Fang Shi has been studying the sound spell for a while, and he has a lot of precious materials on hand, not only the collection of Qingcheng Mountain, but also the secret transmission of the sound spell of each family obtained through the exchange of guò, and the secret art of the witch gate obtained from the Li family, especially the secret art of the Wu door of the Li family, which has transcended the boundaries of human beings and extended the sound spell to the world of insects.

To put it bluntly, the sound spell is the technique of superimposing mental power fluctuations on the sound waves, although the reason is simple, but the sound spell can be said to be the slowest type of spell in the entire Xuanmen, and even Fang Shi feels that the sound spell has been degrading, so it can be seen that the sound spell is more difficult to accurately master than ordinary spells or runes.

Fang Shi didn't dare to say that he was the most profound in the study of sound spells, but he thought that he did have a superior level in the study of sound spells on insects and animals, of course, this was also inseparable from his intuitive feeling of yin and yang breath, as well as his keen sense of mental fluctuations.

Fang Shi's goal at the beginning is the sound spell, the reason is that pure spiritual spells generally do not have a strong attack effect, this kind of soft kill is better for the target with higher intelligence, but against this kind of simple to only instinctive consciousness of the bug, it may not be too difficult to disperse and disturb them, but it is difficult to kill them directly with pure spiritual spells.

Fang Shi didn't want a spell to go down at that time and make the Gu worms panic, but when the effect of the spell disappeared, these guys would continue to do what they should do. Of course, Fang Shi could also choose to expel them from the target's body, but that would require the psychic spell to be controlled to a very subtle level. It is also necessary to use slow casting spells to hold the spell for a long time. This is too demanding for the caster.

And even if Fang Shi can do it himself, what is the use? The problem now is that Soul Eater Gu is blooming in all directions. If Fang Shi can't find a simple and easy way to quickly promote and be mastered by the majority of warlocks, the situation will not be able to be controlled at all.

Therefore, the sound spell technique with strong effect and easy to be popularized has become the first choice of ashlar.

Fang Shi tried to combine a spiritual fluctuation that was opposed to the Gu worm's inherent consciousness fluctuations, and sure enough, the Gu worms were alarmed by this sudden mental fluctuation, and the Gu worms who were frightened by Yan Zòng wanted to flee one after another, but there were too many Gu worms in the petri dish. There was no space to dodge at all, so the Gu insects became frantically agitated, and the liquid in the huge petri dish suddenly tumbled as if it was boiling.

Xu Liquan, who was on the other side of the glass, was thrilled, for fear that if he was not careful, these boiling liquids would break through the confinement of the bottle, and this large pile of terrifying guys would jump out of the bottle, you must know that the person inside is the most important person in Huaxia at present, and there must be no problem, otherwise I really don't know what will happen!

Xu Liquan had the urge to rush in and drag Fang Shi out, but he held back stubbornly, and the current situation was on the verge of Blue Star's restart. At this time, he really didn't have the courage to go in and stop Fang Shi's efforts.

Of course. It's just that he thinks it's dangerous, Fang Shi doesn't feel dangerous at all, on the contrary, he is now relaxed and has found what the Soul Eater Gu is afraid of, which means that the end of this crazy little bug is not far off.

That's right, pure mental fluctuations can only scare the Gu worms away, if the number is small, then it is not difficult to expel the Gu worms, but when the number of Gu worms is extremely large, it takes a lot of time and energy to completely eliminate them, if the number of infected people is too large, this method of expulsion is simply unrealistic.

However, pure spiritual techniques have always had the habit of combining with material energies such as yin and yang breath and sound waves, which is also the consistent idea of the technique.

Fang Shi took a step back with satisfaction, the black liquid in the petri dish slowly subsided, and Fang Shi found a relatively small petri dish again, this huge petri dish glass was too thick, and it was too difficult to transmit the sound waves.

Xu Liquan looked at Fang Shi's movements strangely, and seeing that Fang Shi had re-separated some samples of Soul Devouring Gu, Xu Liquan felt an expectation in his heart. Fang Shi placed the palm-sized petri dish on the table, fixed it on the stand with a clip, and then took a step back, about a meter away, Fang Shi opened his mouth at the petri dish, Xu Liquan felt inexplicable, but he immediately understood that Fang Shi's voice was blocked by thick glass.

Xu Liquan patted his communicator and confirmed that the communicator was not broken, but Fang Shi did not turn on the communicator. He hurriedly looked at the small petri dish, the black liquid in the bottle seemed to be shaking slightly, Xu Liquan rubbed his eyes vigorously, the whole person was already attached to the glass, but the distance of five or six meters allowed him to only vaguely see the situation in the petri dish.

Fang Shi had been standing, as if he was also observing the situation in the petri dish, and after a while, Fang Shi pulled the camera and light of the microscope from the side, and carefully adjusted the light and camera.

At this time, Xu Liquan finally discovered the changes in the petri dish, under the illumination of the light, he found that the liquid of the petri dish seemed to be precipitating, the color of the upper and lower parts had obvious differences, the upper part had become lighter, and as time passed, it seemed to be more and more transparent, and the lower part seemed darker.

