Purpose

The tiger's anger scared Alex. He had seen him angry before, but not this angry. This was killing Intent in his anger that didn't come naturally. 

Alex had to step aside in fear of what would happen to him.

Bai Jingshen's fury rose to new heights. His daughter was dead. His son-in-law was dead. His granddaughter was dead. This was an attack on his family and he couldn't stand it.

He burned with anger, the air around his rippling with his Qi that rose from him. He couldn't calm himself. He needed blood. The blood of his enemies was the only thing that could calm him.

That was what his primal instincts demanded.

And with his anger formed something in his forehead. Something that glimmered in golden light, something that flickered so fast that the distracted couldn't notice in time.

Bai Jingshen hadn't realized that he had nearly revealed a very deep secret that he had hidden about himself for the longest time.
