The tree branches that held Byung let him go despite this not being an action of Papadopoulos. Everyone in the arena felt the killing intent and the examiner momentarily thought to stop it but this would go against the rules because despite this killing intent, the precautions have already been put into place to prevent outright death but he had a very bad feeling about this.
"This energy!" Dohyun thought to himself, it was far more sinister than what they experienced when it manifested itself during the sealing and it will be a disaster if Byung rampaged right here and now despite prominent guild members being present. He was not sure they will be enough to stop him, but the seal should hold if anything else.
Byung's feet touched the ground and the branches that had him in their grasps moments ago writhed and died, and instinctively the Guild Masters observing in the arena tensed up because they felt threatened. Nobody should be able to emit such a powerful killing intent, nobody.
