Review Detail of Vamovelo in Shadow Slave

U know. Im searching for novel that contain shadow clone Jutsu which have shadow clone that can be used to learn anything without the user directly learn it. But i stumbled upon this one... Just read a few, wanna stop because so many description few dialogue,but see its no.1 in rank, im curious. I know that flaw is good to twist the story a lot. Im sad.. I tho the mc gonna be weak to strong n reach the top without something being of a slave. I kinda feel empty when i read after that vol2. What the point of u become strong n stronger but, u r a slave. You r not in control of your own choice. Even tho his master let him do as he will. But in crucial choice she forced her will on him not his free will.... This... Damnnnn hahh.. Wanna read the next n next but sad... I dont like slavery. For writing quality is it just me, when i read this novel, my stomach kinda churn, particularly when the author always change the name of nephis to her true name. That happen often with different character name too Ugh...
