In the second year of Yonglu, June 22.

Kenshin marched for a day and a night and crossed Iriyamaka to Karuizawa.

The Iwamurada Oi family, who was stationed in the area of Shinano and Ueno countries, waited until Kenshin's soldiers came to Nagakura Castle before they woke up and sent reinforcements.

Iwamurata Oi's retainer Takesha Kagamori Castle's residence of Hirodo Castle was the closest to Nagakura Castle, so it became the first reinforcement to go to the rescue of Nagakushi Castle.

However, the heavens didn't seem to want to give Takesha Kagamori a chance, and it was only after he hurriedly led his army to the west of Nagasura Castle that he found that the Uesugi family's bamboo finch flag had already been erected on the castle.

Takesha Kaga Mamoru looked at the bamboo finch flag fluttering in the wind on the head of the castle, so he could only stubbornly move forward. Because once Nagakura Castle is occupied by the Uesugi army, then the Uesugi army will be able to drive straight to the important town of Komori Castle, and even Odai Castle, the original base of the Iwamurata Oi family, will become unsafe.

"The people of the Takeda family are like this, and they don't know what to do? The city has been captured, and the reinforcements continue to be sent to death? Ganya Keichi stood by the big hand gate of Sannomaru and watched as he continued to move forward, and Takesha Kaga Moribe said.

"More than 100 defenders in Changcang City have been taken by our army, do they think that our combat achievements are not enough, and then they will send me to wait?" Hiroto Biwajima couldn't help but laugh when he finished speaking.

"Mamoru Ente, did you speak from the side of the Imperial House?" Gan Ya Kei asked Nagao Fujikei, who had just walked to the Otemon.

"The Goyagata Hall wants to send Murata-sama to fight, and the rest of the generals are preparing to attack Odai Castle and Plains Castle." Nagao Fujijing said helplessly. Originally, he offered to fight, but Kenshin felt that he wanted to give the young retainer some opportunities to make meritorious contributions, so he gave the opportunity to play in the war to Murata Hideyori. Murata Hideyori also lived up to Kenshin's trust, and led 500 troops out of the city without saying a word.

However, the army of more than 100 troops under the command of Takesha Kaga Mamoru was composed of peasant soldiers and conscripted ashigaru, which could not withstand the onslaught of Murata Hideyori at all. Immediately, the Takesha Kaga Detention Department from the Takesha Kaga Mori Department to the Takesha Kaga Mori and below were all killed in battle.

On the other hand, Oi Sadakiyo, the head of the Iwamura Da Oi family in Odai Castle, is anxious about Kenshin entering his domain. He knew very well that as long as Qianxin had a firm foothold here, once he could free his hands, then he would definitely have no good fruit to eat. Soon, he contacted the surrounding Yitian family, Banye family and other wealthy clans, preparing to unite to resist the invasion of Kenshin.

However, these actions of the Iwamurata Oi family are useless in the face of Kenshin. Kenshin ordered Ayukawa Kiyocho of Kunimine Castle to lead his army into Nagasura Castle before leading his army out of Nagakura Castle.

At the same time, Fukashi Castle Honmaru Daihiroma.

"Lord, something is wrong!" Kansuke Yamamoto limped into the Ohiro room.

"What the hell is it about Kansuke that makes you so alarmed?" It's the first time I've seen Kansuke Yamamoto panic.

"Uesugi Kenshin has led his army into the territory of the Iwamurata Oi family, and Nagakura Castle has been captured. If it were Sanada and the others, they wouldn't be able to resist Uesugi's tiger and wolf division at all! "Kansuke Yamamoto made a big announcement.

"What?! Kansuke, didn't you say before that Uesugi Kenshin couldn't pass through Nishi-Ueno? Could it be that the Uesugi Army flew over? "A Shinryu put the blame on Kansuke Yamamoto.

"This is indeed the old man's mistake. Unexpectedly, the people of Nishiueno were not out of the city, giving Kenshin the opportunity to pass through Nishiueno quickly. Kansuke Yamamoto said helplessly.

"Well, let's think about how to deal with it now!" Takeda Shingen's original plan to send troops to support Baba Nobubo, Zhujiao Torada and others also fell through.

"Now we can only ask the horse farm, Zhujiao and other departments to suspend the attack. And the lord needs to send a large army to the small prefecture and Saku county to set up defenses, and at the right time, concentrate the army and eat this Uesugi army in one bite. Kansuke Yamamoto recovered in an instant and came up with a plan.

"Kill a thousand, and lose eight hundred. It's not the first time you've seen the combat power of the Echigo Army. Whether it was the Aizu Ashina family, the Okuyu Mogami and Date families, or the Hojo family, which family had just been defeated, etc., which family did not suffer in the field battle? Komai Takahakusai shook his head and said.

