Emerald Sternum
Unless one was able to use the surrounding Spiritual Energy by themselves, the energy around them would only help them to get rid of any injuries and fatigues in the body, and though their body would still be stronger than any usual human and would have a lot of energy stored in them.
It would still be useless unless they were to cultivate on their own by directing the Spiritual Energy throughout their body and strengthening their organs and quenching them in the energy thus making it stronger.
Though her body would have a lot of energy, Yuan Meng would still find it hard to deal with some thugs unless she were to start cultivating.
That was the same as if she was to face some men, though she would be able to make them black and blue, with no way to control the energy in her she might injure herself in the situation as she didn't know how to direct the energy which she might use subconsciously in her movements.
