After Zhang Long confirmed that this place was over and there was no way out, he quickly replenished the grenade, took Li Ruide, and carefully searched back.

Along the way, the tunnel is extremely quiet, the soles of their feet are soft rubber, and they walk very clearly, relying on their sense of hearing to judge the environment, and they dare not be careless.

Halfway through the walk, entering the place where the corpses of the Japanese army were dense, Zhang Long was more careful, and every few steps he took, he had to squat down and listen carefully.

As he was walking, suddenly, a few meters in front of him burst out of flames, and the firelight instantly illuminated the pitch-black tunnel.

Crooked!

Zhang Long flashed, and Li Ruide leaned against the root of the wall, squatting down and aiming at the muzzle there.

But there were only tongues of fire erupting, and a dozen rounds stopped, and the hole was clearly a firing port, and the man was in the wall.

Li Ruide patted Zhang Long behind him and told Zhang Long with this body language that he went to blow up the machine gun, and he flashed it for cover.

Zhang Long grabbed Li Ruide and whispered, "Retreat!" ”

Without the slightest hesitation, Li Ruide stopped moving forward and ran backwards quickly.

Li Ruide left, Zhang Long took out four grenades in a row, pulled out the safety one by one, held four in his hand and knocked them on the wall together, and then threw them to the location of the gunfire by feeling, ran back wildly, and ran to the bend in a few steps, and was immediately caught by Li Ruide, and the two turned back again.

As soon as they crouched down, there was a loud bang, and a scorching wave of heat mixed with debris that I didn't know what it was, swarming their heads and almost losing consciousness.

The shock wave passed, the shock disappeared, but it was half a sound, and Zhang Long and Li Ruide, who were buzzing in their ears, got up from the corner of the wall; Hey, touch back in the dust.

Zhang Long pressed his hand against the wall and found the approximate location by feeling. His hand touched the secret door in the wall. By his hand, he knew that it was a wooden plank, wrapped in cement, which was shattered by a violent explosion and shook open the secret door.

He slowly opened the door with the muzzle of his gun, and the flashlight went on. So he was recruited.

Hey?

The light that went out in an instant still made him see clearly, this was a mechanism, a crooked handle tied to an iron shelf, the space was more than a meter deep, half a meter high, but there was no one to hide.

He ordered uncertainly: "Watch for cover!" ”

After Li Ruide took half a step forward, he turned on the flashlight again.

This time, he saw clearly, it was a dark grid. It's a trap, a rope tied to the trigger of a gun, and the muzzle of the gun is at the crotch of a person, but there is no one at all.

The moment the flashlight turned off, he could see the direction in which the rope was entering, the direction in which they were going back.

He was just about to remind Li Ruide, but Li Ruide whispered: "There is an abnormality in the three meters on the right side of the front!" ”

Zhang Long was clever, and the muzzle of the gun was instantly aimed at the darkness.

Li Ruide cautiously touched it. Then, under the cover of Zhang Long, the flashlight was turned on.

The flashlight lit up. What they saw was a hole hidden in a stone slab shattered by the shock wave, a hole that could crawl over people.

Li Ruide did not hesitate, and at the moment when the flashlight went out, with the light that disappeared, a grenade was thrown in.

The two of them ducked back, and the sound of jingle grenades rolling. With a bang, a ball of fire erupted from the hole.

With experience, both of them saw the pieces of meat mixed in the firelight, and it was obvious that Japanese soldiers had been blown up.

Zhang Long waited for the shock wave to erupt, and rushed to the entrance of the cave with an arrow step. I quickly picked up the backpack and got into it without hesitation.

The body was spread out, he quickly turned on the flashlight, and suddenly the light lit up, a corpse with the upper body shattered, and a corpse with a face full of shrapnel appeared in the dust.

He quickly glanced here, it was a small space, only three or four square meters, and there were four or five teacup-sized holes in the wall, which should be the shooting port. There is a single simple bed in the corner, which seems to be one person on duty and one person sleeping.

Next to the bed, there were grenade boxes and food, and two oil drums pierced by shrapnel, dripping with liquid.

Gasoline!

Zhang Long was taken aback, and then denied this judgment, he didn't smell the smell of oil.

I got up and walked over and sniffed it with my hand, and sure enough, it was water.

The moment he looked beyond the oil drum to look inside, he was startled again and almost turned to flee.

The red-painted bullet told him it was a gas bomb!

Oh yes! Fortunately, there is a bucket in the way, or else, this gas bomb will not be exposed?!

Looking at the two gas bombs intact in shock, Zhang Long quietly wiped the sweat from his forehead. If this leaks, he and Li Ruide will be completely glorious.

"Target clearing, safety!"

Calming down, Zhang Long said as he retreated.

As soon as he came out, he whispered: "Go, we have to leave as soon as possible, put on gas masks, and don't fall in love with war!" ”

"Roger!"

Li Ruide replied in a low voice, and quickly took out his gas mask and put it on.

The two of them simply packed up, carried their bags, stuck to the base of the wall, and quickly ran towards the road they came.

