How did Obito Uchiha die?

Kakashi, Obito, and Lin are all subordinates of Namikaze Minato. As the son of Konoha White Fang, Kakashi is a genius ninja, while Uchiha Obito, a member of the Uchiha clan who is supposed to be a genius, is the weakest member of the family. The relationship between Obito and Kakashi was like the relationship between Naruto and Sasuke. If Naruto is compared to Uchiha Obito, then Kakashi is a genius ninja like Sasuke. I remember that during the third game of the Chuunin Exams, both Kakashi and Sasuke came late. Kakashi said, "Sasuke is just like me!" That day was the day when Kakashi became a Jonin, and it was also the day when he performed his first mission as a captain. Due to the shortage of talents in Konoha Village, Minato-sensei and Kakashi, who are both Jonin, have to perform separate missions, while Obito and Lin are assigned as Kakashi's subordinates. In order to celebrate Kakashi's promotion to Jonin, both Minato-sensei and Lin gave Kakashi gifts, but Obito did not. Kakashi reached out for him, but he couldn't take it out. On the way to perform the mission, Kakashi defeated a large number of enemies with his own Chidori move. However, facing the incoming enemies, Obito was so frightened that he cried. But as the captain, Kakashi's insistence on going his own way, ignoring his companions, and just blindly abiding by ninja rules made Obito very dissatisfied. Afterwards, from Teacher Minato, Obito learned that the father of Kakashi, known as Konoha White Fang, was once the pride of Konoha, but during a mission, his father gave up the mission in order to save his companions, and the result was that the village It caused huge losses. His father was reviled by the villagers, and his rescued companions also slandered him. He finally chose to kill himself. From then on, Kakashi believed that ninjas do not need emotions, and only performing tasks is what ninjas have to do. After Minato-sensei and Kakashi separated, Kakashi's group was attacked by the enemy. Medical ninja Lin was taken away by the enemy. Obito was anxious to save her. As the captain, Kakashi still thought it was necessary to perform the mission. The first place is actually equivalent to abandoning Lin. The angry Obito punched Kakashi hard and said something that would affect Kakashi's life: "I think White Fang is a real hero. Indeed, in the world of ninjas, those who break the rules will be treated as Trash, but those who don’t value their companions are trash among trashes.” Just when Obito arrived at the hiding place of the Iwa Ninja, he was discovered and attacked by the Iwa Ninja. Fortunately, Kakashi was discovered by his conscience and rushed to relieve him in time! crisis. Iwa Ninja Oishi used the camouflage invisibility technique to hide himself again. Kakashi was attacked while protecting Obito and lost his left eye, leaving a deep knife mark on his left face. However, because of his desire to protect his companions, Obito Uchiha inspired the hidden power of Sharingan to see through the enemy's invisibility and defeat Oishi. The two then teamed up to rescue Lin. But at this time, the Iwa Ninja Huoguo used the Earth Escape Technique - Rock House Collapse, causing the rocks on the cave to collapse and press on Kakashi and the others. But because Kakashi was blind in his left eye, he couldn't see the gravel falling from the left, so he was hit and fell to the ground. When Obito saw it, he rushed back to rescue Kakashi, but instead he was crushed under the boulder, his right half of his body was shattered, and his life was in danger. Before he died, he transferred the Sharingan left on the intact half of his body to Rin and transferred it to Kakashi as a gift for Kakashi's promotion to Jonin. He was then crushed to death by falling rocks. In order to commemorate his lifelong friend, Kakashi would go to the monument to worship every day, which was why he was late every day.
