Haiyao rubbed the transparent bubble with a touch of nostalgia, seemingly quite familiar with it. After playing with it for a while, she swam over and pressed the bubble against Su Yuan.
The bubble was like a face mask stuck to his face. When Su Yuan opened his eyes, his head was already inside the bubble.
"This is......"
Su Yuan opened his mouth and tried to say something. The seawater in the bubbles was expelled, and no seawater rushed in while he was speaking.
The slight vibration in his eardrums made him hear the sounds coming from the underwater world even more clearly.
"Isn't it amazing? The way to use these bubbles was passed down from someone else, and it was Sister Haimeng who told me."
"I heard from Sister Haimeng that there are also crystal caves like this there, and the people in the ocean there would take these bubbles to trade with people on land."
"As long as it stays in the water, this thing can exist indefinitely!"
Su Yuan nodded in surprise. This thing was indeed quite amazing. Even though he had withdrawn the Heart of the Deep Sea Guardian, he would not suffocate from lack of oxygen.
These tiny, transparent bubbles seem to filter oxygen from the seawater into their interiors; although not much, it's barely enough to sustain a person's breathing.
If it could be a little bigger...
Just as Su Yuan was about to take out the strangely shaped fish from the crystal cave for a closer look, a loud noise came from the sand.
"Ahhh! Run!"
Haiyao was still putting small air bubbles into Shishi when a larger figure swam towards the three of them from the sand. Its meter-long mouth opened, revealing sharp, triangular teeth.
Bubbles shot out of her mouth like bullets, and as soon as Haiyao's tail began to sway, everyone's vision was blocked by a dense array of bubbles.
Having no fighting ability, Beya hid behind Su Yuan in fear, her tentacles instinctively wrapping around his waist.
Su Yuan raised his head, threw away the small fish, and unleashed the awakened power in his hand, transforming it into immense pressure in the seawater.
The air pressure is clearly much greater in the sea than on land.
Almost as soon as he clenched his fist, the huge fish with its gaping mouth closed its jaws tightly.
Its tail tried to swim away, but its body was instantly smashed into a pulp on the sand, giving it no chance at all.
Although the ocean is not Su Yuan's biologically advantageous area, his current strength as a fifth-tier elemental warrior allows him to precisely control the pressure of seawater and the gravitational pressure he releases.
The two combined can easily crush the monster fish's body into a meat patty.
As the blood mist dissipated, the surrounding fish and shrimp scattered frantically. Only then did Haiyao realize that she was no longer the little mermaid who hid in the Hailing tribe and knew nothing.
"Phew, that startled me! These guys always like to hide under the sand and rocks and ambush people. I almost forgot about it because I haven't been back for so long!"
"Then try to recall the rest, don't forget everything, our little tour guide."
"No, I still remember so many things about the Dream Coral Sea! Let me think..."
Ignoring Hai Yao's deep thoughts, Su Yuan went to the side of the large fish. Just as his fingers touched the scales on the fish, he heard a crisp system notification sound.
