Klein took a step forward, but just as he moved, there was a series of thuds under his feet.

Klein looked down and saw that the path from the cave to the forest was about 20 meters long. There were actually white bones laid out on the ground!

He squatted down to examine them carefully. They were all humans.

Furthermore, their deaths were extremely tragic. Some had been poisoned to death, and their bones had turned black.

Some were blasted apart, and not a single good bone could be found in their bodies.

Some were shot through the space between their eyebrows by an arrow.

Looking at everything in front of him, Klein felt a chill run down his spine.

It seemed like the system had underestimated them.

There were skeletons all over the ground. At least a hundred people had come here.

But these hundred people hadn't managed to take down the platinum treasure chest in the middle of the forest. It seemed like this place was even more dangerous than he had imagined!

After seeing this, Klein's gaze changed as he looked at the lush forest in front of him.

There seemed to be countless monsters that ate humans in places that he couldn't see in the forest. Once Klein stepped in, they would devour him!

At this moment, Klein didn't dare to be careless. There was a powerful barrier in front of him. If he were a monster, he wouldn't easily come out when he encountered a powerful enemy. Instead, he would use the terrain to surround and kill.

After all, they were more familiar with the environment of the forest than he was.

Therefore, Klein couldn't take the initiative to enter!

The only way to break the situation was to break their advantage!

With this thought in mind, Klein gripped the Endless Sword in his hand. Then, he raised it and waved it forcefully. Instantly, a terrifying saber beam shot out from the endless blade.

Rip!

The saber beam was extremely terrifying. Wherever it passed, the world would change color and the earth would quake.

All the trees didn't even last a minute before they were instantly smashed into smithereens and sent flying into the sky.

As the saber beam swept past, everything inside was revealed.

Klein looked over after the dust settled.

At this moment, all the lush greenery had turned into flat ground. Other than the platinum treasure chest in the middle, there was nothing else that stood up.

As expected, Klein's guess was right.

These monsters were definitely not that easy to deal with.

They should have run away the moment the saber beam approached.

This made Klein slightly disappointed. Forget about the Armored Scorpion and Harpy. They both had innate skills, so it was still very easy for them to dodge the saber beam.

However, the Rouge Archer was a thorn in Klein's heart.

He thought that he could take advantage of the situation to finish it off, but he didn't expect that the archer wasn't as simple as he thought!

'Then where are they now?'

Klein looked around.

As the light from the blade disappeared, the surroundings fell silent once again.

It was as though nothing had happened here. Everything was calm and there was no danger.

But at that moment, a sound reached Klein's ears.

Whoosh!

No, there was more than one!

Whoosh!

Whoosh!

Whoosh!

There were at least five sounds.

Klein hurriedly looked up, his eyes staring straight ahead. However, there was only an increasing sound ahead, and he couldn't see what was attacking him.

'Could it be an illusion?'

Klein couldn't help but think.

But suddenly, Klein's temple frantically warned him.

'No, it should be the Rouge Archer!'

Klein recalled that the system had once said that there was a Rouge Archer inside. Clearly, this move, which only had sound but no substance, was the Rouge Archer's move.

However, Klein was familiar with this move. It was the Blood Ape's move that had left Klein in a very passive position.

But clearly, this Rouge Archer was more proficient in invisibility than the Blood Ape. It directly concealed its physical body and only exposed its voice!

It couldn't be said that the Rouge Archer was weak just because it didn't conceal its voice. In fact, it wasn't the case.

In an empty environment, you knew that the enemy was around, but you weren't sure where the enemy was.

As for the enemy, he was observing you coldly from where he was.

Suddenly, the enemy shot an invisible bow and arrow. The whistling sound instantly broke the silence, letting you know that there was an attack, but you didn't know where it came from. This kind of powerful psychological pressure wasn't something an ordinary person could withstand!

With this in mind, Klein didn't dare to be careless. He waved his hand and cast an earth spell. The ground in front of him rumbled, and soon, the ground beneath him was pulled up and three layers of earth walls were set up in front of Klein.

Just as Klein set up the earth walls, there were instantly loud bangs and tremors from the earth walls.

Clearly, the arrows had arrived!

But in the end, they were blocked by the earth walls. Clearly, the power of the arrows was insufficient.

This was Klein's first thought.

Then, he removed the earth walls and carefully observed his surroundings.

Dodging wasn't the way to defeat them.

Sure enough, Klein removed the earthen wall and the second wave of attacks arrived.

This time, the sound was even faster, as though someone was dragging a piece of cloth across the surface of the water.

There was a muffled sound.

'This is?'

When Klein heard the sound, he suddenly had a familiar feeling.

Suddenly, a gust of wind pressure rushed over, startling Klein's long hair.

Klein hurriedly looked up.

No wonder it was familiar. It was the sound of wind pressure!

At that moment, a hundred meters in front of Klein, there was a black shadow standing in the air. It opened its mouth and emitted a terrifying sound wave as it headed straight for Klein.

Klein couldn't care less about who the figure was, so he could only react in a hurry.

Sound waves were a form of wind usage.

The best weapon to resist sound waves wasn't the Endless Sword, but water!

The transmission of water was slower than that of earth.

With this in mind, Klein cast the earth runes again. Then, with a wave of his hand, countless pieces of earth flew up into the air, forming a thick stone wall directly above Klein.

With a few dull thuds, the sound waves were blocked.

And more than half of Klein's earth wall was gone.

Clearly, the power of the sound waves couldn't be underestimated!

Just as Klein was about to take a look at the figure in the sky, there was a sudden movement on the ground.

The ground in front of Klein seemed to have been cooked. It kept rolling as if something was about to come out.

Klein suddenly thought of the third monster in the cave, the Armored Scorpion!

Just as he had this thought, a pitch-black tail broke out of the ground and headed straight for Klein's face.

Klein didn't dare to be careless. The venom of a scorpion's tail was extremely terrifying. In his previous life, he could easily take down an elephant. The environment of the catacomb was even more terrifying than his previous life. Who could say that the scorpions here hadn't mutated?

With this in mind, Klein hurriedly took out his Endless Sword and swung it.

With a boom, the scorpion's tail was severed by Klein.

But to Klein's surprise, not only did the scorpion not run, it even crawled out from the ground.

The Armored Scorpion was very large, about the size of a locomotive.

Klein stood in front of it, appearing very weak.

But that was only its size. What was most terrifying was its two pairs of pincers.

The two pairs on the left and right were like a huge basketball rack. The concave teeth were large and sharp. Clearly, as long as it caught Klein, he would definitely die a miserable death!
