At the beginning, the Yan army arranged an army of 30,000 in Henan County, which was led by Murong Zhong, the general of Ningdong of the Yan State, and Murong Chen, the general of Zhennan. But later, Murong Chen led his army south, and took advantage of Xie Wan's defeat to capture Yingchuan and Xiangcheng counties, leaving Murong Zhong and a group of generals in Henan County to defend it. And Xuchang was defeated, Murong Chen died and never came back.

It was not until later that Huangfu Zhen took over the position of general of Zhennan and led an army of 50,000 to the south to arrive in Luoyang City. Therefore, Huangfu is really the highest general of the Yan Army in Henan County, but he is not there now.

In the entire Henan County, except for some of the soldiers and horses that Murong Chen took away, there were only 10,000 people left. Because Huangfu Zhendong went to cooperate with Murong Chui and took away 30,000 horses, there are actually 30,000 troops in Henan County today.

However, after these armies were dispersed to various counties and passes, they were actually not very many. And a considerable part of the troops were placed in Henan County, Yiyang and Luhun counties, which were guarding against the Tang army.

Among them, Henan County is to guard against Chen Kang's headquarters stationed in Xin'an County, while Yiyang and Luhun counties are to guard against Zhao Ji's headquarters stationed at Gaomen Pass in the southwest of Yiyang County.

Because these two directions were the main routes for the Tang army to attack Luoyang and other places from the west, the Yan army had to be cautious.

Chen Kang had already resumed his position as a general because of his previous efforts to capture Huangchi and Xin'an County.

In addition, Li Xin previously transferred the town army of Hongnong and Shangluo to a regular army on the spot, so the number of troops in the hands of these two people at this time also reached about 20,000.

As soon as they received Li Xin's order, they immediately went into action. Because they had to act together, Chen Kang quietly rushed to Gaomen Pass from Xin'an County in advance and met with Zhao Ji.

"Your Highness ordered us to send troops, and now we can finally move. Since the two of us were transferred here, I haven't moved my muscles for a long time, except for the battle a few years ago. Look at Shao Zisong, he and I were both young generals at the beginning, and now they are both Weiyuan generals with four products! After the two met, the first thing they said was not how to fight the war, but they both had a sense of excitement, and Chen Kang said bluntly.

"I'm pretty much the same! You've fought a battle anyway, and since I arrived in Shangluo, I've basically just been training to get by. Now it's finally our turn! This time we have to make a show! Otherwise, I don't know when such an opportunity will come again! We have to be careful~ things, especially not to make the same mistakes as you did before! Although Zhao Ji was also excited, he still kept his consciousness and hurriedly reminded.

"Look at what you said, how can I forget it? I finally got back to the position of general, and I don't want to lose it again! Let's discuss it and see how we should do it! Chen Kang said with a smile.

"Your Highness's meaning is to hope that we can get the two counties of Henan and Xingyang into our hands. In this way, not only will the national border be pushed eastward a lot, but the most important thing is that Hanoi County on the north bank of the river can be suppressed! This will be much easier for us to solve the affairs of Hanoi County in the future! ”

"Your Highness is thoughtful, we can't compare, this battle hasn't started yet, we have already begun to think of Hanoi County!" Hearing this, Chen Kang couldn't help but sigh.

"Therefore, we must not let His Highness's plan fail, and we must find a way to achieve this goal. Now Huangfu Zhen led the army in Xingyang County, preparing to wipe out the Huanwen army in one fell swoop, and only 30,000 troops were left in Henan County to scatter all over the place, and this is a good time for us to act. In my opinion, we must fight a quick battle, you and I will send troops separately, and my side will lead the army to the northeast and take Yiyang, Luhun and Xincheng counties as soon as possible! And you, lead the army to take Henan County and Yique Pass! How is it? Zhao Ji nodded, and then analyzed.

"Okay, let's do it! After the three cities are taken, you will lead your army south to take Luhun Pass and the counties to the east. If it comes to this point, the Emperor's army should return! ”

"The strength of Huangfu Zhen's army is still above us, and if it comes back, it will be unfavorable for us. Fortunately, if these goals are achieved, then our advantage will be greatly increased. The most important point of this is Chenggao County, especially the Tiger Prison Pass, if we take it first, even if the Huangfu Zhen army wants to return to the army to rescue, it has to take a detour from the foot of Songyue South Mountain! Zhao Ji thought for a moment and said in a deep voice.

"In that case, we might as well start the war first. After Henan County and Yique Pass were taken, I immediately sent 2,000 cavalry to the Tiger Prison Pass in the starry night to control the city first. Then, let's seize the time to take all the places. The best thing is that the enemy troops in Luoyang and other places heard the news that the Tiger Prison Pass was captured, and they went out of the city to rescue them, so we can take the opportunity to attack them! Chen Kang nodded, and then said.

