This secret passage is much longer than the one I walked before and has a downward tilt.

At first, Zheng Songru was still thinking about the distance and direction in his mind, but after walking for about half an hour, he found that the passage was not straight, but had a curve. It was precisely because of this curve that the light could never shine too far.

The castle is located in summer, and both of them are extremely thin, especially now, they come out of the bedroom and are just wearing a nightgown.

As they went deeper, the more they could feel the biting cold all over their bodies, making them tremble as they walked.

Zheng Songru is better, after all, he practices martial arts hard, practices in the winter and in the summer. Although he cannot be said to be completely unafraid of the cold, his ability to resist the cold is still much stronger than Xu Mingguang.

Xu Mingguang is a pampered young master. The location of Xiangjiang is also very warm all year round. How did he suffer such a hardship?

As he walked, Zheng Songru could hear his teeth fighting and his body trembling violently.

Seeing this situation, Zheng Songru was also secretly worried, and even suggested going back. After all, in his opinion, no secret is as important as the body. At that time, Zheng Songru had already noticed that the cold was very abnormal, and probably it was not just the low temperature.

But Xu Mingguang really seemed to be unable to suffer, but he had to persist. His backbone look made Zheng Songru a little admired.

So Zheng Songru helped him and the two walked downstairs together.

Because he was cold and extremely nervous about the things below, Zheng Songru's nerves were always tense and in a state of high tension. At the beginning, he could calculate how far he had walked. Later, he felt that his mind seemed to be frozen and could only walk forward blindly.

At that time, Zheng Songru felt a sense in his heart that he and Xu Mingguang seemed to be wandering around in circles under the valley, as if this was a huge, spiral-shaped downward passage, like no end.

In this deep and open passage, everything around was extremely quiet, and it was almost dead silent. The two of them could hear each other's breathing and heartbeat, which added a bit of weirdness to the atmosphere.

It was precisely because of the silence here that when Zheng Songru heard some sounds in his ears, he thought he had hallucinations.

Some subtle sounds of moaning and crying were faintly heard into his ears, and it felt like a sudden burst of time in his mind, as if this sound could ting his brain.

At the same time, Xu Mingguang's slightly fearful voice sounded in Zheng Songru's ears: "Did you hear any sound?"

Only then did Zheng Songru dare to believe that this voice was not an illusion of his own, but a real existence.

As we walked along the way, the two of them could talk to each other at first, but at this moment there was no communication at all and they just walked forward blindly. At this time, Xu Mingguang spoke to Zheng Songru, with a hint of hoarseness in his voice.

Zheng Songru did not respond too much, but just said "um".

Then the two of them closed their mouths again, and they usually stopped talking about this matter with a tacit understanding, but just walked forward.

It’s not that I don’t want to say it or that I have no strength at all. But at this moment, there is a feeling of inexplicable fear in my heart. Once anyone raises this topic, it is very likely that the two of them will turn around and run away.

As the two continued to move forward, the faint moans and crying seemed to become clearer, but they were still close and distant, and they were not very clear.

Then, Zheng Songru could feel the wind rising in this passage.

This situation is extremely unusual.

For a sealed underground passage, it is impossible to have a large-scale air flow, and it is even more impossible to form wind.

Although the temperature in this passage was particularly low, it made them feel extremely cold, but there was no cold wind blowing until now. At this moment, the cold wind blew their exposed ankles and arms, making them feel even colder.

Just when Zheng Songru had already felt a deep regret and wanted to think about leaving Xu Mingguang, at that moment, he suddenly realized something was wrong, stopped suddenly, and grabbed Xu Mingguang beside him.

He shuddered heavily.

Xu Mingguang opened his mouth and gasped. In that moment, he felt a creepy feeling after a disaster.

Just in front of the two of them, a huge fault appeared, like a broken wall of a cliff appeared, with darkness below and no bottom visible, because the passage was extremely dark and the flashlight was too faint, the cliff could not be seen at all.

If Zheng Songru hadn't felt that the wind suddenly increased in this position, he would have probably stepped on it.

After standing on the edge of the cliff for a while, Xu Mingguang still did not give up. He held a flashlight in his hand and shouted Zheng Songru, moving along the edge of the cliff, wanting to see if he could go around.

But after walking for a long time, the cliff seemed to be extremely long and had no end at all.

Zheng Songru calculated the path of his walking and drew a route in his mind. He was surprised to find that what the two of them were actually in a nearly round shape.

In other words, this is not a cliff at all, but a huge black hole.

This black hole is the size of a football field, and the cold wind and intermittent moans and crying sounds are all heard from under the hole.

However, moaning and crying must have been caused by the wind passing through the caves that might exist under the black hole.

Xie Mingguang originally thought that this secret passage was related to the witchcraft in the ancient castle, but unexpectedly, he only saw a huge black hole. After a brief shock, he couldn't help but feel a little disappointed.

He thought, maybe there was a secret under the hole, so he tried every means to go down and take a look.

However, because the black hole is too deep, the flashlight cannot be shined at all. It is impossible to go down rashly if you can't figure out how deep the hole is.

In order to find out the depth of the huge hole, Xu Mingguang finally decided to throw a flashlight down.

After the flashlight fell into the black hole, the two of them watched helplessly, waiting for the moment when the sound of landing was heard.

But the flashlight was spinning in the air and fell all the way, and the light of the flashlight also rotated, gradually becoming smaller and disappearing.

But in the end, the last sound of falling sounded.
