I can see experience bars after being transported to another world.

Lu Yuan withdrew his attention and turned his gaze back to the Blue Knight.

The Blue Knight was standing two steps behind him, his whole body tense.

The silk threads around her body trembled violently, her azure eyes reflected the eerie inscriptions swirling in the space, her lips were pressed into a straight line, and her expression was much more gloomy than before.

Because at the far end of this empty space, in the direction where the copper wall disappears, there is something extremely dangerous.

The Blue Knight's extraordinary power was issuing frantic warnings, far more intense than any moment had passed in the passage.

This sense of oppression was something she had only experienced once before, since leaving the Knight Academy, when she was with the Grand Knight Commander.

She suddenly remembered what the Grand Knight Commander had said to her before he sent her to Bronze City.

The Grand Knight gave her something that was almost prophetic.

Bronze City offers her a path to the fifth tier, but she will encounter life-threatening dangers and unforgettable things and beings there, prompting her to think carefully before returning.

The Blue Knight didn't hesitate much and agreed immediately. She had never been afraid of death.

None of the graduates of the Knight Academy are afraid of death, because those who are afraid of death cannot even get in.

Even if it's forbidden, even if it's a legendary existence, so what? She's not willing to be stuck at the fourth rank for her entire life; she'd rather risk her life.

But now, standing in this space submerged in the strange, rotating inscriptions, and sensing the existence directly in front of her that far exceeded her imagination, the Blue Knight couldn't help but feel a long-forgotten emotion: fear.

She'd seen enemies she couldn't defeat before, but that was a different matter. The thing ahead was worlds apart from her; she didn't even have the qualifications to fight it.

The Blue Knight took a deep breath, the air carrying a faint smell of rust, but she didn't pay it any mind. After a brief moment of calm, she slowly exhaled, her gaze returning to Lu Yuan's back.

The young man, at level two, was carrying a marching lantern and walking towards the original direction of the copper wall. His steps were steady, and there was no sign of him being affected at all.

Seeing this, the Blue Knight no longer hesitated, took a step forward, and followed closely behind.

Lu Yuan took a few steps toward the original direction of the copper wall, and gray and white characters began to appear frantically.

You are approaching a forbidden aura. Please move away immediately.

Lu Yuan ignored him and took two more steps forward.

[Advanced - Mysterious Inscription: +1...22.5/50]

[Advanced - Mysterious Inscription: +1...23.5/50]

[Advanced - Mysterious Inscription: +1...24.5/50]

Grayish-white characters kept appearing at the edge of his vision, too fast for him to read them one by one. His experience with the strange inscriptions increased rapidly, increasing a little with each step forward, so dense that he had never seen anything like it before.

Immediately afterwards, another line of text appeared.

[Forbidden Studies - Seeker of Knowledge: +1...80.9/100]

Lu Yuan's heart suddenly raced. His long-dormant experience in forbidden arts had actually increased.

This was one of the only experience points he couldn't farm, just like his sanity level IV.

No matter how much he meditated or practiced his defense, his rationality IV level wouldn't increase. His defense level had increased by seven or eight points during this period of practice, but his rationality IV level remained unchanged, except for a few points when his rationality overflowed a while ago.

The same principle applies to taboo studies.

While one can gradually accumulate knowledge of bizarre inscription techniques through engraving and learning related knowledge, the experience of forbidden arts and rationality remains stagnant unless one actively seeks out unknown forbidden existences or special existences that one has never encountered before.

Right now, he's just standing in this vortex of strange inscriptions, doing nothing, yet his experience is increasing on its own.

The amount of material he accomplished in these few steps was equivalent to several months of arduous study at the branch.

Lu Yuan suppressed his surprise and continued walking without stopping.

Now is not the time to dwell on experience; he needs to figure out two things first: how deep the copper wall below has sunk, and whether the fifth fragment is related to it.

He continued forward, holding the war light.

The flame inside the copper-framed lantern dimmed segment by segment, and the illuminated area shrank from four or five steps to about two steps.

Further on, the light was so close to the wick that it could only illuminate his hands and a small patch of ground beneath his feet.

Just then, the ground beneath their feet suddenly disappeared.

There was no way forward for Lu Yuan; all that remained was a deep abyss.

He glanced down and saw that the light from the marching lights had faded, illuminating the cliff face about half a person's height before disappearing. Below that, there was only pure darkness, with not a single ray of light able to penetrate.

A cold wind surged up from below, carrying an indescribable scent that was actually quite pleasant.

This is where the copper wall should have been, but now it's gone, leaving only a huge gap.

Lu Yuan looked along the edge to both sides and realized that the copper wall was much larger than he had thought.

The width and height of the gap were beyond his imagination. Even with his own divine sense, he could only see that there was no end in sight on the left and right sides.

The area that collapsed is probably not much different from the entire Pagoda of Learning.

This huge wall just sank completely like that.

She glanced down, her brows furrowed, her deep blue eyes contrasting sharply with the darkness below.

Neither of them spoke, clearly stunned by the sight before them.

