The 'time conversion' mentioned by Old Yao is actually a euphemistic term for 'manipulating time'.
After all, the Alliance is also a respectable institution, and the word 'manipulation', no matter in which dimension, always carries a bit of a villainous vibe inherently.
Specifically in this situation,
time conversion should specifically refer to the sub-field of 'time reversal'—by reversing time, allowing the two young wizards to have enough time to double major in multiple subjects, without even sacrificing their sleep time—Zheng Qing was not unfamiliar with this concept, and as soon as Old Yao mentioned it, he grasped the deeper meaning.
It's just that in his impression, this doesn't seem to be an easy matter.
Nor is it safe enough.
"I remember that reversing time can cause spatial folds... Repeatedly 'adjusting' time seems to make this space collapse prematurely? Isn't it rather unsafe?"
