"fire!"

Li Yunlong jumped to his feet and shouted.

Three mountain guns and two infantry guns fired simultaneously, aiming straight.

With several loud bangs, the eight small bunkers on the cliff were knocked down one by one.

However, the Japanese army's main bunker was never blown up, and three consecutive armor-piercing rounds failed to penetrate the main bunker.

This main bunker is Sou Fujimoto's favorite work. It is made of steel rods and concrete, and then poured with cement. The entire bunker is more than two meters thick.

Seven or eight V-shaped shooting holes appear from the inside out, which can radiate an area of ​​300 meters outside the command post.

Li Yunlong's eyes flashed sharply when he looked at the large bunker that even the mountain cannon could not destroy.

"Machine gun fire suppression!"

"Demoman!"

"Fuck me!"

Li Yunlong gave the order.

A battalion of more than forty suicide squads, with explosives and grenades hanging on their bodies, headed towards the Japanese main bunker.

The machine guns on both sides roared wildly, and machine gun bullets sent sand and rocks flying everywhere.

Soldiers continued to fall on the charging road, but the remaining soldiers continued to charge towards the bunker with a stern look on their faces as if they hadn't seen it.

The two mortar companies of Wang Chengzhu and Yao Shangwu frantically poured artillery shells into Yushe Middle School to cover the area. Even the Japanese sun flag was blown up and burned.

But the Japanese were hiding in the bunker, which was so large that even mountain artillery could not destroy it, and even mortar shells could not shake it.

However, the snipers and machine gun firepower of the independent regiment suppressed the Japanese firepower to a certain extent.

More than twenty blasters from the first battalion of suicide squads rushed to a position 40 meters away from the bunker.

In order not to be captured by the independent group, the Japanese finally took out their last trump card, poison gas bombs.

It is common for the Japanese army to use poison gas bombs on Chinese battlefields. According to incomplete statistics, under the orders of the base camp, the Japanese army used poison gas more than 2,000 times during the Tsinghua War, poisoning a total of 200,000 Chinese soldiers and civilians, and about 20,000 of them died.

.

The Japanese used grenades to fire more than a dozen poison gas bombs from inside Yushe Middle School.

As the explosion sounded, the charging soldiers quickly made moves to avoid it, but they did not feel the shrapnel, and balls of red and yellow gas burst out.

Caught off guard, all the kamikaze blasters were enveloped in poisonous gas.

There are mainly four types of poison gas bombs used by the Japanese military: green bombs, red bombs, yellow bombs, and tea bombs.

Green bombs are also commonly known as tear gas bombs, which are the least powerful and harmful; red bombs, which release poisonous gas that strongly stimulates the respiratory organs, commonly known as sneeze bombs; yellow bombs, which are erosive gas bombs

, can cause ulcers to the skin and mucous membranes after use; tea bombs, this kind of poisonous gas contains highly toxic poisonous gas, which can directly cause heart failure and death.

In response to the Japanese army's poison gas bomb tactics, the Eighth Route Army had specialized chemical defense cadres who constantly organized soldiers to carry out gas prevention training.

And prepared anti-virus equipment as much as possible.

And before attacking Yushe County, Li Yunlong and Wei Dayong knew that the Japanese army was preparing poisonous gas.

Due to limited conditions, although there were no gas masks, every soldier was prepared with gas masks, garlic, and towels.

The soldiers of the Suicide Squad Demoman took out the wet towels they had prepared in advance, wrapped them in garlic cloves and put them over their mouths.

Although these measures are simple, they can block irritating gases and play a basic protective role.

But the soldiers soon discovered that the simple gas masks had no protective effect at all. They suddenly became dizzy and fell to the ground one after another.

Seeing that the soldiers were motionless amid the poisonous gas, Li Yunlong's facial muscles were twitching and his teeth were clenching.

"The entire regiment retreats two hundred meters!"

Following Li Yunlong's order, the soldiers covered their mouths and noses with masks and retreated with a clatter.

"It seems that the devils not only used ordinary gas bombs, but also used the most toxic gas bombs. Our gas masks are ineffective."

All the officers at battalion level and above in the independent regiment gathered together to discuss countermeasures. Everyone looked solemn, and Li Yunlong was the first to speak.

This was not the first time that Wei Dayong saw the Japanese army using poison gas bombs.

In his memory, during the Battle of Xinkou, the Japanese army released poison gas bombs at the 27th Division position.

This group of devils are rigid-minded, "recruiting" bastards with poor tactical skills, and are ruthless and inhuman beasts.

They have no basic bottom line as a human being. When the war goes against them, they will not hesitate to use the most violent gas bombs to gain a chance of comeback!

"Fuck you!" Zhang Dabiao's eyes were bloodshot, "Commander, let's also use mountain cannons to release poison gas bombs on the Japanese to let them taste the poison gas!"

A battalion of more than 40 soldiers was wiped out like this. Zhang Dabiao wished he could tear these Japanese soldiers to pieces with his own hands.

"It's useless." Zhao Gang shook his head and said, "The devils have gas masks, and gas bombs have no effect on them."

"What should we do now?" Li Yunlong glanced at everyone, "Don't be so damn dumb, think of a solution quickly."

Li Yunlong glanced at Wei Dayong: "Wei Dayong, you usually have more clever ideas, why are you silent now?"

Wei Dayong said: "There are two ways."

"If you have a way, why don't you tell me?" Li Yunlong said, "Why are you such a bitch? This is not like your character."

"The safer way is to use earth excavation, dig a secret passage to the bottom of the Japanese bunker, and use explosives to blow it up," Wei Dayong said.

"This is a way, but the Japanese reinforcements may already be on the way now, and we don't have that much time."

Even if Li Yunlong rejected Wei Dayong's idea, the tunnel operation would take at least more than a day. Before the independent group could dig under the bunker, the Japanese had already surrounded Yushe County.

Zhao Gang was silent for a while, and then asked Wei Dayong: "What is the other way?"

Wei Dayong said: "Just like blowing up a city wall, use TNT explosives to make explosive packets, and then use thunder cannons to blow them up. However, this bunker is a bit weird and may not necessarily explode."

"Just use the flying thunder cannon!" Li Yunlong's face turned grim, "If one cannon doesn't work, fire two, and if it doesn't work, fire ten!"

Li Yunlong added: "I still don't believe it. Even if it is an iron wall, I will blow it up today!"

"yes!"

Wei Dayong replied and turned around to make the TNT explosive package with his own hands.

This kind of strong fortress is comparable to a city wall several meters thick. To be honest, he is not sure whether it can be exploded.

At this time, the roar of aircraft engines sounded in the sky, and it became louder and louder.

"Hide quickly!"

The expressions of the commanders and fighters of the independent regiment changed slightly, and they quickly found bunkers to hide.

Four Zero fighter planes flew over Yushe County at low altitude, making a buzzing sound.

But he didn't fire, as if he was looking for a target.