"Nagano Shinano must have received someone's order to stay still, otherwise he wouldn't have come out of the city." Shimojo Nobuji said a detail that everyone ignored at this moment.

"Let's not talk about anything else, the maximum number of troops that Governor Oi Saemon can mobilize is only six hundred, and the same is true for the surrounding wealthy clans. Uesugi Kenshin led 5,000 troops into Shinano, and we must pay attention to it. Komai Takahakusai was worried.

"Order Mochizuki, Ashida, Aiki, Sanada and others to go to Komori Castle, and move the main camp to Shiota Castle." Takeda Shingen could only make this decision, he didn't want to lead the army to the rescue in a hurry. Because he still doesn't understand how Kenshin could be so bold as to attack Kore-gun and Saku-gun.

As Kenshin led his army into Saku-gun, the clouds of war in Kita-Shinano were instantly overcast.

Oi Sadakiyo gathered 3,000 troops in Odai Castle after uniting Sanada, Aiki, Ita and other wealthy clans. And Kenshin immediately led his army to capture the lax defense of Plains City.

When Oi Sadakiyo and the others were shocked to learn of the loss of Hirahara Castle of the Itada family, the Ita army immediately left Odai Castle under the leadership of Ita Nobuyori (the father of Ashida Nobumori and Ashida Shinbo) to return to his domain. However, on the way, the Yitian army was ambushed by Gan Li Jingzhi and the whole army was annihilated, and more than 500 people were killed in the battle from Yitian Xinke.

After the Yitian army was annihilated, the coalition forces of Oi Sadakiyo and others became even weaker. Because his brother had rebelled against Takeda Shingen several times, the Iwamurata Oi family was not trusted by the Takeda family, and its territory was repeatedly reduced. This is also one of the reasons why Takeda Shingen does not plan to do his best to support Oi Sadakiyo.

However, before the reinforcements sent by Takeda Shingen arrived, Oi Sadakiyoshi learned that Hiroto Castle, a branch city west of Odai Castle, had been captured by Oishi Tsunamoto, a reinforcement from the Uesugi army. At the same time, Miyantaira Castle, a branch city south of Hiroto Castle, was attacked by the Uesugi army, and the lord of the castle, Saunosuke Nagakura, constantly sent people to break through the siege and ask for help from Odai Castle.

When Takeda Shingen learned that another 2,000 Uesugi troops had entered Saku-gun, he immediately summoned Kansuke Yamamoto and Komai Takahakusai.

"Gao Hakusai, Kansuke, it seems that the Fujiwara town government has seen the intentions of the family. It is very likely that Nagano Yoshimasa and other generals of Nishiueno were indestructible at his behest. Shingen Takeda stated his conclusions.

"Definitely. Even the generals such as Omori, Honjo, and Ogasawara in Higashi-Ueno did not move, and did not take advantage of Kenshin's entry into Saku-gun to cut off her supply lines and back routes. Kansuke Yamamoto nodded.

"Send someone to incite the generals of Ueno to raise troops to rebel first, and then whether it is Kenshin or Fujiwara Town, there will be no time to take care of the war in Okushinano. In this way, the family will be able to capture Okushinano smoothly, and even send troops to Echigo in the future. Takeda Shingen is full of confidence in this.

"Most of the retainers of the Fujiwara Town Government in Higashi-Ueno are genealogy retainers and a family. Uesugi Keimitsu, Honjo Shiganaga, and Numata Yumitsu (quasi-gate) are all important places to guard as one of them, and Ogasawara Shinano Mamoru is the former Shinano guardian and has also been arranged by the Fujiwara Town Government to possess Ueno's Zhiyuki. I'm afraid that the Higashi-Ueno family will be difficult to adjust. Komai shook his head, he didn't think he would be able to make a difference.

"If the east is not good, isn't there still the west field? Although most of the kokuren lords who belonged to Nagano Shinanomori were his sons-in-law, they were all hostile to Kenshin. Once the strategy is successful, then humility will become a turtle in the urn! Kansuke Yamamoto was very supportive of Shingen Takeda's idea.

"Kansuke, I'll leave this matter to you." Takeda Shingen said with satisfaction.

After Takeda Shingen learned that Ida Shinmori had died in battle, he immediately sent someone to Yuanjiang to inform Ashida Shinbo, who had been transferred to Jiutou Township, and asked him to mourn and change. Then let Ashida Shinfu, the younger brother of Ashida Shinbo, inherit more than half of the family business of Ashida Yitian and serve as the lord of Ashida Castle.
