At the same time that Qiao Youhua personally led the elite troops directly under the column to destroy the elite of the Japanese army that broke into the base area, after a few days of long travel, Jiang Haidong and the three finally crossed the Yellow River south and entered the Central Plains.

Today's Central Plains is still within the control of the National Revolutionary Army, so they traveled unimpeded and fast, and it took about a week to cross the Central Plains and reach the eastern foothills of Dabie Mountain and the north bank of the Yangtze River.

Compared with the Central Plains and North China, the situation in the two Huai and East China north of the Yangtze River is much more complicated. There is the New Fourth Army, the National Revolutionary Army, and even more devils, puppet armies, and traitors.

The situation is complicated, and the territory of the enemy is intertwined.

Fortunately, the comrades of the underground party had already received the news, and they joined Jiang Haidong and the three of them in a small town at the foot of Dabie Mountain, and then began to arrange for them to cross the Yangtze River south and rush to Nanjing.

With the joint escort and assistance of the New Fourth Army and the underground party comrades, three days later, Jiang Haidong and his men secretly crossed the Yangtze River from the Dangtu area and entered the Jiangnan area.

"Nanjing, after a three-year absence, Lao Tzu is back!" Looking at the direction of Nanjing City, Jiang Haidong said word by word from the bottom of his heart.

"It's a pity that this time Lao Tzu is here to hoe and rape, not to recover this thousand-year-old capital, but I believe that it won't be long before we can fight back, recover Nanjing, recover Shanghai, and recover the entire Jiangnan region!" Secretly made a wish, so he took two of his subordinates and rushed to Nanjing in disguise.

At this time, nearly half a month had passed since the end of the battle at Erlongshan, and in the past half a month, no enemy situation had been found along the Yellow River, and after discussing with Zuo Quan, Qiao Youhua decided to transfer the 4th Infantry Division back and continue to conduct regular military training in the hinterland of the base area, so as to improve the combat effectiveness of this division as much as possible.

The arsenal was still producing at full speed, the defense areas of the 1st and 2nd Divisions were all safe, and all regiments and battalions did not interrupt their training in order to maintain their combat strength except for normal defense.

The four roads in the base area have all been paved, and the repair of the Zhengtai Railway is about to be completed.

The entire base area can be said to be thriving at this time.

On the German side, Li Yansan and other more than 300 pilots who were sent out have also been properly arranged by the German government to enter several well-known military schools such as Berlin and Munich respectively to officially begin to learn flying skills and related knowledge.

The design drawings of the Leopard tank, Qiao Youhua also asked Long Yingwei to transfer them to the German consulate in Tianjin.

In addition, Qiao Youhua was not idle, he drew a number of simple design drawings of advanced rifles based on the information about semi-automatic rifles and assault rifles in his memory, and explained the methods and methods to the technicians of the arsenal.

Let them use the captured American Garand semi-automatic rifle as a sample to imitate or develop a more advanced rifle, and do not expect to develop a fully automatic assault rifle such as the AK47 at once, even if it is a successful imitation of the Garand.

Because, as long as this first step is successfully taken, and more advanced semi-automatic rifles are developed in the future, fully automatic rifles will never be a problem, it will only be a matter of time.

Sure enough, after another half a month, the Arsenal rifle engineers came with good news, saying that they could prevent the Garand semi-automatic rifle, and only needed to import some parts from the key production line from Germany and restructure it.

In fact, it is not surprising that with a lot of help from Qiao Youhua, a traveler who has been leading for decades and several generations of advanced rifle design concepts and materials, and there are Garand semi-automatic rifles that can be used as samples, if they can't be imitated, then it's really hell.

Qiao Youhua was overjoyed and immediately asked Long Yingwei to contact someone from the German consulate to provide the Germans with a list of required items to prepare for import.

As long as the Garand semi-automatic rifle can be successfully imitated, then the overall strength of the Dragon's Tooth Column will be on a higher level, just imagine, the German weapons are good enough in submachine guns and machine guns, artillery fire, tanks, armored vehicles, etc.

In addition, the semi-automatic rifle mounted unit, which has a greatly increased rate of fire, will be able to greatly compensate for the shortcomings of the infantry's insufficient firepower output, and together with all advanced German weapons, it will constitute an unprecedented firepower.

The overall firepower of the Dragon's Tooth Column has become more powerful than ever.

You know, the firepower of two Garand semi-automatic rifles can even suppress a dozen Japanese troops equipped with a crooked light machine gun.

The lowest firepower output of hundreds of thousands of troops has become a semi-automatic rifle that can shoot continuously, and when fighting, 10,000 guns can fire in a volley, and it can be fired in bursts, and then combined with a general-purpose machine gun, the firepower is dense, and the picture is too fierce to imagine.

Originally, the combat effectiveness of the dragon tooth column was stronger than that of the devil, and it would only be stronger at that time.

In the past half a month, Jiang Haidong and the three of them successfully infiltrated the heavily guarded city of Nanjing, where the Japanese puppet army was heavily guarded, and reconnoitred Wang Jingwei's puppet presidential palace and its surroundings three times.

I have a preliminary understanding of the garrison forces around Wang Jingwei and the rules of activity.

When the three of them returned to the small courtyard where they were temporarily staying, Jiang Haidong, who was walking in front, suddenly stopped, and raised his hand to stop the two subordinates, then raised his head and swept his eyes like a knife across the surrounding courtyard walls, and shouted in a deep voice: "Friend, since you are here, don't hide, come out and meet." ”

With a bang, about a dozen black figures suddenly jumped from outside the courtyard wall.

Everyone was holding a mirror box in their hands, and the muzzles of the black holes were aimed at Jiang Haidong and the others.

Jiang Haidong was indifferent, and the two subordinates behind him immediately pulled out their pistols, and a voice came from the hall of the small courtyard.

"I advise you to put your guns down, otherwise more than a dozen small charges will fire at the same time, and no matter how good your skills are, you won't be able to dodge, right? There is only one end, and that is to be beaten into a blood sieve! Then they were thrown into the Yangtze River to feed the fish! Before he finished speaking, a middle-aged man in a black suit and a black top hat walked out of the hall.

Jiang Haidong raised his left hand, signaled the two behind him not to act rashly, and asked the man in the black suit: "Are you a military commander or a central commander?" ”

"Hehe, how do you know we're not from No. 76?" The black-clothed leader smiled slightly.

"In that case, I think you already opened fire, but before that, you would have gone to see Hades a long time ago." Jiang Haidong's face sank like water, and he was very determined.

"What? What do you mean by that? The leader in black was taken aback by Jiang Haidong's words, and then looked at his determined expression, and the uneasiness in his heart rose rapidly, but he couldn't think of any link that he had missed.

"You don't think you're sure you've won, do you?" Jiang Haidong said with a mysterious smile.
