Invincible Super System Modifier

This was a blue-green flame.    

The temperature was extremely high, able to incinerate everything.    

However, it didn't have any effect on Lin Fei. With a wave of his hand, all the flames returned to him.    

The ferocious-looking flying dragon didn't even know what had happened.    

It was swallowed by the flames.    

Then it turned into ashes, blown away by the wind.    

Lin Fei didn't care about the life or death of this flying dragon, because this thing was very likely man-made.    

Now he wanted to do an experiment.    

He wanted to see with his own eyes the monster appear from the void of space.    

Or rather, it suddenly appeared in front of him.    

Only then could he be sure that these monsters were secretly controlled by someone.    

If the monsters in this world kept spawning.    

Then previously, he had used the ball of light to kill many of them.    

Now, those areas were still bare, with no monsters at all.    

This meant that the monsters were not spawned in this world.    

Otherwise, monsters would appear in that place again.    

And the numbers were stable.    

Just as much as the last time.    

Lin Fei continued to fly forward, shortening the distance between each castle.    

At the same time, he made the castle even bigger.    

He wanted to create a bigger commotion and lure the mastermind out.    

Just ten minutes ago.    

Boom!    

Another flash of lightning.    

Lin Fei immediately raised his head. There were layers of dark clouds there.    

Through his X-ray vision, he did not find anything, but a few seconds had just passed.    

A huge red figure appeared out of thin air.    

It was a huge humanoid monster.    

Lin Fei only took a glance at it before he raised his hand and killed it.    

He continued forward.    

He continued to build the castle quickly.    

With the birth of this monster, Lin Fei basically confirmed his thoughts.    

But he had just built two castles.    

Lightning appeared once again in the sky.    

The time it took for a powerful monster to appear was shortened.    

Lin Fei was completely sure that there was something watching him from the shadows.    

And this thing must be a human in the outside world.    

He raised his hand and killed the three monsters that fell down.    

Then he used [Awakening] on himself.    

After waking up from reality, Lin Fei immediately activated his X-ray vision.    

He wanted to see if there was anyone who was hostile towards him.    

If there was a red dot.    

That meant that person was most likely a Demon Lord.    

Unfortunately, there was no red dot.    

Maybe.    

But it was too small, so he didn't notice.    

"Wu ~"    

At this moment, Ye Yuxue woke up.    

She was originally not very tired.    

So after sleeping for a few hours, she woke up.    

On the other hand, Yun Ruoyan was still sleeping soundly. She would probably need another night to wake up.    

"Lin Fei, what are you doing?"    

When Ye Yuxue woke up, she noticed the small room that Lin Fei had made.    

She said in surprise, "You went in again?"    

She was smart enough to guess something immediately.    

"Do you think the Demon Lord is in that world?"    

Ye Yuxue carefully thought about it.    

This was very likely.    

Because this was the only way to explain why the other place was so dangerous.    

"I originally thought so."    

Lin Fei said, "But just now, I realized that things were not that simple."    

What he was going to encounter.    

He also told Ye Yuxue about his previous guess and conclusion.    

"The Demon Lord might be a human?"    

Ye Yuxue's face was solemn.    

She knew about the evolution of living beings. Survival of the fittest.    

If one wanted to live, they had to make changes according to the environment.
