It tells us the truth that Uchiha Itachi has been hiding the fact that he killed Neiguang and his parents. Because he felt that he couldn't tell his brother the truth and made his favorite brother hate him. At the last moment, he didn't forget to help his brother so that he could live a better life. I passed on my abilities to Sasuke.

Uchihiro genocide night:
Although the inner clan was entrusted with an important task by Konoha, the whole clan was farther and farther away from the core of power. Tribal leader Uchiha Fugaku plans to launch a coup to usurp Huo Ying's position. Uchiha Shisui wanted to stop the rebellion with other gods, but Tuanzang didn't trust him and took Shuishui's right eye instead.
In order to prevent the last left eye from falling into the group, Shuishui gave the left eye to the ferret, so that the ferret could use it to protect the village. After that, Shuishui pretended to throw his left eye into the South River and committed suicide. Uchiha Fugaku ordered Uchiha Itachi, the captain of the dark department, to go deep into the top of Konoha Mountain and spy on the secret.
Skunks can't bear the ninjas in the village to kill each other, and reveal the coup plan of Neibo to the top of Konoha. Three generations of Huo Ying Sarutobi Hiruzen hoped to reach a settlement with Neiguang through negotiations, while Shimura Danzou, then the head of the Dark Department, prepared to annihilate Neiguang's clan in one fell swoop, and the group threatened Sasuke. Finally, the skunk decided to cooperate with the masked man (actually Uchiha Obito) to annihilate the whole clan, but asked Tuanzang to let Sasuke go.
After the genocide, the skunk joined the Xiao organization as a spy, continued to spy for Konoha and secretly guarded Konoha. In the process of genocide, Shimura Danzou and Uchiha Obito collected a large number of saringam respectively. This also paved the way for the later use of Nagi, who lived in Tibet and took soil with him.
