The vast Eastern Sea roared with turbulent waves.
Song Lin and Ying Zheng flew over the sea surface.
"Why did you change your name? Your appearance has also changed," Song Lin asked.
Moreover, Ying Zheng's current body didn't seem to be his original one.
"It's a long story. As a disciple during the Eastern Han dynasty, I cultivated the seven beads of heart, liver, spleen, lungs, kidneys, brain, and eyes. Later, the seven beads merged into one, making me the Underground Master."
An Underground Master signifies eternal existence without the need for Taiyin Refining, though one cannot leave Lishan. It's a state coveted by many cultivators.
But what sort of person was Ying Zheng?
Even as Emperor, he aimed to be the most formidable one; naturally, he wouldn't settle for being a mere Underground Master.
And so, he painstakingly developed a method of Cicada Transformation and Rejuvenation over many years.
