The Strongest Upgrade System

Almost died, Long Fei was very upset.

"Daddy's life?"

"Want to steal daddy's stuff?"

"Yes!" Long Fei said fiercely.

He can travel freely in the mountain. According to the system's description of the Shadow Step, he can travel in the mountain for five hours. As long as he doesn't go out, no one can find him.

Shadow Step is simply a heaven-defying escape Cultivation Technique.

Invincible state.

Unless someone can destroy the entire mountain range with one move, Long Fei will not die.

"Find it for me!"

"Look carefully, even if you dig three feet in the ground, you have to find him for me." The devil said in a deep voice, his senses were constantly expanding, and he searched again and again.

But!

Just can't find the breath of Long Fei.

Certainly cannot be found.

However.

He didn't know that Long Fei was in the mountain in front of him.

now.

Long Fei was drooling, his eyes glowing, he wanted to swallow the boss, "It's too tempting, 500 million experience is too tempting."

"Gudong!"

He is someone who can't move when he sees the boss, and Long Fei's mind is flying, "If you use it again... It's a pity that Itachi is cooling down, if you can use his Illusion Art to do it again, the epee has no edge. The power is enough to explode again."

"Not urgent!"

"Not urgent!"

"Those who do great things have to keep their temper."

"Daddy has time!"

At this time, the devils were all on alert. In this state, both their strength and defensive responses were extremely sharp. If they didn't succeed, Long Fei would probably die.

He is like a cheetah hiding in the dark, quietly observing its prey, waiting for the fatal blow!

"Your Highness."

"I have searched the valley again, and I have not let go of every corner, and I have not found..."

Before waiting for the little minion to finish speaking, the purple Devil Venerable drank immediately, "Look again, his Cultivation Base can't escape, it must still be in this valley."

The little minion didn't dare to say more, and immediately said, "Yes!"

Another devil came up and said, "Second, that kid is very weird, he must have escape Magic Treasures on him, I think we should withdraw, the task given to us by the Sect Leader has been fulfilled, guard the dragon sword and leave the seal place."

Purple Devil Venerable said solemnly, "Dage, the third he..."

The big devil said, "I'm also very sad about the death of the third child, but don't worry, I must avenge this revenge. You have heard what they said at the beginning. That kid is the representative of Xianwu Pavilion. Go back to Sect and check it out. Now that you know where Xianwu Pavilion is, we will destroy Xianwu Pavilion at that time."

Hearing this, Long Fei's heart tightened.

"It seems that none of them can go back, otherwise Xianwu Pavilion would be in danger."

"I don't know what happened to the pavilion master."

Long Fei's eyes were more murderous, and he said to himself, "Is their mission just to let the guardian dragon sword leave? It seems that there must be something strange under the seal under the guardian dragon sword."

"I don't know if I can burrow into the ground with this shadow step?"

"Try it!"

With a thought, Long Fei went straight to the depths of the ground.

What surprised him was that he could drill very deep without any restraint at all.

instead.

Long Fei took out the guarding dragon sword and said, "Dragon sword, take me under your seal, I want to see what Devil there is."

Guarding Long Jiandao "Understood!"

As soon as the guarding dragon sword moved and pointed out the direction, Long Feijianyingbu immediately followed.

Continue to dive deep into the ground.

After half an hour, the guarding dragon sword stopped and said, "Master, this is the place."

It's a huge open space.

It's like an underground cave.

Long Fei walked out of the mountain, and the system also sounded a prompt tone.

"Ding!"

"The system prompts that the shadow step duration is over."

As long as Long Fei leaves the three-body, the duration will end, but when Long Fei glanced at the cooldown time of Glancing Step, he became excited, "The cooling is over?"

"Hahaha……"

"I know, as long as the skill is released, the skill is in the process of cooling down. More than half an hour has passed, and the cooling will end naturally."

"It's awesome!"

Long Fei was a little excited and looked at the sky-high gate in front of him.

To be precise, it should be facing the ground.

The door is upside down.

It is thousands of feet high and extends directly to the depths of the ground.

Four characters are engraved on the heavy stone gate. These four characters are not ancient characters, nor are they rune characters, they are ordinary four characters.

"Death to trespassers!"

Long Fei looked at Long Jiandao who was suspended beside him, "Didn't you say that you can rush out if you leave the Devil in the seal?"

Guarding Long Jiandao "It's true, but I haven't left the valley yet. Only when I leave this sealed valley can I truly leave."

"and!"

"It's been so long, it's hard to say whether these suppressed Devils are still alive."

too long.

For trillions of years, let alone humans, even gods would die of old age in it!

No matter what kind of race, life is not infinite.

Outland Devil is the same.

Trillions of years are really too long.

Long Fei looked at the huge inverted door and said, "Can you open the door?"

The guardian dragon sword froze slightly and said, "Master, do you want to open it?"

"In case the Devil inside is still alive, then..."

Guarding the Dragon Sword is also not guaranteed.

but.

He has seen images of Devils from Outland running rampant in the Hongmeng Realm. It can be said that half of the Hongmeng Realm has been destroyed by those Devils, and the destruction is almost in a state of cracking.

They have only one purpose, to destroy!

Long Fei looked at the door and said, "I want to go in and have a look."

Guarding Long Jiandao "Master, this is too dangerous. If an accident happens, then I'm afraid..."

Long Fei looked at the door of The Underworld, giving him a feeling that once he opened the door, blood would pour out, but he really wanted to open it.

Long Fei said, "I still want to go in."

Guarding Long Jiandao "Okay, since the master wants to go in, then I will open it."

"I am the key to open this door."

"There are also eight other places in the Hongmeng world, and the other eight guarding dragon swords are also keys."

talking room.

The guarding dragon sword flew and flew directly into the abyss.

After half a minute.

I heard a loud 'click', "ka, ka, ka..."

The door of The Underworld slowly opened.

a long time.

With a "bang" sound, the two stone gates were all opened.

Also at the same time... the whole mountain started shaking, shaking, rocks rolling, the Demonic Beasts in the mountains, whether you were a huge super Demonic Beasts or a low-level Demonic Beasts, they were all the same, shivering on the ground, constantly Frightened low roars, thousands of birds flying, crows chirping, all within a radius of hundreds of thousands of kilometers, just like the end of the world...
