"The submarine could only scan the sea monster, but it couldn't see it."
"Couldn't see it?" Song He was stunned. "Was that thing moving that fast?"
"Partly because it moved fast, and partly because of the complicated terrain." General Wang explained seriously. "Most of the seafloor is flat, but there are also underwater cliffs. You understand that, right?"
"Of course. Just as there are mountain ranges on land, there are mountain ranges on the seafloor too. In fact, many underwater mountain ranges are even larger than those on land." Song He nodded. "After all, both are shaped by geological activity."
"That's right. Some sea monsters like to move around underwater mountain ranges. They seem extremely sensitive to approaching submarines and will warily hide in caves or cliffs, escaping pursuit like a rabbit with three burrows." General Wang described the situation.
"Our submarines are no match for the native creatures of the deep sea when it comes to knowing the terrain. We're worried about bumping into something. At those depths, where the water pressure is enormous, even a single collision can sometimes be fatal. For now, we don't dare chase them into the mountains."
"There have also been a few cases where we encountered sea monsters in open waters, but the submarines failed to catch them. The sea monsters were actually even faster!"
"You understand, right?" General Wang said. "You're both intelligent people. You should be able to imagine the scene and understand what the real difficulty is."
"Then... what's the speed of the research submarines?" Xiang Xiaotong asked.
"Converted to land speed, they can reach sixty kilometers per hour on the seafloor," General Wang said.
The master and disciple exchanged a glance and simultaneously sucked in a breath of cold air.
Sixty kilometers per hour—even for a car traveling on
