God-level upgrade system

Soon Wei Yi and the six came to the front of the palace on the last floor of the core underground palace.

Standing outside the palace gate, several people couldn't help but took a deep breath.

Although they were well prepared psychologically, when this critical moment came, they still couldn't help feeling a little nervous.

Anyone can guess that the big boss guarding the last floor of the palace is definitely not easy to deal with.

At least it will be a Martial Emperor level existence!

Although each of them has quite good cultivation and strength, and their past records are also impressive, but the superpower at the level of the Martial Emperor is still a colossus to them.

Even though Wei Yi once beheaded an ancient corpse demon comparable to a Martial Emperor-level powerhouse, that ancient corpse demon had only just awakened. In fact, his real combat power was far from returning to its peak state, and he was still fighting with Zhang Zhimin and the dog warrior The three joined hands together.

And this time, the opponent they are going to face will not only not be in a weak state, but it is likely to be more dangerous and terrifying than ordinary Martial Emperor-level powerhouses.

Of course, that doesn't mean they have no chance at all.

After all, each of them has greatly improved their cultivation and strength, and this time they are six people teaming up. As long as they play well and cooperate properly, the combined combat power is not much worse than that of the Martial Emperor level powerhouse.

"Whether it's life or death depends on what happened."

"Let's go in."

As soon as the words fell, a flash of determination flashed in the eyes of the six people at the same time, and then they pushed open the palace door together and walked in.

It was Wei Yi and Li Beiming who were leading the way.

Mrs. Huo and Huo Sangui followed closely behind.

Ximen Qing and Zhang Zhimin followed behind.

The six of them quickly walked into the last palace together.

The light and shadow flickered, and the scene in front of everyone's eyes changed dramatically in an instant.

They took this step, as if they had crossed the boundary of space, and they came from one space to another all at once.

In a blink of an eye, the six of them were no longer in the original palace.

Instead, he was already standing in an extremely dark and mysterious world.

As far as the eye can see, there are towering and terrifying volcanoes everywhere, billowing black smoke fills the entire sky and clouds, and the ground under the feet is covered by rivers of magma.

With the strong smell of gunpowder smoke and the extremely suppressed aura, all six of them felt a heavy pressure standing here.

There is still a faint trace of extremely cold death breath circulating endlessly.

"This is?"

"It seems to be the hell world in the rumors."

Everyone looked around and couldn't help but secretly startled.

"It seems that this is the last floor of the real underground palace."

Wei Yi muttered to himself, "I just don't know what kind of monster that big boss guarding the gate is..."

In such a dangerous space right now, Wei Yi no longer expects the big boss they encountered to be a normal person.

After all, normal people would not stay in such an extremely oppressive world.

And at this moment, without warning, the ground under everyone's feet suddenly trembled violently.

boom boom boom-

As if the sky was falling apart, not only the whole earth trembled, but also huge black gullies and cracks spread out rapidly.

Billowing magma spewed out from below the surface, like red fountains.

These red magmas are terribly high temperature. If they are contaminated by people, they will definitely cause serious injuries, and even lose half of their lives if they are not dead.

Everyone couldn't help but change their faces when they saw this. They were all normal people, with mortal bodies, how could they withstand the spray attack of these red magma, and they dodged again and again in desperation.

But at this time, the surrounding volcanoes also came to join in the fun.

As the ground trembled violently, those volcanoes erupted uncontrollably, and the huge sky was filled with falling flames, and the raging sea of ​​flames directly permeated the entire space.

The expressions on everyone's faces became even more ugly. Up to now, they couldn't bear it even before their opponent showed up.

If this world collapses, they will undoubtedly die along with them. They don't have the ability to travel through space.

Whoosh whoosh—

The figures of the people flickered endlessly, constantly avoiding the two sides of the magma and flames.

Billowing gunpowder smoke swept across, and everyone's vision gradually became blurred.

"Everyone, be careful underground."

After all, Wei Yi has been practicing fire-attribute skills, and he is more resistant to such a flaming environment. He was keenly aware of the abnormality under the ground, and immediately shouted anxiously.

At the same time as the voice sounded, his whole body instantly soared into the air.

Seeing this, the others followed suit one after another, and quickly rushed into the air.

Crack, click——

The earthquake cracked, and a huge gully with a width of tens of meters appeared under everyone's feet.

Immediately afterwards, a terrifying black figure slowly walked out from the underground magma, carrying terrifying high temperature and monstrous devilish energy.

As it walked out slowly, the space that had been trembling and roaring crazily finally regained its stability.

Everyone looked closely and found that this huge black shadow was a terrifying monster with three heads.

It is tens of feet long, and its whole body is covered with red and black scales. It has nothing to do with the billowing magma staining its body.

Straits of black demonic energy visible to the naked eye wrapped around its body, like poisonous snakes. The appearance alone made people feel frightened.

"This is... the three-headed hell dog?"

Seeing the true face of this terrifying monster, both Mrs. Huo and Li Beiming couldn't help exclaiming in unison.

Immediately, the expressions of the others also changed involuntarily.

The hell three-headed dog is a powerful monster in ancient times. It is said that it was born of the demon king and the snake girl. It is responsible for guarding the gate of the hell world and has a very good reputation.

The hell three-headed dog has the heads of three vicious dogs, each of which has a big mouth with ferocious fangs, and also has a poisonous snake's tail, and has the mysterious ability to control flames.

It was born by bathing in the flames of magma, absorbing magic energy to grow up, and its body is invulnerable. It can be regarded as one of the most terrifying high-level monsters. It is notorious and frightening.

No one expected that the gatekeeper boss on the last floor of the core underground palace would be such a terrifying monster.

Right now, the hell three-headed dog is not only a seventh-order monster, but also the top seventh-order monster. According to everyone's estimation, its strength may be comparable to those of the top masters of Tai'a Mountain.

For a moment, the six of them couldn't help but look bitter.

The six of them can work together to deal with ordinary seventh-order monsters, but the chances of winning against a terrifying monster like the hell three-headed dog are really not much.

"How to do?"

Everyone couldn't help showing panic.

"What else can we do? If we don't kill it, we can't even get out of this space, let alone leave the ancient tomb space safely. Are you willing to stay here forever?"

Wei Yi asked back.

At this time, the hell three-headed dog also came towards them.
