My surname is Wang, my neighbor Wu Dalang

The dispute between Yue Fei and Guan Sheng is obviously not unique to today.

At first, Yue Fei wanted to cut off the water source of Youzhou.

However, news from within Youzhou shows that there is a lot of water stored in Youzhou city, and every household has a deep well. Simply cutting off the water source may not be able to truly cut off the drinking water in the city.

So Guan Sheng proposed to release rotten poison in the diversion canal.

Although the Jin people may be on guard, but if people don't drink the water from the aqueduct, livestock must drink, right?The weather is so hot, the soldiers and civilians in the city can't help washing and bathing, right?
As long as the water resources entering the city are polluted, there will be chaos in the city.

At least, it will further exacerbate the fluctuations in the hearts of the soldiers and civilians in the city.

But Yue Fei believed that this move would harm the innocent people in the city.

Yue Fei was the main general, but he refused, and Guan Sheng had no choice.

Seeing the discord between the two, Wang Lin frowned and said calmly: "Okay, don't argue. Let me think about it again."

In fact, Wang Lin knew that Guan Sheng's strategy was in the best interest of the Yan army.

You must know that hundreds of thousands of troops besieged Youzhou, and the daily consumption of food, grass and luggage was not a small amount, and these were all vain money.

Moreover, from the standpoint of Dayan, the people of Youzhou, who had been ruled by Liao and Jin people for hundreds of years, could not be regarded as Han people in the true sense.

Their sense of belonging and identity to the Han Dynasty in the Central Plains can be said to be zero.

But after all, Wang Lin is a time traveler who was born in the new society, grew up under the red flag, and received modern humanistic education. He felt that doing so lacked basic humanitarianism.

The key is that the weather is hot now, and the method of poisoning can easily cause a plague in the city.And once it spreads, the Yan army outside the city may not be spared.

But if you want to forcibly attack the city, more people will die.

Such a big city, with [-] powerful Jin troops in the city, and the Yan army storming, can the casualties be so small?
Song Taizong's two Northern Expeditions after he ascended the throne actually reached the city of Youzhou.

In the end, the Song army exhausted its advantages under the city and was defeated by the Liao Kingdom.

Outside the Jiande Gate of Youzhou, Wang Lin led a team of brocade-clothed iron cavalry galloping from west to east. He led the team immediately in front of the camp of the Yan army here, and behind the wide moat of Youzhou.

In the past two days, he ran around Youzhou City.

If such a fortified city is to be attacked by force, it needs to invest a huge amount of troops.

And once a siege is launched, the casualties are even more difficult to count. Wang Lin is not willing to let the army suffer unnecessary casualties on the premise that Youzhou has become an isolated city and will be taken sooner or later.

Now is the summer grain harvest season.

At least half of the Dayan army and horses besieging the city were busy harvesting summer grain in the fields of Youzhou.

Yan Qing bowed immediately and said: "Your Majesty, I believe that Youzhou is vast and strong, if we attack by force, our army will suffer heavy casualties.

It is better to temporarily order the Sifang camp to mainly harass the city with catapults, and immediately cut off the water source of Youzhou, fill up the moat, and prepare for the next step to attack the city. "

"The golden man has no way to retreat. He is already a turtle in a urn, and the morale of the army will inevitably fluctuate. If our army harasses everywhere again and again, there will be civil strife in the city."

Wang Lin nodded slightly: "It's possible. Not only that, Xiao Yi, look over there."

Wang Lin raised his finger and pointed to the high mountain near Youzhou.

This is a branch of Yanshan Mountain, called Langshan Mountain, and the shadow of Youzhou City is built against this mountain.

In the past, the nobles of the Liao people built many pavilions, thatched cottages, and villas in this mountain, which were the places for scholars and nobles in the city to climb high for spring outings, close to Guihua Gate.

Wang Lin took out a blueprint from his pocket and said, "Xiao Yi, order the craftsmen in the army to quickly make the catapult machine according to the drawing. If you don't know anything, you can ask me... Then order thousands of soldiers to climb this mountain to occupy the high point, Build the sling..."

Yan Qing was startled for a moment, then smiled bitterly and said, "Your Majesty, the trebuchet is very huge, and it may be very difficult to carry it up the mountain."

Wang Lin smiled slightly: "This small trebuchet of mine can be made into various parts at the foot of the mountain, with a mortise and tenon structure, and then transported up the mountain to be easily assembled.

Xiao Yi, you see, this mountain is the most miles away from Youzhou. The Khitan people probably hollowed out half of this mountain and incorporated it into the city, leaving only this half of the mountain to enjoy the scenery.

If dozens of catapults are installed on the high place of this mountain, and soldiers are sent to dig the mountain to fetch stones, and they project huge boulders whizzing down from the heights every day, with one wave every day, over time, the Jin people will surely collapse without fighting. "

……

In the absence of heavy artillery, the trebuchet is no different from a siege weapon.

The large-scale trebuchets widely used in the Yan army are the ones that Wang Lin had partially improved in Qingzhou in the past. The throwing distance is longer, and wheels are added to the bottom so that they can move around, and the horses are used as traction power.

Don't look at this as an improvement in local details, but for ancient warfare, the value it can produce is incalculable.

And the small trebuchet he proposed today is, in a word, a kind of catapult that can be loaded and disassembled with a mortise and tenon structure and cleverly uses the principle of leverage.

The advantage is that it can be moved, carried, loaded and unloaded, and more maneuverable; the disadvantage is that the projected amount is small and the degree of harm is low.

This also applies to the current situation.

