After a day of high-intensity fighting, the Xionggu Regiment and the Factory Guard were now like two beasts that had just experienced a fight.
He was quietly licking his wounds, trying every means to regain his strength, and preparing for the next death battle that might come at any time.
The nights during the Anti-Japanese War were not as brightly lit as they were in the 21st century.
Troops like the Guard, which were confronting the enemy on the front line, had to implement strict lighting control, making the starless night look even more bleak and desolate.
No one noticed that a group of Japanese soldiers were lying on the ground and quietly groping upwards.
Each of them holds a wooden stick in his mouth, and all metal objects on his body are wrapped in cloth, for fear of leaking any reflection or even making the slightest sound.
Everyone was concentrating, tensing the muscles of the whole body, and crawling to the top of the mountain little by little with extreme patience and perseverance.
The time they chose is even more subtle, it happens to be between two and three in the morning when a person's spirit is most likely to slack off.
"Click..."
"who?!"
A sudden sound sounded in the middle of the team. It was a Japanese soldier accidentally crushing a dry branch.
All Japanese soldiers immediately pressed their bodies tightly to the ground.
Now that the Eighth Route Sentinel has been alerted, they can only act like an ostrich and pray that the sentry does not discover them.
Perhaps the unreliable Amaterasu finally showed up.
The little sentry looked in their direction for a while and found nothing unusual, so he returned to his original post.
At this time, every one of the Japanese soldiers was covered in cold sweat.
Especially the team leader who led the team this time.
This team of more than 50 people is not a normal establishment at all.
It is a temporary team selected from the best of the less than 1,000 Japanese troops left.
They are all veterans who have been in the army for more than four years and have fought in the Chinese battlefield for more than a year.
It can be said to be the most elite combat force in the entire regiment.
We are now less than 200 meters away from the sentry. If discovered, with the firepower displayed by this group of eight soldiers during the day, they can be beaten into pieces within ten minutes.
Moreover, it is impossible for Kumagai United to organize another team with the same execution ability as them.
But a miracle really happened.
He couldn't think of any other reason why he hadn't been discovered at such a close distance other than luck.
After looking behind them and waving, everyone slowly took out the equipped 99-type gas masks from their waists.
If you understand the structural principles of a gas mask, you will know that it is designed to isolate as much unfiltered air from the outside world as possible.
Therefore, except for the long tube connected to the filter barrel, the entire gas mask must be tightly attached to the skin of the head, without leaving any gaps.
The filter is one-way and can only go in but not out. If you don't want more and more exhaled exhaust gas in the mask, you must put a one-way valve to discharge the exhaled air.
Is this enough?
Of course not enough.
Gas masks are not masks. When they need to be used, it often means the situation is serious.
Therefore, communication has become something that cannot be ignored.
But what is the sound?
It's the vibration of the air.
The filter and waste gas valve are both one-way and are only responsible for the inlet and outlet of air. Who cares whether your air vibrates or not.
So in this case, carrying such a gadget is equivalent to putting your head in a confined space. No one can hear you even if you scream.
So how do you get people to hear what you are saying?
The designer of the gas mask suddenly made a small opening in the mask. This small opening did not contain any one-way valve or glass piece.
Instead, it is sealed with a small plastic sheet, and two metal covers are used to cover it inside and outside to prevent it from being broken.
Because the plastic sheet is moderately soft and hard, it can completely follow the air to produce a small elastic deformation, and the vibration is generated.
Therefore, when a person talks while wearing a gas mask, the sound produced in the mouth causes the air inside the mask to vibrate.
The vibration of the air inside the mask causes the plastic sheet to vibrate.
The plastic sheet drives the outside air to vibrate.
This is equivalent to using such a small plastic piece to achieve vibration transmission without gas exchange.
Doesn’t it feel like a genius?
There seems to be no shortcomings except that the sound will become super weird, right?
Haha, not really.
