Sasuke's training is still going on. He wants to improve his strength before going to Land of Grass. He can't tell to what extent he will improve his strength. After all, there are disadvantages in practicing alone. There is no reference and no one to guide, but Sasuke has an advantage, or the advantage of a time traveler, that is, he can clearly know many things, especially how to use ninjutsu, and it is relatively easy to develop.
He has been studying, especially when he was in school. He read a lot of basic theory books just for today. At the same time, Chakra's control is also very proficient, so what is left is to study the hand seals of ninjutsu. The twelve kinds of hand seals have ever-changing combinations, but they cannot be used casually. Because you don't know what kind of effect those random combinations will have. It may be useless, or it may create a big bomb. These are all uncertainties, so the development of Sasuke needs to be careful. I don't know how Sasuke in the anime did it.
Sasuke encountered a lot of difficulties in the development of ninjutsu, especially the combination of Hand Seals. Twelve hand seals are indeed not many, but it is too difficult to combine them. This is not a problem of several powers, because the repeated use of hand seals makes this possibility infinite. Magnified, there can be dozens of hand seals with many ninjutsu, many of which are reused. In this case, if you want to develop new ninjutsu, you first need to have a sufficient understanding of the hand seals, but Sasuke has just ignored this problem. He has not studied this issue in depth. Any invention and creation must have a foundation, and the same is true for ninjutsu. Hand Seals's speed is good, and Chakra's control is no problem, but how come the specific research on hand seals is ignored?
Sasuke was in a dilemma regarding the current situation, but he had to keep going no matter how difficult it was. Otherwise, how could he develop ninjutsu? This situation was unacceptable to him, so Sasuke gritted his teeth and decided to start studying hand seals immediately. First of all, let's talk about the running trajectory of Chakra. Let the mental power and the energy in the cells gather in the Dantian, which should be the Dantian, and then form a cycle of head, feet, abdomen, chest, hands and then head. Sasuke knows the meridians through which the circulation passes, and then the single Hand Seals of the hand, left hand and right hand Hand Seals have different effects. They control the meridians on the left and right sides of the body respectively. Sasuke is not a student of traditional Chinese medicine, but when he studied Medical Ninjutsu, he knew the names of the meridians of the human body. Three Yin Meridians of the Hand, Lung Meridian of Hand-Taiyin, Pericardium Meridian of Hand-Jueyin, Heart Meridian of Hand-Shaoyin, Three Yang Meridians of the Hand, Large Intestine Meridian of Hand-Yangming, Sanjiao Meridian of Hand-Shaoyang, Small Intestine Meridian of Hand-Taiyang, Three Yin Meridians of the Foot, Spleen Meridian of Foot-Taiyin, Liver Meridian of Foot-Jueyin, Kidney Meridian of Foot-Shaoyin, Three Yang Meridians of the Foot, Stomach Meridian of Foot-Yangming, Gallbladder Meridian of Foot-Shaoyang, Bladder Meridian of Foot-Taiyang, this is the name of Twelve Primary Meridians. The mudras correspond to these twelve meridians, and the Hand Seals of the left and right hands are the flow of Chakra in these meridians. The combination of different mudras is an effect achieved by the continuous flow of Chakra in these meridians. The faster you Hand Seals, the faster the effect will occur.
Based on this principle, Sasuke studied it carefully again, and with his photographic memory, he studied very quickly and memorized all the different combinations. Only in this way can he be handy in the subsequent development. This workload is a bit heavy, but Sasuke has to study what the effect of the same handprint is, and what the situation of different hands is. He is not afraid of wasting time, and he is not afraid of wasting time, and he can remember these changes and differences in one go. This gives him new hope, and this kind of research also strengthens him Chakra's control ability and some small discoveries made him very surprised, because he has always warmed and nourished the meridians throughout his body, which made his meridians very tough and wide. The Chakra mobilized by a hand seal can be expanded, and the Chakra mobilized in more meridians can make the power of Ninjutsu can be enhanced or reduced, but the workload is much greater.
At the same time, Sasuke records all his observations and findings every day. He plans to make a Uchiha Sasuke's Ninja Handbook in the future and include everything he knows. This can be regarded as leaving a name in history, right? Everything in the outside world has nothing to do with Sasuke. He has now become a 'science madman', studying day and night. What he did made Danzo very depressed. He couldn't find any trace of Sasuke. Although he had limited manpower at his disposal now, it shouldn't be impossible to find him at all. He was the subject of suspicion regarding the incidents of Kumogakure and Kirigakure. Although Although there is no evidence, suspicion does not require evidence, so now he is being stared at, completely unable to move, and Third Hokage is completely ignoring the matter. Even if Danzo goes to Third Hokage, it is useless, and Third Hokage simply disappears behind closed doors.
Some of the members of 'Root' submitted their lists. These people are basically people that Danzo doesn't value. Tsunade started assigning tasks to them for various reasons. You don't have to go, but you will become a traitor in no time. It will be no problem to kill you directly. At the same time, a large number of Tsunade's old department was activated, as was Jiraiya's old department. You must know that the two of them and Orochimaru were once the commander of Konoha, and Orochimaru had die-hard loyalists, let alone the two of them. Many of the Jonins Kakashi and Might Guy have fought under the three of them. At the same time, the current Clan Head of some families has also worked under them before. Shikamaru's father Shikaku is one of the representative figures and directly became Tsunade's staff officer.
At the same time, Tsunade took advantage of the two attacks on Sasuke to directly take over the management rights of Land of Whirlpools and began to send people to take over. The place was very wealthy, and at the same time, for Konoha The ninjas of have no grudges. The civilians welcome Konoha to take over here. They just pay some taxes, but their safety is fully guaranteed. Konoha directly set up a base here. Daimyo and Ninja Village of Land of Whirlpools are gone. There is no obstacle to taking over here. Tsunade directly ordered the establishment of a base here, which just isolates Land of Fire and Land of Water, forming a maritime defense line. Moreover, the taxes here are directly attributed to Konoha, not Daimyo of Land of Fire. Konoha's income has increased a lot, which makes Tsunade's reputation unparalleled for a while, and it is impossible for Danzo to fight against it.
Uchiha Sasuke doesn't know the changes he brought to Konoha. He is still immersed in the long research and has the style of Orochimaru. Now Sasuke knows why Sasuke can do it in the anime. He quickly developed ninjutsu, because Orochimaru's years of research have been of great help to him, and with Yakushi Kabuto, an excellent medical ninja, it was hard not to think fast, but he didn't want to go there at all, it was too disgusting, yes, Sasuke was afraid of nausea.
