They came to the artillery, took out the shells and poured the contents of the barrels into the shells.

Wu Song looked confused, the shell was filled with **, but the contents of their barrel seemed to be liquid.

After loading, the shells were loaded into artillery and fired at Moby Dick.

The walls of Moby Dick were too high for the pirates' artillery to hit the people on the walls of Moby Dick, so they could only hit the walls of Moby Dick.

I only heard the sound of 'boom' incessantly, and the cannonballs hit the city wall one after another, making a dull sound.

This sound is somewhat different from the previous shelling.

Wu Song pondered for a long time, and his heart became more and more uneasy. These pirates don't do such strange things for no reason, there must be something famous in them.

Thinking of this, Wu Song jumped to the city wall, drew the dragon eclipse sword in his hand, and jumped outside.

"Monk Wu Song!" Yang Zi let out an exclamation when he saw Wu Song leap off the city wall.

The walls of this Moby Dick City are more than thirty meters high, even if Wu Song is a strong cultivator, there is great danger if he jumps down.

Not to mention, now that the two armies are fighting, under the city walls are the Wang pirates, even if Wu Song does not fall to his death, he will fall into the encirclement of the Wang pirates, what does he want to do?

Wu Song jumped down from the city wall, and in mid-air, he waved the dragon sword and inserted it into the city wall.

The Dragon Eclipse Sword was inserted into the city wall, creating some resistance and slowing Wu Song's fall a little.

Wu Song used the dragon sword to insert several times on the city wall, and finally landed smoothly.

After such a long period of shelling, the ground under the city walls was filled with gunsmoke, and the ground was full of deep craters blown out by shells.

The shelling of the Wang pirates continued, and Wu Song saw a cannonball flying from a distance and crashing into the walls of Moby Dick City.

Wu Song turned to look at the city wall, and sent down a puddle of red liquid in the place where the cannonball hit just now, which was enough to be a meter in diameter.

Apart from being coated with these liquids, the walls were undamaged.

Wu Song was right, the shell was not filled with **. What did the royal pirates risk their soldiers being killed by artillery to smear these liquids on the city walls?

At this time, another cannonball whistled, and this time the cannonball was slightly less accurate, and it did not hit the city wall, but fell on the ground not far from Wu Song.

The ground was soft, and the shells did not explode.

Wu Song walked over and carefully picked up the cannonball.

The shell was about the size of a person's head, black throughout, and on one side of the shell, there was a lid. Wu Song was bold and unscrewed the lid.

The shells were hollow and filled with a red liquid, much like blood.

Wu Song's brows furrowed, and he was even more puzzled. He looked at the cannonballs, and then at the walls behind him. At this time, after a round of artillery bombardment by the royal pirates, most of the city walls have been smeared with red liquid.

From a distance, the walls looked like they were covered with a red cloth.

Wu Song was puzzled, when suddenly a rain of arrows fell from the sky and shot at him.

It turned out that the pirates of the Wang family found that there were people under Moby Dick City, so they transferred archers to shoot Wu Song.

Wu Song swung the Dragon Erosion Sword, sending out several sword qi and cutting off the flying arrows. Then, the body was in a vertical position, and it was already several meters in the air.

He swung his sword, and with a little bit of strength on the wall, he flew higher.

With just a few ups and downs, Wu Song returned to the city wall.

"Brother Wu Song, what are you doing, why do you want to go down now that the city is so dangerous?" Yangzi said, Wu Song's actions just now made her face turn white with fright.

"I've made a discovery," Wu Song said excitedly, "where is the Lord of Beizhu Island? ”

Bei Zhu was directing the enemy somewhere in the city wall, and Wu Song and Yoko found her, and Wu Song handed over the cannonball.

"What is this?" Bei Zhu said, taking the cannonball, puzzled.

"Look," Wu Song unscrewed the lid of the cannonball, "there was blood in it for some unknown reason, and those pirates now contained this kind of blood in their cannonballs, and most of the walls were already smeared."

There is no way pirates could do such a strange thing for no reason, they have a plan.

I don't know what it is, you know?"

Wu Song considered that he was not a local and did not know much about the products here. Yoko and Beizhu were both born and raised here, or maybe they know each other.

"Judging by the taste, it should be some kind of fish blood, and it is most likely deep-sea fish. Bei Zhu dipped her fingers in a little blood, sniffed at the tip of her nose, and then she stuck out the tip of her tongue and licked it, "There was a little sourness in the taste." ”

"Isn't it poisonous?" Wu Song said. He guessed that there might be poison in the blood, and that the pirates were trying to poison the soldiers defending the city.

"It's not poisonous. Bei Zhu affirmed that she was a fifth-order demon general, and many races in the demon race were born with very developed senses, and could perceive things that the human race could not perceive. And Beizhu belongs to one of these races.

"Then that's weird, what is the purpose of the pirates' move?" Wu Song pondered.

