"Fifteen?"

"Fifteen is just the minimum standard, Li Weimin, you select twenty company commanders from your division, you hold a meeting for them, let them prepare, and when we finish the matter, I will take them to the field for a field trip and on-site teaching, and each company must be responsible for an import and export!"

The Japanese army's underground fortifications must have stretched for more than a dozen kilometers or even dozens of kilometers, and Liao Fan planned to arrange a company in each of the 15 places, and of course he could make a few more places, and Liao Fan could also arrange more people.

After they have accurate information, they will arrange fifteen more companies of troops according to the detailed information, and they will have enough troops to deal with the little devils in the underground fortifications.

That night, Liao Fan took Niu Dan and them to dig holes, because with the general direction of the Japanese army's underground fortifications, their efficiency has also improved a lot, saving a lot of physical strength, in addition to having an hour of rest in one night, they dug fifteen holes in one go, although these fifteen holes have not been opened and only one person can pass through.

But when it comes to the critical moment, these fifteen holes can be filled with enough*, and as long as they explode, the holes can allow large forces to pass through.

The little devil didn't expect that the carefully prepared underground fortress would be found by the New 33rd Army and infiltrated. A hundred fighters who infiltrated the underground fortifications, after entering, dispersed in groups.

There were Japanese combat troops and logistics personnel in the entire underground fortifications, adding up to nearly 60,000 people, and a large part of the little devils did not know each other, providing good cover for the soldiers.

Moreover, after the soldiers entered the underground fortifications, they quickly figured out the password of the Japanese army, as long as they had the password, they could be unimpeded in the fortifications, and they also made friends with the little devils.

The underground fortifications are very large, so big that a hundred soldiers fall into the sea like a drop of water, and the soldiers must have a good relationship with the little devils, after all, there are many people and great strength, and at this time they can rely on the relationship of the little devils to understand the underground fortifications, so naturally they have to save effort, after all, they have to leave the underground fortifications before the next change of guard for the little devils.

The Japanese army has everything in the underground fortifications, and they must find out the important and fatal places in the underground fortifications of the little devils, after all, they are the attacking side, and if the Japanese army blocks their way in the underground fortifications, they will be completely frozen inside.

Time passed day by day, the people outside were digging holes, the soldiers inside were doing intelligence, and there was no intersection between the two sides. The people inside are waiting for the day to get out, and the people outside are waiting for the day to get in.

"These fifteen points on the map are the ones I have taken you to see, and once the battle starts, you will blow up the hole for me anyway, and then enter the underground fortifications! If you don't encounter Japanese troops, you will attack along the passage, and if there are Japanese troops, you will set up a defensive point on the spot and organize the Japanese army to approach the hole we have blown up! ”

Taking advantage of the time, in the evening, Liao Fan took the company commander to a field trip, and then assigned tasks to these company commanders on the map, so that they could keep in mind the standards of the operation, and they should not rush in or evacuate without authorization, after all, the underground fortifications were long and narrow, and as long as the Japanese army blocked a little, it would be difficult for them to move forward.

Therefore, Liao Fan's plan is to divide the Japanese army's underground fortifications into countless sections, so that the Japanese troops in the underground fortifications cannot take care of each other, so that the Japanese army's strength will be divided into countless small pieces, and when they are a little sleepy, they can trap the little devils who have no reinforcements in the underground fortifications to death.

"Okay, you all go back, if you have the conditions, you'd better take your own fighters to practice, so that we can reduce casualties!"

Now that they can get closer and closer to the dawn of victory, Liao Fan can see the hope of victory in the War of Resistance against Japanese Aggression with one more person, Liao Fan feels a little more relieved, after all, this war is also fought for themselves, and they also want to see peace and see a strong China rise in the East.

"I only arrange the troops for the import and export that we dug up, and you, the division commander, will arrange the rest!" After the company commanders left, Liao Fan said to Li Weimin.

After all, this battle still relies on large forces, and the Japanese army still has many strongholds around the underground fortifications, such as a brigade of the Japanese army stationed outside the fortifications, before the battle starts, they must drag this Japanese brigade or eliminate them as quickly as possible, and then they can launch an attack on the Japanese underground fortifications, otherwise their companies face the risk of being flanked by the Japanese front and rear.

Moreover, there are some strongholds of the Japanese puppet army around, although the strength of the troops is not much, and the combat effectiveness of the new 33rd Army cannot be compared, but if these Japanese troops frequently harass them, it will delay their speed of action and give the Japanese army enough time to transfer troops.

The first thing on the ground was to divide the Japanese forces, and the second was to trap the Japanese army, and then block the support of the Japanese reinforcements.

