The death of the old man who poured the night incense was beyond Li Yuntian's expectations, he didn't expect that Beiyuan's intelligence network in Qinglong City was so developed, and he actually cut off the clues of the investigation in a short period of time.

Although this made Li Yuntian feel a little disappointed, but at the same time, it also made him feel a little inexplicably excited, if he easily removed Beiyuan's intelligence network, then he would definitely feel lonely during this time in Qinglong City.

Lu Minen was greatly annoyed by this matter, and ordered the people of the Supervision Department of the Guanxi Qinglong Battalion of the Xiaowu Army to make every effort to thoroughly investigate the Northern Yuan spies in the city, and the Northern Yuan actually built such a tight and perfect intelligence network under his nose, which made him lose face in front of Li Yuntian and Bai An.

The people of the Xiaowu Army's Guanxi Qinglong Battalion Supervision Department also realized the seriousness of the situation, in order to avoid disturbing the people of Qinglong City, they were loose on the outside and tight on the inside, and secretly strengthened the investigation of the residents of the city, if they did not crack the intelligence network of the Northern Yuan in the city, it would be a huge shame for them.

In fact, for Li Yuntian, being able to uproot the three contact points of the Northern Yuan in Qinglong City in one fell swoop has achieved his goal, not only giving the Northern Yuan a powerful counterattack to set fire to the rice shop, but more importantly, he can understand the operation of the Northern Yuan's intelligence network in Qinglong City from the three contact points that have been cracked, and then find out other contact points.

At the same time, the ancient city of Dunhuang.

The ancient city of Dunhuang has become a huge barracks, and the city is full of soldiers carrying weapons as far as the eye can see, and both the Timurid Empire and the Northern Yuan Dynasty regarded this fortified city as their base camp in the western part of the country.

In order to avoid unnecessary friction and conflict, the troops of the Timurid Empire were stationed in the east of the city, and the troops of the Northern Yuan were stationed in the west of the city.

The supreme commander of the Northern Yuan Dynasty is the Adai Great Khan, and the supreme commander of the Timurid Empire's army is the fifth Great Khan Khordu, who is the great-grandson of Timur, the founding Khan of the Timurid Empire, who is only in his thirties, and is known as the most Timurid Khan since the founding of the Timurid Empire.

Since Khordu took over the throne of the Great Khan of the Timurid Empire ten years ago, the Timurid Empire has launched a new round of expansion, conquering a territory that is even wider than that of the founding Great Khan of Timur.

For Khordu, he had already established a feat comparable to that of his great-grandfather Timur, and had laid down a large territory for the Timurid Empire.

However, in order to surpass the great-ancestor who was admired by the people, Khordu had to complete the cause that Timur could not complete, that is, to conquer the Ming Dynasty in the east and take the prosperous and rich Ming as his own.

With the experience of Timur's Eastern Expedition to the Ming Dynasty, Khordu spent more time preparing for the Eastern Expedition, and he wanted to fulfill Timur's last wish to restore the glory of the Mongol Empire to the time.

At this moment, the ancient city of Dunhuang, the palace of the king of Dunhuang.

The king of Dunhuang is the commander of the Shazhou guard, Tahar, who led his family into Qinglong City for refuge, and the palace where he lived became an empty village.

As the best residence in the Dunhuang Palace, of course, it must become the residence of the Great Khan of Khordu, and Adai Khan can only retreat to another residence.

In the reception hall of the Dunhuang Palace, a high-level meeting between the Timurid Empire and the Northern Yuan Dynasty was being held, and the Great Khan of Hordu and Adai Khan sat side by side at the top of the hall, and the chairs on either side of the lower head were sitting on the high-ranking generals of the Timurid Empire and the Northern Yuan.

The main content of the meeting was to raid the Daming Hetao area, and then cross the outer Great Wall to capture Datong City, and then take advantage of the situation to go south to take the Juyong Pass on the Inner Great Wall.

"Adai Great Khan, Ben Khan heard that the Juyong Pass of the Ming Dynasty has thick walls and many garrisons, if we can't capture the Juyong Pass as soon as possible, we will fall into passivity." After a general of the Timurid Empire finished introducing the battle plan, Khordu put down the teacup in his hand and said quietly to Adai on the side.

"Hordu Khan rest assured, the explosives in Ben Khan's hand are enough to open a hole in the wall of Juyong Pass, as long as there is no protection of the city wall, the defenders of Juyong Pass will be vulnerable." Ah Dai smiled slightly, looking confident.

This is not that he deliberately despised the Ming army in Juyongguan, but that the performance of the Ming army was too bad back then, if it wasn't for Li Yuntian's magical defeat of the Northern Yuan army in Liaodong, the Ming Dynasty would have changed the dynasty long ago.

The Timurid Empire and the Northern Yuan should now be thankful for the explosives left by Yang Sanyu, the Marquis of Chengning, in Heishui City, so that the amount of explosives in the hands of the Northern Yuan is enough to open a gap in the wall of Juyong Pass, which is also an important reason why the Timurid Empire and the Northern Yuan chose to raid the Hetao.

Although Juyong Pass is located between steep canyons, its walls are mainly made of bricks, which was enough to withstand any enemy attack before the explosives appeared, but with the appearance of explosives, the walls of Juyong Pass became its weak point.

Jiayuguan is different, Jiayuguan is mainly made of rocks, although its terrain is not as dangerous as Juyongguan, but the explosives in the hands of the Northern Yuan can not blow up a gap in the city wall, which is very important for the Timurid Empire and the Northern Yuan, once the explosives are wasted, they will fall into a bloody battle in Jiayuguan, which is a scene that Adai Khan and Khordu Khan and others are unwilling to face.

