Xiao Ruxun strictly ordered before the war that he was only here to crusade against Yang Rebellious, not to burn and kill, and to plunder innocent civilians if there was a person who burned, killed and plundered innocent civilians, the military law severely punished.

This is not only to restrain the Qin army, he is still a little confident in the military discipline of the Qin army, the key is to restrain those southwest Yi soldiers who rely on the Qin army to march together.

Banzhou Yang's has the highest degree of sinicization in the southwest Yi Tusi, and the most developed political, economic and cultural development, which is very close to Bashu.

After coming to Banzhou, in the face of the crisis at the end of the Tang Dynasty, Yang Duan decided that the family would abandon Han customs and integrate with the local Yi people to survive the crisis and become a real Tusi, but since the two Song Dynasty, Han customs have gradually recovered.

Since the twelfth generation of Tusi Yang Zhen "Lebao North Twenty Miles Mujiachuan Landscape Beauty", "Tiger Car Ding Zunyi", more than 400 years, Banzhou advocating Confucianism, building a school and raising scholars, the customs have changed greatly, as if with the cultural relics of the Middle Earth, there are signs of atavism.

The rest of the families are very different from the Yang family in terms of cultural level, and the buildings that have been built in Banzhou, such as the city post station roads, etc., should not be destroyed in the war in Xiao Ruxun's view, and they can also save a lot of money after the war, and it will not cause turmoil in the territory.

Yang Yinglong is indeed arrogant and hateful, but the civilians in Banzhou are definitely not enemies, if they start killing, how can they be mobilized in the future?

Now it is necessary to accumulate trust, establish a sense of trust in their hearts for the officials and soldiers of the imperial court, and establish the image of the imperial court, which will be of great use in the future.

As for the An clan and the Song clan, they were also strictly restricted.

It is absolutely not allowed to burn and plunder the people of Banzhou, especially not to destroy the roads of the city, so when the army is approaching, Banzhou City has no defense, and the guards left by Yang Yinglong symbolically open the city gate directly to surrender.

Zheng Ying asked the army to be stationed outside the city to rest, and he led the army into Banzhou City to occupy it, and sent troops to garrison and protect the important government offices, and issued a proclamation of peace in the city, so that the people in the city who did not have time to escape could settle down.

An Jiangchen was frightened, but he was also a little dissatisfied, although he didn't dare to show it, but he didn't send troops to please Xiao Ruxun, he also wanted some benefits, the so-called emperor is not a hungry soldier, we will give you a war and show you the way, you should always let us get something, right?

What can we get out of the spoils afterwards? Don't you still have to rely on looting during war? In the past, when the Ming army and the Tusi army assisted in the battle, they all came like this.

But he himself said that he followed the pace of Qin Jun, how could he ask for special treatment now?

Zheng Ying clearly regarded this place as the land of Great Qin, and he didn't allow them to mess around at all.

Banzhou is rich, Yang Yinglong's property is something he misses, not to mention a good relationship and personal friendship, at this level, they are all superficial brothers, but the conflict of interest is not to the point where he has to tear his face.

Yang Yinglong is unlucky, how can he not get some benefits?

It's a pity that Zheng Ying didn't give him this opportunity, and didn't even let them in Banzhou City, and directly occupied it, hung up the national flag and military flag of Daqin, and announced that Banzhou City had changed hands.

The ancient city of hundreds of years has not been destroyed in the war, and it has not been razed to the ground.

On the afternoon of the eighth day of the first lunar month, under the guidance of An Jiangchen and Song Chengen, Zheng Ying and others cooperated with the sea dragon hoarding map detected by the secret agents, and had a full understanding of the sea dragon hoard.

How can a natural danger be had?

Hailong hoard is built on the independent Longyan Mountain of the east branch of the Da Lou Mountains, the lonely peak enters the clouds, the four sides are steep, the lower part of Longyan Mountain is a gentle slope with more soil, the upper part is a completely different cliff, the mountain is a slope with a radius of 5 kilometers, the new palace where Yang Yinglong lives is built, and the old palace of the Song Dynasty is different.

