Starting with Proficiency Panel

The three were all skilled and courageous, and after asking Lu Ren for some fluorescent sticks, they left without mentioning Jack, who had undergone biomechanical modification.

Nosnov, being an extraordinary powerhouse focused on cultivating spirit and physique, found ancient relics like these incredibly tempting. Inside might lie something that could help him advance further.

Whether it's a method of cultivation or treasures that could directly enhance the human body.

This is not without precedent.

This is not without precedent. Even inside the Security Bureau, there are living examples. It's said that the Southern Guardian Li Tianming consumed a Nine-Turn Golden Pill of extremely ancient origin.

Even with most of its medicinal power lost, it still allowed him to step into an extremely bright awakening and advanced state.

Such ancient relics, built in a style akin to Eastern China ancient architecture, got Nosnov, a keen web novel reader, excited as he wandered through the buildings.

"Ding, you have entered the Library Pavilion."

A system alert suddenly appeared in Lu Ren's mind.

Lu Ren's expression slightly shifted; the system rarely provides environment alerts, so if it does, it indicates there's definitely 'something good' here!

He reached out to crush the old copper lock on the door, but as he exerted force, a golden and peculiar pattern emerged on the lock.

It remained unmoved.

Lu Ren furrowed his brow, then his expression turned serious as the golden rune on the lock started to emit a groaning, overloaded sound.

Suddenly, right under Lu Ren's gaze, the rune shattered, and with the disappearance of the golden rune, the peculiarity on the lock vanished.

Lu Ren wasn't too interested in these array marks. The mere engraving of runes requires extensive practice and consideration of external environment rules, energy changes, and even wind speed.

Too mentally exhausting.

Moreover, the array marks here are too ancient. Although they've endured through ages in the real world and involved divine powers,

some things aren't necessarily better the older they are, especially array marks, which need to be constructed in conjunction with the practical environment.

If not for the vacuum environment on the Moon and the fact that they were buried underground, on Earth, these array marks would have long vanished over time.

The copper lock began to rapidly corrode, within a few seconds appearing rusted with countless specks.

Clang!

A crisp sound echoed, breaking the copper lock.

The sound reverberated, spreading far in the silent underground palace.

Sound?

Lu Ren suddenly realized that in a vacuum state, sound should not propagate at all.

There's an air medium here!

Lu Ren hesitated briefly, ultimately choosing not to remove his helmet, uncertain what gases might be present.

If there were toxic elements rising, it would be quite troublesome.

Although he could now use Bright Sun True Qi to enter an internal breathing cycle, being unaccustomed to it would affect his strength.

He pushed the door and entered.

Due to a long period of inactivity, the door creaked eerily.

Lu Ren remained unfazed as he stepped into the Library Pavilion, greeted by rows of bookshelves filled with various paper books, as vast as the sea.

After just a glance at the bookshelves, Lu Ren focused on the spatial structure of the building.

Strangely, from outside it didn't appear as spacious as it did inside.

Space folding?

What era exactly are these things from?

Contemplating with a slightly heavy heart, Lu Ren walked up to a bookshelf, took out a book, and opened it. The script inside surprised him.

This was the most original script created by Cangjie, not particularly familiar to Lu Ren, except that within the Security Bureau's archives, a book from the oldest of the Three Essences, called Gui Cang, was mentioned.

It encompasses a myriad of strange techniques, but now many have become ineffective due to changes in the global environment.

Lu Ren skimmed through the book, which was introducing the local customs of a place, but a significant part of its script used variations of Cangjie characters.

This book wasn't particularly important.

Carelessly placing the book back on the shelf, Lu Ren looked towards the stairs leading to the upper floors.

He slowly ascended, in the darkness, some shadowy figures flickered around, with a fluorescent stick in hand, dispersing the surrounding darkness.

But there were some unusual noises in the unseen shadow corners.

This was happening in the mental dimension.

In other words, in this strong magnetic field zone, under the state of spiritual perception, this silent environment seemed quite lively.

Remaining unperturbed, Lu Ren viewed the eerie occurrences here as fairly normal for such strange places.

If the strong magnetic field zone were completely silent without any oddities, he might reconsider whether to continue exploring.

With his current powerful spiritual state, these weird disturbances in the magnetic field waves could only do small tricks around the edges, trying to approach him was a fool's errand.

Of course, only Lu Ren at his current realm could say this; if an ordinary person were here, they'd go mad from the mental anomalies after just a few steps.

On reaching the second floor, which was pyramid-like, the space was slightly smaller than the first floor.

He continued the process like on the first floor, casually picking and flipping through some books.

When he saw illustrations of fist and kick practice methods, Lu Ren skimmed through a few pages with mild interest before losing interest.

These are completely unsuitable for current humans.

Have you ever seen the practice methods for Three Heads and Six Arms, with the fist techniques being straightforward without any flexibility?

Some images had wings on the back, six legs, a bird's head on a human body, countless bizarre creatures sketched briefly, yet vividly capturing their essence.

After confirming there was nothing he needed, Lu Ren directly proceeded to the third floor.

To his surprise, the third floor wasn't filled with shelves, but desks, evidently a place for reading and writing.

After ensuring there was nothing noteworthy, Lu Ren headed to the fourth floor along the staircase.

This was the top floor of the building, where only a few bookshelves were placed.

Surprisingly, the shelves held not books but jade-like stones, resembling jade pendants.

Like the jade slips found in cultivation novels?

Lu Ren's heart was stirred as he swiftly approached and picked up one of the jade slips from the shelf. On taking it, golden runes appeared above the shelf.
