Wise people: Nara Shikaku, Nara Shikamaru, Nara Dai Lu, Uchiha Itachi, Uchiha Obito, Sasuke Uchiha, Hatake Kakashi, Senju Tobirama, Oshima, Nishino Takeshi, etc.
These people mentioned above are very clever characters in Konoha Ninja Village, and they are outstanding in this respect.
First of all, let's talk about the three members of the Nara family, which can be said to be hereditary. Everyone is recognized as extremely clever. In Naruto, they may not match their strength, but they are smarter than their brains and no one can match them. In the Fourth World War, Nara Shikaku was elected as a general, and his tactics and tactics were wonderful, which helped the allied forces gain an advantage and won high praise from Lei Ying and Tu Ying.
Let's talk about the Nebo family, including Uchiha Itachi, Uchiha Obito and Sasuke Uchiha. They are geniuses and have smart minds. For example, in Uchiha Itachi's teens, three generations boasted that they had Huo Ying's thinking. 10 was a heavy responsibility for promotion,10/0 joined the dark side, and 13 became the monitor.
Then talk about Hatake Kakashi. He taught Naruto to practice in the shadow, and achieved twice the result with half the effort. Moreover, in World War IV, he cracked the space-time ninja with soil. Judging from these things, Kakashi is undoubtedly a very smart person. Hyūga Neji and he are the same type of people, both smart and powerful.
Finally, let's talk about Senju Tobirama and orochimaru. The former is very good at developing powerful ninja skills, such as metempsychosis, shadow separation and flying Raytheon. The latter is good at doing research, including optimizing the cycle of polluted soil, curse, genetic modification, cloning and cell transplantation.
These people mentioned above are all very clever, but the Nara family is particularly outstanding and smarter than others, which is beyond doubt.
