Zhang Mengyao, being a bit more cold and aloof, remained silent.
Su Yu observed Zhang Mengdie, slightly curious, and asked softly, "Junior Sister Mengdie, is my master a longtime acquaintance of Elder Six-Tail Fox?"
Zhang Mengdie and Zhang Mengyao paused in their steps, their expressions slightly odd.
"Uh."
After some hesitation, Zhang Mengdie finally whispered, "I've heard, only heard mind you, that my master received fair treatment from Senior Tianyu in his youth. But later, for some unknown reason, Senior Tianyu disappeared for a while. When he reappeared, he seldomly left the immortal sect."
"While practicing spells, my master often used him as a target. Ahem, my master excels in illusion techniques, so it's normal to conceive imaginary targets."
Su Yu glanced at Zhang Mengdie and Zhang Mengyao, curious, "So, both junior sisters are also pursuing illusion techniques? What's the difference between an illusion technique and an illusion array?"
