His martial spirit turn out to be female and she is imprisoned in his body (so she is his martial spirit but not his power other spirits are one of the power of host but ye zifeng can't use spirits power without his spirits permission so he can only borrow that power and that mean his martial spirit not actually his) after talking ye zifeng proposes making a blood contract she is going to help him until he reaches martial practitioner and after he became one he is going to find a way to free her. I don't know what happens after that because I dropped it
First of all I found his third astral soul choice is very bad
He can go to 6th layer but he thinks just because he communicate little bit he choose it from 5th layer after that except for turning half monster (this isn't come from astral soul it comes from technique that king cang left not related to this astral soul) he uses its special tecnique (summoning the beast) few times.
Then for fourth astral soul he goes to 6th layer then he sees a sword he never used sword before (maybe used few times?) but he makes his fourth soul a sword then he goes to learn sword. His talent for swords is very good he learns swordmanship will (when you learn something very well you got will of it. İTs like you use fire after you breakthough to yuanfu realm you can start to learn fire will) after he learns all these he stops using sword he goes to halberd he uses sword techiniques with halberd he uses his sword soul with halberd after 400ish chapter to 650ish chapter I didn't see him using sword even when his life in danger (Note: at the 650ish chapter he takes a demonic sword. I assumed that he will use sword from now on there is hıgh chance that he may not be using even after 650 700 ish chapter).
For his fifth soul he goes to 7th layer and make one of the souls in there his the problem is there are few people makes their fifth soul from 7th layer. He who comes from immortal realm (or someting like this) has same level astral soul as someone from this world for their fifth soul like ı said from top he should never start with 5 th layer he should strat with 6 then 6 7 7 and for the fifth soul 8th layer or starts with 5 then 6 7 7 again for fifth soul 8th layer. İT shouldn't have happened like how its right now.
