From yesterday to now, after 12 hours of bloody fighting by the Song army, a military town that runs through the north of the Saibei finally fell into the hands of the Song army.

At this moment, all the soldiers were celebrating, and the ships from Kaifeng had given the follow-up troops of the Song army excellent armor, well-forged weapons, and even meticulously crafted artillery and firearms, and this time they were full of confidence.

By this time, it was already dark, and a lonely moon hung in the sky, and all the stars around it were dim.

The whole city was caressed by the soft moonlight, and the breath of spring was already quietly staged.

In the Western Route Army of the Great Song Dynasty, Li Chuyun was the mainstay.

The previous group of soldiers were dressed differently from when they were in Tokyo, mainly because they had a lot of burlap bags and miscellaneous items hanging on their bodies.

Ordinary soldiers will have flints, knives, food bags and other things on their bodies, and soldiers also have a lot of weapon-related things, such as small bamboo tubes hanging on belts to order gunpowder and iron molds for clamping lead pellets. Each team also carried various tools such as knives and hammers on donkey carts and mules...... On the march and in battle, there is very little time on the battlefield, and most of the time it is a journey life of eating and sleeping in the open air.

However, now after the military rations are delivered to the camp of the Western Route Army in large quantities, the quality of their military career has improved.

At this moment, plus the capture of a Liao military town, the army is beginning to camp outside the city.

The big tent of the Chinese army has not yet been packed, and Zhu Wenwu has not come, and they are deploying and inspecting the affairs of the various battalions stationed.

At this time, in the barracks, there was a Song army general who was holding a map in his hand, and the whole person ran towards Li Chuyun's military tent.

After Li Chuyun received the drawing, he looked at it, and there were many martial arts students who had learned from the Great Song Dynasty martial arts beside him, including his son Li Jilong.

Li Jilong has spent time in military life in recent years, and the information is old enough, and he has been crawling and rolling in the First Battle of Bashu and the Battle of Northwest China for many years.

He saw a Chinese soldier coming over with a drawing, and when he saw the lacquer seal on the drawing, he knew that it was the handwriting of the general, so he immediately asked the soldier to show it to Li Chuyun.

The drawing has been expanded, and there are a lot of additions to the drawing.

The drawings were added to the scale by Zhao Dezhao, the king of Wei, but they are still very rudimentary.

In addition to a drawing, there is also a design drawing.

After Li Jilong unfolded, it was the design of a military town.

He looked at the artwork of the design and found a lot of good things.

The first place is the improvement of the design of defensive thermal weapons, he knew that the Song army now has firepower, so the design artwork added the function of defending against the external force of gunpowder.

Within the effective range, the one-mile range of the field bronze cannon also increased the perimeter of the siege of the ancient army in disguise. Therefore, when designing, try to make the volume can be greatly reduced, greatly reduce the construction cost, and only need to meet the garrison barracks, warehouses and other sites.

Judging from the whole drawing, it is a military fortress with a complete system.

In addition to the design, there is also a point that it is much shorter than the height of the original castle.

Because the defenders armed with firearms defended the city by firepower, not by the height of the walls. The height of the wall will also cause a blind spot in firepower, so the construction of fortresses and fortresses does not need such a high wall, and from the overall construction point of view, it can reduce the cost of building the city.

Unlike ordinary cities and fortresses, which are basically square, but in the end they understand that square cities are not conducive to crossfire and artillery have a large number of blind spots.

The urn city of the ancients is also called "Moon City", which is like an arc protruding, slightly increasing the firepower point.

Therefore, after summarizing most of them, the general supervisor designed the construction drawings of such a military town according to the actual situation.

Liuhua Castle!

The building on this picture resembles the flower of a fortress with six petals. Each "petal" is a two-sided horn that grows around the fortress; With the addition of the arc-shaped connecting edge between the two lobes, the figure actually has six corners and eighteen edges.

Wherever the enemy attacks from, they will suffer cross-fire from direct fire from about three directions.

Of course, this fortress is more vulnerable than ordinary castles when it is not supported by firearms, because it is shorter and smaller. Therefore, when designing, it is necessary to consider the weather in which rain affects the use of firearms......

…… The imperial court considered the firing points of artillery and arquebuses on this drawing.

The six-petal protrusion is a solid earth rammer, and a hole is dug in the outer wall to provide a beam as a cover, one can prevent the attack of catapults, and the other can shelter from the rain.

Outside the physical fort, the lower part is an inclined plane, and three female walls are repaired in layers, and a small Tibetan soldier hole is dug behind the female wall (to avoid the rain in rainy days). Enemy soldiers in close proximity will be killed by cross-fire from arquebuses in three directions; Moreover, there are three soldiers hidden in the hidden soldiers behind each wall, and they take turns firing to ensure the frequency of fire.

There is a small fort and a sentinel defense system within a radius of ten miles, and fireworks, Kong Ming lanterns, wolf smoke, and drums are used as signals for early warning; When encountering a small group of men and horses, they will send troops to exterminate them with a small fort, and when they encounter a large group of men and horses, they will give a signal and run away on horseback.

There is a water gate on the south side of the fort, a ditch river is connected with the Yellow River, and a wharf is set up in the fort.

……

After reading the drawings, all the soldiers were already waiting in the tents of the Chinese army.

They have one more thing to discuss today.

At this time, there were already soldiers who came forward to speak.

And then there are other people's opinions.

In the tent, several sand tables were placed.

On the sand table, the topography of the northwest is clear at a glance.

Li Chuyun looked at these sand tables, and was thinking in his heart.

At this time, it was mentioned that the Yellow River flowed north-south in the eastern part of Shaanxi, and now the Song Army's Western Route Army is taking this road.

Their early destination was the confluence of the Wuding River and the Yellow River.

…… The lower reaches of the Wuding River that flows into the Yellow River already belonged to the Pingxia regime.

The upper reaches of the Wuding River flow in an east-west direction, and the downstream flow in a north-south direction. The downstream section is on the west side of the Yellow River.

Going up the Wuding River, you will soon reach Suizhou: a city occupied by the Xia Zhou regime.

Suizhou is at the confluence of the Dali River and the Wuding River.

Continuing up the Wuding River, another city where the river meets: Yinzhou.

Ginju is roughly part of what the ministers call the "Yokoyama region".

The Hengshan area is the main agricultural and animal husbandry area in Pingxia, and after the party obtained this ravine-rich area, its strength increased a lot.

And this time, Song Jun also has to beware of party members.

If, after going north to reinforce the Eastern Route Army, these party members suddenly became in disorder, that situation would be very dangerous.

Now that the Song army has uprooted a Liao military town, it still needs to be careful.

The Wuding River flows from Yinzhou upstream to the east and west.

Further upstream is the center of the party: Xiazhou.

The Great Xia State of the Jin Dynasty built the "Tongwan City" as the capital, which was the city built at that time. It is on the north bank of the Wuding River and should belong to the plateau area.

"What does Your Majesty mean?"

"Although the Northwest Party is subordinate to our imperial court, it has always been a disaster, this time take advantage of this opportunity to go north, you might as well do it directly, as long as our army controls the Yellow River, we can guarantee foreign aid from Wudingbao. The imperial court had already designed the drawings and ordered the Tokyo Military Department to equip the inland water division with artillery to ensure the seizure of the Yellow River water rights if necessary...... Although the party does not have a water division. ”

"How?"

"Naturally, it's pretending to be Liao."
