In the water, a steamboat berthed on the north shore, and several large pipes extend into the water on the side of the river center. The boat-borne water pump keeps pumping water, pumping the river water onto the boat, and then transporting it to the shore through the hose.

On the shore is a large courtyard surrounded by wooden fences. There are several large boilers in the yard that are boiling water. The water from the pumping boat is used to supply the military camp.

A military camp of several miles is not far away, close to the water, and a large dock has been built on the shore to allow ships to transport personnel and supplies.

One mile northeast of the military camp is Pyongyang City, the capital of Goguryeo, and at this time the city of Pyongyang has turned into a sea of ​​fire.

The burning flames illuminated the eyes of soldiers from the peripheral army outside the city and also illuminated the eyes of King Yu and Wen Weimin of Wei. He looked at the burning Pyongyang without any expression on his face.

The army set out from Huangchenggang, Laizhou, and conquered Pyongyang in less than a month. This speed is worth pride, but nothing to be proud of: Pyongyang City is just an empty city, and the Goguryeo army did not resist tenaciously along the way.

Information shows that when Zhou's army crossed the sea and attacked the harbor at the mouth of the ridge of the ridge, Goguryeo's monarchs and ministers firmly implemented the strategy of strengthening the walls and clearing the fields, moving the people and livestock along the ridge, and then setting fire to the villages.

Not only are the villages, forts and cities in various places, but also the capital of Pyongyang, which is the same.

When the Zhou army pioneer arrived in Pyongyang, he found that the city was full of ruins and smelly animals everywhere, even the wells were no exception.

A large number of flies gathered on these corpses, making the entire Pyongyang City look like a "fly city". When people walk in it, dense flies will fly over and fall on them, as if they have changed into clothes.

The military and civilians of Goguryeo in Pyongyang and the surrounding Goguryeo have all retreated to the southeast mountains, where there are many mountain cities and stockpiled a large amount of food, which is enough for these people to hide in the mountains and confront the Zhou army for a long time.

Therefore, when the Zhou army marched towards Pyongyang along the river along the river, they had never fought any war. Instead, the obstacles accumulated in the river blocked the speed of the Zhou army's fleet.

Now, although Yuwen Weining, who is outside Pyongyang City, has sent good news to the country, she does not have much joy in her heart.

Because the main force of the enemy is intact, if one side wants to fight it, he has to gamble the mountain city in the mountains and compete for one mountain after another.

Yuwen Weining looked at the burning city of Pyongyang, and after a moment, he turned around and walked towards the military camp. The enemy's methods were extremely vicious and turned Pyongyang into a source of plague, so he could only burn it out and burn all the ghosts and monsters to clean up.

The uncleanness on the ground can be burned, but the uncleanness in the water can only be cleaned by another method, that is, filter the water and boil it.

The uncleanness in the boiling water that is invisible to the naked eye has become clean after high temperature treatment.

Yuwen Weining came to the camp and came to the water supply area. He looked at the tall water storage tanks, the iron pipes connected to the boiler room, the rows of drainage throats, and the rows of bathhouses that provide hot water for a limited time. He was very satisfied.

A mature centralized water supply system can provide clean drinking water to tens of thousands of soldiers when the water source (river) is contaminated by rotten corpses. Therefore, the behavior of the Goguryeo army polluting river water upstream of the water is equivalent to in vain.

The other party thought that sank a large number of animal corpses that began to decay into bamboo cages and sank to the bottom of the river, which would affect the drinking water hygiene in the downstream areas for a long time, which was ridiculous.

Turning to the Central Army tent, Yuwen Weining looked at the busy assistants who were divided into several groups, sat in his own position, and listened to the assistants to report the current progress.

The first thing is that the centralized water supply system is operating normally, and the loading and unloading capacity of the wharf reaches 60% of the design capacity. A large amount of materials arrive here, including sufficient coal, which can ensure the operation of the water supply system and the use of inland gunships.

However, it is not possible to rely solely on coal-fired shipping, because there are many storms on the sea in summer and autumn, and shipping will be greatly affected by the sea, so local materials must be used.

Fortunately, Goguryeo has been mining coal for more than ten years, and handing it over to Zhou Guo with coal as "annual tribute". There are coal mines in Pyongyang area, and its location has long been controlled by Zhou Guo Guo. Now several professional coal mining teams are under the protection of the army to restore the mining of these coal mines.

In about another month, these mature mining coal mines will be able to resume production and supply coal with all their efforts.

The second thing is agricultural production: the wheat and rice seeds transported are already in place. Now it is late spring and early summer. The abandoned farmland has still had time to cultivate. The military farming team organized by the court has arrived and started farming with some soldiers.

The rice is planted in dry fields and rice is planted in paddy fields. The seedling planting method is used. The seedling greenhouse located next to the military camp has begun to cultivate seedlings. Several teams of trading companies are responsible for the seedling cultivation work and provide seedlings for abandoned paddy fields in the Wushui area.

The third thing is that the construction materials are in place one after another, and the construction team is ready. According to the scheduled plan, it is necessary to build a fortress in the plains around Pyongyang so that the army and the military farming team can support it.

