Chapter 2540: Only One Can Live

"What happened? Is it because of the mushrooms?" Han Sen pointed at the plants that were on both of their heads.

Gu Qingcheng shook her head. "I told you, I'm not a person of the modern age. I am a Qi Gong user of ancient times."

"So is this happening because of your lifespan?" Han Sen's heart jumped. Gu Qingcheng was the same as him; both of them had entered a crystallizer control room. When Gu Qingcheng had left the control room, she had been transported tens of thousands of years beyond the period in which she had been born. She had entered a world that was completely different from the one she knew.

If they calculated the time that had passed while she was in the control room, Gu Qingcheng should have died a long time ago.

Gu Qingcheng nodded, then shook her head. "It is because of my lifespan, but it is not as you think. It isn't because I entered a crystallizer control room."

"Then, what is it?" Han Sen asked in concern.
