"Ding dong."

"Warning, Conscious Probing is used for more than one minute, and continued use is a violation."

"Warning, Conscious Probing is used for more than one minute, and continued use is a violation."

Su Chen was nervously investigating the strange gasping sound, and when he heard the system's prompt, he gritted his teeth and retracted his consciousness.

"I'm going crazy."

Su Chen stomped his foot hard, resisting the urge to scold his mother in his heart, the cold voice of the system, at this time, kicked his tense nerves fiercely, but he had to endure hard. write.

But the strange thing is that after Su Chen regained consciousness, the strange gasping sound seemed to disappear, and he could no longer sense Bell's direction, and he didn't know whether Bell was aware of the danger.

He can only pray now that Bell's identity as a special soldier can give him enough self-protection ability, even if the strange gasping sound is from some underground beast, I hope Bell can persist until the moment he arrives.

Even so, Su Chen unconsciously accelerated his pace, because he couldn't use spiritual power and spells, and the sound of Su Chen's footsteps was especially obvious in the silent crypt.

Su Chen listened to the sound of his long-lost footsteps, had an idea, and deliberately increased his strength, and the sound of thumping footsteps was passed on.

The conditions for completing the lottery program were too harsh. Su Chen almost suppressed 80% of his strength. Fortunately, his physical strength could still be used, and his ear and smell were also extraordinary.

Su Chen took a big step because the strange gasping sound disappeared. Su Chen wanted to feel Bell as soon as possible. He listened to the movement around him and searched according to his previous memory.

He didn't know whether Bell would run into other crypt passages. Every time he encountered other crypt passage entrances, he would stop and carefully identify it to confirm whether there was Bell's smell.

About 10 minutes passed the time Su Chen had calculated in his heart, when he suddenly heard a slight sound coming from the front.

At first he thought it was the strange gasping sound, and hesitated for a while, but at that moment he heard it clearly, it was a subtle rubbing sound.

The sound was very similar to someone deliberately rubbing the ground with the soles of their shoes and moving slowly, appearing in a dimly lit crypt, a little weird.

However, compared to the rapid gasping sound before, this sound made Su Chen breathe a sigh of relief.

He was able to confirm that there was only one living person besides him in the crypt, and that was Bell, and the friction sound was probably Bell.

The sound of friction continued, and Su Chen quickly smelled a familiar breath and strode forward.

After walking about 50 meters, there was a bend in front of him. Su Chen reached out and touched the surface of the crypt passage. The hand was wet, but there was no sandy feeling.

At this time, the friction sound was in front of him. Su Chen was thinking about whether to say a word first. He was afraid that his sudden appearance would scare Bell. While he was hesitating, the friction sound suddenly disappeared, and then he heard someone The sound of breathing is approaching fast.

As soon as he turned around, he stood face to face with the person opposite, "Are you all right?"

Bell's breathing paused for a while, and then said calmly, "I know you are here, have you heard any strange noises?"

Su Chen said, "I found you just by following the strange voice."

Bell said, "What did you hear?"

"The sound of the soles rubbing against the ground," Su Chen smiled, "the quality of your shoes is very good, they have been rubbed for so long, and they haven't broken."

Bell looked down subconsciously and was stunned for a moment when he realized that his eyes were blacked out. He also laughed when he reacted, "I'm actually looking for air holes."

Su Chen asked curiously, "Blowholes? What blowholes? How come there are blowholes in this place?"

Bell didn't answer immediately. It seemed that he had confirmed it after carefully identifying what he was looking for for a long time. He said, "Guatemala has the largest underground cave in the world. Some people speculate that the underground cave here is connected to the earth's core."

guess?

Where are the seniors?

so imaginative

The distance between the earth's center and the surface is more than a Guatemalan crypt can connect

Su Chen shook his head, a little speechless, Bell couldn't see his expression clearly, and then said: "But this speculation has never been confirmed, but when someone came to Guatemala to explore before, he heard a strange voice, he said That voice is the voice of the heart of the earth."

"The voice of the heart of the earth?"

"That's right," Bell said. "It was a very strange sound, as if someone was gasping for breath. He thought of the speculation that the crypt was connected to the center of the earth, so he called the sound the voice of the center of the earth."

Su Chen said: "He can be sure that the sound is air flow? Wasn't it from some animal?"

Bell affirmed: "That person stayed in Guatemala for half a year just to wait for that voice. According to him, the voice appeared irregularly, but as long as it appeared, it would not disappear soon."

"Moreover, he once heard the voice beside him, and turned on the strong light searchlight, but he didn't find any living creatures. He only found a few finger-sized air holes on both sides of the crypt."

Su Chen said: "So you have been rubbing the ground before, just to find air holes."

"That's right," Bell said, rubbing his hands in annoyance, "I heard that sound just ten minutes ago, but when I fell off, I had a concussion, my hearing was not very sensitive, and my judgment was wrong. direction."

Su Chen sighed deeply, this person must have a strong heart to be able to find that inexplicable voice when he has a concussion.

An idea suddenly popped into his mind, Bell's willpower is so firm, if he cultivates, he will definitely give up his life, and he will never give up until he achieves his goal.

Su Chen told Bell that he did hear the strange sound, but thought it was an animal in the crypt, and didn't care that they were not far from the place where the sound appeared. If Bell wanted to go there, he could take him to find it. .

Of course Bell was willing, Su Chen took it directly to the place where the sound appeared before, and as soon as he got close, he heard the familiar gasping sound.

Bell said in a low voice, "God bless," he got down on the ground with his hands on the ground, and crawled over to that side.

Su Chen was also very curious about the voice, and only when he passed by did he find that Bell took out a roll of string from his backpack.
