Hearing her theory about buoyancy and swimming in the water, Bobby wondered in his head: 'Exactly, the air is also another fluid just like water, and the similar buoyancy and floating theory still applicable to it. Thanks, Archimedes, for his beautiful principle… I failed to maneuver in the air just because I'm too focused on just the flight. Instead, I should use the advantages of the natural forces and reaction forces to my advantage. Now I understand. It's exactly like soaring a boat in the river with a pair of oars.'
He closed his eyes, craned his head upward, and took a series of long breaths. He then put pressure on the ground and jumped up in the air and he focused on his wings and started flapping them at the same time. Finally, he was gradually lifted above in the air, higher and higher as he flapped his wings.
