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

Lu Yuan closed the door.

Klaus didn't exchange pleasantries, put down his pen, and looked up at him.

"How do I do it?"

Lu Yuan stood in front of the table for two seconds, carefully considering his words.

"My pathway includes a symbiote that can devour the two types of damage you suffer."

Klaus didn't reply, his gaze fixed on Lu Yuan's face, waiting for him to finish speaking.

"During the process, you will feel something moving inside your body; do not resist it."

"If the strange power within you reacts, just suppress it."

When Klaus heard the word "symbiote," his eyes flickered slightly.

No further questions were asked.

He pulled his right hand out from under the table and placed it on the table, then began to unwrap the gauze. The gauze was wrapped several times and tied very tightly. When he unwrapped it, you could hear the slight friction sound of the fabric separating from his skin.

As the last layer is peeled off.

The bluish lines on my wrist were clearly visible under the light, spreading from my wrist along my forearm, flowing slowly under the skin, and even showing a tendency to spread deeper into the skin.

Then Klaus frowned slightly.

The bone-colored ring on the left ring finger flashed a faint dark green light.

The dark green light faded along the forearm, and the protective layer that had been covering the wound was actively removed.

Then Lu Yuan saw it.

The light remained enveloping the wound, and the blue lines he had seen in the office earlier were clearly Klaus's protective measures.

Now that the protection has faded.

The lines on my wrist changed; the blue turned into a dark red within seconds, seeping into the texture of my skin.

The edges of the lines began to spread deep into the forearm at a visible speed, as something that had been suppressed for a long time found a gap and was expanding outwards.

From the wrist to the middle of the forearm, the skin was covered with a fine, dark red network of lines. At several points where the lines intersected, the skin was slightly raised, and something was pulsating underneath.

Lu Yuan looked at the arm.

With this burden weighing on him, Klaus could still sit here writing reports, arranging actions, and setting traps for the Gray Contract Society.

Klaus placed his hand flat on the table; the black and red lines were still spreading, but at a slower pace. The period of explosive growth after the loss of protection was passing.

"Let's begin."

Lu Yuan didn't say anything more.

Close your eyes. The symbiotic connection transmits instructions.

Deep within the left eye, the worm of knowledge received a signal and swam out from the space inside the eyeball.

A tiny insect slid out from Lu Yuan's left eye, its surface shimmering with a faint tri-colored glow. It was much more robust than when Lu Yuan first saw it.

It swam down Lu Yuan's cheek to his fingertips, stopped, and its colorful light flickered under the lamp.

Klaus clearly saw it.

His whole body tensed up instinctively and almost simultaneously pulled back. His pupils contracted only slightly, but Lu Yuan was close enough to see it clearly.

His gaze was fixed on the insect's body, the tricolor shimmering light under the lamp reflected in his pupils.

There was a silence of about two seconds.

"A colorful knowledge-derived worm?"

Klaus spoke with certainty, his voice low.

Klaus knew all too well what the Knowledge-Deriving Worm meant. It was a forbidden product of the Tower of Knowledge, and the Night Watch headquarters had complete files on it. The fact that a second-tier Knowledge Transcendent possessed a Knowledge-Deriving Worm was extremely significant.

But in Lu Yuan's eyes, Klaus made the same mistake as "9" back then.

Both of them mistook the Worm of Knowledge for a fourth-order bizarre superhuman, the deputy chief of the Night Watch.

One is a key figure in the Gray Pact who controls the Lapis Lazuli Water. They are from completely different camps and different levels, yet their first reaction to the Worm of Knowledge is exactly the same.

They all mistook it for a knowledge-derived insect.

No one thought of it as a "knowledge worm," since it was clearly not found in any known archives, documents, or even rumors.

It is so rare that no one can correct the fact that it is "misidentified".

Lu Yuan did not correct him, but he had already made his own judgment.

"I'm about to begin."

As Lu Yuan spoke, the insect body transitioned from his fingertips to the skin of Klaus's wrist.

The moment they made contact, the worm of knowledge instantly burrowed in.

A surge of intense excitement instantly erupted through the symbiotic connection. The insect's entire state changed after entering Klaus's body. Emotions surged within the symbiotic connection, like something that had been starving for a long time entering a kitchen.

Lu Yuan immediately tightened the symbiotic connection.

He remembered every word of the note given during his research: "Entering the human body before you is no less than entering a kitchen." Klaus was a fourth-order bizarre superhuman, and everything inside his body was food for the insects.

If left unchecked, it might ingest the very things that sustain Klaus's life.

The worm of knowledge was confined, and the symbiotic connection emitted reluctant vibrations, but it obeyed the command.

Following Lu Yuan's instructions, they swam towards the target.

The symbiotic connection transmitted images, and the worm of knowledge touched the remnants of an old wound under the skin of the wrist.

It was some kind of crystallized damage embedded between the flesh and blood, like solidified shards of glass.

The knowledge-devouring insect, upon seeing this, did not hesitate and immediately began to devour it.

This residue, which is harmful to Klaus, is merely food to him.

Moreover, the knowledge worm, whose scope was restricted, became even more focused and devoured the crystallized fragments one by one.

Klaus felt a slight warmth moving in his wrist.

