"Young Liu Yang, could you tell us what happened inside the mystical realm and how you managed to get out?" one of the old men asked.
All introduced themselves as elders of the China Cultivators Association. They wanted to know what happened to the Devourer Demon after everyone left.
"Well…" Liu Yang explained more generally than when speaking to his women.
Some parts were lies because he didn't want them to know about him being able to use the void power. The way he got out of the void was one of them, he just said there was a way out for the one who had the key.
The elders believe this because there seemed to be no other way out of the sect without the key.
The explanation was quick and easy to understand. The old ones understood some hidden things, but they didn't need to ask about it.
