After walking about a mile, a clear voice came to his ears, 'Coo, Coo, Coo......'. Out of curiosity, Fan Xiaoqi quickened his pace and continued to walk forward. After another hundred meters, he finally heard clearly, it was the sound of the water.

After continuing to walk forward for about fifty meters, he was pleasantly surprised to find a faint light that appeared and disappeared like a twinkling star not far ahead.

Finally, it's time to get to the exit!

While ecstatic, the blood of the beast boiled, he also discovered the source of the clear and pleasant sound of running water. It was an 'underground spring' that came out of the ground, about two or three meters wide. After the clear spring water gushed out of the ground, it formed a stream four or five meters wide, rushing in the direction of the light he had just seen.

The place where the underground spring appears is also the end of the tunnel. At this time, Fan Xiaoqi's surroundings were no longer walls cut from stones, but rough cave walls of different shapes. Caverns and tunnels are much more spacious than each other, with an average width of seven or eight meters and a height of more than ten meters. And its length, judging by the light that appeared and disappeared, should be within three hundred meters.

After seeing this delightful form clearly, Fan Xiaoqi continued to walk briskly towards his long-awaited goal, the exit of the cave.

Two hundred and fifty meters...... 200 meters...... One hundred and fifty meters...... As he got closer and closer to the entrance of the cave, the originally faint light became brighter and brighter, and Fan Xiaoqi's heartbeat and pace became faster and faster.

Finally, he walked to the entrance of the cave. As he was about to walk out of the cave, he stopped and peeked out a little. In fact, the outside of the cave entrance is not bright, but because of the full moon in the sky, the scenery on the ground is faintly visible. By the light of the moon, he made a slight observation. It was found that outside the entrance of the cave, in addition to the stream that rushed outward, there were only flowers and trees.

Just as he stood at the entrance of the cave for a moment to get used to it, ready to continue out of the hole. Not far from the entrance of the cave, there was a sound of talking from somewhere.

"Hello, young man. The voice of a man in his thirties said slowly in a relaxed tone.

Fan Xiaoqi was shocked in his heart, and retracted his half-stepped foot. And vigilantly made a defensive move, waiting for the speaker to appear or the next move.

Damn, is this a human or a ghost?......

His worries didn't last long. Because, the man who was in his thirties just now appeared immediately. He walked out of the hidden place in the bushes in front of the cave entrance, with a mysterious smile, and walked slowly with steady steps.

Fan Xiaoqi's eyes widened and he looked at the man carefully.

He was dressed in a light red gown, about 175 cm tall, with slightly broad shoulders, and his figure was neither fat nor thin. His face is very ordinary. If it weren't for the straight hooked nose under his eyes, I am afraid that most people, after seeing his appearance once, would have forgotten him completely in less than three days.

At this time, the man continued to smile, and asked him gently: "Hehe, you must not have expected that someone would be waiting for you here in advance, right?" As he spoke, he blinked his right eye lightly at Fan Xiaoqi, and then his smile became more contemptuous.

"Who are you? You, how do you know that I will come out of here?" Fan Xiaoqi stammered with a frightened expression.

"Don't panic, young man. Listen to me tell you slowly. The man in his thirties spread his hands, showing a look of indifference, and said in a leisurely tone. After a moment's pause, he continued, "First of all, I want to say that you are very lucky, very alert, and even ...... Clever. At this he paused again. And with his bright and confident eyes, he looked at Fan Xiaoqi's puzzled eyes. Then he said: "You were lucky enough to find the exit of the secret passage that had been sealed for a long time, and then when you entered, you carefully filled the pieces of garbage that you dug out of the secret passage, and filled it back almost perfectly." The man in his thirties paused again at this point, then smiled with shallow confidence, touched his chin with his hand, and continued, "However, you have overlooked a detail. That is, when you dig the dirt on the ground of the secret crossing with your hands, there are little dirt with maggots and your fingernail prints, and you don't notice them and hide them. So...... So you should understand by now, right?" After saying this, the man in his thirties spread his hands again and looked at Fan Xiaoqi with a relaxed smile.

Fan Xiaoqi stood still and didn't move, his eyes widened, his face full of doubts, and he listened attentively to what he said. Then, he stared nervously at this man, in his thirties, in a long horse coat. After thinking for a moment, he frowned, panting and said, "You, you, are you the ......?"

"That's right, I'm Yan Bing, nicknamed 'Flying Dog'!" the man in his thirties interrupted him, and said in a relaxed tone.

After hearing this, Fan Xiaoqi hung his head and sighed helplessly. He then fell into a brief period of contemplation. After a while, he raised his head sharply again, his eyes widened again, and he asked with a puzzled face, "Then how do you know that I am in this city?"

"Me?" hehe...... Yan Bing chuckled and said, "Actually, my thinking is also very simple, you fled on horseback to the southeast of 'Little Cow Village' after killing someone. In the southeast direction of Xiaoniu Village, there is only a relatively wide 'road', which leads to the 'Smoky Sand City'. So I sent someone to investigate the horseshoe prints on the 'road' leading to 'Smoky Sand City'. My men found and extracted horseshoe prints in several places where water had stagnated, identical to those you left outside the inn. So I guessed that you must have dared to come to the 'Smoky Sand City' to stay. Speaking of this, Yan Bing paused again, then showed a relaxed and confident smile, and then said, "As for ...... How did I notice the dump? It's simple. This 'smoky sand city' is one of the country's key tourist cities, with a beautiful environment and clean streets. There are hardly any, dark corners that can be used to hide. So I thought, if I had to find a place to hide, there would be only garbage dumps, stinking ditches, manure pits, etc. But, if I were you, if you were smart enough, you would definitely choose to hide in the garbage dump. Because the environment inside is relatively the best, and it can be hidden for the longest time. ”
