The cave reverted to its previous scene, the sound of gurgling water flowed in my ears, and there was a faint wave of light refracting the light at the end of the open cave, as if there was a rushing river in the distance, silently waiting for the arrival of the three of them.

Through the darkness, Zhu Beichen covered his red and swollen eyes, and he was the only one among the three who knew that Yan had existed here, she had been here, and she had disappeared here. Squeezed out a smile at the boundless black curtain and warned himself to get out alive: "Let's go, listen to the sound There is a river ahead." I've always doubted the depth of the Sun Tomb, it stands to reason that at such a deep depth, it should have been in contact with the underground water source a long time ago, and there should be an underground river ahead. ”

Where there is water, there will be life, and it may be possible to find live fish to solve the current food problem.

The sound of the water is getting louder and louder, and the water source is getting closer and closer, and the three of them are silent all the way, each with their own thoughts, only the sound of rushing water resounds.

"Let's talk, you guys are so quiet, as a fat man, my heart is overloaded, and I can't pee with you at all." Fat people can't stand loneliness the most, especially in a team of three, this emotion can be depressing, and in a state of hunger, communication can effectively relieve the hunger of the limbs.

Han Qingxin took over the conversation and said: "I heard that the disappearance of the sand-buried ancient city is inseparable from the sandstorm, and the deterioration of the environment and the disappearance of water sources have forced the aborigines of the ancient city to leave the ancient city. ”

Zhu Beichen was stunned for a moment, still thinking about the departure of the mourner, everything here is inseparable from the main theme of death, including the disappearance of the ancient city is shrouded in the shadow of death, he is a little helpless, and said with a sad face: "Are you sure you are not talking about the ancient Loulan, the disappearance of the ancient city of Loulan is speculated by relevant experts to be caused by the disappearance of water sources caused by desertification, and the ancient city of Shabu and the ancient city of Loulan may be caused by the difference in cultural names caused by different years, and they can refer to the same place." ”

Why didn't you think of such an obvious connection before? Zhu Beichen suddenly felt that the ancient city of Loulan had been discovered, and it was not in the same place as the Sun Tomb, could it be that the deterioration of the living environment caused the ancient Loulan people to move the city they lived in to the lower strata, and the huge construction of the Sun Tomb was to protect the ancient city underground?

The sound of flowing water is like a guzheng playing a seductive melody, guiding those who explore the mysteries of the ancient city to the stratum and to the unknown secret place.

The idea that Gulou Lancheng was actually under the stratum also startled Zhu Beichen, who had a whim. So, are there still humans living in the city?

The place where the water source exists meets the most basic living conditions, and although the underground river in the cave is only heard and nowhere to be seen, it does exist. Does it show from the side that there is really an amazing underground ancient city buried here?

The fat man raised his eyebrows, as if chewing on Zhu Beichen's assertion, it is true that everyone's thoughts are unique, but no one is so radical as to assert the existence of the underground ancient city: "Hehe, you haven't thought that the Loulan ruins on the ground are real, and the sand-buried ancient city is also true." ”

The two ancient cities were inhabited by the same indigenous people, and during the Han Dynasty, did the Loulan people have the ability to open up a huge underground structure?

Ha~~hehe~~

The laughter was very soft, always afraid of disturbing the creatures in the cave, but it fell on Zhu Beichen's ears very clearly, the voice was very familiar, the voice was soft, and it was sure to be a female voice.

"Is that you?" He asked softly in his heart, and then cautiously glanced at Han Qingxin and the fat man beside him, and saw that both of them had a contemplative expression, and their attention was on the four walls of the cave, and they didn't seem to hear any women's laughter at all, so he put his mind at ease.

However, the doubts in my heart became heavier, "I must have hallucinated, the death no longer exists, her fate is over, and it is impossible to appear again." ”

"This is an ancient city!" Zhu Beichen's scalp was numb, and he suddenly chuckled, the voice was expressing a sentence, how could it be an illusion?

Zhu Beichen asked silently, "Death, is it you?" Aren't you really dead yet? "The emotions are complicated, faintly with a hint of excitement, and with worries, why there are variables. Is there a variable, is it a change in some kind of pace? Is this a good thing or a bad thing?

"Uh-huh." The voice replied clearly, and the tone was no longer as cold as before, but a slightly teasing and joyful tone.

She didn't understand what was going on, all the soul nails were removed by Zhu Beichen, and in her memories before her death, the wizard had inadvertently revealed it once. The dream of heavenly desire is an unsolvable array, but things in the world reciprocate and regenerate, and there is no absolute.

Death needs to meet a "living dead" to remove the soul nail in order to be liberated, and the so-called liberation is to disappear forever. The probability of a person with a numerology physique like Zhu Beichen appearing in the world is too low and too low, and the possibility of appearing in the cave is basically zero.

In short, all the contingencies come together.

"Actually, I don't understand what happened, when you removed the last soul nail, a scorching wave of air suddenly rose in the space I was in, and my body was blown to pieces. I really thought I was going to fall here, but I didn't think I would survive. ”

Oh, the words of the martyr sounded impeccable, and the extremely suspicious Zhu Beichen didn't dare to believe it completely, and always felt that the martyr had deceived or concealed something.

After experiencing a bizarre event, her heart has changed inexplicably, and she is like a sixteen-year-old girl, and her giggles are always accompanied by her every word, "I was born here, I have lived in a huge city since I was a child, and there is an ancient altar in a corner of our city." She pointed to where the dark cavern came from.

The number of altars in the ancient city of sand burial is extremely large, and the scale of the altars is different, symbolizing the belief and respect for the "witch culture" in the ancient city. She had never walked around the ancient city due to special reasons, and she could only tell Zhu Beichen that the altar was located in a corner of the ancient city, and this long cave was once part of the ancient city.

Zhu Beichen asked, "You mean, we are now in the ancient city you are talking about?" ”

Yan smiled slightly and replied, "You can say so. I've also heard others say that there are 81 passages in our ancient city that can lead to the outside world, and there will be altars in each passage. Don't ask me about the role, I really don't know. ”

There are as many as 81 exits from the ancient city to the outside world? Zhu Beichen obtained enough information in the description of the funeral, an ancient city has a maximum of eight gates to enter and exit according to the layout, but the residents of the ancient city use passages, and the ancient city with eighty-one passages is laid. It is conceivable that the scale of the ancient city is magnificent, and it also shows from the side that the ancient city buildings do not exist on the ground.
