Huangjiagou is located between Tiemenguan and Xifengkou, although it is called a ditch, to be precise, it is a valley, and it is a valley with a large area. The valley is trumpet-shaped, with a width of just over 20 meters at the smallest point and nearly a thousand meters at the widest point. To the south of Huangjiagou is a mountain range with the Great Wall, and to the north is another mountain range, and the two mountains are gradually moving away from east to west, and Zhou Qinghai, who is better than a monkey, did not place the ambush site at the narrowest east, but in a place called "Jiangjunkan" by the local people.

"General Kan" is said to be the place where Guo Ziyi, a general of the Tang Dynasty, once defeated the Koreans, and the reason why it got its name is that it is about half a meter high and nearly 10 meters wide on the left side of the stone slope. This rocky slope is about 100 meters long, just in the middle of the valley, and the old grass and new grass on both sides are entangled, and the depth is about half a meter. Zhou Qinghai is lurking in these weeds at the moment.

According to the usual practice, in Zhou Qinghai's troops, the Cadet Army assigned an officer similar to an instructor in a regular army. This son's name is Fang Hongming, only 19 years old, a student at Tsinghua University, and later put pen to paper, after two and a half months of intensive training at the Military Academy, he was awarded the rank of lieutenant. And because he was a local, he was sent to be Zhou Qinghai's deputy.

At the beginning, because he was worried that this young junior was here to divide his own power, Zhou Qinghai fortified everywhere and adopted a strategy of holding it high, and did not let him participate in the daily management of the troops.

Fang Hongming only did not know and did not raise any objections. Under Zhou Qinghai's nose, he asked this soldier to talk about his family, listen to that soldier's story, and occasionally organize one or two book listening sessions to tell the glorious deeds of some great heroes in history. Later, at the request of several fighters, they began to organize character classes to tutor the fighters in culture. Since he never interfered in the construction and management of the army, although Zhou Qinghai knew that his move was to win people's hearts, because he was very respectful to himself, he could not have a seizure, so he gathered more and more soldiers around him under his nose and established the so-called reading club.

Later, as Zhou Qinghai became more and more identified with the Cadet Army, he became more and more ignorant of his measures that seemed to have nothing to do with army construction. Not only that, but there are also quite complaints in private, thinking that the political commissar assigned to him by the Cadet Army, although his culture is very high, is a bit too unprofessional. Of course, Zhou Qinghai's idea did not last long, because as he deliberately let Fang Hongming get in touch with army management, he was surprised to find that this young post-mortar had such a high prestige in his own army, whether it was some bandit-like old brothers in the past or a hairy young man who had recently been recruited, he was obedient and respectful to this political commissar. At this time, he suddenly understood that everything that the emotional family had done before had a purpose.

In war, Zhou Qinghai thinks he is an expert, but he is helpless in life and other things that have nothing to do with the war. In the past, he gave these to his brothers to play freely, although he didn't have any stubble, but the feelings were always too child's play. And since handing over these to Fang Hongming to take care of, he was pleasantly surprised to find that his grass feather army had the demeanor of the regular army of the Cadet Army.

At that time, he had to admit: "Damn, emotional reading is really good!" "For the first time in my life, I was in awe of reading and literacy. So, as the supreme commander of the self-defense brigade in Tiemenguan and the surrounding areas, he was the last to join the reading club and began to read and write with those soldiers.

Because he realized the benefits of reading and writing, and then there was a military operation, Zhou Qinghai refused to leave completely by feeling as before. Fang Hongming did not deliberately guide, but Zhou Qinghai knew how to treat the wisdom of the masses correctly - setting the ambush site at the "General Kan" was the result of convening the officers above the squad leader to discuss collectively.

Only half an hour after entering the ambush site, a "message tree" fell down on a small hillside 500 meters ahead. The "message tree" was naturally brought by Fang Hongming. And before this "news tree", every other mile, there were three "news trees", that is to say, when Hattori Yuanren's cavalry wing was still five miles away, Zhou Qinghai and they had already gotten the news.

Zhou Qinghai immediately picked up the binoculars, and in the distance, a cloud of dust rose up, and he whispered: "It's here!" All of a sudden, his spirits became excited. He said to Fang Hongming, who was lying beside him: "It's a big army." Fang Hongming nodded, and tightened the Wei Qing-style assault step in his hand.

Zhou Qinghai shouted to both sides: "Brothers! Get ready for battle, the devil is not far from here! ”

There was a sigh. Those who make a relatively small noise are some "old bandits", and those who make a louder noise are some new soldiers. If you look closely, you will find that the eyes of those old bandits are lit up as if they have lit torches, while those new recruits are a little nervous and nervous.

Zhou Qinghai looked at the Wei Qing-style assault step in Fang Hongming's hand, with undisguised envy in his eyes, and asked in a low voice: "Xiao Fang, if we win the battle this time?" Do you think the junior commander will make an exception to give us a regular army formation? ”

Fang Hongming turned his head, met his gaze, and then followed his gaze to the gun in his hand, he smiled and said, "I don't dare to say the establishment of the regular army, but a platoon of Wei Qing style should not be a problem." ”

"Okay!" Zhou Qinghai shouted, and then faced the somewhat surprised eyes of the brothers, he scratched his head and said, "Look at what I do, Lao Tzu is not a big girl." Keep an eye on the front and unscrew the lid of the grenade! The little devil arrived soon. ”

As soon as he finished speaking, he put his eyes closer to the telescope again, and exclaimed in a low voice: "Damn, it's a cavalry." ”

"Cavalry?" Fang Hongming was taken aback. Then he laughed and whispered: "Good cavalry! Now the chain of mines we laid can play a bigger role! ”

"Hey, hey! Lao Tzu personally went to pull a rope! As he spoke, Zhou Qinghai ran not far away, and snatched a rope from an old bandit to cause a mine.

The sound of horses' hooves reached everyone's ears, and a few minutes later, a pier appeared in everyone's sight. Zhou Qinghai made a gesture, and everyone clutched their weapons tightly, not daring to make a little sound. The noise all around them disappeared suddenly, except for the sound of horses' hooves, except for the heavy breathing of some recruits' eggs.

- A big war is on the verge of breaking out.
