A Fei Hui and Naruto's fucking vortex team seal can be seen from the fact that the chains issued by both of them are barbed. And this kind of sealing technique is specially used to deal with bijuu. So teddy boy has the blood of whirlpool clan in his body. A Fei can always be reborn every time he is seriously injured, such as against the fourth generation and Xiao Nan. This ability is very similar to Gang Shou's regenerative ability. Gang Shou's regeneration ability is inherited from Qianshou clan or her grandfather's ability to hide wood, and no one else has it. Look at the wrinkled face when Xiao Nan knocked off half the mask of Teddy boy and Teddy boy met Sasuke and took off half the mask, and you can infer that he and Tuanzang belong to the same age group, that is, it runs in the family's age group. So teddy boy's identity will be vividly portrayed. Yes, he is the son of the first generation Huo Ying and the first generation Kyubi no Youko Zhu Li. Of course, Gang Shou's father may not be him. When teddy boy and Sasuke talked about ending the valley war, he showed admiration for the first generation. As a copy of the first generation, it was never called punk. Nagato mentioned in Spotted Mouth is not the Nagato we know, but a punk. Look from the age, spot and Nagato can't have an intersection, and there is a man that Nagato knows is spot. So teddy boy used to be called Nagato. Ok, now let's go one step further: In the early generation, nine bijuu were assigned to various forbearing villages to balance their strength, and the Meitu people sealed Kyubi no Youko in their own bodies. Later, Mito became pregnant with Teddy boy. On the day of delivery, Kyubi no Youko suddenly broke out and ran out. Spot took the opportunity to control Kyubi no Youko with Saringen and launched an attack on Konoha, thus ending the valley war. Finally, Kyubi no Youko was sealed again, and Teddy boy was born. But the birth of punk brought this disaster. Everyone looked at the child with strange sunshine, just like Naruto in those days. At that time, the first generation was dead, just like Naruto after four generations. In loneliness and cold eyes, teddy boy didn't meet a decent partner, just like I loved Luo in the past. Although he is Huo Ying's son, no one wants to get close to him. Everyone is afraid of him. Then, under the guidance of Ban, A Fei gave up the world completely and thought it was a hopeless world, which was fully revealed in the dialogue with Naruto. Just like orochimaru for Sasuke's existence. Diandian opened her eyes before she died. He gave his eyes to punk, so his eyes are punk's. Once, I accidentally found a red-haired child in Yuyin Village and decided that he was a whirlpool clan, so I named him Nagato and those round eyes (Teddy boy may know Nagato's parents, Nagato's parents may have asked Teddy boy's name when he was born in Nagato, and Teddy boy may say: Just call him Nagato). So this can be interpreted as that Teddy boy said he made eyes at Nagato. In the Third Endurance World War, A Fei accidentally discovered sharingan with soil. Maybe punk couldn't control his eyes at that time, so he had to get acquainted with sharingan first. Sadly, he only found one (the strength at that time should not be very strong). But he found that this eye has the ability of time and space.
