The plot of Kakashi, Detu and Lin?

The three of them are comrades-in-arms, just like Naruto, Sasuke and Woody Sakura. Kakashi, Detu and Lin are the fourth generation students.

During the war, four generations led his three to carry out their tasks. Kakashi had just been promoted to forbearance at that time. According to the truth, when friends are promoted to forbearance, they all give gifts. Four generations gave Kakashi a particularly bitter pill, and Lin gave him a simple small medicine box and gave him nothing. In the battle, Lin was captured by the enemy and lived under one roof for four generations. She wanted to take the soil to Lin, but Kakashi insisted on carrying out the task, so she took the soil to Lin, but he was no match for the enemy. At this time, Kakashi appeared magically and saved the soil. Her left eye was scratched by the enemy. When fighting the enemy again, in order to save Kakashi and the forest with soil, she was hit by a stone, leaving only one left eye. So Dai Tu asked Lin to transplant his left eye to Kakashi's eye as a gift ~ ~ Then four generations arrived and saved Kakashi and Lin, but Dai Tu died there. From then on, Konoha harvested a hero-Uchiha Obito, and Kakashi became the owner of Shalingen. The reason why Kakashi is often late is that he always goes to the Ling Wei Monument to mourn Detu before performing his duties.