It's difficult, could it be that Fang Shi has found a way to kill the Soul Devouring Gu?!

Xu Liquan immediately turned his gaze to the display screen of the microscope, Fang Shi was adjusting the lens, and as the lens moved slowly, Xu Liquan saw the corpse of the Gu worm slowly sinking in the liquid, that's right! It's a corpse!

Xu Liquan's cheeks suddenly turned red, and he didn't know if he was wearing a three-defense suit or because he was too excited, his heart seemed to be blocked by something, and he couldn't wait to shout to sweep away the blocks in his chest, this feeling of ecstasy seemed to have not appeared for many, many years.

Fang Shi was also very happy, in the three-defense suit, Fang Shi's mouth was already grinning, he couldn't imagine that the effect of the sound spell was surprisingly good, especially against the Gu worms in the liquid, Fang Shi remembered the reason that the sound wave seemed to spread faster in the liquid, maybe there was this factor in it.

Fang Shi carefully observed the Gu worm in the bottle, and after seeing that he didn't see the active Gu worm, he simply infiltrated his spiritual power into it, in order to check accurately, this time he did not limit the intensity of the use of Yin and Yang Breath, and was pleasantly surprised to find that the Gu worm had been completely killed, but it was only a fifteen-second sound spell, and the effect was surprisingly good.

However, after Fang Shi's spiritual power penetrated in, some insect eggs were stimulated and hatched again, Fang Shi did not hesitate to come to the sound spell again, and then used the exploration technique to detect, this time it was completely killed, Fang Shi exhaled heavily.

There was a banging sound on the glass behind him, Fang Shi turned his head and saw Xu Liquan lying on the glass, looking at him with a flushed face.

Fang Shi grinned, turned on the communicator, and a slight electric sound came from the earphones: "Master Fang, yes, is there any progress?" ”

"Do you have a fever? You won't get infected, will you? ”

"No, no! I'm just a little excited, I just saw that those Gu worms are dead, I'm not mistaken, right? ”

"Hehe... Yes, they are all dead, they died from sound spells, I didn't expect these Gu worms to be so sensitive to sound spells, in fact, I should have thought of it a long time ago, Gu worms have always been sensitive to sound spells. ”

"Yes, can you be sure?"

Fang Shi pondered for a moment and said, "Then I'll try again." ”

Xu Liquan nodded vigorously.

Fang Shi quickly separated a part of the Gu worms again, this time the number was larger, and the thickness of the bottle was thicker, Fang Shi shared three rounds of one plus one sound spell to completely kill the Soul Eater Gu that had been repeatedly hatched in this bottle.

"Minister Xu, it can be determined that the sound spell technique is indeed effective."

"Great! That's great! I'll report the good news, by the way, Master Fang, is this sound spell easy to learn? ”

"It is easy for people who are used to sound spells to master, just now I seem to have seen the abbot of Fatong coming, he is a master of sound spells."

"I see, I'll call him over right away."

After saying that, Xu Liquan turned around and ran, but after running two steps, he turned back again, looked at Fang Shi through the glass and said, "Master Fang, what kind of warlock can use this sound spell technique." ”

"This... Probably... Fa Yan monk can be at this level. ”

Xu Liquan breathed a sigh of relief: "Great! Thank you, Master Fang! ”

After a while, the abbot of Fatong and Lou Jingzhong rushed over together, and the intercom system that had already passed the guò three defense suits from Lou Jingzhong shouted: "Fang Shi, really killed?" ”

"Is this a joke?"

Fang Shi opened the door of the isolation room and let Lou Jingzhong, Abbot Fatong, and Xu Liquan in.

"Be careful, this big bottle is full of Soul Eater Gu."

Xu Liquan subconsciously gave way to the side, and Lou Jingzhong smiled: "Don't scare me, since you can kill it, who is afraid." ”

"Hehe, if so many Gu worms enter your body together, I'm afraid it won't be too late to save you, why don't you sacrifice it?"

"Well, I still don't."

"Amitabha, Master Fang's merits are immeasurable."

Fang Shi smiled: "Okay, don't say anything politely, I'll teach you this sound spell right away, you can see if you can cast it, of course, it's good to make a comparison in the scene." ”

"Cut, look down on people, don't you?"

The abbot of Fatong habitually gave a salute, but it was strange to wear a three-defense suit to perform a namaten salute.

"Thank you Master Fang for passing it on, by the way, what is this sound spell called?"

Fang Shi was stunned for a moment, this one scratched his head a little: "It's called the Soul Destroying Spell." ”

Lou Jingzhong muttered: "What a broken name, isn't there a soul destroying technique?" And there are many kinds of soul slaying spells, so won't this soul slaying spell already exist? ”

Abbot Fatong smiled lightly: "It doesn't matter, then it's called the Soul Destroying Spell, and the other Soul Destroying Spells can be suspended from now on." ”

Lou Jingzhong asked strangely, "What do you mean?" (To be continued......)
