The Japanese launched their attack on the third day.

The day before when the radar was turned on and the Eighth Route Army received positioning signals, it was just a test of the system.

As mentioned before, artillery detection radar and air defense systems are unstable. After being transported for a certain distance or used for a period of time, it is necessary to check whether they can operate normally.

The Eighth Route Army's tube radar system requires this step, not to mention the Japanese's relay radar system.

In the future, if the Eighth Route Army popularizes the transistor radar system, it can completely get rid of this tedious and unreliable step.

The Japs only started playing on the third day after the test. Wang Xuexin believed that this was because the testing process was not ideal and the Japs needed time to find out and fix the errors.

This is indeed the case. As a result of the Japanese test that day, only one artillery detection radar could be used normally, and the others all had various inexplicable malfunctions... These malfunctions are of course not "inexplicable", they are just a few relays in the transport.

Or the process used is just burned.

If it is the Eighth Route Army, they know how these systems work. They only need to input a few programs to quickly find the error location. This is like finding errors in the program, inputting some regular raw data, and analyzing and judging from the output results.

What part of the program went wrong?

However, the Japanese didn't know this, so they could only find out which relay was causing the problem one by one.

This almost caused the Japanese radar troops to collapse, especially the more complex air defense systems... The air defense system has a large amount of calculations and a complicated program. The number of relays used is several times that of the artillery detection radar. This requires finding one or two burnt or damaged ones.

A faulty relay is like finding a needle in a haystack.

However, the Japanese were very patient in this regard. After days and nights of sleepless fighting, they finally solved the problem and repaired two air defense systems. The two damaged artillery detection radars were unable to do anything due to lack of manpower.

In other words, in the end, the Japanese could only use two air defense systems and one artillery detection radar.

However, this does not affect the progress of the battle. Naosaburo Okabe believes that the artillery detection radar is just the icing on the cake. It is not important whether the air defense system is effective or not. The important thing is that the air defense system is effective and can help the imperial army gain air supremacy.

The battle started in the early morning, which Wang Xuexin guessed.

It's not hard to guess:

If the Japanese think they can have air superiority, they will definitely choose to fight during the day rather than at night, because air superiority cannot be exerted at night.

At the same time, in order to have enough time to attack the Eighth Route Army after seizing air supremacy and even drive it back to Zhangjiakou, the longer the daylight hours, the better.

So the best time to start the battle is in the early morning.

It was just getting dark that day, and Li Yunlong, who was still sleeping, was awakened by a burst of noise. Before Li Yunlong could ask, the guard hurried in and reported: "Captain, something's wrong! There's a fire!"

Li Yunlong suddenly sat up and ran out without putting on his military uniform. As he ran, he ordered: "Organize troops to put out the fire immediately!"

"yes!"

But Li Yunlong ran out of the house and looked in the direction of the two plumes of smoke. He was shocked and immediately called the guards back: "Send the order, no one is allowed to put out the fire. No matter where you are, everyone should hide one mile away and prepare for battle."

!”

"Captain..." The guard was confused when he heard this order. How could he give such an order?

Li Yunlong glared and roared: "Go quickly!"

"yes!"

Li Yunlong's order was right, because he could see at a glance that there was something wrong with the location of the fire: both fire points were near the Eighth Route Army's air defense system.

So this is not an ordinary fire, but a Japanese agent indicating the target to the bomber.

Li Yunlong secretly rejoiced that he had never been willing to sacrifice those radar soldiers... Radar soldiers were different from ordinary soldiers. Most of them were educated student soldiers, so even if they were sacrificed, they would not see death.

Save, how can an upright man like Li Yunlong feel at ease?

Now it's okay. The Japs setting fire and positioning gave Li Yunlong time to prepare... Since the Japs setting fire meant that the bombers were coming soon, he used another method to notify the radar soldiers to avoid it.

Li Yunlong's guess was correct, but within two minutes the Japanese bombers swooped down from the sky with a sharp roar.

With a "boom" explosion, both fire points were blown into a sea of ​​flames.

Immediately afterwards, another group of bombers arrived and dropped another batch of artillery shells. The dozen or so fighter jets following them also used their machine guns to fire at the area around the fire head...

This was carefully planned by Naosaburo Okabe. He sent a total of twenty bombers and ten fighter jets. These thirty planes did nothing but blow up the Eighth Route Army's artillery detection radar and air defense system.

Among them, the bombers carried out fixed-point bombing, while the fighter planes expanded their range and fired in all directions... Naosaburo Okabe knew from the air defense system he obtained that it was not only large in size but also very fragile. As long as one of dozens of cars was hit by a bullet, all of them would be paralyzed.

These thirty planes have been flying at low altitude since taking off from Duolun County... This is to avoid being detected by the Eighth Route Army's radar.

After they arrived at Jiulian Town, they relied on flame positioning, bombing and strafing, but there was a problem with the coordination between them... The Japanese agents lit the fire a little early, which gave Li Yunlong a little precious time to evacuate the soldiers from the fire point.

Come down.

The result made Li Yunlong very happy.

The air defense system cannot be maintained. Although some soldiers still drive cars when ordered to evacuate, the air defense system is basically useless as long as a few cars are bombed.

The artillery reconnaissance radar was not saved either. Due to combat needs, it was mostly placed at high places and had a very conspicuous antenna. Japanese pilots could blow it up without ground instructions.

The important point is that the radar soldiers only suffered about 20 casualties, and most of them survived and eventually retreated to Zhangjiakou.

Wang Xuexin secretly breathed a sigh of relief after knowing this information. Li Yunlong had done him a favor, so that Wang Xuexin no longer needed to find excuses to smooth over his inner guilt.

Then the Japanese launched a fierce attack on the town of Jiulian: swarms of artillery shells flew towards the town of Jiulian, and then more than 20 "Tiger" vehicles rushed towards the town of Jiulian with Japanese infantry like cow hair.

There is a tendency to submerge it in one fell swoop.

Flying in the sky were all Japanese fighter planes, at least thirty of them. Instead of swooping and strafing, they were circling around Jiulian Town, waiting for the Eighth Route Army's "La 5" to arrive for reinforcements.

The Eighth Route Army's "Pull 5" acted very cooperatively at this time. They pretended not to know that the Japanese had been equipped with air defense systems and flew forward to fight.

Then...anti-aircraft missiles took off one after another and headed straight for the Eighth Route Army fighter planes.
