The Strongest Upgrade System

Long Fei's tone was domineering and could not be disobeyed.

As if his words were inevitable and absolute.

Mu Nanyou's eyes flickered instantly.

She trusts Long Fei so much that she has no doubts at all.

No matter what Long Fei said, she was convinced.

So now that Long Fei said this, it directly affects her fantasy, thinking that the day when she is invincible is coming.

At this time, the black dragon recovered and came to Long Fei with a look of excitement.

"Old Ancestor, let's enter the city, I feel that my whole body is full of power now." Heilong's eyes were wild.

All the previous fears were gone.

Instead, there is a sense of rush to try.

"it is good."

Long Fei nodded.

Although it is still a while before the system is opened, the transformation of the black dragon has given Long Fei a little confidence.

The next moment, the two figures directly boarded the void and entered the city of Heavenly Devil.

As soon as they entered, their expressions changed slightly. Although they have improved a lot now than before, the scene they saw in front of them still shocked them.

The city is not as ruined as they thought, nor has it been abandoned, and even every building is intact.

Not only that, there are countless ghosts in this Heavenly Devil city, and they don't look like they are abandoned at all.

"How could this be?" Heilong's expression became solemn.

I feel like what I said just now is a little swell.

I feel like I'm too floating.

Coming in here, he felt that he had spoken a little too early.

The atmosphere here is full of strangeness.

Especially these ghosts, all of them have hawk-like eyes falling on them.

It felt like they were the real thing on the dinner plate, and the ghosts were salivating.

But in nothingness, Long Fei was completely indifferent.

Although there is something in the atmosphere here, for Long Fei, the gap in level cannot be made up.

Just these existences can't touch Long Fei's heart at all.

Not even the slightest feeling.

However, this power still has some influence on Heilong and Mu Nanyou. If nothing else, it can be seen just by looking at the expressions of the two at this time.

Subconsciously, Long Fei calculated the time.

There are the last five minutes.

As long as five minutes, the system can be upgraded to complete.

Nothing will be a problem then.

Long Fei naturally didn't believe that there would be a change in these five minutes.

But at this moment, a mutation suddenly occurred.

Mu Nanyou seemed to be lost, and walked forward step by step.

"Girl!" Long Fei instinctively felt surprised and asked.

However, Mu Nanyou didn't respond, as if he didn't hear Long Fei's voice.

Like a madman, walk straight in.

"Grandma?" Heilong also stopped.

But even if Long Fei couldn't call him, his words were in vain.

Also at this time, the Heavenly Devil shadows swayed, extremely ferocious, one by one with their teeth and claws, and even in the void, a low-pitched demonic howl appeared.

"Welcome to Heavenly Devil City!"

Suddenly, a voice appeared again.

It was the voice of the demon face before.

Long Fei was unmoved, whether this Heavenly Devil King, or the Lord of the Ancient Demon City, did not have the slightest deterrent effect on him.

It's just that Mu Nanyou's changes now surprise Long Fei.

He didn't make a sound, and he didn't even scream, as if he was stunned.

This is not a good sign. Especially the purpose of this Heavenly Devil king is very obvious, that is, he came to Mu Nanyou, and when Mu Nanyou came in here, he seemed to be in a state of desolation, like a ghost, it was too abnormal. "Jie Jie, pure true demon blood is really coveted. Back then, when Lord Chaos laid out the demon land, he left his inheritance, and destroyed that lineage. I never thought that blood would still be circulating in the world. Hahaha, as long as I got this The devil's body, when the time comes

I am the ruler of the Ten Demon Cities. "The voice appeared again, and he laughed wildly, as if everything was in his hands now, and Mu Nanyou was the thing in his bag, the lamb under the knife.

"Dog thing, what are you doing?"

As soon as Heavenly Devil's voice fell, the black dragon roared. "What am I going to do? Jie Jie, of course, I have taken her bloodline. Of course, there is also you, an upgraded demon dragon, the power of bloodline has even surpassed that of the dragon demon. When I take his bloodline, I will refine you again. , I will be invincible in the world."

Heavenly Devil laughed wildly.

I have to say, this gesture is really arrogant.

Even if he hasn't shown his face yet, his voice does not hide the rage and the arrogance that controls everything.

But these words, to Long Fei's ears, are no different from a fool.

Invincible?

Is this what it says?

Even Long Batian may not dare to say such words, how dare he speak the world with such a thing?

If so, it must be the bottom of the well.

A panic appeared on the black dragon's face.

Although he has transformed now, Cultivation Base has reached the Wanfa state, but it is still not enough to watch.

The existence in the depths of Heavenly Devil City would still bring him boundless pressure.

So hearing this kind of words now, my mind is instantly lost and I can't calm down.

"Ancestor..." Heilong said directly, asking for help from Long Fei.

Long Fei ignored it and ignored it.

Too watery!

Heilong's character, compared with his former brother, is not a star and a half.

The Eight Vajra, the Thirteen Great Emperors, and even their own sons are better than this.

All of them are stern, and they will not say a word of cowardice in anything.

This product is good, no matter how the strength is improved, there are only three words in case of trouble, the ancestors.

Seeing Long Fei not responding, Hei Long's eyes were also instantly lost.

He could even feel the emotion brought by Long Fei's silence.

That is disappointment.

"No, the ancestors have done so much for me, how can I let the ancestors down. No, I want to rise." Heilong growled inwardly.

Soon, anger overwhelmed fear.

In an instant, the black dragon transformed directly, and the thousand-zhang giant dragon soared into the air.

"Damn it, Heavenly Devil, right, daddy doesn't care what kind of ancient demon you are, or what kind of master of the devil ruins you are. Now, let my grandmother go, or daddy will overturn your Heavenly Devil city."

Heilong was furious, and after weighing the pros and cons, he finally decided to break out.

"Huh? Dare to resist? It's an honor for me to see your bloodline? You dare to resist? Damn it!"

Heavenly Devil's voice appeared, with shock and killing intent.

From his point of view, his own aura is here, and it's not too easy to suppress the black dragon.

Unexpectedly, the black dragon is not afraid of his threat now.

Even Long Fei was shocked.

To be honest, the old ancestor that Heilong said before made Long Fei really unhappy.

Typical sand monk character.

There is only one big brother when encountering things.

If a daddy has to do everything by himself, what would he train you to do?

But it is also because of this that the black dragon's violent rise now makes Long Fei look at him with admiration. "Don't talk nonsense, let my grandmother go." Heilong gritted his teeth and said, obviously ready to go all out and fight the last one.
