"Do you want me to find out what it is?" Bora asked with an excited expression and suddenly he squeaked and fell on the floor as if someone had pushed him down.
Ugghhh
The big bat looked down at him and said "I knew you would think something like that which is why I called you here to warn you. Yami has proven himself to be worthy so don't do anything behind his back. Teach him the stealth technique that he wants and prepare him for Sage mode. I am planning on going to meet that old Toad Sage. I have a few things I need to ask him."
Bora quickly got up and nodded his head and asked "Are you sure you want him to learn Sage mode? We can't back out then."
"Yes I have taken this decision before Yami's body even completed reconstruction. Since he had just a close win with the monster I knew that the first thing he would demand is Sage mode training. Luckily the kid is smart enough not to hurry things." The big bat said.
"Okay, I will prepare him for it. But still, it will take 6 months for that to happen. I won't start teaching him sage mode until he has learned the skills I teach him to mastery." Bora said and left the cave in the direction where Yami was.
As he reached the cave, he saw Yami had just come back from taking a bath. "The paleness your body had has lessened quite a bit."
"Yes...it appeared when I signed the contract but I wonder what happened for it to lessen now." Yami asked to which Bora said "At first, it paled because your body wasn't used to it but now your body is specifically made for it so this is the healthiest situation. Firstly come here and sit. I want you to focus on only your heart and tell me what do you think is different in you?"
"Don't tell me I have two hearts now.." Yami chuckled as he sat on the rock in front of Bora. He closed his eyes and continued breathing for a few seconds. He didn't even actively circulate his chakra and suddenly opened his eyes and said "How is this possible?"
Bora smirked and asked "So what did you notice?"
"My heart... it's only beating once every 10 seconds and that too the rhythm isn't changing." Yami said as he put one hand on his chest.
Bora nodded and said "Yes...remember when I told you that summons don't need to actively move chakra and it is imbued in blood? Now your chakra is also imbued in your blood so only pumping it once every 10 seconds is more than enough. This increases your physical capabilities to a great extent and also bathes every cell of your body with chakra."
"Can it be changed?" Yami asked...one of his best genjutsus were performed by changing the heart rate of his victims to a particular rhythm which would change the victim's mood.
"No it can't...because it will only accept your chakra." Bora said.
'So like every other jutsu and genjutsu, even this technique has a weakness. It's good that I never tried to use the technique on any summoning animal.' Yami thought.
"For now do your regular training for a few days and get adjusted to the body. After that I will teach you the stealth technique" Bora said and handed Yami a few supplies like a simple sword, a few weights for training, and a black piece of cloth.
"What is this cloth for?" Yami asked to which Bora said "To stop you from using your eyes. The only way to increase your sense of one organ is to deprive the sense of another one. Don't worry about it now and do your regular training."
Yami nodded and started exercising his body as he usually used to do in the village. He did feel pretty strange at the start because the new body was way more strong and more rigid as compared to his previous one. The sudden increase in height also took a while to get used to.
4 Days Later__________________
Bora was hanging upside down from a branch of a tree looking at Yami training every day. Every morning he would just fly to the tree and hang from it. He wouldn't look or even say anything to Yami and Yami was also busy getting used to his new body. The new sword wasn't too sturdy for him and felt like a cheap one. The ones that are kept at the village academy for fighting or the civilian villages keep for protection against small-time bandits.
On the fourth day, Yami looked up at Bora and asked "Can I have a better sword? I am sure this sword will break if I even put chakra into it. It already starts to vibrate when chakra even comes close to it.
Bora who had used his wings to cover his face, stretched one hand exposing half of his sleepy face, and asked "Why do you need a sword right now?"
"What do you mean? I am a kenjutsu user. How will I kill without a sword? Using taijutsu or ninjutsu among multiple people is just a waste of chakra." Yami answered as he picked up a nearby cloth and started wiping the sweat on his face and neck.
Bora shook his head and said "The sword isn't the weapon...you are. You don't need your sword to cut your enemies...You need intent."
Yami was confused at Bora's words. He knew that it depends on the user how he utilizes his sword but the rest was Bora said felt confusing.
Before he could ask Bora again, Bora said "I take it that you have gotten used to this body of yours. Now let's start with training you in stealth techniques."
Bora then flew down from the tree...but just as he was about to reach the ground...he disappeared. As soon as Yami saw this, he thought that Bora had used some kind of jutsu that boosts his speed so as an obvious move, Yami looked back but there was no one.
He looked in the other directions as well and before he could think more he heard a voice in his head. "What are you searching for?"
Yami's eyes widened as he suddenly heard the sound. He had almost thought that Bora had use telepathy to connect with him but he realized that the sound came from the top of his head.
Yami sighed deeply and looked up to see Bora standing on Yami's head. "You are having too much fun doing this aren't you?" Yami then noticed that Bora had a wooden stick in his hand the length of Yami's arm.
Bora chuckled and said "I am going to have way more than this and to do that you will wear that blindfold I brought for you with the training supplies." Bora waved the stick with his one hand.
Bora had already told him days ago that the blindfold was to deprive Yami of his visual sense. Bora jumped down on the blindfolded Yami's shoulder and said "Now I will change my position every 7 seconds and you have 5 seconds to guess where I am or else I am going to smack you with the stick. And yes you can't use your enhanced senses of smell and hear as well. Use the usual senses that you got as a human."
"What the heck? How am I supposed to know where you a...Owww" Yami was arguing when he was hit on the head with a stick.
"In the hidden leaf's academy and their shinobi standards, you must be a pretty talented individual to learn everything but not for me so don't think that you will breeze through this." Bora said and this time the voice came from a different direction.
Yami tried his best to guess the direction based on the voice but he got it wrong every time. Bora didn't let the chance slip and smacked his head with the stick each and every time.
"Ughh...how am I going to do that without using enhanced senses?" Yami asked in an irritated tone. Bora quickly hit him with the stick and said "Never let your face and your actions act like a window to your mind and your heart. You were pretty calm and calculated when you first came here and now when one thing goes unexpected, you lose your composure?"
Yami breathed a few times and said "Fine...I will stay calm but at least give me a hint as to how I am supposed to achieve this?"
"The enhanced senses aren't the only thing that you got after signing our summoning contract." Bora hinted.
"Oh, you mean...."
