"Don't be kidding, we have to get down to business now, if we can't complete the task assigned by our senior sister as soon as possible, it will not only affect her plan, but also more likely to let the people of the Demon Domain seize the opportunity and be in a favorable position in this competition. Either way, the consequences are undoubtedly beyond our reach. Marlena said with a serious face.

Hearing this, Caiyun immediately nodded in agreement, and the two came to a high ground to the west of the abyss, standing on the highest point and looking down, everything that came into their eyes surprised Caiyun.

Although the abyss is a hilly area with uneven terrain, the ups and downs are not very drastic, and the whole of the abyss can be seen at a glance from the highest point. But since an incident a hundred years ago, the landscape of the abyss has changed dramatically.

A thick mist that can only be found in the deep mountains and old forests began to rise over this area, enveloping the entire barren abyss for a long time. Walking in the wilderness of today, one will find that the visible distance is barely more than a foot, even compared to a cave where you can't see your fingers, and even those with an excellent sense of direction can easily lose themselves in this fog barrier, and find their way to the future.

Just by doing so, the abyss can be turned into a desolate place that no one cares about, but the dangers here don't stop there. In the midst of that fog barrier, from time to time, strange whirlpools of air suddenly appeared, each whirlpool contained an endless amount of suction, so powerful that it could crush all the creatures that approached it into powder, and then swallow it into the whirlpool.

The disciples of the Holy Yao Sect conveyed a warning to the inhabitants near the abyss and told them the cause of the formation of the whirlpools of air currents.

It turns out that these whirlpools are not cyclone-like air currents, but a very special phenomenon.

That's because a powerful psionic energy that exceeds the load of space can only occur when pressure is exerted on this area, and the space is overwhelmed and gradually collapsed by years of oppression. At first, only small cracks are formed that are difficult to see with the naked eye, but later they become a spatial vortex like a large mouth of blood.

Space is being torn apart alive by spiritual power, what a terrifying sight is this?

Caiyun couldn't help but sigh from the bottom of his heart: "The spiritual power of the Dragon God is really amazing, and the invisible influence can easily reach this level, I'm afraid it's about to catch up with the natural calamity-level spells." ”

Marina bowed slightly, and said with a hint of concern: "It seems that our exploration may be very difficult this time, I don't know if we can go smoothly, and I don't know if we can get a satisfactory answer." ”

"What should we do next, it seems too dangerous to enter the abyss directly, although the strength of the two of us is indeed not weak, but it is difficult to ensure that it is foolproof in the realm covered by the spiritual power of the dragon god. Caiyun's eyes were also full of worry, and her thoughts wavered, not knowing how to proceed with her next plan.

"Let me use the underground water source to probe the scene below before deciding what to do next. ”

After saying that, Marina began to concentrate, precipitating the distracting thoughts in her consciousness, and entering a state of extreme tranquility in which she forgot about things and herself. Her spiritual power began to slowly release from her body, gradually passing through the thick fog

, infiltrating the earth. With the fluctuation of spiritual power, Marina's consciousness is also spreading, following her spiritual power to the underground, becoming her second pair of eyes, taking her to observe everything that is happening underground.

When Marina's consciousness merges with the clear water flowing underground, a new world is unveiling the mysteries it has hidden for thousands of years before her eyes.

Marina opened her eyes and observed her surroundings, and suddenly realized that the water she was manipulating did not come from the small underground ditch she remembered, but a small winding river.

Although there is no light in the ground, there is only darkness forever, but it does not mean that it is all dirty and cluttered. Although there was a slight smell of decay in the air, it was not pungent. And the scene of rocks and dust did not appear in front of me.

The rivers are clear, the surface is clean, and the rumored underground chaos is not there at all.

Although it is dim, the field of view is not wide enough. But at the end of the river, you can still clearly see a wall more than five feet high standing in front of you.

Even a strong-willed and calm person like Marlena couldn't help but be horrified the moment she saw the wall.

"Why is there a city in this underground? Could it be that I'm hallucinating? It's impossible. ”

Marlena froze her mind and looked at it several times, and after making sure that it was indeed a very large wall, she immediately stripped her consciousness from the water.

