Kijimagawa looked like he was deranged, clutching the tent of the headquarters with one hand, his whole body shaking violently. His eyes were already firmly attracted by the artillery fire of the front position, and his eyes reflected the fierce fire in the sky.

The fire rose with the wind, plunging all of his carefully placed first line of defense into a sea of fire. His heart also burned little by little with the spread of the sea of fire, collapsed little by little, and finally turned into black powder and scattered in all directions.

"What a bullshit conspiracy, what a genius scheme. It turned out that the plan that took me so long couldn't withstand his cannon fire. Kijimagawa stomped on the ground with a hard kick.

"Also, where did they get their damn artillery, it shouldn't have been there." Kijimagawa is already going berserk.

Before this battle, he arranged everything as delicately as a screenwriter. All the details that could happen, he had to try his best to avoid.

In order to prevent the artillery of the Independent Brigade from coming to Hefei, he deliberately asked the Air Force to bomb the Independent Brigade in turn. Based on his understanding of the Chinese, he believes that the Chinese soldiers are a bunch of old hats, and if they finally have artillery, they will definitely treat it as a treasure, and they will never allow artillery more important than life to be blown up by aircraft.

Therefore, he determined that the independent brigade would definitely be evacuated by the artillery to avoid appearing in this battle and eventually being blown to scrap metal. But now the artillery of the Separate Brigade has reappeared, and it is still bombarding his entire front with overwhelming superiority, what the hell is going on.

There is no artillery in Hefei City, at most some infantry artillery. But those large-caliber mortars are on the first front, and I am afraid that they have long been burning in flames under the repeated bombardment of the independent brigade.

"Gao Dong, what do you want to do?" For the first time, Kijimagawa tasted the pain in his heart, but he forgot about it. Gao Dong's offensive methods were a bit similar to those of the Japanese, and before each attack, they used artillery to clear the way.

No matter how crazy the Mudaochuan in Hefei City is, the artillery outside the city still continues happily. The reconnaissance unit has given the coordinates to the artillery unit, and is constantly sending in changed coordinates.

The artillerymen simply filled the chamber with a bullet, and then easily pulled down the firing rope, and a single shell would fall towards the devil's position with a huge force that could bombard and kill more than a dozen people.

And the first front of the devils, under the repeated bombardment of the artillery of the independent brigade, the devils who did not have anti-bombing trenches at all suffered heavy casualties.

When the Japanese army built this first front, they did not take into account that the independent brigade would also bombard with artillery, so in order to save time, they only built relatively strong anti-infantry trenches and did not dig anti-artillery holes.

Under the dual threat of explosion and fire, many devils abandoned their positions and ran frantically towards Hefei City behind them. The first front of the devils was bombarded by the independent brigade in turn, and after an hour it was already in name only.

Gao Dong was still standing on top of Gao Dong, monitoring every move of the Japanese position. When he saw a large number of Japanese troops fleeing from the first front, the corners of his mouth finally smiled.

"Captain, what's next?" Lin Fan asked.

"Order the troops to carry out the excavation operation!" Gao Dong said.

"Tunneling? Where are you going to dig the tunnel? Lin Fan asked after a pause.

"Dig the tunnel under the city of Hefei!" Gao Dong narrowed his eyes: "Didn't you see that the devils all took surprisingly consistent routes when they escaped?" What time is it now, it's a time of life and death. They can still think of choosing a route and escape in a straight line. Even the devils who are far away have to risk their lives to cross the position of a sea of fire, and make a detour to this straight line to escape. ”

Gao Dong turned his head and stared at Lin Fan tightly: "What does this mean?" This shows that after the first front, there is simply a death zone, a death zone specially prepared for us. Whatever is out there, we must not rush into it lightly. Order the troops to dig tunnels, I'm going to surprise the devils! ”

"Understood!" Lin Fan admired Gao Dong's observation ability, and he could still see this kind of detail in this situation, which fully explained how detailed his heart was.

Lin Fan conveyed the order to Hu Xinghan, who immediately dispatched troops to start the excavation operation. The devils in Hefei City are being attracted all the attention by the artillery fire, and the devils on the first front are either busy fleeing for their lives or struggling in the sea of fire.

And the devils in the city are all devoted to the upcoming attack of the independent brigade, how can they care about what the independent brigade outside the city is going to do at the moment.

Even Kishimagawa didn't have this mind, he couldn't see through Gao Dong's opponent at the moment. This guy didn't play according to the routine at all, and Kijimagawa, who was originally the screenwriter of this battle, suddenly felt that he had become an actor, or an unimportant actor who was put wherever Gao Dong wanted.

The independent brigade was organized into three parts, and in order not to arouse the suspicion of the enemy, the two parts continued to hold their posts, and the remaining part began to dig from behind the city of Hefei.

