Shangjun City is Yulin City. It is located in the northernmost part of Shaanxi Province in modern times, adjacent to Gansu and Ningxia in the west, Inner Mongolia in the north, across the Yellow River in the east, and bordering to Shanxi in the south, and Yan'an City in Shaanxi Province in the south.

Thinking of Shangjun having to cross the Yellow River, someone may ask, how to cross the Yellow River?

Coincidentally, he went to war around February. At this time, the north was frozen, and the water of the Yellow River had already formed ice. The 200,000 troops crossed the Yellow River. He also sent a telegram to order Yang Zizong to bring concrete and steel bars to choose a site. They wanted to build a bridge on both sides of the Yellow River. Taking advantage of the ice now, otherwise, the difficulty would probably increase after the ice melts. Of course, how to build is the business of their engineering department, and he just gave an order.

During the Three Kingdoms period, Yulin City was called Shangjun, and this is the first purpose of Qingcang's trip.

He would use Yulin City as a springboard, then open up the entire Southern Xiongnu and let the Southern Xiongnu collapse. All its resources will belong to the Chinese army.

The area they visited was a windy and sandy Caotan area, which was green and had a lot of water. It was no wonder that the Southern Xiongnu occupied it, because the resources here were too rich, especially for the nomadic people on the horse's back, grassland resources were particularly important.

The Huns lived on the northern grasslands and lived a life of pursuing water and grass for their homes. They were ethnic groups that survived on the grasslands. Once they encountered a drought year, they had no food and invaded the famous agricultural ethnic groups in the Central Plains on a large scale.

This is only the resources on the surface, and the resources on the ground are not something that these people can foresee, but Qing Cang can do it. He learned from the geography book that this area is simply a treasure land.

Because the land is vast and sparsely populated, when they step into this land, they always feel that they have gone wrong. But when they see a large city on the grassland, they tell themselves that this is right.

Qing Cang, with his army of 200,000, stopped ten miles away from the city. At this time, the sky was getting darker. He was about to set up camp here, and he would just wait for tomorrow to dawn, and then drive the cannon into Shangjun City.

During this period, he had already sent spies to inquire about the enemy's situation.

When night fell, the camp was brightly lit, and the spies returned to the tent and reported: "Report to the commander, nearly 100,000 enemy troops were stationed in Shangjun city, and there were also a large number of catapults, crossbows, rushing cars, etc. in the city, and a large number of continuous crossbows were seen."

At this time, there were Zhao Zilong, Li Dian, Bai Yu, Liao Bao, Yun Zhongfeng, Le Jin and others in the tent. These people were all elites of the Feilong Army.

When the spy talked about the crossbows, Qing Cang already knew that all his technology had spread, which was one of the disadvantages of opening up. After he opened Huaxia City, the technology would most likely spread, so that everyone would develop on the same level. If he had not developed a cannon gun, he would be the same as them. In that case, he would have no advantage at all. If he wanted to capture such a city, there would be no need to think about not having 300,000 or 500,000 soldiers.

Zhao Zilong said: "Commander, if there are 100,000 people, we will use our cannons. It will take less than a long time for the city to be destroyed."

He had experience. At that time, the troops he brought were less than 200,000, and he only used musketeers to easily break a big city with 100,000 guards. That war was a success.

Bai Yu echoed: "Yes, Commander Zhao is very reasonable."

Not long after Li Dian joined the army, he did not make any comments, but was receiving new information.

"Tomorrow, I think it's up to me, Liao Bao, to take the lead and catch them all in one go!"

Le Jin said, "I don't think it's too hasty. It's ours, and they can't escape."

For a moment, the generals fell into discussion, with some propositions and some propositions waiting.

Qing Cang signaled them to be quiet, and he said, "I can't take this city in a short time, why? Because we know that the Huns are good at riding and shooting. If they give them a horse, they can gallop freely on the grassland. Because their speed is extremely fast, it has caused a lot of uncertainty in the use of muskets. At the same time, these people have a unyielding attitude in their bones. It may take some time to attack them this time."

Zhao Zilong hurriedly said, "The commander said it very reasonably, I underestimated the other party."

Qing Cang continued: "In the future, no matter who the enemy is, we cannot take it lightly to prevent the enemy from biting it back."

"yes!"

As for the others, they agreed and nodded to understand.

Qing Cang then asked the spy, "Can the Huns Khan be in the city?"

"Return to the commander, Yu Fuluo was not in the city. I found out a lot of information, but I couldn't find out where he was."

Shangjun can be said to be a relatively advanced and large city in the Southern Xiongnu. Yu Fuluo did not have this place, so he was puzzled where it would be.

Since he didn't know where he was, he gave up, and he asked again: "What other useful information do you get?"

The spy said: "This city has fewer moats than my Huaxia City. The city walls are stacked with blocks of soil, and it only has two doors in the east and west. According to my observation, there are a large number of traps outside the door, so we must deal with them carefully."

There are few stones there, so it is good to have earthen walls. Of course, earthen walls can save a lot of trouble from his attacks.

"Can you draw this trap?"

If the trap can be drawn and the entire army can be paid attention to, then their casualties will be controlled within a reasonable range.

"I have all remembered in my heart, commander."

"Come, bring paper and pen."

The spy quickly drew the traps, which were distributed on both sides of the two gates, mainly concentrated within a range of 100 meters. At that time, just avoid this place.

"Commander, I am just about these positions and not accurate."

Qing Cang picked up the drawings. Although the paintings were not very good, he also understood the paintings. He praised:

"It's very good. Commander Zhao, then you can notify our soldiers and be sure to avoid these places."

After saying that, he handed the paper to Zhao Zilong.

"Yes! I'll inform you now."

After Zhao Zilong went down, Qing Cang said straight: "You are doing well, and you will get 5,000 Huayuan, that is your reward!"

"Thank you, Commander!"

The spy was so happy that he deserved it. You should know that his duty was very dangerous. If you accidentally find it, you may be discovered by the enemy and you may be left there forever.

"Okay, let's come here today. You all go down and rest. As soon as tomorrow dawn, we will attack Shangjun! We will strive to capture Shangjun as soon as possible and return to victory."

"yes!"

The generals retreated, leaving Qingcang alone in the tent.
