Can someone suggest me something similar to Solo leveling or the beginning after the end ...

"Omnicient Reader's Viewpoint" and "A Returner's Magic Should Be Special" are the best recommendations I can give you:

"Tomb Raider King" is fun too, but the MC is very arrogant, so it can be a little frustrating sometimes.

I don't know if "Tensei Shitara Slime Datta Ken" is your style, but I love it. Just avoid the spin offs.

And "Ranker who lives a second time" is ugly but fun:

Thank you for the suggestions (⌒▽⌒)

I have read nanbaka but thank you (=・ω・=)

No problem! (⌒▽⌒) I hope you enjoy them! (￣∇￣")
