fei should have taken advantage of such an opportunity to try to rehearse all the eight tones of the Heavenly Demons, and then naturally the sounds of shock, madness, stupidity, injury, breaking, and killing took turns to fight, and after all the eight tones came to a reincarnation, all of a sudden, the eight tones gathered together and turned into the final death sound!

Once the sound of death is issued, it will be the ultimate killing move of the Heavenly Demon Eight Sounds, as long as it is within the range of the sound wave, all the bat monsters will explode and die.

And the sound of death is like a ripple that can stir up sound waves in the air, so that the sound of death is constantly transmitted to a wider range, as long as it is a bat monster beast that has been injured by the Heavenly Demon Eight Sounds before, once it is affected by the ripples of the sound of death, it will also end up with an explosion and death.

Duan Fei is proving with facts that once the Heavenly Demon Eight Sounds turn into a dead sound, what a terrifying destructive power it will have, this is simply like an infinite flow of poison, capable of killing the enemy without a shadow and invisibly.

It is no wonder that the Heavenly Demon Eight Sounds are recognized by the Heavenly Demon Sect as the number one in sonic skills, and they are not allowed to be taught by the core disciples of the Heavenly Demon Sect, and they are definitely regarded as high-level magic skills second only to the inheritance exercises.

After practicing with the bat demon beast, Duan Fei can be regarded as having completely mastered this sonic technique, which is equivalent to having one more killer weapon when facing the enemy in the future, as long as he sees that the opponent's mental power is not strong with the eye of the god, then he can naturally defeat the enemy after using the Heavenly Demon Eight Sounds.

So Duan Fei opened the way with the Heavenly Demon Eight Tones like this, even if he was in the fog and didn't argue the direction, he could still go on a rampage.

If it continued like this, wouldn't it mean that the third layer of the Heavenly Demon Sect was nothing more than that? Or was it that Duan Fei and Xiao Jin were lucky, and the area covered by the fog was not a dangerous place now, so they could deal with it so easily?

However, Duan Fei did not relax his vigilance because of this, because under the shroud of mist, everything here is unknown, even if the bat demon beast does not pose a threat, but God knows if there are other dangers in the mist?

Then he went all the way forward, unconsciously traveling dozens of miles away, and he was still shrouded in fog for four miles, and he couldn't see where the end was.

However, I don't know how many bats and monsters have died under the eight sounds of the heavenly demons, Duan Fei can be said to reproduce the true nature of the demon killer, but it is a pity that these bat monsters did not bring even a little bit of righteousness to Duan Fei, and it is inevitable that there are some fly in the ointment.

According to the speculation of countless predecessors and sages, the third layer of the Nine Dead Towers is much larger than the entire Kyushu world, and there are too many places that have not been explored.

If you don't find anything here, can't you keep bullying a weak chicken like a bat monster?

If someone else is here, he will still worry about not being able to find a teleportation channel to leave the Nine Dead Towers, but Duan Fei has a space door to base up, so he is not worried about leaving the Nine Dead Towers at all, he will only feel a little bored to move forward like this in the fog.

Of course, as a cultivator, you have to be able to endure loneliness to some extent, after all, opportunities are not so easy to get, and you can't just have them if you want to.

As Duan Fei and Xiao Jin advanced forward for some distance in the mist, when Duan Fei used the Heavenly Demon Eight Sounds again, he suddenly noticed a trace of something unusual.

Now Duan Fei has a thorough grasp of the Heavenly Demon Eight Sounds, when he emits sound waves to spread outward, he can use sound waves to explore, once there is an obstacle in front of him, he can naturally know through feedback, which is equivalent to having the same effect as radar.
