Review Detail of antmanFN in Shadow Slave

If your planning on reading this novel let me warn you about some things the story progresses painfully slow so if you don't have good patience then you should move on now for what i think I myself dont have a lot of patience but kept pushing through because i usually enjoy stories like these and i thought it has to be in top 10 for a reason so now im on chapter 145 and I have 3 things I need answred or just dont like about the story the first thing is obviously plot pace ive seen slow plot before put they usually all pay of atleast by chapter 100 but yet so far i dont think the mc is even in the discussion for top 20 strongest sleepers secondly the power system is a litlle confusing the mc has divine rank aspect and i understand that it increases potential but so far i think thats its only use it dosent give him a boost or advantage in any way not even against soul or mind attacks since im pretty sure it correlates with atleast his soul it dosent give him more strength than the average sleeper nor does he get a few extra points from consuming shadow crystals so far its proved usless and i just wonder whats its use
