"Then why didn't you go in right away?"
Fat Long, who had already come out of the small world, asked the Golden Core man.
"This..."
The man awkwardly said, "The ice was melting, and right after the entrance opened, someone heard the roar of the Fierce Beast inside. Also, through the fluctuation of spiritual energy, it was sensed to be around the fifth level of Golden Core."
"I'm only at the first level of Golden Core cultivation, so naturally I dared not enter."
...
"Brother Qiu."
Standing next to Chen Qiu, the scholar, squinting at the lit oil lamp on the inner wall of the passage, whispered, "That oil lamp is indeed a very old model. When it burns, black smoke drifts out, and it smells a bit like burnt roasted rabbit."
"That's 'fox oil'."
"A very common type of demon oil. Don't even talk about burning for thousands of years; without someone regularly refilling the demon oil, it wouldn't even last three months."
"It doesn't look like ancient ruins."
"Hmm."
