Aerial
The average cultivation base of the opponents he would have to face at once was at the mid 7th Lique stage.
This may not seem like much, considering how strong Jason was, but every single of the 49 opponents in the first round of the battle royale was extremely strong, allowing them to reach an average combat prowess of the 10th Lique stage!!
If every single one of them would attack him at once, Jason wouldn't have a way to emerge victoriously.
However, he had already set up a plan, which allowed him to make use of the large number of different races that should have been told to attack him first!
Unfortunately, attacking someone with a total of 48 other individuals couldn't be described as the most intelligent move, which was what Jason wanted to make use of.
The races inside the arena were the Hrans, Klarirs, Dragonewts, IIlians, and the demi-human races called Tigron, Hamaa, Fyrmn, and Lizr.
