Even He Lianjue, who was always the most composed and calm, showed a hint of surprised and bewildered expression in his eyes upon hearing the Demon Lord, who made all six realms tremble with fear, call him "big brother."
But he soon regained his composure!
Now that he had reincarnated as a mortal and lost his memories, it was normal for his temperament to change.
He did not show any hostility towards Gu Tingyun, just nodded his head lightly.
He did not like the Demon Lord Ling Chenyuan either.
Even though he had sacrificed himself to save his little sister, it still couldn't change his thoughts.
Back in the six realms, he had always been reluctant for his sister to be too entangled with the Demon Lord, because Ling Chenyuan was a Devil Dragon born from the Demonic Qi in the Demon Abyss, innately fierce and brutal!
And given his unpredictable temper, he feared that his sister would be in danger if she stayed with him for long.
