Zhao Jiayu's rear factory area.

On an anti-aircraft position on the top of a hill.

The commander of the air defense company, Wen Ye, looked away from the huge optical ranging and aiming equipment, and then looked at the huge quadruple 40 anti-aircraft gun in the center of the position, the corners of his mouth twitched, and said to Li Yunlong:

"Commander, let's stop this thing in the future."

"This anti-aircraft gun is really good. But this thing was originally intended for large warships, including the base, one door was close to ten tons, too heavy, and it was too cumbersome to transfer. ”

"It's still suitable for a duplex, and the big jeep can lead the run."

Recalling the process of transferring this quadruple anti-aircraft gun to the top of the mountain, Fumino felt numb in his scalp.

The road built on the top of the mountain is not suitable for walking on ten wheels of heavy trucks, let alone towing an anti-aircraft gun weighing nearly ten tons, in order to transfer this thing to the mountain position, he transferred a full 500 people, widening and leveling the road, and pushing and pulling, and it took most of the night to get it done.

"I'll get more duplexes in the future."

Li Yunlong nodded.

A full ten quadruple 40 anti-aircraft guns made his heart still ache to this day.

One door is comparable to a Sakata!

The reason why he changed this thing was to look at the ring protective gun shield that could protect the shooter, the ultra-dense firepower, and the complete set of shooting commanders that could improve the efficiency of air defense.

"Did you figure out the shooting commander?"

Li Yunlong then asked.

"Captain..."

Speaking of this, Fumino felt a tingling of his scalp again:

"I'll use this set of optical ranging, it's relatively simple, not much more complicated than the single-tube one, but that fire control radar also has a mechanical calculator, this thing is really..."

"The master knows how to use it, and he taught me for a while, but this aiming system requires five people to operate, and the master is too busy, and the repair shop and the explosives factory can't do without him."

The firing commander provided with the quadruple is not fully automatic, and works in a very primitive way.

First, the target needs to be visually discovered, then the radar operator controls the radar to continuously illuminate, and the distance and direction angle are measured, and then the data is entered into a mechanical calculator by three other controllers, and finally the firing data is calculated and passed on to the artillery crew.

It is very cumbersome and requires not only a high level of knowledge of the operator, but also a lot of training.

"It'll be fine in a while."

Li Yunlong comforted.

When Wang Gensheng completes the task, there will be at least two new masters.

It was at this time.

Woo woo woo ·

The air defense siren sounded, and at the same time, the telephone came with a report from the telegraph room of the regimental headquarters:

"Two devil reconnaissance planes flew from the direction of Taiyuan."

"Prepare for battle."

Fumino immediately began to gear up.

Watching the little devil reconnaissance plane fly around every day, he had long thought about shooting it down, but there was no way before, and the 40 anti-aircraft guns at a height of more than 3,000 meters were enough, but the reconnaissance plane was fast, and it was difficult to hit it at high speed.

But this time, with more advanced and sophisticated aiming equipment and a more powerful anti-aircraft artillery group, he can give it a try...

It's just that, contrary to Fumino's expectations, when he raised his glasses to look at the two devil reconnaissance planes, he found that the two reconnaissance planes gradually lowered their altitude.

"This is..."

Looking at the two devil reconnaissance planes that were ready to pass by at a height of one thousand meters, Fumino sneered:

"Looking for death?"

Passing at low altitude and high speed, if it was before, it was really possible to succeed.

The air defense company has not been formed for a long time, the shooters are inexperienced, and they are almost in the face of high-speed aircraft, but now, after so many air defense operations and so many shells, there is already some experience, plus the newly arrived optical sighting equipment, hum.

"Ready..."

With Fumino's order, the barrels of one anti-aircraft gun after another began to move, all pointing at the gradually approaching devil reconnaissance plane, and the observation group also kept an eye on the plane and began to measure the range sideways.

Air.

Two devil reconnaissance planes, one in the airspace at an altitude of 1,000 meters and one at an altitude of 500 meters, one left and one right, presented a cross shape and prepared to sweep over the factory area behind Zhao Jiayu at high speed.

