Fang Yun's eyes grew brighter. Anything whose very name could not be heard possessed tremendous power in its own right. Unless one became a Great Scholar and could touch the fringes of the Sacred Way, one was not merely unable to use it-one was not even worthy of hearing about it.
Take the Ancient Star River Tributary: people had heard its name, but could not remember what it actually was, because even if they did, the power of the Ancient Star River would soon erase that memory.
The Ancient Star River itself harbored no murderous intent and did not harm people, so it merely erased their memories. But from what Lang Kang had said, Fang Yun knew that whatever he was about to name likely harbored murderous intent of its own. Not only would the listener suffer an attack, but the person who spoke its name would also be attacked.
Fang Yun thought for a moment, certain he could withstand that power, then said, "I can give it a try."
Lang Kang said coldly, "Do you know what happens to newly ascended Great Demon Kings who hear those four words? Some lose their hearing, some lose their sense of smell, and the unluckiest lose their sight, unable to see anything."
"That is because they are weak." Fang Yun's tone was indifferent.
"Since you are so confident, there is no need for me to offer any more well-meant warnings. That great secret concerns the Head of Heaven."
The instant Fang Yun heard the words "Head of Heaven," a buzzing erupted in his skull. Then his entire body lost all sensation, leaving him motionless. He felt as though he were in another space and time, where countless streams of black mist descended from the sky, each wisp heavier than an entire world.
