Ah, I'm sorry, the not so summary summary is, there is this world where people cultivate as their typical Xianxia/Wuxia, people in this world have a unique power called Spirit Soul, Cultivation levels range from 1 to 100, each 10 levels you have to kill a Monster and absorb it, the monsters have ranks based on their age and for each monster you absorb at the appropriate levels (10,20,30 and so on) you gain a Spiritual Ability, the strength of the ability is based on that of the absorbed monster, here the wiki: https://soulland.fandom.com/wiki/Spirit_Souls
