Capítulo 688: Sword Saint's Letter of Challenge

Gai Tianjiao caught up from behind and spotted Zhang Ruochen standing at the foot of the altar. Looking curious, she asked, "What are you doing, junior fellow apprentice Lin Yue?"

Zhang Ruochen's Spiritual Power rapidly flowed back into his body like a stream of water.

Zhang Ruochen retracted his hand from the altar, turned around, and glanced at Gai Tianjiao. "Nothing, really. I was just curious as to whether this Jade Stone Altar has been standing on Ancient Gods Mountain since ancient times, or if it was built later on."

Unthinking, Gai Tianjiao said, "This altar was used in the ceremony to worship heaven during the Sword Technique Conference. Its renovation 500 years ago required the mobilization of a huge amount of materials and manpower. To this day, millions of Spiritual Crystals are still required annually to maintain the array at the foot of the altar."
