"Yes, underwater," Fei Ye explained, "this planet we're on, approximately seventy percent of it is covered in water. This has resulted in a vast world beneath the ocean's surface, one that even countless abnormalities can't completely interfere with. Moving along the seafloor, we can avoid the attacks of these abnormalities to the greatest extent."
"I see..." Xiao Yi mused thoughtfully, "So the vehicle under construction is a submarine..."
"That's right," Fei Ye said, "Xiao Yi, now that you understand, you'll just have to wait a little longer. We still need some time to repair the submarine..."
"I see... I'll leave it to you then."
...
After that, Fei Ye devoted himself entirely to busying himself with the submarine.
It was necessary to do this to end this absurd crisis... Through this noble cause, Fei Ye mobilized all available resources and manpower, striving to resolve the issue as quickly as possible.
