Invincible Super System Modifier

He didn't see any traces of humans.    

"Let's walk inside."    

He took a step forward and walked through the canyon filled with monsters, wanting to reach the end of the canyon.    

As the vibration waves spread out, the air here was no longer as muddy as before.    

Lin Fei could see very far away.    

He walked forward for a few minutes and did not see any more monsters.    

Because they had all died in the vibration waves just now.    

He walked forward for a few more minutes.    

Half of the canyon had been cleared.    

Just as Lin Fei was guessing that this should be a real canyon, a damaged car appeared in front of him.    

This car was the same as the monster he had just met. It had red spots all over its surface.    

There were also purple stones that spread out, as if they were eating away at this car.    

"Why is there a car here?"    

Lin Fei was surprised.    

This place looked like a canyon.    

Could it be that his initial guess was correct?    

This place was indeed related to another country?    

He quickly ran forward and soon saw something new.    

It was a metal chair, but it was already rusty and covered in red spots.    

Lin Fei saw the floor.    

The floor seemed to be made of metal too. It was full of red spots, as if it had some kind of skin disease.    

"Was this actually a road?"    

Lin Fei was surprised and continued to walk forward.    

When he walked out of the canyon, he suddenly stopped because he clearly saw a huge city in front of him.    

This city was filled with tall buildings, it was no different from the high-tech cities he had seen before.    

Obviously, they were all at the same level of technology.    

However, this city in front of him did not have a protective shield.    

The city walls were also covered with red stripes.    

Lin Fei walked over and used his X-ray vision to check a few times, but he did not see a single living person.    

There were only those monsters inside.    

He immediately guessed, "The humans here were suddenly attacked by those monsters!"    

Lin Fei walked into the ruined city.    

Those monsters immediately discovered him.    

Boom!    

Lin Fei couldn't be bothered with them. He blew a gust of wind and killed all the monsters here.    

"How long has this city been attacked for?"    

He saw many bones on the ground.    

It seemed like it had been at least three years.    

"Are all the people in this city dead? Did anyone escape? Or did they stay?"    

Lin Fei flew up high and landed on the highest floor. He used his X-ray vision to look around again.    

But he did not see anything.    

"Hmm?"    

At this moment, he found a box beside him.    

The box was covered with dust, as if it had been here for a long time.    

"Who put a box in such a place?"    

Lin Fei reached out his hand to the box, but before he could touch it, the box automatically opened.    

A piece of paper quietly lay at the bottom of the box.    

Lin Fei felt a little strange. Could it be that someone knew he was coming?    

"Pick it up and take a look."    

He grabbed at the air, and the piece of paper flew up and landed in his hand.    

Chen Feng opened the piece of paper and saw the words he recognized on it.    

"I will write down this piece of paper with despair. Maybe one year later, or ten years later, you will find me."    

"I hope that when you come here, you will see a beautiful and harmonious city, not a world full of corrupted creatures."    

"If you are unlucky and it is the latter, then the following words are what I want to say to you."
