Robbing

"Come on, bring out those spirit stones. I don't have much time," Ning said with a hurrying gesture. 

Prawn Greenhorn looked at him with an angry look on his face. He looked at his son once before turning towards Ning.

"Why are you doing this? Did our family do something to antagonize you?" the man asked.

"No, I just need money, and this is the fastest way," Ning said with a bright smile that gave the man no reason to suspect him at all.

The man frowned for a few seconds and brought out 40 spirit stones before throwing them over to Ning. "Give me back my son now," he demanded.

"Of course, of course," Ning said. "Here you go."

He sent the kid back to his father. The man caught his son and looked him all over to see if there was anything wrong with him. 

"Are you okay?" he asked.

"Yes, father," the young man said. "But he took everything from me."

The man's eyes darkened as he looked toward Ning. "Kill him," he ordered.