Using the principle of leverage and physical inertia to project a large number of small stones into the city from a condescending height, forming dense rain, it is obviously impossible to really destroy the city defense of Youzhou, and it can only play a certain role in harassment.

There was no other way. With Wang Lin's limited knowledge of physics and engineering, he could only invent this kind of thing. Even if he was given time, he would not be able to invent things like airplanes, cannons, and steam engines.

It is not so easy to build a technology tree in ancient times.

Into the summer, the weather is getting hotter.

The hearts of the Jinjun in the city were even more fluctuating because of the hot weather.

Almost everyone knew that in Youzhou they were just waiting to die.

The golden men on the towers can see the bustling Yan army outside the city helping the local farmers harvest summer grain and sow autumn grain every day. On the official road at the far end, on the brighter and vast Hebei Great Plain, you can see more clearly There is an endless stream of merchants and pedestrians coming and going.

The current Youyan, even though Youzhou is still holding the golden army flag high, is actually surnamed Yan.

The golden man was in despair, and Youzhou was destined to be an isolated city.

In all parts of Yanyun, the Yan people have begun to send officials to take over the military affairs of the states, and at the same time, they have begun to immigrate to Youyan in large numbers to cultivate fields.

Wanyan Loushi led all the generals and Wanyan Zonghan and Wanyan Zongwang who were in the city climbed to the tower, and their eyes coincidently turned to the big banner with dragon pattern flying high in the far end, which was the Xingyuan of Emperor Dayan Wang Lin.

Wang Lin's emperor Xingyuan here undoubtedly means that the people of Yan have won the entire Seven Youyan Prefectures.

Wanyan Loushi's face was gloomy.

He didn't believe that Wang Lin could kill Wanyan Zongpan's 20 troops with his own bravery. The only possibility was that Wu Qimai and Wanyan Zongpan's father and son jointly sold You Yan and his [-] gold army to the Yan Kingdom.

At this point, Pu Luhu's troops had mutinied and fought among themselves, and most of the troops retreated to the mainland of the Kingdom of Jin.

According to Wanyan Zongwang's meaning, instead of sitting and waiting for death, it is better to abandon the city, lead [-] cavalry to fight to the death, rush out of a gap desperately, and fight back outside the pass, maybe there is still a glimmer of life.

But Wanyan Loushi knew very well that if they defended the city, they would still be able to survive for half a year because there was plenty of food in the city.In order to ensure the supply of military rations, he has ordered the rations of the people in the city to be halved.

But if he leads an army to break through, he will seek his own death and seek a quick death.

In order to prevent a mutiny in Youzhou similar to Puluhu's troops in Jizhou, Wanyan Loushi directly deprived Aguda of the authority to command the troops.

Now people like Wanyan Zongwang are actually confined in Youzhou.

Suddenly, on the blue sky, there were overwhelming stones whistling like a rain curtain, and the Yan army in all directions launched hundreds of trebuchets at the same time.

Stone attack, this is not the first time.

Wanyan Loushi was not flustered, and indifferently issued a military order for the entire army to retreat in an orderly manner.

Although the soldiers of the Jin army hid under the cover of fortresses or trenches and stone walls, Wanyan Loushi did not think that the Yan army could destroy Youzhou's city defenses with this little throwing of stones, but the rain of stones that passed by like locusts poured down. In the end, after all, the city of Youzhou was smashed again, and a person was turned on his back, crying ghosts and wolves.

Many houses were destroyed.

Although the casualties in the city were not large, the harassment and the resulting negative impact were enormous.

Yan Jun seemed to be walking his dog for fun. He came to such a wave or two or three waves every day from time to time, and then died down.

Come on suddenly, take a break when it's over.

The four sides of the city defenses may be attacked by stone bombs, and in the air, the rain of stones falling from the Langshan Mountain on the shaded side of the city falls on the noble area in the city, which is also the residence of the general of the Jin Army.

Sometimes during the day, sometimes at night, and sometimes at dawn, the Yan army on Langshan used gravel rain attacks as a means of harassment, without any rules at all, which made the people of Youzhou panic.

What's more terrible is that the Yan army began to cut off the water source in the city and fill up the moat.

This made the soldiers and civilians in the city very nervous, almost going crazy, but they didn't know when the Yan army would attack the city.

……

Time flies, and soon it will be the end of July in the second year of Dayan Fuxing.

Since the siege of Youzhou in March, the Yan army has not launched a real siege.However, since last month, the rock-throwing and raining raids launched from time to time every day, which are unshakable but have been launched from time to time, have been extremely colorful and brilliant.

The sun was shining brightly, and the city was burning like fire.

In the city of Youzhou, which had been cut off from the water source, the Jinjun soldiers and Youzhou people who were harassed by the harassing psychological warfare of the hurling stone rain and nearly collapsed had exhausted and manic expressions on their faces.

However, in the Yan Army camp outside the city, there were laughter and laughter.

Except for the troops on guard in rounds, most of the Yan army avoided the deeper foothills and shaded places.

Suddenly the sky was overcast and there was a strong wind.The people of Youzhou in the city were overjoyed, and they rushed out of their residences and onto the streets, looking up at the sky of lightning and thunder.

The torrential rain fell instantly.

This is the first rain in Youzhou since the beginning of summer.

Inside the emperor's courtyard, Wang Lin finished eating a piece of iced watermelon, and Wanyan Wulu, who was squatting beside him and lowered his head, was also eating the watermelon with an incomparably satisfied look on his pretty face.

In the scorching heat, the emperor was able to create ice out of thin air. In Wanyan Wulu's view, it was almost like a miracle.

Seeing the emperor leaving the tent with his sword in hand, Wanyan Wulu quickly wiped his mouth and chased after him.
