In the face of the strong military strength of the Echigo army, in order to prevent the enemy from using the castle town as the front line of the attack, the Takeda army set a fire and burned the castle town of Iwaya Castle.

The flames rose red, and they looked particularly dazzling in the night sky.

The next day, the overnight march of Uesugi Kenshin's 3,000 banners crossed the Azuma River and arrived at the foot of Iwaki Castle, where they set up their main camp on a hill to the east of the castle, and the Ranryu Banner and the Biji Banner stood tall above the main formation. Coupled with the military strength of Saito and Sebe before, the Echigo army was even stronger.

At noon, the Echigo army rushed to Iwaki Castle all the way to Iwaki Castle, and Usami Joshimitsu, who had been recuperating at home, and Nakajo Fujishi, who had been recuperating at home, also led 4,000 troops to Azuma-gun.

So far, from Uesugi Kenshin downward, most of the famous Echigo generals have gathered here, including:

Biwa Castle, Usami Suruga Moriman, is known as the first wise general of Echigo, and is the originator of the Echigo-flowing art of war, and has been playing the role of Uesugi Kenshin military advisor before.

With Itajo, Naoe Yamato Mori Tsuna, in the Uesugi family's military service account, is the first mobilization force of the army. However, Naoe himself has always been stationed in the main camp with Uesugi Kenshin, and is rarely assigned to fight. Similarly, his ability to engage in domestic and foreign affairs is also very important in the Uesugi family.

Iizuka Gray Hair Castle, Gan Shan Omi Shoujing, because of his bravery and good fighting, was entrusted with the important task of the palace army by Uesugi Kenshin.

These three people, plus the Kakizaki and Izumi Shoujing families who died in the hands of Li Xiao, are collectively known as the Four Heavenly Kings of Uesugi, and they are the most famous generals under Uesugi Kenshin who were born in Echigo, and they are all gathered under Iwaki Castle at the moment.

In addition to the Uesugi Four Heavenly Kings, there are:

Honjo Castle, Honjo Echizen Shou is prosperous, born in the Chichibu Party.

Hirabayashi Castle, the color department repairs Katsunaga, and was born in the Chichibu Party.

Torisaka Castle, Nakajo Left Gatekeeper Fujishi, was born in the Miura Party.

Nitta Hair Castle, Shinfa Ota Owari Shou Chotsu, born in the Sasaki Party

Takemata Castle, Takemata right doorman Kiyozuna, born in the Sasaki Party.

The above five people all belong to the Echigo Yangbei people, Yangbei refers to the area north of the Agano River in Echigo Province, and the Yangbei people are composed of the Takezo Chichibu clan, the Omi Sasaki clan, the Sagami Miura clan and other families, the above three families are all descendants of famous families, from the original manor land of other countries, after entering the country Echigo, transformed into the local samurai Lang party, and the name of the place they received is taken as the Miao character of each family.

Previously, the Yangbei people had been the semi-reading force of Echigo, and they were opposed to the guardian Uesugi clan and the guardian generation Nagao clan. Later, Uesugi Kenshin unified Echigo, and Honjo, Shibe, Nakajo, Nittahata and others became his retainers.

Therefore, Yangbeizhong became a powerful army of the Echigo army, and went out to Kanto, besieged Odawara, and fought fiercely on Kawanakajima, and Yangbeizhong could be seen everywhere. And in the fourth battle of Kawanakajima, under the struggle of the Yangbei people, the Takeda army was given a lot of damage, and Uesugi Kenshin hereby issued the 'blood-stained feeling' to Katsunaga Shibe, Yasuda Nagahide, and Nakajo Fujishi, three generals from Yangbei.

At present, the mobilization power of the Yangbei army has reached more than 30% of the Echigo army.

In addition, there are Akata Castle, Saito Shimononomoru Asanobu; Fudo Mountain Castle, Yamamoto Temple Iyo Shoucho; From the Nagano family, the lord of Takaru Castle, Nagano Yegu and other generals, as well as the two fierce generals around Uesugi Kenshin, who were responsible for guarding the main camp, Yataro Kojima and Nagami Arakawa.

All the generals of the Echigo army led an army of 17,000 men under Iwaki Castle. During the Fourth Battle of Kawanakajima, Uesugi Kenshin was able to defeat Takeda Shingen's 20,000 Konobu soldiers head-on with 13,000 men.

