"Kill Lin Qingxue and cultivate to a triple ascension!"

Suddenly, a line of handwriting appeared on the Book of Demons.

Thundered~

When the voice fell, surging power suddenly rushed out from the Book of Demon Dao, flowing around Gu Yin's body in an instant, pushing his cultivation.

Boom!

That power was incomparably powerful, and in less than three breaths, Gu Yin's cultivation was pushed to the eighteenth peak of the Quenching Blood Realm, and forcibly broke the shackles of the Quenching Blood Realm and stepped into a higher Bone Forging Realm.

A moment later, when the last trace of strength was exhausted, Gu Yin's cultivation stabilized at the third level of the Forging Bone Realm.

At this moment, he was full of strength!

For this result, Gu Yin is very satisfied.

"The Book of the Demon Dao is really magical, just killing the person recorded on it, and in a moment, my cultivation has been raised by three realms, which is worth at least eight years of penance for ordinary people. ”

"As long as I continue to kill Tianjiao, the strong, and the big people with prominent status in the future, then my cultivation will be able to improve quickly, and I don't need to cultivate by myself at all. ”

"Killing, it's really a shortcut to cultivation......"

Feeling the surging power in his body, the corners of Gu Yin's mouth couldn't help but bloom with a faint smile.

The golden finger of the Book of the Demon Dao is definitely enough to defy the sky!

As long as he goes all the way, one day he Gu Yin will definitely become the most terrifying, murderous, and powerful killing god in this desolate world, making all beings fearful.

At that time, he will also be above the heavenly beings, immortal and immortal.

Thinking of such a scene, a sense of pride suddenly rose in Gu Yin's chest, and his eyes were also surging with fierce murderous intent in his eyes.

"Who's next?"

Successfully killing Lin Qingxue, Gu Yin took out the Book of Demon Dao with curiosity, and then gently opened it.

I saw that on the Book of Demon Dao, Lin Qingxue's name had been crossed out, and the word 'death' was marked in scarlet characters below, but the rest of her names were not revealed behind her name.

Seeing this scene, Gu Yin couldn't help frowning.

"I guess it's not time yet......"

Looking at the blank Book of the Demon Dao, Gu Yin secretly guessed.

As he spoke, he prepared to close the Book of Demons.

Crash~

However, at this moment, a cold and ruthless voice suddenly sounded.

"Successfully kill the first genius and reward a ...... Killing Demon Knife"

Shout!

When the voice fell, suddenly, a brilliant black light rushed out from the Book of Demon Dao, turning into a simple black knife suspended in front of Gu Yin.

The black knife is about four feet long, and the blade is outlined with mysterious patterns and lines, and the wisps of black light flow along the lines, which seem to contain boundless ferocity and sin.

In addition, there was still a black dragon lying horizontally where the back of the knife was connected to the handle of the knife, releasing boundless killing power and hideousness, just by looking at it, Gu Yin felt an overwhelming murderous aura coming towards him.

Even, faintly, he heard the terrible screams of countless creatures......

This is a magic knife tainted with boundless killing and sin!

Its existence is enough to make the creatures of the world tremble.

However, Gu Yin likes it!

"The Killing Demon Knife is destined to be born for killing......"

Between muttering, Gu Yin raised his hand and gently grasped the handle of the knife.

Buzzing~

The moment he held the hilt, the originally silent magic knife suddenly bloomed with a brilliant black light, and then, a wave of world-shattering killing machines swept out like a flood, engulfing Gu Yin in an instant.

However, because of the existence of the Book of Demons, Gu Yin was not affected in any way, but gave him a magical feeling of being at home.

At the same time, following that terrifying murderous aura, information about the Killing Demon Knife was also automatically presented in Gu Yin's mind.

Name: Killing Demon Knife

Grade: God

Introduction: The supreme divine weapon born from the origin of killing, the only one in the world, as long as the master of the magic knife is strong enough, it can take you to slaughter the gods of the heavens.

Evaluation: The only one in the world!

Note: The Killing Demon Knife was born out of the endless years of the evolution of the Killing Origin, and it is one of the top divine weapons in heaven and earth, and the first owner is, Gu Yin.

