Well this is my 1st ever book , I ever been written online and if there is any problem , watch if you want or not because I am write it for fun and about errors in language just think about an 9th or 10th class student writing an essay for an class, but there will be no problem in logic of story that I will guarantee.
Well about the adopted girl in the story ,her martail spirit is golden flame eagle and cultivation level-15 at the age of 8 year old with an innate soul power level-8 as for why she cultivation that fast you don't think Mc will not give her any resources and her mimic training is in fire or open sky area or both and in early state of cultivation is very easy for high innate soul power levels to cultivate and her 1st ring is highly compatible with martail spirit and its super age ring for 1st ring which give her level-13 soul just after obtaining it and Mc give her an treasure which improves physic somewhat.
Mc is 15 year old have innate full soul power level and currently finding his 5th soul ring, he absorbed super age soul ring except the 1st soul ring , so that why he has very high level of cultivation for his age and he only have about 14 subordinate in which except Anne all the other are sent by him in all the important and powerfull force's as a spy for some information and for his future plan.
I made Mc somewhat stronger them other as he doesn't have any system or golden finger.
