Kaen opened his eyes as he scratched the back of his head in embarrassment: "Sorry, I don't know why it shattered?"
Headmaster looked at the broken shards of the crystal sphere in shock before shaking his head as he rejected the theory he speculated.
There were two reasons a crystal sphere could shatter like this. First, you feed it more mana than it could handle and the second being that the Crystal Sphere was already broken from the inside and had shattered at this time.
Headmaster had speculated the first theory which he rejected outright.
How could a 4th-rank mage have the mana capacity to break a Crystal Sphere that could hold the full amount of mana of even an 8th-rank archmage?
Therefore, declaring the second theory as the reason, the headmaster shook his head, speaking: "No, It's not your fault. This crystal was defective that's why it broke, there is no need for you to apologize"