The two guys cooperated to prepare to pass through the airspace of the factory area at high speed at the same time to disperse the anti-aircraft firepower, and in the back seat of the two devil planes, the two observers were concentrating on controlling the camera, preparing to shoot the factory on the ground.

······

At the same time.

Ping'an County.

After the second artillery company bombarded Pan County, the devils of Ping'an County were also afraid, and hurriedly moved the military camp to the city, and scattered and scattered to avoid serious losses from shelling.

However, as there was no attack for a period of time, and even the team that went out to patrol did not have an accident, the devils in Ping'an County have also gained a lot of courage, and they have more and more time to go out of the city, and the scale is getting bigger and bigger.

Today, another squadron of devils went out of the city and drove away along the road.

The little devil actually didn't really want to go out, after all, there was a ridiculously strong Eighth Route Army unit in the distance, with more people than the imperial army in the entire Ping'an County, and the firepower was also stronger than the imperial army.

But the location of Ping'an County is very important, there is a large coal mine around, a small iron mine, rich in products, and there is a wide highway directly to the Zhengtai Railway, which is an important occupation area of the imperial army, which is more important than Panxian.

Helpless, the devil can only come out to patrol, deter the surroundings, and show a sense of talent, otherwise continue to nest in Ping'an County, I am afraid that the independent regiment has not yet come, and there will be problems in other places.

The three brigades in Ping'an County, patrolling in shifts, today is the third squadron-scale operation, and it is a squadron of the Mazaki Brigade that went out of the city, that is, the squadron that was ambushed by Zhang Dabiao and suffered heavy losses.

Of course, even if the independent regiment has not appeared recently, the devils are still very careful and vigilant, and sent a lot of cavalry to reconnoiter before leaving the city, and repeatedly confirmed the safety within a radius of six kilometers.

However, at this moment...

A hilltop two kilometers from the main road near Ping'an County, where the terrain is complex and rugged, and the people are inaccessible.

A squad of ten independent regimental reconnaissance fighters is hiding here, and the soldiers are concealed with weeds to assist in concealment.

Five warriors were on alert, two warriors were holding large observation glasses to look at the devils patrolling along the road in the distance, and the other three warriors were operating a radio station, and the long antenna had been erected high.

"Report to the commander of the rock company, the devil has come out and is marching along the road to the earth and stone fort, the direction is..."

The telegraph operator directly reported the distance of the devil.

"Okay, stay hidden, and report the impact point in time to assist in correcting the shelling."

Iwamori's voice came from inside the microphone.

At the same time, seven kilometers away, six Bofors mountain guns raised their barrels high, and six gun crews were also on standby behind the cannons.

"Ready."

Iwamori looked at the position.

This time, it was not the original six old artillery groups transferred from the headquarters and brigade headquarters that were responsible for the shelling, but the members of the reserve artillery groups trained by the independent regiment itself.

In this mission, the squadron of devils on the shelling patrol was only incidental, and the focus was on training new artillery groups.

"Open fire."

The red command flag fell, and the six Bofors mountain guns burst into flames.

Subsequently, according to feedback from forward observation posts, these long training periods, but the gunners who lacked real combat experience quickly completed the calibration and quickly proceeded to the next round of shelling.

Also at the same time.

Another place.

Heyuan County.

Wang Chengzhu also took his second artillery company to fire at a large artillery tower of devils, and similarly, this time it was also the new artillery group that operated the artillery.

At the signal of Li Yunlong, both Yan Sheng and Wang Chengzhu accelerated the training of new artillery units to lay the foundation for the upcoming expansion of artillery units.

Fortunately, the independent regiment has a sufficient reserve of talents, the soldiers generally have a good level of knowledge and culture, the losses of the artillery units are small, and the additional ranks are constantly sending outstanding personnel from afar, as well as a large number of artillery shells for actual combat training, and the training of the new artillery group is going smoothly.

·····

In the afternoon of the same day.

Taiyuan.

The first sentence command.

Gibbon sat in his chair and looked at the information he had recently gathered.

