Doomsday: At the beginning, I was stuck with a system bug and killed a super god

"My name is Li Yu. A few months ago, I was an ordinary high school student."

"Due to some factors, now, there is an existence called Demon God in front of me, who wants to make me a legendary villain!"

"But there are drawbacks to the help of this demon god. Once you agree, you have to help him defeat an eighth-level alien creature that can hang up all human beings."

"Huh... at this moment, I just want to say..."

"No one dares to write like that?!"

Li Yu yelled in his heart, "Damn!", looking at the demon god in front of him, he couldn't help but look bitter.

Although the opponent has only a sliver of consciousness left, it is still very easy to destroy him with his power, Li Yu knows this very well.

It has no capital to reject the demon god at all.

"This matter is only good for you, not bad," Demon God said, "That alien creature will invade your world sooner or later."

"If you don't destroy it, you will successfully repel it, and it may make a comeback. At that time, your world will still be in danger."

"Under the overturned nest, there will be no eggs. You should understand such a simple truth?"

"Well...you're right."

Li Yu nodded. Although he didn't want to provoke that terrifying eighth-order alien creature, the words of the demon god had some truth.

If that eighth-order foreign creature is really an existence that the original world will face sooner or later, then Li Yu has no reason to let go of this opportunity to become stronger.

Destiny should be in your own hands.

Li Yu would not pin his hopes on the appearance of a person who could kill eighth-order alien creatures in the original world to save himself.

In contrast, Li Yu hopes that he has the power to protect himself.

"So, you agreed?"

The Demon God asked happily.

"Let's talk about it first, if the eighth-order alien creature hadn't invaded my world, I wouldn't be able to see it, so I wouldn't be able to..."

"Don't worry, with the character of that eighth-level alien creature, you will see it in your world soon."

The demon god interrupted Li Yu's words, and continued, "If you really can't see it, I won't force you to kill it."

"I just want to ask you one more question, are you really going to agree to my request?"

"I agree……"

Taking a deep breath, Li Yu continued to say these words.

"Ding! God-level mission! [Content: Complete the request of the demon god, failure penalty: ???]"

(Remarks: If the eighth-order alien creature did not invade in the end, it will not be considered a failure, and the task will automatically expire)
Suddenly, a system prompt sounded in Li Yu's mind.

The moment he finished reading the task, Li Yu instantly regretted agreeing to the Demon God.

There are punishments, tasks without rewards, inappropriate resistance to people...

"I feel the sincerity of your world will."

Suddenly, the demon god said something that made Li Yu feel a little unclear.

"Okay, I'll help you become a legend right now!"

As the demon god said, a powerful force suddenly emanated from his body.

The mighty power that shocked Li Yu instantly enveloped his body.

Immediately, a lot of information flooded into his mind.

This information is about a kind of magic, just like the feeling when the system helped him master magic, Li Yu found that he could easily master the magic knowledge flooding into his mind...

"It's not difficult to comprehend this magic. Basically, all demons who have the ability to come to the legendary island can comprehend it successfully."

Demon Shinto said, "You are also quite unique. Your aptitude for practicing magic is ridiculously weak, and you can't even comprehend this kind of magic."

Hearing this, Li Yu couldn't help feeling embarrassed.

"Now I have used my power to help you master it forcibly. Now that you activate this magic, you can start to temper your soul..."

As the devil's mythical sound fell, Li Yu directly urged the magic that he had just mastered that could help him break through the legendary level.

Suddenly, a purple magic circle flickered on him.

Although he has mastered many kinds of magic, the pattern of the magic circle appearing on his body at this moment makes Li Yu feel very strange.

He felt that this magic circle had nothing in common with other magic circles he was familiar with.

"Lost magic..."

The demon god muttered to himself, with a blurred look of recalling the past on his face.

In the era he lived in, there was a world of demons, legends were everywhere, and there were as many epics as dogs.

But that shocking battle with alien creatures brought the prosperity of magic to an end.

It can even be said that it is lucky that there are still demons alive in the demon world.

The great battle about the survival of all the demons in the world directly damaged the foundation of the demon as a creature.

