Chapter 1669: What’s Wrong?

Occasionally, Gu Xijiu and Di Fuyi would exit the underground and go to the surface to take a few breaths. They attentively checked the traces which clearly showed that they were on the right path.

Executing the Aqua Drilling technique was very physically draining. Even though Gu Xijiu's spiritual power was already very advanced, her physical capability was still incomparable to Di Fuyi's. 

Toward the end, it was Di Fuyi who did everything; blowing the magic shell and checking the ripples. Gu Xijiu was only following him around.

Perhaps she had been in the underground waterway for too long. Gu Xijiu started to feel a pain in her stomach. It started mildly at first, but it gradually became more severe. It could be her menstrual pain, but if it were, then it would be the severest of its kind.

It was as though a knife was slowly slashing through her internals. She was in such great pain that she broke out in cold sweats.
