This is a very difficult pass to overcome.

The difficulty is no less than that of Niangziguan.

At the beginning of the Battle of Xifengkou, General Zhao Dengyu led the officers and soldiers to fight with grenades and big knives, and the little devils continued to fight, and the big knife team organized used big blades to cut out the prestige of the army and cut out the backbone of the nation.

Now Zhang Dabiao is also hindered at Xifengkou.

Li Yunlong thought for a while and said: "Because of the terrain, Xifengkou is completely a one-man pass, and it is completely unfavorable to the development of the large army!" No matter how many troops there are, it's useless! ”

"In this way, let Yu Fei's air force aviation formation go to support the Northern Expeditionary troops, attack the little devils at Xifengkou, and then let Zhang Dabiao organize elite troops to attack the 11th battle!"

"I see!" Little Joe nodded.

Zhang Dabiao is the earliest veteran who followed Li Yunlong, and he is a brave and resourceful tiger general, but compared with Li Yunlong, he is not a level at all, which is also the reason why the Northern Expeditionary troops have been attacking slowly.

However, Zhang Dabiao, a veteran of the most iron-blooded brigade, did not gain nothing, and the Northern Expedition troops along the way have also grown from the initial 20,000 to nearly 40,000, and the combat effectiveness of personnel and equipment has been greatly improved.

Now Nanjing has been attacked, but Li Yunlong's ultimate goal is Shanghai, so Li Yunlong began to formulate Shanghai's combat strategy.

Shanghai is located on the west coast of the Pacific Ocean, the eastern edge of the Asian continent, the center of China's north and south coasts, and the confluence of the Yangtze River and the Huangpu River. It is bordered by the Yangtze River in the north, the East China Sea in the east, Hangzhou Bay in the south, and Jiangsu and Zhejiang provinces in the west.

Because Shanghai is an impact of the city, the average height is about 4 meters above sea level. In the west, there are remnant hills such as Tianma Mountain, Xue Mountain, Phoenix Mountain, etc., and there are rock islands such as Dajin Mountain, Xiaojin Mountain, Fushan, Sheshan Island, and Xiaoyangshan Island in the sea area.

If he wants to attack Shanghai, one of the problems that Li Yunlong still needs to consider is the problem of the sea, the Japanese army must have warships on the coastline, and now the naval strength of the Iron and Blood Brigade is almost zero.

It is undeniable that the strength of the Japanese Navy during World War II was very strong, the Japanese Navy basically became the third largest navy in the world in 1920, and the ten aircraft carriers under the Japanese Navy were one of the largest and even most advanced aircraft carrier fleets in the world at the beginning of the Pacific War.

Later, the United States and Japan went to war, and at the beginning of the war the US Navy had seven aircraft carriers, but only three in the Pacific. And only one of the eight aircraft carriers of the British Royal Navy is in service around the Indian Ocean. Until the advent of the "Essex class", the "Shozuru-class" aircraft carriers of the Japanese Navy basically had the most advanced equipment in many aspects.

Between about 1692 and World War II, the British Navy was the largest and most powerful navy in the world. However, Japan has come from behind, and its overall strength has become the second largest navy in the world after the United States.

According to Li Yunlong's conjecture, the Japanese naval fleet must have covered the whole of Shanghai, and then the entire iron-blooded brigade would be in a state of being bombed.

"This Japanese Navy is a headache!"

When Li Yunlong was thinking about how to deal with the Japanese Navy, Wei Dayong walked in and said, "Division commander, someone outside wants to see you!" ”

"Who?" Li Yunlong looked up at Wei Dayong and said, "I'm busy now!" ”

"He said he wanted to fight you."

"Beat me up for a devil? It seems that he is a hot-blooded man who wants to join the Iron Brigade! Li Yunlong didn't care too much and said: "You let him go to the quartermaster's office, if he meets the conditions, he can join the Iron Brigade!" ”

"But this kid is stubborn!" Wei Dayong said: "Listening to the report of the guards in the front yard, this kid has done several of our brothers with his bare hands, and it seems that he has a few brushes!" ”

"Oh?" Li Yunlong is interested now.

The soldiers of the Iron Blood Brigade are not vulgar people, they are all veterans of a hundred battles, especially the elite soldiers under the Duan Peng Guard Regiment, especially those who are in charge of the garrison headquarters.

But this person can overturn these warriors with his bare hands, either he is a veteran of a hundred battles, or he is a practitioner.

"I just want to see who dares to make a big fuss about my Iron Brigade."

Li Yunlong was very curious, and then walked quickly to the front yard with Wei Dayong.

In the front yard, a tall man dressed in a common person's costume with two box pistols pinned to his waist looked very powerful.

The man was in a fierce confrontation with the Predator at this time, surrounded by a circle of warriors, all of whom were pointing their guns at the man, very vigilant.

At this moment, the four Predators fought with the man with their bare hands, two of the fighters hugged the man, and the other two warriors quickly pounced.

"Drink ......"

I saw the man shouting, looking at the two fighters who rushed over, and directly and quickly blasted out his fists.

"Bump!"

Fists struck at the two Predators.

The two warriors flew out upside down and landed on the ground.

The next moment, the man grabbed the two warriors who were bending and hugging his waist with one hand with his left and right hands, and then threw it away with a forceful flick of the Predator who was holding his waist.

The power is huge!

"Bang Bang Bang ......"

At this moment, a burst of applause suddenly rang out.

Unusually loud.

Everyone followed the prestige, and suddenly saw Li Yunlong, Wei Dayong and others walking out, and they all saluted with solemn expressions.

"Brother is so skilled!" Li Yunlong looked at the man with a smile and said, "A few Predators can't get close to you, dare to ask your brother's surname?" ”

The man spoke loudly: "Wolf poison flower Xiao Yan! ”
