Xu Rui decided to directly hollow out the mountain of Fortress Mountain and build it into an underground fortress similar to Songshan Fortress. Then, he would specially reinforce the front side of Fortress Mountain and reserve shooting holes for installing the fortress.
Four large-caliber naval guns dismantled from the Japanese cruiser.
The shooting hole designed in this way has a very limited shooting angle, and the left and right angle and elevation angle adjustment range is only 30 degrees at most, but it is enough for guarding Wusongkou, because Xu Rui does not need to rely on the Wusong Fort.
The four fortress guns can suppress the Japanese navy, and it is enough for them to protect the shipwreck blockade.
As long as the Songhu Military Division maintains the blockade, it can block the Japanese navy from Wusongkou!
In order to resist the Japs' large-caliber naval guns and heavy aerial bombs, Xu Rui specially reinforced the front and top of Fortress Mountain. According to calculations, unless the Japs mobilized naval guns with a caliber of more than 500 mm,
Or drop a 5,000-pound aerial bomb on Fortress Hill, otherwise it will never explode!
But now, the Japanese's Yamato ship is only equipped with 400 mm caliber naval guns.
In other words, from a design perspective alone, the Wusong Fort fortifications are indestructible!
Of course, it should be noted that the project has just started and is far from complete!
Moreover, even if the project is successfully completed, it does not mean that the Wusong Fort is really indestructible, because in addition to throwing aerial bombs and bombarding with large-caliber naval guns, there is another way to destroy the Wusong Fort, which is to invest infantry to seize it.
As for the perimeter, as long as the perimeter of Wusong Fort is captured, the fort will fall.
Therefore, in addition to the fort fortifications themselves, a large number of auxiliary infantry fortifications are also needed.
First of all, on the reverse slope of Fortress Mountain, a large number of foxholes and communication trenches must be built in advance to ensure that when the Japanese navy launches artillery bombardment, the infantry of the Songhu Military Division will have somewhere to hide. When the Japanese navy ends the bombardment and dispatches the infantry, Songhu
The infantry of the military division can appear in front of the fort in time to launch a blocking attack.
In short, this is a very large system project. According to Xu Rui's estimate, it will take half a month to build a rough outline. In about three months, the main structure will be basically constructed. However, when the project is completed,
It will take six months, or even a year, to complete!
Xu Rui's biggest worry now is that the Japanese will not give them enough time.
Fortunately, there is not no good news. At least there are enough workers and cement.
When Wang Husheng came over with sweet potatoes, Xu Rui was taking the lead in digging out the belly of the mountain.
Even digging the belly of the mountain is very particular. It is not just a matter of hollowing out the belly of the mountain. If this is the case, the entire Fortress Mountain will collapse before you can hollow the belly of the mountain, and the workers will be buried alive, so a row of caves must be dug first.
, first reinforced with cement, and then dug another row of horizontal caves above this row of caves.
These excavated caves will be connected to the surface defenses, and eventually a complex underground labyrinth will be built. When the Third Battle of Songhu breaks out, this underground labyrinth will become the biggest reliance of the Wusong Fort defenders, regardless of the deployment of troops.
Whether it is hiding soldiers or defending artillery, this underground maze will play a huge role.
"Old Wang, if you are not in charge of the tunnel project in Zhabei, why are you here here?" Xu Rui asked.
Wang Husheng turned his attention to Digua, and Digua told him about the Japanese woman he met.
"A woman? A Japanese woman? She's so skilled!" Xu Rui said in a deep voice after hearing this, "If nothing else happens, this woman is a ninja and a special soldier of the Xiaoluyuan Brigade."
Wang Husheng said: "Old Xu, it seems that our previous worries have become a reality. The beheading of the commander of the Fifth War Zone and the rumor of a beheading campaign against Chongqing Fangnan were indeed a plan by the Japanese to divert the tiger away from the mountain. After the veterans and others left, Xiao
Luhara’s special operations brigade is here after all! Damn it!”
Xu Rui frowned and said, "The question is, what is Xiaolu's original intention?"
The current situation is that the Oluhara Special Forces Brigade is working in the dark, while they are working in the open.
The Xiaoluyuan Special Operations Brigade must have a clear goal when they come to Shanghai this time, but they don't know it.
Wang Husheng frowned and said: "It would be great if the shadow is still there. If he is here, he can tell us clearly what the Xiaoluyuan Brigade is doing in Shanghai. If we know this, we can set up a net to make the Xiaoluyuan Brigade become meat."
When a bun hits a dog, there is no return. Unlike now, we are basically blind."
Digua whispered: "Political Commissar, we are not dogs."
Xu Rui shook his head and said: "That's okay. The Xiaoluyuan Brigade came to Shanghai not for tourism. As long as they shoulder the mission and take action, we will know about it and make corresponding arrangements.
As for now, we just need to wait and see what happens, there is no need to deliberately guard against anything."
In fact, facing special forces like the Oluhara Brigade, it is impossible to defend against them.
