"OK now it's time for the second idea, similar to the first idea this also uses the concept from water walking technique." Raijin decides after calming down.
First he extends his right arm forward in a punching pose and creates a fist while channeling chakra in it and manipulate it like during water walking technique and once he succeeded he gradually began to increase the chakra amount as soon as the chakra amount doubles the required level a burst of shockwave erupts from his fist with a boom sound, the ground in front of him cracked and even the wall which is 10 feet away from him shows a slight crack. "Oh, I had thought that this would amplify my striking power by about 50 % like previous test but my striking power directly increased exponentially." Remarked an astonished Raijin.
See according to the scroll the process of water walking is nearly same as tree climbing one except in water walking one has to compress their chakra at the soles of their feet which helps them create a stable surface on the unstable surface like water and then they stick on them. Raijin was interested in knowing what would happen if the chakra overloaded.
"So, when I compressed the chakra it was stable but when the amount increases it also increases the pressure and once it crosses the threshold it burst out like an explosion but as it did not have any heat or flammable objects it produced only shockwave. So theoretically it can be performed from all the striking places of the body like fists, elbows, knees, calves, feet hell it may be possible to perform it from fingers and head." analyzed Raijin.
"So in a nutshell I have two separate techniques which will help me increase my base speed and strength, it will be very difficult and time consuming for me to master both of them and use them simultaneously, its too much of a multitask especially during high intensity battle so I must combine then into one." Raijin decided.
First he channels chakra and completely covers his body with it using his experience from sticking stones from all over his body then he gradually increases the quantity up to the required amount for water walking and maintains this state for 1 minute and repeated this process to familiarize himself with the process, it took full five minutes to complete this process.
After repeating the process for dozens of times next he begins to compress all of the chakra and then increased the chakra amount to the just the threshold of bursting and maintains that amount, slightly more chakra and it will burst potentially injuring him so he was very careful. For the next five hours he again repeated the process from start to finish and once he gains basic familiarity, he decides to test it.
Raijin took a fighting pose 10 feet from a dummy on his backyard and took of in an instant he was in front of it struck it with a full power punch. The instant his fist struck the dummy the pressure from the strike increases the pressure of the already compressed chakra in that point and burst out with a shockwave and as a result the dummy and even the ground around it shattered. Even Raijin was affected but he stuck to the ground using chakra in the nick of a time.
Raijin shook his throbbing fist and exclaims baffled "What the hell is this, how can combining the two low level d rank techniques can create a technique which can do this much damage and if its this easy then why not every one does it."
After thinking for sometime Raijin shook his head "No no no, although the two are d rank control exercises my difficulty upgrade definitely made them like B rank at minimum and even I was able to master them in a month only because of my relentless grinding of leaf exercise from last years and when combine the two B rank techniques made them on par with at least A rank technique. Even this is not perfect version and simply impractical during high intensity battles.
First drawback is it takes about 10 minutes of prep time & its difficult to maintain for more than 1 minute at a time and after the time ends the that chakra disperses outwards and can't be used again. Second is chakra amount, although both the control techniques used only about half of D rank techniques but that's only when used on feet only.
When using them like the process chakra expenditure increase exponentially to about 20 time that means approximately equal to chakra used in 10 d rank techniques. Even if a regular chunin masters it at this stage he/she can only used this for about maximum of 4 time on their full chakra reserves. But Raijin due to having physical and mental energies in balance his chakra expenditure for every jutsu is halved can use this for about 8 times.
"I can only use this once I increase my mastery by practicing this technique as long as necessary for it to become ingrained in my instinct and seeing the difficulty level of it would require several months of relentless grinding." Sighed Raijin.
"Ahh, I wanted to take a C rank mission now that I have complete 10 D rank one but I must now postpone it. Although danger level in C rank mission is low it's not zero its best to have a reliable trump card before even facing the possibility of danger." reluctantly decides Raijin
"Ah even if I have decided to focus on this, I can't neglect other things. I must create a routine and follow it religiously till my first C rank mission. First, I must continue taking d rank missions like before which is 1 mission every three days. Then comes training morning is time for physical activity from 6 am to 9 am like body exercise, taijutsu and shuriken jutsu which will further stimulate my physical energy then 1 hour rest then from 100 am to 2 pm will be for this new technique practice this will also slowly increase my chakra tenketsu after lunch and a 2 hours rest then from 4 pm to 8 pm it will be time for practising fuinjutsu, genjutsu & medical jutsu as they all require intelligence they can further stimulate my mental energy." Raijin created a thorough routine.
"Oh! Nearly forgot to add a relaxation day, Ah I know every mission day will be relaxation day." Finished Raijin.
