When Jin returned from the dungeon instance he had created, he was not particularly surprised at the entire Bearling Capital in ruins. The night was still young but the burning from his initial destruction as well as the damage caused by the Mecha Dragons was in a huge mess. Yet, he did not feel any regret doing any of all these mainly due to the fact that he knew this was all just a Virtual Simulation to occupy the inhabitant's mind.
Still, it does rub him off the wrong way thinking that this might happen to his world if the Celestial would ever attack him and that was only when Kraft mentioned that word to him before disappearing. It would have been fine if the Celestials had hit Pandapolis or Demopolis where all the combatants there were able to resurrect and live to fight another day.
