The next skill, Mana absorption is a strange one.
I never heard of or seen anyone being able to absorb Mana or any kind of energy during battle.
To absorb Mana in the body and progress in ranks, one has to have a way to absorb them in the body.
You can't just sit down and try to absorb the Mana into your body randomly hoping that it will work just fine without leaving any hidden dangers in your body or maybe the Mana absorbed might cause some chaos by entering through the wrong meridians.
That's why people who don't have a good or a high-level breathing technique wouldn't be able to advance much in cultivation.
I thought that by gaining a system, I will be able to escape this problem as it will help me through level up like in novels and games.
But unfortunately, there was a notice written down in the class description saying that the advancement of my class will depend entirely on me and that the system won't give me any assistance.
