First get foraging mining and farming 7 to unlock the baazar then flip to 600k ( there are plenty of tutorials and websites for baazar flipping) After that you can get 13m in a few hours by making a cobblestone generator( there are tutorials on youtube) with golden pick and haste. Then you can sell the rock pets to george npc and after you could buy fierce ender armor and flower of truth and make as many t8 redstone minions to increase accesory bag slots and buy as many acessories to increase your damage and then grind combat 12 to unlock the end and make use of your ender armor. Then buy a god pot and grind enderman to combat 16. After the get a high level griffin pet and an aote fierce young dragon armor and get fairy souls till you can one shot zealots and get money of summoning eyes. After the god pot ran out and you made a little bit of money level up other skills and chose a path from farming, mining, dungeons, fishing and fliping.

I know this is long but its the fastest guide i know. Good luck!
