This level is finally cleared.

With the help of the Eye of Darkness and Ding Yi's Overlord Golden Seal, the two joined forces and invited the Venerable God of the Sin Demon King into the dark world.

As for whether it is dead or not, it is none of Ding Yi's business.

He sat cross-legged in place and slowly regained his immortal qi while looking in all directions.

Boxes of fairy crystals were in front of him, and they didn't feel like they were illusory.

But what the hell is that black thing on the ground?

"This is the Demon King's Demon Core, a treasure that can be encountered but cannot be saved, as long as the Demon King of the Immortal Monarch level will have it. The Dark Eye didn't speak this time, as if he didn't have the strength to speak, but his will was transmitted to Ding Yi's mind.

"Legend has it that anyone who has cultivated the Demon King Demon Core will be able to be promoted to the Demon King of the Immortal Monarch level in the future, but the human race may be demonized, hahaha, it depends on whether you dare or not. Eyes of Darkness laughed.

In the history of the immortal world, few people dared to practice the Demon King Demon Core.

This is the same as the demon that Ding Yi encountered in the world, practicing the corpse of an immortal, and becoming a half-human and half-demon.

In the end, it may not please both sides, that is, it is not like a human being, and it is not like a demon.

But what is Ding Yi afraid of.

He used the elixir at that time, and legend has it that he will never be promoted to the immortal monarch.

Now that you practice this Demon King Demon Core, will you definitely be able to promote to Immortal Monarch?

The two laws are against the legend.

Who wins?

I care about you, Ding Yi has a horizontal heart, of course he has to fight.

After the Golden Immortal, there is no elixir that can be made quickly.

Relying entirely on his own cultivation, he doesn't have a single Wang Pin Immortal Crystal now, and his cultivation speed is slower than that of Heavenly Court.

Now that I have found such a good opportunity, of course I have to fight hard.

I don't care if I'm an immortal king or a demon king in the future, as long as I live.

Ding Yi waited for the immortal qi to recover, got up first, and put away all the boxes of top-grade immortal crystals in the hall.

Only then did he realize that the boxes made of unknown metal looked very high-end.

He was so excited that he took all the boxes and counted them, and there were really exactly a thousand boxes.

I opened a few boxes casually and took a look, each box was 10,000 top-grade immortal crystals, and the total number should be 10 million.

After the immortal crystals were finished, boom, a door appeared at the back of the hall.

The door slowly opened on its own, revealing a passageway.

At this time, Ding Yi was still more than twenty meters away from the gate, and he felt that there was a terrifying and mysterious power in the gate, with an incomparable aura.

"I'm grass. "This latter level is definitely even more terrifying.

It's not good, it's the immortal emperor level guarding the town.

What the hell is this place?

Ding Yi was still thinking about whether it would be left by Jiang Shen when he was an immortal monarch in the immortal world, but now look at it, this place is too terrifying, even Jiang Shen may die if he comes in when he is an immortal monarch.

An immortal monarch can reach the fourth level at most.

The fifth level doesn't even dare to enter the Eye of Darkness.

He was the one who defeated the Demon King of Sin.

Ding Yi didn't dare to stay for a long time, staying for a minute longer, he was afraid that something terrible would suddenly come out of that door.

He turned around and ran to the first floor in one go, finally calming down in his heart.

"Demon King Demon Core?" Ding Yi took out the Demon King Demon Core.

This demon core is pitch black, the size of a fist, a bit like the inner dan of a demon beast.

But the demon beast Neidan is a little soft, but the demon core is extremely hard.

I am only about 1.3 million immortal qi now, and I am still 700,000 short of 2 million in the middle stage of the Golden Immortal.

I don't know how much immortal energy is contained in this demon core?

Ding Yi did not hesitate, and sat cross-legged, holding the demon core in his hand.

Whew, a divine thought invaded it and began to practice.

"Boom"

Almost at the same time, a vast shadow rose in Ding Yi's mind, terrifying: "You humble human being, you dare to practice my demon core, I will let you turn into a demon, sink forever, and be my slave---"

The will of the Sin Demon King appeared strongly, and he was very unwilling to put out his last resistance.

"Woo" With his voice, endless demonic qi rolled around Ding Yi's body, and a large amount of demonic qi was also released in the demon core.

Infinite demonic energy surrounded Ding Yi and tried to penetrate his flesh.

In the midst of the demonic qi, whimpering everywhere, as if there were countless demons screaming and roaring, devouring the heavens and the earth.

Under normal circumstances, the human body of Ding Yi will soon be unbearable, first blackened, then demonized, and finally invaded by demonic energy, changing the texture of the body, producing scale armor or thick fur, and turning from a human to a demon.

