In just one morning, the blocking battle ended, and before noon, the Tiangu reinforced by Suqian was slowly pressed in, and the recruits who practiced shooting were all strangled, and only the shattered corpses of Tiangu that were bombed were found on the battlefield. In less than half an hour, there was no panting Japanese army on the battlefield, and then, when the large army advanced, when the artillery crossed the bridge, thick black smoke rose, making the battlefield slip like beacon smoke and wolf smoke, and the thick black smoke columns exuded the smell of burnt meat, straight to the sky.

In Bengbu, Gu Zhutong's six divisions fought with the two divisions of the Japanese army reinforced by Suzhou, and they could not advance an inch in front of Gu Zhutong's defense line.

The number of artillery pieces in Gu Zhutong's hand was already the largest in the whole army, and with countless shells, the Japanese troops who reinforced Bengbu suffered heavy losses, and they were repeatedly defeated by counter-charges, and it was difficult to gnaw down the front line that stretched for seven or eight kilometers.

If it weren't for Yu Lei resting and waiting for the attack order, these Japanese troops would not have had a chance to fight for so long, and they would have been eaten by the artillery and the strong surprise attack of the advance army.

But Yu Lei couldn't rush in, he had already rushed forward, and if he went any further, he would fall into the encirclement of the Japanese army, and Lao Zhao's troops were not yet in place, so Bengbu was temporarily defended by Gu Zhutong, and his pace slowed down.

The Japanese army was captured in a series of nodes, and it was already ruthless, and the army continued to rush to Bengbu, to Suqian, especially Suqian, Huai'an in front has not been taken, just a lonely city, but the city is still in the hands of its own people, and there are at least 30,000 troops in the city, so it must be taken back.

But the Japanese army obviously did not expect that the advance army was the first step by step, Suqian, artillery gathered, and the army also moved there, and the army attacking Huai'an was only two divisions. The general will besiege Huai'an.

Dong Ku received Yu Ke's report that Huai'an had lost its role and that the main direction of the Japanese army's attack should be Suqian, so he ordered an attack on Huai'an.

Sun Tao did not move to Suqian with the army, and he was very relieved to hand over Qu Jungang there, and he wanted to see Dong Ku's surprise to the Japanese army. Let's see how a special unit trained by Liu Zhong fought after Dong Ku occupied Shanghai.

Zuo Boyang was also very interested, wanting to see what new tricks Dong Ku, who didn't know much about the art of war, but knew a lot of battle examples.

Following Dong Ku's order, a regiment of fighters rushed to the front from the rear, and then touched the Japanese positions that were occasionally bombarded by artillery fire.

"Captain, what are those jars they're carrying?"

Sun Tao put down the binoculars. Puzzled, asked.

Zuo Boyang was also curious, looking at Dong Ku with inquiring eyes, waiting for an answer.

"Ha Lu Ha! After a while, let the Japanese army position in front of you become the old king's furnace, and see if the little devil has the two hits of Sun Wukong. ”

Dong Ku sold it, but he didn't answer.

As an instructor, Liu Zhong did not squeak.

At this time, Miyake Koji did not care much about the attack of the advance army, except for focusing on defending a passage several hundred meters wide that was opened by the heavy artillery of the advance army. Hold. In his opinion, there is absolutely no problem.

The dust was filled, and the surrounding area of the position was covered with smoke and dust. The visibility was quite low, and the soldiers who set off later approached the position thirty or forty meters, and the Japanese had not yet noticed.

Sun Tao, Zuo Boyang, Liu Zhong and others held binoculars and looked at the position in front of them, although they could not see clearly, they also hoped to see the effect of the new weapon through the telescope.

Just as they held up their binoculars, looking through their eyes. One by one, shouts of being in place rang out on the walkie-talkie.

Liu Zhong glanced at Dong Ku, saw his head, and yelled: "Begin!" ”

With his roar, a special squad of threes and threes mounted a strange machine gun with no magazines, and a tube attached to the back of the gun. Straight through the two canisters on their backs, and then, in their sight, a flaming dragon spewed out the muzzle of the gun, straight across a distance of thirty or forty meters, rushing towards the exposed firing ports.

Rumble!

The dragon roared and crashed into the bunker, and flames several meters high rose and burned fiercely on the dirt.

Spitfire......

Sun Tao and Zuo Boyang glanced at each other, and they didn't know what use this could be.

But the Japanese soldiers in the tunnel were miserable, and the flames sprayed into the interior along the firing port, and then burned fiercely inside.

No matter where the flames fall, the burning force and adhesion are very strong.

A Japanese soldier close to the firing port desperately threw out the flames stuck to his body, but the more he pounced, the more the flames burned, and in just one or two breaths, the Japanese soldier howled miserably, rolling all over the ground, and his skin was completely swallowed by the flames in the squeak of the flames.

"Extinguish the fire!!"

"Get out of the firing port!!"

In the shouts of all kinds of fear, the Japanese army ran in a panic, they were no better than Sun Tao and Zuo Boyang, they knew what this thing was, this was a flamethrow! Something that was so powerful during the First World War.

Inside the trenches and bunkers, Zuo Boyang and Sun Tao couldn't see the effect, but the two of them quickly discovered something special.

