Because of the doubts about Li Yuntian's whereabouts, Wen Du did not blindly pursue in the direction of Jiayu Pass, although Li Yuntian had the possibility of fleeing back to Lanzhou City to join Zhang Hao and other Ming troops, but this was equivalent to giving up the war in Guanxi, which made Wen Du suspicious.

At the same time, the scouts sent by Wendu investigated around Guazhou City, and finally discovered the movement of the Ming army two days later.

After Wen Du received the scout's message, he immediately knelt down on the map to check, and two important cities in the northwest of Guazhou City immediately fell into his sight, one was Qinglong City, and the other was the ancient city of Dunhuang.

This made Wen Du's brows furrow tightly, and for a while it was impossible to tell whether Li Yuntian went to Qinglong City or Dunhuang Ancient City, because both cities could be Li Yuntian's targets.

In Wendu's opinion, Li Yuntian must have been physically and mentally exhausted after being chased by him in the Gobi and the mountains for nearly two months, and most importantly, Li Yuntian lacked supplies, and it was difficult to continue to play the game of cat and mouse with him.

In fact, not only Li Yuntian, but Wendu is now also facing a serious shortage of grain and grass, and has begun to kill military horses for this purpose, the purpose of which is to bite Li Yuntian to the death.

Qinglong City and the ancient city of Dunhuang have the possibility of becoming Li Yuntian's destination, there is plenty of grain and grass in Qinglong City, and the high walls of the city are thick and easy to defend and difficult to attack, so it is the best place to hide, but there are 100,000 Timurid Empire and Northern Yuan troops outside the city, and there is a risk if Li Yuntian wants to go there.

There was also some grain and grass in the ancient city of Dunhuang, and the Timurid Empire and the Northern Yuan army besieging Qinglong City put the grain and grass base in the ancient city of Dunhuang to avoid being raided by the Ming army in Qinglong City.

Therefore, Li Yuntian also has a high probability of attacking the ancient city of Dunhuang again, and now Wendu does not know how many troops are stationed in the ancient city of Dunhuang, but it is certain that the number of troops will definitely not be too much, because Tuhuan and Hordu Khan should have carried grain and grass to Jiuquan City at this time.

According to the order given by Khordu Khan to Wendu, if Wendu could not destroy Li Yuntian before mid-June, then lead the army eastward, join him in Jiuquan City, and then attack the Lanzhou defense line of the Ming Dynasty.

Therefore, if Li Yuntian attacked the ancient city of Dunhuang, it was very likely that he would capture this defenseless city again, and then obtain food and grass supplies.

Whether Li Yuntian went to Qinglong City or Dunhuang Ancient City, Wen Du didn't have a clue now, but the time was tight and he couldn't think about it, so after carefully weighing it, he finally chose to go to Dunhuang Ancient City.

The reason is very simple, he did not think that Li Yuntian would choose to besiege the Timurid Empire and the Northern Yuan army outside Qinglong City with the Ming army of Qinglong City, after experiencing Li Yuntian's sneak attack on the ancient city of Dunhuang and burning the grain and grass in the city, the Timurid Empire and the Northern Yuan army besieging the city suddenly became nervous, and was afraid of Li Yuntian's prestige and began to practice.

Moreover, Wen Du hoped that Li Yuntian would fight with the besieging Timurid Empire and the army of the Northern Yuan, since Li Yuntian attacked the ancient city of Dunhuang, the furious Tuhuan and Khordu Khan had already issued an order, if there were those who were afraid of war and avoided war in Guanxi, they would be killed!

Although there was a conflict of interest between the Northern Yuan and the Timurid Empire, they had completely the same goal in dealing with Li Yuntian.

Therefore, after Li Yuntian led the army to capture the ancient city of Dunhuang, Tuhuan and Khordu Khan decided to eliminate Li Yuntian at all costs first, clearing the last obstacle for them to seize the Ming Dynasty.

In the silent night, outside the south gate of the ancient city of Dunhuang.

Li Yuntian was surrounded by everyone and stood on the hill where he had stood during the last night attack on the ancient city of Dunhuang, looking at the ancient city of Dunhuang shrouded in night with a serious expression.

According to the information obtained by Li Yuntian, there were a total of 20,000 defenders in the ancient city of Dunhuang, of which 15,000 were servant troops from the Western Regions and the other 5,000 were troops from the Timurid Empire.

Not only that, Li Yuntian also received the latest information on the movements of the Timurid Empire and the Northern Yuan army, the most important of which was that the grain and grass transported from Hami City arrived in the ancient city of Dunhuang in early May, and the Timurid Empire and the Northern Yuan army stationed in the ancient city of Dunhuang immediately escorted the grain and grass to the north.

If Li Yuntian didn't guess wrong, Tuhuan and Hordu Khan had already escorted the grain and grass to Jiuquan City at this time, which doubled the pressure on Zhou Zheng in Lanzhou City.

The south gate of the ancient city of Dunhuang was destroyed by Li Yuntian with explosives last time, and now two brand new gates are installed, and in the darkness outside the city gate are quietly ambushed heavily armed Ming soldiers, holding their breath and waiting for the signal to attack.

Naturally, those servants in the Western Regions were responsible for guarding the city gates, and this kind of laborious physical work would definitely fall on them.

At this moment, the servants who were patrolling the walls of the southern city did not notice the impending danger in the slightest, and still sat lazily under the walls and took a nap.

What is especially infuriating is that the crying of the woman and the lewd laughter of the man on the tower of the city gate of the south city continued until late at night, and it was obvious that the woman on the tower of the city gate was forcibly taken by those servant soldiers and suffered the **** of those servant soldiers.