But he didn't move; he just twitched his right index finger, and his previously furrowed brows gradually relaxed.

Clearly, the therapeutic effect of the Knowledge Worm exceeded his original expectations. Instead of indiscriminately devouring his body, this thing precisely devoured the glass water that had invaded his body and was extremely difficult to remove.

In the last battle on the pipeline, the fourth-tier Gray Pact member who self-destructed left Klaus with extremely troublesome injuries, and after so many days, only a small part of them have been repaired.

It was actually eaten right away?!

Klaus was overwhelmed with a sense of awe.

The Worm of Knowledge has ventured deeper, its target the Sea of ​​Knowledge, and the aura that has invaded Klaus's body.

This thing appears blue-green in the symbiotic connection's vision.

The texture was completely different from the old wound, because the residual imprint of the sea of ​​knowledge was alive, like a blood-sucking worm, clinging to the edge of Klaus's barrier of reason, wriggling silently.

The worm of knowledge was clearly excited upon seeing this, and a pleasant vibration emanated from its symbiotic connection.

Clearly, this thing is an extremely rare delicacy for it.

The worm of knowledge swam over instantly, its colorful body covering the blue-green mark. The mark was then devoured piece by piece, much faster than the old wound. The things attached to the barrier of reason were torn off one by one and swallowed.

Klaus's right hand trembled violently.

He could feel something moving deep inside his body, and an indescribable feeling of something foreign came from his mind. He didn't make a sound, but a thin layer of sweat appeared on his forehead.

When the blue-green marks were being cleared to the middle, the Knowledge Worm, which had been happily making progress, suddenly stopped.

Because a dangerous aura locked onto him.

The worm of knowledge turned around somewhat stiffly, finally realizing that the source of the gaze was deep within Klaus's rational mind.

But the aura of that thing had nothing to do with the injury.

It is something ancient, profound, and carrying a sense of oppression.

When Lu Yuan sensed this place, he had roughly guessed that the thing was likely Klaus's "God." Lu Yuan still remembered the amber sealing method that Klaus had taught him before.

Lu Yuan calmed the Knowledge Worm through symbiotic connection, and the Knowledge Worm gradually calmed down.

At the same time, the bone-colored ring on Klaus's left ring finger trembled for less than half a second at the moment the Worm of Knowledge was frightened, and then fell silent.

Klaus clenched his left hand under the table.

He was clearly suppressing something.

And so, the worm of knowledge, having consumed the two kinds of damage residue, returned along the same path, emerging from the wrist and swimming back to Lu Yuan's left eye along the fingertips.

The symbiotic bond became clear again, and the insects conveyed a sense of satisfaction.

Two lines of gray-white text jumped across the edge of my field of vision.

[Taboo Studies - Seeker of Knowledge: +0.3...73.1/100]

[Current Status of Bronze City: +0.2...18.2/50]

Some of the food we ate came back as feedback, although the numbers were very small, but there was definitely some.

Lu Yuan opened his eyes.

The dark red lines on Klaus's wrist faded visibly within seconds, the color changing from dark to light until only a faint trace remained, and his complexion returned to a healthy rosy hue.

Klaus moved his wrist in disbelief, clenching and unclenching his fist, and found that the force was completely different from before.

After a brief silence of a few seconds.

How long will it take to fully recover?

"Use the prescribed medication from the pharmacy for two or three days."

After a two-second silence, Klaus looked at Lu Yuan.

"Lu Yuan, what you possess far exceeds my expectations."

Lu Yuan didn't respond, and Klaus didn't press for the source either; his level and experience dictated that he shouldn't ask at this time.

Klaus took the initiative to speak.

"Frantz, you've seen his condition, your symbiote... can it be cured?"

Lu Yuan paused for a moment.

"He's different from you. The remnants of the Sea of ​​Knowledge run too deep; the foundation of his reason is on the verge of collapse. My symbiote entering him could very well shatter his last vestiges of consciousness."

"I estimate the success rate is only about 10%, there's no good way to achieve it."

Klaus's finger paused on the table for a moment.

"One-tenth."

Klaus did not ask Lu Yuan to take any risks, and then let out a soft sigh.

"Berlen took him away early on; the conditions at headquarters are better than ours."

Both of them understood Franz's fate; he would most likely be transferred from his original position, and this blow to his sanity might be one he never recovered from.

Klaus took a document from the drawer, outlining the procedures for the bottom-flipping operation.

"The day after tomorrow morning, all the nobles of the inner city will be summoned to the main hall of the Earl's mansion. Those who do not come will be sent by the Iron Guard."

He pushed the document in front of Lu Yuan.

"Headquarters sent someone over specifically to handle this. You'll see when you meet them."

"Your task is to observe discreetly, and notify me if you discover anything unusual. You're not part of the main force this time; you don't need to be at the forefront."

Lu Yuan nodded.

"Go to sleep. You need to be awake the day after tomorrow."

As Lu Yuan left the office, the oil lamps in the corridor were still burning, though the flames were smaller than when he arrived.

Back in the room.

It was still dark.

Lu Yuan decided not to continue sleeping.

He picked up his pen and the prepared letter paper, but for a moment he didn't know what to write.
