A magazine of 30,000 rounds, you call it Hanyang

When the brightly colored smoke rose, Zheng Kaixuan realized that his judgment was correct.

"Brother Kaixuan, this is what a poison gas bomb looks like. It looks so colorful, it's quite fancy."

"Brother Kaixuan, well done! The Japs are playing with fire and getting burned. They didn't expect they would get burned by the poison gas bombs. They deserve it! Hahahaha!"

While in mid-air, Li Yunlong saw the thick smoke billowing from the Japanese position and was so excited that he danced like a child.

"That's right, Old Li. I've confirmed it's poison gas bombs. Those green ones are tear gas. Tear gas is extremely irritating and can cause people to burst into tears, cough incessantly, and eventually have difficulty breathing, leading to death."

"Those red ones are sneezing gas bombs. They can paralyze the nerves and respiratory system, causing constant tears and sneezing. They can also kill people in a short period of time."

Zheng Kaixuan had a brief understanding of poison gas from some newspapers in his previous life.

"Third Battalion Commander, focus on attacking the enemy position in the southwest. The other three positions can be temporarily suspended."

Of the four ambush positions of the Japanese army, three are now filled with poisonous gas.

This poison gas is extremely powerful. The Japanese are also human beings and cannot resist it.

When thick smoke rose from several Japanese positions, Zheng Kaixuan knew that the Japanese in these positions were finished and there was no need to waste too many artillery shells on them.

However, there was no smoke in the Japanese position in the southwest direction, which showed that the Japanese in this position were using conventional artillery shells.

In fact, Zheng Kaixuan's judgment was not wrong at all.

The Japanese positions are now full of Japanese soldiers who are retching and wailing.

"Ah! I can't see."

Many Japanese soldiers' eyes were corroded by the poisonous gas and smoke, and they were in great pain and tears. They rubbed their eyes in agony and rolled on the ground.

"I can't breathe, cough cough cough..."

Many Japanese soldiers looked like they were being strangled by the neck, their faces turned the color of liver, their tongues stuck out, and they couldn't breathe normally.

"Cough cough cough cough cough..."

The sounds of coughing and vomiting continued to echo in the woods.

Some Japanese soldiers felt extreme itching on their heads, faces, and bodies after being contaminated by the poison gas. Unable to bear it any longer, they began to scratch themselves desperately. Many of them scratched their faces to pieces, looking bloody and miserable.

Of course, the Japanese soldiers with weaker resistance had no chance to scratch at all. Within two minutes of the poison gas spreading, these Japanese soldiers died of suffocation.

The Japanese soldiers with stronger physical resistance, who blocked their mouths and noses with towels and clothes, managed to hold on for a few more minutes.

But these few minutes gave them the feeling that life was worse than death!

"Bang! Bang! Bang! Bang..."

Many Japanese soldiers could not bear the extremely painful torture of being corroded by poison gas, and chose to shoot themselves and end their evil lives.

At the same time, Zheng Kaixuan led the air flight team and successfully arrived around the Japanese positions.

Some Japanese soldiers who were originally on the outskirts of the woods and escaped from the woods as soon as possible were hunted down.

The soldiers from the 1st and 9th Battalions also surrounded the enemy from all sides and built a huge encirclement outside several of the enemy's positions, trying not to let any of the enemy escape.

Inside the woods, Matsui Shunsho's face turned ashen.

Half of it was due to the poison gas, and the other half was due to anger.

"Bagayadee! Zheng Kaixuan! You're so cunning! You're making me so angry!"

The reason why Matsui was not killed by the poison gas was mainly because his protection was relatively comprehensive.

While the Japanese were developing poison gas bombs, they also developed a number of protective devices.

However, this protective device is relatively simple and not very effective. The quantity is also extremely limited.

Matsui only got about 50 sets of protective equipment.

These protective devices can isolate about 70% of the poisonous gas in a short period of time. However, if you stay in an area filled with poisonous gas for a long time, it will not work.

But there was no way. Zheng Kaixuan had already led his men to surround the outside of the woods, and Matsui didn't dare to go out at all.

However, the preparations Matsui made this time were indeed very sufficient, and he himself was also afraid of the poison gas leak.

Last night he ordered his devils to dig several large holes in the woods.

This forest is located on the top of a mountain. The soil is extremely hard. We dug down very deep before we found a lot of big rocks. It was very difficult to dig.

Hundreds of Japanese soldiers worked all night and only managed to dig out three holes in the ground, each of which could only accommodate a dozen or so Japanese soldiers.

Now Matsui is hiding in the cave, coughing and crying.

"Zheng Kaixuan, I admit that you are very powerful, but the one who will have the last laugh must be me, Matsui Shunsho!"

Inside the underground cave, there is not only water and food, but also a radio!

"Contact the 3rd Infantry Battalion immediately and order them to attack the Sharp Knife Regiment's rear!"

Matsui Shunsho, who had suffered a great loss at the hands of the Sharp Knife Regiment, understood that one should not put all his eggs in one basket. This time, he did not ambush all his troops near the prisoner-of-war camp.

The Matsui Regiment consisted of 3800 people, of whom were ambushed within four kilometers around the prisoner-of-war camp and divided into four positions.

As for the other 1800 people, they were divided into two groups and all ambushed seven or eight kilometers away.

In this way, in terms of tactics, it was still the Matsui Regiment that formed a siege on the spearhead regiment.

Even Zheng Kaixuan, Li Yunlong and Xing Zhiguo had not anticipated this.

The most important thing is that these outermost devils found several caves suitable for hiding and hid very tightly.

After receiving Matsui's order, nearly two thousand Japanese soldiers, under the cover of artillery fire, suddenly rushed towards the artillery and logistics troops at the rear of the spearhead regiment.

Matsui Shunsho's move really surprised Zheng Kaixuan a little.

After all, there are not many Japanese who can gain a slight tactical advantage over Zheng Kaixuan.

But he soon regained his composure.

If it were other troops, the logistics support department and artillery unit would probably be in a panic for a while if they were suddenly attacked, and the situation of the battle might even be reversed.

But the Spearhead Regiment is not an ordinary force, so this is not a big problem for them at all.

"Artillery Battalion! Take out the enemy reinforcements' artillery fire, and the drone team will assist."

"Guard Battalion, Logistics Weapons Support Team, Charge!"

In the spearhead regiment, whether it is the soldiers responsible for logistical weapons support or the soldiers responsible for guard work, they are not much worse than the first battalion responsible for charging into battle.

After all, this is a unit where even the regiment commander often leads the charge, and everyone in the regiment is an elite!

Niu Dashan led hundreds of soldiers and rushed towards the Japanese reinforcements like a crushing force.
