How did Toyotomi Hideyoshi achieve reunification without any background?

Toyotomi Hideyoshi can do all this, first of all, because of his persistent personality. For example, when he was down and out, he was just a small messenger. It can be said that sometimes he doesn't even have enough to eat and has no place to live. Later, he had to sell some gadgets to maintain his present life, but he was not knocked down by the immediate difficulties, and he still tried to find a way out and succeeded step by step with his persistent personality.

Secondly, he is lucky. Coincidentally, he found a job as a handyman, but this kind of handyman is not a handyman in the ordinary sense. He was working in the Matsushita family, and Toyotomi Hideyoshi always had a dream that he would become a samurai like Master Matsushita, and he himself was working hard towards this goal bit by bit. Although he was finally fired, he used this job as a handyman.

In addition, he also got the help of a noble person, that is, Oda Nobu. Toyotomi Hideyoshi used his previous working experience in Matsushita family, and with his excellent ability, he gradually got the promotion of Nobuyuki Oda, and made great contributions to Nobuyuki Oda in a subsequent battle, and Toyotomi Hideyoshi became the number one hero in that battle. Moreover, he also married Asano Nagaakira's daughter because of this credit, thus establishing his position.

Through his subsequent efforts, he gradually grew into Nobuyuki Oda's most trusted confidant, and then gradually realized the reunification of Japan.