After countless high-level demons fought to the death with alien creatures, they died.

After the war ended, the devastated world of demons didn't even have anything left to record the history of this war in detail.

The demons in today's world don't even know the races that sacrificed for the world in the demon world...

When the demon god recalled, Li Yu had already fully inspired the magic he had just mastered.

In an instant, a mysterious force from heaven and earth rushed into his mind.

"what!"

Severe pain suddenly fell on Li Yu's body.

All of a sudden, he felt his nerves being torn apart by something.

The unbearable pain caused Li Yudang to faint.

But within a short breath, he woke up again from the pain.

In a trance, Li Yu felt that his mind would be completely occupied by the influx of heaven and earth power, but his own consciousness would completely dissipate.

"The world of demons has long been dilapidated. Helping demons become legendary powers of heaven and earth has become very chaotic."

Demon Shinto said, "The magic you use can weaken the chaos of the power of heaven and earth, but if you don't have a powerful soul, you still can't withstand the baptism of the power of heaven and earth."

"I'm running out of strength, so I can't help you carry it directly. You have to hold on for a while."

Hearing this, Li Yu felt a little desperate for a moment.

A while...how long is a while?He now feels that every second is very difficult, even in just a few seconds, he can't hold on.

"Ka..."

He wanted to ask the Demon God for the specific time, but Li Yu didn't even have the energy to speak at the moment.

He devoted himself wholeheartedly to the process of resisting pain.

Consciousness is getting more and more confused...

Li Yu felt that he was about to die.

He was lying on the ground, his body trembling violently due to the pain.

In an instant, memories in his painful consciousness were like a movie playing, and a large number of images quickly emerged.

At Liu's house, Liu Ling was waiting for him.

The girl looked sad, and endured the days and nights of countless startling creatures from other worlds alone.

Can't fall here...

Suddenly, Li Yu's consciousness became clearer.

There is still a promise that has not been fulfilled, and Li Yu doesn't want to let himself just fall here like this.

He wanted to keep the girl safe.

This is his promise to her.

"what!"

Li Yu roared violently, his nails pressed into the flesh, and his teeth rattled.

He tried his best to hold on, not letting his consciousness completely dissipate.

Time goes by slowly...

Just when Li Yu's body was already numb from the pain and his soul was about to collapse completely, the demon god finally made a move.

"Very good, you have survived until now, the rest of the tempering, my remaining strength can just help you carry it through."

The demon god said something in relief.

Immediately, his entire body turned into a ray of light and enveloped Li Yu.

Suddenly, a cool feeling, like a life-saving magic medicine, quickly relieved Li Yu's pain.

At this moment, Li Yu just had the energy to perceive the changes in himself at this moment.

First of all, the most obvious thing is that the thinking is more flexible.

Li Yu found that he could quickly think of all the secrets of magic that he had mastered.

And his comprehension of magic seems to have risen to an extreme height.

If these mastered magics are used again, the power will be several times that of the past!
In less than a cup of tea, Li Yu's painful feeling has completely disappeared.

Instead, a powerful force stayed in his body.

This power is not magic essence, not aura, but soul!

The powerful power of the soul can cause a qualitative change in the power of the magic it casts!

So far, Li Yu has successfully broken through to the legendary level!

At this moment, there is one more poor legendary demon in the demon world!
"congratulations."

The figure of the demon god came into Li Yu's eyes again.

Visible to the naked eye, its body has become illusory, as if it will disappear at any time.

At this moment, the majestic face of the Demon God was full of haggardness, and Li Yu knew that his remaining sliver of consciousness would also disappear.

The strongest man in this world has ushered in his twilight...

"The world you are in has not been injured by alien creatures, which is enough to support your breakthrough to the god level."

Demon Shinto said, "Don't forget what you promised..."

Before the words were finished, the figure of the demon god completely dissipated.

The whole body turned for a while, and when he saw the surrounding scene clearly again, Li Yu found that he had already withdrawn from the space where he stayed just now.

Lush trees surrounded him, and Li Yu found himself in the forest on the island at the moment.

After looking around for a while, Li Yu didn't see the seven epic level demons who came with him.

