The Strongest Upgrade System

"kill!"

The body dashed forward, the dragon-slaying knife in his hand fell, and he slashed down at a giant dragon.

"boom!"

The fire was scattered, and this knife only cut off a few dragon scales of the dragon.

Got stronger again!

I want to compare the strength of the dragon in front, the defense of this dragon has been doubled.

"Boss!"

Xiaobai shouted, "It's here!"

The giant dragon let out a roar, and its extremely ferocious body was tossing in the air. At the moment when Long Fei pulled back with a knife, the giant dragon was possessed and charged down.

"Roar……"

roar o

The huge faucet is pressed down, like the sky is falling.

Long Fei is not afraid

Looking at the faucet that rushed down, Long Fei suddenly jumped at the last minute, stood on top of the faucet, and said, "No matter how strong you are, you have to lie down for me!!"

"boom!"

The dragon-slaying knife in his hand burst out with the real dragon-slaying power, and it stabbed fiercely, piercing the skull, and the blood shot out. The dragon's body kept rolling, roaring, and screaming in pain.

Long Fei doesn't care

A punch hit the hilt of the dragon-slaying knife, "Get down on my stomach!!"

"Crack!"

The dragon-slaying knife completely pierced into the dragon's head, the central nervous system ruptured, the dragon's body slowly shrank, and the huge body fell to the ground.

Blood volume bottomed out

"Ding!"

"Congratulations to player Long Fei for killing a giant dragon for gaining 2.1 billion experience points, 2 million immortal power points, and 1 energy point o"

"Congratulations to player Long Fei for getting the dragon bloodline. Is it fusion?"

"Swallow!"

Devour the blood vessels, and directly devour the dragon's blood vessels.

"Ding!"

"Congratulations to player Long Fei for upgrading to the second rank of Fei Xian!"

"continue!"

Long Fei walked forward again, there was another explosion in the void, and another more powerful dragon flew out of the void.

...

far away

The Demon Ancestor of the Western Regions asked slightly: "Brother Gu, don't we take the lead?"

Gu Tongtian closed his eyes slightly, closed his eyes, and said lightly: "This is the dragon domain, the dragon's world, Long Fei is the son of prophecy, and only he can reach the highest point step by step."

"Only in this way can the Dragon Domain be fully activated"

"don't worry o"

"With Long Fei opening the way, we can save a lot of things. As long as he has not reached the Dragon Palace, we don't have to worry about it." Gu Tongtian devised a strategy.

He seems to know everything in the Dragon Domain very clearly.

The Demon Ancestor of the Western Regions is even more puzzled.

Gu Tongtian is only four hundred years old, and the dragon domain has disappeared for more than six million years. He has never seen the dragon domain at all, unless there are strong people in the outer domain who know everything in the dragon domain and tell him all about it.

if it is like this……

The Demon Ancestor of the Western Regions froze in his heart, and secretly said: "The Dragon Region may not only be the secret of longevity, but there should be something more powerful in it."

"This kind of powerful thing is what the outer domain powerhouses behind Gu Tongtian need!"

"What exactly is it?"

"Dragon race is a foreign race, why did they come here? Did they escape here? With a super spiritual treasure?"

He is now more and more sure that the Dragon Domain Secret Treasure is definitely not a secret of longevity, it must be another powerful thing that they can't imagine.

what is it?

The Demon Ancestor of the Western Regions looked at the magnificent Dragon Palace in the distance, and clenched his fists secretly in his sleeves.

...

"kill!"

"Boom!"

"Ding!"

It's another giant dragon flying and beheading o

this time o

Long Fei also suffered a lot of injuries and spit out a mouthful of blood, "It's getting stronger and stronger, this Dragon Domain is much stronger than I thought."

A full month has passed o

Long Fei struggled to take less than a thousand steps, killing every ten steps.

Extremely difficult!

In this distance without a thousand steps, Long Fei's body, strength and speed are constantly getting stronger, every time it is like a breakthrough of the limit.

"Come again!"

Long Fei roared and rushed up.

Long Shanfeng and Long Zhanhai looked at Long Fei, and their hearts were very uncomfortable.

Everything in the Long family is on Long Fei, they can't do anything o

Linglong, they are the same

Can only watch Long Fei suffer, they can't do anything, this feeling is very uncomfortable o

The second month is over!

The third month is over!

...

time flies o

There are ten thousand steps to reach the Dragon Palace. From the moment Long Fei stepped on it, Long Fei has not stopped killing. In half a year, he beheaded hundreds of giant dragons.

One is stronger than the other

One head is more cruel than the other

Every time Long Fei is desperate o

"Ding!"

"Congratulations to player Long Fei for upgrading to the sixth rank of Fei Xian!"

Half a year, promotion fifth-levelo

extremely difficult fifth-levelo

Now Dragon Soaring to first-level requires tens of billions of experience, which is too difficult!

Long Fei looked up, getting closer and closer to the Dragon Palace, gritted his teeth, and said solemnly: "Continue!!"

...

"Cough cough cough..."

"Cough cough cough..."

Gu Tongtian coughed continuously, coughing up a pool of blood, his face was pale, and he looked like he was running out of oil.

His life span has reached the limit o

Everyone looked at Gu Tongtian and became a little worried.

"Sir, do you want to urge Long Fei to speed up?"

"Catch a few people around Long Fei and let him hurry up"

Gu Tongtian is the only one who can deal with Long Fei. They are not opponents at all. If Gu Tongtian dies, the secret treasure of Longyu will have nothing to do with them.

So they are very worried about Gu Tongtian's physical condition o

Gu Tongtian raised his head and took a small Medicine Pill, and said slightly: "Don't worry, I can't die now."

Medicine Pill entered the body, his complexion quickly returned to ruddy, and he was full of energy, not like a person who had exhausted his lifespan.

Gu Tongtian looked at Long Fei in the distance and said, "I've been waiting!"

"Long Fei, don't let me down o"

Gu Tongtian's Shouyuan has arrived o

The reason why he didn't die is because of the Medicine Pillo he was taking

Possess the ability to survive

This is also the Medicine Pill given to him by the strong man, the purpose is to give him more time to help him do that thing, that thing that can be heaven-defying o

Even the upper god world trembles!

"boom!"

"boom!"

Long Fei was knocked out, his body was phantom, he rushed up again, and the Pangu axe in his hand slashed against a giant dragon, "Guillotine!"

"boom!"

A dragon head flew down, and dragon blood was sprinkled all over Long Fei's body. The hot, scalding dragon blood made Long Fei feel even more excited.

"Next!"

keep moving forward

Eleventh month!

Long Fei stepped on the last step o

"Buzz!"

With a loud noise, a huge dragon shadow rushed out of the void.

nothing else

But Yuanlong! !

At the top of the ten thousand steps, boss!

Yuan Long smiled slightly: "Long family boy, you are finally here, I have been waiting for you here for a long time, woohaha..."

"Give me everything you have o"

"Everything you should be prepared for me!"
