In the north of Tengxian County, the fortifications of the Dragon's Tooth Task Force were built on the basis of the city wall, and the communication trenches were dug all the way to the city gate, connecting the ring fortifications outside the city with the city wall, which could be attacked, retreated, and defended.

Qiao Youhua led most of the officers and soldiers of the Dragon's Tooth Task Force into the ring fortifications outside the city along the communication trenches, and joined up with the small group of troops that had been guarding the north of the city before, and they were all in place and ready for battle.

"How's it going?" Qiao Youhua came to Jiang Haidong, who came before him, and asked.

"The devil striker has a brigade, thousands of people, and it has been almost twenty minutes, it's strange, they didn't attack us, and I don't know what they were waiting for." Jiang Haidong replied with his Type 88 sniper rifle on his back and an imported German Mauser rifle in his hand.

Qiao Youhua raised the binoculars and observed, but he didn't see any clues, and was about to say, if the enemy doesn't move, I won't move.

Suddenly, there was a deafening roar of engines in the distant sky, and it was extremely fast from far and near.

Qiao Youhua's face changed greatly, he glanced at Jiang Haidong, and hurriedly raised the telescope again and looked into the distance.

This time, he found the target, it was about four or five planes, and the screeching engine roar was from them, and it was definitely not the Chinese air force that flew at this time, because the air force of the Nationalist government was almost completely lost after the defense of Nanjing.

Now the only remaining forces have been transferred to Wuhan and Chongqing, and if there are planes flying over the East China battlefield, it must be Japanese planes.

At this moment, Qiao Youhua finally understood why the little devil's striker was not in a hurry to attack.

Because they were waiting for the arrival of their land-based aviation, in this lack of air defense, Japanese planes could gallop and dive, raining down waves of bullets and bombs on the heads of any Chinese defender on the Chinese battlefield.

Four Japanese Type 92 land-based fighters and one Type 95 reconnaissance plane roared in a flying formation, and with that reconnaissance plane as the lead, they began to dive towards the north of Tengxian County.

"Pay attention to concealment, air defense!" Qiao Youhua immediately ran along the trench with his waist bent, and reminded loudly that although the Dragon Tooth Task Force had transformed into an elite army, it had not yet saluted the exchange of fire with the devil plane, and it could be said that there was a blank in the air defense.

The officers and soldiers also confirmed that they lacked sufficient awareness of the threat of air raids, and when they heard the sound of planes flying, they even looked up curiously, until Qiao Youhua's mournful voice resounded throughout the trenches, and these elite soldiers fell down one after another.

"Dada...... Whoosh ...... Bang bang bang ......" The five Japanese fighters began to dive and strafe, and the machine guns and on-board machine guns began to roar.

Dense in the air like a chain of fire, whipped on the position of the officers and soldiers of the dragon's teeth, the construction of the debris splashed, smoke and dust everywhere.

Although the speed of the Japanese planes at this time could not be compared with those modern fighters with supersonic speed in later generations, it was also very fast to the naked eye, with a speed of more than 200 per hour.

Then quickly soar up and pull up, make a U-turn and turn.

Qiao Youhua yelled at Jiang Haidong: "Haidong, bring your 88 sniper to me for use!" Two more Heavy follow me up the walls! ”

At this time, in the distant sky, two Japanese bombers emerged from the clouds and flew towards the north of Tengxian County.

Jiang Haidong immediately threw the Type 88 sniper rifle on his back to Qiao Youhua: "There are bullets in it, full warehouse!" ”

Immediately, he took a Czech light machine gun from a machine gunner, pulled the bolt, and followed Qiao Youhua along the traffic trench towards the city with another machine gunner.

......Two Japanese bombers flew over the north of the city and began to bomb them, and one after another they began to fall vertically from under the belly of the Japanese planes in the form of free fall.

Let out that creepy piercing scream.

"Boom, boom, boom!!" A louder explosion than the Dragon's Tooth officers had ever seen before landed on the defensive positions north of the city.

For a moment, the officers and soldiers of the Dragon's Tooth hiding in the trenches only felt that the ground was shaking, and their eardrums were shaken by the huge explosion sound, buzzing, as if they were already deaf.

Qiao Youhua and the three of them had already entered the city, climbed to the top of the city, and as soon as they appeared, they noticed a wave of heat coming from outside the city, almost blowing them away.

Looking outside the city, I saw that the field defense position outside the city was already a sea of fire, and several violent explosions set off monstrous fires and smoke, almost enveloping the entire outside of the city.

At the same time, a few miles away, the Japanese army was on a makeshift sortie position.

A Japanese captain was also watching this scene with a telescope, and when he saw that the position of the Chinese Army outside the city had fallen into a sea of fire, he couldn't help but laugh proudly.

"Hahaha! Yo Xi, the air force of our Imperial Japanese Army is the most powerful air force in the world, and under their bombardment, these despicable Chinese pigs are absolutely dead! ”

The Japanese bombing continued, and the five Japanese fighters before also turned around and resumed their dive strafing.

The Japanese bombers flew at a very high altitude, and even the Type 88 sniper rifle, a cross-era weapon with a huge range, could hardly hit, and even if it did, it lost its penetrating power.

Therefore, Qiao Youhua planned to fight the five Japanese fighters and reconnaissance planes that were diving and strafing at ultra-low altitudes.

The devil pilots all bullied the Chinese army for its backward equipment, no air defense force, let alone air defense weapons, so the flight altitude was very low, and it was rampant.

This kind of distance can be hit even by ordinary 38 big covers, let alone the Type 88 sniper rifle with a high-precision magnification telescope.

Of course, who can reach the range of the 38 big cover, and whether or not they can hit a medium-to-high-speed flying plane, then it depends on one's marksmanship, which is 100 times more difficult than hitting a live target 200 meters away.

Qiao Youhua stood on the battlement wall, raised Jiang Haidong's Type 88 sniper rifle, held his breath, and began to aim at the Japanese Type 95 reconnaissance plane flying in the front.

Quietly calculating the wind speed, the flight speed of the Japanese plane, and the advance of the bullet and the flight trajectory, Qiao Youhua decisively pulled the trigger.

"Bang!" With a gunshot rang out, an armor-piercing bullet was fired out of the Type 88 sniper rifle in an instant, accurately hitting the fuel tank of the Japanese Type 95 reconnaissance plane.

At this time, the protective armor of the Japanese fighters was negligible, just a thin layer of iron, and any bullet could definitely penetrate as long as it hit it within the effective range.

The bullet fired by the 88 sniper rifle instantly pierced the bottom of the fuel tank, and the moment it pierced the thin layer of protective armor, the high heat generated ignited the aviation gasoline inside.

The fuel tank of the Type 95 reconnaissance plane caught fire in an instant, and the devil pilot was taken aback and hurriedly pulled the plane up, but it was too late.
