At the same time that the Uesugi family won successive battles in Hokuriku Province and Tohoku Ou, Ota Shimasa was not far behind, and wanted to quickly defeat the Takeda army and recover the country of Sagami. Koyama Asaki secretly offered Ota Zimasa a plan to encircle Wei and save Zhao - once again send troops to attack the hinterland of the Takeda family, Kofu, and force Takeda Shingen to collect his troops and return to Kai, so that the Uesugi army could easily pacify each other.

However, Ota Shimasa thought that this plan was quite risky, and that the slightest mistake in sending a partial division would wipe out the entire army, so he did not adopt the strategy proposed by Oyama Asakyuki.

However, what Ota did not expect the most was that Koyama Asakyuki would directly send his confidant Takanashi Naki to Aizu Wakamatsu Castle to ask for the opinion of the court. After listening to Takanashi's account, he agreed without much thought, and granted Koyama Asakyuki the right to command the state soldiers stationed on the Musashi border.

Koyama Asayuki, who received the approval of the court, no longer paid attention to Ota Shimasa, Yamamoto Temple Dingchang and others, and led most of the Oyama people to join the Shangshu soldiers alone, leaving only Mori Gozaemon, Mizuko Morinao, Funashi Goheiji and other retainers to lead more than 100 troops to continue to obey Ota Shimasa's dispatch.

Ota Shimasa could only stomp his feet angrily when he learned that Koyama Asayaki didn't tell him, after all, Koyama Asayaki was a member of the Asada's true sense, and he was still the one who married Asada's niece, so he couldn't do anything to Koyama Asayaki. And Ota Shimasa himself is just a genealogy retainer of the Uesugi family, and he was just awarded a class by the court.

Koyama Asakuki then integrated the Shangshu soldiers and the Koyama people, totaling more than 10,000 troops, from Musashi Chichibu Mountain, crossed Mt. Tenmu and entered Kai Province.

At the same time, Asadatsu quickly dispatched Kato Danzo to Ueno, and ordered Uesugi Keimitsu, Honjo Shienaga, Ogasawara Nagatoki, Momoi Yoshitaka, Soga Yushige, and Numata Yumitsu to quickly lead their troops into Kita-Shinano to contain Kita-Shinano's Takeda army, so that it could not send troops south to support Kai.

As soon as Honjo received the order from the court to send troops, he immediately set out to recruit troops, he had been refrigerated by the court for a long time, and he had to take this opportunity to make a great contribution so that his status was not lower than that of Koyama Asakyuki, after all, his main room was the daughter of Uesugi Keishinobu, and he could also get close to Kenshin.

In the third year of Yonglu, April 15. Uesugi Keemitsu was the general general, Honjo Shiranaga was the vanguard, Numata Yumitsu was the military advisor, Ogasawara was the deputy general, Momoi Yoshitaka was the commander of the Kohe, and Soga Yushige was the soldier ration, and a total of more than 10,000 troops entered Kita-Shinano-Saku County through Karuizawa. Subsequently, Uesugi Keimitsu set up a camp in Uenohara and surrounded the Takeda family's important town in Kita-Shinano.

As the vanguard of the invasion of Kita-Shinano, Honjo Shigenaga was ordered by generals such as Uesugi Keimitsu and Ogasawara Nagasagawa to attack the branch castle soldiers around the west and south of Komori Castle.

After receiving the order, Honjo did not resist, because it was a golden opportunity for him to make a name for himself and the two countries, and on the other hand, he could make a lot of military achievements after attacking the branch cities around Komojo Castle.

Subsequently, Honjo quickly led more than 3,000 troops from his headquarters to Iwao Castle. However, Takeda Shingen quickly ordered Hoshina Masatoshi to lead more than 3,000 troops, mainly the Suwa Ancestors, to rush into Saku County to support Komoro Castle, Iwao Castle, Uchiyama Castle and other important towns.

Tens of thousands of Uesugi troops rushed into Kita-Shinano like a whirlwind, and the momentum along the way was like a bamboo, and the Takeda family was caught off guard, they didn't expect the Asada's movements to be so fast. The retainers of the Takeda family stationed in the important towns of Kita-Shinano saw that the Uesugi army was attacking Kita-Shinano on a large scale, and they were immediately frightened and sent messengers to Kofu and Sunfu for help. News of requests for help from all over the country drifted like snowflakes into Sunfu and Kofu.

