Gu Junyan rarely spoke so violently, and for a moment, everyone seemed to be frightened.

"Humph! You don't end well with that snake-like woman! The merfolk said hatefully, "My people! Now a large number of people have fallen ill and died! ”

Snake Girl? Brigitte?! She's been to Netherworld?!

Gu Junyan was stunned.

"I'm not in the same league as that woman...... I'd be willing to heal your people if I could, but ...... You also have to tell us what happened, Penglai Island...... Why did it become the way it is!? Gu Junyan looked at the mermaid, and there was an inexplicable trust in his voice.

The mermaid was stunned: "What you said is true?!" ”

Gu Junyan nodded, "We never deceive people, if we deceive you, when the time comes, you can kill us, this is your territory." ”

The mermaid was stunned for a moment, and then said, "No, unless you save people first!" ”

Gu Junyan nodded, "No problem!" ”

After that, the fire attribute melted the ice into an ice cave, freeing a mermaid.

The mermaid commander looked at it and whispered, "You, go find someone and bring the prince out!" ”

The merfolk looked at everyone in disbelief, turned and dived into the water.

But in the middle of the night, a person in the cage was pushed out.

However, I suddenly saw this fish...... No, when this mermaid was born, Gu Junyan was still shocked.

The half-human, half-fish mermaid in front of him had two fangs that were two inches long, his eyes were red, and he glared at Gu Junyan.

"Xiao Xun! Help me hold him down! Gu Junyan turned his head and said.

Xiao Yixun agreed, opened the cage like lightning, and a sharp hand knife slashed at the back of the male mermaid's neck.

"You ......" The mermaid commander looked at Gu Junyan's actions, a little sluggish.

Gu Jun took his pulse without raising his head, and said in a low voice, "What's your name?" ”

The blonde mermaid whispered, "My name is Wu Na, and this is my husband...... York. ”

"What status?"

Wu Na bit her lip before she said, "I am the leader of the mermaid tribe in this sea area...... Yorkta......"

Gu Junyan was silent for a moment, "This situation ...... How long has it been going on? ”

Wu Na was stunned, "Two hundred years ago...... It's all those guys from the demon clan! Brought the virus to the sea! Countless clansmen were dragged by them to do experiments!! ”

Two hundred years ago, after the destruction of the Demon Realm's Ten Thousand Poison Gate.

Gu Junyan was silent for a moment before he said, "That woman, is her name Brigitte?" ”

Wu Na nodded, "How do you know?" ”

Gu Junyan was silent for a moment, did not answer the other party, but said lightly: "I can save it!" ”

Wu Na was stunned for a moment and muttered: "How many deep sea witch doctors have said that they can't save you......"

Gu Junyan smiled and fed York a blood poison antidote to his mouth.

After a short time, York's patterned skin continued to shed down, his fangs became shorter, and his whole person returned to his normal appearance.

Gu Junyan pricked a needle in the sandalwood, and York woke up faintly.

"It's ...... Wu Na?! What's going on?! York's eyes had reverted to turquoise, and he looked around in shock.

Gu Junyan didn't have time to listen to her explanation, just looked at Wu Na, "Now, can you trust us?" ”

Wu Na nodded, and Chu Yuanyuan and Mu Huaiqian sacrificed the fire attribute at the same time, dissolving this large iceberg.

Wu Na, who had regained her freedom, hugged her husband excitedly, "York! My dear York! I really thought you were going to die! ”

York was also holding Wu Na, and he vaguely remembered what had happened during this time.

Gu Junyan looked at this pair of hard-working people and shook his head.

"Now...... Can we have a good talk? Gu Junyan spread his hands, looked at the group of people behind him, and said in a low voice.

Wu Na regained the prestige of the patriarch, looked at this group of humans, and said in a low voice: "It's not safe here, let's go to a safe place and say!" ”

Gu Junyan was stunned.

Then he went to the sea with Wu Na.

Basically, as long as you are a person from the Upper Four Realms, your breath-holding skills are good, and it is not a problem to stay in the sea for a day or two.

Therefore, everyone jumped directly into the sea and followed Wu Na to an underwater paradise.

Gu Junyan, who saw the ocean for the first time, was still shocked.

The beauty of the sea is beyond almost everyone's imagination, with gorgeous corals, soft sand on the bottom of the sea, and fish swimming in the passing...... It's like another wonderland on earth.

Wu Na looked at this group of unusual people, and said lightly: "You saved my husband, and you are kind to my mermaid clan, I will tell you what I know!" ”

Gu Junyan smiled, "Listen up!" ”

"It happened about two hundred years ago...... "Wu Na smiled wryly.

Two hundred years ago, the Netherworld Island at that time, still called Penglai Island, was a fairyland-like existence on earth.

Countless strangers yearn for the treasure hunt, the sea is a place where crisis and recovery coexist, and Penglai Island is also extremely famous in the world, not only because it is a fairyland on earth, but also because the residents of the island are extremely simple, there is a magical water source on this island, and the couples who drank this water gave birth to children, most of whom were twins.

