Mountain Mover Great Sage spoke in a low, eerie tone, spitting out a secret passed by word of mouth among the Great Sages, one word at a time.
"Dao Ancestor Taishi?"
Zhong Shenxiu was puzzled. He truly had never seen that name in any classic. It seemed to have been forcibly erased by some supreme power.
"Dao Ancestor Taishi was the founding patriarch of Taishi Mountain. He attained the Dao very early, and furthermore... proved the Dao and ascended long ago. But for some unknown reason, a thousand years ago, during a sacrificial ceremony held as usual at Taishi Mountain, Dao Ancestor Taishi, who had long since ceased responding, finally gave a response. The result, however, was... a great tragedy!"
"Nearly every cultivator covering the mountain underwent Dao corruption. From then on, the Dao lineage of Taishi Mountain was severed, while the mortal world gained another Heavenly Demon Battlefield."
Mountain Mover Great Sage's tone fell.
"Dao Ancestor Taishi should have been in a realm above the Great Sage level... Dao corruption? What did he become after undergoing Dao corruption?" Zhong Shenxiu was shaken. For no apparent reason, he sensed something beyond the world, some existence coveting this world...
A mere wisp of its silhouette filled Heaven and Earth. Its lines were savage, like the Great Dao itself.
Light burst from Zhong Shenxiu's eyes. The [Taiyin Corpse Release Talisman] within him trembled slightly, transforming into a streak of light that severed this inexplicable connection.
I'm a Great Sage, after all... If it had been an ordinary cultivator, they probably would already be dead.
He pondered silently for a moment before Mountain Mover Great Sage's voice reached his ears:
"When a Great Sage undergoes Dao corruption, they become a Great Fiend!"
"When a Dao Ancestor undergoes Dao corruption, they become... the Supreme!"