"How's it going?

Marina's face was very serious at the moment, and she said in a deep voice: "Caiyun, our task this time may be very difficult. ”

"What's wrong? Is there something unusual going on underground?" Caiyun felt Marina's tone and knew something was wrong, and a sense of foreboding hit her.

"The structure beneath this abyss is unlike any other, and there may be a very large ruin hidden. Marlena said with a solemn face.

"Ruins? Shouldn't the dragon mound be a ruin? What's so strange about that?"

Caiyun was confused, and his face was full of confusion, as if he didn't know what Marlena was trying to say.

"The dragon mound is indeed a ruin, but it should be easy to feel the breath of the dragon god there. However, directly below where we were, the aura of the dragon god was not obvious, and it could even be said that it was nothing. But I could clearly see a huge wall about five feet high towering in front of me. ”

From Marina's words, you can clearly feel the horror and surprise that was churning in her heart when she saw the wall.

It is quite possible that this wall represents a buried civilization, an erased history, a country submerged by the river of time. There are many unknown secrets waiting to be discovered, and Marlena and Caiyun are undoubtedly the pioneers in unraveling the mystery of this history.

"The city walls? You say the ruins are a city? Caiyun also shouted in surprise at this time.

Marina made a low-voice gesture to Caiyun and said, "

We try not to be too public, so as not to be targeted by the eyes of the Demon Domain, which will affect our plans. ”

Hearing this, Caiyun immediately nodded, made his volume as low as possible, and whispered: "Are you sure? ”

Marina then explained to Caiyun, "I've confirmed it many times, and I can't be mistaken. In fact, it is not impossible for a city to be buried in the ground, as long as the city is old enough, there is a chance that a similar situation will occur. After the city was deserted, after thousands of years of vicissitudes, some serious natural disasters may have a great impact on the environment of this area, and it is not impossible to change the original geological structure. ”

"I see, can you tell how old that city is?" asked Caiyun curiously.

"I don't really know much about this knowledge, but I can make basic judgments through some natural factors, anyway, there is definitely a history of 5,000 years, maybe even longer. Marina analyzed seriously.

"Oh my God, I'm only seven thousand years old, is this city even older than me?" Caiyun said in surprise.

"You're not serious again, we're talking about business. What's more, your age is not calculated in this way, there is almost no concept of time in the outer heavens, and the seven thousand years you have spent are almost immeasurable to the people of this world, and there is no difference from eternity. When Marlena saw that Caiyun began to joke again, she said angrily.

Caiyun hurriedly put away her hippie smile and continued to ask questions.

"So the dragon mound might just be a part of this ruin?"

"Well said, in a word, exactly as I thought. I think that if you want to confirm the location of the dragon mound, it may not be enough to rely on the longitudinal water technique alone, after all, the underground structure is so complex that it is easy to lose its direction. Marina said solemnly.

"So what should we do next?"

"You always throw this kind of question to me, and you don't have to think about it with your smart mind, no wonder Nuwa Niangniang keeps saying that you are not motivated. Marlena said in a "reproachful" tone.

"Cortana, you also know that my Huigen is actually very shallow, and my mind is not bright at all, so I can't compare with you and Miss. Caiyun said coquettishly.

"Alas, I don't know why Nuwa Niangniang took you as an apprentice in the first place, it's really strange. Marina sighed.

Caiyun smiled coquettishly: "Maybe it's because my appearance is alluring to the country and the city, and my character is also extraordinary." ”

"I think it's because you're born with the nature of a servant, and you can do whatever you want without complaining in your heart. ”

The two looked at each other, and suddenly they all covered their mouths and laughed.

Marina is actually a very demure lady, but whenever she is with Caiyun, she is always infected by her, and unconsciously begins to joke meaninglessly and mix words, making the atmosphere between the two happy. Caiyun is such a lovely girl who can bring laughter to everyone around her, and her talent and temperament are indeed far superior to ordinary monks, but this may be the real reason why Nuwa Niangniang admires her.