Just then, a faint ray of light pierced through the deep darkness.

It was a pale golden light, faint and elusive, seeping up from the deepest depths of darkness.

The light was so faint that Lu Yuan initially thought he was seeing things. But after staring at it for a few moments, he confirmed that there was indeed something emitting light in the endless abyss.

However, the golden light was not pure; it seemed to have been tainted by darkness.

The Blue Knight saw it too.

As if sensing something, the threads on her body suddenly tightened, and she took half a step back before abruptly stopping.

Lu Yuan turned and glanced at her. "Shall we go down?"

The Blue Knight's gaze shifted from the bottom of the abyss back to his face.

Without hesitation, she gave her answer: "Go down."

Lu Yuan looked down at the cliff face.

The almost vertical cross-section, a mixture of stone and bronze, is covered with bizarre, rotating inscriptions, so dense that there is nowhere to even step.

He reached out and touched the edge of the cliff face; the strange, swirling inscriptions touched his hand but still veered away.

He didn't care, but the Blue Knight couldn't touch this kind of thing.

"The most crucial thing is, I can't climb these walls," Lu Yuan said honestly. "And you can't touch the inscriptions around here, so how are you going to get down?"

He was right.

This near-vertical cliff face is not something that a second-order knowledge transcendent can climb freely, even with time synchronization enabled. It is only possible to descend if one has prepared ropes or something similar for securing it.

The Blue Knight looked down at the Abyss, then at Lu Yuan, and after a brief silence, gave his answer.

"You're carrying me on your back."

Lu Yuan was stunned, not expecting the Blue Knight to offer such a solution.

"My silk threads can cling to cliff faces," the Blue Knight said quickly, "as long as they don't directly touch the inscriptions. You hold them off for me, and I'll help you climb the wall."

Lu Yuan went through the plan in his mind. It was theoretically feasible and sounded fine.

"Okay."

The next moment, the Blue Knight did not hesitate. He flashed behind Lu Yuan, wrapped his legs around his waist, and hung up on him.

Lu Yuan then realized that the Blue Knight was not actually that heavy, about the size of an adult male, and carrying her on his back did not affect his movements at all.

But her strength was outrageous. Her legs wrapped around his waist, and the moment she tightened, Lu Yuan almost thought he was going to be crushed.

That force carried a kind of pure destructive power, locked around his waist, as steady as could be.

Even through the leather armor, he could feel that the Blue Knight's leg, which was locked around his waist, was very thin, but underneath it was wrapped in an almost explosive sense of muscle, with a touch of elasticity.

The Blue Knight was more than half a head taller than him.

With her hanging behind him like this, Lu Yuan's head was roughly touching her chest, and the way they were stacked together didn't look good.

He carried a lantern, with a fully armed fourth-tier knight, taller than himself, on his back, making him look like he was carrying a huge vat.

Lu Yuan couldn't help but swallow hard. It wasn't that he had any ulterior motives upon encountering the Blue Knight, but rather that he felt those legs could twist him in two at any moment.

Thinking about it this way, he felt a sense of security. As long as the Blue Knight didn't have any problems, he probably wouldn't have any problems either.

At the same time, the light blue threads on the Blue Knight's body spread out, emerging from the gaps in her cloak and armor, clinging to Lu Yuan's body, wrapping around him from his shoulders to his waist, and completely enveloping him.

The moment the silk thread touched him, Lu Yuan trembled.

An extremely strong yet clean force surged in along the silk thread, washing away the restlessness and frustration that had been weighing on my chest. My mind became much clearer, and my breathing became smoother.

Previously, those strange, rotating inscriptions could add a slight influence to the line of sight, but now they pose no disturbance whatsoever.

At the same time, he felt his body being cleansed from the inside out by this force, and an indescribable sense of fullness rose in his limbs, as if his strength was much greater than usual.

The two of them were thus wrapped up like mummies by these light blue silk threads.

This is clearly the effect of the Blue Knight's extraordinary weapon.

To Lu Yuan's surprise, he seemed to be able to subtly control these threads.

He tried to move his mind, and the silk thread wrapped around his arm tightened and then loosened, reaching out to deliberately block a strange, rotating inscription nearby.

After these threads fell onto him, they seemed to understand his thoughts, as if they had grown out of his own body.

The Blue Knight felt his threads being controlled by Lu Yuan, and a hint of indescribable emotion flashed in his eyes.

Is her rationality really that high? Even higher than mine? She thought to herself, but said nothing aloud.

Lu Yuan hung the marching light on his waist, freeing up his hands.

The silk thread extended out from between his ten fingers, firmly gripping the edge of the cliff, easily supporting the weight of the two people.

He checked himself over to make sure everything was alright, then looked at the fading golden light at the bottom of the abyss and said to those behind him, "Hold on tight."

The Blue Knight instinctively tightened his legs even more.

Lu Yuan couldn't help but exhale, but didn't say anything more. He narrowed his eyes and manipulated the silk threads, tumbling down the edge of the bottomless cliff.
