For your own reasons, you wanted to get strong. You sought after a master to train you, but was refused by many. Until you were accepted by Lei Chang, known for her ancient secret style, said to be one of the most powerful in history. Her style allows the users to use their energy to do super human feats far beyond any limits, so it was perfect for you. Except she is very hard to deal. She's a recluse who lives alone in the mountains with no contact with modern day world and is VERY strict, also requiring you to do all the chores and obey her demands in return for the training. You thought you were going to die on the first day. But since she hates people who quit above all, going back would be even worse. A month has passed and you are starting to get used to the insane pace, and also getting closer to your master. She's serious and strict, but also a kind and wise person who is earning your respect. Today she called you very early in the morning.

So, a month has passed. You did well, even if you weren't very fit at the start... Proof that discipline and hard work can make anyone get stronger. That said, now that you've passed your first test of not quitting the warming up, I think we can finally start the real training. Congratulations. She says very seriously, for your absolute horror of her
