Hey, so im looking for a novel where the MC is either in a time loop like in mother of learning or is kinda frozen in time like at the beginning of Everyone Else is a Returnee. I want the MC to try to get stronger/smarter/better during the loop/frozen time. I dont want there to be anyone else with the MC in the loop/frozen time at least at the beginning, i dont mind if it changes later on. MC should start weak but get really strong with time. and yeah already read Mother of Learning and Returnee.
How about fanfic? AU naruto world with MC sakura. Pretty well done timeloop with bonus mythological existences in world. Time Braid - completed You can't go weaker than sakura pre chunin exam beginning :*
Your loss, it was well done. But to each their own, good luck with finding good good loop, there aren't many. https://www.royalroad.com/fiction/18619/timetravel MC can (and automatically before death) travel back in time. Not exactly what you wanted, but has some parts. Not sure about latest 20 chapters but first 40 were relatively interesting.
https://www.novelupdates.com/stag/time-loop/ I recommend: Re:Zero Kara Hajimeru Isekai Seikatsu (Web novel is translated online) Utsuro no Hako to Zero no Maria (you can download volumes on other sites)
https://www.novelupdates.com/series/utsuro-no-hako-to-zero-no-maria/ This novel is very good, but the only similarity of this story fo your preferential is that it is Time Loop for "over 9000 TIMES", but he is not alone in this time loop...
