after deciding to craft gravity seal first , ken went to the respective shops disguised as a normal adult and bought all the necessary ingredients and tools. ken was rich as he got the mission reward of an A rank mission with 4 million ryo of bounty with him so this little expenditure was a trivial matter for him .
ken then went to his apartment secretly after changing back and started practicing seals immediately. first he only created seals that had low difficulty and only used ink and paper for example chakra disturbing seal , simple storage seal etc . surprisingly Ken's mind worked like fluid while creating these seals because of his knowledge and this level of proficiency was seriously way more than his original expectations. so ken fortunately due to his perfect chakra control didnt fail a single time and now had 43 low level seals with him.
the basic language of programming is one of the most important aspects of a veteran programmer so for specialist of fuinjutsu it was pretty much the same . ken had the knowledge, proficiency and now the experience with it so his basics were rock solid. he was ready for advanced seals and coincidently the gravity seal was not the top grade seal . its difficulty could be considered in the upper advanced levels and the most challenging part was chakra control due to large number of runes . for this aspect ken was the best so the difficulty was almost non existent for him .
ken used shadow clone jutsu and made just one clone . his chakra was monstrous now so he didnt have to wait till it was full before starting the process. ken and his shadow clone wrote many symbols like small circles, kanji etc on the ground while one circle was written in the middle where he had to sit .
the symbols were all successfully written perfectly and ken poured chakra beast blood on small circles according to the proportion inside his knowledge. this only 23 minutes long process wasn't easy because every single ant sized kanji required too precise chakra control which was the reason this fuin was considered one of the most difficult seals .
ordinary seal masters would take hours or even days to completely craft all the symbols because of the precise chakra control required which was taxing on mind . but ken with the help of his shadow clone just needed 23 minutes as he has passive perfect chakra control which of course his clone had too .
his room's floor was completely shaped in a sun shaped diagram which had 7 small circles around it and tens of thousands of words in various lines . ken took a long breath and sat cross legged in the middle biggest circle . he bit his finger lightly and dropped little blood on ground . ken clapped both his hands and magical event happened .
the black and red diagrams lit up and the characters which numbered thousands came alive and started dancing in the air . ken closed his eyes and flared his chakra a little . again magically all the lines of characters were attracted to his figure and slowly wrapped his body . after 3 or so minutes Ken's body couldn't be seen properly as it was covered with black and red lines which were condensed with thousands of small characters. ken stopped his chakra flow and the lines that looked like snakes dissapeared suddenly leaving only an inch long G alphabet in kanji in the middle of his chest .
the symbol was glowing in shiny black light for a while before it dimmed and only the character remained etched on Ken's chest like a tattoo . ken smiled and stood up from ground as the process was successful. there was not even a drop of blood left on the ground so ken didnt need to clean anything either. ken decided to check the effects of the seal so he directed a very minuscule amount of chakra in the symbol .
suddenly ken dropped on the ground again on his knee because he wasn't ready for the sudden change in weight . ken of course didnt complain and just was overjoyed because the effects were even better than he had expected. a little chakra and the gravity rose to 10x normal which was way over the 5x estimate of ken . this was expected because Ken's chakra density had risen a lot after successfully assimilating the uzumaki bloodline with of course the capacity too .
ken decided to run some laps around the village after he set the gravity on 3x normal which was more easy than breathing to him as he had perfect chakra control. the chakra consumption even though every second was just too small for ken now so he constantly had activated the seal all the time.
now ken could run albeit a few times slower than normal in 3x gravity but this was only possible because of his body's adaptability which was another benefit of monstrous vitaly. now ken knew that he could become stronger daily just by activating his seal all the time even without exercising much .
ken got out of his house and jogged away . he passed the uchiha compound , inuzuka compound , akimichi compound, market etc without resting but stopped when he was a few meters away from the academy . ken was enraged to see some mobs that weren't even worth remembering to him bullying naruto who was bleeding from his head in a dark alley. this couldn't be considered even bullying anymore as clearly a mob child of the three assailants was holding a sharp mid size kunai in his hand which was probably the weapon that caused the wound .
- oye ! looks like you three are eager to die an early death ! you dare to bully my friend and even injure him with a kunai ? I'm sorry to your parents but even if they beg now , I wont spare you guys !
- wuu wuu .. I'm scared ! tch .. who is this clown ? do you guys know him ?
- ah! I remember him . he is ken who didnt come to class for a few months now!
* whisper whisper *
oh ? they dont know about my early graduation ? forget it ! I will ask iruka sensei about this matter personally sometime. now it's time to teach some brutal kids a brutal lesson hehe..
ken suddenly kicked the ground and instantly covered more than 4 feet in one step . he arrived in front of the mob kid who was holding the kunai and snatched it . just in the flow ken slashed the kunai at the mob's arm and of course blood and a scream followed . Ken's expression didnt change and he slashed in the same pattern at the rest of 2 mob assailants. the whole process from ken kicking the ground and finishing his assault didnt even take 2 seconds . this monstrous reflexes and speed even surprised ken himself because he didnt know that his body could move so much now despite him in constant pressure of 3x normal gravity. this was of course the benefits of uzumaki bloodline which had multiplied effects on him due to evolving after merging with the uchiha bloodline.
ken ignored the 3 screaming banshees and knocked out little naruto swiftly with a chop on his back before he completely opened his eyes . ken rudely carried the now unconcious naruto on his shoulder and immediately dashed towards the konoha hospital just in case to not leave any risks of infection from the head wound. as for the 3 mob children now ? who cares about them and ken practically ended their dream of ninja there . ken had precisely ruined some important nerves in their arms completely so they wont be able to use their arms much even after their wounds heal. simply because they wont know about the seriousness of their injuries until much later in future and then it would be too late . as for Ken's punishment ? hehe . . the protection and money tree called old fox hokage will have everything covered for him ..
