Everyone on the deck cautiously looked at the sea around them, and Xu Fu instructed the disciple to drag the body of the disciple on the ground into it first. Then he threw the headless body of the blue-scaled merman into the sea.

Just when everyone thought it was okay, there was a non-stop crashing sound from the bottom of the boat, and Xu Fu took a look at the sea with a torch, and immediately gasped.

At this time, the mirage was already surrounded by the black shadows of the mermen, but those mermaids were only slowly hitting the hull of the ship, and did not climb onto the boat to attack.

Xu Fu guessed: "The reason why they didn't climb the boat is that they must be waiting for an order to attack." The surrounding disciples were frightened when they saw the dense mermaids under the boat.

Xu Fu suddenly remembered that it was recorded in ancient books: "Sharks generally live in groups, and there will be a shark king in a group of sharks." All the sharks will obey the command of the shark king. So Xu Fu said to the disciples: "Everyone get ready, those sharks haven't attacked yet because their shark king has not yet arrived, they are waiting for the shark king's attack order, everyone get ready." Bring the oil to this deck as well. ”

One of the disciples asked curiously, "Master, this mermaid lives in the sea like a fish, what is it doing with fire oil?" Xu Fu wiped the cold sweat on his forehead and said, "You don't know, right? Although this merman is bloodthirsty and murderous, he is extremely ferocious. But the oil contained in its body is flammable, as long as it is stained with a little spark, it will ignite, even if it is water, it will not be extinguished, and it is also resistant to burning, a drop of merman fat can burn for several days. ”

Another disciple suddenly looked at Xu Fu and said, "I understand, Master wants to use fire oil to burn the merman, right?" Xu Fu nodded and said, "You also saw it just now, the scales of the merman are very hard, and ordinary knives and arrows can't hurt it at all, so you can only attack with fire." As soon as those disciples heard that Xu Fu knew the merman very well, they immediately went to the cabin to carry the oil in the cabin.

The night was getting deeper and deeper, and the sky that had been bright and starry was obscured by dark clouds. The merman in the sea was still hitting the bottom of the ship, and everyone on the deck was staring at the sea with wide eyes, for fear that the merman would suddenly climb onto the boat and attack.

At this moment, a beautiful singing voice came from the sea in the distance, as if many young women were singing, and at this time the sea was also thick foggy.

The disciple who heard the chanting could not contain his curiosity and turned to look into the sea, but the sea was still empty.

The mermaids, who had been hitting the deck non-stop, stopped hitting the bottom of the ship when they heard the sound.

A disciple smiled and asked, "Master, in the middle of the night, there are still women singing in the sea, and this singing is very good!" Xu Fu suddenly realized: "Oops, this is the voice of the shark king, do you think this is the singing voice of a young woman?" Big mistake, I tell you, this is the sound of the devil in hell, hurry up and get ready, the mermaid king has arrived, and they will attack at any time. When the disciples heard this, they all showed their weapons and stared at the silent sea.

At this time, the thick fog had drifted all over the sky, the original thud of hitting the bottom of the ship had also disappeared, and the empty sea was as silent as death. The people on the boat only heard the sound of their companions breathing and heartbeat.

"Whew. Woo. Suddenly there was a hoarse and low roar from the silent sea, and the calm sea suddenly boiled like boiling hot water, and the mermaids swam to the surface from the bottom of the sea, stretched out their claws to grasp the hull of the mirage, and roared and climbed to the boat.

Everyone on the boat picked up the giant crossbow on the side of the ship and fired, but the scales of the mermaids were too thick, and the number of mermaids was too many.

After a while, there were already mermaids who climbed onto the deck, stretched out their claws and grabbed the people on the deck. Suddenly, the screams and cries on the deck spread in all directions.

Because of the influence of the smell of blood, those mermaids became more and more crazy, and their ugly eyes emitted a dark red light, which was particularly terrifying under the light of the fire.

