"Killing A Bird With Two Stones"

"Oh, this, quack?" Yaya pointed at the choker and couldn't help but make a smug smile. "This choker will create a barrier to protect me, quack. It can even block lasers and bullets, quack!" 

The duck patted his chest and lifted his chin high, acting arrogant. Well, he had the right to be proud since his choker was actually amazing. 

Even Lai Jiayi thought so. 

"Wow, so I won't fear anyone harming you, right?" Lai Jiayi looked at Yaya with bright eyes. 

"Yes, quack! I can protect myself, quack!" Yaya nodded with a wide grin. 

"Then...can the choker always be active or do you need to recharge it after a few uses?" 

"I can use it four times, quack, and after four times producing a barrier, I'll have to recharge it, quack, " Yaya replied bluntly. 

Of course, he didn't tell Lai Jiayi that to recharge the choker– he needed to consume the girl's electricity bill. It's not even her house but her friend's house, right? So no problem!
