After Nangong Nu fell down, he cried out in pain. The wound on his forehead, which had just healed, was broken again, and blood gushed out all over his face.
Nangong Wei saw the opportunity early and raised a light curtain with his hands to block the chaotic energy wave. From his surprised expression, it can be seen that he was also struggling.
He was just standing nearby, and was hit by the aftermath of the fight between the two men, and he almost failed to block it.
Master Flash sneered: "Didn't you say that no one can listen to your piano playing? The song you just played was just that good."
The old man Tianqin said disapprovingly: "Shanying, after so many years, how come you haven't improved at all? I was just testing the strings just now, I haven't played a song yet. You want to hear a song, well, I'll give you one, Phoenix Dances in the Sky."
Old man Tianqin let go of the phoenix-head harp in his hand. The phoenix head of the harp seemed to come alive, emitting colorful lights. The body of the harp floated in the air, lying horizontally in front of old man Tianqin.
Nangong Wei and Nangong Nugang looked at it in amazement, knowing that the Phoenix-Shou Qin was a powerful immortal weapon with immense power.
Master Shanying and his junior fellow Demon Lord Feiying looked at each other with anger in their eyes.
They encountered this situation when they attacked the Demon Fairy World three thousand years ago.
At that time, they met old man Tianqin, who also made the same move, firing wildly and violently with powerful sonic waves, which hit them so hard that they were injured and had to flee before they could use half of their shadowless magic skills.
They have not forgotten the three thousand years of humiliation, and sometimes they even seem to hear the frantic sound of the piano in their dreams, which makes them feel frightened.
Master Flash said in disgust: "Sure enough, it's still the same trick, it hasn't changed at all, but my Shadowless Magic Skill is not what it was before."
Master Flash suddenly disappeared from where he had just stood, and old man Tianqin quickly pressed the ten fingers of his hands in the air, like an elegant conductor, waving his fingers in the air and beating a graceful rhythm.
But old man Tianqin is not just keeping the beat, he is unleashing a powerful killing force.
The strings of the phoenix-shou zither kept vibrating, but surprisingly, there was no sound.
Nangong Nu asked Nangong Wei in surprise: "Sir, the strings are constantly vibrating, why is there no sound at all? Is it because my ears are not working well?"
Nangong Wei had a relaxed and contemptuous look on his face: "I can't hear any sound either. This old man's piano may be broken. He can't make any sound when facing our Master Flashing."
Demon Lord Feiying glanced at Nangong Wei coldly: "Ignorance, this is the highest realm of sound wave power, the soundless sound. Don't think there is no sound, that's because all the sound wave energy is concentrated to attack my brother. The sound waves are not scattered or chaotic, so of course you can't hear it, it's not that the piano is broken. Your knowledge of magic and martial arts is so poor, no wonder you can't beat the human race."
Nangong Wei and Nangong Nu's faces suddenly turned red and white, and they felt their faces burning.
Nangong Wei said to Feiying Demon Lord with a wry smile: "Senior is right, we are too ignorant."
Demon Lord Feiying didn't bother to pay any attention to them and was concentrating on watching the battle between his senior brother Master Shanying and Old Man Tianqin.
Boom, boom, boom. Although the strings were vibrating without any sound, Nangong Nu and the others felt the powerful energy waves, like whistling meteors, constantly flying over their heads.
Master Flash couldn't see anyone at all. He kept changing his shape and moving quickly to avoid Old Man Tianqin's silent power.
The buildings around the military factory were in a terrible state.
The walls of the factories kept bursting and collapsing. Before long, several solid factories built with huge stones were all razed to the ground.
That was a military factory built with huge stones to strengthen its defenses. It was very solid and could withstand the attacks of magic crystal cannons. Unexpectedly, it was razed to the ground in the face of the silent voice of old man Tianqin.
Among those present, only Demon Lord Feiying could see his senior brother's figure. That was the highest level of shape-shifting, which was invisible to ordinary people's eyes.
When one reaches the eighth level of Demonic Element, his figure flashes and cannot be observed with the naked eye.
It was like when old man Tianqin reached the realm of celestial immortals, his phoenix-head harp could no longer produce any sound, and he was completely using a powerful energy attack.
Nangong Nu and Nangong Wei could neither see nor hear the fight between the two of them.
In their eyes, there was a strange harp floating in front of the old man Tianqin. His fingers were plucking the strings in the air. The strings were vibrating by themselves, but there was no sound. Even the sound of the wind could not be heard.
Old man Tianqin had a solemn expression on his face, as if he was facing a formidable enemy. However, there was no enemy in front of him, only little phantoms of black light constantly passing by.
However, the surrounding buildings were blown up and razed to the ground by the energy waves generated by the fight between the two of them.
Nangong Wei and his companions were horrified by the battle, wondering if they would be blown to pieces like the factories.
Old man Tianqin had no time to care about their lives or deaths. He was concentrating on dealing with Master Flash.
A little bit of sweat oozed from old man Tianqin's forehead, but the back of his clothes was already wet.
Boom! A deafening explosion sounded in the air, and Master Flash fell from the air with an angry look on his face. His white hair stood up on his head like steel.
He clenched his fists and wanted to say something, but he just opened his mouth and no sound came out.
He had just used up a lot of his physical strength and magic power by performing the Shadowless Magic Skill. Even though he had changed his shape to the limit, he still had not been able to break through the defense of the old man Tianqin's Silent Sound. He was also captured by the Silent Sound and suffered a heavy blow from it.
This soundless voice almost made him speechless. He secretly adjusted his magic energy and stuffed a small black pill to replenish magic energy into his mouth.
It can be seen that Senior Brother has consumed a lot of magic energy, Feiying Demon Lord asked a little worriedly: "Senior Brother, how is it?"
Master Flash took a deep breath to regain his composure before speaking.
Master Flashing Shadow had a look of disdain and anger on his face: "I haven't seen this old guy for so many years. His skills have improved a lot. It seems that he has reached the Heavenly Immortal Realm. I didn't expect that he could take on my eighth-level magic power of the Shadowless Magic."
Old man Tianqin also stuffed a pill into his mouth to replenish the consumed immortal spirit, his face solemn.
In fact, in the battle with Master Flash just now, Old Man Tianqin was slightly better. He broke Master Flash's shadowless magic and revealed his whereabouts.
But old man Tianqin did not feel any joy of victory, because, although he broke Master Shanying's shadowless magic for a while, he also consumed a lot of his immortal spirit.
The key point is that there is another Demon Lord Feiying standing next to him who hates him even more and is eyeing him covetously.
His strength is no less than that of Flash Master.
