Basically, the construction of coastal defense in ancient China officially started in the Ming Dynasty. Although the previous coastal defenses were not typical, not to mention the Spring and Autumn Period and the Warring States Period, even the coastal defenses during the Tang and Song Dynasties were not as strict as the Ming Dynasty.
Before the Ming Dynasty, such as the Spring and Autumn Period, the Warring States Period, and the Three Kingdoms Period, some vassal states bordering rivers and seas had naval divisions and conducted naval warfare and maritime offensive and defensive operations, but they did not yet have clear coastal defense facilities and fixed establishments.
And during this period, when the princes in the Central Plains were busy fighting their own battles, no one among the coastal princes would have thought that someone would attack them across the sea. How prepared could they be for that long coastline!
In this case, the expeditionary force sent by Oda Nobunaga made a sneak attack on Xuzhou. Xuzhou was caught off guard and could easily suffer a big loss.
Previously, due to the system, Wang Yu had sent people from the floating house to secretly signal the princes. For example, the people from the floating house pretended to be fishermen to warn the local governments, saying that they had discovered a large sea channel on the sea during fishing, etc.
Ways to prepare these coastal princes in advance.
After all, Li Xiang cannot inform the princes openly. Firstly, it is uncertain whether the princes will believe him, especially warring princes like Yuan Shao and Zhu Yuanzhang. Secondly, it is not easy for him to explain the information.
origin of.
However, although the floating house provided warnings in advance, the effect was quite limited.
At this time, Zhao Kuangyin was at war with Xian Zhen and others. In addition, Zhao Kuangyin, who was in Xuzhou, the place where the Fourth Battle of the Central Plains was fought, also needed to defend against other surrounding princes, and could not mobilize too many manpower to defend the seaside.
Besides, some fishermen reported the matter to local officials. These officials believed that some pirates were attacking, but these pirates could not alert Zhao Kuangyin who was fighting on the front line.
Moreover, the coastline is long, and even if you take precautions in advance, you still can’t tell where someone will attack! In this case, it is naturally difficult to take precautions!
Moreover, even if these officials were on guard, they would only think they were a group of pirates. Who would have thought that among these pirates they thought, there were not only powerful generals like Hatamatoro Tomo, but also Akechi Mitsuhide.
Famous generals, as well as resourceful people like Takigawa Kazumasu.
This level of configuration is simply not something a group of so-called pirates can afford.
And just when the Japanese army broke through a city, Li Xiang's system sound also sounded, and a mission quietly arrived.
Yuzhou.
Among the three counties originally occupied by the Sun family, Lu County, which was the place where they made their fortune, was forced to be handed over to the Yellow Turbans as a benefit. Cao Cao occupied one of the remaining two counties, and Yuan Shu and Zhao Kuangyin divided them.
The last one, and the battle between the two sides started in this county.
Although Xian Zhen is powerful and is known as the Marshal of Strategy, Tian Dan is definitely not a vegetarian. Both sides attack and defend. Even if Xian Zhen achieves some victory, it is basically a small victory and cannot affect the final battle situation.
Absolute direction.
But at this time, Zhao Kuangyin suffered disaster from the sky, and bad news began to reach him.
In the lobby, Zhao Kuangyin was discussing the war situation with his generals, but a general entered in a hurry after reporting.
"My lord, great things have happened. Japanese Japanese have invaded Donghai County! They massacred villages and destroyed strongholds, killing and wounding countless people."
While speaking, the general also presented a handwritten letter from Yi Yin, which contained Yi Yin's description of what he had done after learning about the whole matter.
Zhao Kuangyin went to the front line, while Yi Yin was responsible for stabilizing Zhao Kuangyin's rear.
Although when those officials reported to Yi Yin, they reported a pirate invasion. However, with a pirate invasion of 20,000 people, how could Yi Yin believe that these people were really pirates?
Yi Yin would not rashly send false information to Zhao Kuangyin before figuring out the true situation.
Therefore, Yi Yin immediately sent people to determine the situation. Based on the reported situation, Yi Yin finally made his own judgment.
These so-called pirates did not speak Chinese. As for the specific bird language they spoke, the person who went to investigate the situation could not tell clearly, but it was enough to know that it was not Chinese.
Moreover, attacking from the sea, they were not Han people. Coupled with the common height, Yi Yin suddenly thought of an ancient book he had read before, and then opened the ancient ruins to compare it, and finally set his target on the ancient book.
On the Japanese people described in.
There are not many descriptions of Japan in ancient books, only a few fragments. It only records that its area is probably on an overseas island. Since most Japanese people are short, they often call Japan a Japanese country, and its people are also called Japan.
Call them Japanese.
According to the available information, the Japanese are already the most likely culprits!
"Damn it!" When such bad news came, Zhao Kuangyin immediately checked the letter from Yi Yin.
Twenty thousand Japanese troops are not a small number. Moreover, these Japanese troops are simply like a swarm of locusts. They will wipe out even some ordinary villages wherever they pass, let alone county towns.
net.
Moreover, these bastards committed all kinds of evil during the raids. Burning, killing, looting and looting were just the most basic operations. All the people along the way were poisoned by them, resulting in heavy casualties.
"My lord, it is in vain that the son of the fourth and third princes of Yuan Shu, first did such a treasonous act as usurping the throne, and now he colludes with foreign enemies for his own selfish interests. He is really a person who destroys people's hearts!" After reading Yi Yin's letter, Zhao Pu said sadly and indignantly
He stood up and roared.
In this situation, seeing Zhao Pu looking so sad and angry that he wanted to kill someone, all the important civil and military generals in the hall were affected.
"Yuan Jiujiu is not a human son. My lord, he should announce his crimes to the world as soon as possible and call on the world to jointly fight against the treacherous thief!" General Chen Baxian's reaction was also very quick, and he followed Zhao Pu and roared loudly and sadly.
.
"Yuan Jiujiu is a traitor and is not a son of man!" The remaining counselors or generals who reacted quickly, such as Chen Deng, indirectly echoed.
"Yuan Shu is a thief, I swear to kill him!" Zhao Kuangyin stood up in grief and indignation, pulled out the sword from his waist and slashed the document in front of him into two halves. Looking at it like this, he seemed to be really firm.
I think it was Yuan Shu who did it.
Of course it was Yuan Shu who did it, and it must be Yuan Shu who did it!
In any case, let's put a shit basin on Yuan Shu first. After all, they are both enemies. Zhao Kuangyin has no psychological pressure at all for this approach!
If it was suitable, he really wanted to give Yuan Shu more of these shit basins!
