Xu Rui decided to directly hollow out the mountain of Fortress Hill and make it into an underground fortress similar to Songshan Fortress, and then specially reinforce the mountain on the front side of Fortress Mountain, and reserve a shooting hole for installing the four large-caliber naval guns removed from the devil cruiser.

The shooting hole of this design has great limitations in the angle of fire, and the adjustment range of the left and right angles and pitch angles is only 30 degrees at most, but it is enough for the Wusong Pass, because Xu Rui does not need to use the four fortress guns of the Wusong Fort to suppress the navy of the little devils, but only needs them to protect the shipwreck blockade line.

As long as the Songhu Military Division keeps the blockade line, it will be able to block the devil navy from Wusongkou!

In order to resist the little devil's large-caliber naval guns and heavy bombs, Xu Rui carried out special reinforcement on the front and top of the mountain of Fortress Mountain, according to the calculation results, unless the little devil transferred naval guns with a caliber of more than 500 millimeters, or threw 5,000 pounds of aerial bombs into Fortress Mountain, it would never be exploded!

But now, the devil's Yamato ship is only equipped with 400 mm caliber naval guns.

In other words, in terms of design alone, the fortifications of Wusong Fort are indestructible!

Of course, it should be noted that the project has just started and is far from finished!

Moreover, the successful completion of the project does not mean that the Wusong Fort is really indestructible, because in addition to throwing aerial bombs and bombarding the Wusong Fort with large-caliber naval guns, there is another way to destroy the Wusong Fort, which is to invest infantry to seize the periphery, as long as the perimeter of the Wusong Fort is seized, the fort will also fall.

So, in addition to the fortifications themselves, a large number of infantry auxiliary fortifications were needed.

First of all, on the anticline of Fortress Hill, it is necessary to build a large number of foxholes and communication trenches in advance to ensure that when the Devil Navy carries out artillery bombardment, the infantry of the Songhu Military Subdivision will have a place to hide, and when the Devils finish the shelling and dispatch the infantry, the infantry of the Songhu Military Subdivision can appear in front of the battery in time and launch a blockade.

In short, this is a very large system project, according to Xu Rui's estimate, half a month, it is barely possible to build a rough outline, about three months, the main structure can be basically built, but when the project is completely completed, how can it take six months, or even a year!

Now Xu Rui's biggest worry is that the devil won't give them enough time.

Fortunately, it is not without good news, at least it is enough for the workers to have ash.

When Wang Husheng rushed over with sweet potatoes, Xu Rui was personally taking the lead and digging the belly of the mountain.

Even digging the belly of the mountain is also particular, not simply hollowing out the belly of the mountain, if this is the case, before you hollow out the belly, the entire battery mountain has collapsed, and the workers will be buried alive, so you have to dig a row of caves first, first reinforce them with ash, and then dig a row of horizontal caves above this row of caves.

These excavated caves will be connected to the surface fortifications, and eventually build an intricate underground labyrinth, and when the third battle of Songhu breaks out, this underground labyrinth will become the biggest reliance of the defenders of Wusong Fort, whether it is the transfer of troops, the hiding of troops or the defense of artillery, this underground labyrinth will play a huge role.

"Lao Wang, you are not in charge of the tunnel project in Zhabei, what are you doing here with me?" Xu Rui asked.

Wang Husheng turned his gaze to the sweet potato, and the sweet potato told him about the Japanese woman he met.

"Woman? Or a Japanese woman? It's still so powerful! After listening to this, Xu Rui said in a deep voice, "If nothing else, this woman is a ninja, and she is the special forces of the Xiaoluyuan Brigade." ”

Wang Husheng said: "Lao Xu, it seems that our previous worries have become a fact, the beheading of the Commander's Department of the Fifth War Zone and the rumor that the beheading battle will be carried out against Chongqing Fangnan is really a devil's plan to divert the tiger from the mountain, after the veterans left, Xiaoluyuan's special operations team really came!" Fuck it! ”

Xu Rui frowned and said, "The question is, what was Xiaolu's original intention?" ”

The current situation is that the Okahara Special Operations Brigade is in the dark, and they are in the light.

The Xiaoluyuan Special Operations Brigade must have a clear goal when it comes to Shanghai this time, but they don't know it.

Wang Husheng frowned and said: "It would be nice if the shadow was still there, if he was there, he would be able to tell us clearly, what the Xiaoluyuan Brigade is doing in Shanghai, if you know this, we can open the net and wait, so that the Xiaoluyuan Brigade will become a meat bun and beat the dog, and there is no return, unlike now, we are simply black-eyed." ”

Sweet potato whispered: "Political commissar, we are not dogs." ”

Xu Rui shook his head and said: "That's nothing, the Xiaoluyuan Brigade came to Shanghai, after all, they are not here to travel, as long as they shoulder the mission, as long as they carry out the action, we can know, and we can make corresponding arrangements, as for now, just wait and see what happens, and don't need to deliberately watch out for anything." ”

In fact, in the face of special forces like the Xiaoluyuan Brigade, it is impossible to prevent it at all.

