Well it's in updating phase so sorry for inconvenience in reading. NOTE- The real story of absolute manipulation and power dynamics will start from when Mc would get reincarnated in immortal world, until then enjoy the primitive setting and ignore if you find something illogical because it was primitive world not modern world. So be kind enough to not judge before reading significant chapters as early chapters might be bit bad.
