The wind is sunny, sunny and cloudy, and the sun shines on the earth. After the flood is removed, the muddy ground is hot. The land that could have been trapped in horse hooves a few days ago has returned to its hardness.

A soldier looked up at the sky, reached out to wipe the sweat beads on his forehead, then lowered his head and spitted on his left and right palms, then held the long handle of the wooden hammer and swung it hard.

With a "bang", he smashed the mallet at a mechanism on the ground in front of him. After a click, the mechanism was unlocked. The heavy counterweight block not far from the soldier's head suddenly sank, causing the connected artillery rod to rotate around the axis.

One end of the gun rod was carried down by a counterweight, and the other end suddenly raised, throwing the heavy stones on the cable belt forward.

The stone weighing 60 kilograms was clearly angular, and it drew a graceful arc in the air and fell to the city below. It hit the battle shed on the city wall with a "bang", stirring up a burst of dust.

"The test shot is completed, fire the cannon!!!"

The shouts came one after another, and the trenchers like forests began to move one after another. With the creaking sound, huge rocks were thrown out, falling down to the head of Xuanhu City two hundred steps away like a stone rain in the sky.

After several years of actual combat, Zhou Jun's use of scattering machines has reached a perfect level, and the corresponding tactics have become more and more perfect. The skilled artillery soldiers can even use scattering machines to achieve the effect of "first hit" on the city wall without even testing.

Years of practical experience have brought good results to the first round of shooting. Most of the stones thrown by the trencher in the first round hit the Xuanhu City Wall or the high barrier in front of the city wall.

The place where the stones hit was dusty. There were also catapults in Xuanhu City that shot stones outward, but the number was at a disadvantage, because there were limited open spaces in the city, so so many catapults could not be shipped.

Not to mention that there was a circle of trenchers outside Xuanhu City at this time, throwing stones from the city from all directions. If the trenchers in the city counterattacked around each other, the number of stones they threw was even rarer.

One mile north of Xuanhu City, Prime Minister Yuchi Dun stood on the mound with a thousand-mile mirror in his hand and observed his siege. Seeing the first round of projectiles from the official army entering the city outside the city, he nodded with satisfaction.

Previously, in order to reduce casualties of soldiers and save thunder, he adopted a water strategy. As a result, the water attack failed one after another. Not only did he not only have no results in battle, but he also wasted time.

If you delay like this, it will affect the overall strategy. Therefore, Yuchi Dun made a quick decision to break the dike and release the water, and decided to use a catapult to attack the city directly. Even if the casualties and expenses are greater, he should conquer Xuanhu as soon as possible.

When the government army built long encirclements and built river dams, it did not stop building trenchers. Therefore, when the trench was released and the ground outside the Xuanhu City was dry, the government army could immediately invest a large number of counterweight trenchers to attack the city.

The trenchers they built were all on four wheels and could reach a distance of three to four hundred steps from Xuanhu, then quickly advance to the launch position, and then launch an attack on Xuanhu.

More than a hundred trenchers consumed a lot of wood, and the required stones were all the result of the efforts of the prefectures and counties in the upper reaches of Rushui, not to mention the powerful thunder. How long can the hanghu last under the day and night ejection of the trenchers?

But this is too much cost.

As the prime minister of the military commander of China and abroad, Yuchi Dun had many staff members to handle various affairs. He only needed to take overall charge and make key decisions. However, it was precisely because he sat in that position that he knew more and more thoroughly than others.

The catapulting machine shot a thunder and siege the city, which is indeed very powerful, but the problem that accompanies the problem is that the demand for gunpowder has increased dramatically. No one knows what the formula of gunpowder is. Yuchi Dun knows that it is not difficult to match gunpowder, but if you want to match too much, it is really difficult.

Only charcoal, sulfur and nitrate are needed to match gunpowder, and charcoal can be obtained at any time. When it comes to sulfur and nitrate, the vast land of Zhou Kingdom is not impossible to obtain, but it is just that it is urgent that it cannot obtain enough large-scale use.

