After completing the task of guiding the city of Yizhou, the retired Portuguese officer Gao Kaus soon had a good reputation for being good at building cities in the Liaodong Left Route Army. Ｘ

Therefore, after the construction of the fortress of Yiju City was completed, Chen Renxi, the imperial historian of Liaodong Town, who attached great importance to the strategic position of Ulan Hada, recommended Gao Kaus-Teixeira to Ulan Hada.

But what did not make Gokaus Teixeira incomprehensible was that the Guiyi king Burhatu did not want him to build a fortress at all, but blindly asked him to build the mountain city of Ulan Hada as high as possible.

Although Gokaus Teixeira repeatedly explained to the Guiyi king Burhatu and his Han general Wang Zhenyuan that building a fortress was the most advanced way to build a city in this firearms age, and repeatedly explained to them that the higher the mountain city of Ulan Hada was built, the more dangerous it was, but in the end it could not convince Burhatu.

Although Wang Zhenyuan understood what it meant, he also knew that Yizhou City, Jinzhou City, and Ningyuan City were all building fortresses on a large scale, and he knew that what this Taixiyi officer said was probably right.

However, Wang Zhenyuan, who was the governor of the Guiyi Wangfu and the commander of the Ulan Hada Metropolitan Envoy Division, the more he understood it, the more he agreed with Burhatu's idea.

Although Gokaus couldn't figure out what was going on, he didn't care, as long as the Tatar client was satisfied with his work, and he was able to get paid a lot of money as expected, he didn't care what kind of castle you wanted.

And the kind of medieval castle-like architecture that towers high in the mountains is also the type of castle that he, a retired Portuguese officer, is familiar with.

Even more familiar with the architecture of a medieval castle than a bastion that has not been popular for a long time, the high Kaus Teixeira from Portugal is more familiar with the architecture of a medieval castle.

In this way, under the assignment of Chen Renxi, the imperial history of the Liaodong Town Supervision Army, the Ming Army on the left side of Liaozhen selected and eliminated the auxiliary soldiers of the baggage craftsman battalion and 3,000 craftsmen, and under the leadership of the guerrilla Jin Guoqi of the baggage craftsman battalion, followed Gao Kaus Teixeira, the red-haired devil, to Ulan Hada.

At Wang Zhenyuan's suggestion, Burhatu took out batches of cattle, sheep and horses in exchange for a large amount of locally produced cement from Rehe Town.

In less than a year, under the design supervision of Gao Kaus, a mountain castle was built in the style of European medieval style on the red cliff of Ulan Hada, which was already dozens of feet above the ground, with cement concrete and red striped stones mined on the spot.

Burhatu had never seen such a castle, but as soon as the blueprints of Gocaus came out, he immediately "fell in love with it".

As soon as the castle with its towering stone walls, towering towers, and spires everywhere was built, Burhatu moved in from his golden felt tent and never left.

And this unprecedented mountain city on the Mongolian steppe also made Burhatu, who had lived in danger of war since childhood, feel unprecedented safety and security.

Although the nobles of the Karaqin who moved with him to live in the mountain city still set up their more accustomed tents in the stone houses, these Karaqin lords unmistakably gave up the nomadic life of living in no fixed place day after day.

At noon on September 26, Huang Taiji led the main force of the Jianyu army to the north bank of the Yingjin River.

Then, under the escort of Yue Tuo and Zhai Sang and others, he took the ministers of Baylor who accompanied him in the army to the bank of the Yingjin River, and also built a pergola to look at the towering mountain city of Ulan Hada in the distance.

On the way to the horse, Yue Tuo had already explained to him the reason why he could not continue the attack to the south, but at this time, Huang Taiji was still taken aback when he saw the red mountain city standing on the red cliff in the distance.

As the Great Khan of the Later Jin State, he is also the lord of a country, how many times he has moved his mind to rebuild the Khan Palace in Shenyang, but he has not started construction because there is not enough gold and silver materials, and the poor Karaqin people in the impression have quietly built such a mountain city in Ulan Hada.

What kind of financial resources did the Southern Dynasty in the Great Wall have to build such a fortified city for the Karaqin people?!

Huang Taiji, who was full of confidence in leading the army, suddenly had a question in his heart, how likely is it to conquer the Southern Dynasty?

Looking at the wolf smoke rushing to the sky above the mountain city of Ulan Hada, Huang Taiji's heart was shaken for a while.

"Great Khan! I'm afraid it's not an overnight fortified city here! If our army stays here for a long time, the border army of the Southern Dynasties will definitely be prepared for it, and it will not be good for me for a long time! Think twice! ”

In the past two days, Yue Tuo has been thinking about this question, that is, whether to attack Ulan Hada Mountain City.

Moreover, Yue Tuo also tested Jaisang's attitude towards the attack on Ulan Hada.

