Needless to say, it was Elder Bing, and also where Leo Ray left his trump card.
As a Chosen Son of God, Elder Bing's strength naturally surpassed that of ordinary strong men of the same tier. Coupled with a large number of Tier 6 cards given by Leo Ray, including many newly upgraded Tier 6 summon scrolls, it was most suitable to be used as a hidden trump card.
The reason Elder Bing took action was also due to Leo Ray's instructions.
Leo Ray clearly understood that if the explosion were allowed to occur, it would not only attract the attention of other opponents but also cause an extremely critical issue.
If these competitor family's giant dragons perished, even if Elder Bing reappeared, it would be difficult to break the Confinement Barrier in a short time. After all, we don't know the secrets of the Barrier, nor do we know the exact location of the Array Eye.
