There is also a reason why Nirayama Castle was able to become the birthplace of the Hojo family, since it was named Nirayama Castle, it was actually a flat castle, and the reason why it was named so was because it was backed by Nirayama Mountain, which is also one of the mountains of Izu Province, and its topographical advantage was that it was located in the middle of the mountains on all sides, which also led to the fact that Nirayama Castle was located on a mountainous terrain that was easy to defend and difficult to attack. But the problem is that the city of Jiushan is located in the mountains, after all, it is still built on flat land, and its mounds are all artificially built, not tall, so it is better to be born out of nothing!

has a fairly good terrain, and there are 3,000 defenders, and the Kuroda family army that needs to be faced is only less than 3,000 people, no matter how Shimizu Yasuei thinks about this matter, at least the Hojo clan and Takahashi Takamachi are very confident that they can defend this city, and the people under their command are also driven by the momentum of Takahashi Goras, they have become very energetic, and all of them believe that they can defend this city.

If the Kuroda family can't even take Nirayama Castle, then let alone Mt. Hirosawa after that, and don't mention Shimoda Castle after that.

But this has to be said the other way around, if once the Kuroda family captures Nirayama Castle, it is not the loss of Nirayama City itself in the first place, but the biggest loss is a blow to the entire Hojo family, after all, the land of Longxing was easily captured by the Kuroda family, how to say it is a discouraging thing, just like in the Deer Ding Ji, why does the Qing court have to guard its dragon veins tightly, isn't it a symbolic meaning?

If it is said that even if Nirayama Castle is really captured by the Kuroda family, then the defenders of the Hojo family will inevitably have a period of chaos, and it is very likely that the army of the Imate Tomo clan will take this opportunity to capture Mimasushi Pass, as long as the army of the Kuroda family can cross the Hakone Mountain, and then the entire Sagami country will almost not have too many barriers for the Kuroda family.

Originally, the country of Soma was based on Mt. Hakone as a barrier to the west, and if that really happened, it was really hard to say what the entire Hojo family would become at that time.

However, for the Hojo family, the better news now is that the various wealthy clans and national forces under their command have begun to slowly assemble towards Odawara.

As long as they can come over directly, the battle will be much easier for the Hojo family in the future, and the strength of the Hojo family is there, and it is very easy to get together twenty or thirty thousand horses.

Not to mention the loss of Izu Country, the only thing that needs to be seen after that is how much the Kuroda family attaches importance to the Hojo family and how many people they are willing to invest.

You must know that the Kuroda family is in Kai Province, and there are 40,000 troops led by Kuroda Rita, as long as half of these 40,000 troops come south, then the Kuroda family will almost invest nearly 40,000 horses in the Hojo family.

If there are 40,000 horses attacking the Hojo family, and they are all the elite of the Kuroda family, even if the Hojo family is the overlord of the eastern country, they should only be able to shrink to Oda's original defense in the end.

Just like in the past, when faced with the Uesugi family, the Takeda family, and the Toyotomi family in history, Odawara was used to make the strongest castle in the entire Wa country to defend against the Kuroda family's attack.

Even though it was once the birthplace of the Hojo family, Nirayama Castle is indeed still different, and the entire castle is composed of Honmaru and Nichimaru, and the area of Honmaru is not large. But there are several small oars arranged in Honmaru, which already looks very scary.

Ninomaru in Nirayama Castle allows everyone to roughly appreciate why the Hojo family built Odawara Castle in the future, because Ninomaru in Nirayama Castle is very large.

At least the Ninomaru in Nirayama Castle is much larger than the Ninomaru in an ordinary castle, and even if you don't tell others that this is Ninomaru, it is very likely that others will think that this is the Sannomaru of a certain city, in short, the area of Ninomaru in Nirayama Castle includes the area of Ninomaru to Sannomaru in other cities.

Why is this happening, because in Nirayama Castle, Ninomaru not only includes the various houses in the castle and the places where the soldiers lived, but also some farmland and functional areas similar to castle towns, when these things are also enclosed in the city, how can Ninomaru not be big?

If a city itself includes some farmland and castle town buildings, then even if it is besieged by the enemy, and it is a long-term siege, as long as the farmland can continue to produce agriculture, it is not afraid of this siege at all, because it is completely self-sufficient in food through allocation.

And the buildings of various castle towns can not only bring some commonly used handicrafts to the city, but also ensure that all kinds of military materials in the city can be produced continuously, so that the defenders can always have materials to defend the city, so it is really not very difficult to defend the city.

It is because of this that Odawara Castle has been able to withstand large-scale military attacks again and again in history, and it is not for nothing, at least in Nirayama Castle, you can already find a template of Odawara Castle.

When Hanafang Masayuki led his army of 2,700 men (and 300 men) he left in Yamanaka Castle to guard against a possible attack from the north. At the same time, it can be regarded as a confrontation with the defenders of the Hojo family in the Tohi area), and when he came to the outside of Nirayama Castle, Nirayama Castle had already closed the city gate and was ready to cage the castle.

For such an arrangement in the cage city, it was Hanafang Masayuki who was not surprised, after all, the Kuroda family was a strong side in Izu Province for the time being, even if it was the head snake Hojo clan and Shimizu Yasuei, they had to defend the Kuroda family's army.

In fact, until the end of the Hojo family was wiped out, Izu Province was not completely occupied, and it also carried out a counter-attack and defeated Hanafang Masayuki, which is a later story, and will not be repeated here.

At this time, the head of the Kuroda family, Kuroda Yoshitaka, suddenly made a move, he sent someone to contact the imperial court, and the imperial court was also very cooperative and suddenly issued an edict at this time.

This was an edict issued in the name of the Imperial Court, saying that the Hojo family did not abide by the agreement of the Imperial Court and rebelled against the rule of the Kuroda family, which belonged to the righteous side, so the Imperial Court issued a special order to point out the Hojo family as enemies of the Imperial Court.

In this era, to be honest, the imperial court under the leadership of the emperor no longer has much power, and even the imperial palace cannot be issued by decrees, and a so-called enemy of the court is nothing at all.

But the problem is that although the imperial court does not have any power of its own, the imperial court's speech still miraculously has a little effect, so in this case, when the Hojo family is accused of being an enemy of the court, it still has some influence in the Hojo family's territory, after all, this is an edict of the imperial court.
