Audrey planned to break through to level 20 and above in half a year to have some ability to protect herself in this world.
However, it was clearly not easy to make such a big breakthrough in half a year.
The path of cultivation was simple but complicated. One step at a time, and the further one progressed, the more difficult it became.
Just because Audrey was able to break through to Level 4 in a month did not mean that she would break through to level 8 in another month's time.
The progress of her cultivation was not a matter of adding up but a matter of multiplying exponentially.
Even if she were to break through from level-4 to level-5, she might not even be able to do it in a month, much less level-8.
This was because the difficulty of breaking through from level-4 to level-5 was even greater than the difficulty of breaking through from level-0 to level-4.
