When Zhang Sixing left the national defense line, it was already August 13, 1937.

When he left, there were only about 3,000 people left in the team of more than 8,000 people.

Six armored vehicles, all motorcycles, as well as cars and carriages. With the exception of the Jing'an soldiers on bicycles, all vehicles were able to fit everyone, which further accelerated their movements.

The reason why the Jing'an Army was taken away was that the guys in the Northeast were generally tall and had quite good physical fitness. In addition, in the future, military training will be held, and a guard army that will be completely under his command will be necessary.

He didn't want his base to be a difficult base to control in the future.

Behind them were the officers of the 72nd Army, who were sending off, and of course they unfurled banners. The only thing that Zhang Sixing didn't expect was that the officers and soldiers who saw him off behind him sang "The Soul of the Chinese Army".

This song, which is full of patriotism and fighting feelings, has become the most popular song at this time.

Looking at the distant convoy, Sun Yuanliang also hummed this song softly from his nose.

To his surprise, he heard his chief of staff, Zhang Baiting, actually singing this song with other officers and soldiers.

"Chief of Staff Zhang, have you done what I ordered you yesterday?"

Zhang Baiting, who was singing to the end, didn't notice Sun Yuanliang's words at all, which couldn't help but make Sun Yuanliang frown, and patted him to wake him up from his eagerness to protect his family and defend the country.

"Uh, Throne."

"Chief of Staff Zhang, let me ask you how you did yesterday."

At this moment, it was getting dark, and in order to avoid being disturbed by enemy planes, Zhang Sixing and his party set off in the evening. Hearing him ask about the progress of the arrangement, Zhang Baiting remembered, calmed down a little and organized the language, before the weapon,

"Junzao, the counties behind me have told us about our arrangements, and several counties have said that it is a good thing to find something to do for the farmers who are idle in the farm. So there is no problem with the price, they publicized it in the countryside, and according to statistics, it will not take about ten days, and they can make 400,000 to 500,000 clay porcelain shells. ”

Hearing such a number, Sun Yuanliang was stunned,

"So much."

"Commander, listen to the owners of those cellars, they only give the price of one copper and ten shells. This job can be done by adults and children, and the requirements are not high, and I heard that families who are quick can earn a dollar a day. ”

This looks at the income of the peasants in the range of about fifty yuan, and one silver dollar is worth one hundred and twenty to one hundred and forty copper plates. 500,000 clay porcelain shells are worth about 7,000 silver dollars.

The rest is simpler, directly throw the dried mud tires into the cellar to burn, and the small things do not take up space, and a cellar has to burn tens of thousands.

Then it's even simpler, just put the finished wax-soaked explosive block and the fire hose into it.

Hearing this, he frowned and said,

"Clay porcelain, this thing ...... waterproof"

"Don't worry, Principal Zhang has already thought of this matter, I have asked the technician of our repair institute to understand, and said that it is a good way to seal, so that we can rest assured."

Now Sun Yuanliang put his mind at ease, as long as he couldn't think of ten days, he would have more than 500,000 grenades under his hands. What kind of concept is that, when you encounter a devil, just throw a grenade.

If one is not enough, ten will be thrown, especially if the gasoline barrel cannon is fired, I am afraid that the Japanese infantry will not be able to cross the mine pool within 300 meters.

Because that thing threw out dozens of grenades at once, covering a large area.

Nodding with satisfaction, he asked again,

"What's that......"

"Steel helmet mines, explosives, dung, and shrapnel are not difficult to handle, but we don't have such steel helmets. But the military seat, the steel helmet mine is a stinky spot, but it is really ruthless when it explodes. Wherever there was standing in front of the mines, there was not a single living thing within thirty meters. ”

Seeing that Zhang Baiting, who had always been cautious, said a dirty word excitedly, Sun Yuanliang paid more attention to this steel helmet thunder.

"Then you haven't asked the people in the repair shop about this, without our steel helmet, we can't fight the iron shell."

"Junzao, that Principal Zhang also left dozens of steel helmet mines, and there are a bunch of Japanese steel helmets that can do a lot of ......"

"Hey, I said Chief of Staff Zhang, have you thought about why you can't withstand the attacks of tens of thousands of devils in the Sixing Warehouse without that guy. I think it's mainly this steel helmet mine, think about what you just said......"

They have all seen Zhang Sixing's demonstration, the pull-out version of the steel helmet mine. The tragic situation of the straw man who had been the target before, they all remembered it vividly.

The reason is clear, the Chinese army at this moment is often unable to withstand the Japanese cluster charge because of insufficient firepower.

Like the gasoline barrels and cannons that did not allow the Japanese to gain a foothold within 300 meters, they were a sharp weapon to restrain the infantry.

"Yes, Commander, I'll go to the armory and see if there's anything I can do with those four eyes."

The chief of staff who had been sent away looked at the convoy farther and farther away, his eyes lit up. Taking advantage of the fact that no one was around, he simply sang the war song of "the soul of the Chinese army" with the officers and soldiers.

But with excitement in my heart, I thought:

Arrange layers of steel helmet mines in front of the position, and then find hundreds of gasoline barrels, anyway, Lao Tzu has a lot of grenades. That's 500,000 every 10 days......

Thinking about the piles of grenades falling on the attacking Japanese troops, he felt a heartfelt excitement in his heart.

However, Zhang Sixing was not excited, at the moment he was lying on the armored car smoking a cigarette, silently thinking about some important issues.

Now he was faced with the question of where to build the base in the future.

He didn't say anything about it, because he knew that in the future, China's air power would be in the hands of an American.

He was Chennault.

But the Flying Tigers were founded in August 1941, not days before the Pacific War in December. Therefore, the Flying Tigers were not of much help to the difficult moments in the early stage of the Anti-Japanese War, at least not earlier than the Mao Xiong Aid China Flying Team.

But this is an idea, maybe the aviation school that Chennault is about to start can be run together with the paratrooper school. For Zhang Sixing, it is very convenient.

At least now it is possible to build new airfields in some places, and there are no American pilots to consider German or other national pilots. Of course, it is not for them to fight, but for them to establish aviation schools.

Of course, the main thing that trains is transport pilots, after all, there are no transport planes to engage in any kind of bullshit paratroopers.

However, when it comes to engaging transport pilots, having a few fighter pilots shouldn't be a big problem.

Now Chennault is already an adviser to the Chinese Air Force, and strictly speaking, he belongs to the category of foreign adviser officers.

But the biggest problem is that now Europe, including Taka-chan, does not want to touch the Japanese, so that their eyes are turned from China to the Pacific, and thus prevent the supply of weapons and warplanes to China.

Then we have to think of a way to train those paratroopers in advance.

How can paratroopers and paratroopers train without parachuting.

Of course, this matter is not very urgent, at least not the urgent problem now, and the urgent problem now is that he wants to ask Mr. Chennault where the aviation school will be built next.