The new palace is a group of central treadways as the central axis, generally following the pattern of front and back sleep, with temples on both sides, as well as supporting facilities such as water prisons, vaults, silver warehouses, gunpowder pools, embroidery buildings, school dams and quarries.

It is completely the configuration of a small imperial court, which shows Yang Yinglong's ambition to fly freely, as well as the weakness of his control over local forces in the middle and late Ming Dynasty.

The surrounding mountain side, respectively in the east of Tun is equipped with copper pillar, iron pillar, flying tiger, flying dragon, Chaotian, flying phoenix six passes, in the west of Tun there are Wan'an, Xiguan and Houguan three passes, a total of nine passes; Under the mountain, there is Xiangshui, Baisha water circulation, the surrounding canyon is separated from the mountain, the canyon is deep, and the mountains are clustered.

Zheng Ying and the other generals boarded the Haiyuntun that had been breached, and watched the terrible fortress on the Hailong Hoard on the tun, their faces were solemn, and no one said the previous words again, even Zheng Ying himself felt a little tricky about the bold words he had said before.

Fifteen days to take here?

Fifteen days can be Tundong, Tunxi, that is, Tunqian and Tunhou, each conquering a level, which is considered good progress.

Although the scale of these levels is not as large as the rest of the levels, the key is that the roads are steep and narrow, and the Qin army needs to attack these levels from the back, which is equivalent to mountaineering, which means that the Qin army's siege weapon Hongyi cannon cannot be used.

Even if it can be used, it can only be carried with all the effort, and the efficiency is too low.

And if you transport a few more Hongyi cannons, it is estimated that the soldiers of the Qin army, cattle, sheep and horses will be exhausted to death, and if you go up, don't think about coming down, or it is more convenient to simply throw them down from the mountain.

"The first six passes and the three passes after the tun are all rebuilt by Yang Yinglong, not to mention the solid and thickened, there are watchtower fortresses everywhere, garrisons everywhere, firearms can be released, and the road is narrow, my army can't disperse, it is easy to become his live target."

Zheng Ying's chief of staff, Gu Tan, had a serious face, and said all the things he expected: "And the road on this mountain is not suitable for the Hongyi cannon to go up, the Hongyi cannon is too heavy to pull up at all, when attacking the Tongzhu Pass and the Tiezhu Pass and the back pass, it can still be used, if it breaks through the mountain, especially on the thirty-six heavenly ladders, it cannot be used at all, and the soldiers can only break through with flesh and blood, and the casualties will be very large." ”

Zheng Ying's face was not good, and the rest of the generals were not good, so he returned to the camp tent and looked up at the towering peaks, feeling a little helpless.

Although everyone successfully swept all the military strongholds around, the military fortresses such as the Chicken City and the Horse City were easily broken through by them, and the morale was high, and there was a great tendency to move forward, at this time, if the Hongyi cannon could not be used suddenly, the attack would be blocked, and the morale would inevitably be greatly hit.

It is easy to reduce morale and it is difficult to improve, not to mention the offensive deadline, Zheng Ying felt that Xiao Ruxun was here at this moment, and it was estimated that it would be difficult to break through the Sea Dragon Hoard's defense line within fifteen days.

However, there is a general way of attacking, that is, after dividing the troops to attack the front and rear of the tun, there are six passes in front of the tun and three passes after the tun, all of which are dangerous passes.

Of course, the difficulty of the attack behind the tun is slightly less than that in front of the tun, but there are more defenders, the defense is stronger, there are many checkpoints in front of the tun, and there are the most precipitous thirty-six steps of ladder, which can be called extremely dangerous.

If these levels are not broken, then attacking the Sea Dragon Hoard is just a joke.
