The Strongest Upgrade System

"Ding, congratulations to the player for upgrading, the current level, the fourth floor of ancient power, the experience 600000/20000000000 points."

Feeling the power that filled his body, Long Fei's pupils shot out a bright light again.

Upgrading means that all energy is full.

"What's so special, only 20 billion experience can break through?"

Long Fei was speechless. The first-level was only over 10 billion, and this time it went straight to 20 billion. What about first-level?

What about upgrading to the 9th floor of the ancient power belt?

For the first time, Long Fei felt that the upgrade was so difficult.

"Looks like it's time to move on to a more advanced map. Heavenly Emperor qualification battle, I should have something to look forward to." Long Fei thought to himself, looking at the empty Yantian Ranch in front of him, his heart was empty.

Killing is also a form of redemption.

What's more, it was a system task now, and Long Fei didn't feel any pressure in his heart.

"There are only three days to collapse the Yantian secret realm."

"Now that Yantian Ranch has been emptied, the next step is the Netherworld Yellow Springs and the Temple of the Gods."

Long Fei thought in his heart, without hesitation, his eyes locked in another direction.

Ghostly Yellow Springs.

What Long Fei didn't know was that after his figure disappeared, he was on the edge of Yantian Ranch.

A disciple of the Yantian Clan trembled while holding a bronze mirror in his hand, his face turning pale.

"It's terrifying, is he a human or a devil?"

"The entire Yantian Ranch is gone like this? How do I feel that we are eating with a tiger."

"I suddenly have a bad hunch, will this time the secret realm hunt be too simple as we thought."

Several disciples of the Yantian Clan said in a low voice.

Long Fei made such a big movement, they had already sensed it through the bronze mirror.

It was also because of this reason that he could sense the breath of Long Fei before.

But they are the leaders, they control the bronze mirror and can know the first-hand resources.

Originally, they were in high spirits and high-spirited, wishing that whoever found Long Fei first would get a great fortune.

But now, there is only deep fear.

Long Fei was so violent that he swept the entire Yantian Ranch by himself.

This kind of thing, even Bai Hao can't do it.

No, not at all.

"We have to inform the young master immediately that the plan has changed this time."

"Yes, the young master still has imperial soldiers in his hands, so he should be able to kill him."

"Walk!"

Several people did not dare to hesitate and left in a hurry.

At this time, Long Fei had already straddled a million miles away.

If the distance of a million miles is outside, it may take a little time.

But in this secret realm of Yantian, for Long Fei, it's a no-brainer.

Because he has the power of heaven.

And he knew the entire Yantian secret realm well before entering the door.

Therefore, directly use the third-level Tianyan Technique to draw the portal of teleportation directly in the void, lock the Nether Yellow Springs, and you can reach it in an instant.

Bang!

Long Fei's figure fell heavily from the void.

"Fuck, it's too unreliable. Isn't it a good idea to lock the target and teleport?"

"What's the matter with such a natural fall from the sky?"

Long Fei was extremely unhappy in his heart.

However, in the face of the task, all the negative influences are paper tigers, and they are suppressed with a snap of their fingers.

Instead, Long Fei looked towards this space.

It is fundamentally different from what Long Fei imagined.

At first, when he knew about the ghostly Yellow Springs, he thought it was the Great Emperor Yantian who wanted to create a Samsara world.

But here, it's more like an ancient tomb.

There was no light in the entire space.

"Yao Shi Xing Huo, come out." Long Fei calmed down, took out a cluster of flames, and illuminated the entire space.

But at the moment when the light of the fire shone, Long Fei felt that his whole person was not well.

Nothing!

The emptiness made Long Fei's heart beat a little.

"Why is this place so similar to the Emperor Changsheng's tomb? Could it be that this is the tomb of the Great Emperor Yantian?" Long Fei guessed in his heart and walked forward step by step.

"Roar!"

But just two steps away, a roar appeared.

Immediately afterwards, the ground where Long Fei was standing suddenly began to turmoil, fluctuating.

It seems that what he is stepping on now is simply a behemoth.

Boom!

Boom!

The earth rolled, and countless rolling stones fell from all directions, and the rocks pierced through the air.

"Big killer, sure!"

Long Fei activated the big killer and turned it into a square shield to protect himself.

"The power of Tianyan, I finally waited for the second power of Tianyan, and the Yantian Great Emperor didn't lie to me."

In the endless darkness, a sound like thunder appeared.

Long Fei's heart tightened and he looked forward.

Seeing this, Long Fei froze in place.

The light of the boss that can't be covered up by the air of darkness.

The glittering golden light directly made Long Fei's heart surge.

boss!

And it's a super big boss!

"Boy, remove your defense, obediently return the power of Tianyan to me, and I will give you a piece of honor and make you the creator of the world."

The boss opened his mouth lightly, and on the big mouth of the blood basin, one after another harassment kept falling.

Falling down, it directly turned into a dark river.

"This f*ck is too scary." Long Fei looked at the behemoth in front of him, unable to make a sound.

This is a boss that is not fake, but it is impossible to look directly at it.

The size of the body is unmatched even by the Azure Dragon of the year.

to be exact.

The entire space of the Nether Yellow Springs is transformed by the body of this boss.

"Quick, boy, if I'm not wrong, you should be the descendant of Yantian. I can feel that the power of Tianyan is in you, give it to me, and I will lead you to break through the ancient world and become the The creator of the world."

The boss keeps talking and keeps tempting.

If it were someone else, I'm afraid it would have already fallen.

But Long Fei is different. Will Long Fei believe the words of a boss?

nonexistent.

There is only one attitude towards bosses, and that is to kill them.

"If you want the power of Tianyan, come on, come and get it if you have the ability."

Long Fei said, and began to test.

The level of this boss is too high, and it is completely impossible to see through the attributes. On the huge head, there are only three characters of Tianyan beast.

The rest are all question marks.

Attributes, HP, Damage.

It's all question marks.

It is completely beyond the range of the system's estimation.

"Boy, are you angering me? You dare to do things that Yantian didn't dare to do back then." Tian Yanbeast began to get angry.

In a fit of anger, the entire space was unstable.

Long Fei only felt an unspeakable coercion pressed down.

"Kneel down for me!"

Tianyan Beast spoke again.

Long Fei only felt a sweetness in his throat, and his internal organs were scrambling under the sound.

Long Fei suddenly raised his head, and a burst of anger erupted.

"Kneel down for you?"

"You are such a boss, let me kneel down for you?"

"Look, you are so awesome. As a boss, you have no self-awareness. If you don't blow up today, the daddy won't be called Long Fei."

Long Fei was furious, and when he raised his head, the killer weapon in his hand turned into a massive butcher knife that was several thousand meters tall.

"Isn't your body amazing? Daddy will cut you into pieces today."

Long Fei said, and blasted out with a knife.
