It seems that when humans swim, they all have to rely on their arms, while Mermaids only need to flick their tails, and then shoot through the water like an arrow!
The main thing is, although they don't have gills, they can still breathe freely on the seabed like ordinary fish!
This is something humans could never do no matter what.
So if humans want to improve their swimming skills, extending the time they can hold their breath in the water is extremely important.
But right now, Si Wuxie can already hold his breath for one or two minutes, which is already very impressive, yet his speed is still not enough!
What exactly should he do?
Is it because Mermaids have tails, or can humans also try to use their lower body like Mermaids do and exert strength there?
If he uses both his legs and arms together, would it be twice the result for half the effort?
After taking a shower, Si Wuxie was already getting ready for bed.
But Xiang Baobei suddenly jumped up.
