After arriving at the immortal caves, Song Ling'er asked the disciples there for their story.
"That person touched the immortal cave and disappeared the next second!"
"It was so sudden! He hasn't returned since then!"
Song Ling'er frowned at the situation, and she began looking around the Zither Goddess' immortal cave, even touching the exact same spot that Yuan had touched, but nothing happened.
"Oh, I forgot to mention this, but he played a song with the Soul Ensnaring Zither before touching the immortal cave." Ai Wan suddenly said.
"Why didn't you tell me this first?!" Song Ling'er sighed.
"Do you know what kind of song he played?"
"No, I have never heard of such a song before."
"Can you replicate it?" Song Ling'er then asked.