The Demon Knife of Killing has three god-level attributes:

1. It is invincible, nothing in the world can stop its edge, and defense in front of the Killing Demon Knife is a joke.

2. Into the demon, once the master of the demon knife enters the state of entering the demon, he can obtain a powerful power beyond his own three small realms, and at the same time, he will temporarily fall into the demon path, and the offensive will not stop without killing the enemy completely.

The price of entering the demon: After entering the demon, if you kill an enemy who cultivates to three small realms higher than yourself, you will be devoured by the magic knife for a certain lifespan, and the stronger the enemy you kill, the more lifespan you will devour.

3. The unity of the human knife, the body of the knife, from this person is the knife, the knife is the person, not bound by the formation, prohibition, coercion, space, speed first.

......

All the information of the Killing Demon Knife was presented in front of Gu Yin.

Call~

After reading it, Gu Yin couldn't help clenching his fists, and his eyes bloomed with a bright divine light.

"The Killing Demon Knife is worthy of the name of the Divine Soldier. ”

"With it, all living beings in this world can be killed by me!"

Gu Yin looked up to the sky and laughed.

The power of the Killing Demon Sword was beyond his cognition and imagination, especially the three god-level attributes, which made Gu Yin's heart surge.

Each of them can be called against the sky!

The three god-level attributes are gathered together, and it is difficult for anyone in this world to kill him, but he will become a nightmare for all living beings.

Before, Gu Yin was still worried that his combat power was not strong enough, but now he didn't need it, with the Killing Demon Sword in his hand, even the most powerful existence in Qingyang City could not pose a threat to him.

There is just one thing that makes Gu Yin quite jealous.

That is, the second attribute of the Killing Demon Knife!

As long as the enemy's strength surpasses the three small realms of Gu Yin, then once he enters the state of entering the demon, he will start to attack endlessly until he completely kills the enemy.

He couldn't control it at all, and he couldn't stop attacking.

In addition, the cost of killing enemies beyond their own three small realms is also very large, and they actually have to be devoured for a certain lifespan, and the stronger the enemy killed, the more lifespan they will devour.

Three small realms are a red line!

Once it is surpassed, it will inevitably pay a huge price.

For example, Gu Yin encountered an enemy who surpassed his own one great realm one day, then he had to think carefully about entering the demon, relying on the power of the Killing Demon Knife, even if he could kill the enemy, but the life span of the final devouring would be very terrifying.

If Gu Yin's lifespan is devoured, then he may die!

The consequences were not something he could bear.

Thinking of this, Gu Yin's expression suddenly became much more solemn.

"It seems that you will have to use it carefully in the future......"

Looking at the Killing Demon Knife in his hand, Gu Yin sighed secretly.

Everything in the world, there are advantages and disadvantages.

Within the rules, you can play as you please, and once you exceed the rules, then you have to pay the price.

Gu Yin naturally understands this truth.

Since the Killing Demon Knife had the restrictions of three small realms, Gu Yin naturally had to abide by it.

Thinking of this, Gu Yin glanced at the Killing Demon Knife, and then his mind moved, and the Killing Demon Knife instantly turned into a streamer and entered his body.

In the end, he was quietly suspended above the dantian, and while receiving the nourishment of spiritual power, he was also removing the impurities inside, making the spiritual power more and more refined.

After doing all this, Gu Yin immediately prepared to find a place to wait for the master of the Lin family to come to retaliate, however, just as he took a step, a sad roar suddenly sounded in his ears.

Then, he saw a guard come to him with a sad face.

"Young master, the master is gone, woo woo ......"

The voice of grief reached Gu Yin's ears.

Guzhen Tian died?

Suddenly hearing this news, Gu Yin was stunned, and his expression became complicated.

"Lead the way!"

With a casual order, Gu Yin followed the guards and left.

Although he didn't have any feelings for Gu Zhentian in his heart, it was his nominal father after all, and he had to go and see it.

About a quarter of an hour later, Gu Yin stopped in front of a quaint courtyard......
