Every time, the small battlefield would be available for one year and a half, after which everyone would be teleported out with no exception. But usually, after half a year, the teleportation portal would be activated and fights at the small battlefield would come to an end.
Half a year was enough to tell which side was the winner. Either the four races overwhelmed the humans or the other way around. Once the result was clear, it was pointless to go on. The losing side would began to retreat.
This time, there were quite a number of powerful warriors on the human side. As far as numbers of warriors were concerned, human side was not weaker than the four alien races. What was more, Lu Li defeated the allied forces of the four alien races at the Tower of Delicacy fight. It was certain that humans had won this round of fights at the small battlefield.
