Namikaze Minato is not related by blood. Why can he be a "fire shadow"?
Naruto Village is a semi-militarized organization, and the selection criteria of leaders are naturally based on the strength of combat effectiveness.
Naruto Village is a militarized autonomous entity and has established cooperative relations with other countries. Its own strength directly determines how much resources it can allocate and whether it has enough voice in politics.
Therefore, for the shadow, the highest power symbol of each ninja village, the selection standard is first to look at the candidate's personal combat effectiveness. Basically, the characters who can become shadows are all ninjas with the highest fighting power in the same group, but the fighting power and lineage of Naruto are not directly related, which does not mean that the descendants of ninja family have strong fighting power, but have a strong connection with the role setting (their own talent).
If the Ninja Village chooses the successor of the shadow in a way similar to hereditary system according to the blood relationship, it may cause great losses to the interests of the Ninja Village or the country because of the lack of the highest fighting capacity, or it may not be able to maintain the smooth internal management of the Ninja Village because of its own lack of ability.
In this way, due to the requirements and oppression of the internal and external environment, it is necessary to abandon the hereditary selection method and adopt the ability evaluation to select the shadow heir. Namikaze Minato obviously meets this standard, so it can be the fourth generation of Huo Ying.
In terms of ability, Namikaze Minato mastered the space ninja skill Fei Raytheon, which is extremely difficult to learn in the plot and has a good actual combat effect. With a good amount of chakra and a powerful sealing technique learned from Jiu Xin Nai, Namikaze Minato is obviously up to standard in personal combat effectiveness. Judging from the results of selecting Huo Ying in past dynasties, it is not necessary to be related by blood to become Huo Ying.
Watergate incident can be the result of internal power struggle besides its own strength.
Watergate can become a fire shadow, besides its own ability, meritorious military service and personal values to meet the needs of management, there is also an influencing factor, that is, the problems of three generations of fire shadow, Tuan Zang and orochimaru. The concern for power struggle is reflected in Tuan Zang and Three Generations of Fire Shadow.
By rights, orochimaru is also a top ninja. However, his behavior does not conform to the values of Huo Ying's three generations. In addition, in order to compete for more resources to support and collude with Tuanzang, it is naturally impossible for interest groups dominated by three generations to hand over the subsequent ruling power of Muye Village to them, and they will choose Namikaze Minato, which is closer to themselves in terms of values and personal relationships. There is an interesting phenomenon in Huo Ying. Basically, there is a blood relationship or mentoring relationship in all previous generations.
As the saying goes, where there are people, there are rivers and lakes, and there will inevitably be power struggles and partisan disputes in the political system. However, Namikaze Minato naturally belongs to the Sarutobi Hiruzen school because of the plot setting, and is dominant in the choice of Huo Ying's candidates, and it is impossible to be completely fair and just in interpersonal relationships, which is biased. The choice of three generations of Huo Ying proved his point of view, and Namikaze Minato has good values in both combat effectiveness and management ability.

Finally, to sum up, in fact, the choice of Huo Ying is not based on blood relationship, but on the candidate's personal fighting capacity, values and factions. Namikaze Minato's ability to become Huo Ying naturally meets the standards in several aspects. Please forgive me if the analysis is not in place.