In a siege battle, if the catapults shoot all the sky-bombing thunder, they can break through the city quickly, but this consumes a huge amount of gunpowder. There are so many enemy cities, so you can't use sky-bombing thunder every time you attack a city.

Yuchi Dun now masters the configuration of gunpowder and the production of thunder, so he knows that the annual output of thunder in the imperial court is limited and cannot be used unlimitedly on the battlefield.

Therefore, when attacking Xuanhu, the trencher was mixed with stones, fireballs and sky-bombing thunder were used. If you throw the sky-bombing thunder desperately as soon as you come up, a trencher threw 50 kilograms of sky-bombing thunder at a time, and a hundred trenchers would consume 5,000 kilograms of sky-bombing thunder in one round.

If you throw ten rounds, 50,000 jin, if you keep sending out the thunder day and night for more than ten days, the number of thunder in the army will be at its bottom. Even if you take down Xuanhu, how can you attack Fangcheng?

A clever wife cannot cook without rice. Yuchi Dun is helpless about the limited production of gunpowder, so this time he attacked Xuanhu, and the sky thunder could save as much as possible. He arranged people to prepare early, and with the help of the Rushui water transportation, he transported a large number of stones from the upstream prefectures and counties to prepare for the need to attack the city.

There is a flat mountain around Xuanhu, and there are no stone mountains. It is difficult to collect large quantities of stones weighing dozens of kilograms. However, this problem is no longer a problem. The key is that Xuanhu City Wall seems to be very resistant to smashing.

Yuchi Dun commanded many siege battles and had great power against the stone-capping machine. However, the Xuanhu City Wall and the high towers outside the wall were more solid than he expected.

At this time, the official army's trencher had finished the fifth round of projectiles, and the hit rate was roughly not low, but the Xuanhu City Wall and the high towers outside the wall were generally intact, and there was no obvious sign of collapse.

Of course, this was just the first day when he first attacked the city directly. Yuchi Dun did not expect to break through the Xuanhu City Wall on the morning of the first day. However, he witnessed the battle with his own eyes and always felt that the defense of Xuanhu City was stronger than he thought.

The battle shed on the top of the city was directly hit by a stone weighing dozens of kilograms, which only caused a burst of dust, and then it was still safe and sound. Even though the soil barrier that defended the city had been soaked in water before, there was no sign of collapse even if it was hit by the stone.

Yuchi Dun could guess that Yu Wenwen, who was guarding Xuanhu, made great efforts to strengthen the city defense. He once heard that there was a building material in Shannan called "cement", which seemed to be very effective in strengthening the city wall.

Now it seems that the Xuanhu City Wall is probably much stronger than before, as for the "cement"...

No matter how hard the cement is, it cannot be harder than the stone. It is a city wall made of stone, and it cannot withstand the attack of the catapult!!

Yuchi Dun thought so, put down the Qianli Mile Mile and said to the general beside him: "It's time to start."

"The last general takes the order."

The general sent a commander to send commanders to various siege positions, and began to implement a tactic.

The smelly carriages slowly came to the catapult positions everywhere. The chariots were loaded with rotten and smelly corpses, which were cattle, sheep and other livestock that had died of plague. Some of them were killed directly, and the corpses of rotten livestock that were exposed to the sun for several days.

The rotten corpses, which were flowing with pus, emitting fishy smell, and many flies were wrapped in white cloth. After unloading the truck, they were loaded with a rope for a catapult. Even with masks, the artillery soldiers were still furious by the stench.

After finally getting ready, the burly soldier swung the mallet and smashed it at the machine. The cannon rod of the catapult turned, throwing rotten corpses to the Xuanhu City in front of him.

When siege, use a catapult to shoot rotten livestock corpses into the city. After the corpse lands, the remains are everywhere. The rotten meat and pus splashed open, which can pollute the water, food, and houses in the city. After ten days and half a month, a plague is very likely to break out in the city.

This tactic appeared during the battle against Sui, but this tactic hurts the world. Only with the consent of the commander, will the generals dare to let go and implement it.

