If you are looking for places to visit, you can explore countries like thailand, vietnam, dubai etc. 1 lakh is more than enough for a trip to any of these countries.
I’ll try to list down some good material things you can buy if not travel
If you like space or stargazing etc, you can get a good telescope for 70-80k, its something i have been planning to do but never got to it.
You can buy a movie projector, one of my friends has it, we go there to party often, its fun to get drunk with friends and watch movies on a projector
I have also spent quite a bit on interior design, but thats just cause i am quite an introvert (you must have guessed by my suggestions), so you can think about it if you fancy that
I am guessing if you were into gaming like I am then you wouldn’t have even asked this question so wont recommend anything in that area
