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

There was a simple gray light shining on the hall door, and there was a breath of years flowing in it. It looked very extraordinary.

In front of the illusory gate stood dozens of human friars in black robes.

Each friar holds an array plate in his own hand. In the array plate, there are constantly spiritual lights flying out and integrated into the looming door of the temple.

Under the action of these spiritual lights, we can clearly feel that the gray light on the hall door is being slowly rubbed away, and the entity of the hall door is gradually solidified.

These friars should be the underground friars mentioned by Lu Qingshan.

The king of the West mouse thought about it secretly. He no longer thought about it. 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 westmouse put away the photo beads, was satisfied and was about to leave here.

At this time, something happened in the valley, which made the king of the West mouse stagnant.

In its keen perception, just for a moment, it unexpectedly felt that there was a faint but unusual breath wave on one of the black robed friars.

The Western mouse king is not sure whether it is his own illusion or the real breath fluctuation.

But the next moment, the West mouse king will know.

Because the black robed friar, by coincidence, stopped his action. I don't know what he said to those monsters entrenched in the valley, and he left the valley like this.

"There must be a ghost!" King westmouse noticed the clue, but hesitated. "Do you want to go with him to see what the situation is?"

After hesitating for a moment, the king of westmouse still couldn't restrain his curiosity.

"As long as I'm careful, I won't be found..." King westmouse comforted himself and began to take action.

It jumped down from the ancient wood where it was hiding, turned into a gray shadow, and hung behind the black robed monk with fear.

But what king westmouse didn't know was that just after it followed the friars in black robes, in the valley, the black mouse, who seemed to be closing his eyes, suddenly opened his eyes, stared at the direction of King westmouse's departure, and the wings of his nose moved.

"Is this the breath of my rat demon?"

The variety of black rat is golden rat. Golden rat can swallow metal ore, absorb the energy in the ore and evolve continuously. It is an extremely rare rat demon blood.

In addition to the ability to devour metal ores, golden eating rats also have the ability to explore mineral veins, relying on their innate nose and perception of metal minerals.

Just now, in the flash of the West mouse king, he smelled the smell of the rat demon.

"This is a forbidden area. After a lot of investigation by our demon palace and those Terrans, how can the smell of strange rat demons suddenly appear?" the black mouse had some doubts in his heart, but he didn't directly inform others of his discovery. Instead, he found an excuse and followed the faint smell that was going to fade in the air.

King Nishimura followed the black robed friar for a long way, all the way to the back of the valley.

King westmouse glanced at the empty rock wall in front of him in doubt. There were dense scratches on the rock wall, as if they had been scratched with an instrument.

In addition, everything is ordinary and there is no abnormality.

"Why are people gone?"

For fear of being discovered, King westmouse kept a long distance from the black robed friars and hung far behind only by relying on his outstanding perception ability.

But the smell of black robed friars disappeared here in a very strange way.

"Eh?" the West mouse king scratched his head, "have you lost it?"

Dong!

A dull voice suddenly sounded at this time.

Before the king of the West mouse reacted, he felt a great force clamp it down, and then took it into a gray shadow. He quickly integrated into a rock to hide his body.

At the next moment, on the flat rock wall, waves suddenly flickered, and a purple aperture slowly spread.

The king mouse stared.

This scene has been seen before. It looks very familiar!

This is the same as the scene of the nether demon's ability to launch space transmission!

Then, the black robed friar who had just disappeared and dozens of strange Terran friars appeared from the purple aperture.

At the same time, a fierce cutting spirit also burst out of the purple circle and made several marks on the stone wall.

King westmouse could even catch a glimpse of the scene inside the aperture. It was a dark hall. There were several jade pillars in the hall, on which many ancient demon characters were carved.

"How's it going?" the black robed friar put away the purple bead in his hand, and then the purple aperture on the stone wall disappeared.

"We have found the tomb of King Geng Jinhu, but there are several layers of strong prohibition barriers outside his tomb. It will take us some time to break it." one of the purple friars stepped forward and replied.

"Speed up the speed a little more. We can't wait too long on the front side. At most, we can buy you another half to one month.

If you drag on, even if the beasts in the demon palace have no brains, they may see something wrong. "The black robed friar snapped.

"The spirit of killing and cutting emitted by the Geng golden tiger king is too strong. We have to leave the grave every once in a while, or we will lose our mind. In this way, it will seriously slow down our exploration progress," explained the friar in purple.

Looking around, dozens of Terran friars can be found with scarlet eyes!

......

However, at this time, the king of the West mouse did not want to pay more attention to these underground friars, but turned back in the difficult rock to see what he was captured.

Just such a turn, the king of westmouse was scared to death.

It was the black rat demon I had seen in the valley!

The rat demon made a silent gesture to the West mouse king.

The king mouse cooperated with each other wisely.

……

Time goes by slowly. Every minute and every second is like suffering for the king of westmouse.

Finally, after a long time, when the scarlet color in the eyes of the purple friars dispersed and the Qingming Festival was restored, the black friars took out the Purple Pearl again, and a purple aperture appeared in the stone wall again.

"Time is running out, you finish the task as soon as possible!" the black robed Friar's tone was very gloomy.

"Understand!" the purple friar whispered, and then one by one.

When the last person also entered the hall in the aperture, the black robed friar put away the spirit beads, turned his figure into a streamer and disappeared in front of the stone wall.

A moment later.

Plop!

Two rat demons squeezed out of the rock.

The black mouse's eyes were full of inexplicable meaning. He looked at the West mouse king and said suspiciously, "what kind of rat demon are you? And how do you feel that you haven't seen it in the demon mountain before?"

The king of the West mouse was relieved immediately. He was good at observing his words and colors. He immediately saw that the black mouse should have no bad thoughts about it.

"I don't know..." the West mouse king's acting broke out and said with trembling teeth: "I've never seen the mouse king in the demon mountain before. How about you..."

After pondering for a moment, the black mouse saw the king of the West mouse trembling, stretched out his paw and rubbed the red mane on the king's head, and comforted: "don't be afraid, my name is rat batian. I'm the strongest rat demon in the vein of rat demons in the demon mountain.

We rat demons have always been weak and are at the bottom of the monster food chain, so we need to support each other very much.

I have been sheltering the weak rat demon since I advanced the third grade.

Although I don't know what kind of rat demon you are, it looks very strange and not ordinary.

In this way, you will follow me in the future. You may be able to train a third grade monster for the mouse demon. "

"Squeaky squeaky." the West mouse king replied weakly and helplessly, not daring to object.

Rat batian nodded with satisfaction.

"What was the origin of those Terrans just now?" the king of the West mouse, turning his mind, immediately pointed to the location where the underground friars had just disappeared and asked with a pure face.

Rat batian's voice suddenly sank and said, "you are also the king's lucky star. If you hadn't just smelled your breath and followed me, I wouldn't have found this amazing secret."
