Poof!

In the pitch-black cavern, there is a huge black heart buried here, and the root of all demonic energy comes from here.

Above the heart, there is a Pu Demon Tree, which is using its demonic energy to strengthen its body.

On the side, Qing Xuanyue looked at this scene, and couldn't help but be shocked, he had mixed feelings in his heart, in order to pursue martial arts, he did not hesitate to cling to the Pu Demon Tree, and now it has caused the leakage of demonic energy.

"If you are not ruthless, it is difficult to achieve great things!"

Qing Xuanyue clenched her fists and said secretly. With his qualifications, there is no hope of becoming a saint, but now with the help of the power of the Pu Demon Tree, he has become a saint. With his character, he will not hesitate to sacrifice the Ten Domains!

"Blue Moon"

At this time, the voice of the Pu Demon Tree came out.

"The subordinates are here!"

Qing Xuanyue came back to her senses and arched her hand.

"There's one more thing for you to do for me, and there must be no mistake in this one. ”

The Pu Demon Tree was gloomy, and the sticky black demonic energy was wrapped between the branches.

Buzz –

At this time, I saw a token levitating and landing in the palm of Qing Xuanyue's hand, and the front of the blood-red token was engraved with the word "demon".

"It's ......"

Qing Xuanyue frowned, this evil thing didn't seem to be a good thing.

"It will take some time for this seat to refine the Demon Heart, so I can't let Su Yuan interfere with me. Therefore, I need you to unleash the four evils for me, create turmoil, and make him unskilled. ”

Pu Demon Tree's voice was low and strange.

"Four...... The Four Murderers?"

Qing Xuanyue didn't seem to understand.

"On this vast continent, there were four strong people, they became demons because they devoured the demon heart, and they were extremely vicious, and later, they were sealed here by the powerful people. This token can break the seal and make it hear. ”

Pu Moshu's tone was a little depressed.

"The master is me, let me unleash the four murders, create chaos, and make Su Yuan have no skills?"

Qing Xuanyue heard the meaning.

"Yes, these four murderers are all extremely vicious people, and they are immortal beings, so they are sealed here, you go. ”

The Pu Demon Tree was full of demonic energy.

"This ......"

Qing Xuanyue hesitated, if he really released the monster, then he would be a sinner through the ages, he originally just wanted to gain strength, but he didn't expect that it was difficult to ride a horse now, and he couldn't turn back.

"Yes!"

After struggling inwardly, Qing Xuanyue gritted her teeth and nodded. Since there is no turning back for him, he can only continue to make mistakes.

......

Brush –

In the north, here is a barren Gobi desert, sparse weeds, and a dead silence in the air. In the middle of this area, there stands a stone monument.

"Demon Suppression Monument"

Qing Xuanyue levitated down and landed not far away, looking up at this stone tablet. The stele has been slowly molded with the years, and it is already very old, and the surrounding area has been overgrown with weeds. Located on the body of the stele, there is also a brown rune paper.

Buzz –

At this time, Qing Xuanyue poured magic power into the token, and the token projected a ray of light, which instantly shone on the rune paper. The magic light corroded, and with a snort, the spirit rune was actually burned by the demon fire!

Rumble!

The entire stele shook violently, and the billowing black monster rushed out from the bottom of the stele!

Click-

Finally, the stele couldn't be suppressed, and it actually cracked one after another.

Bang, bang bang!

The billowing dust leaked, the demonic qi surged in all directions, and with a wave of Qing Xuanyue's sleeve robe, it immediately landed on the side of the collapsed stone tablet, and in this huge pit, he dug out a box.

A black wooden box.

In the wooden box, demonic energy is coming out, and at the same time there is a squeaking sound, it seems to be a mouse!

"This is the sealed Rat Emperor. ”

Qing Xuanyue swallowed a mouthful of spit, looking at the spirit rune on the box, as long as he uncovered this spirit rune, he would be able to release the Rat Emperor!

The Four Ancient Murderers, the Scale King, the Rat Emperor, the Stone Maiden, and the Heavenly Demon Moth, in order to pursue strength, later devoured the Demon Heart and became a monster, and obtained the power to penetrate the heavens and the earth, and were later sealed here.

And this wooden box is called the rat cupboard.

It is a natal magic weapon of the Rat Emperor, and there are endless mice hidden in the rat cupboard, once the rat cupboard is opened, it will cause a terrifying catastrophe. These rats are not only bone-eater, but also highly poisonous!

When the rat cabinet was opened, countless bone-eating rats waded across a continent, and the corpses were scattered across the field, devouring all human beings and trees in an instant!

Qing Xuanyue was in a cold sweat on his forehead, he had no turning back, and gritted his teeth.

Snort –

The runes are burned!

With a creak, the rat cupboard opened.

A wisp of black smoke emerges.

"Huh?"

After being quiet for a long time, Qing Xuanyue glanced towards the rat cupboard.

Squeak squeak!

A shrill cry rang out.

He found that in the rat cupboard, red pupils lit up.

Boom Boom –

At this moment, the rat cabinet shook!

Huhuhu~

Qing Xuanyue's face turned pale with fright, and she immediately quickly retreated, located in the rat cupboard, a black torrent rolled out, and these black torrents were the bone eater rats in the rat cupboard!

Squeak squeak!

These bone-eaters are the size of a palm, covered in black hair, with a narrow mouth, sharp teeth, and red pupils.

Rumble!

The moment the rat cabinet opened, almost millions, tens of millions of bone eater rats rushed out, and if the rat cabinet was not closed, then the bone eater rats would gush out in an endless stream!

"This ......"

Qing Xuanyue snorted coldly, because, where the black torrent passed, it was instantly gnawed into ruins, such a powerful quantity, almost in an instant, everything was devoured, tree roots, grass roots, spirit beasts, all living beings!

Huhuhuhu-

And the Bone Eater Rat is spreading in all directions, and at this speed, I'm afraid it won't take a few hours to reach the Ten Domains!

This will cause a terrible catastrophe!

Snort –

At this time, in the rat cupboard, wisps of black gas rose, and at the same time, a breath that made the heavens tremble and the earth collapsed gushed out, rumbling, and the sky was thundering!

Countless black thunderbolts intertwined, and the billowing black mist rose, and a figure appeared in the black mist.

The figure had the body of a human, but its head was a rat with scarlet pupils. He was dressed in a shabby black robe, as if he had been eaten, his red eyes were extremely shrewd, and a few whiskers made him look even more gloomy!

"Bendi has finally come out......"

The Rat Emperor's voice was sharp and piercing......

......

Rumble –

It was also on this day that a catastrophe affected the entire vast continent. Within the Ten Domains, wherever the bone-eating rats passed, all living beings were gnawed into a pile of white bones, and countless cities were tragically passed by the rats. And those wooded mountains were also eaten bare.

"What's going on?"

The Great Yuan Dynasty, suddenly, the sound of shaking made the capital rumble and tremble. It's not the sound of an earthquake, it's the sound of the rat army moving!!

Rumble –

Not far away, a torrent of black came......
