At midnight on February 29 (around 2 p.m.), 27,000 cavalry from the Beijing camp crossed the Yu River and arrived at Shunyi.

Since the Tuncheng was broken before February 23, tens of thousands of soldiers were captured to attack the Ming Dynasty in three ways.

The first route, under the command of Daishan and Abatai, arrived at Shanhaiguan on February 24, and has been storming for five days now, and Shanhaiguan is still moving.

The second route, led by Azig and Zilharang, approached Jizhou Town on February 26 and launched a fierce attack on Xifengkou, and the defender Li Jie was strictly defended.

The third route is led by Hauge and Mandahai, and is still heading west, and it is not known where the army will be marching.

Liu Hongjian ordered the Jinyi Weiti cavalry of this small banner to divide into three groups and continue to explore the latest movements of the Jianyu Third Route Army.

At midnight on 29 February (around 8 p.m.), the Jingying army arrived at Pinggu and stationed in Pinggu.

The sudden arrival of the 27,000-strong army frightened the only 100 sloppy guards who were waiting to die in Pinggu and fainted on the spot.

In the middle of the night, another group of small flag Ti rode into the camp of the Beijing army in Pingguzhong.

After investigation, the 40,000 Manchu and Mongolian troops led by Hao Ge followed the Longmen post of the Xuanfu defense line, passed through Kaipingwei, and were still marching westward, and many Han villages were slaughtered along the way;

After investigation, the battle at Xifengkou in Jizhou Town entered a stalemate, and Geng Zhongming's Han Eight Banner of Azig's department was the main force of the siege, with two newly made red-coated cannons of Jianyu, which were extremely powerful, and could bombard the city wall outside the attack range of the Jizhou defense line city.

The reason why Jinyiwei's intelligence is so timely and detailed is indispensable to the credit of Liang Yang, the commander of Jinyiwei.

As early as four days before Liu Hongji's army set out, Liu Hongjian issued the first military order to Jinyiwei, and Jinyiwei mobilized at least eighty percent of the cavalry to the north.

At least two of the cavalry of the Jinyi Guard were directly transferred to the outside of the pass, and the cavalry outside the pass were based on small flags, a small flag plus eleven flag officials, and a full two hundred small banners were scattered in the grassland and Liaodong territory of Nuoda on war horses.

Of course, Liu Hongjian will never treat his brothers badly, and all Tiqi who voluntarily goes on a 'business trip' outside the border will have his salary doubled, and there is a bonus (silver reward) when he finds out favorable news.

How important intelligence is, Liu Hong gradually knows better than anyone else that Jinyiwei, a specialized intelligence agency, takes the Jinyiwei Yamen in the capital as the core and the provinces in the northern border cities as the transit station.

For the purpose of Daishan, Azig, Haoge, and Jingying Army, they collected and probed information back and forth.

These Jinyi guards' cavalry roamed around to the east and north of Liaodong, and even the farthest had reached the periphery of Jianyu Shengjing.

There must be brave men under the heavy reward, and there is even a group of bold horsemen who took advantage of the darkness in the middle of the night to touch the camp of Azig and kill several Eight Banners soldiers who were responsible for the night.

When they came to deliver news to Liu Hongji, they even brought the head of the Tartar to receive the reward, and Liu Hongjian did not say a word, and distributed the reward on the spot according to the head of one hundred taels of silver.

This small flag officer even received a special commendation from Liu Hongji, and directly raised the general flag.

Another small flag is even more fierce, and the leader of the team is Liang Kewang, the nephew of Jinyi Wei and Liang Yang.

In the first battle of Qiantun, Liang Kewang, who had just turned 20, was shocked by the fighting spirit of Yan Yingyuan, the guard general of Qiantun, who regarded death as home, because he ignored his uncle's opposition and resolutely risked his life as an official of a hundred households.

This hundred-household official who can speak Tatar actually wore a Tatar military uniform and went deep into Dai Shan's Chinese army tent, if it weren't for the old Dai Shan's alertness, Liang Kewang even had the idea of assassination.

But Rao is like this, he still found out a news that shocked Liu Hong, the reason why Jian Yu was so familiar with the deployment of the nine sides of the Ming Dynasty was from a businessman surnamed Qi.

It's just that Jianyu seems to be very disdainful of this traitor, so much so that he doesn't call him by his first name because of the dog slave surnamed Qi, which causes Liu Hong to gradually make a guess.

Even if this surnamed Qi was a merchant from the Ming Dynasty, it was impossible for him to know about the deployment of the Nine Sides.

Unless the merchant has a doorway or a status!

There are too many nobles in the Ming Dynasty, and Liu Hong gradually didn't even know what the national lord called after a fight, and he didn't want to think about it for a long time.

In view of Liang Kewang's ability, courage, and excellent survey ability twice in a row, Liu Hongjian directly promoted him to the tenth thousand-household official who had been pending in Jinyiwei.

From the official of 100 households in the sixth grade, he directly crossed the deputy thousand households from the fifth grade and became the official of the 1,000 households in the fifth grade, and Liang Kewang deserved his name.

At noon on the first day of March, Liu Hong's troops gradually arrived at the right tunwei of Yingzhou, which was more desolate than the left tunwei of Pinggu, except for a dilapidated camp, there was not a single guard to be seen.

Liu Hongjian only had time to rest the war horses that had been attacking all morning for an hour, and then he had to march in a hurry.

Because the Jinyi Guard's cavalry brought them another shocking news.

Azig, who attacked Xifengkou, relied on the red-coated cannons with a longer range, and actually bombarded the Xifengkou city wall day and night, and the accuracy of the red-coated cannons could ensure that each cannon was fired at a distance of more than ten meters.

In order to find out the appearance of the red-coated cannon, the cavalry was even chased by a bunch of Tartar soldiers dozens of miles away, and several arrows were shot at the horse's butt before they could escape.

Of course, the Jinyi Weiti cavalry, who was chased by the Tartars, also gained something, and the people in charge of the two red-clothed cannons turned out to be a group of lustful people!

This group of people came from nowhere, and their operation of the red-coated cannon was so precise that a section of the city wall at Xifengkou collapsed under the constant bombardment around the clock.

Fortunately, Li Jie, the chief soldier of Jizhou, personally went into battle to plug the gap and repelled several strong attacks by Jianjiao.

What's even worse is that there are three such red-clothed cannons in Jianyu, all of which are in the hands of Dai Shan, and they are responsible for attacking Shanhaiguan, but fortunately, the cannons in Shanhaiguan are no less than the new cannons in Jianjiao.

But Rao is like this, and Liu Hongjian still feels a deep crisis.

The reason why the nine sides stand tall in the north and can keep the Tartars out of the city for hundreds of years is because of the strength of the city.

And now the Tartar soldiers have also learned to develop high-level artillery, as long as the nine sides still do not have the ability to fight in the field, then the border pass will be taken by Jianyu sooner or later.

After learning the urgent information of Xifengkou, Liu Hong gradually did not delay any longer.

The 27,000-strong army crossed Shimen Town to Zunhua, and after resting outside the small city of Zunhua for a night, Liu Hong gradually led the army out of Longjing Pass in the northwest of Zunhua.

On the second day of the first month of March, the 27,000-strong army finally circled around the periphery of Xifengkou.

At this time, many parts of the city wall of Xifengkou have been blasted open, and the battle for the defense of Xifengkou has been carried out to the point of fighting with swords......
