Min Yu said nothing, but Old Madam Yang's voice could be heard over the phone.
"Yao, have you been busy recently?"
Huo Yao would call Old Madam Yang every week at the same time without fail. Old Madam Yang did not receive any call from Huo Yao in the past couple of days, so she got worried and called.
"Granny, this is Yu." Min Yu went quiet briefly before he spoke.
Old Madam Yang was caught by surprise when she heard Min Yu's voice. She did not expect him to answer the phone. She quickly snapped out of her surprise and said, "Huh? Hi, Yu. Where is Yao?"
Min Yu raised his head and glanced at the young woman lying on the hospital bed. He tightened his fists slightly, but he sounded completely normal as he said, "She's busy conducting experiments at school. Do you need her for anything? Since there is no signal in the laboratory, she probably did not bring her phone in."