Since the last time the Independent Regiment shelled the Panxian camp and the Niangziguan railway station, he made some targeted arrangements, which proved to be very effective, and Li Yunlong only shelled the camp of the Imperial Association near the Zhengtai railway line once.

Jingle Bell··

Suddenly, the phone rang, and Yoshimoto didn't think much about it, and took the phone casually.

"General."

Judging from the voice, Yoshimoto could tell that it was the captain of the flying group who called.

"Two reconnaissance aircraft were shot down by a separate regiment."

"Nani?"

Gibbon frowned:

"What's going on?"

The Flight Captain explained:

"Today, I sent two reconnaissance planes at low altitude and high speed to reconnoiter the factory area of the Independent Regiment in preparation for the bombing, but unexpectedly, the anti-aircraft firepower of the Independent Regiment was stronger than before, and a large number of multi-mounted 40 anti-aircraft guns appeared."

"The two reconnaissance planes were all shot down in the airspace of the independent regiment, and the two pilots and two observers were all shattered."

"Yaga..."

Yoshimoto scolded:

"Waste."

But he could only scold angrily, because of the low-altitude and high-speed reconnaissance, he agreed.

Hanging up the phone, Yoshimoto rubbed his forehead, took a deep breath, and then slowly spit it out, which calmed his sexual mood.

The loss of two reconnaissance planes, as well as the fact that the anti-aircraft fire of Li Yunlong's independent regiment increased again, were not easy to digest.

Not long after the phone hung up, a staff officer ran in:

"General, Heyuan County reported that the artillery towers on the edge of the two roads were shelled by heavy artillery, the artillery towers were destroyed, and more than half of the troops stationed there were lost."

"Heavy artillery!"

The corners of Gibbon's eyes jumped, and then he gritted his teeth and slowly spit out three words:

"Li Yunlong."

Don't think about it, bombarding the turret with heavy artillery, only Li Yunlong can do it.

But what Yoshimoto didn't expect was that the staff officer hadn't finished the report yet:

"The Ping'an County garrison reported that the patrol squadron was subjected to long-range artillery shelling, and a squad was killed or wounded."

"Long-range shelling."

Hearing this, Gibbon suddenly let out a long sigh, full of helplessness.

Don't think about it, this must have been done by Li Yunlong, fortunately, in a squadron and two turrets, the losses were very slight, and the loss of the reconnaissance plane made him feel heartache.

"Yaga··"

After the staff officer left, Yoshimoto scolded weakly.

The loss of two reconnaissance aircraft, the increased anti-aircraft fire of the Separate Regiment, the artillery towers were shelled, the patrol squadrons were shelled, four bad news in a row were received in one day, and then, he did not have effective countermeasures, and there was no way to even retaliate.

It made Yoshimoto feel tired.

After calming down a little, Yoshimoto made targeted arrangements, ordering the county town close to the independent regiment to reduce patrols and build anti-artillery holes at the bottom of the turret.

After that, he said to himself:

"It should be fine next time."

Recently, he sent the two new brigades to the vicinity of Li Yunlong, focusing on strengthening the vigilance of the railway.

·····

The next day.

Li Yunlong came to the outside of the repair shop.

"Commander."

Sun Desheng reported to Li Yunlong:

"Three hundred and twenty-seven new pallet trucks have been built and all of them have passed the load test."

"Hahaha, that's good...

Grand Master Li was very satisfied.

After Zhang Wanhe sent a group of outstanding talents, the production of new plate cars accelerated, and with the steel provided by Kong Jie and Ding Wei, 350 plate cars with rubber tires and steel plate shock absorption were produced.

Three hundred and twenty-seven vehicles, leveling the road, each carrying 1.5 tons, that is, close to 500 tons, replaced by steel rails, that is, 7.5 kilometers.

Subsequently, he came to the regimental headquarters and called the telegraph operator:

"Send a report to the new 1st and 2nd regiments. High-speed their 'steelmaking' battle plan began. ”

With a railway of more than five kilometers, such a big move, the independent regiment was a little difficult to solve, and Li Yunlong decided to call Kong Jie and Ding Wei.
