She was certainly gone by now.
Soon David came to inform them:
"Get your gear ready, we'll be at our destination in seven or eight minutes."
After these words, Lu Xiao stood up and came over to help Wen Xian get ready with her diving mask, snorkel, and fins.
Since they would be underwater for an extended period, Lu Xiao seriously checked her air tank for any problems—underwater, the tank was their lifeline.
Wen Xian also helped him, and by the time they were nearly finished packing, everyone else was ready to head into the sea.
David was the first to prepare to go down. With his back to the sea, he sat on the edge of the boat, pulled down his diving mask to put it on, and then flipped backward into the water.
Splash followed by splash, and soon, the disappeared David poked his head out from the water once more, waved to them, signaling everything was fine.
Next, Ailin went down.
Wen Xian knew how to swim, but deep diving was a rarity; she still made thorough preparations.
