Renji was quite satisfied with my attitude towards training. Sun was yet to rise and I had just climbed up the cliff and was hanging on the edge. I somehow went through the first year of training. It did not took me a lot of time to master leaf concentration exercise and I got the basics of one sword Iaido down perfectly.... I assumed.
"Okay, seems like you have gone used to climbing the cliff. Now do it using only one hand." he said calmly with a straight face to me.
Sun was rising behind me and I am sure someone was playing koto in the background providing dramatic confrontation music. I looked Renji in the eyes and said-
"Bring it. I know you want me dead"
The bastard also looked at me. He gave me a grin and pushed me out.
*aaaaaaaaaaaaaaaaaaa* apparently this will improve my strength and discipline.
When I mastered leaf concentration exercise he moved me to an advanced chakra control exercise, tree climbing. He demonstrated me the technique to me though I have seen it used by Kodon clan. He walked on top of the tree like he is walking on plane ground. I also followed behind him but as soon as I tried to take the second step, the trunk of the tree cracked due to chakra and lit up due to small sparks I produced. I was burned and Renji could not contain his laughter and was rolling on floor.
I was frustrated," I can I not produce even a spark in around the sword even after all this training but anything else gets electrocuted."
"Your affinity for lightning is strong also if you will concentration so much chakra on one point and not pay attention what will happen?" I did not want to know.
"Disasters"
"Yeah no shit Sherlo-" (Author: stop no wall breaking)
"...."
This training took relatively more time, since it is more difficult. Rest of my daily schedule was same.
Nothing special happened except there was one major news. Kodon clan and kumanoi clan declared temporary truce and formed and alliance against The land of water. This news was shocking for Commander Yamato and Renji.

"Commander weren't kumanoi clan supporting The land of water's ninja?"
"Yes! Something must have happened and Rheo knows about it....keep an eye on him."

One afternoon after I did my one hand cliff climbing training, Renji-
"Rheo, I going to teach you enclosing technique and unsealing technique."
"....."I was broken from the training.
"Rheo, show some excitement. Using enclosing technique, a wide variety of objects and even living things can be stored within Scrolls, and can be released when the scroll is opened or meets a specific condition. It is possible to seal even Ninjutsu into a scroll. Unsealing technique as the name implies releases the object in a scroll."
This got my attention quickly. Suddenly all my fatigue vanished and I bombarded him with questions.
"How many and how large objects can be stored."
"Depends on chakra used and formula used on paper."
"Can I unseal selective items enclosed inside."
"No, if you release such scroll everything inside will be summoned." This was a bummer.
"Can I have more than one enclosing formula on a scroll."
"I understand what you mean to do." he said in a cheeky way and proceed," Yes you can if there is space but which one to unseal requires chakra control and precision."
"Do I have to be in contact to unseal and can I control it's releasing space."
"No and no. There can be many ways to unseal. You can set criteria for unseal. Unsealed object appears every closed to the scroll used. One can manipulate it but only to small extend.
"Last question can I only use a scroll."
"you can use any piece of paper until the formula can be written."
Renji was delighted to see my enthusiasm but had a troubling look when he saw my devilish grin.
Another year passed by like this and I was moved onto the water walking exercise. There was a lake which was used as my training group. The lake would remain frozen for nine months,i.e. during winter. Thus I only had 3 months to learn it. To speed up my learning speed Renji that bastard would pass electricity in the water using his sword. Cold freezing water was not enough so he even electrocuted me everytime I would sink.
In the third year of training under Renji, I was now able to infuse lightning chakra to my sword and all the training also improved my Body Flicker technique. I can continuous fight using body flicker for an extended period of time. I fought him Renji time to time to improve my Iaido. Every fight against him made me aware of a new error in my fighting style. He exploited every opening against me.
"Rheo I don't think anyone training in Samurai academy can beat you in Kenjutsu. You are only something over eight. In less than 10 years you might surpass me."he said to encourage me.
"This much will not affect my growth right."
"You asked that question too late. But do not worry."
Training under him improved my other Ninjutsu too. I can create upto 30 clones(author :normal ones not shadow clones) and my transformation are pitch perfect. During hunting I can stab even wolfs on there head when I transform into one of there kinds, even disguising my smells.
Though my chakra control was awesome I had a great deal of difficulty in samurai sabre techniques but I got it down somehow. It took me another one year to learn them. But now I can manifest different humongous chakra weapons like an axe whose blade is more broad then my own body and a broadsword. This helped in training of weapons I did not have access.
I can also use the technique-Flash, a swift ranged attack where the user swings their sword at a target after coating it in chakra, releasing a sharp crescent of chakra in the arc that the blade was swung. This was the same Technique which repelled Roen. He also thought me an advanced version called Rupture. The user violently swings their chakra enhanced sword with the intention of striking an approaching opponent, releasing a wave of chakra to cut a target.
"Rheo you are ready. Meet me tomorrow with full preparation and whatever you need for your Ninjutsu. I know you practice them. Tomorrow we have a fight".
