As soon as Gu Ji spoke, the atmosphere instantly became somewhat tense.
After a brief exchange, he learned that the man was named Riddle, from the United States, working as an electronic hardware development engineer at a tech company.
Betty also turned her head to look at Riddle. She could see that he was just a "sub-health" kind of office worker.
Anyone with a basic understanding of running knows that to keep the body stable and conserve energy, one must use the support and reactive forces from moving steps and inertia, particularly mastering breathing and rhythm.
But Riddle's steps were chaotic, and he was gasping with his mouth open, which would lead to rapid moisture loss in the oral cavity and increase the risk of airway irritation, causing a side stitch.
Riddle suddenly stood upright, looking directly at Gu Ji, smiling faintly.
"Haha, am I supposed to just stay put and wait for death if I don't come out with you?"
"Mr. Riddle, what do you mean by that!"
