Bright Sword Military System

The silo was discovered by the devils on the seventh day.

During this period, Okamura Ningji's countermeasure was to resume the use of scattered heavy artillery to bombard Yuncheng. If there is any change, it is to evacuate only during the day and night.

It can be said that Neiji Okamura has no other way.

In the face of the "special bomb" of the Eighth Route Army, the imperial army can't do nothing, can it?

If so, does that mean that you have surrendered?

Yuncheng doesn't need to fight anymore?

As a countermeasure, scattered artillery is still feasible.

Because this can not only continue the bombing of Yuncheng, but also avoid the loss of too many artillery... Even if it is bombed by the "special bomb" of the Eighth Route Army, it will only lose one artillery at most.

On the other hand, Neiji Okamura also hopes to know how the Eighth Route Army evaded the detection of the aircraft of the Imperial Air Force and launched the "special bomb"...

If the imperial army did not have heavy artillery to be the target of the Eighth Route Army, the Eighth Route Army would of course not launch "special bombs".

If the Eighth Route Army does not launch "special bombs", it means that Neiji Okamura may never know how the Eighth Route Army launched them.

Therefore, Neiji Okamura actually used these scattered artillery as a kind of bait.

Wang Xuexin also had to respond to Neiji Okamura's scattered tactics.

The reason is simple. If you feel that the number of one or two guns is too small to threaten Yuncheng, what about three or four guns?Will it become seven or eight gates in a few days?

In this regard, the "High Fire" troops are still strategically passive.

This is mainly because the strategic goal of the "high fire" troops is to protect Yuncheng, and Yuncheng is a fixed target and it is also very large. It is not difficult for the devil's heavy artillery to hit it, but it is not so easy for the "high fire" to hit the devil's heavy artillery up.

In order to improve the hit rate, Wang Xuexin continued to send more troops to build silos during this period.

Eleven silos were modified in seven days, so there are eighteen silos in total... Basically, all the silos that can be transformed with mines have been modified, and the next step is to dig tunnels, which is much slower than before.

As the number of silos increased, another problem became apparent: a severe shortage of telephones and telephone lines.

Before, Wang Xuexin required each silo to be equipped with at least five telephones: one for the command center and one for the air defense guard posts in each of the four directions.

In this way, no matter which direction, as soon as the devil plane is found, the command center can be notified immediately, and the command center will immediately stop the launch.

Therefore, the silo can "not launch when there are devil planes nearby", that is, keep the devil's secret.

There were no problems at the beginning, but as the number of silos increased, the telephones and telephone lines couldn’t keep up...Although telephones are not very expensive things, the Eighth Route Army captured a lot from the enemy, but the army’s demand for them is also high. It is quite large. In principle, each line of defense needs at least two phones to complete the command. In the battle on the front line, relying entirely on the communication soldiers to give orders will often miss the opportunity of the fighter, which can not be sloppy at all.

So the "high fire" troops could only use the old method: early warning by pulling ropes.

To put it simply, it is to dig a communication ditch in the ground. The straight one is the best, and the curved one is also acceptable, but it is necessary to install rollers at the corners, and then tie a hemp rope inside, and pull the hemp rope when the plane comes from the sky. , the bell on the other end rang.

In principle, this is not so different from a telephone.

Because the early warning required by the silo is actually very simple, that is, there are aircraft and no aircraft, and there is no problem with this method of early warning.

The problem is that……

These hemp ropes were bought from fellow villagers, and they were connected in sections.

It’s okay to connect a segment. The soldiers are all connected very carefully, so they are worried that they will be interrupted in the middle.

The problem is that some of the twine comes from a pig butcher in Yuncheng, whose twine is often used to bind pork...

Needless to say what the result is, the wild rats in Shanxi are big, not counting the tail, just more than ten centimeters in length, and they can gnaw the hemp rope through the communication ditch three or two times.

The one who discovered this secret was Captain Ogura, a devil who was driving "Zero War"... The speed of "Zero War", if it flies at the fastest speed, it can reach 8.8 kilometers per minute.

This "Zero War" cruised in the air at a medium speed in order to find the launchers of the Eighth Route Army.

The reason why Neiji Okamura sent the precious "Zero War" to perform cruise search missions in the air has his own reasons: with the endurance of "Zero War", it can cruise in the air for a long time without frequent return to the airport to take off and land. Actually saves fuel.On the other hand, because of its fast speed, it can intercept the enemy's "special bomb" in case it encounters it.

At this moment, a puff of smoke suddenly rose from below, and a "special bomb" flew into the sky from the bare mountain.

Captain Ogura couldn't help being stunned when he saw this scene. He thought he was wrong, so that he forgot to chase the "special bomb" at that moment.

After thinking for a few seconds, Captain Ogura decided that he should not pursue this "special bomb" and that he should find out how the Eighth Route Army launched it.

Therefore, Lieutenant Ogura immediately turned the nose of the plane and returned to the hill that he just passed, and then flew close to the smoke area at low altitude regardless of the danger... This is quite dangerous for the pilot, especially in mountainous areas. It can destroy the Ogura machine and kill people.

Then Captain Xiaocang saw clearly that the smoke was coming out of two caves, and there were still a few people near the cave entrance, busy using things to cover the cave entrance and put on a camouflage...

Captain Ogura hurriedly reported to the airport: "Your Majesty, there are no launchers, they are 'special bombs' launched from caves. I guess, there are camouflages at the entrances of these caves, which are opened before launch and covered after launch. So We never found out!"

Information soon spread to Neiji Okamura.

Neiji Okamura couldn't help scolding: "Bastard, these Eighth Route Army are too cunning! They actually thought of this method to hide the launchers in caves and tunnels!"

Yoshio Shinozuka also found this problem very difficult, and he said in surprise: "Your Excellency, if this is the case, then wouldn't our aviation team have nothing to do with it?"

To be precise, it is not impossible, but the efficiency is too low... Bombers can also bomb tunnels and caves, but the efficiency is so low that there is almost no way, and even if the tunnel entrance is blown up, the Eighth Route Army can easily repair it.

But Neiji Okamura didn't think so.

He stared at the map for a while, then said with a smirk: "No, Mr. Xiaozuka! Do you know why the Eighth Route Army camouflaged the entrance of the cave? That's because once we know the location of their tunnel, there will be a way!"
