So he can't use his senses, but he knows a week has passed? WTF? This part needs reworking.
This soul was Alex's. Right After he died, his soul was transported to an unknown place. It has been a week since his death and he has yet to see anything. Actually, he couldn't even use any of his five senses.
Honestly one of the best novels on this site - it has everything - epic battles, a kick-ass MC, who very fast becomes OP, but still has more powerfull enemies, a good sense of humor, good worldbuilding, fleshed out side characters...
I'm quite amazed that is not in top 10 of this site
