"Dr. Wang, quickly save my father!" a young man shouted. The voice was very loud and anxious.
With a loud sound, he hit the door and came in.
"How could this be!" Pan Jun hurriedly helped the old man down and laid him flat on the bed.
Wang Yao reached out to take his pulse. It was too late.
The old man's eyes were still open. His mouth was open and bloody. It looked like he had something to say, but he could not because his heart had stopped beating.
How did this happen? Wang Yao stared at the old man who had died. He looked at the young man who was crying. Moments before, he knew the old man would die and could not be saved, but it was too fast.
"Is he your father?" he asked as stared at the young man crying.
The young man sobbed without speaking. He soon wiped away his tears and looked up at Wang Yao. His eyes were full of hatred. "It was you! You killed my dad!"
"You are crazy," Pan Jun said. "What are you talking about?"
