The strength of the second generation far exceeds that of the third generation. Why are the three generations called the strongest fire shadow by later generations?

Sarutobi Hiruzen, the third generation of Huo Ying, had the longest reign, accounting for more than half of Konoha. In terms of internal affairs, Huo Ying's three generations are very modest, have the demeanor of elders and are good at propaganda. They formulated the "will of fire" for Konoha Ninja Village, which transcends the family interests and the interests of Konoha are supreme, and also made a classic interpretation of it in poetic language. "Where the leaves fly away, the fire will inevitably illuminate the leaves in the village and sprout again" (its excellent propaganda ability was later inherited by Jiraiya and Naruto, which had a far-reaching impact on the world). This, supplemented by the tough measures of gathering and hiding, bite the hand that feeds you, makes the family consciousness of Konoha Village gradually decline, and Konoha, a ninja who transcends the family, becomes more and more stable.

In terms of diplomacy, three generations of Huo Ying participated in and led two of the four world wars so far, and both won Konoha's victory, thus establishing Konoha's dominant position among the five major countries and ushered in the most prosperous period in history, so its outstanding leadership ability is beyond doubt. The individual battles of Huo Ying's three generations are much stronger than generally believed. Being able to master thousands of endurance, he is known as the "professor" of endurance. The most important thing is that he can launch five kinds of endurance (only a few people in the ninja world can do it, such as Jiaodu, because it has five hearts), which also shows the powerful endurance development ability of Huo Ying's three generations (this ability was inherited by orochimaru and also had a far-reaching impact on the world). Therefore, his achievements in Ninjutsu can show that three generations of Huo Ying are not ordinary geniuses.

In addition to leading Konoha to win all previous wars, three generations of Huo Ying also established a super-strong world structure in the world (at least to the fourth generation of Huo Ying). In addition, its greatest contribution is to make the Konoha family politics completely history without the outbreak of turmoil during decades of governance. In this process, three generations of Huo Ying all showed patience as a teacher. Gan doesn't mean to suppress the big clan, but to support the development of ninjas without background. Although he is in Huo Ying's position, he personally teaches people patience. Among the three forbearance, except Gang Shou, who is the granddaughter of his teacher, the other two have no family background, and the Qianshou family lost its former position during its three generations in Huo Ying (the specific reason is unknown). Although he was born in an ape-flying family, the ape-flying family was not distinguished by Huo Ying's three generations. The last three generations of Huo Ying also dared to make a decisive decision when dealing with this big family. After three generations of Huo Ying acceded to the throne, Uchiha Kagami and Akimichi Torifu, two cronies of the second generation Huo Ying, were decisively excluded from the upper level, and only three people without family background were recruited as Huo Ying consultants. With their continuous efforts, Huo Ying, the first with no family background in Konoha history, and Huo Ying Namikaze Minato, the fourth generation, came to power, which marked that Konoha got rid of the shackles of the family.

So he is called the strongest fire shadow. Not only in strength, but also in the above content.
