Chu Linfeng was momentarily stunned by the energy fluctuations emanating from the three purple crystal stones, "Sister Yue'Er, what kind of crystal stones are these? How can they have such powerful energy fluctuations? I feel they're even stronger than my Star Crystal."
"Those are Top-Grade Immortal Stones. Immortal Stones typically come in five colors, corresponding to four different grades. Low-Grade Immortal Stones are yellow, Middle Grade is green, Upper Grade is red, Top Grade is purple, and the rarest Immortal Crystal is completely transparent. These purple glowing ones are Top-Grade Immortal Stones," said Sword Spirit.
"Why is there only one altar here? I thought it would be a terrifying place with even stronger monsters. Since there are Top-Grade Immortal Stones here, does it mean the Ice and Snow Fairy's spirit is healing on this layer? And she asked me to collect these Five Elements Tokens to prove my strength to meet her?" Chu Linfeng inquired.
