A joke with the opposite meaning

A monk keeps a BMW. As long as you say "Thank God", the BMW will run at a flying speed. As long as you say "Hello God", BMW will stop immediately. Xiao Ming paid a high price for this. Xiaoming is riding a horse. He wanted to see if it worked, so he said, "Thank God". Xiao Ming forgets the formula of stopping when he is excited. Seeing the BMW on the edge of the cliff, Xiao Ming suddenly remembered and said, "Hello God!" " The BMW stopped suddenly, and Xiao Ming's hanging heart was pounding. Xiao Ming touched his chest and said softly, "Thank God."

"......"

BMW ran out at once.

What happened in the end? Think for yourself!
