Archie was groaning in pain as he turned himself back to his human form and tried to get rid of it. He didn't want to use his other hand because it was dangerous so he kept swinging his arm but it didn't do anything.
"I can't get rid of it, Eve, cut my arm off!" Archie said while he felt an immense amount of pain from the corrosion on his arms.
Eve looked at Archie's hand which was slowly melting and she immediately cut it off without hesitation. It was so fast and clean that Archie didn't even feel anything until his blood came out from his shoulder.
Archie sighed with relief as his arm slowly grew back and looked at his sword which looked fine even though it was smeared with phlegm. He didn't know what to do but he didn't want to leave his sword behind so he grabbed the handle where it didn't smear with phlegm.
"Be careful, Eve, you might injure yourself," Archie said as he held his shoulder.
