The Tales of Draconic Warlock
Magnus was reincarnated in a magic world. He led a simple life on Earth and that was something he liked rather than being dragged into conflicts or into adventures to save the world or something like that. He never cared to be the MC but hoped that he would have a pleasant life, much better than his previous life. Whether he could or not, read the tales to see. ---
I returned to the academy
One month passed away like it was nothing.
Though I didn't train much, I have no regrets.
What do we train for?
It's to gain strength and what is its purpose, if not to enable us to live longer? Long life is so that we can spend more time with the one that we care about.
If we forget that and spend every minute only improving ourselves, then we might not be able to have what we should have.
Memories.
With the rank I am at now and the possible ranks that I can each in the future, I will live longer but that would be grown-ass me. I would miss out my childhood memories if I only keep increasing my strength and forget about other things.
Before I could graduate from the academy, I would become an adult ad it would continue to be so till my end. There is no way to reverse to childhood and enjoy the life as a child.
