The rumbling sound of the cannon instantly attracted everyone's attention, whether it was the Oda army, the Tokugawa army, or the Takeda army, those who were not entangled with the enemy couldn't help but look in the direction where the roar was coming from.

The three bigwigs, Oda Nobunaga, Takeda Shingen, and Tokugawa Ieyasu, were all in a state of pressure, so the three of them raised their heads and watched together.

When the cannonballs were still flying in mid-air and had not yet hit the head of Kotani Castle, the attitudes of the three people were different.

"Is this the 'big barrel' that has begun to become popular in Kyushu?" Tokugawa Ieyasu couldn't help but think as he watched the black cannonballs fly, "What is the use of a big iron ball flying towards the enemy?"

"This thing seems to be making the fire gun thicker and bigger...... It was still just a large bullet that came out. Oda Nobunaga couldn't help but spit out.

Takeda Shingen didn't say anything, his whole body was hidden in armor, and no one knew where he was looking or what he was thinking.

The three daimyo were not optimistic about the power of the large cylinder at first, but ...... When the shells landed on the head of Kotani, everything changed. The big black iron ball is not as simple as thickening and enlarging the firebolt, because the cannonballs fired by the cannon will explode, and the kinetic energy and impact contained in it are far from being comparable to the bullets of the firebolt.

The first part of Kotani Castle was instantly submerged in a cloud of gunpowder smoke and debris, and the castle defenders of the Asai family were swept down in an instant, and in the following time, the cannonballs fell one after another on the head of Kotani Castle, and each shell exploded. Each explosion swept a five-meter radius into a clearing.

After the two rounds of the flowering bullets, there were no soldiers of the Asai family standing as far as the naked eye could see, because the people in the city were already lying down in fright, and no one dared to stand on the city wall with swagger and enjoy the battle below.

Oda Nobutaga was taken aback: "It's amazing...... The bullets emitted by this large barrel can even explode, injuring a large number of people at once!"

Tokugawa Ieyasu also felt a chill in his vest: "My turtle pit." Can you withstand such an attack?"

Takeda Shingen's body shrouded in armor also raised his head in the direction of Kotani Castle, as if staring at the tragic situation on the castle head......

The three daimyo were almost at the same time. I was shocked by the terrifying power of the big tube.

Yi Yun laughed and said, "It's not over yet, change me to a solid bullet and play two more rounds!"

"Yes!"

The artillerymen gladly accepted the order. All fifty cannons began to replace solid shells......

Yi Yun waved his hand and said loudly: "The target of the solid bullet, lock it to the middle of the cliff for me, and ......bombard it hard."

"Lord Wang, what's the use of bombing the mountain cliff?" the artillerymen were puzzled.

Yi Yun laughed and said, "Don't ask me why, just carry out my orders!"

"Yes!"

The female artillerymen began to adjust the muzzle of the gun, pressing it down, and no longer aiming at Kotani Castle at the top of the mountain, but at the mountain...... As mentioned earlier, Kotani Castle was built on top of a mountain surrounded by cliffs on all sides. The sword-like mountain has become the most natural castle wall of Otani Castle, and it is 299 meters high, making it difficult to conquer.

At this time, Yiyun's artillerymen pressed the muzzle of the gun, and all of them aimed at the mountain at a height of about 150 meters.

"Fire!"

"Concentrate a little. Boom!"

Fifty cannons roared again, this time with all solid shells, and the black shells, with a huge impact, flew out of the muzzles and smashed hard against the smooth and steep mountain.

"Huh, why did you build the mountain wall?" Oda Nobunaga, Tokugawa Ieyasu, and Takeda Shingen couldn't help but look sideways.

Only a loud rumbling sound was heard, and a cloud of soot exploded on the cliff. The stones splashed, the mountain shook, and when the smoke of the first round of shelling cleared, everyone looked at it and saw that many huge potholes had been blasted out of the middle of the cliff, and many stones weighing 100 catties were separated from the mountain and rolled down along the mountain wall, with a huge sound. ...,

"Wow! The army of Kyushu Shou is in Bangshan?"

"Are they trying to knock this mountain down?"

"It's impossible!"

The Oda, Tokugawa, and Takeda armies at the foot of the mountain could all see that it was absolutely impossible for the mountain to be knocked down. But...... It's just because they're onlookers, and the Asai Army on the top of the mountain doesn't think so.

Since they are located on a 299-meter-high cliff, the height from the top of the mountain is enough to make people's heads dizzy, and on such a high mountain, although it is easy to defend and difficult to attack, you don't have to worry about the enemy rushing up, but you can't help but worry about whether you will fall to pieces.

Yi Yun's artillery fire was concentrated on the mountain, which didn't matter to the people at the foot of the mountain, but for the Asai army on the top of the mountain, it made them feel that the mountain under their feet was shaking, and the whole mountain seemed to be about to fall down at any time......

This is the so-called "psychological offensive," and the judges might as well think about it: If you were standing on a piece of flat ground and an earthquake suddenly occurred, would you be afraid? If you were standing on the balcony of a 50-story high-rise building and an earthquake suddenly occurred, would you be afraid? Obviously, people standing on 50 floors are far more afraid of earthquakes than people standing on flat ground.