After Kita-Shinano was invaded by Kenshin and Nagano Yoshimasa several times, the people of Kita-Shinano were defeated and won less, and suffered heavy losses, so the important ministers of the Takeda family, such as Baba Nobubo, Mokaku Torada, and Hara Masain, successively wrote to Takeda Shingen, focusing on explaining to him the situation that "many soldiers died and the people were sad". Many of the Koshin clangin lords had secretly complained about Takeda Shingen's rule and policies, especially the Kokushino clansmen who had secretly presented Taidao and good horses to Kenshin.

At the same time, the Ueno generals stationed in Okushinano, such as Uesugi Keimitsu, Honjo Shienaga, and Ogasawara Nagasawara Nagaso, immediately joined forces with Iwai Mitsunaga, Iwai Narino (son-in-law Takanashi Yorimasa, Iwai Mitsuna's brother), Takanashi Hidemasa, Takanashi Yorikin, and Deura Kunikiyo and other Hoknobu servants to lead an army of 3,000 to the south in response.

Since the Uesugi army attacked the Takeda Domain in the north and south at the same time, the North Shinano Takeda Army lost the other. Although the Takeda Commander of Kita-Shinano defended the important towns of Katsumi Castle, Toishi Castle, and Makinoshima Castle under the strict defense of Sanada Yukitaka, Tarogawa Masakin, Muroga Mitsumasa, etc., the Kita Shin Sho such as Saito Asanobu could not achieve more results, and could only set fire to and plunder the castle towns and villages in various parts of the Takeda Domain. However, Sanada Yutaka did not have time to take care of Saku-gun, so more than a dozen castles around Komoro Castle, including Iwa Castle, Oi Castle, Shiga Castle, Maeyama Castle, Imai Castle, Hatanda Castle, Hinata Castle, Moriyama Castle, Otori Castle, Arayama Castle, and Nozawa Castle, were successively captured by Honjo Shimanaga's army, and the Takeda family's Suwa Zenkata Warriors (Suwa Fifty Cavalry) went to support Saku-gun, such as Senno Tanba Mamoru, Chino Yamajo Castle Irimichi, Chino Izu Irimichi, Tomoga Kiimori, Yamato Shomono, Suwa Uemon Captain, and Kosaka Fujizo.

While attacking the castle soldiers in Saku County that had not yet surrendered, Honjo Shiranaga also actively transferred the wild samurai and ronin in Saku County. Among them, Hiraga Masayuki (son of Hiraga Genshin's eldest son, Hiraga Masakatsu), the grandson of Hiraga Genshin (Hiraga Naruse, Hiraga Genshinsai, Hiraga Genshin, and the lord of Haikou Castle), and Oi Masanari (son of Hiraga Genshinji, Oi Masatsu), who had been dormant in Asamayama for many years, and when Honjo sent someone to recruit them, they immediately expressed their willingness to follow the Uesugi family and quickly led their subordinates to raid the old leaders of Hiraga Castle, Haikou Castle and other places.

However, after the Suwa Ancestors led by Masashi Hoshina lost their troops in Saku County, they had to flee in a hurry in order to avoid being cut off by the wild samurai and ronin mainly from the Hiraga people, and quickly withdrew into Suwa County to hold on and wait for reinforcements.

At the same time, the first castles that Koyama Asaki encountered in the hinterland of the Takeda family were Jokoji Castle, Hagiwara Castle, and Yama Castle. In order to prevent the Takeda family from not having enough financial and material resources to prepare for war in a short period of time, Koyama Asakyuki decided to first loot the mines in the Takeda family's domain, such as Akizuki Gold Mountain, Otsuki Gold Mountain, Kurokawa Gold Mountain, and Sutama Gold Mountain, and then invade the territories of powerful ministers in the Takeda family county, such as Oyamada Nobushige and Kato Keitada, forcing Takeda Shingen not to dare to lead the Koshu people out as easily as before.

Although the Uesugi family was strong, it was not strong enough to immediately destroy powerful daimyo such as the Takeda family and the southern family. Since the capture of Shimono and Changlu by the court, he began to focus on the territory and diplomacy, and has done a series of steady things.

First of all, Asadachi personally intervened in the war of Kitadewa, and under his mediation, the Anto family and the Tozawa family negotiated a truce, and then the daimyo of the two countries of Tohoku Ou arrived in Aizu-Wakamatsu Castle to meet with Asada. As long as it was a daimyo, Chaoding let them all get the Andu, and each of them received three Wu clothes and one hundred taels of silver.