The excavation troops are equipped with sappers, and with these sappers present, it is equivalent to giving a preventive shot to the entire excavation work. It can effectively prevent collapse and other conditions in the tunneling, and can also solve many difficulties in the tunneling.

Fortunately, each of the soldiers of the Separate Brigade had a basis for digging trenches, which was also one of the training subjects of the Separate Brigade. On the battlefield where every second is in the running, being able to quickly dig trenches or individual bunkers is the basis for saving lives. Therefore, an important subject of the independent brigade in peacetime is digging trenches, which tests not only a soldier's physical strength, but also his willpower.

But relying only on the soldiers of the Separate Brigade, it is clear that the speed of the excavation is not fast. Gao Dong's meaning is to dig tunnels under Hefei City overnight and pass through many obstacles.

So Hu Xinghan transferred two-thirds of the captured devils to participate in the excavation work, and the remaining one-third continued to be used as human targets to prevent the devil air force from bombing.

Under the threat of the guns of the black holes, these captive devils had no choice but to dig hard in the tunnels and fill in the earth and transport them out. They knew that they were helping the Chinese to slaughter their compatriots, but under the threat of gunpoint, they had no chance to resist.

The devils finally felt the feelings of the Chinese people who were forced to do things against their will under his gun. That kind of humiliation is unwilling to pour into their hearts like a tide.

Wood is constantly being transported from all over the place and sent into the tunnel to support and fix the tunnel and prevent it from collapsing. The darkness of the night was dusty, and the speed of the excavation was very fast, and an hour later it had already advanced from the position of the independent brigade to the first line of battle where the devils were being bombed.

Feeling the loud rumbling overhead and the tremor of the earthquake, the soldiers of the independent brigade dug even harder. The feeling of the invaders being slaughtered right above their heads is a thrill that only those who have had their homes destroyed can experience.

Two hours later, the tunnel had almost dug under the city of Hefei, and the distance was no more than a kilometer. The artillery fire was still rumbling and continuing, and in order to cover up the fact that the independent brigade was digging, the artillery bombardment target was also advancing in the direction of Hefei from the first line of battle of the devils.

The tunnels that were being excavated were safely covered, and the devils in the city trembled under the artillery fire, and some even had the idea of escaping, and no one realized that a very dangerous tunnel was approaching them.

Mu Daochuan stood on the city wall of Hefei with a pair of blood-red eyes, looked at the artillery fire that was getting closer and closer, and roared angrily: "Everyone give me access to the second line of defense, quickly!" ”

"But Your Excellency, the artillery fire of the Independent Brigade is getting closer and closer. If we had stayed in the city, wouldn't we have suffered heavy casualties? A subordinate reminded loudly.

"Are we the Imperial Army of the Great Japanese Empire still afraid of death?" Kijimagawa turned around and slapped his subordinates in the face, then turned his head and smiled grimly: "As long as the independent brigade dares to attack, they will taste the gift I left for them." It was almost impossible for them to reach the city safely. Even if they get here, it will be the end of the crossbow, and our heavy machine guns will be condescending and will give them a sniper kill of a lifetime! ”

All the remaining soldiers of the Kijima Wing were transferred to the city wall, and the more than 2,000 puppet troops were also driven to the city by the Japanese army. However, these people are not reliable at all, they are at most second-rate troops in the puppet army, and they have to defect to the Japanese. If there was any danger, they would be the first to flee.

All kinds of heavy weapons were erected on the top of the city, and there were more than fifty heavy machine guns alone, which was almost a huge fortune for a wing.

Light machine guns, mortars and other melee weapons were also mounted on the top of the city. Grenades were placed in front of the soldiers in rows, and every devil was anxiously waiting. They weren't as calm as Kijimagawa, and the thick aura of death that came with the artillery fire made their whole bodies tremble.

Another hour later, Hu Xinghan hurriedly ran to Gao Dong's side, straightened up and reported: "Captain, the excavation work has been completed." In the rear of Hefei City, a passage was opened in the weak place of the Japanese defense, only eighty meters from the city wall. ”

"Good!" Gao Dong's eyes lit up, and his fists clenched: "Let the troops be ready and ready, and when all of our Heavenly Wolf Commandos enter, you will enter immediately." ”

"Let the artillery continue to bombard until dawn!" Gao Dong had a smile on the corner of his mouth: "If the little devils suddenly saw that their city was full of people at dawn, would they fall down from the city wall in fright?" ”

Everything was carried out in accordance with Gao Dong's orders, and the independent brigade urgently moved to the rear of Hefei City. With the double cover of darkness and artillery fire, even if they move under the noses of devils, there is no possibility of being discovered.

Gao Dong led the Sky Wolf Commando to stand at the entrance of the passage, looking at the tunnel that was still emitting wisps of smoke and dust, and smiled slightly at the corner of his mouth: "Su Rou, I'm here to save you." ”
