Rainbow Core?!

Zhang faced the proctor… 

Was he worried? A bit, but he would never show it! Besides, Teacher Gale was watching over them, so he had to prove worthy of being his #1 Disciple! 

Thus, he resolutely stepped inside the glowing magical circle! 

"Zhang, right? Let me explain this real quick…"

The proctor quickly gave an explanation, mostly for the new students' sake. The intricate magical glyphs all over the azure circle? Those would test one's Magical Power! 

Then, the circles all over it would read this power and light up. The test was as straightforward as could be: the more circles lighting up, the better. 

Now, all Zhang had to do was channel his Mana… 

"Please go ahead whenever you're ready!" 

— GLOW! GLOW! GLOW! — 

As Zhang focused, the magic circles started glowing more and more. As for what he was channeling? The very Mana that he had gotten from devouring food all this time!
