Walking through the sea of fire, unaffected, was Compass Carburettor. As he was in his Haggon form, he now understood just how powerful it was. Just the rigidity of his skin prevented the heat from affecting him.
It was not to mention the fact that any minor burns automatically healed. He wasn't expending much Darlac since he was only walking through the paths where the fires had almost died out.
It was the safest spot since the grass hadn't begun to grow yet while the fire wasn't hot enough to waste more of his Darlac.
He couldn't rush fast, for that would make him reach the patch of grass that had yet to be burned by the fire. So, he couldn't rush things through. But, it was a torturing experience, especially since he now had enough time to think, causing him to worry about Grisha.
