Yuan Jian always felt that these catapults looked a little different from what he had seen in Guangling before, but he didn't show any abnormalities on his face, and he didn't ask too much.

The difference is naturally huge!

Outside the cities of Qichun and Guangling, the use of throwing disaster relief food was only the previous "practice" torsion catapult.

In Hefei City, not far from Chaoxian County, the special team of the Ministry of Industry has been stationed, a shipload of parts manufactured by the Ministry of Shipbuilding, directly from the mouth of the river into the river, transported to the mouth of the Xukou, into Chaohu Lake, and finally unloaded in Chaoxian County, the Ministry of Engineering team will complete the final assembly here, as well as some of the technical content, easy to take local materials, but the final manufacture of bulky parts.

Now the twenty catapults in front of the military array of Baitu are all counterweight catapults, and the main design idea refers to the "Huihui Cannon" used by the Mongols during the battle of Xiangfan in the Song and Yuan dynasties in the later Song and Yuan dynasties - just listen to the name, it is a skill from the Western Regions, and the people of the Western Regions also invented it.

In May of the third year of Jian'an, because Yuan Yin refused to cooperate and ignored the people in the city who wanted to welcome Baitu, the Jiangdong army outside Hefei exchanged the relief food thrown every day for a stone bullet of more than 100 catties!

Yuan Yin also felt that today's Jiangdong Army was menacing, and some nervous Gu Jia climbed the tower and looked down on the military formation below on the city wall.

"Yuan thief poisoned Huainan, a place of wealth and happiness in the past, but now he is hungry all over the wilderness, and he eats with children, although Bai Mou started from the end of the micro, but he bears the expectations of the people......

Although you are an iron heart from the thief, but I still have the idea of benevolence in my heart, today if you take more than 100,000 people in the city as your thoughts, open the door to welcome us and other relief, you can still leave a good name in history, if you resist stubbornly, ignore the people of Hefei, Bai has to be on the heart of the sky, under the Li people, the day the city is broken, the first evil person will be cooked in Dingzhong, and the military and people of Hefei will eat together! Bai Tu shouted loudly under the city.

Yuan Yin also knew the reason for Bai Tu's ruthless behavior of changing the painless and pain-seeking persuasion of a few days ago, and today he suddenly became vicious, threatened to stew him as soon as he opened his mouth, and shared it with the whole city.

The dedication of Guangling and Qichun not only hit the morale of the Huainan Army and inspired Bai Tu's Jiangdong Army, but also made Bai Tu completely occupy the moral upper hand.

Yuan Yin had expected it before, and Bai Tu ...... I'm afraid I'm going to attack the city head-on!

After all, tens of thousands of people waded into drought-stricken Huainan, how could they do nothing?

But after hearing Bai Tu's threat...... Especially when the 30,000 elite soldiers outside shouted in unison, "Eat together, eat together", Yuan Yin was still nervous.

"White Picture! In the past, don't care about it, since you keep saying that for the sake of the common people, but now there is a drought in Huainan and Jiangdong, isn't it against the way of the benevolent to move troops at this time? Yuan Yin shouted stubbornly.

"Ridiculous! I, the three million people of Jiangdong, worked together, worried about the worries of the Huainan compatriots, anxious about the anxieties of the Huainan compatriots, cut down on food and clothing, and received millions of stones of relief food, and wanted to overcome the difficulties with the people of Huainan, but for their own selfish desires, they actually blocked it, as if Yuan Lin and his ilk, in order to discredit Jiangdong, actually did such a thing as poisoning the people......

Soldiers! Can you tolerate this happening? Can you watch the good intentions of Jiangdong's fathers and elders being wasted, and the innocent people of Huainan being harmed by Yuan Wei? Bai Tu asked in a loud voice.

At this time, among the 30,000 Jiangdong Army, there were nearly 5,000 "living people", and the proportion was very high-Baitu's Protector Shrine and military treatment increased the enthusiasm of the army, and the number of grassroots army commanders and even chiefs became more and more abundant.

In the world of Chengji, even if the princes are reckless, they can only increase the proportion of manpower extracted, and rarely force strong men - because the living people in the army are at least the captains, or even like the Huainan Army, because there are too many manpower extracted, and they are not popular with the people, and the living people join the army even longer.

In this case, if you force a strong man, once you defect in battle, it may cause chaos on the battlefield.

In contrast, Baitu's Jiangdong Army, although the proportion of military service is small, is correspondingly ...... The captain is almost complete!

Moreover, Bai Tu specially set up a propaganda team in the army, the prototype of which was the persuasion team set up by Bai Turang Rites before, but the officials and officials who were delegated to the army by the Ministry of Rites were too ungrounded, and all kinds of time to talk about big truths even became a burden for grassroots officers.

After Zhang Liao reported this to Bai Tu, Bai Tu also made adjustments, and replaced it with a propaganda team that was more able to get along with the officers and was even selected from among the officers, without so many annoying reasons, and focused on the "war mobilization" before each battle.

For example, at this time, the Jiangdong Army understood that they were fighting for the people of Huainan!

Think about the old and young in the family, and the people who cut down on food and clothing followed the relief food, isn't it just to help the people of Huainan?

Every time I think of this, the officers and men in the army are honored......

However, the enemy was so mad that he didn't let them hand over the relief food to the people of Huainan, how could there be such a bad person?

The heart of hatred for the same enemy rose in the Jiangdong army - the lord is right, this "benevolence" was made up by our Jiangdong fathers and elders together, and it must be sent out!

Understanding the meaning of war not only helps to improve morale, but also restricts military discipline.

