Fast Upgrade System of being Immortal

"Have you heard? There are actually humans who call us trash and cowards, do you think we should fight back? Furthermore, that fellow actually dares to claim that he's betting his life, hehe! "    

    

A demon dweller with three horns on his head coldly laughed. Although he seemed to have thrown the question to someone else, one could tell from his expression.    

    

At this moment, his heart was filled with incomparable rage.    

    

He wanted nothing more than to tear this human apart. He was furious to the point that he was about to go berserk.    

    

However, he still endured it. This was not just his hatred.    

    

He didn't want to be the leader.    

    

Although he felt that a human would not have much of an impact on him, but what kind of methods did he know about?    

    

In a situation where he didn't understand the enemy, it was better to know himself and know his enemy.    

    

That was why he came here to ask the other demon dwellers.    

    

"Since others already say that we are trash, if we do not properly meet him, doesn't that mean that our name of trash has already been decided?"    

    

A giant guy stood up, and his words were loud enough to shake the eardrums of everyone present.    

    

Not only him, even the powerful demon dwellers all stood up. Although they didn't say anything, it could be seen from the expressions on their faces.    

    

At this moment, they were extremely dissatisfied.    

    

They had already been demon gods for quite some time, but no one had ever dared to look down on them like this. And now, it was even a human that came to their territory.    

    

How could this be tolerated?    

    

All of them stood up, their expressions turning extremely solemn.    

    

Seeing this, the three-horned demon god revealed a smile. With everyone advancing and retreating together, there was nothing for him to worry about.    

    

Just enough to let the people of the outside world know what a omnipotent demon god was.    

    

A mere human was simply courting death!    

    

"Before that, we must let those traitors know the consequences of betraying the Infernal domain!"    

    

"Ha!" Originally, I thought they were the kind of people that could be created, but I never expected that we would make a mistake and think that they are the pillars of the future. We are completely muddled. "    

    

At this moment, when all the demon gods thought of the source of this information, a cold aura was immediately released from their bodies.    

    

It was as if the entire sky had been frozen.    

    

Although they clearly knew that these Demon Emperors were forced to do so, doing so not only caused the demon gods to lose face.    

    

It had even caused a disturbance in the Infernal domain. This was something unforgivable.    

    

And in the eyes of all demon gods, whoever caused the chaos in the Infernal domain, no matter who it was, would have to pay a heavy price.    

    

It was with great difficulty that they were able to calm the Infernal domain down, but who knew that a black dragon like this would appear for a mere human?    

    

This made them feel as if this human was standing on their heads and pooping, which was even more difficult to accept.    

    

"Let's go …" "We will first take care of that arrogant human. After that, we will clean up some outsiders. It is time to properly wash up."    

    

"Perhaps it's because it's been too long since we've shown our faces, and some people have already forgotten about our methods. It seems that it's time for us to show our faces, or else we would truly lose all of our dignity."    

    

Although all the demon gods had a smile on their faces, one could tell from their aura that this was an absolutely ice-cold aura.    

    

This... But he was truly angry.
