Su Jiu tiptoed outside the window and dabbed her finger slightly on her tongue before gently pressing it on the window paper. She tilted her head and peeked inside.
Chen Yuchan had walked into the inner room, taken out dishes filled with pastry, and laid them on the little table. Then she took out a porcelain jar.
Chen Yuchan opened the lid. It looked like some kind of soup, hot steam whirling up. She turned and glanced at the tightly shut door. Reassured, she fished out a paper packet. It was a fine powder that Chen Yuchan ended up dumping into the porcelain jar until nothing was left in the paper packet.
Chen Yuchan then stirred it well and put the lid back on.
Outside the window, Su Jiu's bright eyes darted back and forth as she pulled the corner of her mouth into a foxy smile.