After Bai Tu finished shouting, he retreated to the high earth platform built behind the formation.

As the "boss", Bai Tu is only responsible for the command of the grand strategy, and the specific command is in the hands of Lu Bu.

Accompanied by the personal soldiers beside Bai Tu, under the command of Bai Tu, the flag was raised, and Ding Feng, the pioneer general in the vanguard army, shouted: "Go to the white cannon!" ”

White Gong Cannon...... Bai Tu also felt that the name was a little awkward, in short, now there are twenty white cannons, and they are brushing against the Hefei city wall.

"L!"

Crunch squeak –

I saw that the short arm end of the throwing wall of the white cannon was pulled up by a group of soldiers with a winch - the weight at one end of the short arm was ten times that of the long arm end, although the long arm end of the lever principle was labor-saving, but under the huge weight gap, the normal short arm end was still below.

The winch also uses the principle of pulley, which lifts the weight of the short arm more labor-saving, and when one end of the long arm falls, a stone bullet of more than 100 catties is put into the bullet nest at the end of the long arm......

"Put!"

Under Ding Feng's order, the winch that originally maintained the end of the short arm was released, and under the weight of more than 1,000 catties, more than 100 catties of stone bullets were directly lifted, and because it was located on the side of the long arm of the lever, the lifting speed was extremely fast!

"Raise your shield and go straight ahead!" Yuan Yin also immediately ordered.

After all, there was "feeding" a few days ago, and Yuan Yin also knew what these were for.

Under the sound of wind and thunder, stone bullets of more than 100 catties flew towards Hefei City after being lifted to the highest point.

Most of them hit the city walls directly, but some of them just landed on the castle towers......

The "grain truck" a few days ago showed its magnificent side in front of Hefei City today!

There happened to be a stone bullet that hit the pro-soldier who was under Yuan Yin's order and was holding a heavy shield that seemed reliable.

Yuan Yin only heard a roar in his ears, and then there was one less soldier around him, and then he looked carefully...... The shattered shield, the shattered wood and stone armor, and the shattered pro-soldier are inseparable from each other.

"This, this ......" Yuan Yin couldn't help but be stunned for a while.

The white cannon under the city did not give Yuan Yin a chance to react, and after some adjustments, the second round of salvo came again!

The commissioning of the Baigong cannon, as well as the entourage of the Ministry of Engineering, was at this time correcting the angle of the turret and the height of the short arm according to the previous landing point......

Of course, although the standardized processing controls the difference between each white cannon within a very small range, because of the different wear and tear, and the use of hastily polished stone bullets, the weight, center of gravity, and even the shape of each stone bullet are different, and it is technically impossible to expect the white gun to be able to aim accurately.

There is no need for a precise fixed point, and at this time, under Ding Feng's order, the target to be calibrated is the middle of the opposite city wall.

There was another round of wind and thunder cannons, but this time there was no shot, "mistakenly" hitting" the defenders on the city tower, but ...... The defenders on the city wall clearly felt that the wall was shaking!

Although when the stone bullet hits, the city wall also flashes with a faint golden light, and some of the power is removed, but it is still immune.

The main target of the return cannon was never the defenders, but the city walls or the warships.

According to the records of the "Yuan History" of another world, this kind of return cannon "weighs 150 catties, is machine-fired, and the sound shocks the heavens and the earth, and all the hits are destroyed, and it is seven feet into the ground"......

It is also this kind of sharp weapon invented by the craftsmen of the Western Regions that drew an end to the last stage of the Song and Yuan dynasties in Xiangfan, nearly six years of offensive and defensive warfare, and the Song Dynasty was now out of vitality and lost the last opportunity to drag Yuan and Meng to death.

In the history of the "other world", the debut of the Huihui artillery broke through Fancheng, and Lu Wenhuan, who had been defending Xiangyang for nearly six years, had no choice but to go out of the city and surrender to the Yuan because he could not crack the offensive of the Huihui artillery and was forced by the Yuan army's massacre in Fancheng.

Later, the Huihui artillery also followed the offensive of the Yuan army, breaking the Yangtze River Water Army, breaking Tanzhou, and Jingjiang......

Of course, the return cannon is not invincible, no matter how it is optimized, its movement speed is extremely slow, even the heavy infantry cannot outrun, and can only be used for attack and defense in fixed positions.

As long as the military array is moved, returning to the artillery array is equivalent to finding an ancestor and a life for your own military array.

So at the end of the Yuan Dynasty, when the rebel armies from all walks of life were against the Yuan, they could no longer see this thing, and in the cavalry confrontation of Mingjin, the trebuchet was even more of a joke.

However, just as the Song army at the end of the Southern Song Dynasty could not engage the Mongols head-on and could only defend against the danger, did the Yuan army in Hefei dare to come down and fight with Lü Bu?

"Put!"

After the third round of white cannon roared out, the golden light on the city wall of Hefei was almost faint - most of this is due to the establishment of the Zhong family's "dynasty", so that all the walls in the country have added a layer of founding buff.

Otherwise, purely from the perspective of the people's hearts, the city wall of Hefei may not play such a big role.

Yuan Yin also knew that the defensive effect of the founding buff would probably not save him if it went on like this.

The power of this white cannon was beyond his expectations, and now although the Jiangdong Army has run out of stone shells after five rounds of salvo, it ......

Yuan Yin didn't clean up the surrounding stone sources before, that is to say, as long as it was simply repaired, the other party could replenish the stone bullets, and there was no point in continuing to wait for the city wall to collapse!
