When Zhao Xiaodie brought Ye Wudao to Dr. David's office, there was already no one there, and no sign of Dr. David.
It seemed that Dr. David, sensing danger, had already fled, but he had left his notebook behind, probably because he was too hurried to pack up everything.
Zhao Xiaodie took Dr. David's notebook and then left the place with Ye Wudao. Strangely, aside from the security guards and Dr. David's subordinates who were injured by Ye Wudao and could not move, no one else came out to stop them.
As for Zhao Xiaodie's senior, Liu Shaojun, who had been on the rooftop earlier, he had been struck by a palm from Ye Wudao who had rushed over. Although he didn't die, he probably wouldn't be able to get out of the hospital bed for ten to twelve days.
Fortunately, Ye Wudao had managed to save Zhao Xiaodie in time. Otherwise, none of the people in this building would have escaped; they all would have ended up buried with Zhao Xiaodie.