Even though the body had been thrown out, the stinking smell still permeated the catapult position. The soldiers covered their noses and looked at Xuanhu with their eyes full of pity: Good, good, you should die sooner or be reborn soon!

......

On the ground, a large pool of blood and blood splashed on the ground in a splattered shape, and smelly wreckage was everywhere. Many soldiers wearing white robes, hats and masks stepped forward and gathered these things with wooden rakes.

The pigskin boots creaked on the smelly things. The soldiers carefully collected the wreckage into the dustpan, then poured it into a cart. Someone took a shovel and shoveled the soil on the ground contaminated by the smelly things and shoveled away the floating soil on the ground contaminated by the smelly things.

As soon as the shovel was halfway through, the horn sounded, and it was the soldiers on the top of the city who were warning - a new round of enemy launches was coming, and the soldiers who were cleaning the ground quickly hid in the bunker nearby, and soon "bang bang" sounded one after another.

It was the sound of the stones thrown by the trencher hitting the ground, bunkers, and city walls, and the rocks fell with fireballs and more rotten corpses.

The ground that had just been cleaned up was once again polluted by smelly wreckage, and even some sandbags were hit by corpses. The smelly flesh and blood were everywhere. The soldiers complained when they saw this, and then they entered a new round of "big cleaning".

This is their responsibility, responsible for cleaning up all the objects thrown into the city by the enemy. The stones must be carried away and thrown out with a tit-for-tat; after the fireball falls, it must be extinguished immediately to avoid igniting the buildings in the city.

Before the war, Shangguan had already ordered them to prepare and to clean up the rotten corpses thrown in by the enemy, because this thing could cause a plague in the city.

In a bunker, the city-sailing Wang Yuwen Wen was eating a piece of cooked cake with relish. It was noon and it was meal time, so even though the scene was stinking, Yuwen Wen was still eating the cooked cake as if nothing had happened.

It is still the kind with meat floss, and the color and appearance of the meat floss shreds are similar to the pile of rotten wreckage in front of you.

"The cakes are not enough, the meat floss is just a little bit, and it is not enough to plug into the teeth. Which one is the one who makes it? Write it down and settle the score with them after you go back!"

"The unscrupulous businessman! He actually dares to cut corners on military supplies. Do you think I dare not kill anyone?"

Yuwen Wen cursed, and Zhang Yu, who was beside him, leaned closer and said, "Just just now, when the Langzhu and Wang Zhanjun were talking, a lot of the meat in the cook cakes had loosened and on the ground..."

"Hmm? Is that true?"

"Yes, the man."

Yuwen Wen looked at the ground, but there was a loose meat scattered under his feet. After coughing dryly, he finished the pancake in his hand. He looked at the fishy smell outside and felt a little sad.

With the widespread use of counterweight catapults on the battlefield, a "biochemical attack" will appear sooner or later. This is a tactic that has indeed appeared in history, accompanied by the Mongolian army sweeping over the Eurasian continent.

Yuwen Wen asked the counterweight catapult (Ruihui cannon) to appear in advance, so the tactic of shooting rotten corpses into the city to create plague would appear in advance. Now, he has tasted the consequences of changing the timeline.

Fortunately, it was not bombarded by enemy artillery.

Yuwen Wen thought so, and the footsteps sounded. Wang Jun, the military officer in the record room, walked in with a note.

"How is it, what's going on?"

"Back to the king, it's over..." Wang Jun looked at the pocket watch, then looked at the note he had just obtained, and continued: "As of half an hour ago, at least eighty-five rotten corpses had fallen in the city, and now all have been removed."

“Has the well been affected?”

"No, all the wells in the city have taken protective measures."

"Very good." Yuwen Wen nodded and looked at the busy soldiers outside the bunker. "As expected, they threw rotten corpses into the city, trying to trigger the plague."

Wang Yun followed Yuwen Wen's gaze and looked at the fishy smell outside. The smell made him feel a little uncomfortable in his stomach. There was nothing to do with the death of marching and fighting, and the smell of corpses was common, but it was the first time he had seen such a fishy rotten corpse.

