Tianxing walked forward with Yue Ying on his back for about a stick of incense, at this time, the vision in front of them gradually widened, the area of the cave became larger and larger, and they had unconsciously walked out of the damp and stuffy passage and came to a huge empty and open space.

The two of them looked up and carefully surveyed the place: it was a hollow, semicircular natural cavern, which looked much larger than the palace of the palace, and for some reason, the whole ground shimmered with a faint fluorescence, flickering and dimming.

Through this strange glimmer of light, the two of them could see that the walls around the cave were full of large and small openings, and the passage they walked out of was only one of them. In the distance, there was a hazy scene, with some milky white mist entwined in it, adding a few traces of mystery, and the bottom of the cavern was full of tiny hyphae that emitted a faint and eerie fluorescence.

Suddenly, Tianxing stopped, leaned forward to listen, and asked in disbelief, "Yue Ying, did you hear it?" There seems to be movement over there, as if there are a lot of people talking!"

"Young master, look ahead, that silhouette seems to be a city~?!" Yue Ying lay on the back of Tianxing, one hand pointed forward, there was the center of the cave, and there was a huge dark shadow standing at this time.

"Could it be that the ruins of the Ghost Clan we're looking for are ahead?" Tianxing looked excited.

"Then we'll have to be more careful. Yue Ying reminded.

Yue Ying climbed down from the back of the Celestial Star, was supported by the Celestial Star, and continued to move forward, gradually the shadow of the outline became clearer and clearer......

The old city is full of buildings and well-behaved streets. Perhaps it is too old, and the buildings are only vague in shape, and more of their appearance has been eroded by the wind.

Tianxing and Yue Ying looked at the buildings in the city curiously, and the closer they got to it, the stronger the sense of strangeness became.

All the houses here are low, as tall as children, and the streets are narrow and cramped, not like a place for humans to live. The walls of the house were all covered with ravines and uneven dirt, like air-dried vents, black holes, like the eyes of monsters, watching the intruder faintly.

"Young Master, the architectural style here is too weird, isn't it?" Yue Ying couldn't help but ask in a low voice.

Tianxing also looked puzzled, and walked for most of the day, but he didn't see a single figure.

The strange atmosphere that has been indescribable makes Tian and Yue more and more strange, is this an empty city? But just now I heard the sound of people boiling here.....

Thinking of this, Yue Ying couldn't help but shudder, and said suspiciously, "Could this really be a ghost town?"

Looking at the silence around him, Tianxing couldn't help but get goosebumps, and he leaned over to the side of the house with the courage to look in through the bowl-sized vent, but unfortunately the light was too dim to see anything clearly.

"Shh~!" Yue Ying suddenly booed, lowered his voice and said, "Young Master, listen~!"

Tianxing immediately listened around, and at this time, there was a distant cry of 'Si Xi Suosuo~ squeak' in the distance behind him.

The faces of the two changed at the same time, "It's not good, those toothed light rats have caught up~!"

"What should I do, hurry up and find a place to hide~!" Tianxing pulled Yue Ying and rushed to the roof on the side, and after climbing the roof of four or five floors in a row, and after reaching the highest place, he took a big breath, helped Yue Ying to sit down, and then cautiously looked at the ground below, which was nearly three zhang high from the ground at this time.

At this time, Tianxing looked at the other side of the house with the fluorescence of the mycelium on the ground, and found that there was actually a circular altar in the center of this strange underground ancient city.

There is a clay statue on the altar, and I don't know how it was mixed with something, but there is a sour and rotten smell, which spreads out and erodes the sense of smell on the human body.

Tianxing wrinkled his nose, and an unpleasant thought flashed through his mind: Isn't this smell the smell of the human body after decay?

Moreover, for some reason, Tianxing always felt that he was alive when he saw that statue, especially the pair of black hole eyes, when he first touched it, he couldn't help but feel that people were shivering, and he always felt that those cold and empty eyes were cold, as if he was staring at himself.

In front of the altar, there are also some unseen tributes, including white eggs like steamed buns, and mushroom-shaped meat...... , in short, some food that has never been seen before.

On the side of the clay statue, there is also a huge tripod, Tianxing feels a little familiar when it first looks, when it sees its appearance and color clearly, it can't help but be surprised, almost shouts, a huge blue copper tripod, the tripod body is covered with water lines, and there are four ghost heads, it is: "Shadow Spirit Seal Ding~!!"

At this time, the sound of squeaking, from far and near from outside this ancient city, "squeak squeak - squeak squeak——......"