And this time, he mobilized an army of 17,000 people to surround the small land of Iwaki City, and there were only 1,000 men and horses of Takeda Katsuyori and Li Xiao in the city, and the difference in strength between the two sides reached seventeen to one!

With such a powerful military force gathered in Iwaki Castle, it seemed that as long as everyone spat on it, it would be possible to flood Iwaki Castle.

It can be seen that Uesugi Kenshin is determined to win this time, vowing to take down Takeda Katsuyori and Li Xiao, and the shame of the battle of Hakuneyama. At present, the Echigo army did not immediately start the siege, but surrounded the three layers of the rock castle and the outer three layers.

The Echigo army set up roadblocks at various flat intersections to prevent Li Xiao from repeating the scene of Shirane Mountain charging with cavalry, and at the same time, they also guarded against the Takeda army's surprise attack on the Echigo army's position, and even broke through.

And in order to completely block the news, Uesugi Kenshin's Xuanyuan ninjas all went out to kill any suspicious characters in the territory of Azuma County to prevent information leakage, so that after learning the news, Kuzuzakikan sent reinforcements to Iwaki Castle.

On the night of Uesugi Kennobu's arrival, the sound of slamming trees outside the castle, the sound of boiling people, and the sound of thumping wooden stakes rang all night, and the soldiers of the Takeda Army in the castle were affected by this and stayed awake all night.

At dawn the next day, when Takeda got up, he looked out through the hole in the wheel, and saw countless tents and wooden huts erected, as if a castle town had been rebuilt on the current flat ground.

Relying on the huge manpower of the Shangshan Army, a complete camp was built overnight, with trenches vertical and horizontal, horse fences, watchtowers, and barracks one after another.

Not only was the Takeda Army dumbfounded, but even Takeda Katsuyori, Li Xiao, Sanada Masayuki, and Okuma Asahi who were watching from the Ninomaru Arrow Turf were also secretly tongue-in-cheek.

"Huihu Gong, he is really the god of the world!"

After watching Uesugi Kenshin's formation, Sanada Masayuki couldn't help but sigh.

Diametrically opposed to Uesugi Kenshin's bold and surprise attack style, the Echigo army's deployment appeared to be very sophisticated and rigorous, and it was not leaky.

Even the Great Bear Chaoxiu, who had been in the Echigo Army for many years, couldn't find a flaw, Takeda Katsuyori, Li Xiao, and Sanada Masayuki saw this complete defense, and they didn't even have the idea of attacking at night and going out of the city to fight.

At the moment, Takeda Shenglai, Li Xiao and they have only one idea, and they are ready to stick to and wait for help.

Fortunately, Iwaki Castle is also a fortified city, and there is enough food and water to hold onto, so that the defenders of the city can rest easy.

Iwazuki Castle is bordered by the Azuma River to the east, the 800-meter-high Mt. Iwazuma to the west, and the Azuma River cliff to the south.

The builders of Iwakushi Castle established Demaru here as the first line of defense to hold the passage, and Demaru was named Tengu Maru. After that, Ninomaru, Nakajo, and Honmaru are arranged up the mountain in order according to the terrain.

Iwakushi Castle has been operated by the Saito family for hundreds of years, and the Horikiri, earthen ramparts, stone walls, castle walls, and arrow turrets are all very complete.

At the beginning, when Takeda Katsuyori led the army to attack Iwaki Castle, he attacked the Tengu Pill for three days in a row, and he suffered a lot here, but he also failed to break through it, but fortunately, there were people within the Saito family who turned against the water, and the inside and outside should be combined to break through this fortified city, otherwise it was Li Xiao, Sanada Masayuki's ability, without the help of large siege equipment, I didn't know how to take Iwaki Castle for a while.

Now that the offensive and defensive sides are transposed, it is unknown whether Takeda Katsuyori will be able to withstand the onslaught of Uesugi Kenshin's 17,000-strong army with the fortified fortress of Iwaki Castle.

At present, the Takeda Army is desperately preparing for war, strengthening and repairing the castle in various places, vowing to resist the onslaught of the Echigo army.

And on the same night, an envoy sent by Uesugi Kenshin to persuade the Takeda army to surrender arrived at the foot of Iwaki Castle.
