Suggestive

Genjutsu is all about manipulating someone's chakra and since our mc has less experience in chakra control than Itachi who is a genius in regards to a lot of things, most prominently his genjutsu, it will be hard to break free from his control.

I won't be going to ham on cultivation techniques. He won't be meditating to increase his chakra storage or comprehending the dao. I will just translate some techniques into jutsu's like movement techniques. You can think of qinggong as Tsunade's chakra enhanced strength but applied to the legs.

True, my big dumb brain hurt.

I just want to give him a motive to get stronger and stop treating the world as if its all sunshine and lolipops.

Wait a little cuh.

He will avenge his family but by going for the true masterminds.

It'll be different, I promise.

He won't be following the path of the original sasuke. He realizes that something else is going on and will be purging the village of its evil in pursuit of the truth.

Unsure of who the female protagonist will be yet but it definitely won't be happening soon.
