Tang San dragged the Lion Tiger Sword Saint by one foot, pulling its body away from the Grand Animal Fighting Arena. The Lion Tiger Sword Saint was now his trophy. Not killing the opponent within the Grand Animal Fighting Arena meant that, in a sense, the Lion Tiger Sword Saint had become his slave. This was the right of free participants in the Fighting Arena. However, it was generally not exercised because both parties in the beast fight had a belief that they would fight to the death, making it difficult to enslave them.
That's why Tang San had sent so many thoughts to the Lion Tiger Sword Saint through his Spiritual Power after severely injuring him. Otherwise, if he had brought it out and it committed suicide, wouldn't that have been a waste of time?