In the future, slowly, with the transfer of time, human nature will become less and less, and the demonic nature will become stronger and stronger, and finally completely lose the function and humanity of human beings, and become a demonic monster that likes to eat raw and drink Maoru's blood.

The Sin Demon King in Ding Yi's mind was almost waiting to see Ding Yi's tragic situation.

He even thought that Ding Yi would beg his subordinates to show mercy for a while.

Then he can use Ding Yi's pressure to let the Dark Eye release his body out of the dark world.

But.

Boom, Ding Yi's body was like a huge vortex, and there was a sudden shock, and the demonic qi around him rolled in and was absorbed by him.

He didn't react at all, neither his expression nor his skin changed.

At the same time, the immortal qi in his body seemed to be boiling, and it skyrocketed wildly.

It's just the same as cultivating Wang Pin Immortal Crystal.

A piece of Wang Pin Immortal Crystal can increase 10,000 immortal qi.

Ding Yi is also in his body now.

Ten thousand, twenty thousand, thirty thousand.

Immortal energy is 10,000,000 increments.

The Sin Demon King and the Immortal Monarch are at the same level, and if they practiced before, they must also be spars like Wang Pin Immortal Crystals.

And the demon core is where his essence is, and Ding Yi is equivalent to absorbing his immortal qi (demonic qi).

Of course, this demon core can't have all his strength, it generally accounts for about fifty percent, and after being practiced, it is considered great luck to be able to absorb one percent.

Ding Yi didn't want to absorb one percent, as long as he could be promoted to the middle stage of the Golden Immortal, he would be satisfied.

This was the first time he had practiced a demon king-level demon core, and the requirements at that time were really not high.

The results were a bit unbelievable to him, though.

The immortal monarchs of the immortal realm, the lowest level of immortal monarchs, are all from one billion immortals.

The strength of the Sin Demon King is comparable to that of the Ten Immortal Monarchs of Heavenly Court, with at least 10 billion immortal qi.

The demon core accounts for fifty percent, that is, five billion.

Absorb one percent, which is also 50 million.

Therefore, Ding Yi's immortal qi is rising steadily, and after a while, he is approaching the two million mark.

"How is it possible, how is it possible---" The will of the Sin Demon King was shocked and frightened.

You are human, how can you practice our demon core? Why is there no demonization?

At this time, Ding Yi was still silent, and his immortal qi had quickly reached two million.

Two million is the middle stage of the Golden Immortal.

At this time, if you can't break through, the immortal qi will be fixed at this number.

And breakthroughs, half by chance, half by talent.

"Whew"

Ding Yi took a deep breath and felt that the magic core in his hand was still very large, and he could continue to use it.

Just about to put away the core.

"Boom" shook again in his mind.

"The Hand of Sin"

A text and a picture came to his mind.

It turned out to be the supreme magic skill of the Sin Demon King, the 'Hand of Sin'.

Ding Yi absorbed and refined his demon core, and even some of his memories and supernatural powers were all received.

This evil hand is very powerful, volleying into a big hand, catching the enemy, the basic realm is lower than his own, he can catch it with one move, and then he can directly pinch the opponent alive.

This supernatural power is probably similar to the Dragon Emperor Great Seal of the Dragon Realm.

However, the Dragon Emperor Great Seal can catch people who are stronger than themselves, and it is difficult for the evil hand to catch those who are stronger than themselves.

You can learn it, and Ding Yi immediately learned it.

Soon, he couldn't help but raise his right hand, volleyed in the air, and drew out one by one magic seals, bursts of immortal qi wrapped around his hands, the magic seals became more and more obvious, more and more skilled, and an invisible big hand slowly appeared in front of Ding Yi.

"How so?" the Will of the Demon King of Sin was about to go mad at the sight.

Ding Yi is not only absorbing his demonic energy, but also exerting his demonic skills.

This magic skill can only be used by gods and demons, and it is impossible for the human race to perform it.

Moreover, this magic skill is in Ding Yi's hands, releasing a large amount of immortal energy, like the supreme immortal technique of the fairy world.

It almost vomited blood and died.

"You're not human--- you're not human---- who the hell are you---" The Sin Demon King suddenly exclaimed.

"What?" Ding Yi, who was learning the hand of sin, shook his body when he heard this.

Boom, there was a thunderclap in his mind, like a sea bursting its banks, and the fairy qi was rolling.

Mid-Golden Immortal.

was actually frightened by the Sin Demon King, successfully broke through, and was promoted to the middle stage of the Golden Immortal.

Originally, his immortal qi was already two million, and he was ready to put away the demon core.

Ding Yi was overjoyed by this sudden promotion, and hurriedly straightened his body and held the demon core again.

The tide of immortal energy continued to be released from the demon core.
