Shells were constantly smashed into the trenches, blowing up the fighters inside.

Under the light of the fire, the lieutenant could see clearly.

A pair of eyes immediately became hot, and without thinking much about it, he continued to order: "The shelling is useful, the artillery on duty continues to shoot, and all the Eighth Route Army hiding inside is killed." ”

"Stop shelling......" ordered the captain who rushed over when he heard the sound of artillery.

By the time the smoke from the shells cleared, the shelling area had been blown to pieces, and the consumption that had not yet taken shape had been blown out of several gaps.

But after searching the entire area, the captain only saw three corpses of the Eighth Route Army.

The anger came out as soon as he saw the lieutenant on duty and scolded.

"Eight Grid Yalu, will you fight or not, only a few Eighth Route Army will use mortars, do you know how many shells the artillery squad fired just now?"

"Each cannon fired nearly thirty rounds, and the four guns added up to more than a hundred shells."

The lieutenant hesitated for a moment and defended: "The commander is angry, and the lowly has tried to strafe with a heavy machine gun, but to no avail. ”

"If the Eighth Route Army had built an offensive position there, their heavy machine gun fire could directly hit the city and threaten the safety of the garrison at the city head, so the humble duty ordered the artillery to open fire to prevent the Eighth Route Army from digging trenches there."

The captain continued to scold: "Bomb up, but you used too many shells." ”

"At yesterday's meeting, the wing commander repeatedly explained: We will not have any foreign aid after we are trapped in Laiyuan City, and the reserve ammunition will be one less if it is fired, so the troops must save ammunition in the next battle, and they can no longer squander it as before."

"According to your style of play, more than 100 shells will be consumed for more than a dozen Eighth Route Army, and the more than 3,000 mortar shells hoarded in the entire county will be used up in a month at most, and the mortars in our hands will become scrap metal at that time.

The lieutenant could not find any other reason to justify it, so he could only keep his head down and not say a word.

"Sir, the Eighth Route Army in the trenches hasn't been killed yet, and they're starting to dig again." A second lieutenant next to him suddenly shouted.

In the trenches that had not yet been connected, the captain only saw shovels of dirt being thrown out and piled up on the side near Laiyuan City.

swept over at a glance, and the trench that stretched for nearly 100 meters could not see the figure of the Eighth Route Army, and not even a head was exposed.

"Eight Tooth Road!" The captain couldn't hold back and scolded.

Facing the Eighth Route Army hiding in the trenches, he couldn't think of any other way to kill them except mortars.

But judging from the shelling just now, the effect was not very good, and more than 100 shells only killed a few Eighth Route Army, which can be described as a waste of shells.

Thinking of the Wing Commander's order to conserve ammunition, the Captain decisively pressed down the order to continue firing the artillery.

Then he commanded in a deep voice: "Leave them alone." ”

"If the Eighth Route Army is determined to dig trenches there, we will not be able to stop all the shells in stock, and the Eighth Route Army that will be destroyed is still very limited, and the gains outweigh the losses."

"Take 10,000 steps back, even if the Eighth Route Army builds the trenches, the impact on us will be very limited."

"It is impossible for their flying thunder guns to throw explosive packs on the city from more than 200 meters away, and ordinary mortars have limited lethality, and they cannot destroy our city fortifications."

"As long as everyone hides well in the fortifications, there is no problem with safety."

At one o'clock in the morning, under the gaze of hundreds of pairs of eyes, the trench was finally dug.

The captain first saw a ball of flame erupt from the trench, and then heard an explosion of "boom.......

"It's the Flying Thunder Cannon...... the captain shouted, and then a sneer flashed across the corner of his mouth as he looked out of the city.

He was very confident in the judgment of his superiors, and at a distance of more than 200 meters, it was impossible for the flying thunder cannon to throw the explosive package on the top of the city.

"Boom ......"

Sure enough, under the watchful eyes of the captain, the explosive bag the size of a millstone rolled and smashed on the ground more than twenty meters away from the city wall and exploded.

The flames flew and the smoke rose into the air, and the blown up earth flew everywhere like scattered flowers, and some clods of earth flew directly to the city.

The sneer on the captain's face became even stronger: "As I said just now, the flying thunder cannon is definitely not a threat to our safety more than 200 meters away, except for wasting the explosive pack, listening to a sound, it is useless." ”

"Everyone has entered the fortifications and is hidden, and after the flying thunder cannon is ineffective, the Eighth Route Army will most likely continue to attack us with mortars."

As soon as he finished saying "boom, boom, boom......" four shells smashed over.

The captain was right, but he couldn't laugh.

At the moment when the shells exploded at the head of the city, the sound of heavy machine gun fire rang out from the trenches more than 200 meters away, and judging from the sound and firelight, the Eighth Route Army dispatched at least six of them.

Bullets hit the masonry battlements, sparks flew everywhere, and rubble flew everywhere, which looked particularly scary.

"Sir, there is the Eighth Route Army carrying explosives bags and rushing towards the city wall!" A soldier next to him shouted.

The captain was frightened by the scene outside the city, and several Eighth Route Army troops crossed the trenches and approached the city wall like monkeys.

Although only a vague figure could be seen, the bulging explosives bag on his back was still clearly visible.

"What does the Eighth Route Army want to do? Could it be that they plan to attack Laiyuan City directly and blow up the city walls with explosives packs? The captain shouted.

Then he ordered: "No matter what the purpose of the Eighth Route Army is?" They must not be allowed to attack the troops close to the walls. ”

"The troops will fight back immediately and kill them."

"Mortar fire, destroying the heavy machine gun fire point of the Eighth Route Army......"

To the north of Laiyuan City, the puppet army defending the city also heard some strange noises.

After three flares in a row, they finally knew what was wrong.

Nearly 400 meters away from the city wall, the Eighth Route Army dug three trenches at the same time.

Each section was less than thirty meters long, and it did not continue to be lengthened, but the earth was constantly being dug out of the trenches.

"Can anyone tell me what the Eighth Route Army is doing there?" The captain on duty exclaimed with a puzzled expression.

After a long time, a lieutenant reported: "Sir, will the Eighth Route Army dig tunnels again, all the way to the foot of the city wall, and then use explosives to blow up our city fortifications." ”

"I've heard of this style of play before."

"The Eighth Route Army in Jizhong often used this method of play to attack the strongholds and artillery towers of the imperial army. Dig the tunnel directly into the turret and blow it up with a dynamite bag! ”

"Nani?" The captain's brow immediately furrowed, and the furrows deepened.

If that's the case, then it's a big problem.

After staring at the trench for an hour, the trench still did not grow, but the excavated earth not only did not decrease, but became more and more, and it was almost piled up a wall of earth near the county seat.

Cold sweat began to break out on the captain's forehead, and he shouted with a calm face: "The Eighth Route Army must be digging tunnels, if they are dug up, they can send explosives to the foot of the city wall through the tunnels, so that all of us will be wiped out with the city walls, and they must not be allowed to succeed in their plot."

The lieutenant who had just answered the tunnel asked, "But sir, they are underground, we are on the ground, and we don't even know which direction the tunnel is going in, where it is, how to stop it." ”

"Also, as long as they dig deep enough in the tunnel, the aerial bombs dropped by the planes won't necessarily destroy it."

"The imperial army in Jizhong generally dug a blockade ditch deeply, or dug a well in the stronghold, judged the specific location of the tunnel by listening to the sound, and then dug the tunnel with the Eighth Route Army and blew it up. But Laiyuan City was so big that it was almost impossible to use the same method to stop them from digging tunnels to the foot of the city walls. ”