When Zhang Long was running back in the tunnel, a soldier who was lying on his stomach about a kilometer away from the Japanese position suddenly sniffled and said strangely: "Why is it so fragrant?" ”

As he spoke, he looked up and looked around suspiciously, and found that there were all white cloaks and white hats all around, and he couldn't tell who was a woman.

Before he could decide whether to report it, the soldiers near him twitched their noses and looked around, apparently also spotting the scent.

"You smell it too?"

He asked with a whispered tilt of his head.

"Yes, it smells good."

The warrior next to him replied.

"Yes......"

Before he could respond, he suddenly felt a bout of dizziness in his head, and sleepiness hit him.

He endured his sleepiness, grabbed a handful of snow and wiped it on his face, and hurriedly turned on the walkie-talkie when he was sober, and reported the situation to the squad leader.

His squad leader also smelled it and felt sleepy, but he didn't understand why, so he also reported the situation.

The news was passed on layer by layer, and soon reached the division commander who was not in command at the front.

The division commander's name is Pang Qingshui, a soldier under Qu Jungang and a veteran of Pontianak. He received a report that a woman had infiltrated the attacking troops in front, and he did not dare to slack off, so he hurried there.

But after some investigation, except for the fragrance is still the same, and the person is a little drowsy, the woman is not found.

He was just about to sift through all the warriors in this area when one of the warriors suddenly whispered, "The scent is coming from under this stone." ”

Under the stones?

Pang Qingshui climbed to the side of the bow in confusion, and sure enough, the aroma of the stone was much stronger.

"Lift this stone!"

He ordered without hesitation......

Dong Ku and the others were wondering whether they were going to act tonight, although they didn't know what the Huya that had infiltrated the road had gained, but the attacking troops had been lying on the snow for several hours, and if they didn't attack, they had to retreat, or they wouldn't frostbite the soldiers.

At this moment, Qu Jungang suddenly said, "What? Found a vent made of cement? Good! Look don't take action, I'll be there soon. ”

The people in the command headquarters all turned their heads to look at Qu Jungang, waiting for him to explain.

"Captain, the eighteenth division found a fragrance wafting out, and followed the fragrance to find a half-foot square cement mouth, under the stone."

Fragrance?

Liu Zhong, Zuo Boyang, Dong Ku and other people who knew ylang-ylang were stunned for a moment, and then reacted, Zhang Long and they used ylang-ylang.

"Let's go! Check it out! ”

Dong Ku ordered without hesitation.

The group quickly arrived there, and Dong Ku then saw a stone weighing a ton being overturned on the ground, and a boxy, half-foot cement mouth appeared on the black soil without snow.

It's ylang-ylang!

Dong Ku, who was familiar with this smell, naturally couldn't smell it wrong, and he looked at the Japanese position in the distance in confusion, where it was a kilometer away from this vent.

Zuo Boyang squatted down and sniffed, and then said, "Captain, this is the air outlet." ”

"That's right."

Dong Ku looked into the distance and said: "The Japanese army is cunning enough, I am still wondering, whether to use Spitfire to set all the Japanese positions on fire, so that there is no need to destroy their ventilation system, now it seems that the Japanese are very smart, they even make the exhaust outlet so far away, so hidden, I am afraid that the air intake is even more hidden." ”

As soon as his words fell, Liu Zhong took a step back and said, "Okay! Defend on the spot and stand by, I'll send someone to answer! ”

As soon as Dong Ku turned around, Liu Zhong said, "Captain, they came out and used ylang-ylang incense in it. ”

"How's it going?" Dong Ku hurriedly asked.

"There is no cleaning inside, and there are Japanese soldiers hiding in the mezzanine, and they found that it was not good to bring a gas face early, and the ventilation system inside is very complete, the mezzanine is not ventilated, and the amount of drugs is laughing.

"Let's go, let's take a look!"

Dong Ku reached out and took the backpack in No. 5's hand, took the semi-automatic handed by No. 6, and ordered directly.

"Yes!"

Sun Tao and the others all fought with the troops in unison, and they didn't feel that there was anything wrong with them going to the battlefield, they were ordered to heal, and they were all quickly armed, Sun Tao called a helicopter at the same time, and ordered an artillery bombardment around the bunker that was about to go.

Dong Ku and the others did not take a helicopter, but several infantry vehicles drove quickly to the bunker where Zhang Long and them were under artillery fire, and then got out of the car and rushed in.

After Dong Ku arrived, he saw Zhang Long and Li Ruide, who were ragged and covered in blood, and learned about the situation inside after simply helping them deal with their wounds.

The ventilation and power supply are independent, and there is poison gas inside......

This news made Dong Ku stunned.

He knew that the gas mask was not a panacea, and if the oxygen tank was not opened at the first time and the outside breathing channel was closed, the gas mask would be invalid when the concentration of the poison gas reached a certain level, and none of the soldiers who entered the tunnel would want to leave alive, including those Japanese soldiers.

Looking at Zhang Long and the others, they have undergone brutal training, although they are not as good as the special forces of later generations, but they are not much different. Obviously, the interlayer in the tunnel is not easy to deal with, and it is impossible to quickly clean up the Japanese army and prevent the Japanese army from releasing poison gas.
