The creature's internal juices mixed with its blood, creating a putrid mixture that burned away at Lucius's skin. Even though the creature's internals had been torn to shreds, its body continued to swallow him, inching him further into its stomach.
Lucius didn't have it in him to cast another solar burst and have enough solar energy left to heal himself, so he tried to pull out the needle spear from his back, fighting against the creature's stomach muscles. He thrust his needle at the fleshy walls, before sticking both his hands through the hole and tearing it wide open.
The creature shrieked, trying its best to regurgitate him, but its throat muscles were in too much disarray to follow instructions, and Lucius continued to stab holes within it. All the while his skin was burning, he held on, making the creature regret every second of trying to devour him.
