The craziest upgrade system

Nie Yun looked at the huge bloody palace standing in the distance, and the sight in his eyes gradually became serious.

Because he had already explored this formation at the beginning. The scope of the formation was very large and the complexity was far beyond his imagination. With his entry-level formation realm, he wanted to break out of the constraints of this formation. , it’s simply a fantasy.

But now, Nie Yun was trapped inside, and he had no other good solution except this bloody palace.

Nie Yunchang exhaled and summoned the black flames to walk ahead to explore the way. One man and one python walked straight towards the bloody palace.

When Nie Yun actually came to this bloody palace, he found that the palace was already dilapidated, with huge cracks appearing on many corners, as if it might collapse at any time, as if it had experienced some kind of extremely terrible battle. Caused.

Nie Yun stood in front of the palace and saw clearly, frowning:

"The evil fire in Hei Yan's mouth is extremely aggressive, but when it hits this crumbling and dilapidated palace, it can't leave even a trace. What on earth did such a powerful palace go through to become like this? .”

One person and one python slowly stepped up the steps in front of the palace, one step, two steps, three steps... and finally arrived in front of the palace gate.

The scarlet door was very dilapidated, as if it was crumbling and might fall down at any time.

Divine consciousness is revealed.

At this moment, Nie Yun was surprised to find that his consciousness could not penetrate the dilapidated door in front of him!

He stretched out his hand and tried to push the door, but even with all his strength, he couldn't push it half an inch. He also tried to activate the 'Earth Escape Technique' to directly bypass the door and escape into the palace, but it was to no avail.

Nie Yun stopped where he was, staring at the scarlet door in front of him, as if thinking about something.

He opened his palm and grasped it, and the Wind Shadow Knife immediately appeared in his hand. He made a cut on his palm with force, and blood immediately flowed out. Then Nie Yun raised his bloody hand and printed it directly on the scarlet door in front of him.

As time passed by, there was still no movement at the door in front of him. Nie Yun smiled awkwardly:

"I'm a little pretentious. This door... doesn't seem to be opened like this."

He slowly took his hand back and wiped the blood on his hand with his clothes. At this moment, the cut on his hand had healed and scabbed in such a short period of time.

The wings of the white crane behind the vibration rose from the ground, surrounding the entire huge palace, not sparing any corner, and conducting a comprehensive investigation.

Nie Yun's heart palpitated more and more after observing at such a close range and experiencing the lingering aura left by the traces above the palace.

An hour later, Nie Yun returned to the scarlet door again.

"This door is the only door in the entire Blood Palace. Apart from this, there is no other entrance or exit. Since this door is here, it means there is definitely a way to enter... I may have missed something..."

Nie Yun's black eyes seemed to be twinkling with light, and he kept thinking in his mind: "Maybe... he has a mechanism..."

As soon as this idea appeared in Nie Yun's mind, it spread uncontrollably.

"But many places in front of this gate are dilapidated. If there is really a mechanism to get in, where should it be?"

Nie Yun was thinking as he kept walking, his eyes scanning the surroundings, not missing any detail.

Suddenly, his eyes lit up.

There is a floor tile on the side of the door, about two or three steps away. Its gap is slightly larger than the gap of the surrounding floor tiles by three-thirds.

This is very abnormal and is obviously a sign of frequent movement.

Nie Yun came to the floor tile and squatted down slowly, stretched out his hand, and pressed the floor tile tentatively, but the floor tile did not move at all.

Nie Yun frowned, but the strength in his hand did not decrease at all, but became stronger and stronger. Finally, under this huge force, the floor tile under him actually shook a little...

It's loose!

Seeing this, a smile flowed from the corner of Nie Yun's mouth.

Take out the Fengying Knife, carefully insert the blade vertically into the gap, and slowly and forcefully raise the corner of the floor tile.

Then Nie Yun grabbed the corner of the brick with his other hand and wanted to pick up the brick directly and put it aside, but as soon as he took hold of it, he felt something was wrong and was secretly surprised:

"What kind of material are these bricks made of? It's as big as a palm and weighs hundreds of kilograms!"

After a short pause, he moved the bricks aside, and sure enough, he found a stone ball the size of a fist underneath.

He reached out his hand, touched the stone ball, pressed it, and twisted it. After several attempts to no avail, Nie Yun thought for a moment, then took hold of the stone ball and pulled hard...

creak...

The sound came from the gate.

The scarlet door slowly opened under Nie Yun's gaze, revealing the scene of the palace inside.

After carefully placing the floor tiles back in place and cleaning away any traces of use, Nie Yun stepped into the door.

Crunchy...

With the sound of a mechanism, the door behind Nie Yun gradually closed.

In front of Nie Yun was a broader scene on the other side.

Looking up, this is an extremely spacious hall. In terms of area alone, this hall covers an area of ​​nearly a kilometer.

In the center of the hall, a huge black pyramid stands. A platform is cut out of the top of the tower, and there are stairs on both sides that can lead to the top.

Other than that, there is nothing else in this hall.

Nie Yun frowned and released black flames to explore the path ahead. After ensuring that there was no danger, he slowly climbed up the black pyramid.

After Nie Yun climbed up the black pyramid, a huge black throne stood in front of him.

On the throne, there was a corpse in tattered clothes, and nothing else.

But Nie Yun didn't dare to act rashly.

His eyes were deep and he stared closely at the corpse on the throne, waiting until Hei Yan came forward to explore the way.

Hei Yan's huge python body moved on the ground. After confirming that there was no danger, Nie Yun followed the path Hei Yan had taken, walked to the corpse, and looked around.

The man on the throne had been dead for who knows how many years, but Nie Yun still felt a strong sense of oppression.

This person must have been a peerless strong man in his lifetime!

"Except for this corpse, there is nothing else in the entire palace. So where should I get out?"

While Nie Yun was thinking, the changes suddenly increased.

On the throne, a ray of light suddenly shot out from the corpse's head and shot towards Nie Yun.

The entire underground space seemed to be in motion at this moment.

The speed of that ray of light was so fast that Nie Yun couldn't react at all...