"Wait a minute, this blood, it looks like the blood of a one-eyed fish. Next to Yoko said.

"What is that?" Wu Song asked.

"The monoculus is a deep-sea fish found in the nearby seas and is one of the foods of the locals. Its meat can be eaten, and because of the sour taste in the blood, many people use it as vinegar.

It's just that this fish can't be eaten too much, because not only its blood, but also its flesh contains a sour taste, and if you eat too much, your teeth will not be able to stand it. When some Terrans first came to the Middle Boundary Island, they didn't know the secrets of the Monock.

I thought this fish was delicious, so I ate it. As a result, their teeth melted quickly. ”

Yoko Road.

"But what does this have to do with the battlefield?" Wu Song faintly felt that there was a connection, but he couldn't figure it out for a while.

"Is that so?" Bei Zhu suddenly exclaimed.

"What's wrong, Lord?" asked Yoko.

Bei Zhu lowered his head and pondered, his brows furrowed tighter and tighter, and said slowly, "The reason why Moby Dick City is called Moby Dick City is because at the city gate, there is a huge whale skeleton, and everyone knows this allusion.

However, what many people don't know is that the real origin of the name Moby Dick is because the walls of Moby Dick City were built by grinding whale bones into powder and mixing them with lime and other materials.

Whales are one of the overlords of the sea, huge in size, an adult whale is larger than a large warship, and can devour thousands of fish in one bite. Neither the human race nor the demon race can compete with the whale at sea.

Its bones are tough enough to support its massive body. Because of this, the walls of Moby Dick City, built with whale bones as materials, are exceptionally strong and not afraid of artillery bombardment.

Before, by accident, I learned the secret. I didn't care about it at the time, but now it seems clear that the pirates' intentions were clear.

Although the bones of whales are tough, everything in the world has a nemesis, and nothing is perfect. I think the weakness of the whale's bones is the blood of the one-eyed fish.

Its blood can corrode whales' bones, and the Lord of Coral City, one of the people in charge of building the walls in the first place, must have known the secret and told the pirates. ”

As soon as Bei Zhu's words were finished, as if to confirm her words, a soldier next to her shouted in horror, "Island master, it's not good, come and see!"

Wu Song, Bei Zhu, and Yoko hurried to the soldier's side and looked down in the direction he was pointing.

The walls of the city that were a few meters away from them began to melt like ice under the scorching sun. Just as a few people were watching, a stone peeled off and fell under the city wall.

This is happening not only in the place they are looking at, but everywhere else, where the blood of the eye fish is covered.

If you listen carefully, then in the rumbling cannonball, a sizzling sound can be heard. It was the sound of bubbles bursting after the blood of the one-eyed fish corroded the walls.

And so it was. Bei Zhu let out a long sigh, a kind of despair on her face.

The walls of Moby Dick City are their last resort, and if they are corrupted, they will have to engage in melee combat with the royal pirates.

There were less than 2,000 soldiers in the city, and the royal pirates numbered almost 10,000, which was too much difference.

Moreover, after the city is broken, the people in the city will inevitably be poisoned by the fire, which Bei Zhu does not want to see.

Judging by the current rate of corrosion, after a few hours, the walls will be corroded to half their thickness. When the time comes, the cannons of the royal pirates will be able to penetrate the city walls.

"Island Master, what should I do?" said Yoko anxiously.

Bei Zhu's brows tightened, but he couldn't come up with any good way for a while.

"I have a way to stop the walls from corroding, but I can slow down the corrosion and buy some time. Wu Song said.

Moby Dick City is in a great crisis here, and there is an atmosphere of triumph in the pirates of the royal family.

"City Lord, you are still powerful. The walls of Moby Dick City, which can't be broken by hundreds of cannonballs, you can solve it with a few buckets of fish blood, high, really high. ”

Captain Redbeard said loudly beside the Coral City Lord.

"Hmph! Bei Zhu's girl doesn't know the goods, so I'll let her see how good I am. The Coral City Lord said hatefully.

There's a reason why the City Lord of Coral City rebelled.

He is one of the elders of the Middle Boundary Island, and he came here when the Middle Boundary Island was a desert island where birds don't, and he is the first generation of residents here.

A few years after his group came to the Middle Boundary Island, Bei Zhu's group arrived here.

The group of people of the city lord of Coral City are all Terrans, and the group of Beizhu people are all demons.

At that time, more than twenty years ago, the human race and the demon race were in the most intense stage of the war, and the two races regarded each other as mortal enemies.

It is conceivable that in order to fight for control of the Middle Boundary Island, the two sides fought to the death.

In the end, the two sides were evenly matched. But in the fighting, both sides suffered heavy casualties. If the fight continues, then both sides will end up together.

So, as a last resort, the two sides drew a line and divided the Middle Boundary Island into two, each living in its own territory.

Later, after years of running-in, a truce was declared between the eastern and western continents, and trade between the human race and the demon race resumed.
