Everyone frowned. The sound gave them a tearing pain, but they all had strong internal strength to back them up, so the pain was not that intense.

Xin'er, who had no effort, was the first to bear the brunt of the pain. He covered his head and beat his chest, which was already in excruciating pain.

"Xin'er, please bear with me."

Dugu Xing patted Xin'er's back with his palm, slowly injecting internal energy.

But even he himself was in some unbearable pain, and his internal strength was of no avail.

"What kind of sound is this? It has such magical power."

Because Liu Yun had the power of telepathy and his will itself, he was extraordinary from ordinary people, but he also felt the slightest hint of cramping pain.

"Brother Wang, hold your heart together, hurry up, let's go up and have a look."

Dugu Xing nodded, took back the palm on Xin'er's back, picked her up, and followed her quickly.

The higher up, the cramping pain became more and more obvious, and even Liu Yun couldn't help but cover his chest.

The ticking sound was already painful to their eardrums, driving them crazy.

"Yun'er..."

Suddenly there was a faint sound from inside. Liu Yun was shocked all over. He could no longer care about the pain and flew to the eighth floor to meet the ticking sound.

"Mo, dad, Feng protector!"

Liuyun exclaimed and ran away quickly.

One hand climbed up the iron fence, and the other hand held Dugu Mo's hand tightly.

"Mo, are you okay?"

Looking at Dugu Mo who had no strength at all, her heart was as sharp as a knife.

He tried hard to break the iron fence in front of him, but he couldn't exert any strength.

The deafening sound pierced her chest like poisonous needles, seeming to prick her heart into holes.

"Yun'er, don't exert any effort. It's no good. This sound can not only make you feel weak, but also make you miserable."

Dugu Mo clung to Liu Yun tightly.

"Quick, leave before you completely pass out from the pain."

Liuyun couldn't help but shake his head, and when he turned his eyes and saw Leng Jianfeng and Protector Feng who seemed to have fainted inside the iron bars, he couldn't help but feel tight in his heart.

How much willpower does it take for her Mo to persist until they arrive?

"Yun'er, hurry up, leave quickly, otherwise you will all faint here. Mother-in-law and the others have been taken away... Go and save them..."

Dugu Mo pushed hard with his hand, trying to push Liu Yun away.

Liuyun gritted his teeth, and when he turned around, he saw that Yu Wuchen and others were also sweating profusely, and they were in so much pain that they couldn't exert any strength.

"Tick tock tock."

Liuyun followed the sound and saw something like a copper bell swinging continuously beside the window sill.

This sound was obviously made by the copper bell!

Liuyun's eyes darkened and he stumbled over. Yu Wuchen and Chu Tianxiang also discovered the copper bell and ran over at the same time.

I grabbed the palm-sized copper bell, but I couldn't pull it off.

Chu Tianxiang and Yu Wuchen couldn't move for a long time, but on the contrary, the voices became louder and louder!

"No... I'm afraid this thing can't be pulled just like the stone door."

Liuyun stopped the two of them from trying anymore, and when he pulled him down again, they were all stunned by the sound!

Chu Tianxiang immediately swung the Dragon Black Saber, using almost all his strength to slash at the copper bell.

There was a "bang" sound, and the copper bell swayed a few times, but it was still hanging there intact.

"ah……"

Xin'er was so shocked by the sound that she cried out in pain, and her whole body was shaking like crazy.

Dugu Xing hugged his heart tightly to stop her shaking body, his heart full of distress.

The bells continued to ring, and they couldn't hold it any longer and slumped down one after another.

After Xin'er screamed a few times, she waved her hands and the lute fell from her sleeves.

When it hit the ground, it immediately turned into a normal piano, emitting a burst of green light.

"Qin..."

Xin'er shouted and stretched out her right hand to grab the piano, but it hit the strings.

There was a "crack" sound and the piano rang.

But at that moment, the sound of the copper bell seemed to vibrate. If you don't pay attention, ordinary people can't detect it at all.

Several people were shocked at the same time, and they all saw the surprise in each other's eyes when they looked at each other.

"Xin'er, can you still bear it? Come on, play the piano quickly."

Liuyun shouted to Xin'er.

Dugu Xing immediately held his heart and asked her to sit there.

Xin'er saw Qin beside her legs, closed her eyes, and seemed to have spent a lot of effort before reaching out.

"Ms. mist mist..."

When the piano started playing, it was a little messy and out of tune at first, but after a while, the music became more and more beautiful, and the sound struck everyone's heart.

The sound of copper bells and piano are intertwined, one is good and the other is evil, fighting hard.

Everyone took the opportunity to quickly meditate and adjust their breath.

But Xin'er actually played harder and harder, seeming to have driven away the pain in her body, and the tunes sliding over her fingertips became more and more exciting.

Until everyone regained their strength and opened their eyes, their hearts were still beating, as if they couldn't stop.

Suddenly, a white light flashed and rushed straight towards the copper bell.

With a "bang" sound, the copper bell actually fell to the ground this time. After bouncing a few times, it instantly turned into pieces and scattered golden copper shavings all over the floor.

"ink."

Liuyun was overjoyed and stood up.

Seeing Mo holding the Meteor Sword over there and his father and protector Feng, who had also returned to normal, he finally let out a sigh of relief.

"Xin'er, it's okay."

Dugu Xing called softly, but Xin'er finally stopped and stopped the last note.

The sound of the piano stopped suddenly, and the copper bell did not ring again.

"It turns out that the green harp is used to deal with copper bells."

Protector Yu secretly clicked his tongue.

Xin'er still seemed to be in a dream, and it took him a long time to come back to his senses.

Seeing the Luyiqin in front of me and everyone who was already safe, I couldn't help but clicked my tongue and quickly took back the Luyiqin.

"This is thousand-year-old black iron. I'm afraid only thousand-year black silk can cut it."

Protector Feng, who had woken up, touched the iron fence in front of them and frowned.

"I have already tried the Meteor Sword."

Dugu Mo shook his head, saying that the Meteor Sword didn't work.

The three men were imprisoned within the bars and had obviously tried everything.

"Princess Huarui and the Holy Emperor were also locked in a cage made of thousand-year-old black iron. Without a key, it cannot be opened at all."

Protector Feng continued.

"Can't the Dragon Black Sword also work?"

Chu Tianxiang had already taken out the Long Wu Dao and slashed the iron fence with a bang!

"Bang."

The knife collided with the iron, sparks even flew out, but there was not even a hole in the iron fence!

"Hahahahaha. I advise the juniors not to do useless things. Even if you have the four great artifacts, you still can't open my thousand-year black iron!"

Suddenly, a dull shout came from above their heads, the voice was hoarse but extremely arrogant.

"It's the Great Elder."

The two protectors Yu Wuchen and Feng Yu spoke simultaneously.

"I will reunite your family today!"
