Heavy goals

Xie Jie did not say anything and simply stared at Mo Qiang until the latter started to feel uncomfortable all over. A normal day. She wanted to have a normal day for once in her life, was it too much to ask?

" Oh, are you prepared to set off?" Feng Jue's voice came from behind and Mo Qiang turned to look at the hybrid mer. But soon furrowed her brows when she saw that the mer was holding two vases, three shiny jackets and two boots with shiny buckles on them. He was also wearing her pants that had shimmer on them. 

" Why are you robbing my house? More importantly, why are you wearing my pants that too one one-on-one?" Mo Qiang asked upon seeing the heavy backpack that Feng Jue was carrying behind him. When he came into her house, the pack was thinner than a juice box that had been sucked dry but now it was big and fat. It was also jingling. 

Why was it jingling?
