Strongest Instant Upgrade System

It was the most terrifying and mysterious forbidden land in the inner world.    

The most mysterious thing about it was that it didn't have a fixed location, it was moving.    

But every time it appeared, it would set off a beast tide and a bloody funeral.    

If it appeared in the inner parts of Butterfly Valley of Hundred Flowers, it would be a great gift to the devils.    

A body of flesh and blood like the King Beast, even if it possessed some kind of innate divine ability, it was no different from meat on a chopping block in front of the Evil Devils.    

Under the corrosion of the Demonic Qi, it would quickly transform into a devil beast, turning into a bloodthirsty devil who hated all humans and only knew how to kill without reason.    

"Now that things have come to this, I can only fight with my back against the water." Fan Yixiao looked at all the disciples present and said loudly.    

"Fight! Fight! Fight!" The disciples were all excited.    

Ever since the Invincible Vajra Sect 's surroundings had been transformed into a world of battle spirits, they had lived for more than 500 years.    

To put it bluntly, they were tired of living.    

Moreover, they had lost their physical bodies and only their souls. They had lost most of their senses, and they could no longer experience the pleasures of the human body.    

To any normal human, this was a mental breakdown.    

Moreover, during these five hundred years, the demons would counterattack almost every hundred years.    

The sect's battle soul disciples, every single one of them could be said to have experienced hundreds of battles!    

Each of them had killed at least two or three Evil Demons!    

As for the higher sects' disciples, each of them had killed at least a hundred Evil Demons!    

The same scene rang out in the Beastmaster Sect of Longhu, Nine-Revolutions Pill Dao Sect, and Undying Ghastly Puppet Cult at the same time.    

But this time, many people's faces were covered with a layer of dark clouds.    

The movement of the evil devil this time was too fierce and unusual.    

They accurately killed the disciples in the danger zone, killing those with higher levels.    

Could it be that their intelligence had evolved to an extremely high level in these 100 years?    

Most importantly, many elite combatants had died.    

In the past, it was already very difficult for them to resist the devils, and they had only managed to push the Devil Domain to the center of Butterfly Valley of Hundred Flowers by a few thousand meters.    

After four hundred years of crazy battles, the territory that the devils had occupied had shrunk by more than half.    

But now, almost all the disciples and elders of the higher sects had been killed.    

Could they still hold on?    

"The vanguard of the Evil Demons is here!" The disciples who had been guarding outside the entrance of the Invincible Vajra Sect received the news through their Jade Scale.    

Everyone saw the scene outside the sect through the Jade Surface Scale.    

Black lines appeared on the horizon.    

At first, it was just very, very thin lines.    

Soon after, it covered heaven and earth as it arrived.    

The sky and the earth were all dyed by the dense Demonic Qi.    

The plants withered and withered, and the vicious beast scattered like birds and beasts.    

Those who ran slower were corroded by the Demonic Qi, and in an instant, they turned into demonized vicious beast. They widened their red eyes and sprinted towards the Invincible Vajra Sect .    

The reason why the land outside the sect was so vast was because every hundred years, these devils would come back again.    

Just the vanguard troops were already so arrogant!    

The few sentries that An planted in the sect were swallowed up by the vanguard forces in the blink of an eye.    

The disciples that were stationed there ran a little slower and were torn apart by the Evil Demons in an instant, turning into nutrients for them.    

A moment later, this disciple was reborn in the sect.    

However, the light on his body became much dimmer.    

If he died a few more times like this, even if his soul core was already bound to the sect, he would still truly die.    

"The Evil Demons are even stronger than last time." The disciple's face was pale.    

The disciples looked at each other, and they could see the fear and confusion in each other's eyes.