In the early hours of the morning, when the earth was quiet, the closed gate of the southern city suddenly creaked and slowly opened, and a group of soldiers wearing Northern Yuan costumes came out from inside, holding torches in their hands and waving in the direction of the Ming army's ambush.

Seeing this, the dark night became active in an instant, and the Ming soldiers in ambush rushed quickly to the city gate with their weapons, and then slaughtered the servant army and the Timurid Empire soldiers in the city under the guidance of those soldiers wearing Northern Yuan costumes.

Soon, the sound of swords and swords resounded in the ancient city of Dunhuang, and a melee slowly began.

Li Yuntian quietly stared at the ancient city of Dunhuang, where there was a shout of killing, fires appeared in the city one after another, and it seemed that buildings were set on fire one after another, and the battle situation quickly spread to the whole city.

The soldiers wearing Northern Yuan costumes who opened the city gate were naturally pretended by the Ming army, Li Yuntian had no explosives in his hands, and even if there were explosives, it was impossible for him to blow up the south gate of the ancient city of Dunhuang, after all, he still had to rely on the city defense of the ancient city of Dunhuang to resist the siege of the Wendu army.

Therefore, Li Yuntian asked Tianyi and other soldiers of the Guanxi Army to pretend to be Northern Yuan soldiers to enter the ancient city of Dunhuang at dusk, and then captured the south gate at dawn and put the Ming army outside the city into the city.

Compared with the last attack on the ancient city of Dunhuang, the battle of the ancient city of Dunhuang appeared to be a little uneventful, in addition to the fierce resistance of the soldiers of the Timurid Empire, the servant army in the city can be said to be a touch of a collapse, and the battle with the Ming army occurred not long after the rout, and then they threw down their weapons and surrendered with their hands raised.

Don't look at the servant army showing off its might in front of the people, but the will to fight and combat effectiveness dare not compliment, it is a typical wall grass, which side has the most power.

Therefore, the battle in the ancient city of Dunhuang ended the next morning, except for more than 100 Timurid soldiers who resisted stubbornly in a house, all the rest of the place was pacified by the Ming army, and the streets were full of prisoners of war with drooping heads.

"Lord, we can catch a big fish this time, according to the surrendered soldiers of the Timurid Empire, the person who was surrounded inside is King Amman, the brother of Khordu Khan." Li Yuntian came to the mansion surrounded by the Ming army surrounded by everyone, and Tianyi, who was discussing the attack method with several military attachés, hurriedly greeted him when he saw this, and said happily.

"Oh?" Li Yuntian couldn't help but be surprised when he heard this, he didn't expect to have such a big harvest in Dunhuang City, no wonder those soldiers of the Timurid Empire resisted so fiercely.

The King of Amman is the half-brother of Hordu Khan, and although he is not a sibling, the relationship between the two is very good, and he is the most trusted person of Hordu Khan.

Speaking of the King of Amman is really unlucky, he was originally in charge of logistics in Hami City, Khordu Khan led the army to cross the Jiayu Pass to the east after he transferred him from Hami City to Jiuquan City, yesterday afternoon to the ancient city of Dunhuang, originally left early the next morning, did not want to be unlucky to meet the Ming army to attack the ancient city of Dunhuang, and then was trapped in this house.

The soldiers of the Timurid Empire in the courtyard are not ordinary people, they are from the guards of Khordu Khan, composed of soldiers who have experienced a hundred battles, and have strong combat effectiveness, which makes Tianyi and others have to give up the strong attack in order to avoid unnecessary casualties, and discuss the way to attack safely, if the King of Amman can be captured alive, it is undoubtedly a great achievement, which greatly boosts the morale of the Ming army in Kansai.

"Tell them to go down, bring some firewood, and set fire to them if the people inside don't surrender." Li Yuntian knew the thoughts of Tianyi and the others, but this also made them restrained, otherwise they would have captured this small mansion a long time ago, so he said quietly after a deep groan.

Tianyi was taken aback when he heard this, you must know that the high-ranking officials and dignitaries of the Tianmu Empire were in the mansion, but the next moment he was relieved, in the eyes of these Ming military attachés, the King of Amman was a treasure, but in Li Yuntian's eyes, he was just a captive.

So, under the beckoning of Tianyi, the Ming soldiers collected a lot of firewood from the city and piled it up in the open space outside the house, making the Timurid soldiers in the courtyard look out nervously through the crack in the door.

In addition to firewood, the soldiers of the Ming army also collected some fire oil and poured it on the firewood, and the air was suddenly filled with a pungent smell of fire oil.

"Listen to the people inside, our prince will give you a stick of incense time to consider, and if you don't surrender, you will set fire to the house!" At Li Yuntian's signal, Tianyi shouted at the Timurid Imperial soldiers in the courtyard.

After hearing Tianyi's shout, the Timurid Imperial soldiers in the courtyard suddenly made a commotion, obviously they had smelled the smell of fire oil, and felt that the Ming army didn't seem to be joking this time.

Li Yuntian stood in front of the courtyard gate with his hands on his chest and waited quietly, at this time the king of Amman has become a turtle in the urn, there is no escape, if he does not surrender, he can only choose death, he does not think that the king of Amman has the idea of death, after all, now the Timurid Empire and the Northern Yuan have the upper hand in the battle with the Ming Dynasty, even if they are captured, there is a great possibility of being rescued.

Tianyi's words lagged behind, and there was no movement in the courtyard, which made the situation at the scene suddenly become silent, and the soldiers with torches in their hands were expressionless waiting for Li Yuntian to give the order to set fire.