The Asai army on the top of the mountain fell into a state of panic almost instantly!

"Oh my God, the army of Kyushu is going to knock down our mountain......"

"The mountains are shaking, the mountains are really shaking......"

"No, if this mountain falls, we will have to fall from a height of 299 meters......

"I'm going to be crushed......"

"I don't want to die like this!"

"Quick...... Hurry down the stairs of the mountain and go down the mountain......"

There was a panic among the samurai of the Asai family, and even the old man, Asai Nagamasa, couldn't sit still, and ran to the stairs down the mountain under the escort of a group of samurai.

It's a pity that Iyun had already guessed that they would take such an action, and immediately, another ferocious round of flowering bombs flew up, and the artillery fire covered the narrow mountain road completely, and a large group of samurai were bombarded to the ground, and the poor hundred-year-old man Asai Nagamasa only picked up a life and retreated to the city with a few samurai acting as meat shields.

"Wha!" Yi Yun smirked, he waved the command flag in his hand, and said loudly: "Stop shelling Kotani Castle, now turn the muzzle, and the artillery team will be divided into two halves, half aimed at the battlefield of the Oda Army and the Sanada family, and the other half will be aimed at the battlefield of the Tokugawa Army and the Takeda Army......"

"Yes!" the artillery team began to act, in fact, each female artilleryman was equipped with several assistants, and these assistants were responsible for carrying the cannons, or loading the guns, after Yiyun's order was given, the fifty artillery teams began to act, turned the cannons, and aimed at the battlefields on both sides.

Such a big move, of course, can't hide the Oda Army, Tokugawa Army, and Takeda Army, which have been watching the artillery position......

"Wow, they're going to bombard us with that terrible cannon?" exclaimed the Takeda soldiers.

"Won't you...... We're fighting with the Oda Army and the Tokugawa Army, and if the artillery bombards us, won't we involve their allies?"

"Implicating friendly forces is something that we who pay attention to righteousness can't do, but some ruthless people can do it......"

"Why don't we leave Oda and Tokugawa alone and go straight to the big barrel soldiers of the Kyushu Guard...... We are cavalry, and as long as we run with all our might, we can rush close without two rounds of big shots. ”

"Are you an idiot? I don't see anyone set up a rejection horse, and if I rush at them and don't break through the rejection in a short time, I will be in an embarrassing situation...... At this time, Oda and Tokugawa have regrouped their forces, and we will lose the battle......"

In fact, not only the people of the Takeda army were panicking, but also the people of the Oda army and the Tokugawa army were also panicking. ...,

"Wouldn't it? Kyushu Mamoru is going to bomb us together?"

"This ...... Maybe he'll do it!"

"Yes, Kyushu Shou is going to compete with Nobunaga Gong for the governor, this is a matter known to the world, if he takes advantage of this opportunity and he bombards us and the Takeda Army together, it is entirely possible to do it......"

"Abominable ......"

As a result, not only the Takeda army was shaken, but even the Oda army and the Tokugawa army fell into a considerable degree of panic together.

Masanobu Takasaka, one of the four ministers of the Takeda family, couldn't help but run to Shingen's side and said loudly, "Shingen Gong...... What should we do now?"

The horse farm letter also hurriedly ran over: "It's very unwise to continue to fight in this situation, right?"

Shan Shan Changjing said: "My subordinates feel that we should retreat temporarily...... Otherwise, you may get into a very troublesome situation. ”

On the other side, Sanada Yukimura, the "first soldier of Sanada Fuso", was still attacking the Oda army, and he shouted loudly: "I don't believe that Kyushu Shou dared to open fire, he shouldn't be so ruthless, right? This must be acting!"

But he immediately received an order from his father, Sanada Masayuki: "Yukimura, quickly withdraw for me! Don't you notice? Even the soldiers of the Oda family are afraid, which means that this is not an act, it is really possible to fight with their own people, otherwise the soldiers of the Oda family would not show such a frightened look...... They thought that Kyushu Shou was really likely to open fire, so they would be scared like this. ”

Sanada Yukimura looked around the battlefield, and sure enough, not only the soldiers of the Takeda family were afraid, but even the soldiers of the Oda family were frightened, and it really didn't look like acting.

"I'm still a little closer, but I'll be able to get Nobunaga's head!" said Sanada Yukimura furious.

"Withdraw, even if we don't take off Nobunaga's head this time, we will have a chance to ...... next time" Sanada Masayuki issued an order for the entire army to retreat. At the same time, Takeda Shingen, who was on the other side, also raised his hand and made a retreat move.

For the confident Takeda family, Oda and Tokugawa have nothing to fear, they just need to find another opportunity to fight a tough battle with Nobunaga again to win, there is no need to divide the victory under the threat of artillery.

Don't fight uncertain battles, this is the philosophy of the first warlord of the Warring States, Takeda Shingen. (Your support is my biggest motivation.) )
