Yuguan Guancheng, for Pan Xiong, the first task has been completed.

However, the strategic plan to be implemented next is more difficult to choose and more arduous.

Hebei is surrounded by mountains and seas, surrounded by mountains and seas on three sides, and the Central Plains in the south. Blocking the Yuguan Guancheng could not completely block the connection between the Linhuang Mansion in the five capitals of the Liao State, the Liaoyang Mansion in Tokyo, the Dading Mansion in Zhongjing and the Xijin Mansion in Nanjing, and the later Emperor Taiji led the Manchu and Han Eight Banners to bypass the Shanhaiguan Pass, break through the Yanshan Pass, and break into Hebei, and even Shandong and Shanxi and other places.

Now, Cai Dao doesn't need to worry about Hedong Road, that is, the west of the mountain for most of the later generations, because there is a Zhe family there to fight against the Liao army in Yunzhou Mansion.

So when Pan Xiong successfully took Yuguan, the next step was to first capture the four important military locations south of Yuguan - Lulong, Qian'an, Leting, Zunhua and other important towns, relying on the Luanhe River to resist the attack of the Liao army from the south.

At that time, Cai Dao will send a naval army to assist the forbidden army along the Luan River.

Cai Dao's sneak attack on Yuguan was very well prepared, and his 500,000 troops did mobilize the enemy's deployment, which also made Pan Xiong less pressure.

The third step, after those important places north of the Luan River, the next step is a multiple-choice question given by Cai Dao to Pan Xiong.

At Gubeikou, and even Juyong Pass further west, Cai Dao left Pan Xiong to choose whether or not to send troops to capture and reject these two very important passes.

Gubeikou, a Great Wall was built during the Northern Qi Dynasty.

Here, because it is the rear of the Xijin Mansion in Nanjing, the Liao State, the defense is not too tight, so it is easy for Pan Xiong to capture here, but it is difficult to say that he can hold this important pass of the Great Wall.

This also has to test the construction speed of the 200,000 construction workers brought by Cai Dao, as well as the transportation speed of the Cai family's fleet.

If the construction workers can complete the reinforcement of Yuguan Pass before the Liao army can react, and build the completed fortifications on the north bank of the Luan River, then Pan Xiong will be very confident in defending against attacks from both sides.

And the next speed of the Cai family's fleet will directly affect Pan Xiong's choice in the future.

Therefore, before Cai Sansi sailed away, Pan Xiong forced him, just to want an accurate word. When will the other 350,000 Tuntian soldiers on Tamna Island be transported over quickly?

In the north, 50,000 Tuntian soldiers can be placed in Yuguan Guancheng, and on the north bank of the Luan River in the south, 300,000 Tuntian soldiers should be placed. Then, the 100,000 standing forbidden troops he now controls in his hands have become the key to occupying Juyong Pass and Gubeikou.

The sea is turbulent, and even the oldest crew members sometimes misestimate the weather.

Therefore, Cai Sansi did not make any promises to Pan Xiong in the end.

However, Pan Xiong finally decided to take a gamble.

He himself left only 2,000 personal soldiers, together with 100,000 construction workers, to protect the Yuguan Pass, and sent another 8,000 soldiers and another 100,000 individual construction workers to the north bank of the Luan River to build fortifications with all their might.

The remaining 90,000 standing forbidden troops were also divided into two groups, Pan Xiong let his two lieutenants, one lead a 60,000-strong army all the way to attack Gubeikou, and the remaining 30,000 people went straight to Juyong Pass.

Juyong Pass was still too close to Yanjing, and once the traces of the Song army were discovered by the Liao army, the situation was not good.

Fortunately, I don't know if it's God blessing, or if the army of Liao is too slow to react. Whether it was the Song Dynasty army that attacked the four military strongholds north of the Luan River, or the troops who attacked Gubeikou and Juyongguan, they were never seen by anyone before the attack.

Later, Pan Xiong and the two adjutants of the forbidden army learned that the local poor people in Hebei were either captured and sent to death by the Liao army as strong men, or they all hid in the mountains of Yanshan or Taihang Mountain.

The sky is beautiful, Cai Sansi's fleet traveled all the way, and the wind encountered was not strong, but it did not encounter any storms. It only took ten days, and under his leadership, his fleet completed the transportation of the last batch of reinforcements - the 350,000 Tuntian Army in one go.

Yelu Yanxi in Yanjing City and the other Liao royal nobles in Sanjing City were shocked when they learned the bad news that the Song army suddenly attacked and occupied Yuguan.

At this time, it was very difficult for Yelu Yanxi to send that out to cut off the grain route of the Song army, and recruit back the 50,000 cavalry who fought in the grass valley by the way.

On the side of Nanjing Xijin Mansion, Yelu Yanxi immediately ordered Nanjing to stay behind and recall the general Han army, and he personally led the palace division army to set off with this part of the Han army that had returned from the emergency edict.

Even if Yelu Yanxi is mediocre, he also knows that Yuguan is related to the life and death of the fat meat of Nanjing Xijin Mansion in Liao.

Once Yuguan cannot be recaptured, the Sixteen Prefectures of Youyun will definitely not be protected.

But then, the successive bad news blinded Yelu Yanxi, Lulong, Qian'an, Leting, Zunhua lost one after another, Gubeikou was lost, and the most exaggerated thing is that Juyongguan, which was very close to Yanjing Mansion, was suddenly lost.

The most exaggerated thing is that someone actually reported to him that Wanyan Aguta, the patriarch of the Jurchen Wanyan tribe, was a Yelu Abaoji-like figure, and this time, he signed an alliance with Cai Dao, the Taishi of the Song Dynasty. As soon as the Song army captured Yuguan, he immediately responded with troops.

Because the main force of the Liao army was pinned down by Cai Dao's 500,000 troops in Nanjing's Xijin Mansion before, the combined forces of the Jurchen tribes of Wanyan Aguta attacked faster, and now they have stopped troops under the city of Huanglongfu.

At this time, even a fool knew that he had fallen for Cai Dao's plan to divert the tiger from the mountain.

The Song army on two sides and the coalition forces of various Jurchen tribes oppressed the Liao State from three directions, and he was frustrated everywhere by blindly mobilizing troops like this.

After Yelu Yanxi left, Cai Dao immediately asked the 500,000 forbidden army to immediately pull out the camp and march towards the capital city of Nanjing Xijin Prefecture.

As soon as the Liao State Forward Army of Nanjing was in contact with the Song Army, it was still a cavalry against cavalry, and it didn't take half a day to be defeated and returned.

In this battle, Cai Dao did not send the troops of the forward Zhang Jianbei to meet the battle, but the troops sent were the elite of Cao Hu Shuiling's guard horses, and at the same time, behind this temporary vanguard battalion, there were also a large number of crossbowmen.

There are two reasons why Zhang Jianbei was not sent to fight.

First, let Cao Hu vent.

Cai Dao expected that after Yelu Yanxi left, the Nanjing garrison of the Liao State would definitely send a vanguard to fight with the Song army to test it, and if the Song army was vulnerable, he would continue to send a large army to hold on to the Song army as before. If the forward sent out failed, he would withdraw the Han army to the city of Yanjing and use the city to resist the attack of the Song army.