The creepy rustling grew louder and more uniform, as if a multitude of things were approaching the city in a neat stride.

Tianxing turned over and peeked out of the roof of the house, looked at the voice, and found that it was a dense network of rats, and most of the bodies of those toothed rats were covered with unknown slime.

Tianxing and Yue Ying suddenly felt their scalps tingle, and it was hard to imagine that thousands of hungry rats were swarming densely like sticky ink, "Damn, fortunately I climbed fast, otherwise I would definitely be gnawed by these toothed rats to the point that there are no bones left." Yue Ying and Tianxing were afraid for a while, and kept cursing.

In the face of so many rats pouring into the ancient city together, even Tianxing and Yue Ying, who were lying on the highest place, were a little overwhelmed, so they had to hide carefully here, hoping to avoid this group of rat army, but if these toothed rats stayed for a long time, even in this highest place, it was difficult to guarantee that they would not be discovered, and the two of them were helpless for a while, so they had to keep praying that God could have the virtue of a good life and help themselves avoid this difficulty, even if they died in battle, it was better than dying in the belly of the rat.

"Is it my delusion? Why do I feel that the ground is shaking?" Yue Ying suddenly opened his eyes, touched the roof under him, and said with some doubts.

Listening to Yue Ying's words, Tianxing also felt that the roof under him trembled slightly, as if it was an earthquake. However, I always feel that this vibration is very regular, as if it follows a certain rhythm.

"It's not like an earthquake, it seems that something is not quite right~!" Tianxing seemed to catch some other dangerous information from the shaking of the ground, and reminded Yue Ying in a low voice.

"Click~Click~Click~Click~Click!"

As soon as Tianxing's words fell, he heard a sound in the ancient city that was louder than the movement of the toothed light rat.

The uniform sound was magnified tenfold in the underground cavern, like several horse-drawn carriages speeding together, approaching.

"Click~Click~Click~Click~Click!"

As each sound fell, the ground also shook, and finally the owner of the sound appeared~!

The unimaginable terrifying scene that followed made Tianxing and Yue Ying open their mouths wide, and they didn't dare to take a breath, lying on the roof and not daring to move at all.

I saw that the ancient city, which had been dead and silent just now, suddenly boiled, and one by one, the borers as thick as buckets crawled out of the vents in those strange buildings in all directions, and there was even a nose almost attached to the star, poking its head out of the hole below.

They glared fiercely at everything below, as if they were planning a terrible attack on the toothed rats that slept on their territory.

Tianxing couldn't believe his eyes, the loud noise that shook the mountains just now turned out to be made by this one borer! Could it be that he had just come out of the rat's nest and entered the worm's nest?

Presumably, these borers are the real rulers of this underground ancient city~!

One by one, the rulers of these ancient cities tilted their heads, revealing blood-red palates, on which were long mouthparts as sharp as scissors, which opened and closed with sharp mouthparts that hummed like human whispers softly.

"I see~!" Tianxing secretly said in his heart: "The voices of those people I heard at the gate of the ancient city before are this voice! It turned out to be made by these borers~! We actually stepped on their doorstep just now and climbed up, and we are afraid to think about it~!"

"No~, you can't stay here for a long time, you must find a chance to slip away quickly~!" Yue Ying said cautiously when he saw this scene.

"Where are you going? Once your whereabouts are exposed, you can put them at will, and you won't have anything left for us to eat, if they rush up, we won't even be able to plug our teeth~, let's stay here honestly. Tianxing gave Yue Ying a resentful look.

Thinking of this, the hearts of the two suddenly tightened, filled with fear, and involuntarily got closer and closer, and finally hugged each other.

At this moment, the borer, which was only a foot away from the celestial star, raised its sharp palate, as if blowing the horn of attack, and in an instant, all the borers rushed out of those houses and launched a fierce attack!

They wielded their mouthparts and crawled towards the dense toothed mice, greedily swallowing them into their stomachs.

At the same time, those toothed light rats who were originally staring at this ancient city immediately sensed the danger, and quickly fixed the target of the attack, and then swarmed up, just a few breaths, these borers became crawling with black pressure tooth light rats.

"Damn, won't you?" Yue Ying and Tianxing looked at each other in disbelief.

Tianxing blinked, his forehead covered with sweat and muttered: "Could it be that this group of toothed light rats chasing us closely~, is the nemesis that we and Yue Ying have been trying to find and suppress the borer?~!!"

Yue Ying nodded, "Looks ...... It seems like this......"......
