50, if you have hands, you'll be fine.

Almost an hour later, the bus arrived at its destination smoothly, and the two got off and headed to the beach.

They arrived at the changing room and changed into the swimsuits they brought along.

Lin Zichen wore only a pair of swim trunks, revealing his well-sculpted, muscular upper body.

Shen Qinghan, as always, was dressed modestly, only exposing a bit of her thighs, embarrassed to reveal too much in a public setting.

"Fewer people over there, let's go that way," Lin Zichen said.

"Okay," Shen Qinghan replied, nodding her head and obediently following Lin Zichen.

Soon, both of them entered the shallow water.

Lin Zichen first had Shen Qinghan test how long she could hold her breath underwater, to see if she could still last over 10 minutes like the last time.

To his surprise, Shen Qinghan's performance shocked him, holding her breath underwater for 20 minutes.

"Zi Chen, how much?"

"20 minutes and 38 seconds," he answered.
