After being confirmed by the spearheads on the rooftops on both sides of the street, the forward squad of Yamada's squadron entered the street first, and because there were two armored vehicles in hand, Yamada Koji did not show too much caution. After a tentative shelling with mortars, more than 200 soldiers of Yamada's squadron finally poured into the streets, and the Japanese soldiers searched the houses on both sides of the street while guarding the street entrance on the other side.

Seeing that the Japanese soldiers were getting closer and closer, Cui Xiaodong, who pretended to flee from the rout, and his soldiers were ready to shoot at any time, but they didn't see the signal from Qin Feng for a long time. Through the crack in the door of the store, Qin Feng, who watched the Japanese army's every move, did not move at all, the detonator was next to Qin Feng, as long as he pressed the handle of the detonator, everything Qin Feng arranged would immediately see the effect.

Success or failure is only between the first line, but Qin Feng is a little afraid to explode, dust explosion is like a fantasy for people in this era. But for Qin Feng, who came from the later world, it was not a mysterious matter. Solid matter that is broken into fine particles is called dust, and when the solid matter is crushed into dust, its combustion characteristics change greatly. What turned out to be a non-combustible substance may become a combustible substance, and a non-combustible substance may become a flammable substance, and an explosion may occur under certain conditions.

Dust becomes an "explosive" because it has a large surface area. Compared with bulk substances, dust is more chemically active, has a larger area of contact with air, adsorbs more oxygen molecules, and has a faster oxidative exothermic process. When the conditions are right, if one of these grains of dust is ignited by fire, a chain reaction occurs like an atomic bomb, and an explosion occurs.

In later generations, the news of dust explosions in flour mills is no longer a strange thing, and flour explosions should be said to be a very representative affair in dust explosions. When a large amount of flour is suspended in the air and reaches a very high concentration, such as 9.7g of flour per cubic meter of air, once it encounters a flame, spark, electric arc or the right temperature, it will instantly burn and form a violent explosion, which is no less powerful than a bomb.

The more than 200 soldiers of Yamada's squadron marched cautiously to normal speed at the beginning, and it was not long before they reached the middle of the street, where Qin Feng ordered to dig a pit and fill in the flour. Qin Feng in the shop immediately handed the detonator beside him to Liu Dazhuang, but he picked up the rifle himself, "After a while, I'll shoot their sharpshooters first, and when you see me finish shooting the second bullet bridge, press the detonator." ”

Liu Dazhuang wanted to nod, but he didn't know that Qin Feng didn't give him a chance to nod at all, and as soon as he took over the detonator, Qin Feng had already fired the first bullet here. "Bang" a gunshot, a Japanese soldier walking in the middle of the street fell down, before the other Japanese soldiers reacted, Qin Feng's second bullet had already arrived, and the flag soldier with a plaster flag on the "poof" rifle also fell in the middle of the street.

Liu Dazhuang had already seen Qin Feng's marksmanship on the roof, and in the blink of an eye, Qin Feng had already shot out the five bullets of the first bullet bridge, and seeing Qin Feng take the other rifle handed by Da Niu, Liu Dazhuang immediately reached out and grabbed the handle of the detonator, waiting to press the handle down at any time. Liu Dazhuang had seen Qin Feng's method of using two rifles to shoot in turn, and he was no longer surprised, but the other defeated soldiers in their hidden shop were all staring at each other.

Ten shots, Qin Feng only fired ten bullets, and ten Japanese soldiers had already been shot and fell on the street, a distance of 200 meters, for Qin Feng, it was as simple as eating and drinking. The soldiers of the Yamada squadron lowered their bodies and prepared to shoot back, but at this moment, Liu Dazhuang, who saw Qin Feng shoot out the second bullet bridge, had already pressed the handle of the detonator fiercely, and there was a muffled sound of "boom", "boom", "boom", "boom", and a column of smoke rose on both sides of the street.

"Hidden, hidden." The officers and veterans of Yamada's squadron screamed, and the soldiers scattered and fell to their stomachs. It's just that to the surprise of these Japanese soldiers, the sudden explosions on both sides of the street did not hurt anyone, but with the floating soil rose a large puff of white dust, "Anti-poison, fast anti-poison, damn the people of China actually used biological and chemical weapons." Amid the curses of the angry officers and veterans, the soldiers of Yamada's squadron kept cursing while wearing gas masks.

A Japanese soldier with his head covered in white powder subconsciously reached out and wiped it on his face, and then shouted, "It's flour, these are flour." "Ah, it's all flour, don't the soldiers of China have weapons? Did they expect to throw flour to stop the advance of the Japanese army? More and more Yamada Squadron soldiers found that the white powder on their bodies was flour, so the Japanese soldiers who had already put on the gas protection area took off their gas masks and cursed the damned Shina skirmishers again and again.

Qin Feng in the shop pressed the handle of another detonator, and several other explosion points arranged on both sides of the street rang out, and the flour bags covered by the explosives exploded, bursting out a large amount of flour again. "Tom" Da Niu Han smiled and stuck the grenadier out of the window of the shop, and fired a grenade into the middle of the street with the grenadier, "booming" a fireball on the dusty street. Immediately after that, the middle of the street where Yamada's squadron was located seemed to suddenly stand still, and the dust-filled air contracted violently, and with a loud "boom", the air began to become hot and the earth began to tremble.

There was a loud bang like an earth-shattering bang, and the scorching heat in the dazzling fire swept the mud and sand and tore the entire Japanese soldiers into the air...... The entire street was destroyed by the explosion and disappeared, large chunks of dirt and flames were thrown into the sky for dozens of meters, the dust that covered the sky made people want to cough, and the plugged ears were buzzing, and they could only hear their own heartbeat. The explosion had stopped, but there was still a roar in the ears, for nothing could be seen in the thick dust, and everyone was choking on the scorching air and coughing.

"Boom" "Boom" ,,,, explosion began again, and it was the explosion of the ammunition carried by Yamada's squadron, and the ammunition of the martyrdom covered the area again. The detonation of bullets, grenades, and shells once again brought the survivors of Yamada's squadron a gift of death. "Boom! Boom, boom...... The remnants of the Japanese army were all covered in smoke and dust in an instant, and the human body that was blown up in the air and torn into several pieces could be seen in the sudden flash of the explosion......

Rumble...... It seemed that the whole earth trembled, and Hiroji Yamada, who was supervising the battle in the back, was shaken from the ground more than a meter high by the huge blasting force and the armored car under him, even so, Yamada's nose was bleeding, and he was affected by being so far away, not to mention the other Japanese soldiers in the center of the explosion. The shock wave of the explosion intertwined, and the flying debris directly tore some of the hapless Japanese soldiers behind them to shreds. How long did the explosion last? A few minutes or half a century? Hiroji Yamada didn't know, in the confusion, in the hot pain all over his body, he gradually came to his senses and knew that the explosion had stopped.
