It was the first time in her life when Dongmei was clearly panicking at this point. She quickly swam downwards, rejecting any thoughts of Wuxing's death which started appearing inside of her mind. He couldn't die, he wouldn't leave her like that. Dongmei repeated that in her head and with only that thought driving her, she dived deeper quickly reaching the tunnel.
Bonk.
Just as she entered the tunnel, her forehead hit something hard and it hurt her really badly. She clutched her head immediately on instinct, rubbing her forehead to smooth the pain, but then she looked at what she hit and it was Wuxing she was so worried about.
