The students understood why Jin had performed the technique before explaining it. If he hadn't shown them 'Space Pull' beforehand, then the students would have never been able to understand it correctly.
"Space Pull doesn't reduce the actual distance but once they render your perception of space itself, your life will end before you know it."
After reaching the end of this technique's explanation, Jin's lips moved but not the tiniest bit of sound left his mouth.
Jin created another barrier that covered all the students once again. This time, the 'Space Pull' was used by Jin instantly. The students couldn't even feel the gathering mana.
The students found themselves in front of Jin once again. They couldn't correctly guess the distance between themselves and Jin after they were pulled into the barrier.
'How did he cast it instantly?'
Rin was also like the other students who had forgotten about the basics that they were taught just a day ago.
