When he reached the fourth floor of the Demon Refining Tower, Ye Feng heard a gentle and beautiful piano music and a faint fragrance wafted in the wind.
The first two layers looked like unique barriers, while the fourth layer looked like an ordinary place, without the blue sky and white clouds, or the sea of hellfire.
There was only a large empty flat, a rosewood table, an incense burner, an old man with a sage-like demeanor, and an ancient and mottled guqin.
The old man smiled and nodded to Ye Feng: "Congratulations on reaching the fourth floor. Immortals who can reach this level are not simple. Their strength is at least higher than the third level of earthly immortals."
Ye Feng smiled: "Oh, I wonder what level of earthly immortal the old man is?"
"I am just a musician, not an immortal. Young man, you are flattering me."
I took a glance at the fourth floor and immediately saw the stairs leading to the fifth floor, which was at the innermost part of the fourth floor.
However, Ye Feng knew that it was not that easy to go to the fifth floor.
He smiled and asked, "Excuse me, can I go to the fifth floor?"
The old man playing the piano smiled and said, "Of course, go ahead."
Ye Feng was overjoyed. The first two floors were very mysterious, with things like the hell of fire and the creek and bamboo forest. Only the fourth floor was the simplest, as one could go directly to the fifth floor by taking the stairs.
He bowed to the old man playing the piano and said, "Thank you, goodbye."
"Brother, won't you stay and listen to a song?"
"No, I have other things to do. I'll listen to the old man play the piano when I have a chance later."
Ye Feng strode towards the stairs. Although he had a smile on his face, he was extremely nervous. For some reason, this old man playing the piano was more difficult to deal with than the flaming giant lizard and the masked warrior on the first two floors. Especially his calm and composed demeanor, which Ye Feng did not dare to underestimate.
When walking past the old man, Ye Feng thought he would be suddenly attacked, but the old man was just playing the piano. The sound of the piano was so melodious that Ye Feng really wanted to sit down and listen to a song.
Ye Feng walked to the steps and glanced at the old man again, and the old man smiled at him.
"Goodbye, old man, you are a good man."
"Haha, it's too early to tell whether he's a good person or not."
No matter who you are, just don't stop me from going upstairs. I don't know what I will encounter on the fifth floor.
Ye Feng climbed up the stairs. The old man playing the piano showed no intention of stopping him. Ye Feng was happy. How wonderful it was like this, peaceful coexistence, stability and harmony.
However, when Ye Feng climbed to the fifth floor, he was immediately stunned. He still heard the old man's continuous piano music. It was the fifth floor or the fourth floor, and the old man was still greeting him with a smile.
"Brother, why are you back again?"
Ye Feng was stunned and stared at the old man: "Old man, which floor are you on?"
“Haha, it doesn’t matter which floor you are on. That’s what’s important.”
Ye Feng gritted his teeth and jogged all the way to the upper floor. It was still exactly the same floor, with a table, an old man, and an incense burner.
"Haha, little brother, why are you back again?"
Ye Feng ignored the old man and ran three times in a row, finally stopping in front of the old man.
He realized that the staircase leading to the upper floors was fake and he was trapped in a loop. The old man seemed to be asking him to go upstairs, but he actually knew that no matter how many times he went up, he would end up back on the fourth floor.
Ye Feng sat down on the futon in front of the old man: "Old man, just tell me the truth. How can I get to the fifth floor instead of going back to the fourth floor?"
The old man smiled and said, "How about you listen to my song and I'll let you go to the fifth floor?"
Ye Feng was helpless. It seemed that the only way to go to the fifth floor was to listen to the old man play a song.
"Okay, I'm all ears, old man."
"Then you better listen carefully."
A tremolo sounded, the sound was continuous but the frequency was extremely short, like thunder ringing in the ears, which made Ye Feng feel restless and his blood was turbulent.
Sound waves that are invisible to the naked eye contain powerful energy, which is sharper than the dazzling sword light. They rush towards Ye Feng from all directions, and the momentum is no less than Ye Feng's Die Ran.
"Hey guys, wait for me here."
The spiritual shield on Ye Feng's wrist automatically defended itself when attacked, and a golden light surrounded Ye Feng.
Boom, boom, boom, sound waves continuously hit the defensive light curtain. Although they could not break in, they still caused Ye Feng to feel great pain all over his body.
Ye Feng understood that relying solely on the defense of the spiritual shield would not allow him to listen to the entire song played by the old man. With a dazzling sword light in his palm, he used a move called Wind and Rain in the Sky, and a sky full of sword light danced around him.
The sword light and the sound wave met in mid-air, and strands of energy waves surged in all directions, hitting the wall of the Demon Refining Tower and leaving deep sword marks.
Only then did Ye Feng understand why the fourth floor was so empty, because the tower spirit knew that the shock wave produced by the collision of his sword energy and sound waves would destroy everything, so there was no furniture here.
The incense burner was within the protection range of the old man's piano playing, but the sword energy kept slashing at the incense burner, chopping the sandalwood in the burner into several pieces.
The old man playing the piano was surrounded by Ye Feng's sword light. His long snow-white beard fluttered in the wind and his pupils were shining. He didn't look like an old man at all. His body was stronger than that of a young man and his aura was even stronger than that of a young man.
Ye Feng secretly marveled at the majestic aura of the old man playing the piano, and the old man playing the piano also secretly marveled at the power of Ye Feng's sword. The two of them, one playing the piano and the other with a sword, were evenly matched.
Ye Feng secretly rejoiced that he had just encountered a masked warrior on the third floor and his divine power was exhausted. However, at the critical moment, the burning energy absorbed from the demon king's demon pill replenished his divine power in time and also stimulated the power of the ancient god clan's bloodline, which was equivalent to performing two secret battles.
Suddenly, Ye Feng clenched his fists, and the sword shadows in the sky disappeared. The nine small flying swords merged into one, condensing into a five-finger-wide heavy sword shining with golden light in the air, and chopped down at the old man's head.
A look of surprise flashed in the old man's eyes, and his hands flicked quickly. A series of sound waves, like a roaring dragon, greeted the giant sword that was slashing down.
Boom! The incense burner beside the old man exploded into pieces. The old man's little finger trembled inexplicably, and the tail string broke. The little finger was injured by the string, and a trickle of blood slid down the broken string.
The music of the zither stopped abruptly, and the old man sighed: "After five thousand years, someone finally listened to my music."
"Old man, your piano playing is really amazing. I was lucky enough to win by half a move. I'm so sorry, so sorry."
The old man secretly admired and said: "Young man, you are very powerful. You have already passed two levels, and the power in your body is still as endless as the tide. You have passed this level of mine."
The old man lightly stroked the air with his finger, a golden light flashed, and a golden light flashed on the stairs leading to the fifth floor. A hot breath came from upstairs.
