In Naruto Universe, time travel to become Naruto's sister

"Okay, Green Pool, calm down. No need to panic. You've just been reborn as an unborn baby. Nothing special... right? After stumbling into a new environment, the first step should be to gather information about what's going on around you, but as an unborn baby, I don't have much means to do that right now. Listening to my parents might be useful, unfortunately, my ears aren't quite developed enough to do that. Forget it, I'll practice first."

So for the next few weeks, Green Pool meditated.As a fetus, physical cultivation seems to be difficult at present, but spiritual cultivation is a breeze.Compared with the physical body, the soul can still be cultivated in advance, and there is no harm in it. The more mature the soul, the more beneficial it is for future cultivation. The earlier the person who starts to cultivate the soul, the higher his achievement will be.

In just two months, Green Chi's soul has matured to three years old. Her previous experience and superb skills naturally played a huge role in reaching this ridiculous speed.

Now that her soul has matured a little, she can... and still can hardly do much more than before, except to access her state of mind.Usually, it takes some practice for someone to get into it, however, those who have done it before can easily master the means.This naturally includes green pools.

After a little concentration, she felt a familiar pull and found itself entering her mind.A dull atmosphere.Metal pipes protrude from the walls and ceiling, and water slowly drips from them.The dirty-looking ground was reinforced with brown bricks, and a stream of water flowed steadily alongside the brick sidewalk.In other words, she seems to have fallen into a pothole.
'Shit!What's up with this shithole?What happened to the vast mountain in my previous life?My glacier.My snowy forest?Is it possible for me to change all this once my soul reaches the proper level.Seriously, what's up with this weird physical manifestation of the soul?Is this for everyone here, or just me?Probably to everyone, because I don't think it has the slightest connection to me.Now, let's explore.Perhaps there will be some interesting discoveries here.

In this way, Lvchi began to explore her state of mind.Some might think this is redundant, after all what is the use of exploring your own mind?This is definitely not the case, after all, many things are hidden in your own heart.As if to confirm this belief, after just 30 minutes of exploring, Greenpool did find something she hadn't noticed before.Obviously there should be something, but Green Pool never thought too deeply about this possibility.That is a connection to another mindscape.This is the state of mind of her new mother.

"What a strange thing this is. How can an unborn child have a mental landscape. The soul is too young to form a mental state. However, I did it. Before I was born, my soul can reach a certain maturity. For ordinary people, this is usually impossible. After all, a normal child, no matter how talented, is impossible to cultivate in the mother's womb. But for me, this is easy. After all, I still have the memory of the previous life. This has led to these interesting phenomena. The spiritual landscape of mother and child The direct connection between the two. Pretty sure this will be lost after the umbilical cord is cut, but for now, let's keep exploring. I might see some useful memories from my mother. Maybe I can at least know what level this realm is."
