Academician Ding had been under immense stress for the past couple of days, which naturally took a toll on an elderly person's health. He fell ill on the day of his return to his homeland, but the responsible old man still insisted on detailing the specific situation before he could rest easy to recuperate.
Academician Ding was also somewhat paranoid, the memory of the Brain Worm's appearance still fresh in his mind. Bai Zhongqi was worried about the extent of the Brain Worm's development on Earth, how much control it had over human society. Considering this, Academician Ding was deeply concerned. Clutching the detector that Bai Zhongqi had given him, he would scan anyone he met—by now, he must have scanned dozens of people since his return, but no abnormalities were found, which somewhat eased his mind.
