Linglong’s First Battle 

On the Tianyuan Sea, Yun Zizai descended alongside Yun Feiyan.

"Master, would this world have my opponent?" Yun Feiyan asked in a melodious voice as she looked around. She frowned. "What a rich death aura shrouding the entire place. It seems to have condensed into evil cloud mist. This world must have experienced the deadliest massacre in which even many Quad-Sages, and an unknown number of living things were killed."

"I've just probed into the past by reading the core of the world and learned that the Abyss attacked the heavenly realm a few decades ago. It has caused the collapse of the Heaven Court while the Abyss is almost destroyed."

Yun Zizai could only check the major events that happened in the past but not the details. He could deduce the details only with his Saint Dao method if he was to understand some people and things.
