The ones I have read with the exact same plot (zombie apocalypses + second chance) are mostly novels (some even with the same stones in zombies haha). So I can tell you those if you are interested.
For manga with those two themes you can try Last Human, Return Survival, King of the apocalypses (im very behind this one so idk how good this one is), Return to player is a new one on mangago too. If you only want the second chance/know the future/stuff like solo levelling type manga I have lots of reccs haha
Im binge reading apocalypse themed yaoi novels rn if u want, I can recommend some
Back to the Apocalypse - izz finished and was ok overall
Reborn Otaku’s Code of Practice in the Apocalypse - has very satisfying hording experience, my guilty pleasure
Boss' death guide - Im currently reading and I really like
Number one Zombie wife - ughh ending is really!!! I cried
Dominions end - Not yaoi but the best post-apocalypse I've read so far, It's very classic
he comes back and get so little leverage, because even though apocalypse just started others know about the crystals and have super human powers/abilities when his own team doesn't even have them? badly written plot, read much better ones with the same setting
