In the valley, there is a very simple door, illusory, hidden from time to time.

The door shone with a rustic gray light, and there was a breath of time flowing in it, which looked extremely extraordinary.

And in front of this illusory door, there stood dozens of Terran monks in black robes.

Each monk held a circle plate in his hand, and in the midst of the array, spiritual light constantly flew out and merged into the looming door.

Under the effect of these spiritual lights, it can be clearly felt that the gray light above the door is slowly being worn away, and the entity of the door is gradually solidifying.

These monks should be the underworld monks of Lu Qingshan.

The King of the West Rat secretly pondered, didn't think about it anymore, and according to Lu Qingshan's instructions, he took out the photo beads and silently recorded the scene in front of him.

After a while, the King of the West Rat put away the photo beads, satisfied, and was about to leave here.

At this time, there was some movement in the valley, which made the king of the West Rat stagnant.

In its keen perception, just now, it actually felt that among those black-robed monks, on one of the monks, there was suddenly a faint but unusual aura fluctuation that flickered away.

The West Rat King is not quite sure, whether it is his own delusion or a real breath fluctuation.

But the next moment, the King of the West Rat was clear.

Because, the black-robed monk stopped his movements very coincidentally, and he didn't know what to do with those demon beasts entrenched in the valley, and he left the valley like this.

"There must be a ghost!" The Rat King noticed the clue, but he hesitated a little, "Do you want to go with me to see what the situation is?" ”

After hesitating for a moment, in the end, the West Rat King still couldn't hold back the curiosity in his heart.

"As long as I have some heart, I should not be discovered......." The Rat King began to act while calming himself in his heart.

It leapt from the ancient tree it was hidden in, turned into a gray shadow, and hung fearfully behind the black-robed monk.

But what the King of the West Rat didn't know was that just after it followed the black-robed monk, in the valley, the black rat that seemed to be closing its eyes and recuperating suddenly opened its eyes and stared closely at the direction of the King of the West Rat's departure, with its nose moving slightly.

"This is the breath of my rat demon vein?"

The breed of the black rat is the gold eater rat, the gold eater rat is good at the art of earth escape, can swallow metal ore, absorb the energy in the ore, and continue to evolve, which is an extremely rare rat demon bloodline.

In addition to the ability to devour metal ores, the Gold Eater Rat also has the ability to explore ore veins with one hand, relying on its innate strong nose sense and perception of metal minerals.

And just now, at the moment when the West Rat King flashed by, it smelled a smell that belonged to the Rat Demon.

"This is the land, after our Demon Spirit Palace and those Terrans' investigations, how could the breath of a strange rat demon suddenly appear?" The black rat had some doubts in his heart, but he didn't directly inform others of his discovery, but found an excuse, and followed the faint breath that had faded in the air.

The Rat King followed the black-robed monk for a long distance, all the way to the back of the valley.

It scanned suspiciously at the empty rock wall in front of it, which was covered with dense scratches, as if it had been scratched with an instrument.

Other than that, nothing is unremarkable, and nothing anomalous exists.

"Why are people gone?"

Because of the fear of being discovered, the Western Rat King has always maintained a very long distance from the black-robed monk, relying only on his outstanding perception ability to hang far behind.

It's just that the aura of the black-robed monk has disappeared here in an extremely strange way.

"Huh?" The Rat King scratched his head, "Have you lost it?" ”

Boom!

A dull voice suddenly sounded at this moment.

Before the West Rat King could react, he felt a huge force restrain it, and then took it into a gray shadow, and quickly merged into a rock on the side, hiding in shape.

And in the next moment, on the ordinary rock wall, there were suddenly bursts of ripples, and a purple circle of light slowly spread.

The Rat King's eyes widened.

It's a scene he's seen before, it's very familiar!

This is exactly the same as the scene of the Void Demon activating the spatial teleportation ability!

Then, the black-robed monk who had just been lost and dozens of strange Terran monks appeared from this purple circle of light.

At the same time, a fierce killing aura burst out from that purple circle of light, marking dozens of shallow marks on the stone wall.

The Rat King could even catch a glimpse of the inside of the aperture, which was a dark and secluded hall, and there were several jade pillars in the hall, and many ancient demon characters were carved on the jade pillars.

"How's it going?" The black-robed monk put away the purple bead in his hand, and the purple circle of light on the stone wall disappeared with it.

