Mira didn't need the Guardian to help her leave this place now that she was in full control. All she has to do is think about leaving and she'll be teleported back to where she entered this place.
The Guardian didn't say anything to her as he watched her turn around to teleport out of this place. He kept the same carefree smile on his face, but underneath it, all his feelings were complicated. He was happy that a successor was finally chosen, but he also knew that things would've been much easier for Mira should she not have become the Successor.
She could've cultivated freely without too many troubles except for those she caused herself or those sent by that so-called 'god' that's been messing with her. Eventually, she would've ascended into the Immortal Realm where she would go through similar experiences, just on a different scale.
After a few thousand years or so, she would've reached the level where she could finally take revenge and settle down for a bit. She could find a place to rest, have a family, and live a happy life for the rest of her days.
Her journey would have still been long and arduous and even if she died again, he was sure she'd find a way to get back up and try again, but eventually, she'd achieve her goal.
That's why he's feeling complicated about Mira becoming the Successor. Now that she has inherited The F.LD.I.L, her journey will be anything but easy and it'll stay that way until she reaches the absolute peak an existence can reach. Either she becomes the strongest existence that anyone and anything can reach or experiences eternal damnation. There are no other options.
However, there are also plenty of benefits that come with something that's such a high risk. First, her potential has skyrocketed, so much so that she now has the potential to reach that kind of power. Second, everything in the F.LD.I.L are unique treasures that don't exist anywhere else. The Infinite Garden is just one such example. Such a thing can only be found in the F.LD.I.L.
Third, Mira has access to all kinds of ores, herbs, materials, resources, alchemic recipes, weapons, armor, etc. Even stuff that can't be found in her world or that's so rare in her world that only the major powers have access to it, she'll be able to acquire it so long as she works for it. That in and of itself is priceless because that means even if she doesn't join a Sect or any sort of power, she'll still have access to resources. Sort of… For most of the common resources, it'll be much easier for Mira to obtain them as long as she joins some sort of Sect.
There are many more benefits to inheriting the F.LD.I.L, but most of those won't start showing themselves until later on in her journey.
Fortune in misfortune perfectly describes Mira's situation right now because while her life will probably suck for a while, her growth rate will explode along with her new potential. However, that's not what's making the Guardian feel so complicated.
What's making him feel so complicated is thinking about what Mira will become after achieving her lifelong goal of killing the man who has caused her so much unwanted pain and suffering.
Will she be able to keep moving forward or will she break when she realizes that her revenge means nothing to The F.LD.I.L?
Shoving those thoughts to the back of his mind, he watched as Mira finally disappeared and returned to the area where her friends are.

Mira was finally able to leave that hellhole and when she was finally teleported outside before she could even look around she felt the ground around her shake. Then after a few seconds, something flew into her Soul Sea.
Mira knew exactly what it was, but just in case something happened she decided to check it out.
When she looked in her Soul Sea, she saw her Scythe floating there, and right beside it she saw a dark and ancient looking castle that released an aura of death around it. She knew right away that this is The F.LD.I.L. Looking at it, Mira could also feel that she could teleport back inside whenever she wanted to.
After she finished checking out her Soul Sea, she was finally able to get a good look around her. She wasn't surprised to see that the unique biome that was filled with bone trees, poison fog, and poison dirt was now gone, and in its place was a grassland full of life.
However, all of a sudden she felt 3 gazes fall on her and she knew exactly whose gazes those belonged to.
She turned around and saw Maria, Celaine, and Elenei looking at her with their weapons drawn and vigilant eyes, but for some reason when they saw her face, the 3 of them froze.
Mira was a bit confused why they were looking at her almost like they didn't recognize her and it wasn't until Maria started screaming did she finally understand why they didn't recognize her at a glance…
"Kyaaaa!! Is that you, Mira?! Oh my god! You look so cute!! Look at how small you are! What happened in there that caused you to become so irresistibly cute!? Well, not that I'm complaining. I much prefer this Mira versus the mean teenager Mira! Hehehe~ Even with your emotionless face, you still look so cute! Oh! Just look at your clothes being a bit too big for your current size! You look just like a child who wanted to wear her Mommy's clothes! Hehehe~"
Maria wasted no time running over to her and examining her body. Mira could've jumped away from her to prevent this humiliation, but it was only after she left that place did the built-up exhaustion finally hit her.
Right now, she didn't have any energy left to spare so she could only grit her teeth as she let Maria pinch her cheeks, hug her, and even mess with her hair. Soon, her eyelids started becoming heavy, but before she passed out, she decided to say a few words to Maria to let her know she's fine.
"Talk later. Need… Sleep."
"Mira!"
