In fact, Du He wasn't the only one whose voice had changed. The teachers and students present were so agitated that their bodies trembled.
If they trembled even more violently, people would probably think that they were having epilepsy.
"No."
Mu Tianyan's answer was very concise, making Du He and the others so anxious that they wanted to hit him.
"Ah Yan's array formation technique hasn't reached the Earth Realm yet. The reason why these two large array formations became low-level Earth Realm is because I drew a strengthening inscription on the array flags."
Seeing that Du He and the others were so anxious, Lu Zijia could only answer for her man.
"You drew a strengthening inscription on the array flags?"
Du He's old eyes suddenly widened a bit more, and his eyes were about to pop out. "So, you're still an inscription master?!"
As Du He guessed, the teachers and students behind him gasped in shock.