"Let's go, get into the city."

Yuwen Wen turned and left, walking towards the east of the city along the "traffic trench" with protection at the top. Wang Xu followed closely behind. Seeing that Zhang Yu, the lieutenant of the royal palace, handed over a pancake, he waved his hand and signaled not to use it.

"Are you full?"

"Back to the king, I have a stomach upset and can't take it for the time being."

Facing Yuwen Wen's question, Wang Jun decided to answer truthfully. He had been a doctor for a long time and was really not used to eating while smelling the stench.

"It's okay, just get used to it."

Yuwen Wen said as he walked, and then the topic changed: "I didn't expect that they shot the rotten corpse into the city so quickly. It seems that they are really anxious."

"King, the more anxious they are, the more stable our army will be. We must not attack easily and take advantage of it..."

The two of them were discussing the matter of defending the city. Before, Yuwen Wen asked Wang Jun to give his opinions on the strategy of defending the city. One of the doubts raised by Wang Jun was how to deal with the enemy's destruction corpses thrown into the city.

The tactics of rotten corpses siege in the city are incredible, but Wang Nai could understand the interests. He suggested that the rotten corpses be processed in a concentrated manner and burn them with fire instead of sprinkling quicklime on each rotten corpse for "disinfection".

The quicklime reserves in the city are limited, so save as much as possible.

"Save as much as you can. These four words are correct. The enemy has not been willing to invest too much thunder in the sky. It seems that the stock is tight, which really disappoints me."

Yuwen Wen climbed up the steps and said as he walked, suddenly a few muffled sounds came from above his head. The sandbag protective shed above the steps was shocked, as if something was hit on it.

After a moment, something rolled down the ceiling and rolled down the "stone guide groove".

It was a stone as big as a millstone. It should have been shot into the city by the enemy's catapult and hit the cover on the city. Then it rolled down and was blocked by the protective shed on the steps. If this were not the case, Yuwen Wen and others would have turned into a pool of meat paste.

Walking up to the city, Yu Wenwen looked around and found that the cover at the city was basically intact. He turned into a bunker, put on his earmuffs, and looked out through the observation port. The scene in front of him made him feel refreshed:

In the fields outside the city, dense trenched trenchers stood like forests, and countless soldiers surrounded them, working hard and busy like worker ants.

The tall trencher kept shooting objects at Xuanhu, including stones, fireballs, and corpses. Not long after Yu Wenwen climbed to the city, the explosion began to sound densely, and the fire at the head of Xuanhu was shining with black smoke.

That was when the other party began to throw thunder and storm was coming, and it would never subside in a short period of time.

The explosion was getting more and more intense. Yuwen Wen was using a thousand-mile mirror to observe the situation outside the city. Suddenly, a dull sound came from his ear, as if something was hitting the side. Before the people in the bunker could react, a loud bang made Yuwen Wen feel that the world was quiet.

The entire bunker was hit by a wave of air, and a little mud fell from the ceiling. Yuwen Wen's hands holding the inner wall of the bunker could feel the trembling of the bunker and the solidity of the bunker.

A sky-burning thunder exploded not far outside the bunker where he was, but the power of black gunpowder was never as powerful as explosives. The structure and shape of the city cover built by the Anzhou Army were optimized after countless trials.

Even if a thunder that weighs dozens of kilograms is detonated on the roof, it cannot harm the people in the bunker, and the stones shot by the catapult are not good.

This is a cross-age defensive fortification. Its opponent is explosives rather than black gunpowder. Its material mixed bunker is optimized to the maximum extent, and it cannot be pried open by a mere omnidirectional explosion.

Looking at the enemy troops outside the city, thinking about the bloody siege that would inevitably break out sooner or later, Yuwen Wen felt his blood was boiling. He had made complete preparations and was waiting for the other party to fill in the lives.

Even though the Xuanhu at this time was like a lonely boat sailing on the storm sea, Yu Wenwen was not afraid. When he thought of that sentence, he couldn't help but mutter to himself:
Chapter completed!
