The French already knew that there was gold in this tunnel, and the Germans naturally knew that because of this, this position was attacked by the Germans for the past two days.

The Germans seemed to have a premonition that something bad was going to happen, and this time the attack was very intensive. The forward line had already rushed to position, and behind the breast wall in the rear, a steady stream of German troops was converging, ready to join the attack.

"Grenade preparation, grenade preparation." Just as the Germans rushed into a distance of 50 meters, Qin Zhiyuan issued an order in both Chinese and French.

The guns on the positions were quite sparse, only the machine guns were still roaring wildly, the riflemen stopped firing and were ready to throw grenades, and even the auxiliaries were preparing, which was one of their tasks.

Leaning slightly, countless smoke-emitting grenades smashed towards the Germans like hailstones, and the Germans were suddenly in chaos, some wanted to dodge, some wanted to pick up and throw back, and some of them showed madness, and rushed forward with a ridiculous howl.

As for the F-1 grenade, its killing range is very large, up to 35 meters, when thousands of grenades explode together, in front of the French position is a place of death intertwined with grenade fragments, whether it is dodging or charging, can not escape the grenade fragments cover.

The charging Germans were like waves crashing on a cliff, shattered into nothing and reduced to powder.

"Charles, Charles!" Qin Zhiyuan threw the grenade in his hand, and then turned back and called the engineer company commander.

"I'm here, sir, please." Charles, wearing a steel helmet, also carried a rifle in his hand, and it seemed that he had just been involved in the battle.

"Go call right away and call for artillery support." Qin Zhiyuan looked at the endless line of German skirmishers and called for artillery support to form a battlefield partition.

"Yes, sir, call for artillery support at once." Charles repeated the command, turning and burrowing into the tunnel.

At this time, Wan Wan did not dare to salute, which could only make Qin Zhiyuan the focus of the Germans' fire.

Two auxiliaries hurriedly ran behind Qin Zhiyuan with stretchers, and next to them, a French soldier with a shoulder injury was leading four or five people to stagger in the direction of the tunnel, these people were injured in the eyes, they couldn't see anything, they could only retreat to the tunnel one by one, now no one can take care of them, they need to save themselves.

Soon, the whistling of shells in the air, and then clouds of orange flames and clouds of smoke erupted in the German charging line. In the smoke, some Germans were blown to pieces by the violent explosion, some were thrown into the air by the impact, and then their limbs twisted and fell to the ground motionless, and many more were cried wolf by the bombing, rolling and crawling to find the crater cover, or silently speeding up the charge.

The momentum of the German charge was clearly contained, and although the Germans were still charging, their morale and intensity were no longer comparable to those just now.

"Master Qin, the lights in the tunnel are not on, we can't do that operation." Mao 18 came out of the tunnel wearing gloves and came to Qin Zhiyuan's side to ask for his life.

"Go to Charles and ask him to fix the lights." It is estimated that it is a matter of changing the light bulb, and this thing does not need Qin Zhiyuan to do it himself.

"I won't say it......" Mao Eighteen was so sad that he must pass the language barrier.

"Just point to the light, and he'll see what you mean." Qin Zhiyuan aimed at a German soldier and knocked him down with one shot.

"Qin Ye, this light is not on, the black light is blind, I just mean that he can't see the electric light." Mao 18 wanted to faint.

"Damn!" Qin Zhiyuan finally jumped out of the firing position, rolled into the trench, and then led Mao Shibai into the tunnel.

At this point, Qin Zhiyuan finally understood what the role of an officer was.

In the tunnel, Charles had repaired the light bulb, although the power supply was still unstable, and the light bulb was bright and dark like a ghost domain, and finally there was a light to reluctantly perform the operation.

Field surgery does not seek healing, but only seeks to control the injury, and then waits until it is sent to the rear. If the internal organs are really injured, and the injuries are too serious, then there is no need to save them, just wait for death. This is not ruthless, but determined by objective conditions, which is the current level of treatment, and France is seriously understaffed by the outbreak of war.

It is precisely because of this that those two knives in the Chinese workers are so valued. Chinese workers are good at treating bruises and gunshot wounds, that is, surgery, and surgeons are the doctors who are most needed in the war.

"Gas bombs, gas masks." Qin Zhiyuan heard someone shouting in French, ripped off the gas mask hanging on his chest and put it on his face, and then rushed out of the tunnel.

During World War I, poison gas was used on the battlefield, and in order to defend against gas damage, soldiers were issued with gas masks, and as long as they wore gas masks, poison gas would not cause significant harm to the human body. But if you are unfortunately poisoned, then you can only wait for death, or do a simple treatment to reduce the damage as much as possible, and there is no complete treatment.

Since April last year, the German army first used poison gas in the war, and then Britain and France were equipped with gas masks.

The French have been tortured by poison gas for more than a year, and they already know very well when to wear gas masks, but the Chinese do not know, and the language is not understood, Qin Zhiyuan is anxious, for fear that Qin Zhisheng, who is still fighting on the battlefield, will suffer heavy casualties because they did not put on the gas mask in time.

As soon as he got out of the tunnel, Qin Zhiyuan was relieved, he saw that the Chinese people had all put on gas masks, and it was Ian, the company commander of the infantry company, who reminded them one by one. Although the language is not comprehensible, Ian can use gestures to illustrate the meaning.

It seems that the Chinese regiment is not doing well, and the French have accepted them.

At the beginning of the battle, some Chinese soldiers were indeed in a hurry and panicked, and it was the first time that the Chinese went to the battlefield, and for the first time, they lined up to shoot "foreign adults" with real swords and guns, and it was normal for them to lose ground in advance and retreat.

As the battle progressed, the advantages of the Chinese soldiers began to be reflected, most of them because of their excellent body coordination, shooting accuracy is very good, comparable to the veterans in the French army, and many of them are even qualified for the task of "sniper". The Chinese soldiers are physically agile and can move from one firing position to another at the fastest speed, and can strike the enemy more flexibly. The French army usually throws grenades between 30 meters and 40 meters, and many Chinese soldiers are 50 meters away when they raise their hands, such as Zheng Dali's kind of livestock, which can throw 70 meters with a raised hand, which can be called a "humanoid mortar".

So, when the momentum of the German charge was stopped, many Chinese soldiers stopped shooting and threw grenades instead.

They withdrew from their firing positions, stood in the trenches, pulled out their positions, twisted their hips, and threw the grenades in the direction of the Germans in the most stretched posture, and the grenades were thrown high and far, the farthest could reach eighty or ninety meters, and this was the real "humanoid mortar".
