Help Me + My Weapon

Hi I am new to game and would like to know what are the steps to be able to make my wep go from+0 to +9....Step by step please

Depending the level of your ancient weapon is the grade and amount of crystals you require. Right now you can't get a +9 weapon with just crystals after +5 you'll need preservation stones so if it fails it won't break your weapon or armor.
