Gu Da stared blankly, then lifted his hand to pat the top of his brother's head, as Gu Er rubbed his own head affectionately against Gu Da's palm.
Though the brothers seemed inseparable and at peace with each other, the moment Gu Er lowered his head, the shadow in Gu Da's eyes could no longer be concealed.
He desperately wanted to kill him with a single slap right then and there, but the time was not yet ripe.
Gu Er was wearing a Supreme Protective Talisman. If Gu Da couldn't shatter it with one slap and kill him at the same time, he would no longer have the chance to avenge Ajin.
He must gain his brother's trust in a short time; otherwise, once Gu Er developed his own power base, Gu Da would never see his day of ascendancy.
"Brother, you should rest for a while, I'll go check if the medicine is ready," Gu Er said considerately as he tucked in Gu Da's blanket, then turned and left the room.
Whistling a merry tune, he made his way to the kitchen, feeling quite elated.