Otherwise, this Japs team wouldn't have taken out their gas masks and put them on just now.
Don't forget that this plastic sheet doesn't care what you are talking about.
As long as there is gas vibration, it will be transmitted intact.
There are two one-way valves over there.
When the incoming and outgoing air passes through these two things, friction will inevitably occur.
In addition, the gas mask is a confined space and has a bit of an echo effect.
Therefore, the sound of these two frictions will not only be transmitted intact by this plastic piece, but it will even be amplified a little.
So there is the sound of "huh~puff~" that we often hear in film and television works, which can make people feel so oppressive.
This sound, logically speaking, is not very loud.
But don't forget where they are now.
In such a silent late night with no wind for such a month.
The strange breathing sound made by more than 50 people is no different from a tractor in a busy city.
Make it stand out abruptly and attract attention.
So less than half a minute after they all put on gas masks, the village sentry discovered them.
"Bah! Bah! Bah!"
"It's the Japanese who are coming! Shoot the flares quickly!"
"Go bang! Poof!"
The little sentry who finally discovered the enemy fired and shouted immediately.
Not only to kill the enemy, but also to report the news.
However, the bullets he fired in a hurry did not hurt any enemy. Instead, he was shot through the chest by the Japanese veteran who had been staring at him for a long time.
"Hand cannon! Fire!"
"Tum! Tum! Tum!"
"Puff puff!"
A few familiar muffled sounds represented the launch of the grenade.
A few unfamiliar muffled sounds meant that the grenade grenade did not explode at all.
When the belated flares were finally fired into the sky by mortars.
What came into view was almost half of the village shrouded in yellow-brown poisonous smoke.
"Cough cough cough..."
"vomit……"
"Japanese gas bombs, wear a gas mask!"
…
"Xinxi! The commando team succeeded!"
"Artillery squadron! Continue the gas bomb attack!"
"Matsukou Squadron! Attack!"
As soon as the order was given, nearly two hundred Japanese squadrons wearing gas masks and kneeling on one leg, waiting for orders, immediately took action.
This tactic of using poison gas to cover the attack has always been the enemy's strength, and now they are naturally familiar with it.
The Eighth Route Army on the top of the mountain has fallen into chaos, and it is time to give them a fatal blow.
Therefore, Songkou Squadron basically showed the energy of charging and moved forward at full speed.
Seeing that the follow-up troops were following up, the Japanese team leader no longer hid himself.
Now that the follow-up troops are about to arrive, and the enemy in front is in chaos, there is definitely a lot to be done with this group of veterans.
"superior!"
With that said, he inserted his bayonet and rushed out with the other team members.
But if they could rush up so easily, they really wouldn't be factory guards.
After just a few steps after rushing out, someone kicked and broke a thin metal wire.
In an instant, dozens of explosion points exploded on the slope in front of the entire village at the same time.
Each bomb is not big, and if you take a closer look, it should be quite familiar to the Japanese.
Aren't the explosives buried shallowly in the ground their Type 95 grenades?
Such an unscrupulous minelaying method was naturally provided by Zhu Han.
The trip wire is just a few centimeters higher than the ground, which is exactly the height of a person's shoe sole when walking.
The entire process from touching to kicking off the trip wire is completely imperceptible.
Not to mention that the Japanese had never seen this method of laying mines before.
There are dozens of trip wires throughout the minefield, each of which can detonate all grenades.
Therefore, the soldiers never worried that this thing would not be stepped on by the Japanese.
Moreover, there were so many grenades seized that even if the enemy used artillery to clean them up, they would be happy to see the Japanese wasting artillery shells on such meaningless things.
But don't forget, the cast iron projectile of the Japanese grenade has a fragmentation slot.
At this moment, when it exploded, the 48 fragments of the projectile were driven down by the spherical shock wave, and half of them rushed down and pierced into the soil.
The other half was shot in all directions in a hemispherical shape, all heading towards the three directions of the Japanese.