On the other hand, Anton Aiji presented five good horses, three eagles, ten swords and a large amount of wood to the court; Tozawa Michimori presented three good horses, an eagle, and five swords to the court; Soma Yiyin presented ten good horses, ten swords, and ten gold to the court; Utsunomiya Kento, Iwaki Kenshige, and Mogami Kenjing presented three swords each to the court; Si Bo Quanzhen presented five good horses, three swords, and ten pieces of gold to the court; Tamura Takashi presented ten good horses and five swords to the court······

After the Ou daimyo such as Anton Aiji, Soma Yoshiyin, Spo Kanma, Utsunomiya Kento, Iwaki Kenshige, Mogami Kenkei, Tamura Takaaki, and Tozawa Michimori presented gifts to Asada, they also successively suggested that Asadachi defeat the southern family as soon as possible and send troops to Kamiraku in order to establish a hegemony.

Chaoding was very satisfied after listening to it, but he still couldn't accept it. Because at present, the court still needs to complete the stability of the generals, defeat the southern family, defeat the Takeda family and other affairs, otherwise it will not be possible to send troops to Shangluo smoothly.

However, in view of the fact that all the Okuwa generals had surrendered to the Uesugi family, the court decided to divide the positions of the Okuwa generals Kamakura Prefecture (Kanto Prince) as the representative of the Kanto Prefecture: Soma Yoshiyin served as the Karafune Shoge (in charge of foreign documents and foreign trade affairs) and also served as the assessor; Takashi Tamura served as the head of the Zen law (the monks who managed the monasteries) and served as the assessor; Anton Aiji served as the minister (responsible for the construction of palaces and residences); Tozawa Michimori served as the assessor (the department that deliberates on government affairs and adjudicates lawsuits, with a capacity of 24 people, of which only those who participate in routine assessment are called [Shi Assessors], and the rest are called [Birth Assessors); Spo Quanzhen served as the assessor; Mogami Kenjing served as the judge; Utsunomiya Kento served as the judge; Kenshige Iwaki served as the assessor;

Aiki Anto, Yoshiyin Soma, Kanma Spo, Kento Utsunomiya, Kenshige Iwaki, Kenkyo Mogami, Takami Takashi, and Michimori Tozawa were overjoyed to receive their positions in Kamakura Prefecture, and soon returned to their respective domains. However, Asada did not expect that Kenshin was very dissatisfied with his approach, and went directly to Aizu Wakamatsu Castle to question Asada.

At the same time, the news of the Daidai's large-scale division of the Daimyo of the Eastern Province gradually spread to Kyoto, and Ashikaga Yoshiteru was very angry when he heard about this, believing that what the Asada's actions were no different from rebellion, and he was ready to issue an imperial letter to Takeda Shingen, Nanbu Harumasa, Asakura Yoshikei, Oda Nobunaga, Tomigashi Harumada, and other powerful daimyo from all over the country, giving them the name of the righteousness of the crusade against the Asada.

However, it was only after Ashikaga Yoshiteru calmed down that he remembered that Asadachi had successively defeated the famous samurai families such as the Oshu Detective Date Family, the Hashu Detective Mogami Family, the former Oshu Detective Osaki Family, and the Oshu General Governor Kasai Family, and had basically swallowed the Kanto Eight Kingdoms and the Okuwa two countries, and also united with the Daimyo of the Eastern Kingdom to support the Imagawa clan as the Kanto Prince; And Echigo Kenshin, not long ago, the Hokuriku Province of Noto and Kaga were completely pacified, and even the Echizen guardian Asakura family also took the initiative to befriend him, and the people of Echichu were about to be pacified, and Kenshin soon had the intention of sending troops south to attack the Takeda family. In addition, Kenshin and Asadachi formed the "Muyue Alliance" for a long time, stirring up wolf smoke all over the eastern country, engaging in small groups, and completely ignoring the authority of the Muromachi shogunate. Subsequently, Ashikaga Yoshiki posthumously recognized the Daimyo of the Eastern Kingdom who were divided into feudal positions in the Imperial Court under the advice of the shogunes such as Akechi Mitsuhide, Takeda Nobutora, Isshiki Awaji Mamoru, Jibe Fujitsu, Jibe Fujiami, Settsu Harimon, and Chiaki Teruji, so as not to make enemies with the Uesugi family, so that the Eastern Daimyo would still remember the existence of the Muromachi Shogunate, and so that the Miyoshi family would not dare to move.

After the Daimyo of the Eastern Kingdom were divided, they began to divide the powerful retainers into the important towns of Hokurichi. After all, Hokurichi is a bitter cold place, and the court does not plan to spend a lot of troops, material resources, and financial resources to attack there, and plans to use the strength of the Hokurichi to use the people of Hokuritsu to contain the southern family.
