The shelling lasted more than ten minutes, covering all the five kilometers outside the camp, and had reached the edge of the woods, on the bank of the Baoqing River.

After the shelling, the Japanese began to build communication trenches, build trenches, build pillboxes. After they had carved out the general shape with their shovels, buckets of water were brought over from the camp, and in a matter of minutes, the trenches under the snow were as solid as steel, and it was impossible for the shaking to collapse unless there was shelling. These trenches were connected a few hundred meters later into a circle of trenches, and not far from the trenches was a bunker made of snow.

With buckets of water poured on them, the trenches and pillboxes became comparable to concrete buildings. In just three or four hours, the trench was rolled out five times with a circle of 500 meters, and it was two kilometers away from the camp.

With the stationing of Japanese troops in pillboxes and trenches, the shelling began again.

In the loud bang, the forest edge was bombarded again.

On the top of the mountain, Dong Ku took all the commanders above the company commander level to lie there, watching the movements of the Japanese army under the mountain. After seeing the shelling, the Japanese continued to dig trenches in the direction of the mountains and forests, while the other directions seemed to have stopped expanding, and no trenches appeared for half an hour.

Dong Ku put away the binoculars, took off the respirator and ordered: "Leave a squad to monitor, and the others go back to the camp to rest, the Japanese army will not be dispatched today, and tomorrow it will rob the trees on the side of the mountain and forest." ”

As Dong Ku and the others descended the mountain, the Japanese army stopped advancing as Dong Ku expected, when the last trench was still a kilometer away from the edge of the forest.

However, this is only the appearance, under the snow shell one or two meters deep, the traffic trench is still digging, obviously, they plan to sneak close to the edge of the forest, and then concentrate on the force to raid and occupy the mountain forest and grab the trees.

On the top of the mountain, a soldier took off his breathing apparatus and asked suspiciously: "Squad leader, you see that the Japanese soldiers in the trenches are still throwing snow outward, it's been an hour, if you dig the trenches, it should be exposed." ”

"yes......"

The Orion squad leader next to him looked at the mountain in confusion: "They won't be digging the passage at the bottom, right?" After speaking, he quickly took off his backpack, put the gun into the holster of the white cloth, pulled the white holster from his neck to cover his mouth and nose, and whispered, "You guys are staring, I'll go around and take a look, I always feel wrong." ”

"Uh-huh!"

The others then stared down the hill.

The hunter went around the back of the mountain for two or three miles, and then pushed his skis all the way down the mountain. When he arrived at the edge of the forest, he put his skis together, and the man lay on them, gently supported them with his hands, and silently slid towards the protruding position of the Japanese position......

"Oh yes! Sure enough, I'm picking the channel!! ”

When the squad leader was more than 500 meters away from the edge of the forest, he heard the movement under the snow not far away, cursed secretly, quickly turned around, slid out of the river on his stomach for two or three thousand meters, stood up and propped up his skis, and disappeared into the mountain forest.

"Pick a hole?" Dong Ku's eyes narrowed when he heard the report. After pondering for a while, he left the camp with a few Oroqen guards and followed the squad leader......

Under the snow, Dong Ku slowly dug forward until he was close to the position of the passage poured out by the Japanese army, touched the ice ballast with his hand, and then turned around and withdrew from the passage with a few people.

More than two hours later, a treetop at the edge of the forest below the mountain swayed, and then slowly disappeared under the snow, and a snow pit appeared in the position just now, like an hourglass, flowing snow particles down the slope; A trace of collapse stretched out thirty or forty meters in the direction of the barracks.

Under the snow not far from the end of the collapse, in a tunnel six or seven meters long and three or four meters wide, the Japanese army was cutting off the big tree that had just been cut down; As the sawing is cut and the rest of the tree is pulled, the tree is slowly broken down and dragged into the tunnel.

Behind him, several Japanese soldiers carried a meter of wood and quickly disappeared into the passage. More Japanese troops were waiting there, waiting to carry the severed trees and branches.

There are four such tunnels, all of which extend to the trees, and the logging begins under the snow.

The snow here is more than five meters thick, and the passage cut out by the Japanese army is roughly triangular, narrow at the top and wide at the bottom. There were fist-sized vents every few meters, so that there was oxygen in the passage for the Japanese soldiers to breathe.

In the passage, the Japanese army continued to carry water forward, and the snow cut down backwards, busy, like ants moving.

A Japanese soldier carrying a bucket of water turned sideways to make way for a Japanese soldier carrying a log when he suddenly heard a sound coming from the ice wall next to him.

"Nani?"

He lowered the bucket and pressed his head to the ice, trying to hear what it was.

Suddenly, the ice exploded, and a fist-sized hole appeared, and a black thing hit the opposite cave wall in a flash.

The soldier was startled, and before he could shout, his eyes widened in fear, and he didn't care about shouting, so he covered his mouth and nose, turned around and squeezed away his companions, and ran back.

As he ran, more Japanese soldiers were terrified, covered their mouths and noses, and ran back. The Japanese troops on the opposite side were also like seeing the devil, so they turned around and rushed in the direction of logging, not caring about any wood or snow.

But they had only run out of the road for a few tens of meters, and the Japanese soldiers rushed to the opposite side, with the same desperate horror in their eyes, and they also covered their mouths and noses.

