Chen Kai had heightened his vigilance upon entering the construction site, yet he hadn't anticipated that such an event would occur—in fact, no one could have foreseen when danger would befall them.
The ground collapsed, and seeing a worker about to be struck, Chen Kai rushed over without regard for his own safety, pushing the worker out of the way, but was unable to dodge himself and was hit hard by a falling rock.
Everyone was stunned, momentarily unsure of what to do, and after what seemed like an eternity, a worker finally cried out in panic,
"The Chairman has been hit by a rock, hurry and take him to the hospital, call an ambulance!"
That statement snapped everyone back to reality, and people, frantic, took out their phones to dial emergency services, then waited anxiously on the spot.
