Miao Mu Linqing and some Japanese generals and officers in the Guannai all ran in the direction of Guannan, and at this time, it was too late to go to the warehouse to get gas masks.

Because there happened to be a weak south wind tonight, the poisonous gas spread quickly with the help of the wind, and if you run slowly, you may be enveloped by the poisonous gas.

Therefore, the only way to make plans is to retreat to the south gate, where the poison gas has not yet spread.

The devils and puppet soldiers in the pass retreated in the direction of the south gate in horror, but the more than 1,000 devils and more than 500 puppet soldiers who stuck to the castle at the east gate were not so lucky.

Unprepared, they were almost instantly enveloped by the raging poisonous gas, and they fell down weakly.

After the ten rounds of poison gas bombs were over, the Longya artillery outside the pass immediately switched to conventional shells, taking advantage of the chaos of the Japanese puppet army in the pass, to extend the shelling as much as possible towards the pass.

The fierce artillery fire roared, and in an instant, the gate was blown up in flames, and the dust and smoke were everywhere.

At the time of the fierce bombardment of conventional artillery shells in the pass, hundreds of Japanese puppet soldiers such as Miao Mu Linqing had already fled to the South Gate Castle.

Therefore, Miao Mu Lin Qing and other devils had a rare respite, and the old devil wolf bèi gasped unbearably, beckoned to a lieutenant and ordered: "Quick, order the soldiers, prepare wet towels to apply their faces, and then go down to the munitions warehouse in the customs to get gas masks." ”

"Hay!" The devil lieutenant immediately bowed his head and took the order to leave.

Another devil lieutenant stepped forward and said: "Your Excellency, the East Gate Castle is the first to bear the brunt, the defenders will definitely suffer heavy casualties, we must do our best to organize troops to go to the East Gate to reinforce, in case the people of China take the opportunity to attack!" ”

Miao Mu Linqing nodded and said: "It makes sense, order the troops, after getting the gas masks, immediately rush to the east gate to garrison, and must not let the Zhina army take the opportunity to attack in." ”

However, Miao Mu Linqing obviously underestimated the operational ability of his own troops and the attack speed of the Dragon's Tooth Column outside the city.

First of all, the devils and puppet soldiers who retreated to the south gate area were in extreme panic because of the suddenness of the incident, and at this moment, many of them were awakened from their sleep, and many of them didn't even have time to wear military jackets, so it would be good to be able to run out of the barracks in the customs with weapons.

In a hurry, where is there time to get towels and other items, and because it is summer, the weather is relatively hot, and a small number of Japanese puppet soldiers stationed at the south gate do not carry towels and other things.

Under such circumstances, Miao Mu Linqing's military order arrangement could hardly be carried out smoothly.

Therefore, when the second round of poison gas shelling of the Longya Column outside the pass began, until the end, none of the Japanese puppet troops at the south gate of Niangzi Pass could rush to the east gate for reinforcements because of the poisonous gas in the pass.

"Kill! Come on! With the end of the third shelling, the five hundred elite soldiers of the guard regiment, who had been waiting for a long time, under the personal leadership of Zheng Yunshan, brazenly launched a charge towards the defenders, who could be said to have been killed and wounded.

Miao Mu Linqing heard the faint shouting of killing outside the east gate, and couldn't help but be anxious, and said: "Bagaya Road, hurry, go and reinforce the east gate, you must not let the Zhina army attack in, hurry up, and do not hesitate to pay a price!! ”

Several devil lieutenants and a group of Japanese puppet soldiers rushed down the south gate regardless of a qi qi qi and ran in the direction of the east gate, but many people did not rush to the east gate because they broke into the poisonous gas area and inhaled too much poisonous gas, and they were poisoned and fell down.