Immediately sensing the devil's contract, Li Yu found that the contract with the seven demons was still there, which also proved that they were still alive.

Presumably they are working hard to comprehend the magic on the stone tablet that helps break through the legendary level...

Aside from accepting a punishing system task, Li Yu's trip was not insignificant.

It has become a true legendary demon.

Corresponding to the realm of monks, that is, the fifth realm!

At this time, he already has the ability to fight against the monks of the fifth level, and has the capital to fight against the Liu family!

"Liu Ling, wait for me!"

With a shout in his heart, Li Yu then left the legendary island.

There are still nine days before being forcibly teleported back to the original world by the system.

Li Yu planned to use this time to arrange everything in the demon world.

After leaving the Sea of ​​Legends, Li Yu returned to the Little Demon Village.

The news that he became a legendary demon spread like wildfire in an instant, and in an instant, the little devil village became one of the most powerful forces in the demon world.

Suddenly, a large number of demons wanted to enter the Little Demon Village one after another, becoming a member of this force surrounded by legendary demons.

"Master, congratulations."

Beside Li Yu, all the senior officials of Little Demon Village said in unison.

Nodding his head, Li Yu then told all the information about the legendary island, except the information about the demon god, to the high-ranking demons in the Little Demon Village who were epic demons.

At this moment, the Sea of ​​Legends is gone without the sea monster making waves, and the risk has been greatly reduced.

Li Yu still encourages the demons in the forces who want to break through the legendary level to go to the legendary island to accept the test.

Of course, apart from sea monsters, Li Yu also informed the demons about the risks in the test.

Also let them do what they can.

After arranging these things, Li Yu planned to return to the original world.

And on the day he was about to leave, five legendary demons in the demon world except him suddenly came to the little demon village.

They came here not to start a war, but to explain an unwritten rule to Li Yu.

That is, legendary level demons can no longer help their forces attack other demonic forces.

One is to reach the legendary level, and there is no need for magic stones.

Secondly, for legendary level demons, dealing with demons lower than their own level is simply a dimensionality reduction blow.

In order to avoid the situation where legendary level demons rampantly kill demons, there is such a rule.

Of course, it's not that legendary demons can't attack other demons.

If other forces come to the door, or if there are demons who take the initiative to provoke, they can also do it.

In fact, to put it bluntly, it means to do it if you want to, but you have to restrain yourself and don't cause too many outrageous casualties.

After all, a legendary demon is already the maker of the rules and has the final right to interpret the rules. As long as they are not too excessive, they will basically not be condemned.

Moreover, it's okay to be reprimanded. Demons below the legendary level have nothing to do except reprimand them.

Because they have nothing to do with the legendary level...

He readily agreed with several legendary demons suggesting that he abide by the treaty, and then Li Yu sent them away from the little devil village.

It will return to the original world later, and it is hard to say whether it will return in the future.

How can I have the time to attack other forces...

Taking a nostalgic glance at the thriving Little Demon Village again, Li Yu was filled with reluctance.

To be honest, the sense of belonging that the original world gave him was not even as strong as here.

People's hearts are complicated, but the demons in the demon world are somewhat simple.

They only have a hundred or eighty eyes on fighting, but they are very sincere in other aspects.

Be true to your lord, and be true to your companions.

Every force, as long as the lord does not implement tyranny, it will be a happy scene...

"Goodbye, Little Demon Village."

After taking a deep breath of the fragrance of the field soil in the power, Li Yu then took the initiative to apply to the system to return to the original world.

In an instant, the fainting sensation reappeared, and Li Yu immediately lost consciousness...

……

"Ding! It is detected that the host is leaving the demon world!"

"Ding! The system is paying the final payment to the demon world!"

"Ding! Demon World replied 'Thank you for your patronage'!"

(Remarks: Li Yu, a traveler from another world, is allowed to take away the obtained devil contract!)

"Ding! It is detected that the host has returned to the original world, and the system is adapting..."

After Li Yu regained consciousness, a system prompt suddenly sounded in his mind.

"Ding! The doomsday system has awakened again!"

Li Yu: "Welcome to the system!"

System: "^[-]^"
