Itachi Uchiha began to write the information about 'Xiao', wrote down everything he knew, and then handed it over to Sasuke, while Sasuke was cleaning his backpack on the side. He had a lot of things, whether it was Ninja Tool or a lot of wealth.
After receiving some of Itachi's information, Sasuke sealed it so that it would not be easily lost. At the same time, if it was opened in the wrong way, it would be destroyed directly. This was enough to ensure that the secret would not be leaked. Then Sasuke handed the prepared things to Itachi.
"What's in here?" Itachi asked. "Inside is Chakra Metal. Get yourself a weapon. Go to Land of Iron to find Tenbu Shinzo. He is Forging Master who has just been promoted. Uchiha Clan will unconditionally build a special weapon for me. This one was made by him, and it is very easy to use. Even if you are not used to it, there is no harm in making one. In addition, there are many Sealing Scroll inside, including blank storage scrolls and scrolls with sealed ninjutsu. It is simple and convenient to use. When in danger, you can throw it out to block the enemy and buy yourself time."
"You can keep it for use. There is basically no danger here." Itachi thought it would be better to leave it to his younger brother.
"Now your Sharingan can't be used indiscriminately, or let people know our secrets, otherwise it will be very troublesome, so you should keep it, just in case. I have a lot more here. I discovered the secret place left by Land of Whirlpools, and all the wealth in it belongs to me."
"You are so lucky!"
"It's not good, it's not bad either. What needs to be done has been done. Now let's have a fight. I need actual combat to improve my strength, but it's hard to find an ordinary opponent. Deidara's ninjutsu is so restrained by me that I'm really not a good opponent." Sasuke was excited to start fighting Itachi. This was a good opportunity. How powerful was Itachi who started practicing again?
"Yes, but how can you have Water Release's Chakra? Fire and water exist in one body at the same time. Only Kekkei Genkai's ninja can do this." Itachi Uchiha's question Sasuke has no way to answer, after all, this is his biggest secret. Chakra is a mixture of mental energy and physical energy, so both mental energy and physical energy can determine the nature of Chakra, and his soul is a latecomer. After joining, Water Release and Chakra appeared. However, he was also curious about why there was no conflict between water and fire. What was there in his body that allowed the two to live in peace with each other.
"Who knows? This is not something I can decide, but I have three types of Chakra, but why can't I synthesize other escape techniques?" Although Sasuke knows that forming new ninjutsu requires special substances in the body, but it is not very clear in the anime.
"This is normal. Two kinds of Chakra are mixed to form a new escape technique, which is called Kekkei Genkai. People who possess Kekkei Genkai have a special substance in their bodies, which is like an aphrodisiac. Like chemical agents, two different properties of Chakra are allowed to react, and then new Chakra is formed. Do you know why there are less and less Kekkei Genkai of Shinobi World?"
"Is it because of wars and massacres? Many bloodstained families are often wiped out by the whole family. After all, Kekkei Genkai is too powerful, is that right?"
"Indeed, most people only have one Chakra attribute, but there are still many ninjas who have more than two Chakra attributes, but they cannot combine the two because there is something missing in the blood, and the formation of Kekkei Genkai has a certain degree of chance. When ninjas first appeared, there was no Kekkei Genkai, but with the constant chaos, various situations will occur., such as poisoning, phagocytosis or cell transplantation, unpredictable changes occurred in the body, and then Kekkei Genkai began to appear, and the person who had the mutation married a wife and had children, and his special bloodline was continued, so that The Kekkei Genkai family was formed. As things like this continue to happen, there are more and more Kekkei Genkai families, but there are actually only three types of Kekkei Genkai, did you know?"
"You mean the three major pupil techniques, right?" Sasuke finally understood that Kekkei Genkai is not born. Except for the three major pupil techniques, the others are just acquired due to special reasons. Now that ninjas have gradually formed a system of ninjutsu, the chance of Kekkei Genkai appearing is constantly shrinking.
"Yes, do you think the three major pupil skills can be formed by what combination of Chakra attributes? This is Kekkei Genkai that is truly inherited from genes and cells, but is not formed by blood mutation. Those Kekkei Genkai who have acquired achievements have many problems. They often People often get blood diseases, which are completely incurable. This is one of the reasons why Uchiha Clan is proud of Sharingan. "When Sasuke heard "blood diseases", he thought of Kimimaro. Isn't that how he died? It seems that it is a good thing that there are no so-called Kekkei Genkai escape techniques.
The understanding of Sasuke has been improved. To put it bluntly, except for the three major pupil techniques, Kekkei Genkai is formed through chemical reactions inside the body. Since it is a chemical reaction, it must be poisonous. However, the chance of being poisonous is generally not very high, but there is always this danger, and it may break out at some point. The ninjutsu combination that Sasuke wants to develop can be said to be the application of physical phenomena. It is very safe. The most you can do is to blow yourself up with something like a bomb, but this can be controlled. As long as you control the amount of use of Chakra, there is no danger, and safety can be guaranteed. At the same time, the power cannot be said to be worse than Kekkei Genkai. Isn't it a confrontation between chemistry and physics? Interesting!
Sasuke was in high spirits again, but now it was better to fight Itachi first. His blood had begun to boil, and he would not let go of this rare opportunity for actual combat. "I understand, it seems that it is not bad without those Kekkei Genkai, so let's have a good fight. I have been practicing for a long time and still don't know what my strength is. As long as I don't use Sharingan, everything will be fine. Use it, come on!" Saying that, Sasuke lifted Sealing Jutsu, and walked out of the wooden house first, and came to the training place used by Itachi. The place has been made very spacious by Itachi, but the traces of various ninjutsu are very obvious.
Itachi followed Sasuke out and stood opposite him, "The foundation of ninja is Chakra, then ninjutsu, Taijutsu and Genjutsu, Genjutsu is for the Uchiha Clan is basically useless, so let's start with Taijutsu and let me see how far you have grown." Two very similar-looking people stood opposite each other with Sunglasses. Only the clothes on their bodies were different, otherwise it would be difficult to tell them apart.