"Okay, if this is really the case, Henan County is just around the corner, and Xingyang County is not far away! However, these two thousand knights guarding the Tiger Prison Pass will inevitably face the enemy's front and rear attacks, and they must be brave to the death, so you have to choose the elite and let them know the danger of this trip in advance! When Zhao Ji heard this, he couldn't help but pat the case.

"Don't worry! There are many warriors in my Tang Army, how can there be people who are greedy for life and afraid of death! Chen Kang said proudly.

"Okay, then we'll settle it. As soon as you get back, you'll get ready, well, we'll do it together in two days! If you take Luoyang and other counties, you will hold the south of the river and the north of Songyue, while I will immediately lead the army into Yangcheng County, where we will wait for the army of Huangfu Zhen! ”

"Yangcheng County? But isn't it in Huan Wen's hands now? If you go like this, I'm afraid it's not good! Hearing the last sentence, Chen Kang couldn't help but be stunned.

"Yangcheng County is in the hands of Huan Wen at the moment, but when Huangfu really wants to return to Henan County, but he can't pass the Tiger Prison Pass, do you think Yangcheng County will still be in the hands of Huan Wen?" Hearing this question, Zhao Ji couldn't help laughing.

Seeing him look like this, Chen Kang also understood at once. Indeed, for Huangfu Zhen, who has an army of 30,000, when he sees the loss of the Tiger Pass, in order to rush back to rescue Luoyang, he will inevitably attack Yangcheng County at any cost.

Originally, Yangcheng County was in the hands of Huan Wen, and as an ally, it would be difficult for the Tang Army to seize it. But if Yangcheng County is captured by the Yan army, and then recaptured from the Yan army, there will be no problem.

Now the morale of the Jin army is low, and there are not many defenders in Yangcheng County. In the face of the menacing 30,000 Yan army, it is strange that it can be stopped. Zhao Ji's approach really made Chen Kang shudder. After all, it seems a little too insidious.

"Don't look at me like this, don't forget, we're all for Datang!" Seeing Chen Kang's expression on his face, Zhao Ji couldn't help but feel a little embarrassed, and hurriedly said.

"Of course! As long as it can bring benefits to our Datang, it is a good thing! Chen Kang also hurriedly said.

The two tacitly did not tear the layer of window paper, and after discussing the details again, they prepared to go.

As agreed, on the third evening after the meeting, the two of them began to act at the same time.

Zhao Ji quietly led an army of 10,000 out of Gaomen Pass in the evening, and rushed all the way to the northeast, advancing along the east bank of Luoshui.

Yiyang County is located in a key place, since ancient times it has been a place of urgency, and during the Warring States period, this place belonged to South Korea. The Qin State and Korea fought many great battles in this place, and finally the Qin State got it, so Yiyang County was set up.

At this time, Yiyang County was located more than 40 miles away from the southwest of Yiyang County in the later generations, on the shore of Luoshui. In fact, this place is still in the remnants of the Qinling Mountains, but because of Luoshui, there is a long river valley in the middle.

Although the mountains on both sides are not as tall as the main body of the Qinling Mountains, they are not smooth roads. As a result, this has become one of the main roads in Luoyang to the south. And if you go all the way up Luoshui, you will finally reach the high gate.

It just so happened that Gaomen Pass was now in the hands of the Tang Army, less than two hundred miles away from Yiyang County. Therefore, if the army moves quickly, it can reach the city in one night.

It is precisely because of the importance of Yiyang County that the Yan army put 3,000 men and horses in the city to garrison.

With such a force, it is generally not too much of a problem to defend the city. Even against an enemy army ten times larger than you, you can defend it for a long time if you take the right measures.

However, since Zhao Ji had the idea of a quick victory, he naturally wouldn't come with them to that upright siege method.

After all, the walls of Yiyang City are not low, especially once the army attacks the city, it is easy to delay time, and it is easy for the Yan army in other places to know the news and disrupt their plans.

Therefore, when the army moved, Zhao Ji himself led 2,000 cavalry first. Yu Zishi rushed to Yiyang City before.,Then,Send a message to the inner part of the city.。。

For example, in these counties and counties bordering the Tang Army, basically there are people from the staff division lurking in them. Especially in places like Yiyang, which have changed hands several times throughout the year, the personnel situation inside is very complicated.

Therefore, if you want to lurk some people inside, it is not difficult at all. These people usually don't show up, at most they only provide some information, but when it comes to the real moment, they can come in handy.