Zhaisang, who was bent on revenge, hoped that the Jurchen army, which was extremely powerful in his impression, would attack Ulan Hada, but for Yue Tuo's hint that he wanted the Horqin people to attack first, he pushed left and right.

Yue Tuo also has his own opinion on whether to fight the mountain city of Ulan Hada.

For him, of course, it is better not to fight, although the army of the Houjin State is very strong, but the most suitable tactic is to fight face-to-face in the field, rather than one fortress at a time.

In his opinion, attacking such a fortified city in front of him is really abandoning the strengths and taking the weaknesses.

The reason why his own Great Khan Huang Taiji did not take the Liaoxi Corridor and did not fight the Ningjin defense line was not to avoid such a tough battle?

After Yue Tuo's words were finished, Huang Taiji quickly recognized it in his heart, but at this time, Mang Gurtai suddenly said: "Although the mountain city of Ulan Hada has gone south for a while, there is no need for the iron cavalry of my Dajin Kingdom to attack this fortified city!"

"In a certain opinion, my army can completely go around the city, and what is there to fear if he is left with a lonely city behind him?

"If he is willing to be a turtle with a shrunken head and can't hold out, then it is up to him, if he pursues from behind, I will ride 100,000 people from the Golden Kingdom, and no matter how many Karaqin people come, they will be sent to death!"

After Manggultai said this, Abatai immediately said: "What the three Belles said is right! If the Great Khan is at ease, please ride with a certain 10,000 iron, and a certain is willing to serve as a pioneer and take Ji Town directly! With the Great Khan personally leading a large army, the Karaqin people will definitely have no courage to leave the city! ”

After Abatai finished speaking, Huang Taiji's eldest son Belhaug, Oba Khan of Korqin, and Darhan, one of the eight ministers who had been accompanying him, successively expressed their attitude of detour.

After listening to these people's words, Huang Taiji was silent, and after a long time, he ordered the army to set up camp on the banks of the Yingjin River.

At the same time, Huang Taiji sent his henchman Tulai to lead the Zhenghuang Banner guard to swing a Niu Lu of 300 people, one man and two horses, and crossed the Yingjin River to the south of the outpost.

It was not until noon the next day that Turai led his army back and reported to Huang Taiji what he had seen along the way.

From the mountain city of Ulan Hada to the south to Daning and Balihan, there is a dungeon fort burning with wolf smoke every dozens of miles.

The forts in each place are not large, and it seems that there are as many as 1,000 troops and as few as 500 soldiers, but they are all built in dangerous places.

Moreover, within a radius of hundreds of miles from Ulan Hada to Balihan, there were no herds of cattle and sheep or Karaqin herdsmen grazing.

On the contrary, the further south I went, the more strange I felt, because on the often uninhabited grassland, I saw a series of low walls of earth and rock.

Obviously, the Karaqin people and the Ming army here have been fortified and cleared the wilderness, and they are fully prepared.

Turai was the son of Fei Yingdong, one of the five ministers of the Nurhachi era, and was one of the brave and resourceful talents among the Eight Banners of Jianyu, and he has always won the trust of Huang Taiji.

Therefore, for the news he brought back, Huang Taiji also attaches great importance to it.

After talking about what he saw along the way, Turai, who was about 30 years old, continued: "Great Khan, south of the mountain city of Ulan Hada to Balihan, there are dungeon forts on one side, and there are no traces of people on the other, and there are many horse retaining walls made of earth and stone!

"In the opinion of the slaves, I am afraid that it is a dangerous place there, and my army will attack all the way over, even if they are all captured, I am afraid that I will lose the opportunity for the soldiers to be taken by surprise! As for the edge of Jizhen Town, if the old teacher runs out of food, the consequences will be unimaginable! ”

After hearing Turai's words, Huang Taiji waved his hand to stop the other Baylor ministers who wanted to speak, and said categorically:

"I heard that Sun Chengzong, an important minister of the Southern Dynasty, has been reorganizing his armament outside the border of Jizhen for several months, and this place is definitely not sudden!

"Since there is preparation here, our army has lost the opportunity, so only by advancing westward and destroying Lin Dan Khan first can we regain the initiative!"

Speaking of this, Huang Taiji looked around at the Minister Baylor in the big tent on the banks of the Yingjin River, and then said: "I have made up my mind! The various ministries restrain the men and horses, and do not let the four go out to plunder!

"Before sunrise tomorrow, the army will be divided into two roads, the left and the right, with Yuetuo as the main on the left and Haoge and Zaisan as the second, and march west from the south of the Xilamulun River, bypassing the southern edge of Dashawo, and taking Dalainuoer east of Kuku and Tun!

"The rest of the men and horses are all on the right side, led by me personally, from the north bank of the Xilamulun River along the river to the west, detour north of Dashawo, to take Erenhot!

"The two armies on the left and right, one north and one east, must meet under Kuku and Tuncheng before the sun in October! Those who fail to arrive within the time limit will be killed! ”r
