Thor didn't mind her grumpy tone. He even grinned and summoned his golem as he replied provocatively, "You know what I want."
Princess sneered and said to him, "Aren't you that loser that I defeated without being able to resist? Are you here for another round of beating? Are you a masochist?"
Thor didn't get angry because of what she said. He calmly brought out the energy shield projected and activated it. A pale golden glow appeared around him. This gave him the confidence to go ahead with his plan.
Actually, he couldn't become angry because he didn't have the right to become angry. Her words were true too. If he doesn't have something that gives him the right to challenge her, then he would simply be repeating his earlier defeat.
But now that the shield had been activated, he felt confident enough to retort, "We will see who likes a beating very soon."
