Kakashi retires and Kai travels in episode 106?.

The 106th episode of the Japanese anime Naruto "Boruto" has been aired, titled "Yu Yan Ninja's Tie, S-level mission".

Plot introduction:

It turns out that Sarutobi will perform a mission in the future. Before going on the mission, he worshiped his father Asuma. After Yuhi Kurenai asked Sarutobi to be careful when going out in the future, Sarutobi Tobi Mirai went out, and Yuhi Kurenai, who was once young and beautiful, was already old, and her face was actually full of vicissitudes of life, which showed that it was not easy for one person to bring up Sarutobi Mirai.

Sarutobi Mirai was walking in Konoha Village and bowed to the stone statues of the seven Hokages. At this time, Nara Shikamaru, Uzumaki Boruto and Nara Shikadai met Sarutobi Mirai. Shikamaru took Boruto Uzumaki and Nara Shikadai to eat burgers. They chatted briefly for a while. Suddenly, the style of the painting changed. Nara Shikamaru asked Sarutobi Mirai to guess a puzzle. This was a tribute to "Detective Conan" I often guess the answer.

Sarutobi Mirai told Uzumaki Boruto that he was going to perform an S-class mission. Uzumaki Boruto was initially surprised, but when he learned that it was just a mission to escort Hatake Kakashi and Metkai, Uzumaki Boruto Boruto's curiosity was gone. Sarutobi Mirai left Konoha Village after meeting up with Hatake Kakashi and Metkai.
