Strength and Weaknesses

7 hours. 

Ethan was filled with frustration as he looked at Scarlett, who had a mocking expression on her face. He had lasted seven hours, but she was still filled with mockery.

They were wrapped in blankets and sitting on a couch. A projector beside them projected an old movie on the cave walls while a battery was charging it from the side. There was also a heater in the room that heated the surroundings. 

Her gaze still filled with mocking, she prodded her hubby's shoulder and said, "Even after we became cultivators. Listen, even after. Even. After. We became Colorless Halo cultivators, and even though it was you who started it—you could only last seven hours. Pitiful."

Ethan looked at her with a gaze as if he was looking at a deviant. Then, said craggily, "Fuck you. Even though I lasted only that short, while I was doing that, who was it screaming 'an, don't do it like that!' with an. I repeat. With an AHEGAO expression."