Therefore, the people on the island often use the seafood from the sea to go to the main road to exchange for grain and rice.

Countless houses were built because of this, and even when Gu Junyan and the others came, they saw some dilapidated houses, but the people inside, without exception, all died.

At that time, the people of the island and the people of the sea were still very close, after all, terrestrial and aquatic animals have always been in a state of non-interference.

"But...... It didn't take long for them to go crazy! A strange disease is circulating among them! People with this disease will only suck the blood of their loved ones at first, and their eyes will turn red and grow fangs, but in the end, as long as it is human blood, they will suck it, and it will be difficult to survive without sucking blood! They're all crazy! By the end, the island was full of dead people who had been drained of blood! ”

"They had no choice but to turn their gaze to the sea, and our mermaid tribe couldn't bear it anymore and launched a counterattack, until one of them was bitten by them, although he bled out, but luckily picked up a life, and everything became different...... This strange disease in the ocean is not limited by the blood of the closest relatives...... Countless clansmen have contracted diseases and killed each other because of this...... "Wu Na seemed to think of something, and couldn't help but cover her face.

"But the smell of blood in the ocean can cause extreme excitement among deep-sea sharks! Under the ravages of sharks, we suffered a lot of damage...... Even my husband ......"

The crowd fell silent.

Gu Junyan said curiously: "That...... Are the sharks alright? ”

Wu Na shook her head, "There is nothing wrong with sharks, this poison seems to be only for humans, and mermaids, as half-human and half-fish species, are almost ...... It's going extinct. ”

"And the people on this island, you didn't kill them?"

"Part of it...... Because some of my husbands, my people, were sick and were forcibly imprisoned by us, but they needed to suck blood, so as long as people came from the island...... We'll ......," Wu Na whispered.

Gu Junyan was silent for a moment.

"Old man Yao, what do you think of Huaiqian?" Gu Junyan said curiously.

Yao Jun said cautiously: "It's no different from blood poison, but blood poison seems to only spread in humans, and the mermaid tribe is difficult to be poisoned because it has half human blood." ”

Gu Junyan nodded, "The most important antidote to blood poison is fish bone glue. ”

"But...... Yin Tian Immortal Jun's corpse is a little different from blood poison? Mu Huaiqian pondered.

Xiao Xun raised his eyes and looked at Wu Na, "Some time ago, could anyone else come to this island?" ”

Wu Na nodded, "It's a snake girl, she said her name is Brigitte." ”

"What did she do?"

Wu Na frowned, "I didn't do anything, I just threw a few corpses on the island......"

"The corpses...... Have you eaten? Gu Junyan said tentatively.

Wu Na shook her head, "Those corpses are not fresh, not to mention, when they are sent, they only have skeletons!" ”

Gu Junyan: "......"

Okay, some things have gradually surfaced, Gu Junyan sighed and looked at Wu Na, "I will help you heal your people, but you also have to promise me one thing." It's all bones, otherwise, there may be new virus mutations......"

Wu Na nodded, the current mermaid tribe is extremely depleted, as long as she can stop this terrible virus, she, as the leader, is willing to do anything.

Wu Na is still a qualified leader, and the source of the virus was blocked as soon as the problem was discovered, and those people were basically locked in a cage.

Yaojun and Mu Huaiqian each distributed the antidote, and the Xuexue Blood Poison Pill was a strengthened version, the medicinal power was stronger than the original, and the healing effect was not bad.

Gu Junyan sat on the beach and looked at everyone.

"Why did Brigitte come to Netherworld at this time?" Hua Xiangrong was a little puzzled.

Xiao Xun's eyes were dark, and he said lightly: "Because...... Now that the two worlds of immortals and demons have been opened, many immortals have gone to live in the demon world, and these corpses and bones ...... Being found in the midst of it will inevitably cause an uproar, the Netherworld Island has been abandoned for a long time, and there are human skeletons everywhere, even if there are a few more corpses, no one will find them. ”

Gu Junyan sighed, "In other words...... The Emperor of Heaven began to research new medicines...... Yin Tian Immortal Jun's bones were obviously a high-level failure. ”

"The most important thing now is that the news of the merfolk must be blocked, if ...... If they know that blood poison can spread at will among the merfolk clan, then the production of new blood poison will not be far from success! Mu Huaiqian clenched his fists.

"Now, I've started to test the medicine with the Celestials...... However, immortals with low ability are obviously unable to observe samples better, but their ability is relatively high...... It's extremely easy to attract attention......" Luo Shen said hatefully, "Qin Xuan, this old thing! What a ruthless heart! ”

Gu Junyan stopped talking, she still felt that something was wrong, but she couldn't say it......

Why...... The Emperor of Heaven took the Guiyuan knife and wanted to send his acquaintances? Gu Junyan had a flash of inspiration in his mind, but he couldn't catch it after all.
