"However, for the Japanese army, these casualties are worth it in order to pave the way for the final attack.
At this time, other Japanese soldiers also began to prepare for the third wave of attacks.
However, their attack needs to wait until dawn, at half past four, which is the sleepiest time for ordinary people.
At the same time, this time is close to dawn, which is also the time when the opponent buys and the enemy is most likely to relax their vigilance.
If they can seize this offensive opportunity well, they can achieve unexpected results.
Maybe it¡¯s not impossible to break through the enemy¡¯s defensive position on the opposite side.
Behind the last wave of Japanese attacks were the Japanese gas bomb troops.
Before the final wave of attacks, they will release a large amount of poison gas they carry to kill the enemies on the opposite side.
With these poisonous gases, the enemy on the opposite side is likely to suffer huge casualties.
If they were more lucky, they might be able to knock down the enemy's position on the opposite side without any effort.
They have measured the wind direction and prepared the distance and dose of poison gas release.
Originally, this plan met with some opposition.
After all, if these poisonous gases crossed the city wall of Harbin and attacked the Japanese residents in the city, that would not be what they wanted to see.
However, fortunately, the captain of the poison gas unit made a guarantee that the poison gas they released would only spread to the vicinity of the defensive positions of the Fourth Army on the opposite side, and would never go further.
In this way, their plan was passed.
After Bai Rihui watched the Japanese army retreat, he felt tired and began to invade his body.
He yawned, and then said: "Tell the brothers, cheer up, I have to go back and sleep for a while."
With that said, he turned around and walked into the air-raid shelter.
According to the understanding of the soldiers of the Fourth Army, the two probing attacks by the Japanese army have not achieved any effect, so the possibility of the enemy launching a third wave of attacks is already very low.
What's more, dawn is about to come, and the little devils on the opposite side can't still launch sneak attacks on them after dawn. That would be meaningless.
The reconnaissance troops of the Fourth Army operating at the front also relaxed their vigilance.
At 4:30 in the morning, the Japanese troops in this direction began to release poison gas bombs in the darkness.
At the same time, the Japanese soldiers put on their gas masks, began to lie on the ground, and continued to advance forward.
In the darkness, the Japanese soldiers were like lizards crawling on the ground, crawling forward.
??Beside these Japanese soldiers, there are a large number of Japanese corpses.
Those were the Japanese soldiers who were killed by soldiers of the Fourth Army when they participated in the previous attack.
Some of them are not dead yet, but there is no need to save them.
Seeing the Japanese soldiers coming, the dying Japanese soldiers began to moan.
But the Japanese soldiers passing by them just looked at these people with some sympathy, and then continued to move forward, as if the person who groaned just now was just a cold corpse and had nothing to do with them.
This time, the Japanese attack concentrated more troops.
At the same time, more firepower was deployed in the rear of the Japanese army.
The Japanese soldiers crawled forward while observing the busy situation ahead.
At this moment, the wounded soldiers of the Japanese army no longer groaned.
Because before them, there was already poisonous gas that filled the air and cut off the last breath of these Japanese soldiers.
In the position where the soldiers of the Fourth Army were, a scout smelled something.
The smell was mixed with the fishy smell, which was actually not that obvious, but the scouts felt a very strong sense of discomfort after smelling the smell.
They felt as if something was pressing on their chests, making them unable to breathe.
"Something's wrong. Do you feel a little tight in your chest?"
A Japanese soldier said.
Hearing this, the scout next to him also coughed and said: "No, it's poison gas. Tell the brothers immediately to put on a gas mask."
As he said this, he immediately picked up the gas mask he carried with him and fastened it on his face.
At this time, the sirens were also heard on the battlefield.
A large number of soldiers of the Fourth Army woke up to the sound of sirens. Like other soldiers, they put on their gas masks to resist the poison gas invasion of the Japanese army.
Bai Rihui had just slept for a while when he was woken up by the noise around him.
He opened his eyes, and before he could speak, his guard had already fastened a gas mask directly on his face.
"What?"
Bai Rihui asked next to him.
The soldier immediately said: "Oh no, the little devil on the other side has released poisonous gas. Didn't you smell it?"
Hearing what he said, Bai Rihui felt that there was really a breath lingering on his lips and nose.
That kind of breath was very uncomfortable. He felt a little tight in the chest and short of breath, as if someone had hit his chest with a hammer.
"It's a suffocating poisonous gas."
Bai Rihui said, then shouted loudly, "Tell the brothers to put on gas masks."
"yes!!!"
The entire defensive position of the Fourth Army was boiling. Everyone had woken up from their sleep. No matter how tired they were, they had all put on gas masks.
In front of them, the Japanese soldiers who were still groaning now lost their groaning sounds because they had inhaled a large amount of poisonous gas.
Those wounded Japanese soldiers would not have thought that they would eventually die from the poison gas cast by their own people.
Bai Rihui looked ahead carefully. For him, in the darkness ahead, there must be a large number of Japanese troops approaching.
However, the infrared night vision device they have in front has limited power and cannot be seen too far away.
He can still conclude that the Japanese troops on the opposite side must be waiting for the poison gas to take effect before launching an attack on them.
¡°There seems to be no trace of Japanese troops on the front, or it may be that they have not entered our observation range.¡±
The soldier at the front said.
Bai Rihui immediately took over the infrared night vision device, stared ahead, and said after a long while: "Don't worry, the little devils on the other side will have to wait for us to die before coming back." (Remember the website address: www.hlnovel. com
