"I just seemed to hear that sound again." Qiong suddenly said during the climb.

"Voice?" Fan Ning's hands and feet didn't stop, and the echoes of the two people's conversation overlapped in this narrow space.

"I heard it too..." Sheeran at the top said, "On the day of the graduation ceremony, before we discovered the existence of the secret door, we heard the sound while staying in the activity hall on the first floor."

Fan Ning remembered: "It's like a dense sound made by some kind of sharp object? It's strange, I haven't heard it before, and I still haven't heard it now."

Is there any difference between Xilan and Qiong? Or is this a polluting gibberish emanating from an unknown existence, blocked by some of his own characteristics?

"As soon as you feel something is wrong, you must speak up immediately." Fan Ning reminded.

"I understand... I haven't noticed it yet. I feel like it has always been just noise."

As we went down, the odor remained strong, but there was no sense of shortness of breath. This indicated that there was either a vent somewhere, or that the space was large enough to consume the oxygen of three people in a short period of time.

To a negligible extent, there are no other sources of biological consumption or pollution.

The temperature is obviously getting colder and colder. It used to be a bit stuffy for the people who were wearing tight clothes, and their skin was sweating a lot. But now the moisture has evaporated, and the body feels dry and cool, making people feel the feeling of autumn in advance.

This is not surprising. In a place similar to a basement structure, it is normal for the temperature difference to exceed ten degrees. However, Fan Ning felt that the well seemed a bit too deep. He kept counting the steps of the escalator on the well wall.

It is now level 610. According to the distribution density of level one of about half a meter, the location where the three of them are currently is already 300 meters deep.

"Caron, why did you stop?" After passing dozens of steps, Joan accidentally stepped on Fan Ning's hand that was on the escalator.

"There is something on the wall of the well here." Fan Ning said.

Between the two bricks on his left hand side, a twisted bronze-like object protruded.

Above her head, Qiong squatted down, and after shining a flashlight up, she could see that it was in the shape of a groove.

"Candlestick?" Fan Ning saw that the bronze hollow floral decoration around the groove was very complicated, stacked up unevenly in layers, and some places were stained with red or white marks - because people's subconscious mind will distinguish the protruding parts of the object.

Thinking about the combination of facial features, this looks like an expressionless face composed of red eyes, red nose, and white lips.

What kind of weird aesthetic style? Fan Ning couldn't figure it out, but he still said loudly: "Qiong, turn off the flashlight, the use time of this thing is too short."

He hooked his arm on the escalator and groped behind with his other hand. He took out one of the more than twenty tallow candles and put it into the groove. The temperature slowly reversed and the wick flame ignited.

After walking down the dark vertical passage for a long time, even though Fan Ning's spiritual sense was strong, his vision was a bit depressing. After a candle was placed on the wall, the light slightly alleviated this discomfort.

After the candles were lit, Joan spoke the next moment:

"Caron, there seems to be something behind you."