"The tomb of the Gengjin Tiger King has been found, but outside his tomb, there are several layers of powerful barriers, and it will take us a while to break it." One of the Friars in purple stepped forward in response.

"Speed up a little faster, we won't be able to delay too long on the front side, at most we can buy you another half a month to a month.

If it drags on any longer, the beasts in the Demon Spirit Palace, even if they don't have brains, they can probably see that something is wrong. The black-robed monk snapped.

"The killing aura emitted by the Gengjin Tiger King is too strong, and it has a great impact on our spirits, and we have to leave the tomb every once in a while, otherwise we will lose our minds.

In this way, it has seriously affected our progress, otherwise it would not have dragged on for so long. The Friar explained.

Looking around, you can find dozens of Terran monks on the field, and their eyes are all scarlet at this time, which is extremely weird!

......

At this time, the Western Rat King did not pay much attention to these underworld monks, but turned back among the rocks with difficulty, wanting to see what he had been captured.

It's just that as soon as he turned his head like this, the king of the West Rat was frightened.

It turned out to be the black rat demon I had glimpsed in the valley earlier!

The Rat Demon made a silent gesture to the Rat King.

The King of the West Rat cooperated very well.

Time passes slowly, and every minute and second is like torment for the king of the western rats.

Finally, another half of the time passed.

When the scarlet color in the eyes of those purple-clothed monks all dissipated and returned to clarity, the black-robed monks took out the purple spirit bead again, pinched the trick and cast a spell, and a spiritual light suddenly appeared on the purple spirit bead, which melted into the stone wall, and then a purple circle of light slowly dispersed.

"Time is running out, you guys finish the task as soon as possible!" The black-robed monk's tone was very deep.

"Understood!" The purple-clothed monk replied softly, and then one by one, the fish rushed in.

When the last person also entered the hall in the circle of light, the black-robed monk put away the spirit bead, and the shadow turned into a streamer of light, and disappeared in front of the stone wall.

A moment later.

Thump!

Two rat demons squeezed out of the rocks.

Lu Qingshan, I'm afraid that Lord Rat is going to be righteous for your bravery, what do you owe me, what do you want to pay!

The King of the West Rat looked at the black rat aggrievedly and helplessly, not understanding how he was discovered, and he was very frightened.

The eyes of the black rat were full of inexplicable meaning, and he looked at the king of the West Rat, and said suspiciously: "What kind of rat demon are you?" And how do you feel like you haven't seen it in the Demon Spirit Mountain Range before? ”

The heart of the West Rat King was tightly hanging, and this time it was immediately put down.

It is good at observing words and feelings, and from the tone and content of the black rat's questioning, it can be seen at once that this black rat has no bad intentions for it.

"I don't know ...... either" The West Rat King's acting skills broke out, and he said with trembling teeth: "I have never seen you in the Demon Spirit Mountain Range before......"

The black rat pondered for a moment, and when he saw that the King of the West Rat looked trembling, he stretched out his mouse paw and rubbed the red mane on the head of the King of the West Rat, and said comfortingly: "Don't be afraid, my name is Rat Ba, and I am the strongest rat demon in the Rat Demon Demon Vein in the Demon Spirit Mountain Range."

Our rat demon vein has always been weak, and we are at the bottom of the monster food chain, so we need to support each other very much.

Therefore, after I advanced to the third grade, I was the strongest person in the Rat Demon lineage, and I have always been sheltering the weak Rat Demon Lineage.

Although I don't know what breed of rat demon you are, since you belong to the line of rat demons, you can be regarded as my child.

I see that you seem to be a bit supernatural, not like a mortal thing, in this way, you will follow me in the future, maybe I can cultivate a third-grade demon beast for the rat demon lineage. ”

"Squeak, squeak." The King of the West Rat replied weakly and helplessly, not daring to object.

Rat Ba nodded with satisfaction.

"Where did those Terrans come from?" The King of the Western Rat, who accepted his fate, turned his mind around, and immediately pointed to the location where the monk of the underworld had just disappeared, and asked with an innocent expression.

Rat Ba's voice suddenly sank, and he said: "You are also the lucky star of this king, if it weren't for the fact that I just smelled your breath and chased after me, I would definitely not have discovered this shocking secret." ”