Although the wolf fang can deal with the Xiaoluyuan Brigade, but it will have to wait until the Xiaoluyuan Brigade shows its traces, and before the Xiaoluyuan Brigade shows its traces, the wolf's teeth are also powerless, after all, Shanghai is so big, and the wolf's teeth are only one hundred and ten people in total, how can it be possible to set up a net to make the Xiaoluyuan Brigade have nothing to hide?

Wang Husheng said worriedly: "If you're afraid, you'll be afraid, and when the Xiaoluyuan Brigade launches an operation, it's too late." ”

"No, it won't." Xu Rui shook his head and said firmly, "The Xiaoluyuan Brigade doesn't have such a lot of energy, and our Songhu Military Division is not so fragile, and it can't withstand any wind and rain." ”

Hearing Xu Rui say this, Wang Husheng was a little relieved.

However, Wang Husheng didn't know that Xu Rui was actually more worried than him in his heart, 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 special force in the real sense, if it is a head-to-head confrontation, Xu Rui is not afraid at all, but if it is a special operation, then the result is difficult to say, because a special force like this is extremely destructive!

For example, the military division headquarters, the eight arsenals hidden in the eastern and central areas of the concession, and even the Wusong Fort construction site and the tunnel construction site in Zhabei may all become the targets of the Xiaoluyuan Special Operations Brigade.

So Xu Rui's heart is also hanging.

(Dividing Line)

Almost at the same time, Mai Asahina had already joined up with the main force of Toshisi Oshihara's special operations team.

"Your Excellency, I want to review it for you." Mai Asahina paused, "I may have exposed my target." ”

After saying that, Asahina Mai told the process of being discovered and hunted down by the sweet potato not long ago, and then reversed, trying to capture the sweet potato alive and missing, from beginning to end, as it was.

When the mountain warrior heard this, he immediately became anxious and reprimanded: "Why are you so careless? ”

It was less than half an hour before Takeo Yamagami led the Second Special Operations Squadron back to Suzhou, and he didn't even have time to drink saliva, so he hurriedly came to Shanghai with Oshihara Toshisi to prepare to participate in the next stage of the sabotage operation, which was also hard enough, but fortunately, the members of the Second Special Operations Squadron were all ninjas, and they were all very full of physical strength and energy.

Xiao Luyuan Junsi waved his hand and said, "It's all a trivial matter, Xiao Wu, has I completed the task I gave you?" ”

"Hello!" Asahina danced for a moment, then took out a map from his satchel and said respectfully, "Your Excellency, I have drawn a detailed map of the dozen or so grain storage points I found!" ”

As she spoke, Mai Asahina handed the map to Toshimi Oshihara.

Oshihara Junsi took the map, unfolded it again, and then looked down again.

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 grain storage points she found, not only that, but Mai Asahina even marked the route of infiltration, the route of retreat, and which points on the way to retreat that could be set up in advance to block positions, all of which were clearly marked, and this was even an action plan.

"Yo Si." Xiao Luhara Junsi nodded happily and said, "Xiao Wu, you did a very good job. ”

Abe Yuji said excitedly: "Your Excellency Dazuo, with this map, we can follow the map and provide accurate guidance to the bomber group of the aviation regiment through signal flares, so that only a few dozen sulfur bombs are needed to blow up these dozen grain storage points on the map, Xu Rui's troops, just wait to be hungry!" ”

Takeo Yamagami also said sincerely: "Xiao Wu, I apologize to you for your recklessness just now. ”

"Hello." Asahina Mai nodded slightly and said, "Yamagami-kun, you are serious. ”

Okahara Junsi took out a pencil and quickly marked the dozen or so grain storage points on the map.

Then he said to Abe Yuji and Yamagami Takeo: "Abe-kun, your first squadron is responsible for targets from one to seven, Yamagami-kun, your second squadron is responsible for targets from eight to fourteen, Xiao Wu and Xiao Qing, you two follow me to the fifteenth target, you remember for me, you must not startle the snake before the operation begins!" ”

"Hello!" Yuji Abe and Takeo Yamagami paused.

"Now to the table." After speaking, Xiaoluhara Junsi raised his left hand and said in a deep voice, "The time is 2:20 in the morning, and the action time is 4:50 in the morning, do you all remember?" ”

"Hello!" Yuji Abe and Takeo Yamagami pause again.

Xiaoluyuan Junsi snorted lightly and said, "Let's go back and prepare for each of us first." ”

"Hello!" Yuji Abe and Takeo Yamagami paused for the third time, and then gathered several squad leaders and team leaders under their respective subordinates, and broke down the combat mission, and after a while, when the rest time came, Kokahara Toshisi immediately raised his right hand and waved forward, and the two special operations squadrons of the Okahara Brigade were immediately divided into fifteen groups and quickly split up.

In the blink of an eye, fifteen groups and more than a hundred people disappeared into the dark night.