After Xu Fu tried his best to cut down a few sharks who were entangled in him, he shouted to his disciples: "Find a way to kill that shark king first, as long as the shark king is dead, the other sharks will not have to be afraid." Because these sharks are all at the behest of the shark king. ”

A disciple turned his head and shouted: "But there are too many sharks, and the shark king has not appeared, how can I find it... Yes...! Before he could finish speaking, the disciple was pierced through his body by the shark's claws. Then several mermen swarmed up and tore the disciple into several pieces, and the internal organs in his stomach flowed to the ground.

Xu Fu was furious when he saw this tragic situation, and with a single sword, he pierced the two mermaids who rushed towards him, and the dark green fishy blood splashed Xu Fu's body. Xu Fu wiped the blood on his face and came to a lathe crossbow, there was a huge arrow on the crossbow, after Xu Fu threw the torch to the sea, he saw a big black shadow in the sea water surrounded by many small black shadows, Xu Fu understood that the black shadow in the middle must be the shark king, so he raised the giant crossbow on the boat and shot at the black shadow in the sea water.

I saw that the giant arrow pierced directly through the black shadow, and the dark green blood suddenly stained the sea water green. The dark shadow let out a low roar of pain and turned to swim into the depths. The mermaid on the boat heard the roar and ordered to stop the attack and jumped back into the water. The "poof" and "poof" sound made by the merman jumping into the sea attracted Xu Fu's attention.

Xu Fu took the torch and instructed his disciples to throw the wooden barrel filled with fire oil into the sea, and when the mermaids saw the wooden barrels thrown on the boat, they grabbed it with their claws and swam into the deep sea.

Xu Fu threw the torch into the sea, and the flames suddenly burst into the sky. Those mermaids who were stained with fire oil were suddenly engulfed in the fire, emitting a smell of burnt and fishy.

The mermaids on fire swam into the flock of mermaids, and the oil in the mermaid's body is already flammable, even in the seawater. Suddenly, the dark sea was reddened by the firelight.

There was a disgusting fishy smell in the air, and Xu Fu looked at the merman corpse in the sea and frowned. He then instructed the disciples who were not injured to carry the disciples who had been injured in the battle into the cabin of the ship for treatment, and then threw the corpses of the mermen on the ship into the sea.

The entire deck was stained with dark green merman blood, and there were also a lot of bright red human bloodstains. Although he killed a lot of mermaids and seriously injured the merman king this time, Xu Fu's disciples also suffered a lot of casualties. The deaths of those dead disciples were very tragic, and all of them were bitten to pieces by the merman.

Xu Fu sat on the ground, looked at the sea in the distance and sighed: "Alas! I didn't expect this shark to be so powerful, what about the monsters on the three demon mountains of Abbot, Penglai, and Yingzhou? Just to deal with a group of mermen, his disciples have suffered so many deaths and injuries, what if they go up to those three demon mountains? ”

Just when Xu Fu was thinking nonsense, a disciple handed him a piece of cloth: "Master, are you okay?" Are you hurt? Xu Fu took the cloth and wiped the blood and sweat on his face, shook his head and said, "It's not hurt, it's just that I'm old, and my body is a little unbearable." What happened to their injuries? ”

The disciple also sat next to Xu Fu and said, "Their injuries are not too serious, they have all been bandaged just now, and they will be fine after a few days of rest." Xu Fu nodded reassuringly, patted the disciple's shoulder and asked, "How is it?" Are you afraid? Do you dare to accompany your teacher to the demon mountain? The disciple laughed, "Aren't they just a few mermaids?" I'm not afraid! Master, you said that people from the Mountain Sect should not be afraid of whatever they encounter. So! This time, I must accompany the master to break through those demon mountains. Xu Fu smiled and nodded: "Hmm! Not bad! Good boy, you are worthy of being a person from my mountain school, and you are not wrong as a teacher."

The disciple smiled again and said, "Master, don't say it's a few demon mountains, it's the Netherworld, I'm going to break into it too." Besides, and Master, you are here, what am I afraid of! Hahahaha"

Xu Fu also laughed, and this hearty laughter spread far away on the silent sea, echoing in the quiet night for a long time. It's as if nothing had happened.
