The Bond beasts left for the Mountain of Dragons as soon as they delivered the message of surrender. Lu Li had not regained consciousness yet so Patriarch of Law Enforcement did not take any rash actions. He told Master of Fairy Fox to keep the situation stable for now and not to engage in battles any time soon.