Although Langya can deal with Xiaoluyuan Brigade, it will have to wait until Xiaoluyuan Brigade shows its signs. Before Xiaoluyuan Brigade shows its signs, Langya is powerless. After all, Shanghai is so big, and Langya only has a hundred and ten people in total.
How could it be possible to set up a dragnet so that the Xiaoluyuan Brigade could not escape?
Wang Husheng said worriedly: "Be afraid, because by the time the Xiaoluyuan brigade takes action, it will be too late."
"No." Xu Rui shook his head and said firmly, "Xiaoluyuan Brigade does not have such great energy, and our Songhu Military Division is not so fragile. It cannot withstand any wind and rain."
Hearing what Xu Rui said, Wang Husheng felt a little relieved.
But Wang Husheng didn't know that Xu Rui was actually more worried than him, but he didn't show it.
The reason why Xu Rui is worried is also very simple. The Xiaoluyuan Special Operations Brigade is not an ordinary force, but a real special forces. If there is a head-on confrontation, Xu Rui is not afraid at all, but if it is special operations, the result can be disastrous.
It's hard to say, because the destructive power of a special forces unit like this is extremely amazing!
For example, the military division headquarters, the eight arms depots hidden in the East and Central Districts of the Concession, and even the Wusong Fort construction site and the Zhabei tunnel engineering construction site may all become targets of attack by the Xiaoluyuan Special Warfare Brigade. Although the Langya Brigade is powerful
, but after all, the number of people is limited, and it is absolutely impossible to guard so many key points.
So Xu Rui's heart is also hanging.
(Dividing line)
At almost the same time, Asahina Mai had also joined the main force of Ogawara Shunsi's special operations brigade.
"Your Excellency Colonel, I want to review this with you." Mai Asahina paused and said, "I may have exposed my target."
After finishing speaking, Asahina Mai told the story from beginning to end about how she was discovered and chased by Di Gua not long ago, and then in turn, tried to capture Di Gua alive and failed.
Yamatakeo immediately became anxious when he heard this and scolded: "Why are you so careless?"
Takeo Yamagami led the Second Special Operations Squadron back to Suzhou less than half an hour ago. He didn't even have time to drink. He followed Shunsi Ogawara to Shanghai in a hurry to prepare to participate in the next stage of sabotage operations. It was hard enough.
, Fortunately, the members of the Second Special Operations Squadron are all ninjas, and they are all very strong and energetic.
Xiaoluyuan Junsi waved his hand and said: "These are all trivial matters, Xiaowu, have you completed the task I assigned you?"
"Hai!" Asahina danced for a while, then took out a map from her bag and said respectfully, "Your Excellency, Colonel, I have drawn detailed maps of the more than a dozen grain storage points I found!"
As she spoke, Asahina Mai handed the map to Ogawara Junsi.
Oluhara Junsi took the map, unfolded it, and then lowered his head to look at it.
Takeo on the mountain next to him immediately turned on his flashlight and illuminated the map.
On the map, Mai Asahina clearly marked the dozen or so food storage points she found. Not only that, Mai Asahina even included the infiltration route, the retreat route, and the points where blocking positions could be set up in advance during the retreat.
It's clearly marked, and it's even an action plan.
"Yoshi." Xiaoluyuan Junsi nodded happily and said, "Xiao Wu, you did a very good job."
Yuji Abe said excitedly: "Lord Colonel, with this map, we can follow the map and provide precise guidance to the aviation regiment's bomber group through signal flares. In this way, only a few dozen sulfur bombs can be used to destroy the bombers."
If these dozen grain storage points in the picture are blown up, Xu Rui's troops will be starving!"
Takeo on the mountain also said sincerely: "Xiao Wu, I apologize to you for my recklessness just now."
"Hai." Mai Asahina paused and said, "Shanzan-kun, you are serious in your words."
Oluhara Junsi took out his pencil and quickly marked a dozen grain storage points on the map.
Then he said to Yuji Abe and Takeo Yamama: "Abe-kun, your first squadron is responsible for targets one to seven, Shanma-kun, your second squadron is responsible for targets eight to fourteen, Xiaowu and Xiaoqing, you two
Come with me to Target No. 15, please remember, never alert the enemy before the action begins!"
"Hai!" Yuji Abe and Takeo Yamada nodded heavily.
"Look at the watch now." After finishing speaking, Junsi Okahara raised his left hand and said in a deep voice, "The time is now 2:20 in the morning, and the action time is 4:50 in the morning. Do you all remember it?"
"Hai!" Yuji Abe and Takeo Yamada paused again.
Oluhara Junsi snorted softly and said: "Let's go back and prepare ourselves first."
"Hai!" Yuji Abe and Takeo Yamada paused for the third time, and then called together several team captains and team leaders under their respective teams to break down the combat tasks. After a while, when the rest time came, Shunsi Okahara immediately raised his voice.
With a wave of his right hand forward, the two special operations squadrons of the Oluhara Brigade immediately divided into fifteen groups and quickly separated.
In the blink of an eye, fifteen groups and more than a hundred people disappeared into the dark night.