At this moment, the passage was chaotic, and the Japanese troops were crowded together, and they didn't know which way to run. Behind them, thick smoke quickly filled the air, and in the desperate crowding of the Japanese army, it only took a few seconds to swallow them into the smoke.

Ahem!!

The sound of violent coughing resounded through the cave as the smoke filled the cave, and the flashlight hanging on the cave wall lost its light in the smoke.

A Japanese soldier desperately banged on the cave wall, trying to cut open a hole and escape. Only then did he regret why he had poured so much water into the snow cave and made it so strong.

This is happening in all four passages. The Japanese soldiers who had not entered the passage in the trenches, or who had just squeezed out of the passage, fled in terror near the mouth of the tunnel, and fled far into the trenches or into the passages. Soon after, thick smoke rose from the passage.

From a distance, the snow looks like a warm spring, and the smoke is slowly dispersed in the north wind.

Looking at the Japanese soldiers in the tunnel, one by one snot and tears flowed, scratching in pain, and the severe lack of oxygen made them give up covering their mouths and noses, and in the struggle, they slowly fell down and fell into the grave they dug for themselves.

Soon, the camp received a report that the other party had used poison gas to suffocate the soldiers in the tunnel. Shocked, Iwakoshi hurriedly opened the munitary depot and distributed the gas masks inside to prevent the other party from shelling the camp with artillery.

But he waited for an hour, and when it was almost dark, the other side did not carry out artillery shelling.

Estimating that the poison gas should be dissipated, the Japanese soldiers cautiously marched to the rearmost passage with gas masks to check the situation.

In the tunnel, there are piles of frozen and stiff corpses everywhere, the death is strange, the common characteristics are purple face, pupils are congested, and occasionally there is blood from the mouth and nose, but none of them have the manifestation of poisoning, they are all suffocated to death.

The searching Japanese picked up strange warheads, similar to the shells used in grenadiers, but elongated.

After careful study, it was found that it was a smoky warhead, not a concentrated liquid poison gas.

A Japanese soldier with experience with poison gas bombs had the courage to take off the gas mask that had been blocked by frost and could not breathe, and approached the warhead to smell it, confirming that it was a tear gas bomb, not a poison gas bomb.

"This is the new weapon of Soviet Russia?"

Iwakoshi asked as he looked at the warhead in the soldier's hand.

"Yes! Your Excellency Lieutenant General. After the soldier finished speaking, he added, "This is a gun grenade, and from the shape of the design, it is estimated that it has a longer range than the production of our empire." ”

"Gun grenades? They actually used chemical bombs on gun grenades! ”

This news shocked Iwakoshi Tsuneichi, which was a product of a technique that was higher than that possessed by the Empire. The news is more valuable than the hundreds of soldiers lost.

"Generate electricity! Tell the command the news! ”

Here in Baoqing, the Japanese army is racking their brains for life-sustaining firewood, and the reinforcements on the road are also struggling.

The Japanese troops in the direction of the Qitai River suffered the greatest losses, marching less than 20 kilometers along the way, losing more than 2,000 men, and not even catching the shadow of the other side. It was only after dark, after they had camped, that the real nightmare began.

Finally, they camped in the valley, arranged defenses, and lit fires for warmth, but they were bombarded with overwhelming shelling, and dozens of shells were guaranteed to be ushered in as long as there was fire in the leeward part of the valley several miles long. The caliber of these shells was extremely small, and the radius of destruction did not exceed thirty meters, which was much smaller than the radius of destruction of grenades from grenadiers.

But even so, the number of dead and wounded was quite terrifying, and in just one round, more than 3,000 soldiers were killed or hit by shrapnel. After the attack, there were miserable screams everywhere, and in the dark night, in the sound of ghosts crying and howling, no matter how bold they were, they were terrifying.

What frightened them the most was that these shells were not only prefabricated fragments, but also steel balls, and as long as they exploded, there would be nothing to be lost within 30 meters.

The sentries on the top of the mountain who were in charge of guarding had long been silently sniped, and after the Japanese army reacted and rushed to the top of the mountain, in addition to seeing the corpses of those sentries, there were messy footprints.

Fear, lingering in the hearts of these soldiers, not only did they lose nearly a wing of infantry in a day's battle, but at night, exhausted and frozen, they did not dare to make a fire to keep warm. Although it was only twenty kilometers away from the city, they knew that the way back would not be easier than when they came.

Fortunately, the situation was again increased at the Qitai River, and a bonfire was raised when a brigade rushed to the camp of the previous troops after the explosion.

The situation was similar for the other two routes, which could only travel more than 20 kilometers in a day, and each team lost more than 1,000 men. This was not the biggest loss, and there were not many officers left of the three reinforced brigades, except for the brigade commander. Lieutenant officers are also basically gone. At the end of the day, there were few commanders of the entire team.

They divided their troops into several routes and occupied several hills, but they still couldn't stop the attack. It's just that later they specialized in sniping the officers on the periphery, and the ones who can be left are the generals in the middle team.

In the end, he ordered Harbin, Mudanjiang, and Jiamusi to transfer troops to all move in the direction of Baoqing, and the troops of Qitaihe, Shuangyashan, and Mishan stayed behind with a thousand-man wing, and the rest rushed to reinforce, which led to the origin of the reinforcements on the road to be relieved of the danger.