The fire dragon erupted dozens of meters long, and most of it was left outside the earth-rock bunker. Supposedly, even if the flame is oil, it will not burn that long. After the fire dragon disappeared and the raging fire in front of it began, it was dozens of seconds, and the flame had not yet been extinguished, and it seemed that the oil had not yet finished.

What kind of fuel is this?

The two glanced at each other, and their eyes turned to Dong Ku's face, waiting for an answer.

Dong Ku looked at the hundreds of fire points that had risen, smiled and said: "This is a flamethrower, which is filled with thickened fuel oil, the combustion force is quite long-lasting, the adhesion is strong, and it is not easy to extinguish. ”

Flamethrower?

The two of them were not too shaken, because they couldn't see the situation in those bunkers, and of course they didn't know what kind of shocking effect the road would have.

But at this time, the Japanese soldiers in those bunkers were like going to hell, and the fire droplets sprayed into the bunkers burned fiercely wherever they came, and they hit the Japanese soldiers, unless they quickly took off their clothes and pants, otherwise, they would become burning men in a while. Stained with guns and ammunition also does not delay the combustion, especially the roof of the tunnel is supported by wood, the flame has found a good carrier, just a few breaths, in the Japanese army's violent coughing, the fire spread throughout the tunnel.

The air poured in through the firing port made the flames spread rapidly towards the exits of the tunnels in the rear, and in the whistling of hulala, they quickly devoured the Japanese soldiers who could not see the road due to the thick smoke and high temperature, and the miserable screams were probably nothing more than the eighteen layers of hell.

"Help me!!"

A Japanese soldier rolled and tried to extinguish the flames on his body, but the back and forth rolling only increased the area where the flames burned, but did not make the flames on his body show even the slightest sign of extinguishing.

The flamethrowers in a circle all quickly withdrew after they were finished, away from the edge of the position, and had no intention of spraying again.

They had barely been evacuated for three minutes when a roaring explosion suddenly sounded inside the bunker. Tongues of fire erupted from the blast, and smoke rose from the depths in the distance.

"Huh? What's on fire inside? ”

Sun Tao looked at the flames that erupted and the smoke coming out of the rear of the position, and asked in surprise.

"Inside is a wooden roof of the alley, and this thickened fuel actually ignited the wood inside......"

Zuo Boyang said to himself.

"Captain, what is this thickened oil?"

Zuo Boyang suddenly turned his head and asked.

"Oil plus six or six powder, very simple things."

Dong Ku smiled and said: "In this way, the adhesion is strong, it is not easy to extinguish, and the only way to get on the body is to use a fire extinguisher, or quickly take off your clothes, otherwise, you will be burned alive." As several people spoke, the smoke from the Japanese position, which was dozens of meters deep, became more and more intense, tumbling and rolling, and it had already covered the position.

Inside the bunker, the explosion became more and more violent, and the roaring explosion caused those firing ports to spew out tongues of fire several meters long, one by one, more like a volcanic eruption.

"That's ...... so"

Dong Ku looked at the smoke in the distance and smiled coldly and said: "We surrounded the point to send reinforcements, but the Japanese army wanted to stick to the bait and strangle us, there must be several layers of positions staggered inside, so far the other side has not shelled, obviously the artillery will only bombard when we enter the position, and it is to bombard their own positions!" ”

Zuo Boyang's eyes lit up, and he seemed to understand what Dong Ku meant.

At this time, a circle of bunker positions around Huai'an had become a real Laojun furnace, and the Japanese army was either burned to death or choked to death by the smoke in just a few seconds. As the wood in the tunnel burned fiercely and the temperature continued to rise, those bullets and grenades were roasted and blown up one after another, and few people inside could escape.

Miyake Koji was dumbfounded at this time, he didn't know what means the other party used to make the pit burn, but obviously the first line of defense was useless, and the troops of the two wings inside did not run out. At this point, he may regret that the tunnel was dug too long and there was no emergency escape route.

"Scouts get close to the bunker and see what terrain is behind it!"

The moment Dong Ku understood, he then ordered.

The scouts, who were lurking dozens of meters in front of the position, ran quickly under the command, and in the thick smoke, ran up to the ridge.

"Report to the command, the ridge is more than 30 meters wide, it is the shape of a dam, and there is another ridge 50 meters behind, and like the previous one, thick smoke is coming out of front of those ridges."

Listening to the shouting on the walkie-talkie, several people in the command headquarters looked at each other in surprise. The Japanese army actually set up such a position, apparently waiting for the advance army to rush into the position, and the machine guns and artillery fire on the opposite side will kill the soldiers who rushed into the middle of the two dams, and it will be a massacre!

If it weren't for the siege and not the attack, if it weren't for the test of new weapons, this time it would really be broken......

Dong Ku's back was cold.

He originally thought that the Japanese positions were all underground, and there was at most a flat river behind the soil ridge, but he didn't expect that the Japanese army would actually set up such a vicious defense, once they charged, and when they found out, they ordered to stop the charge, and they didn't know how many soldiers would be thrown into this fifty-meter death zone.

"Order the artillery positions to bombard according to the coordinates of the scouts, order the independent 01st regiment to approach, spray flames at the second line of positions in the smoke, and burn these bastards!"

Dong Ku's eyes flashed, and he ordered loudly. (To be continued......)
