Lin Fei is constantly looking for survivors in this dangerous world.

But at the same time.

Every few minutes, he will easily create some solid castles.

They are all made of steel.

Even if the ape-man was resurrected again and then came to tear down these castles, there would be no way to shake a single cent.

The world is lifeless.

And now, Lin Fei is manually adding life to this place.

As long as one person can live in the city.

Then his efforts are totally worth it.

But this place is really too huge, Lin Fei searched for a while, but did not see other human beings.

Dozens of cities have been built.

Click!

Just when Lin Fei was puzzled.

There was a loud noise above his head.

Lin Fei immediately looked up.

A flash of lightning cut through the dim sky.

It was a blood-red lightning, and accompanied by the lightning, there were two bright red lights.

It seems to be a pair of eyes.

Slowly approaching from the dark storm.

Others may not be able to see clearly, but Lin Fei's perspective has already seen this monster clearly.

That is a huge flying dragon.

A pair of wings, overwhelming.

Every instigation will bring up a storm.

This flying dragon was covered with black scale armor, his eyes were as red as blood, and his head had sharp horns.

Sharp teeth protruded from the mouth of the flying dragon.

Like a monster running out of hell.

The flying dragon saw Lin Fei and was slowly approaching.

Lin Fei did not run away, but was looking at the flying dragon in front of him. Will this thing know the news of the devil?

"This thing seems to have appeared suddenly?"

When he flew by just now, he had not seen this thing.

And when he just built a castle.

Lightning appeared.

It was as if someone suddenly threw this flying dragon in front of him.

Lin Fei suddenly had a flash of inspiration, and a bold guess appeared in his heart.

"Maybe, this world is man-made." He guessed.

This world does not exist.

People fall asleep safely, but because of what the devil has done.

Therefore, after people fall asleep, they will enter a dangerous world.

Only safe.

Humans will appear in this world.

Otherwise, according to the theory of evolution, it is the creatures that have strong bodies and can rest for a long time to rule the world.

Rather than being fragile and insignificant.

In terms of fighting, bears and tigers are stronger than humans.

Only in this way can you gain an advantage in a dangerous area.

Lin Fei thought of more details, the existence of this world, and the current state of mankind.

There is simply no way to explain it scientifically.

Because humans are now the weaker side.

There is no way to gain a foothold in this world, let alone develop to the current level of urban agglomeration.

Even if it evolves into an adult, it is impossible.

"The devil is not in this world."

Lin Fei had a general idea in his mind.

"Secondly, the demon master this time may be a human being."

"He is doing some kind of experiment."

Is it right?

Just ask the flying dragon above your head.

Lin Fei looked up and looked at Feilong calmly.

"Hello, may I ask, do you know the devil?" Lin Fei asked.

Feilong did not answer, but spouted a flame.

But Lin Fei didn't need its answer anymore.

Because he already got the answer he wanted.

This flying dragon didn't know the existence of the devil.
