After I come back two weeks has passed and sword smith from swordsmith village come to deliver my sword.
"This is your sword, try pulling it out.You practice thunder breathing right?.I think your blade color should be yellow." Sword smith said.
"Nichirin sword will change color depending on the user" master explained.
"Oh,okay master" I also want to know what color is my sword.
So I pull out the blade and then the color of blade didn't change much but have purple lightning pattern motif down the length of the blade.
"Ho, Interesting I have never seen this change before what future you will hold? I will wait and see" Sword smith mumble to himself.
"Then my duties end here I will return first" sword smith get up and go back.
"Thank you for katana sword smith San" I bow and said thank you.
Then after I receive my katana.I also go train with my master to master Advance Total Concentration.
'Total Concentration: Constant'
"this is a technique that can maintain Total Concentration Breathing at all times during the morning, noon,night, and even while asleep" Master explained.
"There is an immense difference in strength, speed, and stamina between someone who can maintain Total Concentration Breathing at all times and someone who cannot.By doing it every minute of the day, one's physical fitness drastically improves" that is what my master said.
During training time I also go to perform various task that Kasugai Garasu said.
'But let's talk about training that I trained.Well with my physical that as strong as a normal demon so it's didn't that hard'
'The training process involves blowing into a special type of gourd, one that is much harder than usual. The objective is to blow into the gourd with enough strength to make the gourd break apart'
'As training progresses, the gourd is replaced by larger and larger versions of the same type of gourd. The largest known examples are about the size of a chair'
'To be able to improve Total Concentration Breathing and blow the gourd, I work on the lung power first'
'I also practices holding my breath. Lastly, I meditation helps with concentration and breathing slowly and deeply circulating the air all the way to the fingertips'
'My master also helped by when I stops doing Total Concentration Breathing during my sleep'
'After sometimes passed I finally master the Total Concentration: Constant'
'I perform and kill many demons maybe because my luck that I find many demons So I get promoted my ranked to kinoe rank'
And one day I received the mission to go help Kaigaku.
Well it's time to do thing that I want to do for a long time.
