Isaiah slowly opened his eyes, and the starry sky came into view.
"Teacher." A respectful voice sounded beside him, "You've awakened."
Isaiah turned his head and saw a middle-aged woman kneeling beside him, dressed in a jet-black celestial robe, gently speaking, "Mina, have you been by my side all this time?"
"Yes, teacher." Mina nodded, then said with a hint of puzzlement, "You didn't seem to be resting earlier; I could sense you entered into a very mysterious state, but Cheng Xin told me it wasn't dangerous."
"Oh, yes." Isaiah touched his star-sea-like right eye, "It was indeed a very wonderful experience."
"...You look very happy."
"Is it that obvious?"
"Yes." Mina chuckled and asked, "I haven't seen you with this expression in many years. Can you tell your student the reason?"
"Of course, my child." Isaiah slightly nodded, gazing at his student with his star-sea-like right eye, "Because... the other eye."
