Namikaze Minato is not considered to be the descendant of the ethnic group with bloodline advantage in Huo Ying, but his learning ability of Ninjutsu is abnormal.
There is little detail about Namikaze Minato's family in the plot. Personally, it should be a factor that the number of ethnic groups is scarce or the comprehensive strength is not strong. Perhaps the only thing that can be remembered by others should be Huo Ying's four generations. Personally, I think that the reason why Huo Ying's four generations are the first bloodless people of Huo Ying lies in their ability to learn against the sky.
In addition to the familiar Flying Raytheon, he can also improve his immortal mode during the period of being sealed by ghosts. You should know that Huo Ying's four generations didn't master the immortal mode very well (even reached the level of Jiraiya), but after being reincarnated by filth, in addition to the Kyubi no Youko mode, the four generations also practiced the immortal mode that they were not good at in the past, which was too strong.
In fact, without the support of my body, I can learn skills by my soul. This is the only one in Huo Ying. Of course, if it is Huo Ying's second generation in terms of skill richness, most of the forbidden arts in Muye Village are done by Huo Ying's second generation, including Huo Ying's four generations of flying Raytheon, all from Huo Ying's second generation.
Although the second generation of Huo Ying did not inherit his brother's powerful intercellular cells, he was still a member of the direct descendant group of Otsuka Muhuiye.
Judging whether a character has a blood disease in Huo Ying does not depend entirely on whether he has a special blood boundary. Senju Hashirama's Mu Dun belongs to the realm of blood circulation, but in fact only one person in a thousand-handed family can use this skill.
The most obvious example is that the Neiguang clan is a big family and belongs to the direct descendant group of Otsuka Muhuiya, but not everyone in the Neiguang clan can open sharingan or even the kaleidoscope sharingan.
Therefore, although Huo Ying's second generation can't escape from the wood, it also inherits many characteristics of the Thousand-Handed Clan, such as the huge chakra and strong chakra perception. These are the innate advantages of the members of a big family, but Namikaze Minato's innate advantage is not the special ability of the Thousand-Handed Clan to inherit the Ming-Ming Night except his strong learning ability.
Mu Huiye is good at spatial transfer, which should be related to Senju Tobirama's ability to develop the livestock Flying Raytheon. However, Namikaze Minato, like other strong people without bloodline advantage, has made great achievements mainly by his talent and his own efforts.
Senju Tobirama is a ninja with innate advantages, because some of him are descendants of Otsuka Muhuiye. However, Namikaze Minato is not a direct descendant of Otsuka Muhuiya, and his success depends entirely on his own talent and efforts.
Finally, to sum up, I personally think that Namikaze Minato should be the first bloodless person of Huo Ying, because he has a strong learning ability. It should be unprecedented to continue to improve his immortal model after death. Huo Ying's second generation belongs to a thousand-handed family, and its bloodline advantage is still obvious.
