Lu Ao casually asked, "Then why don't you come along?"
"Isn't there a coral reef down there? Coral is so fragile—how could we risk disturbing it? We should dive farther away, in another part of the sea."
Hearing this, Huang Ningna gave a wry smile from the side. "This really used to be a paradise for coral, but it stopped being one two years ago. The coral below has basically all died. You'll see once you go down."
"No way. Isn't this place practically untouched by people? How did it all die?"
"Because of rising seawater temperatures. If we don't transplant coral here today, this area will basically have no coral left."
Lu Ao felt awful upon hearing that.
He did not say much, only asked, "Are the tools ready? I'll go down and take a look."
"They're all ready—the metal frames, underwater glue, small coral... Go down first and see how they should be planted."
"Mm."
They had already discussed a plan before coming. They would install metal frames on the seabed, transplanting some of the young coral into the horizontal grids of the frames, while using a vertical planting method for the rest, tying it to upright metal frames.
Of course, exactly how and where to do it would have to wait until they had gone underwater and surveyed the specific conditions.
Lu Ao had the best diving skills. After putting on his diving suit, strapping on an air tank, and taking his camera, he led the way into the water.
This was shallow sea within the photic zone, and the water was highly transparent. Even at a depth of fifty or sixty meters, the seafloor was still clearly visible.
However, looking down from the surface, the seafloor's condition was still hard to make out. The entire stretch