Finally, it was time for the Japanese army to change their defenses, in order to be precautionary, Liao Fan asked several company commanders to prepare in advance at the passage they had dug, once there was an abnormality in the underground fortifications, they would blow up a hole and directly attack it, and the soldiers who responded to them came out of the explosion, no matter how many people they could receive, at least one was alive, after all, they had key information in their hands.

However, since a hundred soldiers infiltrated the underground fortifications of the Japanese army, there has been no incident, there has been no movement, the most important thing is that these soldiers selected by Huang Changsheng are all experts in relationships, and they have a hot relationship with the little devils in the underground fortifications, and they all want to be called brothers, and no one treats them as outsiders.

It didn't go well when I entered the underground fortifications, but when I got out, it went very well.

"Boom Boom"

The troops of the Japanese army changed their guard before they got to the place, and of course, the troops ambushing them were arranged by Li Weimin, and he wanted to cover the hundred soldiers who slipped away from under the noses of the little devils. The battle lasted from afternoon to evening, and a hundred soldiers took advantage of the cover of night to successfully break away from the large Japanese army.

The little devils did not have too much doubt about the battles that took place, after all, they have been fighting with the Chinese army for so many years, and there are skirmishes almost every day, perhaps the Chinese have mastered the time for them to change their guards, as long as they change the time of the change of guards next time, there will be no more Chinese troops attacking them.

One hundred soldiers successfully returned to the defense area of the New 33rd Army, and these days they were careful in the underground fortifications of the Japanese army, not daring to expose themselves.

"This village is an entrance to the underground fortifications of the Japanese army, there are no more ordinary people in the village, and there are all small devils living in it, at least two squadrons of troops, they rest during the day and move at night!"

The soldiers began to mark on the map the Japanese underground fortifications they had written down and the deployment of troops in the surrounding area.

"No wonder we didn't find the entrance to the Japanese army's underground fortifications, the entrance to the underground fortifications was originally built in the village!" Li Weimin sighed, no wonder their scouts searched for so long and did not find the entrance to the Japanese underground fortifications.

"Go on! What was the deployment of the Japanese underground fortifications like! Liao Fan was also anxious to know the situation inside the Japanese army's underground fortifications.

"The width of the Japanese underground fortifications is about eight to ten meters, and the inside is capable of running away from tanks and trucks, and our group is scouting the distance between this section of the underground fortifications......"

The fighters of each group began to draw on the map what they had detected, and after they entered the underground fortifications, they carried out a detailed reconnaissance of the Japanese underground fortifications, and even the number of meters and a firing point were clearly marked.

"The little devil learned this from the earth mouse, this underground fortification really has everything!"

After listening to the soldiers' descriptions, Li Weimin had to sigh at the ability of the little devil to dig holes, not only did the underground fortifications have important facilities such as arsenals, power plants, and military cantonments, but even eating, drinking, and sleeping were arranged in an orderly manner, completely like half of a town.

"The Japanese army's underground fortifications have not been completed, they are still building firepower points in the underground fortifications, these firepower points are very hidden, and I can't go in to see it, each firepower point is separated, if it is attacked, destroying one can not completely destroy this firepower point, the Japanese army can also enter and fight!"

The firing points in the underground fortifications are all separated, it is difficult to destroy them with conventional weapons, and there is no * in China, this battle is not easy to fight.

"Look at the picture again and see if there's anything missing!"

The map is already detailed, but the Japanese underground fortifications are a terrible thing, and they can't be too careful.

For this map, they reconnoitred for half a month, and when they returned, they spent five hours together to draw what they had detected on the map, and this did not include areas that ordinary soldiers could not enter.

"Okay, I'll give you half a month's vacation, have a good rest, there are a lot of places to visit here in Datong, you can relax!" Liao Fan said to the hundred soldiers.

For half a month, these fighters were nervous and couldn't even sleep well, and now that they have completed their tasks, they can relax a bit.

"Li Weimin, you find a few officers who know how to draw, draw this map into three copies, you keep one copy, and then take Niu Dan and them to dig more than a dozen robbery holes above the Japanese underground fortifications!"

The defense of the Japanese underground fortifications was much more troublesome than Liao Fan imagined, and he had to make more preparations to reduce the casualties of his troops.

"I see!" Li Weimin nodded and left with the map.

"Brother Fan, this time why don't our special operations divisions take the lead, this is more difficult than street fighting!" Huang Changsheng took the initiative to ask Ying, and after seeing the reconnaissance situation that he believed, he knew that attacking the Japanese underground fortifications was not an easy matter.
