The Strongest Upgrade System

"boom!"

The dark arrogance on his body moved, and the dark power in the sky was crushed, and the three forces rushed directly into the body of Niukeng City Lord.

"boom!"

"boom!"

Niukeng City Lord is not an opponent at all, and his body is directly blown open.

At this moment, Long Fei rushed to o

Seeing Niukeng City Lord fall, he shouted, "Don't..."

"experience!"

"Level, my experience, my level..."

Long Fei went crazy

To him, City Lord Niukeng is first-level experience. He now needs 500 million experience to advance to first-level. Where do you want him to get this 500 million experience?

It's absolutely impossible

Long Fei had the urge to die when he saw the city lord of Niukeng being killed.

I used all my strength to rush into the deep pit and bombarded the city lord of Niukeng a few times, but...it was useless.

Niukeng City Lord is dead!

Dark Demon coldly glanced at Long Fei, and said coldly, "Who are you?"

Long Fei was so angry that he turned around and scolded: "Who the hell are you?"

"court death!"

The dark demon was furious, and the dark Devilish Qi on his body rushed towards Long Fei, with killing intent flashing in his eyes.

Long Fei is not a vegetarian either, he grabbed the Dragon Saber and slashed it down with one slash.

The thick aura on the Dragon Slayer surging up, swallowed the blood of the city lord of The Underworld on the ninth floor, and the Dragon Slayer enhanced the power of the dark dragon spirit by a lot.

With one knife cut, the Dark Dragon God roared o

"Roar!"

The sword qi raged, directly dividing the dark arrogance into two.

shocking o

The Dark Demon's expression was startled, "The Supreme artifact of the Southern Sky Region, Tu, Dragon, Knife!"

The voice stopped word by word, and his eyes became darker, staring at Long Fei's extremely strong murderous aura, "People from the Long family o"

"I didn't expect that I would meet someone from the Long family again"

"Last time……"

Thinking of the last time, that was tens of thousands of years ago, his body trembled, looking at Long Fei, and then at the dragon slaughtering knife, he suddenly laughed wildly, "Woo ha ha... Now I know o"

after laughter o

All the killing intent on his body disappeared, and the darkness surrounding him, Devilish Qi slowly quieted down.

The dark demon laughed in his heart and secretly said: "King Yama, I now know why you want me to kill him, and you are also afraid of the dragon family, right?"

"You are also afraid..."

"Dragon Crazy!"

"Hahaha...Interesting, interesting, very interesting, hahaha..."

His heart is laughing wildly

Long Fei looked at the dark demon and said, "What are you laughing at?"

The dark demon looked at Long Fei and asked, "You entered The Underworld to save your ancestors of the Long family, right?"

"Uh?"

Long Fei was taken aback

Dark Demon looked at Long Fei's surprised expression and said, "Isn't it?"

He didn't know that Long Fei was blasted into The Underworld by King of Hell. King of Hell wanted to use the power of devouring on the eighteenth floor of The Underworld to refine Long Fei and Tianling.

Once their True Qi is refined, they are a waste

but o

How could King of Hell think that there is a system in Long Fei's body?

As long as there are monsters to kill, his True Qi will never be exhausted. As for Tianling, it is a perverted existence. The eighteenth floor of The Underworld is heaven.

King of Hell miscalculated o

Long Fei said: "So what? What about no?"

Dark Demon smiled and said, "If yes, I can help you."

"If it's not..." Dark Demon's smile turned cold and ferocious, and he said coldly, "Then I will kill you."

The dark devil has killing intent on him

Long Fei has felt it from the very beginning, and he is very strong, very strong, and being able to kill Niukeng City Lord easily is enough to prove that he is very strong, but why didn't he kill himself when he saved Long Kuangtian?

Long Fei asked, "Why?"

The dark demon laughed and said, "Because I want to go out, I am afraid that only Long Kuangtian can do it in The Underworld!"

"wrong!"

"Long Kuangtian couldn't do it before, but!" The Dark Demon stared at the Dragon Saber in Long Fei's hand and smiled excitedly: "With the Dragon Saber, he can do it."

"Uh?"

Long Fei was secretly startled, "Long Kuangtian, is he the ancestor of the Long family? How many generations of the family master?"

Long Fei has read the family tree of the dragon

But for the Long family tens of thousands of years ago, he only knows the first generation of the dragon family, and there is no record on the family tree of the names of the hundreds of generations of the family.

The genealogy preserved by the Long family was recorded from the beginning of five hundred years. As for what happened to the Long family in the previous five hundred and ten thousand years?

no record

When he was reading the family tree, he wondered o

I thought it was lost, but I asked my grandfather to find out that the genealogy was recorded from the beginning of 501, and the previous ones were not recorded. As for the reason, he did not know.

No one in the Long family knows!

"Dragon Crazy?"

"This name is really familiar..." Long Fei murmured a few words in his heart, looking at the dark Devil Dao: "What floor is my ancestor on?"

Dark Demon smiled and said, "The eighteenth floor o"

"People like him are naturally imprisoned on the eighteenth floor."

"Otherwise, what do you think can hold him down?"

Dark Demon is crazy

He didn't even look at King of Hell, but when it came to Long Kuangtian, his eyes were full of respect, the kind of respect that came from the heart.

Long Fei froze in his heart, "How strong is this ancestor of the Long family?"

"Does he know more secrets of the Long family?"

"The Long family is really mysterious o"

I feel more and more that the Long family is too mysterious.

Dark Demon's Cultivation Base is infinitely close to the God of War Realm. What Realm did Long Kuangtian on the last floor arrive at?

War Great Emperor?

When did the Long family produce such a strong man? Why was it never recorded?

There are too many secrets in everything o

"call……"

Long Fei said, "Do you want to be with me?"

The dark demon laughed and said, "It seems that you really came to save Long Kuangtian. If that's the case, I'd like to join you."

"it is good!"

"However, I have a condition." Long Fei didn't want to suffer from liver pain, and he didn't want to lose first-level in vain. Level was too important to him.

Dark Devil Dao: "You said it!"

Long Fei said: "You can only fight, not kill, the city lord on the next floor. If you kill him, leave it to me."

Dark Demon said indifferently: "No problem, as long as I can see Long Kuangtian again, everything else will be fine!"

His expression is like a brainless fan

I'm so infatuated with Long Kuangtian

As for why he was so infatuated with it, Long Fei didn't know.

"Master, are you alright?"

"Shhhhh..."

A large wave of people fell in the deep pit, watching all the evil ghosts in the Niukeng die tragically, their expressions are secretly stunned.

The Dark Demon glanced at these people, then saw Long Fei, and secretly said, "He should be the person King of Hell wants me to kill, right?"

"Hahaha……"

"pity!"

"He doesn't know my relationship with the Long family at all."

For dark demons, Long Fei is also vigilant.

On the 10th floor of The Underworld, Long Fei didn't earn a single True Qi, and now it has dropped by 400 True Qi per second. He must replenish it quickly.

Long Fei raised his arms and said, "The next floor, Shiba The Underworld!"
