Several wide, dark green kelp fronds were wrapped around the large, thick propeller, immobilizing it.
The two divers exchanged a glance, both incredulous.
They had never seen kelp entangle a propeller before. Kelp is such a fragile plant, and the propulsive force of a giant ship's propeller is immense; the kelp would be torn and shredded upon contact.
Moreover, the Malacca Strait was not a habitat for kelp, and these particular plants looked unusual.
"Let's cut the kelp."
One diver signaled this intention, and then they proceeded, one with a knife and the other with scissors and pliers, to cut the kelp.
Snap!
The knife felt like it was cutting through steel; the kelp was incredibly tough.
No matter how hard the diver tried, he couldn't sever the kelp; he only managed to make a few centimeters cut, tiring himself out.
"Damn, what the hell is this?"
The other diver's scissors broke, and he looked incredulous.
