But at this moment, under the wide water, there was a sudden violent vibration.

Feeling this power, Chen Ping's heart moved slightly.

At this moment, all the mermaids turned pale with shock.

Although Chen Ping didn't know what happened, but when his eyes fell in the distance, he found that a huge water column suddenly rose not far away.

Immediately afterwards, the underwater began to become cloudy.

It seemed that something was about to emerge from the bottom of the water.

At this time, the mermaid princess also noticed something strange behind her.

Immediately she turned around, and the blue light ball in her hand flew towards the muddy place at this moment.

As the blue light ball exploded.

A burst of strong water fluctuations bloomed in this underwater world.

The mass of water elemental energy continuously condenses and rotates, forming a huge vortex.

And this vortex directly clears the turbidity.

Only then did Chen Ping realize that the thing that came out of the ground was actually a gigantic tortoise.

The tortoise shell is full of barbs.

The barbs are black and sharp, with these colorful colors on them.

Obviously, there are a lot of toxins in it.

And at this moment, Chen Ping saw the big turtle opened its mouth, and its tongue suddenly rolled towards the mermaid princess.

Between lightning and flint, Chen Ping's water elemental attributes formed a stream of water, which directly rolled back the mermaid princess.

This time, the mermaid princess threw herself directly into Chen Ping's arms.

"Princess, please don't mind, this is also to help you escape."

Chen Ping whispered something in the ear of the mermaid princess.

Then he let go of the mermaid princess, held the Canglong sword, and rushed towards the big turtle.

The two eyes of the big tortoise were like two bright lights, flashing red. At this time, it was already staring at Chen Ping tightly, as if it had already taken Chen Ping as its target.

Seeing Chen Ping approaching, it suddenly raised one of its paws, and stomped hard on the ground.

This time, a stream of water rushed towards Chen Ping.

Even if Chen Ping wanted to get out of the way, he couldn't do it at this moment.

Compared with the star-talented cultivators on the ground, he may be relatively strong, but underwater, compared with such a sea monster, there is no comparison at all.

In desperation, Chen Ping could only use the Canglong Sword to block himself in front of him.

"Buzz!"

With a buzzing sound, it swung underwater.

Chen Ping saw that on the Canglong Sword, there were actually some toxins flickering.

But then it melted into the water again.

At this time, Chen Ping suddenly remembered something, that is the Xuanwu turtle shell that was always by his side.

He has never used this thing, because on weekdays, this thing does not seem to have any other functions other than providing a strong defense.

Since the other party is also a turtle, why not try this basalt turtle shell.

Thinking of this, Chen Ping immediately took out the basalt tortoise shell from the ring.

And when the basalt tortoise shell appeared for a moment, the entire water surface became calm in an instant.

Chen Ping sacrificed the basalt tortoise shell, and a huge coercion spread towards the surroundings. Everything in the water respected the basalt.

Although what Chen Ping held was just this turtle shell, it was enough to make that strange big turtle submit.

The figure of the big tortoise suddenly crawled down.

Not only it, but also those behind Chen Ping and the mermaid princess also knelt down at this moment.

The big turtle's figure slowly faded away.

It walked without leaving a trace, but Chen Ping knew that it was just some coercion left in the basalt tortoise's shell that made the big tortoise afraid.

After a long time, Chen Ping found that the big tortoise had finally stopped moving, so Chen Ping put away the basalt tortoise shell.

But what he didn't expect was that all the mermaids in the mermaid country behind him didn't move at this time, and kept kneeling in the water.

Even the mermaid princess is no exception.

Finally, Chen Ping saw Dr. Octopus.

"What are you doing?"

Chen Ping looked at the mermaid with some doubts.

Even the mermaid Zaku, who had been rude to him before, was crawling respectfully in the water at this moment, not even caring about his broken bones.

"The princess of the Mermaid Kingdom, Shui Wanrou, on behalf of all the mermaids in the Mermaid Kingdom, implore the Son of Prophecy to save us."

ha?

When Chen Ping heard what he said, he was taken aback for a moment.

Son of Prophecy?

Seeing Chen Ping's puzzled expression, Doctor Octopus said to Chen Ping, "The princess took Yu Yan's son to our underwater ruins."

Hearing what he said, the princess of the Mermaid Kingdom seemed to suddenly remember something!

Immediately afterwards, she held Chen Ping's hand without any explanation.

Until Chen Ping was dragged away by the princess of the Mermaid Kingdom, he saw those mermaids kneeling on the ground, not even daring to lift their heads.

Chen Ping closely followed the princess of the mermaid country, and at this time the princess of the mermaid country finally found out that she was so anxious just now that she actually held Chen Ping's hand.

"Sorry, I didn't mean to."

The princess of the mermaid country said while swimming, and actually started to apologize to Chen Ping.

Chen Ping smiled slightly, and then said to him: "Did that big turtle come here often to make trouble for you?"

Hearing what Chen Ping said, the princess of the Mermaid Kingdom immediately showed bitterness on her face.

"If it weren't for the ruins of our Mermaid Kingdom, we wouldn't have attracted so many underwater beasts."

The two talked and swam, and soon arrived at the ruins that the princess of the mermaid country said.

But when Chen Ping saw the ruins, only two words came to mind: shock.

This is a very large building group, but it looks a bit dilapidated, but even if it is dilapidated, from these huge and distinctive building groups, Chen Ping can see that it must have been very prosperous before.

Not only that, but there are actually many symbols left by the cultivators.

Although these symbols are peculiar, Chen Ping recognized me at a glance. They must have been left by human cultivators.

Because there are elements of various attributes in it.

And there are many well-preserved magic circles, as long as they are driven with vitality, they can be opened again.

"Was this a building group that belonged to humans before?"

Chen Ping asked subconsciously.

The princess of the mermaid country sighed softly, and then said: "At that time, the king of the mermaid country was still my grandfather. Because my grandfather had a good relationship with humans, they left this relic as a gift to us."

"And as a gift in return, we also gave away our entire 10,000 mermaid hearts."

Mermaid heart?

Chen Ping was stunned for a moment. If these mermaids lost their hearts, would they be able to continue to live?
