The 80th catacomb!

The resting place of the Three-Winged Bird.

The moment Klein stepped into the catacomb, he felt a strong gust of wind.

Anything that was slightly light would be blown away.

Thankfully, Klein's physical fitness was much stronger than before

Furthermore, Klein had dived in, so no matter how strong the wind was, Klein didn't panic.

Klein chose a direction and poked his head out of the ground.

He observed the location of the Three-Winged Bird.

The Three-Winged Bird was currently resting on a tree.

The tree was very large.

Klein observed carefully and realized that the wind came from the tree's hole!

'I wonder what's inside this tree hole?' Klein thought to himself.

However, Klein only thought for a moment before placing his gaze on the Three-Winged Bird.

The Three-Winged Bird looked different from ordinary birds.

Its head was slightly larger, and its body was about two meters tall.

It was taller than Klein.

Each of its three pairs of wings was larger than the other.

Even when it was asleep, its wings were fully spread.

Klein looked at the Three-Winged Bird and fell into deep thought.

He was thinking about what he would do if his speed was inferior to the Three-Winged Bird...

After all, the most powerful move was speed.

Even if he couldn't beat it, he could at least run, right?

Therefore, if Klein couldn't beat it, there was only one way to do that, which was to dive underground!

Otherwise, he wouldn't be able to run even if he wanted to.

Furthermore, if Klein's speed was inferior to the Three-Winged Bird, even if the Three-Winged Bird wasn't his match, Klein wouldn't be able to do anything to it.

That was because Klein couldn't catch it at all.

Therefore, if Klein wanted to defeat the Three-Winged Bird, he could only do so if his speed was faster than the Three-Winged Bird's.

Klein looked coldly at the Three-Winged Bird, having already made up his mind.

Firebomb!

A huge fireball was fired from Klein's hand, smashing towards the sleeping Three-Winged Bird.

However, just as the fireball was about to reach the Three-Winged Bird, the Three-Winged Bird suddenly woke up.

In an instant, the Three-Winged Bird disappeared from its original spot.

'So fast!'

Klein was secretly amazed.

The Three-Winged Bird's speed was indeed extraordinary!

However, Klein was instantly wiped clean. He didn't hide any longer and directly used the advanced aircraft to fly into the air.

"Rockets!"

Dozens of rockets were rapidly fired at the other party.

Without exception, all of them were dodged by the Three-Winged Bird.

After the Three-Winged Bird confirmed Klein's location, it let out a cry and flew towards Klein, wanting to attack him.

Klein wasn't a pushover either. He directly activated the advanced aircraft and turned around, dodging the Three-Winged Bird's attack.

'From the looks of it, I'm also very fast.'

During Klein's previous test, he didn't use the full range of the aircraft. Due to the lack of space, he would have an accident if he used it.

But it was different now.

The catacomb was very spacious.

In addition to the Three-Winged Bird's fierce attack, if Klein didn't dodge in time, he would probably be reduced to meat paste.

The Three-Winged Bird clearly didn't expect Klein to dodge its attack, and a look of shock flashed in its eyes.

However, it quickly flapped its wings and attacked Klein again.

This time, its speed was even faster than before.

However, Klein immediately switched on the aircraft with all his might and dodged the Three-Winged Bird's attack once again.

The Three-Winged Bird was completely dumbfounded.

He actually dodged its attack twice in a row?

What was this fellow's situation?

Klein sneered and said, "Your speed doesn't seem to be that fast."

Klein was already certain that his speed was higher than the Three-Winged Bird's.

Therefore, Klein flew directly to the Three-Winged Bird and firmly grabbed it.

The Three-Winged Bird panicked and wanted to throw Klein down.

However, Klein grabbed it firmly and didn't give the Three-Winged Bird the chance to do so.

The Three-Winged Bird was in despair.

It realized that there was a cave in front of it.

If he went through it, Klein would definitely crash into the entrance of the cave!

Therefore, the Three-Winged Bird changed its direction and rushed towards the entrance of the cave at its fastest speed.

Klein wasn't stupid. He naturally saw through the Three-Winged Bird's intentions.

Therefore, before the Three-Winged Bird reached the entrance of the cave, Klein had already ignited the flames in his hand.

The reason why he did this was because Klein knew that no matter how he attacked, the Three-Winged Bird would definitely dodge.

Therefore, when Klein grabbed the Three-Winged Bird, it was unable to dodge no matter what.

"Have a taste of my fire!" Klein said coldly.

A huge flame devoured the Three-Winged Bird.

Boom!

The Three-Winged Bird lost its ability to fly and crashed to the ground.

There was a loud bang.

Smoke and dust rose.

The Three-Winged Bird was dead.

Klein walked down from the sky and snorted inwardly when he saw the Three-Winged Bird's miserable state.

'That's all?'

From the looks of it, his current advanced aircraft was fast enough.

This was very good news, making Klein feel even more confident.

Klein opened the runic base and returned to the castle.

Klein had been feeling a little sleepy for the past few days.

Furthermore, he had gained a lot recently. Klein felt that he could take a good rest.

Klein let Little Fox and Little Wind have a good rest as well.

Little Wind and Little Fox were very happy and went to play by themselves.

Alu and Lulu were very energetic. They weren't tired from their usual work, and taking care of plants was already a very happy thing for them.

Therefore, they didn't feel uncomfortable, nor did they feel tired.

After Klein arranged everything, he checked his current supplies. Even if Klein didn't do anything, it was enough for them to survive in the catacombs world for a month.

Klein planned to rest for two days.

When he returned to his room, Klein felt a little tired and fell asleep.

After arriving in the catacombs world, Klein hadn't slept so comfortably in a long time.

Even though he was far ahead of all the players, Klein only slept six hours a day.

The rest of the time, he was thinking of ways to improve himself.

He would either search the catacombs or conduct business in the mall.

In short, he never stopped.

The moment Klein laid down on his bed, he fell asleep.

In his dream, he dreamed that he had returned to his original world.

Everyone was the same as before.

...

When Klein woke up again, it was three days later.

In an attempt to wake himself up, Klein washed his face with water.

With this washing, Klein instantly became much more energetic.

At that moment, the first thing Klein wanted to do was to understand what had happened in the past three days.

After all, in the catacombs world, there was a possibility of something extremely huge happening every second.

Klein immediately switched on the world channel and began to read everyone's conversation.

However, when Klein casually flipped through it, he frowned.

"During the three days I slept, quite a few things actually happened."