We also need to build artillery towers to control important roads and support for fortresses, and gradually strengthen control over the surrounding areas of Pyongyang.

Then establish a defense line at the junction of the plain and the mountainous areas, strive to make the Goguryeo army "easy to enter the mountains and difficult to get out of the mountains", and protect the farming areas of the plains and ensure the agricultural harvest in autumn.

In short, everything is in accordance with the combat plan and is progressing smoothly. Before the arrival of the storm-prone season in summer and autumn, the march will initially gain a foothold in the Yushui and its surrounding plains, and the supply of materials will not be affected by the interruption of maritime transportation.

Let Goguryeo's "strengthening the walls and clearing the country" plan go bankrupt.

Yuwen Weining was very satisfied with the progress. Although the decisive battle he had been looking forward to did not start along the way, the opponent's actions were not in the slightest departure from his pre-war predictions, which made him very happy.

The court always had to take action against Goguryeo and recover the four counties of Han. So, what kind of countermeasures would Goguryeo, which suffered a great loss, faced with the Zhou army that was well-equipped and could cross the sea to attack in a steamboat at any time?

More than ten years ago, the Zhou army invaded Goguryeo's hinterland, as if they were in a state of no one. After suffering enough, they would definitely not fight head-on.

The Privy Council of the Secretariat predicted the war was that the opponent was very likely to adopt a strategy of strengthening the walls and clearing the fields, defending and counterattacking, and not fighting head-on with the main force of the Zhou army, and not fighting a decisive battle. Instead, he gave up the plains and burned the cities, forts, villages, and the soldiers and civilians hid in the mountains stretching in the northeast.

According to the investigation by the Ministry of Education, in the past ten years, Goguryeo has been building amidst mountains, expanding the mountain city, and constantly stocking up grain and grass.

If the Zhou army attacked, the Goguryeo army would hide in the mountains and rely on the terrain to fight attrition with the Zhou army, and drag it to the arrival of the sea storm-prone season in summer and autumn.

By then, the shipping route would be almost interrupted, causing the Zhou army's logistics to be in trouble.

Therefore, the Zhou army that invaded Goguryeo at the beginning of the year had been ineffective after fighting for half a year. The local farmland was abandoned since the beginning of the year, and could not harvest much food in the autumn, so the morale of the army was in chaos and the use of dull moves frequently. Then the time for the Goguryeo army to counterattack was arrived.

This strategy is helpless but effective for the Goguryeo side (relatively speaking). The other side has been building a new mountain city for more than ten years, preparing for a long-term confrontation. Therefore, once the war begins, Goguryeo is highly likely to be firm in the walls and clear the fields, and the military and civilians hide in the mountains.

Now, it is indeed the case.

In order to cause trouble to the Zhou army as much as possible, the other party not only gave up Pyongyang, but also turned Pyongyang into a source of plague, and wanted to pollute the water, causing a large number of Zhou army soldiers to get sick.

He also deliberately left behind some people with serious diseases, including some young women, in order to increase the probability of Zhou Jun's infection and plague outbreak.

However, all this has become empty talk with the full preparation of the Zhou army.

Yuwen Weining looked at the map with a relaxed expression.

If you have a strong wall and clear the country, I will take the lead in taking the initiative to resume agricultural production, establish strongholds, and operate Pyongyang and its surrounding areas.

The government army wanted to recover the former lands of the four counties of Han, so they would not leave this time. They fought wars and carried out construction. Although the investment would be huge, who made the dynasty rich?

Being rich is so willful.

Yuwen Weining thought about it and smiled slightly. He squatted in the Weishui Canyon last year and built a railway for a year. This year he took charge of the battle and flew eastward into the former land of the four counties of Han, and wanted to build a railway again.

The imperial court built the Xulai Railway and opened to traffic last year to improve the capacity of personnel and material transportation. In addition, steamships could send a large number of personnel and materials to the Haidong Peninsula in a short time after the war against Goguryeo.

Give the other party a big surprise: take the lead in the guest.

With waterways as pillars, railways as chains, artillery towers and fortresses as locks, the plains centered on Pyongyang are firmly locked and the mountains are blocked outside.

At the same time, a lot of manpower and material resources were invested to restore agriculture, mining production, and farm under the nose of the enemy.

Relying on its strong production capacity and transportation capacity, a large number of railway tracks, sleepers, and gravel were transported, and then, with Pyongyang as the center, the forts and artillery towers in key areas were connected by railways.

Yuwen Weining looked at the preliminary railway construction planning map and wanted to see what the expressions of the Goguryeo monarch and ministers after seeing the railway were like.

With the railway, there is a telegram line, forming a responsive "spider web". Any place where there is a turbulence, Pyongyang, located in the middle of the spider web, will respond in time.

The strongholds laid along the railway and the armored trains cruised on the railway will make the Goguryeo army approaching the railway come and go.

Then the other two marches divided their work and cooperated to eliminate the forces on the north and south wings of Goguryeo.

At that time, the Goguryeo ruler and minister who were hiding in the mountains waiting for defense and counterattack would find themselves like monkeys locked in cages, jumping up and down but having no choice.
