The Dragon Binding Lock is so powerful because it is directly linked to the ninety-nine Dragon Balls within the dragon's body. Once entangled, external energy cannot enter the body; instead, all of it is absorbed by the Chain Dragon. Although one can struggle, the sturdiness of the Chain Dragon, supported by the ninety-nine Dragon Balls, undoubtedly makes it impossible for any opponent of the same rank to break free!
When energy replenishment is cut off and all internal energy is drained, death is almost certain. Devoid of energy, even the largest dragon is no different from meat on the chopping board, ready to be carved.
Of course, the Dragon Binding Lock is not invincible. It's a terrible fate to get caught by it, but catching someone is required for it to be effective. If the opponent were Xin Yun, Yi Luo Xiang, or Yan Qingying, it would be nearly impossible to ensnare them.
