At this time, on top of several remaining high-rise buildings on Ping'an Street, soldiers equipped with small catapults were adjusting the angle of the catapults.

Their catapults are all gifted by the system, a total of ten, and two people can move.

Yesterday, Qin Chuan conducted experiments on these catapults and found that these catapults could throw a two-kilogram fuel bottle to a distance of about 150 meters.

Such a distance is already very close compared to grenadiers and mortars, and if it is a field battle, it is basically useless. But in this kind of street fighting, which is mostly hand-to-hand, this catapult has just the right place.

Guo Xisheng, the leader of the catapult team, waved the order flag in his hand at this time and shouted: "Catapult ready!!" Load!! ’

With his order, the soldiers on the roof of the building pulled their springs to the end. The lit Molotov cocktail was then stuffed directly into the launcher.

Through the ejection of the spring, the catapult will catapult these bottles, filled with alcohol and napalm, to the target area.

"Launch!!" Guo Xisheng shouted, and the order flag in his hand was directly chopped down.

“DuangDuangDuang！！！”

A neat spring ejection sound directly launched the Molotov cocktail inside the launch canister.

These Molotov cocktails contain two liters of napalm and alcohol, which, when they hit the ground, will break with the glass bottles, causing damage to an area four meters in diameter.

The first round of ten incendiary bombs was fired directly at the heads of the Japanese soldiers who were still there at this time.

Many of them were still cautiously looking down at their feet, but they didn't expect the enemy's attack to fall from the sky at this time.

"Smack!! Bang!! ”

After the glass bottle hits the ground, it will break directly. The burning alcohol and napalm spread rapidly to the glass bottle as soon as it broke.

A few unlucky Japanese soldiers were immediately contaminated by the flames that sputtered out, and turned into burning men, rolling wildly on the ground and screaming.

If it is contaminated with burning alcohol, it is actually relatively lucky, and the flames on your body can be extinguished by rolling and slapping. As long as it's not all set on fire, there won't be much of a problem.

But the Japanese soldiers who were attached to the burning napalm were obviously not so lucky.

Napalm, most of which is made up of colloidal gasoline. The gasoline was developed by a group of chemists at Harvard University and is mainly a mixture of aluminum salts of naphthenic hydrocarbons and palmitic acid, which is gelatinized by the addition of combustible substances.

A Chinese doctor who was providing humanitarian aid in war-torn areas of Africa once described the following tragic images after the napalm exploded.

"After the napalm explodes, it splashes on people like lard paste, sticky and burn-resistant. If a person uses his hand to slap it, it will make the flame bigger. If it is rolling on the ground, the person next to you should stay away from the person on fire, otherwise it is very likely that they will be injured by the burning oil that is thrown out, resulting in secondary injury. ”

In addition, because napalm is added with a lot of chemical accelerants, after burning on the surface of the human body, a large amount of highly toxic chemicals will be left. Through the open window of the burn wound, the bloodstream enters and causes the injured person's blood to be poisoned, leaving him or her to die in agony.

But Qin Chuan thinks that this kind of inhumane weapon is very suitable to deal with these beast-like Japanese troops.

I saw that at this time, many of the Japanese soldiers who were contaminated with napalm were constantly slapping with their hands. As a result, the flames only became bigger and bigger, and some people even had their palms stained with burning gasoline blocks, and their bodies rolled on the ground.

Some Japanese soldiers next to him wanted to help their comrades, but many of them were stuck to their bodies by the burning oil thrown out, making them victims of napalm.

"Second round!! Load!! Guo Xisheng waved the flag in his hand and shouted.

With the wave of the command flag in his hand, the soldiers immediately fired another round of incendiary bombs at the Japanese army.

"Boom!!"

When these Molotov cocktails hit the ground, they immediately set an area on fire. Among them was a Molotov cocktail, which smashed directly on top of the Japanese tank.

The Molotov cocktail that smashed on the top of the Japanese tank exploded on the roof of the tank, and in a blink of an eye, it flowed through the gap in the roof of the Japanese tank into the cockpit of the Japanese tank.

The next moment, a Japanese driver, whose body was stained with flames, screamed and opened the lid of the tank, jumped out of it, and then rolled on the ground.

Shiro Denpei saw these scenes in his eyes, but he knew that his troops could no longer retreat. Such casualties have already been taken, and if they retreat at this time, they will be in vain.

"Keep going, the wounded back back!!" Shiro Chuan yelled inside the tank, urging his soldiers to move on.

Those Japanese soldiers with terrible willpower were already red-eyed at this time and began to rush forward. And the artillery and heavy machine guns on the Japanese tanks roared even more fiercely, used to suppress Ping'an Street.

"Look for the location of enemy launchers, tank guns ready to bombard enemy positions." Shiro Denhei shouted loudly.

The observers in the Japanese tanks immediately began to guess their approximate location through the orbits launched by the Molotov cocktails.

"Twelve o'clock defensive line, eleven o'clock direction, two enemy launcher positions." The Japanese observers quickly reported the position of several launchers.

"Adjust the shooting angle!! Bombard the enemy's launch positions! Chuan Heishiro roared angrily, and several tanks under his command immediately turned the turret slowly.

Seeing the Japanese tank guns and turning the turret to this side, Guo Xisheng immediately said: "Brothers, quickly retreat!" So saying, he picked up a box of Molotov cocktails and took the lead and ran downstairs.

The other soldiers also picked up their launchers and Molotov cocktails and ran downstairs.

They had just run downstairs when they heard a loud noise coming from overhead.

The Japanese 30-mm shells directly collapsed a corner of the roof. The flying masonry and dust were flying, and if they retreated a little later, they would probably be blown away by the shells of the direct Japanese army.

The launcher position here was suppressed by the Japanese artillery, and the speed of the Japanese advance suddenly became faster.