"Adai Great Khan, who are you going to send to command the army?" Hordu secretly breathed a sigh of relief when he heard this, and then asked, what he was most worried about was that the Timurid Empire and the army of the Northern Yuan were blocked out of Juyong Pass, and now that the Northern Yuan had enough explosives, the walls of Juyong Pass were not to be feared.

Because the sneak attack on the Daming Hetao area is very important, so although the Timurid Empire and the Northern Yuan Dynasty have negotiated the number of troops to be sent, the generals who lead the army have been undecided, and everyone knows that once the trip to the Hetao is successful, it will make a great achievement, so the generals are fiercely competitive.

"The first general is the main marshal, and the general Fenglei is the deputy marshal!" Hearing this, Ah Dai stretched out his hand and pointed to the two generals sitting on the left side of the hall and said loudly.

"See Hordu Khan!" The first and Fenglei who were sitting on the chair immediately stood up and saluted Hall in unison.

The reason why Yexian was able to stand out from the generals of the Northern Yuan Dynasty naturally relied on his father Tuhuan Taishi, who hoped that this battle could establish Yexian's position in the Northern Yuan army.

In the opinion of Tuo Huan, General Fenglei's military attainments and resourcefulness are second to none in the Northern Yuan, and he is enough to deal with the dangers from the Ming and Timurid empires by his side.

General Fenglei is naturally the former Wen Yongbo Gu Chen of the Ming Dynasty, the privy deputy envoy of the Privy Council of the Northern Yuan Dynasty, and the most trusted and relied on person of Tuhuan, the plan to defeat the Northern Expedition of Emperor Xuande came from Gu Chen and Lu Tianxing, who was alias A Qiu, and it was because the two of them knew the situation of the Ming Dynasty very well, so they could design such a perfect plan.

It's a pity that Gu Chen and Lu Tianxing's plan was ruined by Li Yuntian, and in the end, the bamboo basket was empty.

Although the Northern Yuan Dynasty suffered a lot of blows in the war a few years ago, Lu Tianxing did not give up revenge, so he launched another round of plans against Li Yuntian in the capital, but it was a pity that it ended in failure, if it wasn't for Gu Chen's arrangement, Lu Tianxing would have lost his life.

"He's Han?" When he dominated the appearance of General Feng Lei, Hall couldn't help frowning slightly, and looked at Ah Dai with some vigilance, he was very wary of Gu Chen.

"Holdu Khan, General Fenglei used to be the general of the Ming Dynasty, he was attached to my Dayuan more than ten years ago, and now he is the privy deputy of my Dayuan Privy Council, and he is loyal to my Dayuan." Ah Dai couldn't help but smile slightly when he heard this, pointed at Gu Chen and said, "A few years ago, my Dayuan's plan to attack Daming was written by General Fenglei, if it weren't for the insidious and cunning of Daming Zhongwu King, Daming would have ceased to exist a long time ago." ”

"Don't worry, the wind and thunder and the Ming are incompatible." Gu Chen knew that not only Khordu, but also the generals of the Timurid Empire at the scene would be wary of him, so he bowed to Khordu and said in a deep voice.

Gu Chen now has a big beard, if anyone has ever seen him in Qinglong City, they will find that he is the bearded man who left before the city gate closed in Qinglong City, and the middle-aged Hu man set fire to the rice shop to see him off.

As Li Yuntian had predicted before, since the day the Qinglong City was established in Dunhuang, the Northern Yuan Dynasty had noticed this city built by the Xiaowu Army and began to build an intelligence network in the Qinglong City, and the person in charge of this was Gu Chen.

Among those officials of the Northern Yuan Dynasty, when it came to scheming and strategy, Gu Chen and Lu Tianxing threw off those officials of the Northern Yuan Dynasty several streets, which was also the reason why the two of them were deeply reused.

"Hordu Khan, has your commander been decided?" Ah Dai saw that the generals of the Timurid Empire in the room looked at Gu Chen vigilantly, knowing that it was not easy for them to accept Gu Chen for a while, so he changed the topic and asked Hordu.

"General Lou Luo is the commander-in-chief, and General Burzi is the deputy commander." Hearing this, Khordu looked at the general of the Timurid Empire sitting on his right and said in a loud voice.

Ah Dai was taken aback when he heard this, and couldn't help but look at Wen Du, who was sitting in the first seat on the right side of the hall with an expressionless face, he knew that Wen Du was the first general of the Timurid Empire, and he never expected that Hordu did not choose him to lead the army to raid the Hetao.

However, Tuhuan, who was sitting opposite Wendu, looked as usual, and had already guessed this result, Wendu's defeat in Sunset Valley had damaged his reputation, and Timur's empire was not monolithic, which gave Wendu's hostile forces a reason to attack him, making him lose his position as commander of the raid on the Hetao region.

"Don't worry, Da Khan, we will definitely live up to our mission and will definitely take down the capital of the Ming Dynasty." Lou Luo and Bulqi stood up and said to Holdu in high spirits that they already knew that the main forces of the Ming Dynasty were in the northwest, so this raid would not encounter much resistance, and the wealth of the Ming Dynasty had long been coveted by them.

"Great Khan, the Hetao region has been run by the Ming Dynasty for many years, and the Mongols there may cause a lot of trouble for our raids." Wen Du saw the smugness on Lou Luo and Bulqi's faces, frowned slightly, and then solemnly opened his mouth to say to Holdu.

Li Yuntian has been operating in the Mongolian political envoy for many years, not only to win people's hearts, but more importantly, to make the Mongolian political envoy a solid defense line in the north of the Ming Dynasty, you must know that the Mongols are natural warriors.
