How to code all blocks Broken on a pickaxe.

I was recently making a code in MCPE for blocks broken on pickaxes and it didnt work. I am hoping someone could give me a full code (not plugin) about how to get blocks mined on a lore

 

So You Want It to Track How Many and What Types Of Blocks Have Been Mined By The Pickaxe and For it to be Put In The Items Lore. Or Do u Want The Pickaxe To Break A Certain Blocks Which Is Stated In The Lore.

 

I want to track how many blocks have been mined with a certain pickaxe and put into a lore

 

Create an a new NamedTag Entry on the pickaxe and use it to store the number of blocks broken. Increment that every time a block is broken. After that, you can update the items lore with the value on that tag
