Facing Zhang Bairen's words, Chen Changsheng did not answer and merely continued treating his injuries.
Seeing this, Zhang Bairen continued, "During the Ascension Road War, Chen Shisan unleashed that Heaven-Shaking Sword."
"Back then, I already noticed that something was wrong with Chen Shisan."
"But at that time, the path of the Bitter Sea System was still unclear, so I only thought that he had reached extraordinary heights in swordsmanship and found some secret of the Bitter Sea System."
"But later, as the Bitter Sea System was perfected and the Extinguish Heaven War erupted, I realized that I could no longer see through Chen Shisan's realm."
"During the Extinguish Heaven War, he even slew eighteen Heavenly Emperors and one Great Emperor with his sword."
"With achievements like that, could he have done it through insights into swordsmanship alone?"
"I am an outsider to Chen Shisan. He would never tell me about his exact realm or insights."
"But you are his master, and practically his half-father. You must be the one who understands his condition best."
Watching the look in Zhang Bairen's eyes, Chen Changsheng pressed his lips together and said, "Little Thirteen's realm has always been a mystery. Countless people throughout the world have been guessing what realm he reached."
"Some say he is a Heavenly Emperor, some say a Great Emperor, and others say that he has already become the strongest person of this era."
"But in this world, only two people understand Thirteen's true realm."
"One is the already-deceased Sword Immortal Meng Yu, and the other is me, Chen Changsheng."
"Then what realm is Chen Shisan in?"
Zhang Bairen asked anxiously. Chen Changsheng looked at him expressionlessly and said, "Little Thirteen's realm has always been stuck at Immortal King Ninth Grade."
"Immortal King Ninth Grade? How is that possible?"
